Answer:
5x-18=4x+7 ( vertical opposite angle)
5x-4x=7+18
x=25
Answer:
0.350
Step-by-step explanation:
Confidence interval = point estimate ± margin of error
Point estimate = Confidence interval - margin of error
To get the margin of error, we will take the average of the difference of the interval given. Given the confidence interval 0.325<p<0.375
Margin of error = 0.375-0.325/2
Margin of error = 0.050/2
Margin of error = 0.025
Using the interval of 0.375
Point estimate = 0.375 - 0.025
Point estimate = 0.350
<span>You are under contract to design a storage building with a square base and a volume of 12000 cubic feet. the cost of materials is $4 per square foot for the floor, $18 per square foot for the walls and $6 per square foot for the roof. find the width of the square base that minimizes the cost of materials.

Answer:
4.20
Step-by-step explanation:
First find the total cost of the nametags
105 * .12
12.60
Then divide by the 3 teachers
12.60/3 =4.20
Each teacher will pay 4.20
