Jessie's school has 570 students. Thirty percent of the students are eighth-graders. One-third of eighth-graders walk to school. How many eighth-graders walk to school?

Answers

Answer 1

Answer:

57

Step-by-step explanation:

10% of 570 = 57 (dividing by 10). Times that by 3, which is 171. Now divide 171 by 3, equals 57 (the answer).

solve for the value of k

Answers

Answer:

k = 42

Step-by-step explanation:

This is a complementary angle, meaning that the angles formed equal 90 degrees. We know it is complementary because the angle is shown was a tiny square, a sign that it is 90 degrees. Thus, the two angles (k+1) and 47 added together must equal 90. So, we can write an equation:

(k+1) + 47 = 90

k + 1 = 43

k = 42.

K=42
So (42+1)=43 2*43=86 (86+4)=90

If (X+2,4) and (5,y-1 are equal ordered pairs ,Find the value of X and y​

Answers

Answer:

x = 3, y = 5

Step-by-step explanation:

Since the ordered pairs are equal, then equate the x and y coordinates

x + 2 = 5 ( subtract 2 from both sides )

x = 3

y - 1 = 4 ( add 1 to both sides )

y = 5

A rectangle has a length that is twice the width. The width is to be extended by 5 ft and the length by 3 ft, so the total area becomes 99 square feet. What was the original length?

Answer Choices:
4 ft
6 ft
8 ft
10 ft
12 ft
14 ft
16 ft

Answers

Answer:

8 feet

Step-by-step explanation:

w = width

2s = length

Find 'w' by multiplying the new dimensions:

(w+5)(2w+3) = 2w² + 3w + 10w + 15 = 99

simplify:

2w² + 13w - 84 = 0

Factor:

(2w + 21)(w - 4) = 0

w = -21/2   ** disregard because a measurement cannot be negative **

w = 4

original width was 4

orginal length was twice 4 or 8 feet

Why is it important to know how to use area or volume in real life?

Answers

It’s important because you may doing something that includes that and you don’t have a ruler etc..
The concepts of area and volume all talk about how much space a 2D or 3D figure occupies. In real life, there are certain jobs that include measuring and geometry, which you will be able to accomplish by your math skills. For example, engineering involves analyzing and modeling certain objects. Even if work is not included, the daily activities we do, sometimes include area and volume. Such as finding a gift box where your gift perfectly fits and measuring your daily water intake.

Which graph fits this line? y = 2x + 1

Answers

Answer:

Calculating two points and drawing the line between the two.

Explanation:

To find the y-intercept, put x = 0

y = 2 (0) - 1

y = -1

To find the x-intercept, put y = 0

2x - 1 = 0

2x = 1

x = 1/2

Draw your system of axis. Mark -1 on the y-axis, and 1/2 on the x-axis.

Now draw a line through these two ponts. Add arrows.

==============================================

To draw the graph by using points,

let x = -1, then y = 2 (-1) - 1 = -2 - 1 = -3

first point is (-1; -3)

Let x = 0, y = 2 (0) - 1 = -1

Second point is (0; -1)

Let x = 1, y = 2(1) - 1 = 1

Third point is (1; 1)

Plot the three points and draw a line through them. Add arrows to your line.

tickets must be sold?

A-less than 10 tickets
B-15 adult tickets
C-at least 19 adults tickets
D-no more than 8 adult tickets

Answers

$5 x 20 = 100

$7.50 x 19 = 142.5

100 + 142.5 = 242.5

The answer is C, at least 19 adult tickets.
You get the closest answer to 240 by answering C.

Answer:

C

Step-by-step explanation:

the theater sold 20 discount tickets=5*20=100$

Two equations are given. m + 5n = 20
m = n-4

What is the solution to the set of equations in the form (m, n)?

A (3,7)
B (0,4)
C (5, 1)
D (2,6)

Please help

Answers

Answer:

B. (0, 4)

Step-by-step explanation:

so we need to find the value of m and n, and luckily we have 2 equations that'll help. (I'm going to use the substitution method for this instead of the Elimination method because I am lazy)

first we need to solve for m, but we already have an equation that tells us what m is equal to, m = n - 4.

now we just need to plug in our new m into the other equation and solve for n. (we are using m + 5n = 20 for that)

so now we get

(n - 4) + 5n = 20

so we solve for n

n + 5n = 24

6n = 24

n = 4

now that we know that n is 4, we can plug that into our m equation (m = n - 4)

m = 4 - 4

m = 0

now we have our m and n, and we can make our ordered pair.

(m, n)

(0, 4)

Use substitution to solve the system of equations.

Which side lengths form a right triangle? Choose all that apply. 5, the square root of 8, 33 or 8,15,17 or the square root of 2, the square root of 2, 2

Answers

Answer:

17² = 15² + 8²

2² = (√2)² + (√2)²

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. There are different types of triangles such as right angled, acute, obtuse and isosceles triangle.

In right angle triangle, one angle is 90°. From Pythagoras theorem, the square of the longest side (hypotenuse) is equal to the sum of the square of the two sides. Hence:

33² ≠ (√8)² + 5² (not right triangle)

17² = 15² + 8² (right triangle)

2² = (√2)² + (√2)² (right triangle)
