Answer:
646.04 cm³
Step-by-step explanation:
<u>Cube volume formula:</u>
V=l*w*h
V=8*8*8
V=512
<u>Hemisphere volume formula:</u>
V=(4/3πr³)1/2
V=(4/3π4³)1/2
V=128/3
<u>Add both together</u>
128/3 + 512 ≈ 646.04cm³
2(x - 4) + 7(x + 4)
(2x - 2 • 4) + (7x + 7 • 4)
9x + 20
When you are doing distributive property, it can only happen if a number or exponent is before the bracket. From this equation, you can solve for x like so:
7(x+5)-x=42
7x+35-x=42 -Using distributive property (Multiplication)
6x=7 -Collecting like terms.
x= 7/6 -The answer.
Therefore x would equate to 7/6.
Answer:
4 kilometers.
Step-by-step explanation:
Answer: the right cost is $1.05 for a bat and 0.5c for a ball.
Step-by-step explanation:
Let's imagine x in the price of bat and y is the price of the ball
From the infor we know that:
x + y= 1.10 (dollars)
and since the bat is $1 more than the ball we can ensure that:
x - 1 = y
Now we can replace y as follow:
x + x - 1 = 1.10
2x - 1 = 1.10
2x = 1.10 + 1
2x = 2.10
x= 2.10/2= 1.05 (dollars)
