Find the surface area of a cube is 150 cm2. What is the length an edge of
the cube? (all of the sides are squares)
Answer:
5
Step-by-step explanation:
The formula is 6x^2
If you set it equal to 150
Answer:
5 x 5 + 5 x 5 + 5 x 5 + 5 x 5 + 5 x 5 + 5 x 5 = 25 + 25 + 25 + 25 + 25 + 25 = 50 + 50 + 50 = 150
5 would be the missing side because it fits the formula
(A x A) + (A x A) + (A x A) + (A x A) + (A x A) + (A x A) = Surface area

14. The water level in a tank can be modeled by the function h(t)=8cos +11.5, where t is the number of
hours since the water level is at its maximum height, h. How many hours pass between two consecutive
times when the water in the tank is at its maximum height?
I
Answer:
2π hours
Step-by-step explanation:
Given the following function:
h(t)=8*cos(t) + 11.5
we want to find its period. This function has the following form:
y = A*cos(B(x + C)) + D
where:
A = 8
B = 1
C = 0
D = 11.5
which period is computed as: 2π/B. Then, for the case of the problem:
period = 2π/1 = 2π hours

A biased coin is tossed 40 times. Out of those 40 tosses, the coin landed on heads 12 times.
Find the probability of the coin landing on tails.
Answer:
Step-by-step explanation:The probability of picking the biased coin: P(biased coin)=1/100. The probability of all three tosses is heads: P(three heads)=1×1+99×18100. The probability of three heads given the biased coin is trivial: P(three heads|biased coin)=1.
Which of the following equations represents the line graphed below?
Answer:
y= -2x +3
Step-by-step explanation:
This is because the slope is 2 using rise over run and the y-intercept is 3 because it meets at that point, (0,3) on the number line.
Answer:
y= -2x +3
Step-by-step explanation:
How? We have to take a good look at the line graph
So we know that Y is equals to 2x +3 (first option)

James is putting 24 jelly beans into equal rows. He says there will be more jelly beans in 2 equal rows
than in 3 equal rows. Is James correct? Explain.
Select the correct answer below, and fill in the answer box(es) to complete your choice.
(Type a whole number.)
OA. Yes. James is correct. There are fewer rows, so there will be more in each row. There will be
jelly beans in each row for 2 equal rows, and jelly beans in each row for 3 equal rows.
OB. No. James is not correct. There are fewer rows, so there will be fewer in each row. There will be
jelly beans in each row for 2 equal rows, and jelly beans in each row for 3 equal rows.
OC. No. James is not correct. It doesn't matter how many rows there are. There will always be
jelly beans in each row.

Answer:
(A)James is correct.There are fewer rows, so there will be more in each row. There will be 12 jelly beans in each row for 2 equal rows, and 8 jelly beans in each row for 3 equal rows.
Step-by-step explanation:
James is putting 24 jelly beans into equal rows.
If he puts the jelly beans in 2 equal rows:
Number in each row=24/2=12 jelly beans per row.
If he puts the jelly beans in 3 equal rows:
Number in each row=24/3=8 jelly beans per row.
Therefore, James is correct.There are fewer rows, so there will be more in each row. There will be 12 jelly beans in each row for 2 equal rows, and 8 jelly beans in each row for 3 equal rows.
The correct option is A.

Provide the intervals and frequencies you would use to construct the histogram for this data set.
Answer:
39
Step-by-step explanation:
To find the intervals you will need to find the lowest and highest numbers, in this case, it would be 1 and 35. A general rule would be 5-7 intervals, I will use 5.
Here are the intervals with the number of people that were in each:
1-7 (9)
8-14 (14)
15-21 (8)
22-28 (3)
29-35 (5)

UPS charges $6.00 for the first pound, $1.00 for the second pound, and $0.15 for each additional pound. FedEx charges $4.00 for the first pound, $2.00
for second pound, and $0.25 for each additional pound. How many pounds, p. will it take for UPS and FedEx to cost the same?
Complete the equation that represents this situation.
Answer:
12 pounds
Step-by-step explanation:
It takes 12 pounds for the UPS and FedEx packages to cost the same amount to ship.
What is equation?An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, UPS charges $6.00 for the first pound, $1.00 for the second pound, and $0.15 for each additional pound. FedEx charges $4.00 for the first pound, $2.00 for the second pound, and $0.25 for each additional pound.
Equations to represent the situation in this problem.
x=weight of package
UPS cost=6+1+0.15(x-2)
UPS cost=6+1+0.15x-0.3
UPS cost=6.7+0.15x
FedEx cost=4+2+.25(x-2)
FedEx cost=4+2+0.25x-0.5
FedEx cost=5.5+0.25x
Next, we can set the two equations equal to each other to solve for x.
6.7+0.15x=5.5+0.25x
6.7+0.15x-5.5=5.5+0.25x-5.5
1.2+0.15x-0.15x=0.25x-0.15x
1.2/0.1=0.1x/0.1
x=12
Hence, It takes 12 pounds for the UPS and FedEx packages to cost the same amount to ship.

A company is trying to calculate the amount of
concrete that will be needed to create one concrete
block that is in the form below.
The concrete block is a rectangular prism with two
cubes cut out. The cubes have a side length of 6
inches.
What is the total volume, cubic feet, of concrete
needed to make this block?
Answer:
[tex]0.19\,\,cubic\,\,feet[/tex]
Step-by-step explanation:
Given:
The concrete block is a rectangular prism with two cubes cut out. The cubes have a side length of 6 inches.
To find: total volume, cubic feet, of concrete needed to make this block
Solution:
Side of cube = 6 inches
Volume of cube = [tex](side)^3=6^3=216\,\,cubic\,\,inches[/tex]
So, volume of two cubes = 2(216) = 432 cubic inches
Length of rectangular prism = 12 inches
Breadth of rectangular prism = 8 inches
Height of rectangular prism = 8 inches
Volume of rectangular prism = length × breadth × height = [tex]12(8)(8)=768 \,\,cubic\,\, inches[/tex]
Total volume of concrete needed to make this block = Volume of rectangular prism - Volume of two cubes = 768 - 432 = 336 cubic inches = [tex]\frac{336}{1728} =0.19\,\,cubic\,\,feet[/tex]
( use 1 cubic inch = [tex]\frac{1}{1728} \,\,feet[/tex])

Amount earned in compound interest = P(1 + r)^n;
where P is the principal,
r is the rate and n is the number of periods.
Amount = 3,000(1 + 14%)^6 = 3,000(1 + 0.14)^6 = 3,000(1.14)^6 = $6,584.91

Which compound inequality is equivalent to the absolute value inequality |b| greater than 6? –6 > b and b > 6 b > –6 or b < 6 –6 < b and b > 6 b < –6 or b > 6
Answer:
The correct inequality is: b< -6 or b > 6
Step-by-step explanation:
The absolute value operator always results in a positive number, in such a way that if b > 0, then |b| = b, while if b < 0, then |b| = -b. With this in mind, let's look at the inequality given:
|b| > 6
This will be true for values of b that are greater than 6 and values of b that are less than -6, due to the absolute value operator. Therefore the compound inequality that represents this situation is:
b< -6 or b > 6
Answer:
I think it is D (and)
Step-by-step explanation:
"Or" means that the b value can be less than -6 or greater than 6
so it could satisfy either one
so if you plug in a value that satifies one of the inequalities (ex: -7)
|-7|>6 and it works!
