Answer:
Step-by-step explanation:
We can solve this easily with proportions. If the tank is 20% full and has 500 gallons in it, when it is 100% full, it will have a proportional amount of water in it:
[tex]\frac{20}{500}=\frac{100}{x}[/tex] where the percentages are on the top and the number of gallons is on the bottom of those ratios.
Cross multiply to solve for x:
20x = 50000 so
x = 2500 gallons, max capacity

A team won 5 and lost 2 of their first 7 games. The
team continued to win at this rate and won w
games in the 28-game season. Which of the
following proportions could be used to determine w?
Answer:
5/7=W/28
Step-by-step explanation
They won 5 out of 7 played games so that's their win rate. If the same team continued to do this for 28 games then they would win 20 times.
Sharon wants to put lace around the edge of the circular mirror shown.
12 in.
C = TD, where C is the circumference, and D is the diameter. Use 3.14 for the value of .
How many inches of lace will Sharon need to cover the edge of the mirror exactly once?
A. 3.82 in.
B. 18.84 in.
C. 37.68 in.
D. 75.36 in.
Answer:
37.68in
Step-by-step explanation:
Circumference = πd
d is the diameter = 12in
To get the number of lace that will cover we will find the circumference
C = 12 * 3.14
C = 37.68in
Hence the amount of lace needed is 37.68in

Answer:
x=-2 y=7
Step-by-step explanation:
Multiple -5 for the second equation to get -5x-20y=-130. Adding -5x-20y=-130 to 5x+y=-3 should get you -19y=-133. Divide both sides by -19 to get y=7. Subsitute 7 in for y for the first equation. Subtract 7 on both sides to get 5x=-10. Divide both sides by 5 to get x=-2. So, x=-2 and y=7.
Evaluating probability: A particular type of mouse's weights are normally distributed, with a mean of 726 grams and a standard deviation of 23 grams. If you pick one mouse at random, find the following: (round all probabilities to four decimal places) a) What is the probability that the mouse weighs less than 722 grams
Answer:
0.4325 = 43.25% probability that the mouse weighs less than 722 grams
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 726 grams and a standard deviation of 23 grams.
This means that [tex]\mu = 726, \sigma = 23[/tex]
a) What is the probability that the mouse weighs less than 722 grams
This is the p-value of Z when X = 722. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{722 - 726}{23}[/tex]
[tex]Z = -0.17[/tex]
[tex]Z = -0.17[/tex] has a p-value of 0.4325
0.4325 = 43.25% probability that the mouse weighs less than 722 grams

Answer:
s = 4π Exact answer
s = 12.56 Decimal approximation
Step-by-step explanation:
cicrumference = πd

s = 4π Exact answer
s = 4 * 3.14
s = 12.56 Decimal approximation
Students in an Algebra 1 class will perform the following experiment and then model it mathematically. They begin with 128 two-colored counters (a chip that has a yellow side and a red side) in a bag and complete the following steps:
Pour the counters from the bag onto the floor.
Count the number of counters that land on yellow.
Record the trial number and the number of counters that landed on yellow.
Put the counters that landed on yellow back into the bag and leave the rest on the floor (off to the side).
Steps 1 to 4 constitute one trial of the experiment. Repeat trials until no counters land on yellow.
Question 1
POSSIBLE POINTS: 1
Part A
Select the equation that best represents f(n), the number of yellow counters that land on yellow (and are put back into the bag) at the end of trial n, when n≥1?
A f(n)=128(12)nf of n is equal to 128 times 1 half to the n th power
B f(n)=128−12nf of n is equal to 128 minus 1 half n
Question 2
Part B
How many trials would the students most likely need to run until exactly one counter lands yellow side up (and is put into the bag)? Use mathematics to justify your response.
The number of counters is an illustration of a linear function
The number of counters that land on yellow is: [tex]f(n) = 128 - \frac 12n\\[/tex]The students need 254 trials to have one yellow side upHow to determine the equation
The number of counters is given as:
Count = 128
Each counter is two-colored (i.e. 1/2 yellow and 1/2 red)
So, the equation that represents the number of counters that land on yellow is:
[tex]f(n) = 128 - \frac 12n\\[/tex]
The number of trials to have one yellow side upWhen one yellow side is up, we have:
f(n) = 1
So, we have:
[tex]1 = 128 - \frac 12*n[/tex]
Subtract 128 from both sides
[tex]-127 = - \frac 12*n[/tex]
Multiply both sides by -2
[tex]n =254[/tex]
Hence, the student needs 254 trials to have one yellow side up

Your local dry cleaners is running a special. The dry cleaner is offering a 13% discount for any drop off that is over $40. Also, they are running a neighborhood special of an additional 5% off. Given this information, determine the decay factor corresponding to each percent decrease.
a.
34.8; 33.06
c.
0.87; 0.95
b.
0.384; 0.3306
d.
87; 95
Answer:
a. 34.8; 33.06
Step-by-step explanation:
The computation is shown below;
since in the question it is mentioned that that if the price is $40 so if offered the 13% discount
So the 13% discount on $40 is
= $40 - 13% of $40
= $34.80
Now additional 5% is also provided
So,
= $34.80 - 5% of $34.80
= $33.06
Therefore the first option is correct

How many sides do 2 octagons, 4 pentagons, and 5 triangles have in all?
Answer: 51
Step-by-step explanation:
2 octagons have 16 sides because an octagon has eight sides. So, 8x2=16.
4 pentagons have 20 sides because a pentagon has 5 sides. So, 4x5=20.
5 triangles have 15 sides because a triangle has 3 sides. So, 5x3=15.
In all, 16+20+15= 51
What is0.54¯¯¯¯ expressed as a fraction in simplest form?
Enter your answer in the box.
Answer:
0.54 as a fraction is 54/100 and simplified it would be 27/50
Answer:
27 / 50
Step-by-step explanation:
You can find this out by re-stating it as 54 / 100 and removing common factors between the numerator and denominator. In this case, only the number 2 can be factored out:
54 / 100
= 27 / 50
27 is a perfect cube (three cubed), and 50 is not divisible by 3, so we can't factor it further.

Find a polynomial f(x) of degree 5 that has the following zeros. 1, 8, -7, 5, -4. Leave your answer in factored form
Answer:
f(x) = (x-1) (x-8) (x +7)(x-5) ( x+4)
Step-by-step explanation:
The zeros of the function are written in the form
f(x) = (x-a)(x-b)..... where the a,b are the zeros
f(x) = (x-1) (x-8) (x - -7)(x-5) ( x--4)
Rewriting
f(x) = (x-1) (x-8) (x +7)(x-5) ( x+4)
x = 12 − y
2x + 3y = 29

A watercolor painting is 25 inches long by 12 inches wide. Ramon makes a border around the watercolor painting by making a mat that adds 3 inches to each side of the length and the width. What is the area of the mat?
Answer:
the area of the mat = total area added minus the original area of the water color painting.
Step-by-step explanation:
length of the mat is:L = 20 in + 1 in + 1 in because 1 in is added to each sideL = 22 inwidth of the mat is:w = 9 in + 1 in + 1inw = 11 in
Area mat = (22 in x 11 in) - ( 20 in x 9 in)
area mat = 62 sq in is the area of the mat
