Step-by-step explanation:

Giveb that :

Perimeter = 5/2 + 8/2 + 5/2 + 8/2

Hence, sum of the perimeter will be ;

The L. C. M of the denominator = 2

(5 + 8 + 5 + 8) / 2

= 26 / 2

Hakim Ellison wants to buy a 4 door sport utility vehicle 4 wheel drive hybrid. There is an 8% sales tax on the purchase price of the SUV in his state. If he pays the full sticker price for the SUV, how much is the total?

Answers

Answer: $60401.16

Step-by-step explanation:

From the attached image, the total price for the vehicle = $55,927.

If he were to pay the full sticker price for the SUV, the total would sum up to

= $55,927 + 8% sales tax

= $55,927 + 8/100( $55,927)

= $55,927 + 0.08($55,927)

= $55,927 + $4474.16

= $60401.16

The total would sum up to $60401.16

There were 43 cars in the race. They all finished the 265 miles of the race and they each used about 1 gallon of gas to go 5 miles. About how many gallons og gas did the cars use altogether to finish the race?

Answers

Answer:

2,279 gallons of gas.

Step-by-step explanation:

Given;

total number of cars in the race, t = 43 cars

total distance traveled by each car, d = 265 miles

5 miles ---------------- 1 gallon of gas

265 miles ------------ x gallon of gas

x = 265 / 5

x = 53 gallons

Total gallons of gas used by the 43 cars in the race is given as;

Total gallons of  gas = 53 gallons x 43 cars

Total gallons of  gas = 2,279 gallons of gas.

Therefore, the toal gallons of gas the cars used altogether to finish the race is 2,279 gallons.

5 StartRoot 3 EndRoot

Answers

Answer:

That is a 45-45-90 triangle next to a 30-60-90 triangle.  

So, the height of the left triangle equals 5.

That makes the short side of the 30-60-90 triangle also equal to 5.

In a 30-60-90 triangle, the hypotenuse (or "x") is exactly twice the length of the shortest side.

Therefore, the hypotenuse (or "x") equals 10.

Given an arc of a sector is three times its radius, find the angle subtended by the arc.​
HELP!!

Answers

Answer:

The angle subtended by the arc is 171.8873385 degrees (3 radians)

Step-by-step explanation:

The formula of the length of an arc of a sector is L = [tex]\frac{x}{360}[/tex] × 2 π r, where

x is the central angle subtended by the arcr is the radius of the circle

∵ An arc of a sector is three times its radius

L = 3r

→ Equate the formula of the length of the arc by 3r

[tex]\frac{x}{360}[/tex] × 2 π r = 3r

→ Divide both sides by r

∴  [tex]\frac{x}{360}[/tex] × 2 π = 3

→ Simplify the left side

∵  [tex]\frac{\pi }{180}[/tex] x = 3

→ Divide both sides by  [tex]\frac{\pi }{180}[/tex]

∴ x = 171.8873385°

The angle subtended by the arc is 171.8873385 degrees (3 radians)
