70 POINTS PLEASE HELP! A dump truck pours sand into a container in the shape of a rectangular prism with a square base of length 2 feet. SEE PICTURE FOR REST
Answer:
A
Step-by-step explanation:
The volume of a rectangular prism is:
[tex]V=\ell wh[/tex]
Since the prism has a square base, each side length being 2, this means that both the length and width of our prism is 2. Therefore:
[tex]V=(2)(2)h=4h[/tex]
So, we can write:
[tex]V=4h[/tex]
The height h increases at a rate of about 8 inches or 8/12 = 2/3 feet per minute.
So, after t minutes, the height will be 2/3(t) feet. Thus, we can substitute:
[tex]\displaystyle V=4\Big(\frac{2}{3}\Big)t=\frac{8}{3}t[/tex]
We want to find after how long it will be until the volume is 64 cubic feet. So, V = 64:
[tex]\displaystyle 64 = \frac{8}{3} t[/tex]
Solve for t:
[tex]\displaystyle t=\frac{3}{8}(64)=3(8)=24\text{ minutes}[/tex]
The correct answer is A.
12. Given a right triangle with the length
of one leg equal to 9 centimeters and
the length of the hypotenuse equal to
15 centimeters, what is the length of
the other leg?
F 6 cm
H square root of 306 cm
G 12 cm
J 144 cm
Answer:
G. 12 cm
Step-by-step explanation:
Length of one leg of right triangle = a = 9 cm
Length of hypotenuse = c = 15 cm
Length of the other leg = b = ?
Applying pythagorean theorem, c² = a² + b², we have:
15² = 9² + b²
15² - 9² = b²
144 = b²
b = √144
b = 12
Plz I need help this is due at 7:10 and I wasn’t paying attention in class.
Answer:
253cm²
Step-by-step explanation:
Area of the trapezoid = 1/2(b1+b2)*h
Given
h = 22cm
b1 = 10.5cm
b2 = 12.5cm
Substitute
Area of the trapezoid = 1/2(10.5+12.5)*22
Area of the trapezoid = 1/2(23)*22
Area of the trapezoid =11*23
Area of the trapezoid = 253cm²
Hence the area of the trapezoid is 253cm²

3/8 + 1/4 = Tap on the pic to see wiestion
Answer:
3/8 + 1/4 is 5/8 and 1/10+4/5 is 1
Step-by-step explanation:
convert 1/4 to 2/8 and add to 3/8 to get 5/8
convert 4/5 to 9/10 and add to 1/10 equals 10/10 which is also 1
Answer:
9/10 (and 5/8 for question in title)
Step-by-step explanation:
To add fractions, you need to make a common denominator, which you can have a common denominator of 10.
To do this, multiply the numerator (4) and the denominator (5) by 2. You will get 8/10.
Now you can add them together: 8/10 + 1/10 = 9/10
I don't know if you wanted the question in the title answered too so here:
Same thing; common denominator. Use 8. Multiply 1 by 2 and 4 by 2. You get 2/8.
Add: 3/8 + 2/8 = 5/8

Step-by-step explanation:
Z- 6.3 = 2.1
Solve the equation
Answer:
Z = 8.4
Step-by-step explanation:
Jusg move 6.3 behind
When something negative moves behind it becomes positive
So 2.1 plus 6.3 is 8.4
Answer:
Z=8.4
Step-by-step explanation:
1. Add 6.3 to both sides.
Z =2.1+6.3
2.Simplify 2.1+6.3 to 8.4
Z=8.4
--------------------------(Checking answer)
Z−6.3=2.1
1. Let Z=8.4
8.4-6.3=2.1
2. Simplify 8.4-6.3 to 2.1
2.1=2.1

Give the area of land 25m wide and 50m long
The area of the land is 1250 square meters.
What is the area of the rectangle?
To find the area of a rectangle, we multiply the length by the width.
So the formula for finding the area of the rectangle is
Area = Length * Width
In this case, the land is 25 meters wide and 50 meters long, so the area is:
Area = length × width
Area = 50 m × 25 m
Area = 1250 m²
Hence, the area of the land is 1250 square meters.

The circumference of a cylinder is 20 inches and the volume is 600 cubic inches. Calculate the height.
Answer:
h = 18.88 inches
Step-by-step explanation:
Given that,
The circumference of a cylinder is 20 inches
The volume of the cylinder, V = 600 cubic inches
We need to find the height of the cylinder. We know that the volume of a cylinder is given by :
[tex]V=\pi r^2h[/tex]
r is radius
We know that,
circumference = 2πr
[tex]r=\dfrac{C}{2\pi}\\\\r=\dfrac{20}{2\pi}\\\\r=3.18\ \text{inches}[/tex]
So,
[tex]h=\dfrac{V}{\pi r^2}\\\\h=\dfrac{600}{\pi\times (3.18)^2}\\\\h=18.88\ \text{inches}[/tex]
So, the height of the cylinder is 18.88 inches.

Target is having a holiday sale and is marking down

of a TV is given at $500 and the sign in front of the TV
says that price is 25% off the listed price. Determine the
marked down price of the TV.
Answer:
$375
Step-by-step explanation:
Convert the 25% discount into a decimal, which is 0.25Multiply the original listed price ($500) by the discount as a decimal (0.25), which is $125Subtract the original list price ($500) by $125 (the discount as a number). This is $375, which is the answer.At the sewing store, Mia bought a bag of mixed buttons. She got 490 large buttons and 210 small buttons. What percentage of the buttons were large?

Which term makes the equation y=sup(x,3)+2x+1 nonlinear?
Answer:
sup(x,3)
Step-by-step explanation:
Linear equation:
A linear equation has the following format:
[tex]y = ax + b[/tex]
In a linear equation, when x changes by 1, y will always change by the amount a, which is called slope.
In this question:
y=sup(x,3)+2x+1
[tex]y = 2x + 1[/tex] would be a linear equation.
However, the expression sup(x,3), that is, the higher value between x and 3, means that the function is not linear.
