Answers

Answer 1

Answer:

x = 10

I used the Interior Angles of a Triangle Rule --The sum of all 3 interior angles in a triangle is always 180°.

(3x + 28) + (5x - 18) + 90° = 180°

Now i can get rid of the parentheses and combine like terms.

3x + 5x + 28 - 18 + 90 = 180

8x + 10 + 90 = 180

8x + 100 = 180

Then i subtract 100 from both sides to isolate x.

8x + 100 - 100 = 180 - 100

8x = 80

Then, i divide both sides by 8 to find x.

8x ÷ 8 = 80 ÷ 8

x = 10

What's the perimeter of (-9,8) (-9,16) and (-17,8)

Answers

Answer:

16 + sqrt(128)

Step-by-step explanation:

find the lengths of all 3 sides:

the side from (-9,8) to (-9,16) will be 16-8=8 (x stays constant)

The side from (-9,8) to (-17,8) is 8 (-9- (-17)=8)

The side from (-9,16) to (-17,8) will be found from the distance formula

d=sqrt((-17-9)^2 + (8-16)^2))

= sqrt(128)

So the perimeter will be these 3 numbers added together

P=sqrt(128) + 8 + 8

= 16 + sqrt(128)

which can simplify to:

= 16 + 4sqrt(8)

= 16 + 8sqrt(2) = 8+ sqrt(2)

Select the correct answer. A sound wave enters a new medium where sound travels faster. How does this affect the frequency and wavelength of the sound? A. The frequency increases and the wavelength decreases. B. The frequency decreases and the wavelength increases. C. The frequency stays the same and the wavelength increases. D. The frequency stays the same and the wavelength decreases. E. Neither the frequency nor the wavelength is affected.

Answers

Answer:

The correct answer is E. Neither the frequency nor the wavelength is affected. Explanation: The wave frequency does not affect the speed of that wave. An increase in frequency of a wave causes a decrease in wavelength while the wave speed remains the constant. The speed of the waves is significantly higher at higher tensions.

1.) Band A charges $800 to play for the evening and Band B charges $450 plus $1.25 per student.
a. Write a system of equations to represent the costs of the two bands. Use y for total cost and use x for
number of students.
Band A

Answers

Answer:

[tex]y = 800[/tex] ---- Band A

[tex]y = 450 + 1.25x[/tex] --- Band B

Step-by-step explanation:

Given

Band A:

[tex]Charges = \$800[/tex] per student

Band B:

[tex]Charges = \$450[/tex]

[tex]Rate = \$1.25[/tex] per student

Required

Write an equation for the system?

For band A, the given charges is irrespective of number of students.

So, the total cost y is:

[tex]y = 800[/tex]

For band B, the total y is calculated as thus:

y = Base Charges + Rate * Number of students (x)

[tex]y = 450 + 1.25 * x[/tex]

[tex]y = 450 + 1.25x[/tex]

So, the charges for the bands are:

[tex]y = 800[/tex] ---- Band A

[tex]y = 450 + 1.25x[/tex] --- Band B

If you are driving 30 miles per hour, how far will you go in 5 hours? To solve this problem, all you need to do is multiply your rate by 5. Remember to multiply both the numerator and denominator by the same number.

30 miles/1 hour × 5/5 = 150 miles/5 hours.

You will drive 150 miles in 5 hours. Don’t forget to label your answer with the correct units!

evaluate -6(7/6)+2(1/3)=

Answers

-6.333333... OR -19/3

In the problem: -6(7/6) + 2(1/3) Let's only worry about the left of the equal sign for now.

-6(7/6) we have to simplify this. So what we do is we multiply -6(7) and leave the denominator the same so -6(7/6) is -7.

Now we simplify the right part of this problem.

2(1/3) just like the 1st time, we have to simplify this. So what we do is we multiply 2 and 1 together and leave the denominator the same. So, 2(1) is 2 and leave the denominator the same so the answer is 2/3

Now add them together.

-7 + 2/3 = 6.333...

To the nearest millimeter, a cell phone is 105 mm long and 66 mm wide. What is the ratio of the width to the length?

Answers

Answer:

22:35

Step-by-step explanation:

Find the GCD (or HCF) of numerator and denominator

GCD of 66 and 105 is 3

Divide both the numerator and denominator by the GCD

66 ÷ 3/105 ÷ 3

Reduced fraction:

22/35

therefore the ratio will be 22:35

Johannes needs to buy replacement team uniform and is looking at different prices. He has a budget of $300. He needs 18 pairs of pants and 12shirts. Let x represent the cost of each pairs of pants, and y represent the cost of each shirt. Which graph correctly shows the cost of the pants and shirts johannes can buy, if no tax is added?

Answers

Answer:

Step-by-step explanation:

The graph that shows the cost of the pants and shirts Johannes can buy, is a linear graph

The budget is given as

[tex]\mathbf{Budget = 300}[/tex]

If x represents the cost of each pair of pants.

Then the amount spent on 18 pairs of pants is:

[tex]\mathbf{Pants = 18x}[/tex]

If y represents the cost of each shirt.

Then the amount spent on 12 shirts is:

[tex]\mathbf{Shirt= 12y}[/tex]

So, the equation is:

[tex]\mathbf{Shirts + Pants =Budget}[/tex]

Substitute known values

[tex]\mathbf{18x + 12y =300}[/tex]

Divide through by 6

[tex]\mathbf{3x + 2y =50}[/tex]

See attachment for the graph of [tex]\mathbf{3x + 2y =50}[/tex]

A.Their intersection point is the only point where the same input into both functions yields different outputs.
B.Their intersection point is the only point where different inputs into both functions yield different outputs.
C. Their intersection point is the only point where different inputs into both functions yield the same output
D. Their intersection point is the only point where the same input into both functions yields the same output.

Answers

Answer:

D. Their intersection point is the only point where the same input into both functions yields the same output.

Step-by-step explanation:

The intersection point of 2 graphed lines represents the solution.

At this point, for both lines, there is the same x value (input) and the same y value (output) because both of the lines have that point in common.

So, if those 2 lines were to be graphed, the intersection point would represent the only point with the same input and output for both functions.

D is the correct answer.
