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
Answers
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.

What is the sum of the matrices shown below?
[4 19 -5]+[-8 7 0]=
[7 0 -14] [-1 17 6]
Answers
Answer:
-4 26 -5
6 17 -8
Step-by-step explanation:
The matrix addition is
First row: [-4 26 -5]
Second Row: [ 6 17 -8]
What is Matrix Addition?To add two or more matrices, the basic process is matrix addition. Matrix addition is only possible if the matrices are in the same order. By order, we mean that the matrices have the same number of rows and columns. As a result, we can add the matrices' appropriate elements. Matrix addition is not possible if the order is changed.
We will add the rows:
Addition of First row
4 + (-8) = 4- 8= -4
19 + 7 = 26
-5 + 0= -5
Addition of Second row
7 + (-1) = 7- 1= 6
0 + 17= 17
-14 + 6 = -8

When adding integers with the same sign, add the absolute values of the integers.
True or False?
Answers
Answer:
False. This only goes with integers that are both positive.
Step-by-step explanation:
For example, 7+6 is the same as |7|+|6|, which is, again, the same as 7+6.
However, when you add integers that are both negative, you're subtracting, and you'll always end up with a negative difference. Absolute values are always positive, which is why this doesn't work.
(-7)+(-6)
= -7-6
= -13
|-7|+|-6|
= 7+6
= 13

Answer:
The Pink square, Green Rectangle, and the Orange figure
Step-by-step explanation:
The only one I'm not to sure about is the trapezoid, but you can rule out all the others because there is no right angle. Hope this helps!
The Pink square, Green Rectangle, and the Orange figure have at least 1 right angle.
What is rectangle?
In Euclidean plane geometry, a rectangle is a quadrilateral with four right angles. It can also be defined as: an equiangular quadrilateral, since equiangular means that all of its angles are equal; or a parallelogram containing a right angle.
What is square?
A rectangle with four sides of equal length is a square.
What is right angle?
A right angle is an angle that is exactly equal to 90 degrees in measure.
According to question, we have to find which shapes have at least 1 right angle.
In the given figure, we can see that the pink square, green Rectangle, and the orange figure have at least 1 right angle or have [tex]90[/tex] degree in them.
Hence, we can conclude that the Pink square, Green Rectangle, and the Orange figure have at least 1 right angle.

A 6-POUND BAG OF CANDY COSTS $11.28 WHAT IS THE COST PER POUND? 10
Answers
Answer:
$1.88
Step-by-step explanation:
11.28 / 6 = 1.88
Answer: $1.88
Step-by-step explanation:
We have 6 pounds of candy that cost 11.28, and we need to find the unit rate.
If we want to find the unit rate, or the cost per pound, we can use the equation 11.28 ÷ 6.
We can then divide each side by 6, or solve the equation.
11.28 ÷ 6 = 1.88.
Therefore, the each pound of candy costs $1.88.
