Answer:
2 students are wearing shirts other than blue shirts or white shirts.
Step-by-step explanation:
3/10 of 20 is 6, so 6 people are wearing blue shirts. 3/5 of 20 is 12, so 12 students are wearing white shirts. 6 + 12 = 18. 20 - 18 = 2.

Step-by-step explanation:
Angle GHI + Angle IHK = 180 (Angles on the same straight line)
(x + 30) + (x+10) = 180
x+x+30+10 = 180
2x + 40 = 180
Answer:2x+40=180
Step-by-step explanation:
You want to equate everything for 180 since it's on a straight line
Therefore
(x+30)+(x+10)=180
x+x+10+30=180
2x+40=180

The cost for a business to make greeting cards can be divided into one-time costs (e.g., a printing machine) and repeated costs (e.g., ink and paper). Suppose the total cost to make 500 cards is $1,100, and the total cost to make 650 cards is $1,400. What is the total cost to make 1,000 cards? Round your answer to the nearest dollar.
Answer:
$2100
Step-by-step explanation:
We can make direct use of the fact that the repeated costs are proportional to the number of cards. That lets us write an equation based on the change in cost.
SetupThe change in cost per card from 500 to 650 cards will be the same as the change in cost per card from 500 to 1000 cards. Using c as the cost to make 1000 cards, we have ...
(1400 -1100)/(650 -500) = (c -1100)/(1000 -500)
SolutionMultiplying by (150)(500), we have ...
500(300) = (150)(c -1100)
1000 = c -1100 . . . . . divide by 150
2100 = c
The total cost to make 1000 cards is $2100.
Additional comment
One of the intermediate equations shows us it costs $1100 to make 500 cards and $1000 to make 500 additional cards. This tells us the one-time costs are $100, and the repeated costs are $2 per card. You notice we did not actually have to find these values in order to solve the problem.

y is inversely proportional to d²
When d = 10, y = 4
d is directly proportional to x²
When x = 2, d = 24
Find a formula for y in terms of x.
Give your answer in its simplest form.
Answer:
y = 100 / (9x⁴)Step-by-step explanation:
y is inversely proportional to d²
y = k/d²When d = 10, y = 4:
4 = k/10² k = 400y is:
y = 400/d²d is directly proportional to x²
d = mx²When x = 2, d = 24
24 = m*2²m = 24/4m = 6d is:
d = 6x²Find a formula for y in terms of x:
y = 400 / d² = 400 / (6x²)² = 400 / (36x⁴) = 100 / (9x⁴)Again sorry another question)

What is the area of the isosceles trapezoid in square feet?
Answer:
Area = 20 sq.ft
Step-by-step explanation:
here's your solution
=> Area = 1/2(sum of parrel side)* distance between them
=> Area = 1/2 (8+2) * 4
=> Area = 1/2*10*4
=> Area = 20 sq.ft
