Jefferson Middle School needs to see a 300% gain in PTO fundraiser
sales from last year. If they sold a total of $2,420 last year, how much do
they need to sell this year to meet their goal? *
Given parameters:
Percentage gain = 300%
Selling cost last year = $2420
Unknown:
Selling cost this year = ?
Solution:
To solve this problem;
Profit percent = [tex]\frac{Selling cost this year - Selling cost last year}{Selling cost last year} x 100[/tex]
300 = [tex]\frac{S - 2420}{2420} x 100[/tex]
3 = [tex]\frac{S - 2420}{2420}[/tex]
S- 2420 = 7260
S = $9680
To make a 300% gain, Jefferson Middle school needs a $9680 from fundraiser sales this year.
Solve 2x2 – 23 = y when x = 1. y =
-16+2x= -64 what is the value of x
Answer:
add 16 to both sides so it would 2x=-48 then you would divide 2 on both sides so it would be x=-24
Step-by-step explanation:
X=-24
Answer:
-16 + 2x = -64
+16 +16
2x = -48
-48÷2=-24
x = -24

Answer:
908.563 in²Step-by-step explanation:
see attached image
A1 = 12 x 34 = 408
A2 = h = √(34² - 17²) = 29.445
= (1/2 * 34 * 29.445)
= 500.563
total area = A1 + A2
= 408 + 500.563
= 908.563 in²

times for their 40-yard dash.
What are the explanatory variable and response variable
for this relationship?
O Explanatory variable: season
Response variable: player weight
O Explanatory variable: season
Response variable: player 40-yard-dash time
O Explanatory variable: player weight
Response variable: player 40-yard-dash time
Explanatory variable: player 40-yard-dash time
Response variable: player weight
Answer:
Warning! The person above me is WRONG.
D is INCORRECT.
The correct answer is C.
Explanatory variable: player weight
Response variable: player 40-yard-dash time
The explanatory variable is the player's weight
The response variable is the player's 40-yard dash.
Option C is the correct answer.
What is explanatory and response variable?An explanatory Variable is a causal variable, which affects the other variable.
The response Variable is the resultant variable, which is affected by the other variable.
We have,
Football coaches running their summer practices noticed that the players who weighed more typically had slower times for their 40-yard dash.
We need to find what causes the player to have slower times.
The weight of the players causes the players to have slower times.
So,
Player weight is the explanatory variable and the response variable is the time for their 40-yard dash.
Thus,
The explanatory variable is the player's weight
The response variable is the player's 40-yard dash.

Put this equation into slope- intercept form. -2x + 3y = 9
Answer:
y = 2/3x + 3
Step-by-step explanation:
In order to put it in slope intercept form (y = mx + b), y needs to be isolated.
Add 2x to both sides:
-2x + 3y = 9
3y = 2x + 9
Then, divide both sides of the equation by 3.
3y = 2x + 9
y = 2/3x + 3 is the equation in slope intercept form
Answer:
Slope-intercept form:
→ y = (2/3)x + 3
Step-by-step explanation:
Given equation,
→ -2x + 3y = 9
Now we have to,
→ Convert this given equation into the slope-intercept form.
The slope-intercept form is,
→ y = mx + b
Let's convert the equation,
→ -2x + 3y = 9
→ 3y = 9 + 2x
→ 3y = 2x + 9
→ y = (2x + 9)/3
→ y = (2x/3) + (9/3)
→ y = (2/3)x + 3
From this slope-intercept form:
→ Slope (m) = 2/3
→ y-intercept (b) = 3
Thus, the answer is y = (2/3)x + 3.

Answer:
1/3000 or 0.000333....
Step-by-step explanation:
I think you mean 20mm / 60 m
1 mm = 0.001m
So the division becomes:
(0.001* 20) / 60
= 0.02 / 60
= 0.00033.....
or as a fraction it is
2/6000
= 1/3000.
