Please help meee, this is my homework . (Geometry) ... I’ll rate brainliest
Rama09 [41]

1. Volume of the sphere


V = \frac 4 3 \pi r^3 =  \frac 4 3 \pi ( 8^ 3) = \dfrac{2048 \pi}{3} \approx 
2144.66


Choice c


2. Algebra making a token effort to pretend to be geometry. Complementary angles add to 90 degrees.


(x+1) + (x-3)=90


2x -2 = 90


2x = 92


x = 46


Angles x+1=47 and x-3=43


Choice b


3. midpoint A=-5, E=5


The midpoint is just the average of A and E, here zero, point D


choice b


4. I can't really tell if x is supposed to be an angle or a length in this figure; presumably a length. I suppose we're to assume parallel lines; so this makes similar shapes, i.e. a proportionality:


\dfrac{24}{x} = \dfrac{36}{12} =3


x = \dfrac{24}{3} = 8


Choice a

6m-2(7+3m)>5(2m-3)-m
Tpy6a [65]

Answer:

Therefore the value is

m

Step-by-step explanation:

Given:

6m-2(7+3m)>5(2m-3)-m ....Given

Step 1. Applying Distributive Property A(B+C)=AB+AC we get

6m-2\times7-2\times 3m>5\times 2m-5\times 3-m

6m-14-6m>10m-15-m\\-14>9m-15

Step 2. Add 15 both the side

-14+15>9m-15+15\\1>9m

Step 3. Dividing both the side by 9

\dfrac{1}{9}>\dfrac{9m}{9}\\\\\dfrac{1}{9}>m

Therefore the value is

m

(fg)-1(5)=g-1f-1(5)​
larisa86 [58]

Answer:

<em>f = g/ g+1</em>

Step-by-step explanation:

Remove Parenthesis.

<em>fg - 1  x 5  = g  - 1  x f  - 1 x 5</em>

Cancel <em>-1 x 5</em> on both sides.

<em>fg =  g - 1  x f</em>

Simplify <em>1 x f</em>  to f.

<em>fg =  g - f</em>

Add <em>f </em>to both sides.

<em>fg + f = g</em>

Factor out the common term <em>f.</em>

<em>f (g + 1)  = g</em>

Divide both sides by <em>g + 1</em>

<em>f =  g/ g + 1</em>

A missile travels at a constant rate of 15,000
Alex777 [14]

Answer: 1000 hours.

Step-by-step explanation: To travel 9 x 10^8 feet, it would take (9 x 10^8)/15000 minutes. This equals 60000 minutes. We divide this number by 60 to convert to hours. This equals 1000 hours.
