Answer:
x = 49
Step-by-step explanation:
1- Substitute g ( x ) = 0
Reduce
g ( x ) = - x 2/4 + 7
2- Move the variable to the left
0 = - x 1/2 + 7
3- Simplify the equation
x 1/2 = 7
4- Simplify Evaluate
( x 1/2 ) ² = 7²
5- Check the solution
x= 49
6- Simplify
0= - 49 2/4 + 7
7- x = 49 is a solution
0 = 0
This is the formula for the surface area where r is the radius and h is the height. Finding the surface area will determine how much wrapping paper Jill needs (in inches squared).
The base measures 4 inches across. This means that the diameter is 4 inches. The radius is half the diameter (always). Thus, the radius is 2 inches. This means that r=2
The height is 10 inches. This means that h=10
The questions says to use 3.14 for π.
Use a calculator for this. Doing this by hand will take a painful amount of time.
This was what I got from a calculator. I did not round at all.
The surface area is 150.72 inches squared. Thus, Jill will need 150.72 inches squared of wrapping paper. I hope this is what you needed to help you understand! :)
Answer:
$43.13
Step-by-step explanation:
The original price plus the markup = selling price
The markup = original price * percent markup
So
selling price = original price + original price* percent markup
Factoring out the original price
selling price = original price (1+ percent markup)
Substituting what we know)
69 = original price (1+.60)
69 = original price(1.6)
Divide both sides by 1.6
69/1.6 = original price
43.125 = original price
We round money to the nearest cent
$43.13
Anything less than 12 (must be positive numbers and it mustn’t be 0) is greater than 0.
Divide amount of grapes by number of people.
= 1/2 lb ÷ 4 people
to divide a fraction, multiply by the reciprocal (inverse)
= 1/2 * 1/4
= (1*1)/(2*4)
= 1/8 pound
ANSWER: Each of the 4 people will get 1/8 pound of grapes.
Hope this helps! :)
