Answer:
0.25
Step-by-step explanation:
Scale factor = ratio of the sides
Assuming the first rectangle is with shorter side 6,
Scale factor = 1.5/6 = 15/60 = 1/4 = 0.25
Divide the new length by the original length:
The arrow points from 6 to 1.5, so the new length is 1.5 and the original length was 6.
1.5 / 6 = 0.25. The scale factor was 0.25
A solid figure is
separated into two rectangular prisms.
The volume of Rectangular Prism A is
80 cubic feet. Rectangular Prism B has
a length of 6 feet and a width of 5 feet.
The total volume of the solid figure is
200 cubic feet. What is the height of
Rectangular Prism B? Show your work
and explain your answer.
Thank you!
Answer: 4 feet.
Step-by-step explanation:
Their is one rectangular prison divided into two.
The volume of the first one is
V1= L X H X W=80.
Volume of the second one is
V2= L X H X W
V2= 6 X H X 5
V2 = 30H
Now from the question, the total volume is 200cubic feet which means V1 + V2 = 200, recall that V1=80 and V2=30H, so we say;
80+30H=200, collecting the like term we have, 30H=200-80.
30H=120, divide both side by 30
30H/30=120/30
H= 4feet.
Height is 4feet.
Final answer:
To find the height of Rectangular Prism B, subtract Rectangular Prism A's volume from the total volume to get Prism B's volume (120 cubic feet), then divide by the product of its length and width. The height is 4 feet.
Explanation:
The question is about finding the height of Rectangular Prism B given that the solid figure it's part of (when combined with Rectangular Prism A) has a total volume of 200 cubic feet, and that Rectangular Prism A has a volume of 80 cubic feet. Considering volume calculations for rectangular prisms are done using length × width × height, we can find the height of Prism B by isolating height in the formula. Since Prism B has a length of 6 feet and a width of 5 feet, and we know the combined volume of both prisms, we first subtract the volume of Prism A from the total volume to find the volume of Prism B, which is 120 cubic feet (200 cubic feet - 80 cubic feet).
Volume of Prism B = 120 cubic feet. The formula for volume is then applied as follows:
Volume = Length × Width × Height
120 cubic feet = 6 feet × 5 feet × Height
Height = 120 cubic feet / (6 feet × 5 feet)
Height = 120 cubic feet / 30 square feet
Height = 4 feet.
Therefore, the height of Rectangular Prism B is 4 feet.
If the probability that a student is on-time to class is 0.1 and the probability he is on-time or marked tardy on the attendance roster is 0.9, what is the probability he will be marked tardy if the events on-time and marked tardy are mutually exclusive? If A and B are independent?
Answer:
.10 %
Step-by-step explanation:
Final answer:
The probability of being marked tardy when events are mutually exclusive is 0.8, and when they are independent, the probability is 0.09.
Explanation:
The probability that a student will be marked tardy if the events on-time and marked tardy are mutually exclusive is 0.9 - 0.1 = 0.8. When events A and B are independent, the probability of both events occurring is the product of their individual probabilities: P(A and B) = P(A) * P(B). In this case, P(on-time) * P(tardy) = 0.1 * 0.9 = 0.09.

3400 dollars is placed in an account with an annual interest rate of 7.5%. How much will be in the account after 17 years, to the nearest cent?
Answer: 11625.8
Step-by-step explanation:
The total amount in the account after 17 years, with an annual interest rate of 7.5%, is approximately $7420.50.
Explanation:To calculate the amount in the account after 17 years, we use the formula for simple interest: Total future amount (with simple interest) = Principal + (Principal × Interest Rate × Time). In this case, the principal is $3400, the interest rate is 7.5%, and the time is 17 years. Plugging in these values, we get:
Total future amount = 3400 + (3400 × 0.075 × 17)
Calculating this, the total future amount in the account will be approximately $7420.50.

the function f(x)=5x+12 models the amount of money in dollars, makes when cutting loans for x hours. How many dollars will alex for 3 hours of loan-cutting work?
Answer:
$27
Step-by-step explanation:
f(x) = 5x + 12
= 5(3) + 12
= 15 + 12
= 27
Alex will earn $27 for 3 hours of lawn-cutting work, as calculated using the function f(x) = 5x + 12.
Explanation:The function f(x) = 5x + 12 models the amount of money, in dollars, Alex makes when cutting lawns for x hours. To calculate the amount Alex will make for 3 hours of lawn-cutting work, we simply substitute x with 3 in the equation:
f(3) = 5(3) + 12
For instance, events G and H (taking a math class and taking a science class, respectively) from Example 3.9 were shown to be independent by verifying that P(G AND H) = P(G) * P(H). Similarly, events A and B from 'Try It Σ' 3.8, learning Spanish and German, were tested for independence by checking if P(A AND B) = P(A) * P(B).
Thus, f(3) = 15 + 12 which equals $27. Therefore, for 3 hours of work, Alex will earn $27.

