The answer would be 25% or 1/4 if you wanted it in fraction form.

The percent of the students surveyed said their favorite food was pizza is 25%. You can simplify 10/40 by 10/10 which gives you 1/4. You then multiply 1/4 to a number that gives you ?/100, which would be 25/100. And that would give you 25%.

On a number line, the coordinates of j, k, l, m, n are −10.5, −4, −1, 1.5, 4 respectively. find the lengths of the two segments.
nordsb [41]

Answer:

  • JK = 6.5
  • KM = 5.5
  • not congruent

Step-by-step explanation:

JK = K-J = (-4) -(-10.5) = 6.5

KM = M -K = 1.5 -(-4) = 5.5

6.5 ≠ 5.5, so the segments are not congruent.

The length of a rectangle is 16 feet more than three times the width. The perimeter of the rectangle is 248 feet. Find the dimen
sattari [20]

Answer:

L = 97, w = 27

Step-by-step explanation:

The perimeter formula is P = 2L + 2w.  We have too many unknowns simply to plug in, so we have to find a way to identify one in terms of the other.  The statement is that the length is 16 feet more than 3 times the width, so the length is in terms of the width and can be identified as

L = 3w + 16

and the width, then, is just w.  Now we can fill in those 2 values, both in terms of w, and set it to equal the perimeter value we were given of 248:

2(3w + 16) + 2w = 248 and

6w + 32 + 2w = 248 and

8w + 32 = 248 and

8w = 216 so

w = 27

That means that the width is 27.  Use that value of w now to find the length where

L = 3w + 16.

L = 3(27) + 16 and

L = 97

The school production of​ 'Our Town' was a big success. For opening​ night, 392 tickets were sold. Students paid ​$3.00 ​each, w
elixir [45]

Answer:

<u>239 students and 153 non-students attended to the school production of "Our Town"</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Number of tickets of the school production sold = 392

Student ticket cost = US$ 3

Non-students ticket cost = US$ 5

Total collected = US$ 1,482

2. How many students and how many​ non-students attended?

For answering the question we will use the following equation:

x = Number of students that attended the school production

392 - x = Number of non-students that attended the school production

3x + (392 - x) * 5 = 1,482

3x + 1,960 - 5x = 1,482

-2x = 1.482 - 1,960

-2x = - 478

x = -478/-2

<u>x = 239 ⇒ 392 - 239 = 153</u>

<u>239 students and 153 non-students attended to the school production of "Our Town"</u>
