Last year, the number of students enrolled in the school was 672. If this number increases by 12% the next year, how many students will there be?
What an amount is increased by a percent, add the percent change to 100. 100 + 12 = 112. Use the proportion \frac{}{100}=\frac{is}{of} to get \frac{112}{100}=\frac{x}{100}[tex]\frac{112}{100}=\frac{x}{100}[/tex].
Answer:
Step-by-step explanation:
672 x 12% = 80.64
80.64 is going to be added...
672 + 80.64 = 752.64 ≈ 753 students...
hope this works...

. When a number is multiplied by 4 before
subtracting from 68, the result obtained is
the same as three times the sum of the number
and 4. Find the number.
Answer:
14
Step-by-step explanation:
if you by multiply 4 by 3 because the sum of three times the sum of the number to get 12
then we multiply 4 by 14 to get 56
then we subtract 68 by 56 to get 12 that is the same number we got from multiplying the 4 and 3 to get 12
so the answer is 14
Find the product of 2x4(4x2 + 3x + 1). (1 point)
a
8x6 + 6x5 + 2x4
b
8x8 + 3x4 + 2x4
c
2x4 + 6x5 + 8x6
d
6x6 + 5x5 + 3x4
The Answer Is 72+24x
Use the distributive property to find the answer.
8(8+3x+1)=64+24x+8
Meaning,
2x4(4x2+3x+1)=72+24x
What is 8 x 8 x 8 in exponential form
Answer:
10^3
Step-by-step explanation:
103 is read as “10 to the third power” or “10 cubed.” It means 10 • 10 • 10, or 1,000.
82 is read as “8 to the second power” or “8 squared.” It means 8 • 8, or 64.
54 is read as “5 to the fourth power.” It means 5 • 5 • 5 • 5, or 625.
b5 is read as “ b to the fifth power.” It means b • b • b • b • b. Its value will depend on the value of b.
The exponent applies only to the number that it is next to. So in the expression xy4, only the y is affected by the 4. xy4 means x • y • y • y • y.
If the exponential expression is negative, such as −34, it means –(3 • 3 • 3 • 3) or −81.
If −3 is to be the base, it must be written as (−3)4, which means −3 • −3 • −3 • −3, or 81.
Likewise, (−x)4 = (−x) • (−x) • (−x) • (−x) = x4, while −x4 = –(x • x • x • x).

At a store, apples cost each and oranges cost each. Harry buys some apples and oranges and spends . He buys a total of pieces of fruit.
Answer:
Number of apples = 6
Number of oranges = 5
Step-by-step explanation:
At a store, apples cost $0.80 each and oranges cost $0.95 each. Harry buys some apples and oranges and spends $9.55. He buys a total of 11 pieces of fruit.
Let
Number of apples = x
Number of oranges = y
x + y = 11 (1)
0.80x + 0.95y = 9.55 (2)
From (1)
x = 11 - y
Substitute into (2)
0.80x + 0.95y = 9.55 (2)
0.80(11 - y) + 0.95y = 9.55
8.8 - 0.80y + 0.95y = 9.55
- 0.80y + 0.95y = 9.55 - 8.8
0.15y = 0.75
y = 0.75/0.15
y = 5
Substitute y = 5 into (1)
x + y = 11 (1)
x + 5 = 11
x = 11 - 5
x = 6
Number of apples = 6
Number of oranges = 5
What is the area of the triangle?
4
2
units?
The area of the triangle whose base is 4 unit and height is 2 unit is 4 square units .
To calculate the area of a triangle, we multiply the base by the height and divide the result by 2 .
Base of triangle = 4 units
Height of triangle = 2 units
Area of triangle = ( Base of triangle * Height of triangle ) / 2
Area of triangle = ( 4 * 2 ) / 2
Area of triangle = 8 / 2
Area of triangle = 4 square units
Therefore, the area of the triangle is 4 square units .

