An office remodeling project costs $15,880. If you pay $3,680
towards the project, how much do you finance?
Answer:
23.17%
Step-by-step explanation:
The project costs $15,880 of which you contributed $3,680. To know the percentage of how much you finance,
(amount paid / cost)*100%
= (3680/15880)*100%
= (0.231738035)*100%
= 23.1738035%
Thus the amount contributed is 23.17% of the cost.

“An A grade will be given to students having at least 450 total test points. There are two more tests to take before the semester is over. Lesha wants to know what she needs to score in order to get an A. Write and solve an equation to determine what score she needs to average on the next two tests if each question is with 1 point. Explain your reasoning.”
The required average on next two tests are:
[tex]t\geq \frac{450-p}{2}[/tex]
Solution:
An A grade will be given to students having at least 450 total test points
Let p represent her present test point total, and t represent the necessary average on the next two tests
There are two more tests to take before the semester is over
Therefore,
[tex]p+2t\geq 450[/tex]
A grade is given to students having at least 450 total test points
"at least" means greater than or equal to
So we have used greater than or equal to symbol
Solve the inequality for "t"
[tex]p+2t\geq 450\\\\Subtract\ p\ from\ both\ sides\\\\2t\geq 450-p\\\\Divide\ both\ sides\ by\ 2\\\\t\geq \frac{450-p}{2}[/tex]
Thus the required average on next two tests are:
[tex]t\geq \frac{450-p}{2}[/tex]

Find the missing side length, m.
Answer:
m=5
Step-by-step explanation:
Since we know that triangle ABC is similar to QRS, we know that the side lengths will be proportional to one another. As such, we should take a ratio to determine the side length of m.
Choose whole numbers to make the division easier
[tex]\frac{QR}{AB} = \frac{QS}{AC} \\\frac{10}{6} = \frac{m}{3} \\\frac{10*3}{6} =m\\m=10*3/6 = 5[/tex]
The missing side length, [tex]$m$[/tex], is [tex]$\boxed{5}$[/tex].
The missing side length, [tex]$m$[/tex], can be found using the fact that triangles [tex]$ABC$[/tex] and[tex]$QRS$[/tex] are similar. This means that their corresponding side lengths are proportional. We can set up a proportion like this:
(m)/(3)=(10)/(6)
Cross-multiplying, we get:
[tex]$$6m[/tex] =[tex]30$$[/tex]
Solving for [tex]$m$[/tex], we get:
[tex]$$m[/tex] =[tex]5$$[/tex]
Therefore, the missing side length, [tex]$m$[/tex], is [tex]$\boxed{5}$[/tex].

A business woman invests $41,500 into two accounts: one that returns 8% annual interest and one that returns 15% annual interest. After 1 year, she earns $5490. How much did she invest in each account?
$10,500 in the 8% interest account, $31,000 in the 15% interest account.
$11,500 in the 8% interest account, $30,000 in the 15% interest account.
$9,500 in the 8% interest account, $32,000 in the 15% interest account.
$32,000 in the 8% interest account, $9,500 in the 15% interest account.
Answer:
$10,500 in the 8% interest account,
$31,000 in the 15% interest account
Step-by-step explanation:
Let
x ---> the amount invested in the 8% interest account
41,500-x ----> the amount invested in the 15% interest account
we know that
The amount invested in the 8% interest account multiplied by the interest in decimal form plus the amount invested in the 15% interest account multiplied by the interest in decimal form, must be equal to $5,490
so
The linear equation that represent this problem is
[tex]0.08x+0.15(41,500-x)=5,490[/tex]
solve for x
[tex]0.08x+6,225-0.15x=5,490\\0.15x-0.08x=6,225-5,490\\0.07x=735\\x=\$10,500[/tex]
so
[tex]41,500-x=41,500-10,500=\$31,000[/tex]
therefore
$10,500 in the 8% interest account,
$31,000 in the 15% interest account

Determine whether the statement is true of false and support your reasoning:
Mr. Flores has 100 pictures in a photo album. Of these pictures, 20 show his friends, 50 show his family, and 30 show his pet dachshund, Frou-Frou.
Based on this information, the probability of Mr. Flores randomly selecting a picture of Frou-Frou is greater than the probability of randomly selecting a picture of his family.
Answer:
The statement that the probability of Mr. Flores randomly selecting a picture of Frou-Frou is greater than the probability of randomly selecting a picture of his family is FALSE. We can clearly see that the probability of selecting a picture of his family is greater than the probability of selecting a picture of Frou Frou.
Step-by-step explanation:
the probability of randomly selecting a picture of Frou Frou is = 30/100 = 0.3
The probability of randomly selecting a picture of his family = 50/100 = 0.5
The statement that the probability of Mr. Flores randomly selecting a picture of Frou-Frou is greater than the probability of randomly selecting a picture of his family is FALSE. We can clearly see that the probability of selecting a picture of his family is greater than the probability of selecting a picture of Frou Frou.
Astronomers sometimes use angle measures divided into degrees, minutes, and seconds. One degree is equal to 60 minutes, and one minute is equal to 60 seconds. Suppose that ∠J and ∠K are complementary and that the measure of ∠J is 41 degrees, 38 minutes, 9 seconds. What is the measure of ∠K?
Pleaseee answer now!!!
The measure of ∠K is 49 degrees 22 minutes 51 seconds.
Step-by-step explanation:
Given that ∠J and ∠K are complementary.
∠J = 41°38'9".
∠K = ?
When a sum of two angles result is 90°, then it is called as complementary angles.
Since ∠J and ∠K are complementary, then their sum is 90°.
∠J +∠K=90°.
∠K= 90° - ∠J.
=90°60'60" - 41°38'9".
=49°22'51".
∠K= 49 degrees 22 minutes 51 seconds.
What is the quotient 212,960\1000
The quotient of 212,960 divided by 1,000 is 212.960, achieved by moving the decimal point to the left by three places, reflecting the three zeros in 1,000.
Explanation:The question asks to find the quotient when 212,960 is divided by 1,000. To find the quotient, you essentially move the decimal point three places to the left. When dividing by powers of 10, each power of 10 represents the number of places you move the decimal to the left. Therefore, 212,960 divided by 1,000 gives us 212.960. This methodology is similar to the examples provided in the reference where dividing by 10, 100, and 1000 shifts the decimal point to the left by one, two, and three places respectively.
Remember that when multiplying or dividing by powers of 10, the decimal point is moved rather than actually performing the multiplication or division action. This is one of the reasons why working with decimals and powers of 10 is simpler compared to other numbers.

