What is the value of 7r + 6(r + 2s) when r = 4 and s = 2?

Answer:

Surface Area of the Cylinder is 1156.11

Step-by-step explanation:

To find the Surface Area of a Cylinder, the equation given is  A = 2πrh+2πr2

Given the radius and height of the cylinder, we plug those numbers into the equation to get;

A = 2π(8)(15)+2π(8)2

= 1156.11

Answer:  

1155.52 cm²

Step-by-step explanation:

SA = LSA (Pb x h) + 2B                  

- r = 8 cm, h = 15, π (pi) = 3.14

Lateral Surface Area (LSA) = Pb (Perimeter of base) x h (height)

8 x 2 = 16 x 15 = 240 x 3.14 = 753.6

Area of the Base x 2 = πr² x 2

8² x 3.14 = 64 x 3.14 = 200.96 x 2 = 401.92

753.6 + 401.92 = 1155.52

Step-by-step explanation:

12 shots in 5 minutes.

12/5 ratio.

how long for 5 shots ? x minutes

5/x must be the same ratio as 12/5

so,

5/x = 12/5

25/x = 12

25 = 12x

x = 25/12 = 2 1/12 ≈ 2.08 minutes =

= 2 minutes and 5 seconds

(60 seconds per minute divided by 12 = 5)

Answer:

31 1/2

Step-by-step explanation:

average speed = distance/time

average speed = (73 1/2 miles)/(2 1/3 hours)

= (147/2 miles)/(7/3 hours)

= 147/2 * 3/7 miles/hour

= 441/14 miles/hour

= 31 1/2 miles/hour

Answer:

-(x-8)*(x+7)

Step-by-step explanation:

Use the commutative property

-× to the power of 2 + x+ 56

-x to the power of 2 + 8x-7x+56

-xx(x-8)-7x+56

-x*(x-8)-7(x-8)

factor out -(x-8)

-(x-8)*(x+7)

hope it helps!!

Answer: The answer is 56+−1^2

Answer:

$279.46

Step-by-step explanation:

to solve this equation you have to multiply 35.6 to 7.85

35.6 * 0.05 = 1.78

35.6 * 0.8 = 28.48

35.6 * 7 = 249.2

1.78 + 28.48 + 249.2 = $279.46

Answer:

8 bags

Step-by-step explanation:

It is given that, a make-your-own ice pop kit says to pour 4 fluid ounces of juice into each bag.

We need to find the number of ice pop bags we can fill with 1 quart of juice.

We know that,

1 quart = 32 ounces

We have  32 ounces of juice and each bag contains 4 fluid ounces.

Therefore, 8 ice pop bags we can  fill with 1 quart of juice.

Step-by-step explanation:

D = b² - 4ac

D = 10² - 4 · 3 · 2

D = 100 - 24

D = 76

D = (-5)² - 4 · 1 · (-4)

D = 25 - (-16)

D = 26 + 16

D = 42

D = 7² - 4 · 1 · (-8)

D = 49 - (-32)

D = 49 + 32

D = 81

D = 0² - 4 · 1 · (-9)

D = 0 - (-36)

D = 36

D = (-6)² - 4 · 5 · 10

D = 36 - 200

D = - 164

Answer:

83505

Step-by-step explanation:

It's already in the expanded form...

The price of the food on the menu will be set at $21.

Cost of food item = $6.78

Food cost percentage = 33%

Let the price on the menu be represented by x.

Therefore, based on the information given, the equation to solve the question will be:

= 33% × x = $6.78

33/100 × x = $6.78

0.33 × x = $6.78

0.33x = $6.78

x = $6.78/0.33

x = $20.54

x = $21 approximately

Therefore, the price of the food on the menu will be set at $21.