If OPQ is dilated from point Q by a scale factor of 3, which of the following equations is true about R'S'?
Answer:
segment R prime S prime = three segment RS
Step-by-step explanation:
I took the test,
The true statement is segment R prime S prime = three segment RS
What is dilation?Dilation is a transformation, which is used to resize the object.
The complete question is
If ΔOPQ is dilated from point Q by a scale factor of 3, which of the following equations is true about segment R prime S prime?
Triangle OPQ is shown with point R lying on side OP and point S lying on side OQ Line RS is perpendicular to side OQ.
segment R prime S prime = one half segment RS
segment R prime S prime = two segment RS
segment R prime S prime = segment RS
segment R prime S prime = three segment RS
The scale factor of dilation of ΔOPQ, S.F. = 3
S'Q' = 3 * SQ
also, R'Q' = 3* RQ
By Pythagoras theorem, we have
R'Q'² = R'S'² +S'Q'²
R'S'² = R'Q'² - S'Q'²
R'S'² = (3RQ)² - (3SQ)²
R'S'² = 9(RQ² - SQ²)
R'S' = 3 RS

Dude I need help this is due in an hour!!!
Answer:
75
Step-by-step explanation:
He can read = 250w/m
2 hours = 60 x 2 = 120 min
Number of words he can read in 2 hours = 250 x 120 = 30,000
No: of words in each page = 400
No: of pages he reads = 30,000/ 400 = 75

Amaya went to the pet store. She bought x fish for $3.50 each. She bought fish food for $7.00, and a fish bowl for $12.75. Determine how much Amaya spent at the pet store if she bought 4 fish.
Answer:
$93
Step-by-step explanation:
Amaya went to the pet store. She bought x fish for $3.50 each. She bought fish food for $7.00, and a fish bowl for $12.75. Determine how much Amaya spent at the pet store if she bought 4 fish.
Step 1
We calculate the total amount spent on 1 fish
= Cost of fish + Cost of food + Cost if bowl
= $3.50 + $7.00 + $12.75
= $23.25
Step 2
The total amount spent on 4 fishes is calculated as
= $23.25 × 4 fishes
= $93

Answer:
Step-by-step explanation:
Since we have points (-1,5) and (3,4) we can find the slope m of y=mx+b
m=(y2-y1)/(x2-d1)=(5-4)/(-1-3)=1/-4=-1/4 so we have
y=-x/4+b, using point (3,4) we can solve for the y intercept, b.
4=-3/4+b, b=19/4, so the line is
y=(-x+19)/4

S. At Food Lion, 28 of every 35 jars of peanut butter on the shelves are creamy peanut butter. What percent of the jars of peanut butter are not creamy?
Answer:
7/35 or 20% of the jars are not creamy
Answer:
20%
Step-by-step explanation:
To find the percent of NOT creamy:
35(total peanut butter) - 28(creamy) = 7
Question now is: 7 is what % of 35?
Formula = a(part) = p(percent)*w(whole)
p = a/w
7/35 = 0.2
0.2 is a decimal so multiply by 100 to get 20%
The answer should be 20% so I hope this helps!

Answer:
∠ GJK = 22°
Step-by-step explanation:
∠ HJI = ∠ JHG ( alternate angles ), then
7x - 16 = 5x + 8 ( subtract 5x from both sides )
2x - 16 = 8 ( add 16 to both sides )
2x = 24 ( divide both sides by 2 )
x = 12 , so
∠ KJI = 7x - 16 = 7(12) - 16 = 84 - 16 = 68°
Then
∠ GJI = 90° ( vertex of a rectangle )
∠ GJK = 90° - 68° = 22°

At Cindy's birthday each guest will get one-third of a medium sized pizza. There will be 12 people at the party, including Cindy. How many pizza's does her mom need? awnser is 6
Answer: 4 pizzas
Step-by-step explanation:
There are to be 12 people at the party.
Each person is expected to take 1/3 of a pizza.
The total number of pizza needed is therefore:
= No. of people * quantity of pizza
= 12 * 1/3
= 4 pizzas
Note: Answer would be 6 if each guest wanted 1/2 of a pizza.

Answer:
28 points per game
42 miles per gallon
$2.99 per bag
Step-by-step explanation:
140 points in 5 games. To find the amount of points in one game, we divide the total points by the total games: 140/5=28
504 miles with 12 gallons. To find the amount of miles with one gallon, we divide the total miles by the total gallons: 504/12=42
$8.97 for 3 bags. To find the amount of dollars for one bag, we divide the total amount of dollars by the total bags: 8.97/3=2.99
