The ratio of boys to girls in the 8th grade is 5:6. If there are 75 boys in the 8th grade, how many are girls?
Answer:
There are 15 girls
Step-by-step explanation:
Given:- Ratio of boys to girls = 5:3
And, the number of boys = 75
let the girls be 5x and boys be 3x
so, 5 × 75 { given }
x = 75/5 = 15
6x= 6 × 15 = 90
6x/6 = 90/6 = 15

Answer: it is called the slope intercept
Answer: Slope-intercept form
Step-by-step explanation:
The equation format of y = mx + b is slope-intercept.
-> m is the slope, or the steepness of the line
-> b is the y-intercept, or where the line intersects the y-axis.
division equation where 13 is quotient with the dividend a whole number and a unit fraction is the divisor
The division equation that has a quotient of 13 is 1/1/13 = 13
How to determine the equation?The given parameters are:
Quotient = 13Dividend = Whole numberDivisor = Unit fraction i.e. 1/n where n is an integer.A division equation is represented as:
Dividend/Divisor = Quotient
Substitute 13 for the Quotient
Dividend/Divisor = 13
Recall that:
Unit fraction = 1/n
So, we have:
Dividend/1/n = 13
Let n = 13.
So, we have:
Dividend/1/13 = 13
This gives
13 * Dividend = 13
Divide both sides by 13
Dividend = 1
So, we have:
1/1/13 = 13
Hence, the division equation is 1/1/13 = 13

To solve this problem, we have to use the area of both gauze or the dimensions on each gauze and compare them. we can see that the sheets are not similar as they have different areas.
Area of RectangleThe area of a rectangle is given as the product between the length and it's width.
Data;
Length = 9inArea = 45in^2width = ?length 2 = 4inwidth 2 = 3in[tex]area = length * width[/tex]
In the first gauze, the area is given as 45in^2 and we have value of the length. To find the width of the first gauze can be calculated as
[tex]A = length * width\\width = \frac{area}{length} \\width = \frac{45}{9} \\width = 5in[/tex]
We can see that the width are not equal so is their length.
But if we would truly compare them, the accurate way to do that is by their area
The area of the second gauze is given by
[tex]a = 3 * 4 = 12in^2[/tex]
From the above calculations, we can see that the sheets are not similar as they have different areas.

4. Five hamburgers and two French fries together contain 2160 calories, while four hamburgers and five French fries contain 2680 calories. What’s the calorie count in one hamburger and one pack of French fries?
Answer:
Hamburger is 320 calories. Pack of french fries is 280 calories
Step-by-step explanation:
Represent Hamburgers as H and pack of French Fries as P then set up the equations
5H+2P=2160
4H+5P=2680
Multiply the first equation by 5
25H+10P=10,800
Multiply the second by 2
8H+10P=5360
Subtract the first equation by the second
25H+10P=10,800
-
8H+10P=5360
=
17H=5440
H=320
One hamburger is 320 calories.
Plug in 320 for H
5(320)+2P=2160
1600+2P=2160
2F=560
F=280
One pack of french fry is 280 calories
3. The value of a car in relation to the number of miles driven is given by the linear
function y = -9x + 55000.
a. Interpret the meaning of the rate of change and initial value for the linear function.
Answer:
General form of a linear equation: [tex]y=mx+b[/tex]
(where m is the slope and b is the y-intercept)
A linear equation has a constant rate of change which is represented by the slope (m). It is the rate at which one quantity is changing with respect to another quantity.
Question 3Part (a)
Given equation: [tex]y=-9x+55000[/tex]
where:
y = value of car (in dollars)x = number of miles drivenThe rate of change (slope) is -9 and represents that for every 1 mile driven, the value of the car decreases by $9.
The initial value is the y-intercept (b) as this is the value when x = 0.
Therefore, the initial value of car is $55,000.
Part (b)
To find the number of miles at which the car be valued at $35,002, set the equation to $35,002 and solve for x:
[tex]\implies -9x+55000=35002[/tex]
[tex]\implies -9x=35002-55000[/tex]
[tex]\implies -9x=-19998[/tex]
[tex]\implies x=\dfrac{-19998}{-9}[/tex]
[tex]\implies x=2222[/tex]
Therefore, the car will be valued at $35,002 after 2,222 miles.
Question 4Given equation: [tex]y=0.39x+2.55[/tex]
where:
y = price of carrots (in dollars)x = weight (in oz)The rate of change (slope) is 0.39 and represents that for every increase of 1 oz of weight in carrots, the price of the carrots increases by $0.39
The initial value is the y-intercept (b) as this is the value when x = 0.
Therefore, the initial cost of the carrots is $2.55.
Part (b)
To find the weight of carrots you can buy for $6.06, set the equation to $6.06 and solve for x:
[tex]\implies 0.39x+2.55=6.06[/tex]
[tex]\implies 0.39x=6.06-2.55[/tex]
[tex]\implies 0.39x=3.51[/tex]
[tex]\implies x=\dfrac{3.51}{0.39}[/tex]
[tex]\implies x=9[/tex]
Therefore, you can buy 9 oz of carrots for $6.06
Part (c)
To find out how much it costs to buy 21 oz of carrots, substitute x = 21 into the equation and solve for y:
[tex]\implies y=0.39(21)+2.55[/tex]
[tex]\implies y=10.74[/tex]
Therefore, it costs $10.74 to buy 21 oz of carrots.
what is the equation of a parabola with a vertex at (6,4) and a=2?
Answer:
y = 2x² - 24x + 76
Step-by-step explanation:
the equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
here a = 2 and (h, k ) = (6, 4 ) , then
y = 2(x - 6)² + 4 ← in vertex form
expand factor using FOIL
y = 2(x² - 12x + 36) + 4 ← distribute parenthesis by 2
y = 2x² - 24x + 72 + 4
y = 2x² - 24x + 76 ← in standard form

The volume of the unit cell that is a simple cubic is 1.1661622e⁻²⁰.
What is Volume?Volume is the space occupied by a three-dimensional object.
By the formula of volume of atom
[tex]\rm Volume(atom) = \dfrac{4}{3} \times \pi \times r^3\\Volume(atom) = \dfrac{4}{3} \times \pi \times (161 \times 10^-^2^3)^3\\Volume(atom) = 2.1574e^-^2^1[/tex]

Find the x- and y-intercepts of the graph of y=−13x+3
Answer:
x-intercept: [tex]\frac{3}{13}[/tex] or about 0.231 which is also written as ([tex]\frac{3}{13}[/tex], 0)
y-intercept: 3 which is also written as (0, 3)
[Solution One]
We can find the answer by graphing. See attached. The points at which the line intersects the different axes is the answer.
[Solution Two]
We can solve by plugging into the equation. We will do this by setting the other variable, the one we aren't solving for, to 0.
For the x-intercept:
y = −13x + 3
(0) = −13x + 3
0 - 3 = -13x + 3 - 3
-3 = -13x
[tex]\frac{3}{13}[/tex] = x
For the y-intercept:
y = −13x + 3
y = −13(0) + 3
y = 3
