Answer: 26in

s=r*theta

r=s/theta

d=r*2

136ft=r*40pi

r=136/40pi=1.082ft

d=1.082*2=2.1645ft*(12in/1ft)=25.97in

Rounded to nearest in is 26in diameter

If the function 5x+y=1 has the domain (-2,1,6) then what is the corresponding range?
zysi [14]

The corresponding range of the domain is (11, -4, -29)

<h3>How to determine the range?</h3>

The function is given as:

5x + y = 1

Make y the subject

y = 1 - 5x

The domain is given as:

(-2,1,6)

Substitute these values in y = 1 - 5x

y = 1 - 5(-2) = 11

y = 1 - 5(1) = -4

y = 1 - 5(6) = -29

Hence, the corresponding range of the domain is (11, -4, -29)

Marcus is making homemade barbecue sauce. The recipe calls for 3 cups of ketchup for every 1/2 cup of mustard. What is the rate
Yuki888 [10]

Answer: 6 cups of ketchup per cup of mustard

Step-by-step explanation:

Given : The recipe calls for 3 cups of ketchup for every \dfrac12 cup of mustard.

That means , for \dfrac12 cup of mustard. we need 3 cups of ketchup.

By using proportions, if we multiply 2 on both sides ,we get

for  \dfrac12\times 2 cup of mustard. we need 3\times 2 cups of ketchup.

⇒ for  1 cup of mustard. we need 6 cups of ketchup.

Hence, the required rate = 6 cups of ketchup per cup of mustard

Wittaler [7]

Answer:

\huge\boxed{\sf x = 26}

Step-by-step explanation:

The acute angles of a right-angled triangle other than the right angle always add up to 90 degrees.

<u>So, we get:</u>

(48 - x) + (3x - 10) = 90

48 - x + 3x - 10 = 90

-x + 3x - 10 + 48 = 90

2x + 38 = 90

2x = 90 - 38

2x = 52

Divide both sides by 2

x = 52 / 2

x = 26

\rule[225]{225}{2}

Hope this helped!

I don't get it- can someone explain
labwork [276]

Answer:

11 4-passenger cars

Step-by-step explanation:

let 'x' represent the number of 4-passenger cars,then 'x-3' represent the number of 6-passenger cars.

92=4x+6(x-3)

92=4x+6x-18

92=10x-18

92+18=10x

110=10x

x=110/10

x=11

Therefore there are 11 4-passenger cars
