What is 35 = -2x - 15 ?
gtnhenbr [62]

Answer:

x=-25

A park has a large circle painted in the middle of the playground area. The circle is divided into 4 equal sections, and each se
oee [108]
First you need to find the area of the whole circle.\pi  r^{2}
The radius is given as 10, so just insert 10 into the equation of the area of a circle equation. 
Area =  \pi  10^{2}    Area =  100 \pi
Putting \pi after the 100 because that is what is commonly done. 

Because the circle is then being split into 4 equal sections, we need to find 1/4 of the area of the whole circle to find the area of one of these sections. 

Since the area of the whole circle is 100 \pi then we just divide that by 4, 
leaving us with 25\pi and that is our final answer

Victoria filled up her car with gas before embarking on a road trip across the country. The car uses 1.75 gallons of gas for eve
lozanna [386]

Answer:

G = 14 - 1.75(t)

Where G is the number of gallons of gas remaining;

14 represents the amount of gas in gallons in the full gas tank of the vehicle

t is the number of hours

Step-by-step explanation:

Here, we want to write an equation.

We are told that the car uses 1.75 gallons of gas every hour and after 4 hours 7 gallons were left

In the 4 hours, the amount of fuel used will be 1.75 * 4 = 7 gallons

So therefore since we have 7 gallons left, the amount of gallons in the full tank of the vehicle will be 7 + 7 = 14 gallons

Hence, the equation we want to write will be;

G = 14 - 1.75(t)
