Answer:
B.
Step-by-step explanation:
Since the main goal for Marco is to stay under his budget which is 279, it's expected that he would want to spend less than or equal to his budget and that is the point to spend less than our goal of spending limit. If the cost of uniform and the cost of each of his classes are less than how much money he wants to spend, than that is going to still be within his budget even if the equation equals to 279 it is still within his budget anything greater would be consider over spending past his budget. Therefore making all other equations false.

Answer:
The mean age of the frequency distribution for the ages of the residents of a town is 43 years.
Step-by-step explanation:
We are given with the following frequency distribution below;
Age Frequency (f) X
0 - 9 30 4.5 135
10 - 19 32 14.5 464
20 - 29 12 24.5 294
30 - 39 20 34.5 690
40 - 49 25 44.5 1112.5
50 - 59 53 54.5 2888.5
60 - 69 49 64.5 3160.5
70 - 79 13 74.5 968.5
80 - 89 8 84.5 676
Total 242 10389
Now, the mean of the frequency distribution is given by the following formula;
Mean =
= = 42.9 ≈ 43 approx.
Hence, the mean age of the frequency distribution for the ages of the residents of a town is 43 years

Please help! Will give 10 points and brainliest to first...only need 2,4,6,8
Answer:
Step-by-step explanation:
2: 1:4 scale factor
4: 4/5 = x/15. 5x=60. x is 12
6: it's a 2:7 ratio. so x would be 8 and y would be 35
8... it's a 4:7 ratio, as both 52 and 91 are divisible by 13 so there's the scale factor

Barbara, Becky and Beth dressed up as princesses for
Halloween. One was Snow White. One was Sleeping
Beauty. One was Cinderella. Becky is not Sleeping
Beauty and she went trick-or-treating with Snow White.
Beth and Sleeping Beauty are sisters. Who is Snow
White?
Answer:
The answer is Beth.
Step-by-step explanation:
It states "Becky is not Sleeping Beauty and went trick-or-treating with Snow White" so we know that its not Becky. It also states "Beth and Sleeping Beauty are sisters" so we know that Beth is not Sleeping Beauty and we know that Becky is not Sleeping Beauty or Snow White. So it means that Barbara is Sleeping Beauty, Becky is Cinderella and Beth is Snow White.

Write the point-slope form of the line that passes through (-8, 2) and is perpendicular to a line with a slope of -8. Include all of your work in your final answer. Type your answer in the box provided to submit your solution.
Answer:
y - 2 = 1/8(x+8)
Step-by-step explanation:
The slope of lines that are perpendicular are each other's opposite reciprocal.
so, the reciprocal of -8 = -1/8, then find the opposite of -1/8 which is 1/8.
Point-slope form : y - y1 = m(x - x1)
(x1,y1) = (-8,2)
so, y - 2 = 1/8(x+8) is our final answer!
Aline crosses the coordinates (-4,4) and (2.-5). What is the slope
of the line?
Answer:
Step-by-step explanation:
Use the slope formula:
[tex]m = \frac{y2 -y1}{x2 - x1}[/tex]
where m = slope
Given the coordinates
(-4, 4) ---> this means x1 = -4 , y1 = 4
(2, -5) ---> this means x2 = 2 , y2 = -5
Substitute these values into the slope formula:
[tex]m = \frac{y2 -y1}{x2 - x1}[/tex]
[tex]m = \frac{-5 -4}{2 - (-4)} = \frac{-9}{2+4} = \frac{-9}{6} = \frac{-3}{2}[/tex]
The slope of the line passing through the coordinates (-4, 4) and (2, -5) is - 3/2.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
The slope of the line passing coordinates (-4, 4) and (2, -5) can be obtained as we know slope is rise over run which is slope(m) = (y₂ - y₁)/(x₂ - x₁) = (-5 - 4)/(2 + 4) = -9/6 = - 3/2.

In the garden, there were 15 red flowers, 5 blue flowers and 2 yellow flowers. What percent of the flowers were red?
Answer:
68.2
Hope this helps. :)
Answer:
I believe it would be 65?
Step-by-step explanation:
if if I divide 22 by 100 I will get 2.2.
And at 5 + 2 that means if you combine the blue flowers and yellow flowers you will get $7 in total.
And there's 15 red flowers 7 is kind 40 of 15 which is 100 because. 8+7=15 .
And for 15 to be completely split in half it would have to be 7.5.
But that's not how it works so if we put 8 & 7 into percents 8 would be 65 and 7 would be 35

7. Carlos is renovating a house and hires a plumber to install the piping for 4 points
the new bathroom. The plumber charges an initial fee plus an hourly rate
for the number of hours it will take to complete the installation. The
function y = 100 + 35x can be used to model the total cost of the job, in
dollars. What does the slope in the expression of this function represent? *
the initial fee for the installation, $35
the initial fee for the installation, $100
the cost per hour of installation work, $35
the number of hours to complete the installation, x
Answer:
the cost per hour of installation work, $35
Step-by-step explanation:
y = 35x + 100
the slope of a function is the coefficient of x, therefore, it is 35. $100 is the initial fee, since it ia the y intercept, and $35 is the cost per hour. y is the total amount, and x is the number of hours. Therefore, the only possible answer is the third choice,

Stefan estimates the income and expenses for renting
a phone accessory store in the mall. He enters the
amounts in the table below. Should Stefan
rent a phone accessory store? Explain.
Answer/Step-by-step explanation:
If total income is more than total expenses, she should rent it. If the total income is less than the total expenses, she should not rent it.
Total income estimated in a month:
Sales: $950 per week = 950*4weeks = $3,800 per month
Services: $2,875 per month
Total estimated income per month = $(3,800 + 2,875) = $6,675
Total expenses estimated in a month:
Rent: $4,500 per month
Travel: $7.5 per day = 7.5*7days = $52.5 per week.
Assuming there are 4 weeks in a month, expenses for travel in a month will be:
$52.5*4 = $210
Merchandise: $1,650 per month
Total expenses estimated per month = $(4,500 + 210 + 1,650) = $6,360
Total estimated income ( > total estimated expenses in a month, therefore, Stefan should rent the phone accessory store. She will make profit.

A township is a U.S. land measurement of about 36 square miles. About how many square miles are in 2 1/2 township
Answer: 90 sqm
Step-by-step explanation:
The township's land measurement is 36 square miles. If you want to know the measurement in 2 1/2 townships you need to multiply 2 1/2 times the square miles in a single township.
Step 1: Convert 2 1/2 to an improper fraction.
2 1/2 = 5/2
Step 2: Multiply
5/2 x 36/1 = 180/2 = 90 sqm
