Middle School had 480 students. At the end of the
year, it had 504 students. What is the percent of
change in the enrollment?
explain.
Answer:
there is a 5% increase
Step-by-step explanation:
say 480=100%
4.8=1%
divide 504 by 4.8 you get 105,
so 504=105%
this is 5 more than 100 therefore 5%

Sixty-four is 66 2/3 percent of what number?
please answer quickly if you can
Answer:
n = 96
Step-by-step explanation:
[tex]66\frac{2}{3}[/tex] % = [tex]\frac{200}{3}[/tex] %
[tex]\frac{64}{n}[/tex] = [tex]\frac{\frac{200}{3} }{100}[/tex]
[tex]\frac{\frac{200}{3} }{100}[/tex] = [tex]\frac{2}{3}[/tex]
[tex]\frac{64}{n}[/tex] = [tex]\frac{2}{3}[/tex]
2n = 192 ⇒ n = 96

A company weighs 1,096 boxes of cereal and finds that 12.5% of them weighed less than one pound. Which of
the following is the number of boxes that weighed less than one pound?
Answer:
137 boxes
Step-by-step explanation:
1096 boxes * 0.125(12.5% of boxes weighing less than a pound) = 137 boxes
7. Make a box-and-whisker plot for the data. What is the upper quartile value?
56 32 48 52 51 53 48 38 35 42 40 46 54 50
In order to draw the Box-whisker plot, we need to rewrite the data in increasing order.
42 43 47 48 51 52 56 56 58 60 62 64 65 66
Mean of the data = (42 + 43 + 47 + 48 + 51 + 52 + 56 + 56 + 58 + 60 + 62 + 64
+ 65 + 66) ÷ 14
Mean of the data = 770 ÷ 14
Mean of the data = 55
Median = (56 + 56) ÷ 2
Median = 112 ÷ 2
Median = 56
Lowest value = 42
Highest value = 66
Range = Highest value - Highest value
Range = 66 - 42
Range = 24
Lower Quartile = 25% of the data
Lower Quartile = 48
Upper Quartile = 75% of the data
Upper Quartile = 62
Mal works at a photo gallery. He charges $50 for a large photo and $40 for a large frame. Sales tax is 5%.
How much total tax will a customer pay on both?
Answer the questions to show how to write and simplify expressions that represent the problem.
Answer:
The total amount that the consumer had to pay for both products was $ 94.50.
Step-by-step explanation:
Given that Mal sold a large photo for $ 50 and a large frame for $ 40, and that the sales tax for these products is 5%, to determine the total amount that the consumer had to pay to purchase these products arises from the following calculation:
(50 + 40) x 1.05 = X
90 x 1.05 = X
94.5 = X
Therefore, the total amount that the consumer had to pay for both products was $ 94.50.
Answer:
1. Evaluate the expression: $4.50
2. Expand the expression: 2.5 + 2 = 4.5 (4.50)
3. Total tax is 4.50. yes, both the evaluating and expanding got me the same answer.
4. Expanded Expression
Step-by-step explanation:
1. 0.05(50 + 40) evaluated is 4.50
2. I broke apart 4.50 into different numbers and got 2.5 + 2
3. pretty self explanatory

In the triangles, Line segment G K is-congruent-to line segment P N and Line segment G H is-congruent-to line segment M P.
Triangles G H K and P M N are shown. The length of side H K is 32 centimeters. The length of side M N is 40 centimeters. The lengths of sides H G and M P are congruent. The lengths of sides G K and P N are congruent.
Which statement correctly compares the angles?
Angle G is congruent to angle P.
Angle G is smaller than angle P.
Angle G is larger than angle P.
Angle G is congruent to angle N.
Answer:
B). Angle G is smaller than Angle P
Step-by-step explanation:
Given that,
GK ≅ PN,
GH ≅ MP
HK = 32 cm
MN = 40cm
and the other lengths are congruent.
This suggests that although the triangles are congruent yet they are not similar. Hence, the second statement correctly compares the angles that 'angle P is greater than angle G.'

