6 is what percent of 8
The number 6 is 75 percent of 8
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a' the percent that considered thing is of "a" is b%. Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts.
We need to find the number that is state 25% of number is 1.
Let the unknown number is represneted by b.
It can be written by;
x% x 8 = 6
6/8 = 0.75
0.75 x 100
x= 75%
Therefore, the percent would be 75%

how can you calculate the area of the circle if you know the circle's circumference?
Answer with step-by-step explanation:
We know that the formula for area of a circle is given by:
Area of a circle = [tex] \pi r ^ 2 [/tex]
So to find the area of circle, we basically need to know the radius of the circle.
If we know the circumference of the circle, we can calculate the area of the circle too.
Formula for the circumference of the circle is given by:
[tex]2\pi r[/tex]
So if we know the circle's circumference, we can find the value of radius and then find the area of circle with it.
Answer:
We can calculate area of circle if we know the circumference
Step-by-step explanation:
Points to remember
`1). Circumference of circle = 2πr
2). Area of circle = πr²
Where 'r' is the radius of circle
Find area of circle
From the above two equations we have to calculate area and circumference of a circle with radius.
If we have circumference, the we can calculate radius of the circle
r = circumference/2π
If we get radius 'r' the we can calculate area
Area of circle = πr²
a small airplane flies 750 miles with an average speed of 300 miles per hour. 1 hour after the plane leaves, a Boeing 747 leaves from the same point. both planes arrive at the same time, what was the average speed of the 747
Final answer:
To calculate the Boeing 747's average speed, you subtract the one hour it departs after the small plane from the total travel time of the small plane and divide the same distance of 750 miles by this new time. The 747's average speed is found to be 500 mph.
Explanation:
The question asks for the average speed of a Boeing 747 that departs one hour after a small airplane and arrives at the same time. The small airplane travels 750 miles at an average speed of 300 miles per hour (mph). To find the average speed of the 747, we first calculate the time it takes for the small airplane to reach the destination:
Time = Distance ÷ Speed = 750 miles ÷ 300 mph = 2.5 hours
The 747 leaves an hour later, so its travel time is 2.5 hours - 1 hour = 1.5 hours. The 747 covers the same 750 miles in this shorter time frame:
Average speed of 747 = Distance ÷ Time = 750 miles ÷ 1.5 hours = 500 mph
The computed result is that the 747's average speed is 500 mph to cover the same distance and arrive simultaneously with the small airplane.

Chad's family traveled [tex]\frac{5}{8}[/tex] of the distance to his grandmother’s house on Saturday. They traveled [tex]\frac{1}{3}[/tex] of the remaining distance on Sunday. What fraction of the total distance to his grandmother’s house was traveled on Sunday?
a whole or 1, is when the numerator and denominator are the same, namely 2/2, 3/3, 10000/10000 is a whole.
on Saturday they travelled 5/8 of the way, now, the whole being 8/8, so if we take 5/8 from 8/8, we're simply left with 3/8, that's the remaining distance to grandmas house.
on Sunday they travelled 1/3 of that remaining amount, how much is that? well, is simply their product,
[tex]\bf \cfrac{3}{8}\cdot \cfrac{1}{3}\implies \cfrac{3}{3}\cdot \cfrac{1}{8}\implies \cfrac{1}{8}[/tex]

Hayley Baked A Cheescake. She used 5/8 pound cream cheese, 4/16 pound sugar, and 6/8 pound peaches. How much did the ingredients weigh altogether?
8 is a factor of 16, so you would multiply the numerator and denominator of 5/8 and 6/8 by 2. this would be 10/16 and 12/8. add all of the numbers together = 10+12+4 which equals 26. it’d be 26/16 or 1 and 10/16.
Answer:
1[tex]\frac{5}{8}[/tex]
Step-by-step explanation:
equation: [tex]\frac{5}{8}[/tex]+[tex]\frac{14}{16}[/tex]+[tex]\frac{6}{8}[/tex]=x
but we cannot solve this because not all of the fractions have an equal denominator. so, we can multiply [tex]\frac{5}{8}[/tex] and [tex]\frac{6}{8}[/tex] each by two.
why?
because 8x2 is 16 and if you multiply them you get a common denominator of 16, making it way easier to add up the fractions.
so, what you do to the top you do to the bottom:
[tex]\frac{5}{8}[/tex] [tex]\frac{x2}{x2}[/tex] [tex]\frac{10}{16}[/tex] [tex]\frac{6}{8}[/tex] [tex]\frac{x2}{x2}[/tex] [tex]\frac{12}{16}[/tex]
so, [tex]\frac{10}{16}[/tex]+[tex]\frac{12}{16}[/tex]+[tex]\frac{4}{16}[/tex] equals to [tex]\frac{26}{16}[/tex].
[tex]\frac{26}{16}[/tex] = 1 [tex]\frac{10}{16}[/tex].
however 1[tex]\frac{10}{16}[/tex] can be simplified more.
divide top and bottom by 2 and get 1[tex]\frac{5}{8}[/tex]

