What is conversion?Conversion means to convert the same thing into different units.
In a test, a hybrid car drove 619 yards on 1 fluid ounce of gasoline.
We know that 1 yard = 1/1760 miles. Then we have
619 yards = 619 x 1 / 1760 miles
We know that 1 fluid ounce = 1 / 128 gallons
The rate in miles per gallon will be
R = (619 / 1760) / (1 / 128)
R = 619 x 128 / 1760
R = 45 miles per gallon
The rate in miles per gallon will be 45 miles per gallon. Then the correct option is D.

1st pic is 2nd q and 2nd pic is for 5th q
Answer:
1.) C
2.) C
3.) D
4.) D
5.) C
Step-by-step explanation:
1.) Each coin has two possible outcomes, and they are two coins in total.
2 (outcomes) x 2 (coins) = 4 possible outcomes
*hint: Look at the 1st column of the diagram and count how many branches come from it
*another hint: The branches are equal to the number of H's and T's in the 2 Column (4 branches or 4 possible outcomes)
2.) Each coin has two possible outcomes, and they are three coins in total.
2 (outcomes) x 3 (coins) = 6 possible outcomes
*hint: Look at the number of branches coming from 3 of the H's and T's in the 2nd column. (6 total branches or possible outcomes)
3.) They are 3 different types of phones, and 3 different types of cases.
3 (phones) x 3 (cases) = 9 possible combinations
{4R,4B,4C,5R,5B,5C,6R,6B,6C,}
*hint: Count 3 cases for each phone and add them (9 total)
4.)Each Dice has 6 sides (cube) and there are 2 Dice. But Each side gets paired with another side, so
6 (sides) x 6 (sides) = 36 possible outcomes
A - Shows outcomes for 1 Dice
B - Shows sum for both Dice
C - Shows some possible combinations when they are both the same number
D - Shows some more possible combinations including those when both dice are not the same number
D Appears to be the best answer as it has more details
5.) 2 Types of bottom wear (shorts or jeans), 3 Types of shirts (red, blue, green) and 2 Types of shoes (flip flops or tennis shoes).
2 (bottom) x 3 (top) x 2 (feet) = 12 possible combinations
*hint: For each bottom wear (shorts or jeans) there are 6 possible combinations so multiplying by two will give you the amount for each one.

The height of a rectangular prism is 3 in.. The perimeter is 88 in. (4 in. wide and 11 in. long). What is the value of the base?
Step-by-step explanation:
Given,
The height of a rectangular prism(h) = 3 in and
The perimeter of a rectangular prism = 88 in
To find, the base of a rectangular prism(b) = ?
We know that,
The perimeter of a rectangular prism = 2l + 2b or 2b + 2h or 2h + 2l
∴ 2b + 2(3) = 88
⇒ 2b = 88 - 6
⇒ 2b = 82
⇒ b = 41 in
Thus, the base of a rectangular prism(b) = 41 in.

Amelia’s hourly wage is $3.50 less than double David’s hourly wage. Write an equation to find David’s hourly wage
The equation to find David’s hourly wage is:
David’s hourly wage = [tex]\frac{1}{2}[/tex] x + 1.75, where x represents Amelia’s hourly wage
Step-by-step explanation:
The given is:
Amelia’s hourly wage is $3.50 less than double David’s hourly wage
We need to find an equation to find David’s hourly wage
Assume that:
Amelia's hourly wage is xDavid’s hourly wage is y∵ Amelia’s hourly wage is $3.50 less than double David’s
hourly wage
- That means multiply David’s hourly wage by 2, then
subtract 3.50 from the product to get Amelia’s hourly wage
∴ x = 2y - 3.50
Now let us find y in terms of x
∵ x = 2y - 3.50
- Add 3.5 to both sides
∴ x + 3.50 = 2y
- Divide each term by 2
∴ [tex]\frac{1}{2}[/tex] x + 1.75 = y
- Switch the two sides
∴ y = [tex]\frac{1}{2}[/tex] x + 1.75
∵ y represents David’s hourly wage
∴ David’s hourly wage = [tex]\frac{1}{2}[/tex] x + 1.75, where x represents
Amelia’s hourly wage
The equation to find David’s hourly wage is:
David’s hourly wage = [tex]\frac{1}{2}[/tex] x + 1.75, where x represents Amelia’s hourly wage

