There are several bowls containing various amounts of grapes on a table. When 12 of the bowls each had 8 more grapes added to them, the mean (average) number of grapes per bowl increased by 6. How many bowls of grapes are on the table?
Answers
Answer:
There are 16 bowls
Step-by-step explanation:
Number of bowls = x
Total grapes added = 12 x 8 = 96
The average increased by 6
So 96/6 = 16
There were 16 bowls of grapes on the table
OR
12 x 8 = 96
96/6=16
Answer:
16 bowls
Step-by-step explanation:
Number of bowls = x
Total grapes added = 12 x 8 = 96
The average increased by 6
So 96/6 = 16
There were 16 bowls of grapes on the table
Vincent purchased a scooter for $124 before tax. The store adds a 7.8% sales tax to every purchase. How much did Vincent pay for the scooter, to the nearest penny?
Answers
Step-by-step explanation:
Original price of the scooter = $124
Sales Tax = 7.8%
Price of the scooter after tax = 124 + 7.8%(124)
= 124 + 7.8/100 x 124
= 124 + 3.9/50 x 124
= 124 + 1.95/25 x 124
= 124 + 0.39/5 x 124
= 124 + 0.39 x 24.8
= 124 + 9.672
= 133.672
Therefore, after tax the scooter will cost $133.672.

Ali is cutting a pizza into serving sized sections he uses a long knife to be sure that the cuts he makes in the pizza are straight which statements are true select all that apply
Answers
Answer:
1. Ali makes three straight long cuts along the diameter of the pizza.
2. Ali makes two straight long cuts along the diameter of the pizza.
Step-by-step explanation:
Each serving size in a pizza contains consistent weight but the fraction of the pie can change depending upon the size of the pizza., size of crust, toppings, etc.
The pizza can be cut into different pie section depending upon the size of the pizza. One-sixth or one-fifth is the most common pie sections.
Ali uses a long knife to cut the pizza in a straight line. He must cut the pizza in to 8 pieces or 4 pieces so that he can be sure that the pizzas are cut in a straight line.
For 8 pieces of pizza, Ali has to make three straight long cuts across three diameters of the pizza and for 4 pieces, Ali has to make two straight long cut along the diameters.

A cylindrical can, open at the top, is to hold 200 cm3 of liquid. Find the height and radius that minimizes the amount of material needed to manufacture the can.
Answers
Answer:
h = 5.42
r = 5.42
Step-by-step explanation:
Find h with respect to r:
V = πr²h = 500
h = 500/πr²
Plug this into the surface area equation:
SA = πr² + 2πrh
= πr² + 2πr(500/πr²)
= πr² + 1000/r
Differentiate and set to 0, solve for r:
dSA/dr = 2πr - 1000/r² = 0
2πr = 1000/r²
r³ = 500/π
r = (500/π)^1/3
≈ 5.42 cm
find h:
h = 500/πr²
= 500/[π(5.42)²]
= 5.42cm

Answers
Answer:
0.98 meters

(x,3) and (7,-5) given m= -8/7
Answers
Answer:
(0, 3)Step-by-step explanation:
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
[tex]m[/tex] - slope
[tex]b[/tex] - y-intercept
Given
[tex]m=-\dfrac{8}{7}[/tex]
and point [tex](7;\ -5)[/tex]
Substitute the value of the slope and the coordinates of the point ot the equation of a line:
[tex]-5=-\dfrac{8}{7\!\!\!\!\diagup}\cdot7\!\!\!\!\diagup+b[/tex] cancel 7
[tex]-5=-8+b[/tex] add 8 to both sides
[tex]-5+8=-8+8+b[/tex]
[tex]3=b\to b=3[/tex]
Therefore we have the equation of the line:
[tex]y=-\dfrac{8}{7}x+3[/tex]
Substitute (x, 3) to the equation:
[tex]3=-\dfrac{8}{7}x+3[/tex] subtract 3 from both sides
[tex]3-3=-\dfrac{8}{7}x+3-3[/tex]
[tex]0=-\dfrac{8}{7}x[/tex] divide both sides by (-8/7)
[tex]0=x\to x=0[/tex]
What is the percent of change from 5 to 9?
Answers
Hey there! It would be 44% decrease...
Explanation:
So we know that 9 would be 100%. So what is the percent of change?
So let divide 5 with 9. 5 divide 9 would be 0.56.
Great, now we can subtract 100 with 0.56 since we know that 56% is 5. 100-56 is 44. This means that the percent decrease would be 44%.
Final Result: 44%
The percent change from 5 to 9 is 80%.
What is percentage?Percentage is a measurement to find the value of a given number out of hundred.
Given that,
The original number is 5.
The number changes to 9 .
Increase in number = 9-5 = 4
The percentage change = 4/5×100 = 400/5 = 80%
The percentage change is 80% from 5 to 9.

y = 2
Second point (4, 2).
