8 is what percent of 64?
Answers
Answer:
The answer is 12.5
Steps:
8:64*100 =
( 8*100):64 =
800:64 = 12.5
All the steps:
Now we have: 8 is what percent of 64 = 12.5
Question: 8 is what percent of 64?
Percentage solution with steps:
Step 1: We make the assumption that 64 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: From step 1, it follows that %100=64
Step 4: In the same vein, x%=8.
Step 5: This gives us a pair of simple equations:
%100=64(1)
x%=8(2)
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100%/x% = 64/8
Step 7: Taking the inverse (or reciprocal) of both sides yields
x%/100% = 8/64
x =12.5%
Therefore, 8 is 12.5% of 64.

solve 3x + 4 = 5x + 28
Answers
Answer:
x = -12
Step-by-step explanation:
Step 1: Subtract 5x from both sides.
3x + 4 - 5x = 5x + 28 - 5x
-2x + 4 = 28
Step 2: Subtract 4 from both sides.
-2x + 4 - 4 = 28 - 4
-2x = 24
Divide both sides by -2.
-2x/-2 = 24/-2
x = -12

An environmentalist tracks the total number of trees y in a park after x years of a planting program. The line of best fit for the data is represented by the equation y = 4x + 15. What is the percent change in the total number of trees from x = 3 to x = 6? Round your answer to the nearest percent.
Answers
Answer:
44.4%
Step-by-step explanation:
Given that:
Equation of best fit : y = 4x + 15
Where, y = number of trees x years after a planting program
When x = 3
y = 4(3) + 15 = 12 + 15 = 27 trees
When x = 6
y = 4(6) + 15 = 24 + 15 = 39 trees
Percentage change in total number of trees:
((39 - 27) / 27) * 100%
(12 / 27) * 100%
0.44444 * 100%
= 44.4%

Emily wins 22000$. She has to pay 10% for charity and then she decides to buy a car for 10800$. She divides the rest of them between her son and daughter in the ratio 1:4. How much does her daughter get.
Answers
Answer:
$7 200
Step-by-step explanation:
Amount of money paid for charity = [tex]\frac{10}{100}[/tex] × $22 000
= $2 200
Remaining money left for children = $22 000 - $2 200 - $10 800
= $9000
Let the amount of money her son receives be x and the amount her daughter gets be 4x.
Son's $ + Daughter's $ = $9000
x + 4x = 9000
5x = 9000
Amount of money her daughter gets (4x) = [tex]\frac{4}{5}[/tex] × 9000
= $7 200

During the first week of school Andrew purchased two pounds of Jellies and two pounds of Bonbons for $38. The second week of school he purchased two pounds of Jellies and four pounds of Chocolates for $74 and the third week he purchased two pounds of Jellies, two pounds of Bonbons and one pound of Chocolates for $53. What is the cost of one pound of Chocolates?
Answers
Answer:
j = $7
b = $12
c = $15
Step-by-step explanation:
Let
j = cost of one pound of jelly
b = cost of one pound of Bonbon
c = cost of one pound of chocolate
First week:
two pounds of Jellies and two pounds of Bonbons for $38.
2j + 2b = 38
Second week:
two pounds of Jellies and four pounds of Chocolates for $74
2j + 4c = 74
Third week:
two pounds of Jellies, two pounds of Bonbons and one pound of Chocolates for $53.
2j + 2b + c = 53
Recall,
2j + 2b = 38
So,
38 + c = 53
c = 53 - 38
= 15
c = $15
Substitute c = 15 into
2j + 4c = 74
2j + 4(15) = 74
2j + 60 = 74
2j = 74 - 60
2j = 14
j = 14/2
= 7
j = $7
Substitute j = 7 into
2j + 2b = 38
2(7) + 2b = 38
14 + 2b = 38
2b = 38 - 14
2b = 24
b = 24/2
= 12
b = $12

120% of x is 96. What is x?
Answers
Answer:
Step-by-step explanation:
You can do this using a small equation.
120% x = 96 Change 120% to a decimal
120/100 * x = 96 Multiply by 100
120x = 96 * 100
120x = 9600 Divide by 120
x = 9600/120
x = 80
Look what you got. 20% more than 80 is 96. x is smaller than 96.
If you take 20/100 * 80 = 16
if you add 16 to 80, you get 96
Answer:
x = 80
Step-by-step explanation:
120 % of x = 96
or, 120/ 100 × x = 96 change percentage to 100 and devide
or, 6 / 5 × x = 96
or, 6x / 5 =96. multiply 6 and x
or, 6x = 96 × 5. change devide sign to multiply
or, 6x = 480. multiply
or, x = 480 / 6. change multiply sign to devide
therefore, x = 80

Step-by-step explanation:
I will say that to know if its rational, you have to see if the integer can be written in a fraction (like 0.333, 89/10, -4, 0)
Answer:
Whole numbers: 3, [tex]\sqrt{4}[/tex], [tex]\frac{49}{7}[/tex], zero
Integer but not whole: -100, -34, -4, -[tex]\frac{8}{4}[/tex]
Rational number: 9.23456, [tex]\frac{1}{2}[/tex], [tex]\frac{89}{10}[/tex], 0.333_
Irrational number: [tex]\pi[/tex], 0.456783_, [tex]\sqrt{8}[/tex]
Step-by-step explanation:
Whole number is any number that does not have a decimal and is not negative. [tex]\sqrt{4}[/tex] = 2. [tex]\frac{49}{7}[/tex] = 7. 0 is not negative and does not have a decimal so it is also a whole number.
Integers are any number that does not have a decimal and can be both positive or negative. -[tex]\frac{8}{4}[/tex] = -2.
A rational number can have a decimal but the decimal digits must terminate or the digit must repeat. [tex]\frac{1}{2}[/tex] is 0.5. [tex]\frac{89}{10}[/tex] is 8.9 and 0.333_ repeats the digit 3 so it is rational.
An irrational number can have a decimal and the decimal digits must list on forever or not repeat. [tex]\pi[/tex] is naturally an irrational number as it does not repeat and it spreads on forever. 0.456783_ does not repeat and goes on forever due to the dash at the back. [tex]\sqrt{8}[/tex] is also not rational.
