Given parameters:
Number of boxes Athena bought for the party = x
Number of cookies per box = 10
Number of cookies she brought to the party = 70
Number removed = 2 boxes
Unknown:
Equation of the number of boxes = ?
Solution:
1 box of cookies contains 10 cookies
If Athena, removed 2 boxes, in those two boxes, we have 20 cookies
Total number of cookies = 70 + 20 = 90 cookies;
So;
x = [tex]\frac{total number of cookies}{number of cookies per box}[/tex]
Therefore;
x = [tex]\frac{90}{10}[/tex]boxes

1/5p=15
Pls solve in steps forgot how to do it lol
Answer:
(1/5)*p = 15 // - 15
(1/5)*p-15 = 0
1/5*p-15 = 0 // + 15
1/5*p = 15 // : 1/5
p = 15/1/5
p = 75
p = 75
Answer:
p=75 cause that's just it
A bird leaves its nest and travels 15 miles per hour downwind for x hours. On the return trip, the bird travels 3 miles per hour slower and has 2 miles left after x hours.
a. What is the distance of the entire trip?
miles
b. How long does the entire trip take?
_hours
_minutes and
_seconds
Answer:
A)
10 miles.
B)
0 hours, 40 minutes, and 0 seconds.
Step-by-step explanation:
Remember that distance is given by the formula:
[tex]d=st[/tex]
Where d is the distance, s is the speed, and t is the time.
We know that the bird leaves its nest and travels 15 miles per hour for x hours. So, let's substitute 15 for s and x for t:
[tex]d=15x[/tex]
On the return trip, the bird travels 3 miles per hour slower and has 2 miles left after x hours.
Since this is the return trip, the distance d remains the same. We know that the bird travels 3 miles per hour slower, so it's speed is 15-3 or 12 miles per hour.
However, after x hours, it still has 2 miles left until reaching the destination. So, we will subtract 2 from d. This gives us the equation:
[tex]d-2=12x[/tex]
We can solve this using substitution. Since we already know that d is 15x. Substitute:
[tex]15x-2=12x[/tex]
Solve for x. Subtract 12x from both sides:
[tex]3x-2=0[/tex]
Add 2 to both sides:
[tex]3x=2[/tex]
Divide both sides by 3:
[tex]x=2/3[/tex]
Therefore, the bird traveled for a total of 2/3 hours or 40 minutes.
And the distance the bird traveled is:
[tex]d=15x[/tex]
Substitute 2/3 for x to get:
[tex]d=15(2/3)=30/3=10\text{ miles}[/tex]

A triangle has a base of 10 inches and a height of 8 inches. What percent of the area of the triangle is within 4 inches of the base?
Answer:
40%
Step-by-step explanation:
Firstly
Area of triangle when base is 10 inches and height is 8 inches
= 1/2*b*h
= 1/2*10*8
=40square inch
Again when base =4 inches
= 1/2*4*8
= 16square inches
percent of the area of the triangle is within 4 inches of the base
= 16/40*100%
= 40%
A triangle has an 8-inch height and a 10-inch base. The percent of the area of the triangle is within 4 inches of the base exists 40%.
What is meant by the area of triangle?Area of triangle = 1/2 (b h), where b is the base and h is the height, is the fundamental formula for calculating a triangle's area.
The type of the triangle and the known dimensions can affect other formulas that are used to calculate the area of a triangle.
Given: A triangle has an 8-inch height and a 10-inch base.
Let the equation be
Area of a triangle = (1/2) bh
substitute the values in the above equation, we get
= (1/2) × 8 × 10
= 40 square inches.
Once more with a 4 inch base
= 1/2 × 4 × 8
= 16 square inches.
Within 4 inches of the base, % of the triangle's surface area
= 16/40 × 100%
= 40%
Therefore, the percent of the area of the triangle is within 4 inches of the base exists 40%.

A is directly proportional to the square root of B
When A = 50, B+4 . Find A in terms of B
Answer:
A=50, B=4
A is directly proportional to the square root of B
name the constant 'k'
A = k*B^0.5
50 = k*4^0.5
50=2k
k=25
=> A =25 root B
i.e, A = 25*B^0.5 (The answer should be written the way it is written in the attached picture)
A written in terms of B is 25√B.
What is direct and inverse proportion ?In direct proportion if one quantity increases the other quantity also increases and vice versa.In case of inverse proportion when one quantity increases the other quantity decreases and vice versa.
According to the given question A is directly proportional to the square root of B.
∴ A = K[tex]\sqrt{B}[/tex]
Given when A = 50 B = 4.
50 = K[tex]\sqrt{4}[/tex]
50 = 2k
k = 25.
So, A =25√B.

farmer has 120 bushels of wheat to sell at her roadside stand. She sells an average of 16
5
8 bushels each day. Represent the total change in the number of bushels she has for sale after 5 days.
Answer:
The total change in the number of bushels she has for sale after 5 days is 83.125 bushels
Step-by-step explanation:
The given parameters are;
The initial number pf bushels the farmer has = 120 bushels
The amount of bushels of wheat the farmer sells each day = 16⁵/₈ = 16.625
The number of bushels sold after 5 days = 16.625 × 5 = 83.125 bushels
The total change in the number of bushels she has for sale after 5 days = The number of bushels sold after 5 days
The total change in the number of bushels she has for sale after 5 days = 83.125 bushels.

choices
15
13
10
11
Answer:
10 water stations are needed
Step-by-step explanation:
To get the number of water- station needed, we simply divide the total length of the half marathon by the distance where we can find a water station
mathematically,
that would be 13.1 divided by 1 1/3
= 13.1 divided by 4/3
= 13.1 * 3/4 = 9.825 which is approximately 10

Find the slope and write an equation of the line which passes through the points. (−3, 9) and (−3, −5)
Answer:
Slope: undefined
Equation: x=-3
Step-by-step explanation:
To find the line that passes through the points, you first want to find the slope. The formula for slope is [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. Once we have the slope, we can use any given point to plug in to find the y-intercept.
[tex]m=\frac{-5-9}{-3-(-3)} =\frac{-14}{0}[/tex]
We can see that the slope is undefined. If we look at the point, we notice that they both have the same x-coordinate. This let's us know that the equation is x=-3.
