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

What ratio is equivalent to 5 to 4
Natalia earns a base salary of $210 each week as a waitress. She usually makes an additional 15% in tips on all orders. Natalia has set a goal to make $1,000 each week. What inequality can she use to calculate x , the total dollar amount of orders needed for her to meet her goal?
Answer:
The inequality that she can use to calculate x, the total dollar amount of orders needed for her to meet her goal is: 210+0.15x≥1,000.
Step-by-step explanation:
The amount that Natalie makes each week is the result of adding up the base salary she earns plus the result of multiplying the dollar amount of orders for 15% and this result should be greater than or equal to $1,000, which would be:
210+0.15x≥1,000
Now, you can solve for x:
x≥(1,000-210)/0.15
x≥5,267
According to this, the answer is that the inequality that she can use to calculate x, the total dollar amount of orders needed for her to meet her goal is: 210+0.15x≥1,000.
You and some friends go to a book fair where booths are set out in rows. You
buy drinks at the refreshment stand and then walk 8 rows north and 2 rows
east to the science fiction booth. Then you walk 1 row south and 2 rows west
to the children's book booth. Where is the children's book booth in relation to
the refreshment stand?
Answer:
7 rows north of refreshment stand
Step-by-step explanation:
8 rows north and then 2 rows east followed by 1 row south and then 2 rows west will put you directly north of the refreshment stand but since you have traveled one row south, it will be 8-1 = 7 rows north of the refreshment stand

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.

Mr. R's kindergarten class has 22 students. There are 2 more girls than boys in his class. How many boys are there?
let x=
let y=
Answer:
13
Step-by-step explanation:
If we want to find out if there are an equal amount of boys and girls, then we do 22/2 which is 11. BUT, it says there are two more girls than boys. So...
11+2 since there are two more boys than girls. 11+2=13 girls.
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).

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).

If 50 teenagers like sandwiches, what is the total number of teenagers that Jane surveyed? Show your work. (4 points) Part C: Give an example of a situation in which a percentage is greater than 100%. (2 points)
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
