A rectangular prism has a base area of 400 square inches. The volume of the prism is 2,400 cubic inches. What is the height of the prism? (7.9A)
Answer:
6
Step-by-step explanation:
2,400 divided by 4 = 6
Can someone answer one of these rows. It’s volume of prisms.
Answer:
1.
Step-by-step explanation:
base formula
is length × height so that would be 11×4=44
base= 44
height=4
volume= 132
2.
base formula
since its a cube it would be length× hight = 36
base= 36
hight=6
volume =216
3.
base formula
pie×radius^2 so that would be 3.14×1.5^2= 14.80
base 14.80
hight 4
volume= 59.2

You and your friend decide to conduct a survey at your school to see whether students are in favor of a new dress code policy. Your friend stands at the school entrance and asks the opinions of the first 100 students who came to campus on Monday. You obtain a list of all students at the school and randomly select 60 to survey
Your friend finds 34% of his sample in favor of the new dress code policy, but you find only 16%. Which do you believe us more likely to be representative of the school population? Explain your choice.
Answer:
34% in favor of the new dress code
Step-by-step explanation:
Because it has a higher percentage and when there is only 16% of students that doesn't really prove the claim or statement. But, when there is more participating or voting that claim or statement is supported.

Volume = 540 cm
Answer:
are you trying to look for the height or radius?
if you're looking for the height then you'll have to divide the volume by pi and the radius squared
if you're looking for the radius then you'll have to divide the volume by pu and the height and do the squareroot over the whole equation

How many real solutions exist for this system of equations? Y = -x + 1 y = -x2 + 4x − 2 A. Zero B. One C. Two D. Infinite
Answer:
Two solutions
Step-by-step explanation:
Given the functions Y = -x + 1 y = -x² + 4x − 2
Since they are both y values, we will equate them to have:
-x+1 = -x² + 4x − 2
Equate to zero
x²-x-4x+1+2=0
x²-5x+3 = 0
Since the resulting equation is quadratic (highest degree being 2), hence there will be two solutions to the equation
What is the area? Add the measurement of the shape. (ft, ft2, ft3,etc)
First to get it right gets brainliest
Answer:
24ft²
Step-by-step explanation:
Okay, so I don't understand what you're saying by the whole add the measurement thing, so if this is wrong, I'm very sorry.
Anyways, let's begin, the formula for the area of a triangle is base x height ÷ 2 so we just have to plug in our values:
12 x 4 = 48
48 ÷ 2 = 24
So the area of the triangle is 24ft²

11. A bag contains 2 blue marbles and 2 green marbles. What is the probability of drawing a blue marble followed by a green marble, without replacing the first marble before drawing the second marble?
Please show work ty
Answer: your answer should be 50%
Step-by-step explanation: This is because there are only four marbles in the bag total and only 2 are blue and only 2 are green so your chances of pulling out either is 50%
Answer:
33%
Step-by-step explanation:
2 blue marbles + 2 green marbles = 4 marbles
1st draw for blue: 2/4 (2 blue marbles out of 4 marbles)
2nd draw for green: 2/3 (1 less marble from 4, marble not put back in)
2/4 x 2/3 = 4/12 = 1/3 = 0.33 or 33%

Group A parallelogram, Group B Quadrilateral.
Answer: Parallelogram and Quadrilateral.
The two ways of classifying shapes are: Parallelogram and Quadrilateral.
There are different ways to classify an item.
How do one identify the type of quadrilateral?Quadrilaterals can be known by;
It is a polygon with four sides.
Since rectangle is known to be a parallelogram that has four right angles.
A trapezoid is regarded as a quadrilateral with only one pair of parallel sides.
And Parallelograms are known to be shapes that has four sides with only two pairs of sides that are known to be parallel.
So we conclude that Group A parallelogram, and Group B Quadrilateral.

Add it to the initial $17 and you get $20.4
Answer: $20.40
Step-by-step explanation:
Since you're giving a 20% tip, your total will be 120% the price of the shampoo and cut.
17 * 120%
= 17 * 1.2
= 20.4
The total amount of money you spent at the salon and barbershop is $20.40

Jlvesh is analyzing the flight of a few of his model rockets with various equations. In each equation, h is
the height of the rocket in centimeters, and the rocket was fired from the ground at timet = 0, where t is
measured in seconds.
Jivesh also has a more powerful Model B rocket. For this rocket, he uses the equation h=-90t4 + 300t.
When is the height of the Model B rocket 250 centimeters? Round your answers to the nearest
hundredth.
After t =
seconds, the rocket will have reached a height of 250 centimeters.
Answer:
After t = 1.67 seconds, the rocket will have reached a height of 250 centimeters.
Step-by-step explanation:
Given
[tex]h = -90t^2 + 300t[/tex] --- correct expression
Required: When does height = 250 cm
To do this, we have:
[tex]h = 250[/tex]
This gives:
[tex]250 = -90t^2 + 300t[/tex]
Rewrite as:
[tex]90t^2 - 300t + 250 = 0[/tex]
Divide through by 10
[tex]9t^2 - 30t + 25 = 0[/tex]
Expand
[tex]9t^2 - 15t - 15t + 25 = 0[/tex]
Factorize:
[tex]3t(3t - 5) -5(3t - 5) = 0[/tex]
[tex](3t - 5)(3t - 5) = 0[/tex]
This gives:
[tex]3t - 5 = 0[/tex]
Solve for 3t
[tex]3t = 5[/tex]
Solve for t
[tex]t = \frac{5}{3}[/tex]
[tex]t = 1.67s[/tex]

For which equation is s = 6 not the solution?
4 s = 24
9 - s = 4
s + 6 = 12
s - 4 = 2
Answer:
9 - s = 4
Step-by-step explanation:
9 - 6 is 3, not 4, so thats the answer!
The equation is s = 6 not the solution is 9 - s = 4.
What is the equation?An equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.
For which equation is s = 6 not the solution?
1. The solution of the equation 4 s = 24 is;
[tex]\rm4 s = 24\\\\s=\dfrac{24}{4}\\\\s=6[/tex]
2. The solution of the equation 9 - s = 4 is;
[tex]\rm 9 - s = 4\\\\s=9-4\\\\s=5[/tex]
3. The solution of the equation s + 6 = 12 is;
[tex]\rm s + 6 = 12\\\\s=12-6\\\\s=6[/tex]
4. The solution of the equation s - 4 = 2 is;
[tex]\rm s - 4 = 2\\\\s=2+4\\\\s=6[/tex]
Hence, the equation is s = 6 not the solution is 9 - s = 4.

Which shows a correct comparison? A: 5 milliliters > 50 liters B: 2 liters < 200 milliliters C: 100 liters < 1,000 milliliteres D: 3,200 milliliters > 3 liters
Answer:
d
Step-by-step explanation:
Note that
> means greater than
< means less than
for example : 2 < 3 means 2 is less than 3
3 >2 means 3 is greater than 2
To determine which comparison is better we have to convert litre to millimetre
1 litre = 1000mm
A 5 mm > (50 x 1000)
5 mm > 50,000
5 is not greater than 50,000
B. (2 x 1000) < 200 mm
2000 < 200
2000 is not less than 200
C. (100 x 1000) < 1,000
100,000 < 1000
100,000 is not less than 1000
D. 3200 > (3 X 1000)
3200 > 3000
3200 is greater than 3000
