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.

Answer:

The area would be 170 cubic inches.

Step-by-step explanation:

To find the area, use the area of a trapezoid formula.

A = (a + b)/2*h

Now input the values

A = (18 + 22)/2 * 8.5

A = 40/2 * 8.5

A = 20 * 8.5

A = 170

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%

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:

The answer is ⇒ x = 0.73244

Step-by-step explanation:

∵ 90^x = 27 ⇒ insert log in both sides

∴ [tex]log(90)^{x}=log(27)[/tex]

∵ 90 = 9 × 10 , 27 = 3³

∵ log(a)^b = b log(a)

∴ log(9 × 10)^x = x log(9 × 10)

∴ [tex]xlog(9*10)=log(3^{3})[/tex]

∵ log(a × b) = log(a) + log(b)⇒log(9 × 10) = log(9) + log(10)

∴ [tex]x[log(9)+log(10)]=3log(3)[/tex]

∵ log(10) = 1 , 9 = 3²

∴ [tex]x[log(3)^{2}+1]=3log(3)[/tex]

∴ [tex]x[2log(3)+1] = 3log(3)[/tex]

∴ x = (3log3)/[2log(3)+1]

∴ x = 0.73244

ANSWER

[tex]x \approx0.732[/tex]

EXPLANATION

The given exponential equation is

[tex] {90}^{x} = 27[/tex]

We take natural log of both sides

[tex] ln( {90}^{x} ) = ln(27) [/tex]

Recall and the following property of logarithms.

[tex] ln( {a}^{n} ) = n \: ln(a) [/tex]

This implies that;

[tex]x ln(90) = ln(27) [/tex]

Solve for x.

Answer: 5

Step-by-step explanation: The first piece of information that you need to know is that the product is the answer when two numbers are multiplied. Therefore, you need to multiply the two sets of numbers, and then subtract.

The formula will be:

(5 x 2) - (5 x 1)=

First, do what is inside the parentheses:

10 - 5=

And solve...

5

The expression for the calculation the difference of the products 5 and 2 and 5 and 1 is (5 x 2) - (5 x 1).

Addition (Finding the Sum; '+') Subtraction (Finding the difference; '-') Multiplication (Finding the product; '×' ) Division (Finding the quotient; '÷')

The first thing you should be aware of is that the result of multiplying two integers is the product.

The two sets of numbers must therefore be multiplied before being subtracted.

The Expression will be:

(5 x 2) - (5 x 1)

First, work on the brackets separately

(5 x 2) = 10

(5 x 1)= 5

So, (5 x 2) - (5 x 1)

= 10 - 5

=5

I think it’s D. But I’m not 100 sure

Answer:

22.5

30

37.5

Step-by-step explanation:

You have to multiply each ratio part by x to get them properly set up to add to  90.

3x + 4x + 5x = 90               Combine the left side

12x = 90                              Divide by 12

12x/12 =90/12                      Do the division

x = 7.5

3x = 3*7.5 = 22.5

4x = 4*7.5 = 30

5x = 5*7.5 = 37.5

Total             90

Final answer:

The lengths of the sides of the triangle with a perimeter of 90 cm and sides in the ratio 3:4:5 are 22.5 cm, 30 cm, and 37.5 cm. This is found by setting up an equation with variable x representing the common multiplier for the ratio, solving for x, and then calculating each side's length.

Explanation:

To solve the problem of finding the length of each side of a triangle with sides in the ratio 3:4:5 and a perimeter of 90 cm, we first set up an algebraic equation. Let the sides of the triangle be 3x, 4x, and 5x, respectively. The perimeter is the sum of these sides, so we have the equation 3x + 4x + 5x = 90 cm. Simplifying this gives us 12x = 90 cm. To find the value of x, we divide both sides of the equation by 12, resulting in x = 90 cm / 12, which simplifies to x = 7.5 cm. Subsequently, the lengths of the sides are 3x = 22.5 cm, 4x = 30 cm, and 5x = 37.5 cm.

Answer:

False

Step-by-step explanation:

To form a triangle, the sum of any two sides must be LARGER than the length of the third side.  

This question says the sum of two sides are equal to the length of the third side.  This wouldn't form a triangle.

Final answer:

Yes, the statement is true. If the sum of two congruent lengths is equal to the length of a third side in a triangle, then the triangle is isosceles.

Explanation:

Yes, the statement is true. If the sum of two congruent lengths is equal to the length of a third side in a triangle, then the triangle is isosceles.

In an isosceles triangle, two sides have the same length (congruent sides) and the remaining side is different (non-congruent side).

For example, if we have a triangle ABC where AB = BC (congruent sides) and AC is a different length (non-congruent side), then the triangle ABC is isosceles.

The actual dimensions of Jamal's property are 75 feet long and 60 feet wide.

If Jamal's scale drawing is 15 inches long and 12 inches wide, and one inch on the drawing represents 5 feet in real life, we can calculate the actual dimensions of the property.

Length of the property:

15 inches on the drawing represents 15 * 5 = 75 feet in real life.

Width of the property:

12 inches on the drawing represents 12 * 5 = 60 feet in real life.

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:

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]
