The number of students who chose not to take French their freshman year is 147.
According to the question,
We have the following information:
72% of students chose to study French their freshman year.
Now, 72% of students is equal to 378.
Let's take the number of students to be x.
So, we have:
72x/100 = 378
72x = 378*100
x = (378*100)/72
x = 525
Now, we have to find the number of students who chose not to take French their freshman year:
(100%-72%)
28%
Now, we have to find the 28% of total number of students:
(28*525)/100
14700/100
147
Hence, the number of students who chose not to take French their freshman year is 147.

An item on sale costs 40% of the original price if the original price was $45 what is the sale price
Answer:
$18
Step-by-step explanation:
Finding 40% of something is the same as multiplying it by 0.4.
If we do this to 45 we get:
45 x 0.4 = 18
So, the sale price would be $18.

Slope =
Linear equation =
The y-intercept of the graph is: 3,000
The slope is: -2.75
The linear equation of the graph is: y = -2.75x + 3,000.
What is the Linear Equation of a Graph?The linear equation that represents a linear graph shows the slope (m) and y-intercept (b) of the graph and is expressed in slope-intercept form as, y = mx + b.
In the given graph:
The y-intercept (b) is the starting value, which is the point on the y-axis where the line intercepts, and it is equal to: 3,000.
Using two points on the graph, (0, 3,000) and (2, 2,450), the slope of the graph = change in y / change in x = (3,000 - 2,450)/(0 - 2) = 550/-2 = -2.75.
To write the linear equation, substitute m = -2.75 and b = 3,000 into y = mx + b:
y = -2.75x + 3,000.

Sarah left the house at 12:15 p.m. to go to the store. She spent $42.20 on 2 books for her children and she spent $5.67 on a toys for her dog, Rover. Sarah arrived home at 1:00 p.m. How much did Sarah spend on each book?
Answer:
$18.26
Step-by-step explanation:
The total price is $42.20
We want to know how much 1 of those books cost
We know that $5.67 were for her dog
So we are gonna subtract that from $42.20
$42.20-$5.67=36.53
Now your gonna divide that by 2 because she got 2 books
So 36.53/2=$18.26
1 book=$18.26

Circle A has center (0, 0) and radius 3. Circle B has center (-5, 0) and radius 1. What sequence of transformations could be used to show that Circle A is similar to Circle B?
A translation of T(x, y) = (- 5, 2) and a dilation with center (- 5, 2) with a scale factor of 1 / 3 are necessary to transform circle A into circle B. (Correct choice: D)
What sequence of rigid transformations can be done on a circle
In this problem we must determine the sequence of transformations require to transform circle A into circle B. From analytical geometry we know that the equation of the circle in standard form is:
(x - h)² + (y - k)² = r²
Where:
(h, k) - Coordinates of the center.r - Radius of the circle.Then, we need to apply the following rigid transformations:
Translation
f(x, y) → f(x - h, y - k), where (h, k) is the translation vector.
Dilation with center at the center of the circle
r → k · r, where k is the scale factor.
The circle A is represented by x² + y² = 3, then we derive the expression for the circle B:
f(x, y) → f(x + 5, y - 2)
(x + 5)² + (y - 2)² = 9
r → k · r
(x + 5)² + (y - 2)² = (1 / 3)² · 9
(x + 5)² + (y - 2)² = 1
Then, a translation of T(x, y) = (- 5, 2) and a dilation with center (- 5, 2) are necessary to transform circle A into circle B.

Suppose the Rocky Mountains have 72 centimeters of snow. Warmer weather is melting the snow at a rate of
5.8 centimeters a day. If the snow continues to melt at this rate, after seven days of warm weather, how much
snow will be left?
Answer:
31.4 cm
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Slope-intercept form of a linear equation}\\\\$y=mx+b$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}[/tex]
The y-intercept is the y-value when x is zero, so the initial value.
If the initial amount of snow is 72 cm, the y-intercept is 72.
The slope is the rate of change.
If the snow is melting at a rate of 5.8 cm per day, then the rate of change is -5.8.
Therefore, the equation that models the given word problem is:
[tex]\boxed{\begin{minipage}{5.4 cm}\phantom{w}\\$y=-5.8x+72$\\\\where:\\ \phantom{ww}$\bullet$ $y$ is height of the snow in cm. \\ \phantom{ww}$\bullet$ $x$ is the time in days.\\\end{minipage}}[/tex]
To find how much snow is left after 7 days, substitute x = 7 into the found equation:
[tex]\implies y=-5.8(7)+72[/tex]
[tex]\implies y=-40.6+72[/tex]
[tex]\implies y=31.4[/tex]
Therefore, there will be 31.4 cm of snow left after seven days of warm weather.

write the next three terms of the arithmetic sequence. 4, 3 3/4, 3 1/2, 3 1/4.
In an arithmetic sequence, the consecutive terms differ by a common difference. This means that the second term minus the first term would be equal to the third term minus the second term. The pattern continues.
Looking at the sequence, the common difference is
3 3/4 - 4 = 3 1/2 - 33/4 3 1/4 - 3 1/2 = - 1/4
The next term after 3 1/4 would be 3 1/4 + - 1/4 = 3 1/4 - 1/4 = 3
The next term after 3 would be 3 + -

What is the largest volume a sphere can have if it is covered by 6m2 of fabric?
The formula for determining the surface area of a sphere is expressed as
Surface area = 4 * pi * radius^2
From the information given,
surface area = 6
pi = 3.14
thus,
6 = 4 * 3.14 * radius^2
6 = 12.56radius^2
[tex]\begin{gathered} radius^2\text{ = }\frac{6}{12.56}=0.478 \\ \text{radius = }\sqrt[]{0.478} \\ \text{radius = 0.69} \end{gathered}[/tex]The formula for determining the volume of a sphere is expressed as
Volume = 4/3 * pi * radius^3