The Murphy family is on a road trip. On the first day, they traveled 30% of their total distance. On the second day, they traveled another 1/4 of the total distance. What fraction of the total distance do they have left after the second day? What percent?
After the second day of their road trip, the Murphy family has
9/20 or 45% of the total distance left to travel.
To solve this problem, let's denote the total distance of the trip as $D$.
On the first day, the Murphy family travelled 30% of the total distance, which can be written as:
[tex]\[ 0.30 \times D = \frac{30}{100} \times D = \frac{3}{10} \times D \][/tex]
On the second day, they travelled another 1/4 of the total distance, which is: [tex]\[ \frac{1}{4} \times D \][/tex]
The total distance travelled after two days is the sum of the distances travelled on the first and second days: [tex]\[ \frac{3}{10} \times D + \frac{1}{4} \times D \][/tex]
To add these fractions, we find a common denominator, which is 20:
[tex]\ total \ distance \ travelled =6/20D+5/20D[/tex]
[tex]\ total \ distance \ travelled =11/20D[/tex]
The remaining distance after the second day is:
Distance left=D−Total distance travelled
[tex]Distance \ left=D-11/20D[/tex]
[tex]Distance \ left=20/20 D-11/20D[/tex]
[tex]Distance \ left=9/20D[/tex]
Express the fraction and percentage of the distance left:
Fraction of the total distance left:
Fraction= Distance left/D
[tex]Fraction=9/20D/D=9/20[/tex]
After the second day, the Murphy family has 9/20 of the total distance left.
Percentage of the total distance left:
Percentage= Distance left/D×100%
[tex]Percentage= 9/20D/D*100%[/tex]
[tex]Percentage=9/20*100%[/tex]
[tex]Percentage=45[/tex]
Therefore, after the second day of their road trip, the Murphy family has
9/20 or 45% of the total distance left to travel.

Answer:
1)m<DCH =89
2)m<BCD=103
Step-by-step explanation:
1) We have that:
m<EFB=91 degree.
We want to find m<DCH.
By same side interior angle property:
m<DCH +m<EFB=180
m<DCH +91=180
m<DCH=180-91
m<DCH =89
2) Given that: m<HFG=103, we seek to find m<BCD.
By the alternate exterior angle property:
m<HFG=m<BCD
Therefore
m<BCD=103

Vince has a rectangular rug in his room with an area of 10 ft the length of the rug is 18 inches longer than the width what could be the dimensions of the rug?
The length of the rug is 4 ft.
The width of the rug is 2.5 ft.
Explanation:
The area of the rug is 10 ft.
The length of the rug be l.
Let us convert the inches to feet.
Thus, [tex]18 inches = 1.5 ft[/tex]
Thus, the length of the rug is [tex]l=1.5+w[/tex]
Let the width of the rug be w.
Substituting these values in the formula of area of the rectangle, we get,
[tex]A=length\times width[/tex]
[tex]10=(1.5+w)(w)\\10=1.5w+w^2\\w^2+1.5w-10=0[/tex]
Solving the expression using the quadratic formula,
[tex]$w=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}$[/tex]
Substituting the values, we have,
[tex]$w=\frac{-15 \pm \sqrt{15^{2}-4 \cdot 10(-100)}}{2 \cdot 10}\\[/tex]
[tex]$w=\frac{-15 \pm \sqrt{4225}}{20}$[/tex]
[tex]$w=\frac{-15 \pm 65}{2 0}$[/tex]
Thus,
[tex]w=\frac{-15 + 65}{2 0}\\w=\frac{50}{20} \\w=2.5[/tex] and [tex]w=\frac{-15 - 65}{2 0}\\w=\frac{-80}{20} \\w=-4[/tex]
Since, the value of w cannot be negative, the value of w is 2.5ft
Thus, the width of the rug is 2.5ft
Substituting [tex]w=2.5[/tex] in [tex]l=1.5+w[/tex], we get,
[tex]l=1.5+2.5\\l=4[/tex]
Thus, the length of the rug is 4 ft.
It's A

Question 2
Sarah opens a savings account that has a 2.75% annual interest rate, compounded monthly. She deposits $500 into the
account. How much will be in the account after 15 years?
$500.00
$754.94
$1255.27
$255.27
Therefore $754.94 will be in account after 15 years.
Step-by-step explanation:
Given , Sarah opens a saving account that has a 2.75% annual interest rate , compounded monthly. She deposits $500 into the account.
P = $500, r = 2.75% = 0.0275 , t = 15 years and n= 12
[tex]Amount (A) =P(1+\frac{r}{n})^{nt}[/tex]
[tex]=\$500(1+\frac{0.0275}{12})^{(12\times15)}[/tex]
=$754.94
Therefore $754.94 will be in account after 15 years.
After 15 years with a 2.75% annual interest rate, compounded monthly, an initial deposit of $500 in a savings account will grow to approximately $754.94.
Explanation:The student has asked how much money will be in a savings account after 15 years with an initial deposit of $500 if the account has a 2.75% annual interest rate, compounded monthly. To calculate the future value of this account, we can use the compound interest formula:
A = P (1 + r/n)^(nt)
Where:
Here, P is $500, r is 0.0275 (2.75% expressed as a decimal), n is 12 (since the interest is compounded monthly), and t is 15 years.
So, the calculation is:
A = $500 * (1 + 0.0275/12)^(12*15)
By computing this, we can determine the future value of the savings account after 15 years:
A ≈ $500 * (1 + 0.00229167)^(180)
A ≈ $500 * (1.00229167)^180
A ≈ $500 * 1.510383954
A ≈ $754.94
Therefore, the amount in the savings account after 15 years will be approximately $754.94.

