Jonas and Marisol were the only candidates for sixth-grade class president. Jonas received 35 votes and Marisol received 75 votes.
Of the 75 votes cast for Marisol, 40% were girls. How many girls voted for Marisol?
****BRANLIEST OF 2
Answer:
30girls
Step-by-step explanation:
If out the 75 votes cast for Marisol, 40% were girls, the number of girls that votes for Marisol can be gotten by taking 40% of the total number of votes casted for Marisol as shown:
Number of girls = 40/100 × 75
Number of girls = 300/10
Number of girls that voted for Marisol = 30girls

The steps Quentin took to evaluate the expression 3m - 3+3 when m = 8
are shown below.
3m - 3 + 3 when m=8
3 x 8 = 24
24 - 3 =21
21 + 3 = 7
What should Quentin have done differently in order to evaluate the
expression?
divided (24-3) by (24x3)
divided (24-3) by (24-3)
subtracted (3 + 3) from 24
subtracted 3 from (24 +3)
Quentin had properly substituted m with 8, but he mistakenly added 3 to 21 rather than subtracting. The right final calculation should provide 24, not 7.
Explanation:In order to correctly evaluate the expression 3m - 3 + 3 when m = 8, Quentin starts off correctly by replacing m with 8, resulting in 24. The mistake happens when Quentin incorrectly adds 3 to 21 instead of subtracting 3 from 21. The correct sequence of steps should be:
3m - 3 + 3 when m=8Replace m with 8. Therefore, 3 * 8 = 24Subtract 3 from 24. Therefore, 24 - 3 = 21Add 3 back to the result of 21 - 3. Therefore, 21 + 3 = 24Learn more about Math Expression Error Correction here:

Determine the following for the transformed cosine function shown whose period is 1,080 degrees.
Frequency:
b in the equation:
Answer:
Frequency: 1/1080
b in the equation: 1/3
Step-by-step explanation:
The frequency is 1/1080 and the value of b is 1/3
How to determine the values of frequency and b?The period is given as;
T = 1080
The frequency is calculated using:
f = 1/T
So, we have:
f = 1/1080
The value of b is calculated using:
2π/b = T
This gives
2π/b = 1080
Make b the subject
b = 2π/1080
Express 2π as degrees
b = 360/1080
Divide
b = 1/3
Hence, the frequency is 1/1080 and the value of b is 1/3

A pyramid-shaped roof has a slant height of 16 ft and its square base is 40 ft wide. How much roofing material is needed to
cover the roof?
Answer:
1280ft²
Step-by-step explanation:
To find the total surface area of a square pyramid, we find the area of the square base and add it to the area of the four triangular faces.
The area of the square base is
[tex] {40}^{2} = 1600 {ft}^{2} [/tex]
The area of the four triangular faces is
[tex] = 4 \times \frac{1}{2} \times 40 \times 16 = 1280 {ft}^{2} [/tex]
In the context of this problem , the base will not be roofed, therefore the 1280 ft² of material is needed to cover the roof

Estimate the perimeter of the figure to the nearest whole number.
Answer:
See Explanation Below
Step-by-step explanation:
The question is incomplete (because the figure to calculate the perimeter is missing).
However from the comment attached to your question, I understand that the figure looks like a plus sign.
The perimeter of a plane shape is calculated by adding the length of each side of the shape.
Take for instance;
A square of length 5cm.
We know that a square has 4 equal sides; meaning that the length of the other sides are also 5cm
So, the perimeter of the square will be calculated as 5cm + 5cm + 5cm + 5cm = 20cm
Similarly, the perimeter of a triangle whose sides are 4ft, 3ft and 5ft will be calculated by adding up the length of the three sides.
Perimeter of the triangle = 4ft + 3ft + 5ft
Perimeter = 12ft.
Having explained how the perimeter of a plane shape is calculated; take for example, the attachment below.
(The sides are measured in centimetres)
The plus sign has 12 sides; Its perimeter is calculated by adding up the length of the 12 sides.
Perimeter = 3 + 7 + 7 + 5 + 5 + 5 + 5 + 2 + 2 + 4 + 4 + 3
Perimeter = 52cm

A windshield wiper blade turns through an angle of 135°. The bottom of the blade traces an arc with a 5-inch radius. The top of the blade traces an arc with a 22-inch radius. To the nearest inch, how much longer is the top arc than the bottom arc? Round to the nearest whole number.
The upper arc is longer than the lower arc by inches.
Step-by-step explanation:
Since both the arcs are made by the same wiper blade, hence the angle of the arc would be the same.
The radius of upper arc= 22 inch
The radius of the lower arc= 5 inch
Angle made by the arc= 135°
We know that length of the arc= (angle made/360)*2πr
Where r is the radius of the arc
The difference in the arc length has been due to the difference in radius of the arcs.
Hence, the difference in the radius would be equal to the difference in arc length.
Difference in wiper radius= 22-5= 17 inch
Putting the values together
arc length= (135/360)*2*3.14*17
arc length= 40.035
The difference in arc length=40 inches (rounded off to the nearest whole number)

How many inches if wooden sticks will be required?
The required amount of wooden sticks would depend on specific measurements for different projects, such as making a Biltmore stick for tree height measurement or spacing vertical studs 16 inches apart, which is equal to 40.64 centimeters. Measurements and conversions would be necessary to determine the exact amount of material needed.
Explanation:The amount of wooden sticks required would depend on the specific project being undertaken. The details provided mention various projects, including constructing a Biltmore stick for measuring tree heights, vertical studs spaced 16 inches apart for lumber usage, and spacing between scaffolds that could be anywhere from 3 to 12 inches. For the Biltmore stick, you would need a stick long enough to reach from your eye level to the ground, as well as additional sticks or markers for the grading. For constructing vertical studs spaced 16 inches apart, you would convert that distance into centimeters, where 16 inches is equal to about 40.64 centimeters. Other examples require sticks of varying sizes, from the barrel of a plastic stick pen cut in half, which would be a few inches, to a list of materials needed for a pyramid structure that changes by 12 inches per level.

Find the equation using the graph and table of values.
Answer:
[tex]y=-1x+1[/tex]
Step-by-step explanation:
To find the equation, you have to know the equation 'format' which is [tex]y=mx+b[/tex]
mx is the slope
b is the y-intercept
The slope is -1 because it goes down 1 and right 1 [tex]\frac{rise}{run}[/tex]
The y-intercept is 1 because that is where the line touches the y-axis.
So, if we plug it in, it will look like:
y = -1x + 1 which can also be written as y = -x + 1

What is the distance between (-6,4) and (-8, 6)?
Answer:
[tex]\sqrt{8}=2\sqrt{2}[/tex]
Step-by-step explanation:
by using well known formula, distance on XOY plane
[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\=\sqrt{(-8-(-6))^2+(6-4)^2}
\\=\sqrt{(-2)^2+(2)^2}[/tex]
The distance between the points (-6,4) and (-8, 6) can be found using the distance formula derived from the Pythagorean Theorem. After substituting and simplifying, we find the distance to be sqrt[8] or about 2.83 when rounded to two decimal places.
To find the distance between two points, we use the distance formula derived from the Pythagorean Theorem: d = sqrt[(x2 - x1)² + (y2 - y1)²].
Here, we are trying to find the distance between points (-6,4) and (-8, 6). We assign (-6,4) to (x1, y1) and (-8,6) to (x2, y2).
So, substituting into our formula we get: d = sqrt[(-8 - (-6))² + (6 - 4)²] = sqrt[(2)^2 + (2)^2] = sqrt[4 + 4] = sqrt[8] or about 2.83 when rounded to two decimal places.