Which value of the makes \dfrac{8+h}{10}=1
10
8+h
=1start fraction, 8, plus, h, divided by, 10, end fraction, equal, 1 a true statement?
Answer:
h = 2
Step-by-step explanation:
(8+h)/10 = 1
8+h = 1×10
8+h = 10
h = 10-8
h = 2
The value of h that makes the equation [tex]\(\frac{8+h}{10} = 1\)[/tex] true is (h = 2).h=2 is the value that, when substituted into the equation, ensures that the left side of the equation (8+h) is equal to the right side (10 times 1).
To find the value of h that satisfies the
equation: [tex]\(\frac{8+h}{10} = 1\)[/tex],
we can start by understanding the equation. It represents a fraction where the numerator is the sum of 8 and h, and the denominator is 10. The fraction is set equal to 1, which means both sides of the equation should be equal.
To solve for h, we can cross-multiply, which simplifies to
(8 + h = 10)
Now, to isolate h, we need to get it on one side of the equation. Subtracting 8 from both sides yields (h = 2).
So, when h = 2, the equation becomes
[tex]\(\frac{8+2}{10} = 1\)[/tex] , which simplifies to [tex]\(\frac{10}{10} = 1\)[/tex],
making it a true statement.
In essence, h=2 is the value that, when substituted into the equation, ensures that the left side of the equation (8+h) is equal to the right side (10 times 1). This demonstrates the solution's validity and satisfies the equation's condition.

Kiki has $2.48 in her change purse and $1.69 in her hand. Jordan has $3.05 in his left pocket and $1.09 in his right pocket. Who has more money, and how much more money does that person have? Write your answer in a complete sentence.
Answer:
kiki has $4.17 and jordan has $4.14 kiki has 0.03 more than jordan
Step-by-step explanation:
If you add up the numbers for kiki you get $4.17 and if you do the same for jordan with the numbers they gave you for him you get $4.14 then you just minus 4.17 and 4.14 and thats how you get 0.03.
Answer:
Kiki has $0.03 more than Jordan, meaning Kiki has more money.
Step-by-step explanation: It's simple! Add 2.48 + 1.69 = 4.17 (This is Kiki's total amount) And then add 3.05 + 1.09 = 4.14 (This is Jordan's total amount)
As we can see, Kiki has more money. To find the difference we simply do 4.17 - 4.14 = 0.03 (:

Scott invested a total of $5900 at two separate banks. One bank pays simple interest of 12% per year while the other pays simple interest at a rate of 6% per year. If
Scott earned $540.00 in interest during a single year, how much did he have on deposit in each bank?
Scott had $ 2,800 on deposit at the bank that payed 12% interest.
Answer:
$3100 at 12%$2800 at 6%Step-by-step explanation:
Let x represent the amount on deposit at 12%. Then 5900-x is the amount deposited at 6%, and the total interest earned is ...
12%·x +6%·(5900 -x) = 540
0.06x + 354 = 540 . . . . . . . . eliminate parentheses
0.06x = 186 . . . . . . . . . . . . . . subtract 354
x = 3100 . . . . . . . . . . . . . . . . . divide by 0.06
Scott invested $3100 at 12% and $2800 at 6%.
_____
Quick sanity check
The average interest earned is $540/$5900 ≈ 0.0915 ≈ 9.15%. This is more than the average of 12% and 6%, which is (12+6)/2 = 9 percent. Hence more than half of the money must be deposited at 12%.

of the number of miles she skated in July.
II. The distribution of data is approximately symmetrical in both sets of data.
III.The mode of the number of miles Amanda skated in July is equal to the mode of
the number of miles skated in August.
Answer:
The first statement.
Step-by-step explanation:
Because when you look at the July graph you can see that the highest number of miles is 15 and the lowest number of miles is 1 so the range is 15 - 1 = 14.
When you look at the August graph you can see that the highest number of miles is 13 and the lowest number of miles is 5 so the range is 13 - 5 = 8
So the range of the July month is greater than the range of the August month