find missing number. show work. 120-35=100-?=60+?
Answer:
15 and 25
Step-by-step explanation:
First find 120-35=85
so 100-?=85 so ?=15
and 60+?=85 so ?=25
Answer: 120-35= 100 - 15 = 60 + 25
Step-by-step explanation:
You are just trying to make them all equal to 85 because the original sum of 120-35 is 85. so you are setting the rest of the equations to 85 as well.
Subtract.
(5x^2 - 3x - 2) - (-2x^2 - +10)
Express the answer in standard form.
Enter your answer in the box
Answer:
7x^(2)-3x+8
Step-by-step explanation:
(5x^(2) - 3x - 2) - (-2x^(2) - +10)
(5x^(2))- (-2x^(2))=7x^(2)
(- 2)-(+10)=+8
7x^(2)-3x+8
Final answer:
To subtract (-2x² + 10) from (5x² - 3x - 2), change the signs of the second polynomial and combine like terms. The final result is 7x²- 3x - 12.
Explanation:
The question asks to subtract one polynomial from another, specifically to subtract (-2x²+ 10) from (5x² - 3x - 2). The subtraction of polynomials involves changing the signs of the polynomial being subtracted and then combining like terms. The process will be as follows:
First, change the signs of the second polynomial: -(-2x²) becomes +2x², and -(+10) becomes -10.
Then, combine the like terms with the first polynomial: (5x² + 2x²) becomes 7x², -3x stays the same as there are no like terms, and (-2 - 10) becomes -12.
Therefore, the answer in standard form is 7x²- 3x - 12.
you are making a fresh fruit salad using cantaloupe how much cantaloupe (AP) would you have to order if you needed 15 pounds (EP) and if canaloupe has a 55 percent yield?
Answer:
You would need to order 28 pounds. (27.27...)
Step-by-step explanation:
Let x be the number of cantaloupe. Then, 0.55x-=15.
0.55x=15
55x=1500
11x=300
x=300/11
x=27.27...
To make fruit salad using cantaloupe, you would need to order 28 pounds (AP) if you only need 15 pounds (EP) and the cantaloupe has a 55% yield.
Explanation:To determine how much cantaloupe (AP) you would need to order, you need to consider the yield percentage. If the cantaloupe has a 55% yield, it means that 55% of the cantaloupe will be usable. So, you need to order more than 15 pounds (EP) to account for the reduced yield.
To calculate the amount of cantaloupe (AP) to order, you can use the formula:
AP = EP / Yield Percentage
Using the given values, the calculation would be:
AP = 15 pounds / 55% = 27.27 pounds
Rounded up to the nearest whole number, you would need to order 28 pounds of cantaloupe (AP) to obtain 15 pounds (EP) with a 55% yield.

Two cars left the city for a suburb, 120 km away, at the same time. The speed of one of the cars was 20 km/hour greater than the speed of the other, and that is why it arrived at the suburb 1 hour before the other car. Find the speeds of both cars.
Answer:
V1 = 60 km/h
V2 = 40 Km/h
Step-by-step explanation:
The speed of an object is defined as
Speed = distance / time
Let
V1 be the speed of the faster car
V2 be the speed of the other car
t1 the time it took for the first car to arrive
t2 the time it took for the second car to arrive
d1 the distance traveled by first car
d2 the distance traveled by second car
We know thanks to the problem that
V1 = V2 + 20 Km/h
t1 = t2 - 1 hour
d1 = d2 = 120 Km
d1 = V1 * t1
d2 = V2* t2
V1 * t1 = V2* t2
V1* t1 = (V1 -20)*(t1 +1)
The system of equations
(V1 -20)*(t1 +1) = 120
V1 * t1 = 120
120 + (120/t1) -20*t1 = 140
(120/t1) -20*t1 = 20
Which gives,
t1 = 2
This means
V1 = 60 km/h
V2 = V1 - 20 Km/h = 40 Km/h
Answer: 60 km/h, and 40 km/h

Answer: d - (d x .1)
Step-by-step explanation: The expression that will show how much the actor will earn is d - (d x .1). D is the actor’s earnings and d x .1 is the commission of their agent.
Final answer:
The expression that shows how many dollars the actor will earn this year after the agent's commission is deducted is d - 0.1d. The agent collects a commission of 10% of the actor's earnings, which is subtracted from the total earnings.
Explanation:
The expression that shows how many dollars the actor will earn this year after the agent's commission is deducted is:
d - 0.1d
Since the agent collects a commission of 10% of the actor's earnings, we can multiply the earnings by 0.1 to find the amount of commission. Subtracting this amount from the total earnings gives us the amount the actor will earn after the commission is deducted.

Claire got 85% of the questions correct on her vocabulary quiz by answering 17 out of 20 questions correctly.
Claire got 17 out of 20 questions correct on her vocabulary quiz. To calculate the percentage of questions Claire got right, you would use the following formula:
Percentage Correct = (Number of Correct Questions \/ Total Number of Questions) x 100%
Applying Claire's numbers to this formula:
Percentage Correct = (17 \/ 20) x 100% = 0.85 x 100% = 85%
Therefore, Claire got 85% of the questions correct on her quiz. This is a high percentile, which indicates she did very well, considering that seventy percent of students answered 16 or fewer questions correctly and thirty percent of students answered 16 or more questions correctly. A higher percentile is generally considered good, as it means answering more questions correctly, which is desirable.
