Answer:
$320
Step-by-step explanation:
First, convert the percentage to a decimal.
4% = 0.04
Now, you have to multiply the price by the decimal to find his commission.
8000 * 0.04 = 320
He made a commission of $320.
Answer:
n ≥ -12
Step-by-step explanation:
Change the less than or equals sign to an equals sign
-7(n+7) = 35
Use distributive property to figure out what -7(n+7) equals
-7n-49 = 35
Add 49 to both sides
-7n = 84
Divide both sides by -7
n = -12
Bkuz you want n -7(n+) to be less than or equal to 35 you have to change the equals sign in n = -12 to a greater or equal to sign
Hope this helps!
X >= (at least symbol) $9 since she needs AT LEAST 20$ and she already has 12$ so 12+9>20
Answer:
The height at time of 12.1 seconds is approximately 729.2562 feet
Step-by-step explanation:
The general form of the quadratic regression equation is y = A + Bx + Cx²
The quadratic regression formula is given as follows;
Solving using an online quadratic regression calculator, gives;
A = 2.5643259
B = 246.6374865
C = -15.41986006
Substituting gives;
y = 2.5643259 + 246.6374865·x -15.41986006·x²
When time, x = 12.1, we have;
y = 2.5643259 + 246.6374865×12.1 -15.41986006×12.1²≈ 729.2562 feet
The height at time of 12.1 seconds ≈ 729.2562 feet.
