Answer 1

Answer:

Multiple Choice: 2 Points Each

Short Response: 4 Points Each

Step-by-step explanation:

This is a system of equations problem.

The way I solved it was by, first, organizing two equations.

m(23)+s(10)=86 and m(28)+s(5)=76

m = multiple-choice question points

s = short response question points

The first equation is your scores. m(23)+s(10)=86

You had 23 multiple choice questions and 10 short response questions. Your score on the test was 86.

The second equation is your friend's score. m(28)+s(5)=76

They had 28 multiple choice questions and 5 short response questions. They scored a 76 on the test.

Solve m(23)+s(10)=86;m(28)+s(5)=76

23m+10s=86 for m

Add -10s to both sides.

23m+10s+−10s=86+−10s

23m=−10s+86

Divide both sides by 23.

[tex]\frac{23m}{23}=\frac{-10s+86}{23}[/tex]

m=[tex]\frac{-10}{23} s+\frac{86}{23}[/tex]

Substitute [tex]\frac{-10}{23} s+\frac{86}{23}[/tex] for m in 28m+5s=76.

28m+5s=76

28( [tex]\frac{-10}{23} s+\frac{86}{23}[/tex])+5s=76

Simplify both sides of the equation.

[tex]\frac{-165}{23} s+\frac{2408}{23} =76[/tex]

Add [tex]\frac{-2408}{23}[/tex] to both sides.

[tex]\frac{-165}{23} s+\frac{2408}{23} +\frac{-2408}{23} =76+\frac{-2408}{23}[/tex]

[tex]\frac{165}{23} s=\frac{-660}{23}[/tex]

[tex]\frac{\frac{-165}{23}s}{\frac{-165}{23}}=\frac{\frac{-660}{23}}{\frac{-165}{23}}[/tex]

s=4

Substitute 4 for s in m=[tex]\frac{-10}{23}s+\frac{86}{23}[/tex]

m=[tex]\frac{-10}{23}s+\frac{86}{23}[/tex]

m=[tex]\frac{-10}{23}(4)+\frac{86}{23}[/tex]

Simplify both sides of the equation.

m=2

Answer:

m=2 and s=4

An artist receives royalties for all digital downloads of his music. For the first 10,000 downloads, the artist receives $10,000. He receives $12,500 for the next 10,000 downloads, $15,000 for the next 10,000 downloads and so on. How much money will he receive if his music is downloaded 500,000 times?

Answers

Answer:

Step-by-step explanation:

This is a linear relationship. We know this because as the number of songs increases by 10,000 the amount of money increases $2500. We can use that relationship in a proportion, which is a method used to solve problems involving directly proportional numbers.

If we arrange our information such that the dollars earned are on the top of the fraction and the number of songs that need to be downloaded to earn that amount of money is on the bottom of the fraction, here is what we have:

[tex]\frac{2500}{10,000}[/tex]. This means that the artist receives $2500 for every 10,000 downloads. Keeping in that pattern, we can find out how much money he will earn when 500,000 downloads are completed, assuming that the amount he earns per 10,000 songs doesn't change.

[tex]\frac{2500}{10000}=\frac{x}{500000}[/tex] and cross multiply to get

10,000x = 1250000000 and divide to get

x = 125,000

That is the amount that he will earn from 500,000 downloads.

volume=15×5×5+8×4×5+8×4×5

=375+160+160

=695 m³

Answer:

695 m^3

Step-by-step explanation:

With this object, there are three rectangular prisms. The equation to find the volume of them is L*W*H.

So, with the small one in the front, the sides are 8, 4, and 5, so do:

8*4*5 ---> 160

Next, with long middle one, the sides are 5, 5, and 15, so do:

5*5*15 --->375

Then, with small one in the back, 8, 4, and 5 again, so do:

8*4*5 ---> 160

To finish it off, add them all together.

160 + 375 + 160 = 695 m^3

Answer:

The circumference of circle is 31.4 cm

What is circumference of circle?

"It is the distance around the perimeter of a circle."

Formula for circumference of circle:

"C = 2 × π × r,

where r is the radius of the circle."

For given question,

We have been given the radius of a circle.

r = 5 cm

We need to find the circumference of circle.

Using the formula for circumference of circle,

⇒ C = 2 × π × r

We need to use π = 3.14

⇒ C = 2 × 3.14 × 5

⇒ C = 2 × 5 × 3.14                        ...............(since  a × (b × c) = (a × b) × c)

⇒ C = 10 × 3.14

⇒ C = 31.4 cm

This means, the circumference of circle having radius r = 5 cm

is C = 31.4 cm

Therefore, the circumference of circle is 31.4 cm

Find the missing angle measures. This is 8th grade math btw

Answers

Answer:

w is 146

x is 90

y is 34

z is 56

Answer:

w = 146 degrees

x = 90 degrees

y = 34 degrees

z = 56 degrees

Step-by-step explanation:

Right angles will always add up to 90 degrees.

Straight lines will always add up to 180 degrees.

Since x is a right angle, x = 90 degrees.

Since z + 34 = 90 degrees (a right angle):

90 - 34 = z

90 - 34 = 56 degrees

Since x + y + z = 180 degrees (a straight line), simply plug in the numbers we have found already:

90 + y + 56 = 180

y = 180 - 90 - 56

y = 34

Since w + 34 = 180 degrees (a straight line):

180 - 34 = w

180 - 34 = 146 degrees

Which pair of equations below is a result of constructing the altitude, h, in traingle ABC?

Answers

Answer:

sinA = h/c; sinC = h/a

Step-by-step explanation:

Which pair of equations below is a result of constructing the altitude, h, in Triangle ABC?

sinA= h/c

sinC= h/a

sinA= h/c

sinB= b/c

sinA= b/c

sinC= b/a

Solution:

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.

In right triangle, trigonometric identities are used to show the relationship between the sides of a triangle and the angles.

sinθ = opposite / hypotenuse, cosθ = adjacent / hypotenuse, tanθ = opposite / adjacent

Therefore in triangle ABC:

sinA = h/c;  sinC = h/a

Answer:

Flashlight ;  = $2.99

Water bottle = $1.50

Toothbrush = $1.29

Compass = $3.29

Step-by-step explanation:

Sales tax = 7%

Item: _____ price

Flashlight ;  = $3.20

Water bottle = $1.61

Toothbrush = $1.38

Compass = $3.52

Total cost = price of item + sales tax

Sales tax = 7%

Total cost = (1 + 7%) * price of item

Total cost = (1 + 0.07) * price of item.

Total cost = 1.07* price

Flashlight = 1.07*1.29 = $3.20

Water bottle = 1.07*1.50 = $1.61

Toothbrush = 1.07*1.29 = $1.38

Compass = 1.07*3.29 = $3.52
