Answer:
1. She would have 67.5 dollars
2. 23 weeks
3. 11.25/week
4. 3:2
Step-by-step explanation:
1. 45/4 = 11.25. 11.25 x 6 = 67.5
2. 250/11.25 = 22.22 (rounding up would be 23 weeks)
3. 11.25/week
4. 3:2 (just flip the ratio around)
sorry if some are incorrect
Answer:
$67.50
Step-by-step explanation:
What you do is you divide $45 by 4, which is 11.25, which you then mutiply by 6, which equals 67.5
You have $11 and earn $0.50 for each cup of orange juice you sell. Write an equation in two variables that represents the total amount A (in dollars) you have after selling j cups of orange juice.
A= ??
Answer:
A = 0.50j
Step-by-step explanation:
Your total savings, A, are equal to the $0.50 you earn times the number of cups you sell, j.
Or, A = 0.50j.

Classify this triangle.
A triangle with two sides of equal length. The angle where these two sides meet is ninety degrees.
A. Acute scalene triangle
B.Obtuse isosceles triangle
C. Right isosceles triangle
D Right scalene triangle
A triangle with two sides of equal length and the angle where these two sides meet is 90° is Right isosceles triangle. Therefore, option C is the correct answer.
What is a right triangle?A right angled triangle is a triangle with one of the angles as 90 degrees. A 90-degree angle is called a right angle, and hence the triangle with a right angle is called a right triangle.
A right triangle with two equal-length legs is called an isosceles right triangle. The corresponding angles would also be congruent because the lengths of the two legs of the right triangle are equal. As a result, the two acute angles and two legs of an isosceles right triangle are congruent.
Therefore, option C is the correct answer.

There are 8 boys for every 3 girls at a concert. If there are 220 people at the concert, what is the difference between the total number of boys and girls at the concert?
Answer:
100
Step-by-step explanation:
First we get the ratio of 8:3 for the amount of boys to girls.
Assuming there are no other parts,
the Whole = A + B is the denominator:
Whole = 8 + 3 = 11
Part A = 8 and Part B = 3 are numerators for each fraction.
The fractions are then:
8/11 and 3/11
8/11 for boys
and 3/11 for the girls
Now we just multiply 220 by these fractions:
220 * 8/11 = 160
220 * 3/11 = 60
Then subtract:
160 - 60 = 100
Answer:
There are 60 girls and 160 boys

Summarize the numeric data by identifying the measures for the data distribution listed below.
1. Identify the mean and explain your solution process for each using detail and mathematical language.
2. Identify the median and explain your solution process for each using detail and mathematical language.
3. Identify the mode and explain your solution process for each using detail and mathematical language.
4. Identify the range and explain your solution process for each using detail and mathematical language.
Answer:
a.) For the Junior Varsity Team, mean would be the appropriate measure of center since the data is symmetric or well-proportioned while we should use standard deviation for getting the measure of spread since it also measures the center and how far the values are from the mean.
b.) For the Varsity Team, the median would be the appropriate measure of the center since the data is skewed left and not evenly distributed so median could be used since it does not account for outliers while we use IQR or interquartile range in measuring the spread of data since IQR does not account for the data that is skewed.

Select two ratios equivalent to the ratio of white socks to brown socks.
A) 35/32 B) 40/46 C) 36/33 D) 45/40
Answer:
D
Step-by-step explanation:
To find an equivalent ratio it must be multiplied or divided by the same number.
I multiplied 8 by 5 which got me 40
Then I multiplied 9 by 5 which got me 45
This means the equivalent ratio is 45/40

18x + 14y + 15 = 0
Answer:
y=-9/7x-15/14
Step-by-step explanation:
Slope-intercept form is y=mx+b
The y-coordinate is on one side, and the slope, x-coordinate, and y-intercept are on the other side.
18x+14y+15=0
-15 -15
18x+14y=-15
-18x -18x
14y=-15-18x
14y=-18x-15

1. Answer = About 1451.42 m³
First, we need to find the volume of the cube:Formula: πr²hVolume = π * 3² * 50 = 1413.72 m³Second, we need to find the volume of the cone:Formula: (πr²h)/3Volume = π * 3² * 4 = 37.69 m³Third, we need to add these two volumes to find the total volume of the figure.1413.72 m³ + 37.69 m³ = 1451.42 m³.2. Answer = 960 m³
Formula: (1/2(b*l)) * 20First, we need to find the area of the base (1/2 * b* l).1/2 * 8 * 12 = 48.Second, we need to multiply the area of the base by the height to get the volume.B * h = 48 * 20 = 960 m³.Use the information to answer the following question.
The bottom of a swimming pool is 10 feet below the surface of the water in the pool. The surface of the water is represented by the number 0, and the bottom of the pool is represented by the number -10. The pool’s diving board is the same distance above the surface of the water as the bottom of the pool is below the surface of the water.
What number represents the location of the diving board?
A.
20
B.
0
C.
10
D.
1/10
Answer:
C
Step-by-step explanation:
Since the difference between 0 and -10 is 10, this means that the difference between the diving board and the pool also has to be 10. Therefore, the diving board is 10 feet above the water since 0+10 is 10.

In the diagram, two parallel lines are intersected by a transversal.
What are the measurements of angles 1, 2, 4, 5, 6, 7, and 8?
Geometry
Short answer
Answer:
1=55°
2=125°
4=125°
5=125°
6=55°
7=125°
8=55°
Step-by-step explanation:
7= 125° because a line is 180°, so 55° + angle 7 = 180°, using simple algebra we can subtract 55 from both sides getting angle 7 = 125°
8= 55° because vertical angles are always congruent
4= 125° because all vertical angles are congruent
6= 55° because alternate interior angles are always congruent so angle 6 = 55°
1= 55° because vertical angles are always congruent
2=125° because alternate interior angles are always congruent so angle 2 = angle 7
5=125° because vertical angles are always congruent

A solid has volume 6 cubic units and surface area 22 square units. The solid is dilated, and the image has a volume of 48 cubic units. What is the surface area of the image?
What is dilation?
Dilation is the process of resizing or transforming an object. It is a transformation that makes the objects smaller or larger with the help of the given scale factor.
What is image?The new figure obtained after dilation is called image.
What is scale factor?Scale factor is the ratio of the sizes of the original figure with the dilated figure.
Scale factor formula[tex]scale factor = \frac{dimension of new shape }{dimension of original shape}[/tex]
According to the given question
Volume of solid = 6 cubic units
Surface area of solid = 22 square units
volume of image = 48 cubic units
therefore,
ratio of volumes = ratio of lengths
[tex]\frac{48}{6}[/tex] [tex]=8:1[/tex]
⇒ratio of sides = [tex]\sqrt[3]{8} :\sqrt[3]{1}[/tex]
⇒ ratio of sides = 2 : 1
Ratio of surface area of solid and image = square of ratio of sides = 4:1
⇒[tex]\frac{surface area of image }{surface area of solid} = \frac{4}{1}[/tex]
⇒[tex]\frac{surface area of image }{22} = \frac{4}{1}[/tex]
⇒ surface area of image = 4×21
⇒ surface area of image = 81square units.