A person is choosing between two cellphones.Data Plan A has a monthly free of $35 with a charge of $12 per gigabyte(GB).Data Plan B has a monthly fee of $25 with a charge of $17 per GB.
a) for how many GB of data will the costs for the two data plans be the same?what is the cost for each plan?
Answer:
When you use 2 GB
Step-by-step explanation:
Data Plan a Formula 35(12p)
P = per GB
Data Plan B 25(17p)
Set each on equal to each other
Please Check my work, but I think this is on the right track.
The costs for both the data plans A and B will be the same for 2GB of data. The cost for each plan will be $59.
Explanation:This problem is essentially asking us to find the number of gigabytes (GB) at which both data plans A and B cost the same. We can form two equations representing the costs of the plans. For plan A, the cost is $35 + $12 per GB. For plan B, the cost is $25 + $17 per GB. We can express these costs mathematically as: 35+12x=25+17x (where 'x' is the number of gigabytes). By solving this equation for 'x', we subtract 25 from both sides and also subtract 12x from both sides, which gives us 10 = 5x. Dividing by 5 from both sides give us x = 2 GB. So, for 2GB of data, the costs for both the data plans will be the same and the cost for each plan is $35 + 12(2) = $59 for plan A and $25 + 17(2) = $59 for plan B.

Heather is making a blanket for her baby and is going to put a ribbon border around it. The blanket will be 3 feet by 5 feet. The fabric for the blanket cost $1.25 per square yard and the ribbon costs $.50 per foot. What is the approximate total cost for the blanket? A) $1.75 B) $10.08 C) $20.84 D) $26.75 E) $32.48
Answer:
The approximate total cost for the blanket is $10.08 ⇒ B
Step-by-step explanation:
The formula of the area of a rectangle is A = L × W
The formula of the perimeter of a rectangle is P = 2(L + W)
where:
L is the length of the rectangleW is the width of the rectangle∵ The baby blanket shaped a rectangle
∵ The dimensions of the blanket are 3 feet and 5 feet
- Find the area of the blanket
∵ A = 3 × 5 = 15 feet²
- Change feet to yard because the cost is by square yard
∵ 1 foot = [tex]\frac{1}{3}[/tex] yard
∴ 1 foot² = [tex](\frac{1}{3})^{2}=\frac{1}{9}[/tex] yard²
∴ 15 feet² = 15 × [tex](\frac{1}{9})[/tex] = [tex]\frac{5}{3}[/tex] yards²
∴ The area of the blanket is [tex]\frac{5}{3}[/tex] yards²
∵ The fabric cost of the blanket is $1.25 per square yard
∴ The fabric cost = [tex]\frac{5}{3}[/tex] × 1.25
∴ The fabric cost = 2.08333 dollars
∵ Heather is going to put a ribbon border around it
- The length of the ribbon is equal to the perimeter of the blanket
∵ P = 2(3 + 5) = 16 feet
∴ The length of the ribbon is 16 feet
∵ The cost of the ribbon is $0.5 per foot
∴ The cost of the ribbon = 16 × 0.5
∴ The cost of the ribbon = 8 dollars
Now add the fabric cost to the ribbon cost to find the total cost of the blanket
∵ The total cost = 2.08333 + 8
∴ The total cost = 10.08333
- Round it to the nearest cent
∴ The total cost = 10.08 dollars
The approximate total cost for the blanket is $10.08

The chipmunks dropped an acorn from the top of a tree. The acorn was 0.25 kg and had a velocity of 4 m/s when it hit the ground. How much kinetic energy did it have?
Step-by-step explanation:
Given, the chipmunks dropped an acron from the top of a tree. The acron was 0.25 kg and had a velocity of 4 m/s when it hit ground.
Kinetic energy =[tex]\frac{1}{2} m v^2[/tex]
Here m = 0.25 kg and v =4 m/s
Kinetic energy of the acron had =[tex]\frac{1}{2}\times 0.25 \times 4^2[/tex] J
= 2 J
The kinetic energy of the Chipmunk is 2 Joules.
Kinetic energy is the energy than an object possesses due to its motion. It is given by:
Kinetic Energy(KE) = (1/2)mv²
Where m is mass, v is velocity.
Given that m = 0.25 kg, v = 4 m/s, hence:
KE = (1/2)mv²
KE = (1/2) * 0.25 * 4² = 2J
The kinetic energy of the Chipmunk is 2 Joules.
