Answer: 75% Of the original price

Step-by-step explanation:

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.

The number 6 is 75 percent of 8

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%

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.

Answer:

Area = 260

Step-by-step explanation:

The formula for the area of a 6-gon is

Area = 3*sqrt(3) * side^2 / 2

side = 10

Area = 3 * 1.7321 * 100/2

Area = 259.8

Area = 260

Answer: n=16

Step-by-step explanation:

The solution to the equation is n = 16.

The equation 1/2 * n = 8 can be solved by multiplying both sides by 2 to find n = 16.

To solve the equation 1/2 * n = 8:

Multiply both sides by 2 to isolate n: n = 8 * 2 = 16.

Therefore, the solution to the equation is n = 16.

Break it down into shapes you know. There's a triangle and a rectangle. The area of a rectangle is l*w and in this case it's 5*6 or 30 units². The area of a triangle is 1/2b*h and in this case that is 1/2 * 6 * 3 or 9 units². Add the areas together to find the total area, which is 39 units².

This line is in slope intercept form y = mx+b

Since we can write it as y = (-5/3)x + 0

m = -5/3 is the slope

b = 0 is the y intercept

The two points (0,0) and (3,-5) are on the straight line.

You can substitute a number in for x and compare the answer choices (not the most efficient way but it's how I would do it). Let's just say x = 5. Then the expression would equal 0.25819889. Substitute 5 in for x is the answer choices and see which one is the same.

A) simplified is 0.004 repeating

B) simplified is 0.25819889

C) simplified is 0.12

D) simplified is 1.341640786

We can see that B is the right answer

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.

[tex] \frac{12}{n} - 12[/tex]

Final answer:

An algebraic expression for '12 less than the quotient of 12 and a number z' is represented by the mathematical expression (12/z) - 12.

Explanation:

To write an algebraic expression for "12 less than the quotient of 12 and a number z," you need to understand how to translate the words into a mathematical expression. The quotient of 12 and a number z is written as 12/z. To represent 12 less than this quotient, you simply subtract 12 from it, thus the expression becomes (12/z) - 12.

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.

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.

Answer:

You should multiply the expression by [tex]\frac{\sqrt{13}-\sqrt{11}}{\sqrt{13}-\sqrt{11}}[/tex]

Explanation:

To rationalize any expression, you must multiply it by its conjugate. A conjugate is defined as a similar expression to the original one but with an opposite sign

This means that:

The conjugate of a + b would be a -  b

Now, the given expression is [tex]\frac{2}{\sqrt{13}+\sqrt{11}}[/tex]

Consider the denominator:

From the above, we can conclude that the conjugate of [tex]\sqrt{13}+\sqrt{11}[/tex] is [tex]\sqrt{13}-\sqrt{11}[/tex]

And, remember that we need to keep the value of the expression unchanged. This means that we must multiply both the numerator and the denominator by the same value

Therefore:

You should multiply the expression by [tex]\frac{\sqrt{13}-\sqrt{11}}{\sqrt{13}-\sqrt{11}}[/tex] in order to rationalize the denominator

Hope this helps :)

Answer:

[tex] \frac { \sqrt { 13 } - \sqrt { 11 } } { \sqrt { 13 } - \sqrt { 11 } } [/tex]

Step-by-step explanation:

We are given the following expression and we are to determine the expression that we need to multiply it with in order to rationalize the denominator:

[tex] \frac { 2 } { \sqrt { 13 } + \sqrt { 11 } } [/tex]

To rationalize its denominator, we must multiply it with its conjugate.

For the denominator of the given expression, its conjugate would be [tex] \sqrt { 13 } - \sqrt { 11 } [/tex].

So to rationalize the expression, we would multiply it with:

[tex] \frac { \sqrt { 13 } - \sqrt { 11 } } { \sqrt { 13 } - \sqrt { 11 } } [/tex]

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.
