Step-by-step explanation:
it is a 1:3 scale
3x = 27 + 3y
3x - 10y = 27
please explain how you got the answer.
Answer:
Hi there!
Your answer is:
Y= 0
X= 9
Step-by-step explanation:
3x=27+3y
3x-10y=27
Solve one of them for Y
I chose the first equation
3x=27+3y
-27
3x-27=3y
/3
x-9 = y
NOW, plug y in the second equation!
3x-10y=27
y= x-9
3x-10y=27
3x-10(x-9) = 27
Solve for x!
3x-10x+90 = 27
-7x + 90 =27
-90
-7x = -63
/-7
x= 9
FINALLY, plug back in x for y equation
y=x-9
x=9
y=9-9
y=0

A corporation earned a profit of $2.5 × 104 for 1 × 103 days in a row. What was the corporation’s total profit during this time period?
Answer:
26780
Step-by-step explanation:
First, let us find how much did the corporation earn in one day.
$2.5x104=260
Now that we have found the amount of money the corporation earned in a day, it is time to find how many days did the streak continue.
1x103=103
Finally, let us find how much they earned during that period.
260x103
Total profit of corporation during a time period of 103 days is $ 26780
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Profit earned by Corporation in a day = $ 2.5 x 104
= $ 260
Total time period of Corporations' profit = 1 x 103 days
= 103 days
Total profit during a time period of 103 days =
Profit earned by Corporation in a day x 103 days
Total profit during a time period of 103 days = 260 x 103
= $ 26780
Hence , total profit of corporation is $ 26780

Wendy was traveling from Baltimore, MD to Cleveland, OH. For the first 2 3/4 hours of her trip, she drove an estimated 63 mph. For the second portion of her trip, which took her 3 1/2 hours, she drove at an estimated rate of 57 mph. Write an expression to model her distance and calculate how far she drove. You may use the distance formula d=r*t (distance = rate * time).
Answer: D = r*t + r*t 372 3/4 = (63 * 2 3/4) + (57 * 3 1/2)
OR
D1 + D2 = Total 173 1/4 + 199 1/2 = 372 3/4
D1 = r1 *t1 63 * 2 3/4 = 173 1/4
D2 = r2 * t2 57 * 3 1/2 = 199 1/2
Step-by-step explanation:
The trip is in two segments, so calculate the distance driven in each portion, then add the two distances together to get the total.
Another way to write the expression would be D = r*t + r*t
The total distance that Wendy drove to Cleveland will be 372.75 miles.
For the first 2 3/4 hours of her trip, she drove an estimated 63 mph. Then, the distance traveled will be:
= 63 × 2 3/4
= 173.25 miles.
For the second portion of her trip, which took her 3 1/2 hours, she drove at an estimated rate of 57 mph, the distance will be:
= 57 × 3 1/2
= 199.5 miles
The total distance traveled will then be:
= 173.25 miles + 199.5 miles
= 372.75 miles.

A number is randomly selected from the set {1, 2, 3, 4, 5, 6, 7, 8}. If the number chosen is greater than 3, what is the probability it is odd?
Answer:
Hello!
The probability that the number chosen is greater then 3 and odd is 2/8
There are 5 numbers greater then 3, and of those 5, five and seven are the only odd numbers. So that is 2/8
Step-by-step explanation:
There are 5 numbers greater then 3, and of those 5, five and seven are the only odd numbers. So that is 2/8
If you are only talking about the numbers that are actually greater then 3 as your population, it is 2/5 :)
(I would appreciate Brainliest, please and thanks)
If a number randomly chosen is greater than 3, the probability that the number is odd is 2/5
How to determine the probability?The set of numbers is given as:
Set = {1, 2, 3, 4, 5, 6, 7, 8}.
The numbers greater than 3 are:
G3 = {4, 5, 6, 7, 8}
The odd numbers greater than 3 are
OG3 = {5, 7}
The required probability is then calculated using:
P = n(OG3)/n(G3)
This gives
P = 2/5
Hence, the probability is 2/5

William travels only on Saturdays and Sundays and has flown 1,020 miles this month. Jason travels every weekday and has flown 2,200 miles this month. If each man travels about the same number of miles each day, who travels more miles per day for this month? Explain.
Answer:
William
Step-by-step explanation:
There are 8 Saturday and Sunday in a month. William travels only on Saturdays and Sundays and has flown 1,020 miles this month. He has travelled (1020/8) miles per day = 127.5 miles/day
There are 30-8 = 22 weekdays in a month. Jason travels every weekday and has flown 2,200 miles this month. It would mean that he travelled (2200/22) = 100 miles/day.
It is very clear that no of miles travelled per day by William is more than the no of miles travelled per day by Jason for this month.

Joseph is making kebabs.he wants each kebab to have 3 pieces of meat and 4 pieces of vegetables.Which of the following could Joseph use to make kebabs without any leftovers?
Answer: Joseph could use C), D), and E) to make kebabs without any leftovers:
C) 30 pieces of meat and 40 pieces of vegetables
D) 45 pieces of meat and 60 pieces of vegetables
E) 72 pieces of meat and 96 pieces of vegetables
How were the answers determined? To solve for the answer, here are some pointers:
Consider the given which states that each kebab has 3 pieces of meat and 4 pieces of vegetables, and Joseph wanted to make kebabs without any leftovers - meaning, there should be no extra piece of meat or no extra piece of vegetable.
In choosing which is the answer, make sure that the number of pieces of meat must be divisible by 3 (pieces of meat), and the number of pieces of vegetables must be divisible by 4 (pieces of vegetables). This was also based on the given.
Moreover, the quotient for meat and the quotient for vegetables must be equal to each other so that there will be no leftovers.
Therefore, the answers are C), D), and E) because these three answers satisfy the conditions abo

A certain standardized test measures students’ knowledge in math and English. The scatterplot displays the scores for 10 randomly selected students.
The equation y = 54.16 + 0.87x is called the least-squares regression line because it:
is least able to make accurate predictions for the data.
makes the sum of the squared residuals as large as possible.
makes the sum of the squared residuals as small as possible.
causes the relationship between English scores and math scores to be strongest.
Answer:
it's C
Step-by-step explanation:
The correct answer is: The equation y = 54.16 + 0.87x is called the least-squares regression line because it makes the sum of the squared residuals as small as possible.
The least-squares regression line is a line that best fits the given data points by minimizing the sum of the squared residuals. Residuals are the vertical distances between the actual data points and the predicted values on the regression line. By minimizing the sum of the squared residuals, the line is able to provide the best overall fit to the data.
Therefore, the least-squares regression line aims to minimize the differences between the predicted values and the actual data points, making the sum of the squared residuals as small as possible.
