Answer:

The answer is 11.

Step-by-step explanation:

Use PEMDAS

P - Parenthesis

E - Exponents

M - Mulitiplication

D - Divide

A - Add

S - Subtract

So, with that you learn that you solve whatever is in the parenthesis first.

(9 - 3) = 6

Now, divide 20 by 4 which equals 5.

So now the problem is now 6 + 5 which equals 11.

The answer is 11.

Answer:

$V_{composite\: figure} =678.24\: in^3$

Step-by-step explanation:

For a single cylinder:

radius (r) = 3 in (Given)

height (h) = 8 in (Given)

It is given that: all the three cylinders are identical, means their radii and heights are equal.

Thus, the volume of composite figure will be equal to three times the volume of single cylinder.

$\implies V_{composite\: figure} =3(\pi r^2 h)$

$\implies V_{composite\: figure} =3(3.14\times (3)^2 \times 8)$

$\implies V_{composite\: figure} =3(226.08)$

$\implies V_{composite\: figure} =678.24\: in^3$

Please help asap I'm not sure how much time I have

Tan 37,4 = opposite/adjacent

tan 37,4 = x/12,8
• then multiply both sides by 12,8

12,8tan 37,4 = x
Therefore x = 9, 79 x 100
= 97, 86
= 100
( I guess that’s how you can round it to the nearest hundred, please correct me if I’m wrong)

X = t - 3, y equals two divided by quantity t plus five

nekit [7.7K]

X = t - 3 is also -t = -x - 3 or t=x+3

Substitute it in

y=2/t+5
y=2/(x+3)+5

Let y=0 to solve for x

0=2/(x+3)+5
-5= 2/(x+3)
-10=x+3
-7=x

Now solve for t

t = x+3
t = (-7)+3
t = -4

Now we can solve for y

y = 2/(-4)+5
y = -0.5+5
y = 4.5

To check

4.5 = 2/(-4) + 5
4.5 = -0.5 + 5
4.5 = 4.5

-7 = -4 - 3
-7 = -7

Therefore
x = -7
y = 4.5
t = -4
