Step-by-step explanation:
You would multiply 3 by 3 for the base, giving you 9. Then, 3 by 4 for the side which would give you 12, but you have to divide by 2 since it is a triangle. Multiply by 4, the amount of sides, and you get 24. Add it with the base and you get 33.

You are going to plot the point on the number 6 on the x-axis.
Step-by-step explanation:
The point shown to you is an ordered pair. When plotting, ordered pairs have a composition of the x coordinate and the y coordinate (x, y). This means that 6 is the x-value and lies upon the x-axis. Since the y-value is zero, you just have to plot the point on six on the x-axis (the horizontal axis).

A box without a top is to be made from a rectangular piece of cardboard, with dimensions 4 in. by 8 in., by cutting out square corners with side length x and folding up the sides.
Write an equation for the volume V of the box in terms of x.
Use technology to estimate the value of x, to the nearest tenth, that gives the greatest volume. Explain your process.
Answers
Step-by-step explanation:
the answer is in the three pics
The value of x for the greatest volume is 1.5 in.
What is volume?Volume is the measure of the 3-dimensional space occupied by matter, or enclosed by a surface, measured in cubic units.
Given that, A box without a top is to be made from a rectangular piece of cardboard, with dimensions 4 in. by 8 in., by cutting out square corners with side length x and folding up the sides.
v = x(8-2x)(10-2x)
v = x(4x²-36x+80)
v = 4x³-36x²+80x
Now,
The greatest volume will occur when the velocity of v(x) is zero.
dv/dx = 12x²-72x+80
dv/dx = 0 when
x = (72±√1344)/24
Since, 0 < x < 4 (because of the constraints on x for volume to have meaning)
x ≈ 1.5 in
Hence, the value of x for the greatest volume is 1.5 in.

Tamara finds the sum of two number cubes rolled at the same time. The chart below shows all possible sums from the 36 possible combinations when rolling two number cubes. How many times should Tamara expect the sum of the two cubes to be equal to 3 if she rolls the two number cubes 180 times?
Answers
Answer:
Tamara should expect the sum of the two cubes to be equal to 5 20 times.
Step-by-step explanation:
The sample space of rolling a number cube are:
S = {1, 2, 3, 4, 5, 6}
If two such cubes are rolled together, then the sum of the two cubes will be 5 for the combinations below:
S₁ = {(1, 4), (2, 3), (3, 2) and (4, 1)}
The total number of outcomes will be, N = 36.
Compute the probability that the sum of rolling two numbered cubes as follows:
Let X = number of time the sum of the two numbers on two cubes is 5.
Two numbered cubes are rolled n = 180 times.
The event of getting a sum of 5 in independent of the other results.
The random variable X follows a Binomial distribution with parameters n = 180 and p = .
The expected value of X is:
Compute the expected number of times Tamara expects the sum of the two cubes to be equal to 5 as follow:
Thus, Tamara should expect the sum of the two cubes to be equal to 5 20 times.

The play area in a local school is a rectangle that is 18’ x 40’ in size. The management about it to put a 4-foot side walk all around the building, leaving a 2-foot space for plants between the building and the sidewalk. Give the perimeter of the outer edge of the sidewalk and the area of the sidewalk itself?
Answers
Answer:
528 is the Area
148 is the Perimeter
Step-by-step explanation:
We know that there is a 4 foot ring around the building so we add 8 feet to 18 x 40 which is 26 x 48.
To find the perimeter we take the Length and Height times 2 and then add that together.
26•2=52
48•2=96
52+96=148
148 is the Perimeter.
To find the area of the sidewalk.
We have to multiply the area together.
4•48=192•2=384
18•4=72•2=144
528
Add that together you have the area of the sidewalk
