Answer:
175 Miles has to be driven to do the plans cost the same.
Step-by-step explanation:
Assume The Chau Drive Y miles .
We Have Given Two Plans ,
- First Plan = 50$ + 0.19$ × Y
- Second Plan = 57$ + 0.15$ × Y
Now,Put First Plan=Second Plan (When Both Plans Cost The Same)
50$ + 0.19$ × Y = 57$ + 0.15$ × Y
0.04$ × Y = 7 ⇔ Y = 175 Miles
Answer:
15 cm²
Step-by-step explanation:
To find the volume of a prism you multiply the area of the end face (pentagon in this example) by the length (9 cm). Here you would reverse that and divide the volume by the length to find the area. 135/9 is 15 so the area of the pentagon is 15 cm².
<u>In equation form would be:</u>
V=A×L [V=volume A=area L=length]
So if you do inverse operations you would divide the volume by the length to get the area.
V/L=A

Step-by-step explanation:
Culvert is a tunnel, therefore we can use the volume and area formula of a cylinder.
Circumference is given such as 280 cm and the circumference formula of a circle is C = 2*pi*r
Solving for the radius, we have:
280 = 2*3.14*r
r = 280/2*3.14
r = 44.59 cm
Area of one end:
Area = pi*r²
Area = 3.14 * 44.59²
Area= 6,243.2 cm²
The total area is times two of area since there were two ends in the culvert.
Total area = 6243.2 * 2
Total area = 12,486.32 cm²
