Answer:
The height is 15 cm. The volume is 6000 cm³
Step-by-step explanation:
The base is square, so the sides are equal.
√400 = 20. This is the length and width of the cuboid.
The area of the base and the area of the top face are equal, so we subtract 2(400) from the total area to get the area of the remaining 4 faces.
2000 - 800 = 1200 cm²
Divide by 4 to get the area of an individual face.
1200/4 = 300 cm²
We found the width earlier: 20cm
We found the width earlier: 20cm300/20 = 15cm. This is the height.
To find Volume, multiply Area of the base times the height:
400cm²×15cm = 6000cm³
Answer:
this is your answer. best of luck.

12.) Rachel is comparing the cost of two parking garages. Garage A charges a flat fee of $6 to park plus $0.50 per hour.
Garage B charges a flat fee of $2 to park plus $1 per hour. Write an equation then find after how many hours will the
cost at garage A and garage B be the same? What will that cost be? (4 points total)
Answers
Answer:
The equation: 6 + 0.5x = 2 + 1x
How many hours till the cost is the same: 8 hours
What will the cost be: $10
Step-by-step explanation:
6 + 0.5x = 2 + 1x
subtract 0.5x from both sides
6 = 2 + 0.5x
subtract 2 from both sides
4 = 0.5x
divide both sides by 0.5
x = 8
Lets check our work:
Garage A:
6 + 0.5(8)
6 + 4 = 10
Garage B:
2 + 1(8)
2 + 8 = 10
After 8 hours the price for both garages will be equal at $10
Solve for x
-18 = 9 - 3x
Answers
Answer:
3x=9+18
=27
x =27÷3
x=9
the answer of x is 9
Rewrite the equation so that the x term is on the left:
9 - 3x = -18
Move the number to the right and change the sign:
-3x = -18 - 9
-3x = -27
Change the sign of both terms:
3x = 27
Move the 3 to the right and change the sign:
x = 27 ÷ 3
x = 9 is your answer.
Aviation:
An airplane goes down from 42,000 feet to 18,000 feet in 12 minutes. What is the rate of change of the altitude in feet per minute?
Answers
Change in altitude:
42,000 - 18,000 = 24,000 feet
Rate of change = 24,000 feet / 12 minutes = 2,000 feet per minute
Because the plane was going down, the rate of change would be negative.
The rate would be -2,000 feet per minute.

Ms. Green has 18 pencils at her desk. Students borrow some of the pencils, and 6 pencils are left at the end of the school day. How many pencils were borrowed?
x - 6 = 18
18 - x = 6
18 + 6 = x
Answers
Answer:
18-x=6
Step-by-step explanation:
because
if you have eighteen and some were borrowed and 6 were left so it will be subtracted
Answer:
18 - x = 6
Step-by-step explanation:
In any equation x is the unkown you are trying to figure out.
In a word-problem-solving question its helpful to set out what you know and what you dont know:
You know the original number of pens = 18
You know the final number of pens = 6
You dont know how many pens were taken.
Therefore x is the difference between 18 and 6.
18 pens take away x pens is equal to 6
hence 18 - x =6

What is the value of x in the triangle? A. 21 B. 10 C. 7 D. 7√3
Answers
Answer:
A.21
Step-by-step explanation:
We can use trigonometry to slove for sides in this triangle...
Using the 60 degree angle...we can solve for x.
We are dealing with adjacent and opposite sides, so we use the tangent function in the calculator.
And since we're using tangent, we have to use opposite/adjacent
We have tan60=x/7sqrt3-multiply the adjacent side(7qrt3) to the other side,
and we have 7sqrt3tan60=x--enter this in to you're calculator, and you should
get an answer of 21

What is the LCM (least common multiple) of 2 and 7
Answers
Answer:
14
Step-by-step explanation:
Answer: 14
Step-by-step explanation:
The greatest common multiple of 2 and 7 is 1, because they are both prime numbers (numbers that cannot be divided by anything other than one or themselves).
Why bother with the greatest common multiple?
There's a very sneaky formula you can do to calculate the LCM with this.
[tex]lcm(a, b) = \frac{|a * b|}{gcd(a, b)}[/tex]
where lcm(a, b) = the least common multiple of integers a and b (1)
a = integer a (2)
b = integer b (7)
gcd(a, b) = greatest common divisor of integers a and b
So let's use it, we have all the available numbers.
[tex]lcm(a, b) = \frac{|2 * 7|}{1} = 14[/tex]
