Answer:

1. x = 24

2. y = 9

3. h = 16

4. r = 15

Step-by-step explanation:

$\frac{4}{8} = \frac{12}{x}$

So 4x = 12 * 8

4x = 96

x = 24

(3/3) = (9/y)

So 3y = 3*9

3y = 27

y = 9

(5/20) = (4/h)

So 5h = 20*4

5h = 80

h = 16

(8/20) = (6/r)

So 8r = 20*6

8r = 120

r = 15

WILL MARK BRAINLIEST

Aneli [31]

Answer: 37 donuts

Step-by-step explanation:

coffee for 2,

donuts for 1.5

c = coffee

d = donuts

lets make an equation

c*2 + (80-c)*1.5 = 141.5

from this we get:

c= 43.

if c = 43, then d is 80-43 = 37.

they sold 43 coffees, and 37 donuts.

lets check the math

43*2+37*1.5 = 141.5. math checks out

The diagram shows a solid which is half of a cone. Calculate the total surface area of the solid.

Vilka [71]

Answer:

<h2>100πcm².</h2><h2>None of the options is correct</h2>

Step-by-step explanation:

Total surface area of a cone $S$ = $\pi r^{2}+\pi rl\\$

Since the diagram is half of a cone, its surface area will be $S = \frac{\pi r^{2} +\pi rl}{2}$

r = radius of the cone

l = slant height

From the diagram diameter of the cone = 16m;

r = 16/2 = 8m

l = 17m

$S = \frac{\pi (8)^{2} +\pi (8)(17)}{2}\\S = \frac{64\pi + 136\pi }{2} \\S = 32\pi + 68\pi \\S = 100\pi cm^{2}$
