Answer:
The custodian will be able to repaint 7 bookcases with the amount of paint.
Step-by-step explanation:
The custodian has 5 1/4 gallons of paint, to find the number of bookcases the custodian will be able to repaint with this amount of paint if each bookcase requires 3/4 gallons, then we will simply divide 5 1/4 by 3/4 to give us the number.
But first we need to change 5 1/4 to improper fraction,
thus; 5 1/4 =
5 1/4 ÷3/4 = ÷
(We will want to change the division sign to multiplication, to do that, we will have to take the inverse of 3/4 which is 4/3 hence;
= ×
4 will cancel out 4 hence;
=
= 7
Therefore the custodian will be able to repaint 7 bookcases with the amount of paint.
Claire flips a coin 4 times. Using the table, what is the probability that the coin will show tails at least once?
A 2-column table with 5 rows. Column 1 is labeled number of tails with entries 0, 1, 2, 3, 4. Column 2 is labeled probability with entries 0. 06, 0. 25, question mark, 0. 25, 0. 6.
0. 06
0. 25
0. 69
0. 94
Answer: 0.94
Step-by-step explanation:
The required probability of getting at least one tail is given as 0.94. Option D is correct.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
The probability of getting tails at least one time is given as,
P(T) = 1 - P(T)'
From the given table.
P(T) = 1 - 0.06
P(T) = 0.94
Thus, the required probability of getting at least one tail is given as 0.94. Option D is correct.

What is an equation of the line that passes through the points (-1, 4) and (1, -6)?
Answer: y=-5x-1
Step-by-step explanation:
The two given points are (-1,4) and (1.-6)
We can then use the slope formula (Y2-Y1)/(X2-X1) to find the slope
4-(-6)/ -1-1 = 10/-2 = -5
Slope is -5
We then plug the slope in a set of points to find the y intercept
-5*-1+x = 4
5+x=4
x=-1
Then just add these two together to form the equation of y=mx+b
y=-5x-1
You're planning to place an order from an online boutique. Leggings cost $12 each and shipping is a flat rate of $5. If your total was $41, how many pairs of leggings did you buy?
The pairs of legging purchased is 3
How to determine the number of leggings?Let the number of leggings be x.
The cost per legging is given as:
$12
So, the total amount is:
Total = 12x
The flat rate is given as:
Flat rate = 5
So, we have:
Total = 12x + 5
Your total is $41
So, we have:
12x + 5 = 41
Subtract 5 from both sides
12x = 36
Divide through by 12
x = 3
Hence, the pairs of legging purchased is 3

While running for class president, Amanda handed out a campaign button. The catalog from which the button was ordered states that it has a circumference of 12.56 inches. What is the button's area?
Answer:
A = 12.554 square inches
Step-by-step explanation:
Let's start with the formulas:
Circumference = [tex]2\pi r[/tex]; Area = [tex]\pi r^{2}[/tex]
We can use the circumference to find the radius, r, which we need for the area
12.56 = [tex]2\pi r[/tex]
Isolating r gives us [tex]\frac{12.56}{2\pi } = r[/tex]
A = [tex]\pi (\frac{12.56}{2\pi })^{2}[/tex]
Solving gives us 12.554, which you can further round if necessary.

Find the area of this figure. Round your
answer to the nearest hundredth. Use
3.14 to approximate a.
A = [ ? ] ft?
Notice that only half of the circle is included in the figure!
The figure contains a triangle and a semicircle
The area of the figure is 49.12 square feet
How to determine the areaThe dimension of the triangle is:
Base = 8 ft
Height = 6ft
So, the area is:
Area = 0.5 * Base * Height
This gives
Area = 0.5 * 8ft * 6ft
Evaluate
Area = 24 square feet
The radius of the semicircle is:
r = 4 ft.
So, the area is:
[tex]Area = 0.5\pi r^2[/tex]
This gives:
Area = 0.5*3.14 * 4^2
Area = 25.12 square feet
Add the calculated areas.
Total = 24 square feet + 25.12 square feet
Total = 49.12 square feet
Hence, the area of the figure is 49.12 square feet

We know that:

This means that:
[tex]1. \space\ r + s + t = 180 + 180 + 180 - (180)[/tex]
Let's simplify the equation to find r + s + t.
Simplifying the equation:
[tex]r + s + t = 180 + 180 + 180 - (180) \\ \\ r + s + t = 180 + 180 + 180 - 180 \\ \\ r + s + t = 180 + 180 \\ \\ r + s + t = 360[/tex]
Thus, the sum of r, s and t is 360°

Dan buys a car for £2700.
It depreciates at a rate of 1.4% per year.
How much will it be worth in 5 years?
Answer:
The car will be worth £2516.22 in 5 years
Step-by-step explanation:
The rule of depreciating is
[tex]A=P(1-r)^{t}[/tex], where
A is the new valueP is the original valuer is the rate in decimalt is the time in years∵ Dan buys a car for £2700
∴ P = 2700
∵ It depreciates at a rate of 1.4% per year
∴ r = 1.4% = 1.4/100 = 0.014
∵ We need to find how much it will be worth in 5 years
∴ t = 5
→ Substitute all of these values in the rule above to find A
∵ [tex]A=2700(1-0.014)^{5}[/tex]
→ Use your calculator to find the answer
∴ A = 2516.22
∴ The car will be worth £2516.22 in 5 years
At an arcade, there is a machine that accepts game tokens and returns tickets
that can be redeemed for prizes. Inserting 5 tokens returns 3 tickets and
inserting 10 tokens returns 8 tickets. You must insert tokens in multiples of 5 or
10, and you have a total of 20 tokens. Identify the domain in this situation?
*
Answer: 5, 10, 15, 20
Step-by-step explanation:
Domain is all possible values that can be used as inputs in a function.
The arcade machine accepts multiples of 5 game tokens. You have 20 tokens. As the machine accepts 5 game tokens, the minimum is 5. Since you have 20, the maximum is 20.
The multiples of 5 are:
5 x 1 = 5
5 x 2 = 10
5 x 3 = 15
5 x 4 = 20
