Step-by-step explanation:
Step 1: Define inequality
7r + 8 > 64 - r
Step 2: Solve for r
Add r to both sides: 8r + 8 > 64Subtract 8 on both sides: 8r > 56Divide 8 on both sides: r > 7Here we see that any value r greater than 7 would work as a solution to the inequality.
A school is having a canned food drive. Each class is challenged to collect 220 cans. If there are x classes in the school, which equation could be used to find the total number of cans, y, the school will collect if each class meets the challenge?
A. y = 20x
B. y = 220x
C. y = 220/x
D. y = 220 + x
Answer:
B)
Step-by-step explanation:
no. of Classes = x
cans = 220
220×x = 220x
no.of classes × cans = total number of cans
Out of 90 candies, 30% are chocolate candies. How many candies are chocolate candies
Answer:
27 candies are chocolate candies.
Step-by-step explanation:
What we need to do is find 30% of 90, since this number will be the number of chocolate candies.
30% of 90 is basically 3/10 (30%) of 90:
(3/10) x 90 = 27
There are 27 chocolate candies.
Answer:
27
Step-by-step explanation:
it is as simple as 3*90÷10
Due to a late summer drought, the change in water level (in feet) in the pond behind Eastview is falling
every day. The Science Club made a graph of the water level over time.
They found the y-intercept to be (0,26). They determined the x-intercept to be (52,0).
Thoroughly explain the meaning of the x-intercept. (Use a full sentence that includes the values of that
intercept.)
Answer:
The x-intercept represents when the water level of the Eastview pond. This shows that the Eastview pond's water level reached 0 at 52 (days/years/hours/minutes... etc).

slope = undefined & x-intercept = -13
The linear equation with undefined slope and an x-intercept of -13 is:
x = -13
Which is the equation of the line with an undefined slope and x-intercept of -13?
The general linear equation is written as:
y = a*x + b
Where a is the slope and b is the intercept of the y-axis.
And undefined slope is used only for vertical lines, where the slope (technically) tends to infinite.
These lines are of the form x = K, where K is a real number. (so we have x = constant)
And we know that the x-intercept is at x equal -13, with that we can conclude that the constant will be equal to -13, then the equation of the line is:
x = -13.

If 50 teenagers like sandwiches, what is the total number of teenagers that Jane surveyed? Show your work.

Answer:
A. 190 Teenagers
B. 200 Teenagers
C. A situation where we can have percentage greater than 100 % is found during increase in growth of population
Step-by-step explanation:
Part A.
Mike surveyed 250 teenagers to find out their favorite food. He found that 76% of the teenagers surveyed like burgers. Part How many teenagers surveyed like burgers?
We were told from the question, 76% of the teenagers surveyed loved burgers.
Total number of teenagers = 250
Therefore, the number of teenagers surveyed that loved burgers =
76/100 × 250
= 190 teenagers
Part B: In another survey, Jane found that 25% of the total number of teenagers surveyed like sandwiches. If 50 teenagers like sandwiches, what is the total number of teenagers that Jane surveyed?
Let the total number of teenagers surveyed be represented by x
Therefore,
25% of x = 50 teenagers
25/100 × x = 50
25x/100 = 50
Cross Multiply
25x = 100 × 50
25x = 5000
x = 5000/25
x = 200
Therefore, 200 teenagers were surveyed
Part C: Give an example of a situation in which a percentage is greater than 100%. (2 points)
A situation where we can have percentage greater than 100 % is found during increase in growth of population

2. Aashvi is making garlic naan. The recipe calls for 2 cups of flour, but Aashvi only has teaspoons. If 24 teaspoons are equal to 1/2 cup, how many teaspoons will Aashvi use to measure 2 cups of flour? *
Answer:
98 teaspoons
Step-by-step explanation:
Aashvi is making garlic naan. The recipe calls for 2 cups of flour, but Aashvi only has teaspoons. If 24 teaspoons are equal to 1/2 cup, how many teaspoons will Aashvi use to measure 2 cups of flour? *
From the above question, we understand that:
1/2 cup of flour = 24 teaspoons
2 cups of flour = x teaspoons
Cross Multiply
1/2x = 24 × 2
x = 48 ÷ 1/2
x = 48 × 2
x = 98 tea spoons
Therefore, Aashvi will use 98 teaspoons to measure 2 cups of flour.

Function g(x) has a removable discontinuity at x = c, where g(c) is undefined. Which statement describes the one-sided limits at x = c?
Answer:
B
Step-by-step explanation:
The function that describes the one-sided limits at x = c.
[tex]\lim_{x \to c^-} g(x) = a\\\\ \lim_{x \to c^-} g(x) = a[/tex] ( for some value of a).
What is removable discontinuity?A discontinuity is removable if the limit of the function at the point of discontinuity exists and the value of the function exists but they aren't equal to each other.
We can remove that discontinuity by making the value of the function equate to the limiting value of the function at that point.
Function g(x) has a removable discontinuity at x = c,
where g(c) is undefined.
In this case, the statement that's is true for g(x) is that you can remove the discontinuity at x = c by defining g(c) = a.
The function that describes the one-sided limits at x = c.
[tex]\lim_{x \to c^-} g(x) = a\\\\ \lim_{x \to c^-} g(x) = a[/tex] ( for some value of a).

Your friend made $324 babysitting last year.This year she made 296% of what she made last year.How much more did your friend make this year?
Answer:
$635
Step-by-step explanation:
She made a total of $959 anad last year she made $324 so you then subtract the ammounts because the problem wants to know how much MORE she made.
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Required percentage value = a
total value = b
Percentage = a/b x 100
The more amount made this year is $635.04
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Your friend made $324 babysitting last year.
This year she made 296% of what she made last year.
This means,
The amount this year.
= 296/100 x 324
= $959.04
The difference in the amount.
= $959.04 - $324
= $635.04
The difference in the amount can also be calculated as,
= 296% - 100%
= 196% more this year.
So,
196% of $324
= 196/100 x 324
= $635.04
Thus,
The more amount made this year is $635.04
