A bunch of students were on a field trip. Thirty percent of the students bought t-shirts for souvenirs. If 15 students bought t-shirts, how many students went on the trip? *

Answers

Answer 1

Answer: 50 students

Step-by-step explanation:

Let the number of students who went on the trip be x

The information given in the question can be formed into an equation as:

30% of x = 15

30/100 × x = 15

0.3 × x = 15

0.3x = 15

x = 15/0.3

x = 50

50 students went on the trip

here is an example jy26903

Answers

Answer:

I meant an example for a problem like the one you posted.

Either way, I'll try to help.

in the example, you're finding out what percentage of 352 is 226.6.

So divide 226.6 (The number that you're using to find what percentage it is of 352) by 352( the number you're finding the percentage of.)

226.6/352= 0.64375, and multiply the quotient by 100 to get 64.375. You're rounding up by the nearest hundredth, so the 7 turns to 8. (5 or more means rounding up.)

your final answer for the example is 64.38%. So Try that with your next problem.

For the one you're working on, divide 110.9 by 100 and then multiply it by 419.

You'll get 464.671.

Jane sold a house for $160,000 that she listed. Her broker charges a % commission and she receives 60% of the commission. How much did Jane receive?

Answers

Jane gets 5,760.

What is commission?

Commissions are a form of variable-pay remuneration for services rendered or products sold.

Given:

House sold for $160,000 with a listing commission of 6%

So, full commission

=160,000*0.06

= 9, 600

And, jane's share will be

=9600 * 0.60

=5,760

Hence, jane's share will be 5,760.

(a) Find an angle between 0° and 360° that is coterminal with 1020

Answers

Answer:

300°

Step-by-step explanation:

Subtract 360° from 1020° and repeat until angle is in required range

1020° - 360° = 660°, then

660° - 360° = 300°

300° is coterminal with 1020°

An angle between 0° and 360° that is coterminal with 1020° is 300°.

What are Coterminal angles?

Coterminal angles are defined as the angles which has the same terminal side with the initial side on the positive side of X axis.

We have to find an angle between ° and 360° that is coterminal with 1020°.

Subtract 360° from the given angle until the angle obtained is between 0° and 360°.

1020 - 360 = 660

660 - 360 = 300

So 300° is a coterminal angle with 1020.

Hence the coterminal angle is 300°.

What expressions are equivalent to y4 - 625?

Answers

Answer:

option D

Step-by-step explanation:

a² - b² = (a + b) (a - b)

625 = 5 * 5 * 5 * 5 = 5⁴

y⁴ - 625 = y⁴  - 5⁴

             = (y²)² - (5²)²           {a = y² ; b = 5²}

            = (y² + 5²)(y² - 5²)

           = (y² + 25)(y² - 5²)

           = (y² + 25)(y + 5)(y - 5)

factoring trinomials 6n^2-56n-40

Answers

Answer:

Step-by-step explanation:

Use the Quadratic Formula to find the roots, i.e., the values of n for which 6n²-56n-40 = 0.

Answer:

2(n - 10)(3n + 2)

Step-by-step explanation:

Given

6n² - 56n - 40 ← factor out 2 from each term

= 2(3n² - 28n - 20) ← factor the quadratic

Consider the factors of the product of the n² term and the constant term which sum to give the coefficient of the n- term.

product = 3 × - 20 = - 60 and sum = - 28

The factors are - 30 and + 2

Use these factors to split the n- term

3n² - 30n + 2n - 20 ( factor the first/second and third/fourth terms )

= 3n(n - 10) + 2(n - 10) ← factor out (n - 10) from each term

= (n - 10)(3n + 2)

Thus

6n² - 56n - 40 = 2(n - 10)(3n + 2)

Answers

Note how going from R to S to T to U has us going counterclockwise. In contrast, going from R' to S' to T' to U' has us going the opposite direction going clockwise. This change in orientation strongly implies that a reflection has been done. Reflections always flip orientation.

-----------------------------------------

Here's how we can find the line of reflection.

Draw a line segment from point R to point R'. Mark the midpoint of the segment as point A

Repeat this process to form a segment from S to S'. Mark the midpoint as point B.

The line of reflection will pass through points A and B. This is because the line of reflection is equally distant between the original point (such as point R) and its reflected point (such as R'). This must mean that the line of reflection goes through the midpoint of segment UU' and also segment TT'.

Jada is 3 feet 11 inches tall. A giraffe at the zoo is 16 feet 10 inches tall.
How much taller is the giraffe than Jada?
What’s the answer?

Answers

Answer:

12 feet 11 inches

Step-by-step explanation:

The giraffe is 12 feet 11 inches taller than Jada. Therefore, the correct answer is option C: 12 feet 11 inches.

To find out how much taller the giraffe is than Jada, we need to subtract Jada's height from the giraffe's height.

Jada's height is 3 feet 11 inches, which can be written as 3' 11".

The giraffe's height is 16 feet 10 inches, which can be written as 16' 10".

To perform the subtraction, we need to ensure both measurements are in the same format. We can convert Jada's height to inches:

Jada's height = 3 feet * 12 inches/foot + 11 inches = 36 inches + 11 inches = 47 inches.

Now we can subtract Jada's height from the giraffe's height:

16' 10" - 3' 11" = 16 * 12 + 10 - (3 * 12 + 11) = 192 + 10 - (36 + 11) = 202 - 47 = 155 inches.

Therefore, the giraffe is 155 inches taller than Jada.

To convert this back to feet and inches, we have:

155 inches = 12 feet * 12 inches/foot + 11 inches = 12' 11".

Thus, the giraffe is 12 feet 11 inches taller than Jada. Therefore, the correct answer is option C: 12 feet 11 inches.

A rancher is going to fence three sides of a corral next to a river. He needs to maximize the corral area using 240 feet of fencing. The quadratic equation A(x)=x(240−2x) gives the area of the corral, A, for the length, x, of the corral along the river. Find the length of the corral along the river that will give the maximum area, and then find the maximum area of the corral.

Answers

Answer:

A. 60 feet B. 7200 ft²

Step-by-step explanation:

A. Find the length of the corral along the river that will give the maximum area

To find the length of the corral that will give the maximum area, we differentiate A with respect to x and equate it to zero.

So, dA(x)/dx = d[x(240 - 2x)]/dx

= (240 - 2x)dx/dx + xd(240 -2x)/dx

= 240 - 2x -2x

= 240 - 4x

So, dA(x)/dx = 0

240 - 4x = 0

4x = 240

x = 240/4

x = 60 feet

B. Find the maximum area of the corral

The maximum area at x = 60 feet is

A(x)=x(240−2x)

A(60)=60(240−2(60))

A(60) = 60(240 - 120)

A(60) = 60(120)

A(60) = 7200 ft²

Answer:

maximum: 7200 sq ft.  60 ft along the river

Step-by-step explanation:

The maximum area of 7,200 square feet is reached when the corral has a length of 60 feet along the river.
