Answer:
1200 cubic units
Step-by-step explanation:
If you split the shape into two parts, you can find the volume of each and solve. For the first part, you do 10x8x6 to get 480. For the second part you do 12x10x6 to get 720. Add 480+720 to get 1200.
Hope it helps!

Is 3 a solution to 4x - 3<5?
Answer:
To solve this
4x-3<5
4x<5+3
4x<8
x<8/4
x<2
so no, three is not a solution
Step-by-step explanation:
Answer: No
Step-by-step explanation:
X = 3
Replace the variable X with 3
4 x 3 - 3 (less than or equal to) 5
4 x 3 = 12 - 3 = 9
9 is not equal to or less than 5, thus 3 is NOT a solution

angle A and angle B are vertical angles. If m_A = (7x – 6) and m B = (8x – 27), then find the measure of angle b
Answer:
A = B; 7x - 6° = 8x -27°; x = 21°. So B = 8·21° - 27° = 141°

A student has a container with a volume of 0.5 liter. He estimates the volume to be 0.4 liter. By what percent is the student's estimate off?
Answer:
20
Step-by-step explanation:
0.5-0.4=0.1,0.1/0.5×100= 20
The students's estimation is 80%.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given that a student has a container with a volume of 0.5 liter.
He estimates the volume to be 0.4 liter.
Now to find the percentage of estimation,
estimated volume = correct volume × required percentage / 100
0.4 = 0.5 × required percentage / 100
Required percentage = 0.4 × 100 / 0.5
Required percentage = 0.4 × 100 / 0.5
Required percentage = 80%
Therefore, the students's estimation is 80%.

HELP ILY A tree is 4 1/2 feet tall. It is expected to grow by 1 3/4
feet per year.
At this growth rate, how many years will it take for the tree to have a height greater than 40 feet? Enter the answer in the box.
years
Answer:
It will take 21 years.
Step-by-step explanation:
First, find what x would be for it to equal 40 feet. This can be done with the equation 4.5 + 1.75x = 40.
4.5 + 1.75x = 40
Subtract 4.5 from both sides. This cancels out the +4.5.
1.75x = 40 - 4.5
Subtract 4.5 from 40 to get 35.5.
1.75x = 35.5
Divide both sides by 1.75. This cancels out the *1.75.
x = 35.5/1.75
Expand 35.5/1.75 by multiply both the numerator and denominator by 100.
x = 3550/175
Reduce 3550/175 by canceling out 25.
x = 142/7 = 20 2/7
Go up by one from 20 to get the answer of 21 years.

Are 5x and 5x^2 like terms? Explain your answerc
Answer:
No. 5x and 5x² are not like terms.
When a variable is raised to two different powers, they can not be added together.
Another way to look at it is to note that:
5x + 5x² ≡ 5x(1 + x)
It is more obvious there that 1 and x are not like terms, thus neither are 5x and 5x², though they do have common factors.

w=?????????
Answer:
-3.33333
Step-by-step explanation:
-3w - 4 = 3 + 3
Combine like terms
-3w - 4 = 6
Add 4 on both sides
-3w - 4 + 4 = 6 + 4
-3w = 10
Divide by -1 to isolate the variable
-3w/-3 = 10/-3
w = - 3.33333 ( the 3 keeps repeating)

Evaluate the function:
f(x)=x2−4x, find f(−3)
Answer:
f(-3) = 21
Step-by-step explanation:
To solve this, you can replace all x's with -3 and then solve to find the answer.
f(x) = x^2 - 4x
f(-3) = -3^2 - 4(-3)
f(-3) = 9 - (-12)
f(-3) = 21