pls help find the amount at the end of 6 hours
Answer:
A. 7,348
Step-by-step explanation:
P = le^kt
intitial population = 500
time = 4 hrs
end population = 3,000
So we have all these variables and we need to solve for what the end population will be if we change the time to 6 hours. First, we need to find the rate of the growth(k) so we can plug it back in. The given formula shows a exponencial growth formula. (A = Pe^rt) A is end amount, P is start amount, e is a constant that you can probably find on your graphing calculator, r is the rate, and t is time.
A = Pe^rt
3,000 = 500e^r4
now we can solve for r
divide both sides by 500
6 = e^r4
now because the variable is in the exponent, we have to use a log
[tex]log_{e}(6) = 4r[/tex]
ln(6) = 4r
we can plug the log into a calculator to get
1.79 = 4r
divide both sides by 4
r = .448
now lets plug it back in
A = 500e^(.448)(6 hrs)
A = 7351.12
This is closest to answer A. 7,348

Find the probability that when four numbers from 1 to 100, inclusive, are picked at random with no repetitions allowed, either all are odd, all are divisible by 3, or all are divisible by 5.
Answer:
The probability is;
0.076
Step-by-step explanation:
The count of numbers from 1 to 100 is 100
Let’s find the number of odd numbers
We can use;
a + (n-1)d = T
a is 1, d is 2 and T is 99
Thus;
1 + 2(n-1) = 99
n-1 = (99-1)/2
n-1 = 59
n = 50
So there are 50 odd numbers
Probability of selecting an odd number is 50/100 = 1/2
If all 4 are odd, we have 1/2^4 = 1/16
Let’s get the multiples of 3
we can use
a + (n-1)d = T
a = 3, n = ? , d = 3 and T = 99
So;
3 + 3(n-1) = 99
n-1 = 34
n = 33
So the probability is 33/100
All 4 are divisible will give 33/100^4
Multiples of 5
a + (n-1)d = T
a = 5, n = ? , d = 5 T = 100
5 + (n-1)5 = 100
5(n-1) = 95
n-1 = 19
n = 20
Probability is 20/100 = 1/5
All
four are multiples of 5
1/5^4 = 1/625
So the probability is;
1/16 + 1/625 + 0.01185921
= 0.0625 + 0.0016 + 0.01185921 = 0.07595921
I need help solving for X
The answer choices are
-9
10
-11
9
Answer:
x = -11
Step-by-step explanation:
Equations
The image shows a right triangle with angles 70°, 90°, and x+31.
The sum of the internal angles of a triangle is 180°, thus:
70 + 90 + x + 31 = 180
Simplifying:
191 + x = 180
Subtracting 191:
x = 180 - 191
x = -11

5 years ago, Cheryl was d years old, Brandon is 2 years older than Cheryl.
a. how old is Cheryl
b. how old is Brandon
c. what was the difference in their ages 5 years ago?
d. what is the sum of their ages now?
e. what will the sum of their ages be two years from now?
f. what will the difference of their ages be two years from now
will mark the brainliest.
Answer: See explanation
Step-by-step explanation:
a. how old is Cheryl?
Cheryl's age = d + 5
b. how old is Brandon?
d + 5 + 2
= d + 7
c. what was the difference in their ages 5 years ago?
Cheryl age five years ago = d
Brandon's age five years ago = d + 2
Difference = d + 2 - d = 2 years
d. what is the sum of their ages now?
Cheryl's age = d + 5
Brandon age = d + 7
Sum = d + 5 + d + 7
= 2d + 12
e. what will the sum of their ages be two years from now?
Two years from now,
Cheryl's age = d + 5 + 2 = d + 7
Brandon age = d + 7 + 2 = d + 9
Sum = d + 7 + d + 9
= 2d + 16
f. what will the difference of their ages be two years from now
Two years from now,
Cheryl's age = d + 5 + 2 = d + 7
Brandon age = d + 7 + 2 = d + 9
Difference = Brandon age - Cheryl age
= (d + 9) - (d + 7)
= 2 years.