the table shows the distance a small motor scooter can travel using one gallon of gasoline comeplete the table to find the number of miles the scooter can travel for other amounts of gasoline
By using the information that the scooter can travel 118 miles with 1 gallon of gasoline as a reference, we calculate that it can travel 11.8 miles with 0.1 gallons and 1180 miles with 10 gallons.
To complete the table and find the number of miles the scooter can travel for other amounts of gasoline, we can use the given information that the scooter can travel 118 miles with 1 gallon of gasoline as a reference point. We can calculate the mileage for different amounts of gasoline using this information.
Here's how we can complete the table:
Gallon 0.1:
We can calculate the distance for 0.1 gallons by taking 10% of the mileage for 1 gallon:
0.1 * 118 miles = 11.8 miles
Gallon 10:
Similarly, we can calculate the distance for 10 gallons by multiplying the mileage for 1 gallon by 10:
10 * 118 miles = 1180 miles
So, the completed table would look like this:
Gallon 0.1: 11.8 miles
Gallon 1: 118 miles
Gallon 10: 1180 miles
This table provides the number of miles the scooter can travel for different amounts of gasoline, including 0.1 gallons, 1 gallon, and 10 gallons.

A cyclist traveled 9 kilometers per hour faster than an in-line skater. In the time it took the cyclist to travel 45 kilometers, the skater had gone 30 kilometers. What’s the speed of the skater?
Final answer:
The speed of the skater is 18 km/h.
Explanation:
To find the speed of the skater, we can set up a proportion using the information given. Let's let the speed of the skater be x km/h. Since the cyclist traveled 9 km/h faster than the skater, the speed of the cyclist would be x + 9 km/h. Now, we can set up the proportion:
(x + 9 km/h)/(45 km) = x km/h)/(30 km).
To solve this proportion, we can cross-multiply and solve for x:
(x + 9 km/h)(30 km) = (x km/h)(45 km)
30x + 270 = 45x
270 = 45x - 30x
270 = 15x
x = 18
Therefore, the speed of the skater is 18 km/h.

one year, super bowl commercial time sold for 4 million for 30 seconds of air time. What was the price per second? Round to the nearest cent
Final answer:
To calculate the cost per second for a $4 million Super Bowl ad that runs for 30 seconds, divide the total cost by the number of seconds, yielding a cost of approximately $133,333.33 per second.
Explanation:
The question asks us to calculate the cost per second for Super Bowl commercial air time when 30 seconds of air time sold for $4 million. To find the price per second, we divide the total cost by the total number of seconds.
Price per second = Total cost ÷ Number of seconds
Price per second = $4,000,000 ÷ 30 seconds
Price per second = $133,333.33 (rounded to the nearest cent)
Therefore, the price per second for Super Bowl commercial air time was approximately $133,333.33.

Thank you
a) Wayne's savings before he spent $28 is $30
b) Stef's savings after she spent $28 is $8
Step-by-step explanation:
step 1 :
let,
Wayne's savings = 5x
Stef's savings = 6x
step 2 :
After spending $28 each of them, The ratio becomes 1/4.
⇒ (28 - 5x) / (28 - 6x) = 1/4
⇒ 4(28 - 5x) = 1 (28 - 6x)
⇒ 112 - 20x = 28 - 6x
⇒ 112 - 28 = 20x - 6x
⇒ 84 = 14 x
x = 84/4 = 6
step 3 :
a) Wayne's savings before he spent $28 = 5x
substitute x=6,
Wayne's savings = 5(6) = $30
step 4 :
b) Stef's savings after she spent $28 = Total savings - $28
= 6x - 28
= 6(6) - 28
∴ Stef's savings after she spent $28 = 36 - 28 =$8
(a) Wayne's savings before he spent $28 is $30.
(b) Stef's savings after she spent $28 is $8.
Solution:
Ratio of Wayne's savings to Stef's savings = 5 : 6
Let x be the common amount they have.
After spending $28 each, the ratio becomes 1 : 4.
5x – 28 : 6x – 28 = 1 : 4
This can be written in a fraction form.
[tex]$\Rightarrow\frac{5x-28}{6x-28}=\frac{1}{4}[/tex]
Do cross multiplication.
[tex]$\Rightarrow 4(5x-28)}=1({6x-28})[/tex]
[tex]$\Rightarrow 20x-112=6x-28[/tex]
Arrange like term one side.
[tex]$\Rightarrow 20x-6x=112-28[/tex]
[tex]$\Rightarrow 14x=84[/tex]
⇒ x = 6
(a) Wayne's savings before he spent $28 = 5x = 5(6) = $30
(b) To find stef's savings after spent $28:
Stef's savings before she spent $28 = 6x = 6(6) = $36
Stef's savings after she spent $28 = $36 – $28 = $8
Hence Wayne's savings before he spent $28 is $30
Stef's savings after she spent $28 is $8.
