Brayden signed up for a streaming music service that costs $11 per month. The service allows Brayden to listen to unlimited music, but if he wants to download songs for offline listening, the service charges $1 per song. How much total money would Brayden have to pay in a month in which he downloaded 35 songs? How much would he have to pay if he downloaded s songs?

Answers

s = # of songs

y = total amount of money

$11 + $1(35) = y

Simplify the right side

$11 + $35 = y

Combine like terms

$46 = y

If he downloaded 35 songs, he would have ti pay $46

If he downloaded s amount of songs, he would have to pay $11 + $1s = y

Consider the experimental situation described below. Ability to grow in shade may help pines in the dry forests of Arizona resist drought. How well do these pines grow in shade? Investigators planted pine seedlings in a greenhouse in either full light or light reduced to 5% of normal by shade cloth. At the end of the study, they dried the young trees and weighed them. Identify the experimental unit(s) or subject(s). (Select all that apply.)

Answers

Answer:

Pine tree seedlings

Step-by-step explanation:

An experimental unit refers to the subject or factor under investigation. The subject or factor is subjected to different treatments in the course of the study. In the case of the experimental situation described above, the pine tree seedlings are the experimental units that actually received the treatments.

The treatments included being subjected to full or reduced light in the greenhouse. The response of the seedlings to these treatments would determine the outcome of the study.

2 The temperature in Chicago was - 10 degrees Fahrenheit. It then rose 5 degrees.

a. Write an equation that you can use to find the new temperature.

b. What is the new temperature?

C. Is your answer a positive or negative integer? Why?

Answers

Answer:

Step-by-step explanation:

Given

Initial Temperature = -10

Increment = 5

Required

Solving (a): Write an Equation

The equation is to add the initial temperature and the increment

i.e

Equation = Initial Temperature + Increment

Solving (b): Solve the equation

Substitute values for initial temperature and the increment

Result = -10 + 5

Result = -5

Solving (c):

It's a negative answer because the increment in temperature is not greater than the initial temperature

Jesper Co begins its next year of operations with a Beginning Supplies balance of 1,400. The end of period count of inventory revealed an Ending Supply balance of 4,500. If COGS for the same period was 36,700, Purchases must have been what? 0 33.600 35.300 39.800 36.700​

Answers

Answer:

Purchases= $39,800

Step-by-step explanation:

Giving the following information:

Beginning Supplies= 1,400

Ending Supply balance= 4,500

COGS= 36,700

To calculate the purchases, we need to use the following formula:

Purchases= COGS + desired ending inventory - beginning inventory

Purchases= 36,700 + 4,500 - 1,400

Purchases= $39,800

What is simplification?

Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.

The equation is given below.

[tex]x = \dfrac{5 + \sqrt{-49}}{6}[/tex]

We know that √(-1) = i, then we have

x = 5/6 + (√49 / 6)i

x = 5/6 + (7/6)i

Then the correct option is C.

There are 3 circles that indicate -1, so these are -3.

Insert as an expression:

On the right:

There are 2 triangles that indicate -x, so this is -2x.

There are 2 circles that indicate -1, so these are -2.

Insert as an expression:

Combine both expressions into an equation:

Karina and Perry are cleaning up litter in the park for community service hours. Karina and Perry both claim they have covered the greatest area. Who is correct? Justify your answer using mathematical reasoning.

Answers

Answer:

Perry's claim is correct while Karina is incorrect

Step-by-step explanation:

Question is incomplete (See Attachment)

First, we need to determine the area covered by Karina and Perry

For Karina, there are 9 square boxes each of which has an area of 1 unit sq

So:

[tex]Karina = 9 * 1\ unit^2[/tex]

[tex]Karina = 9\ unit^2[/tex]

For Perry:

There are 18 square boxes, each of which has an area of 1 unit sq.

So:

[tex]Perry = 18 * 1\ unit^2[/tex]

[tex]Perry = 18\ unit^2[/tex]

Comparing both areas, we can conclude that Perry's claim is correct while Karina is incorrect

How many kilograms of chocolate will each person if four people share 1/3 of a kilogram of chocolate equally?

Answers

Answer:

Each person would eat 83 grams of chocolate, which is equal to 0.083 kilograms.

Step-by-step explanation:

To determine how much chocolate each person will eat if 4 people divide 1/3 kilogram of chocolate, the following calculation must be made:

1/3 = 0.333

0.333 / 4 = 0.083

0.08 x 1000 = 83 grams

Therefore, each of the 4 people will eat 83 grams of chocolate.
