Eva has borrowed 150 songs from her friend. She plans to download an equal number of songs on her music player each week for 5 weeks. The graph shows the number of songs left to download, y, for a certain number of weeks, x:
A graph titled Song Downloading shows Number of Weeks on x-axis and Number of Songs Left to Download on y-axis. The x-axis scale is shown from 0 to 5 at increments of 1, and the y-axis scale is shown from 0 to 280 at increments of 40. A straight line joins the ordered pairs 0, 200 and 1, 160 and 2, 120 and 3, 80 and 4, 40 and 5, 0.
Part A: What is the rate of change and initial value of the function represented by the graph, and what do they represent in this scenario? Show your work to find the rate of change and initial value. (6 points)
Part B: Write an equation in slope-intercept form to model the relationship between x and y. (4 points)

Cincinnati is about 225 miles from Cleveland. What is the distance between these cities on the map?
10 millimeters = 25 miles
Answer:90
Step-by-step explanation:
The distance between these cities on the map is 90 mm.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Cincinnati is about 225 miles from Cleveland and on scale 10 millimetres is equal to 25 miles.
The distance on the map will be calculated as,
25 miles = 10 mm
1 mile = 10 / 25 mm
225 miles = ( 225 x 10 ) / 25
225 miles = 90 mm
Therefore, the distance between these cities on the map is 90 mm.

Answer:
y - 7 = - [tex]\frac{5}{2}[/tex] (x + 2)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - [tex]\frac{5}{2}[/tex] and (a, b ) = (- 2, 7 ) , then
y - 7 = - [tex]\frac{5}{2}[/tex] (x - (- 2) ) , that is
y - 7 = - [tex]\frac{5}{2}[/tex] (x + 2)

A school hall costs £200 to hire.
Parents get a 10% discount.
30 parents share the cost equally.
How much does each parent pay
Answer:
£6
Step-by-step explanation:
The computation of the each parent pay is shown below;
But before that the cost of hall after considering the discount is
= £200 - 10% of £200
= £200 - £20
= £180
Now there are 30 parents
So each parent pay is
= £180 ÷ 30 parents
= £6
A worker is paid Rs 1110 for 6 days. If he told wage during a month is Rs 4625, for how many days did he work?
Worker work for =25 days and he paid Rs.4625.

From the question,
Worker is paid Rs.1110 for =6 days
Worker is paid Rs.1 for =(6/110) days
Worker is paid Rs.4625 for =(6/1110)×(4625) days

Sumaya is using two different strings of Christmas lights to decorate her house.one string flashes every 10 seconds.the other one string flashes every 15 seconds.when Sumaya turns on the lights they flashes at the same time.work out how long it will be before they flash again at the same time.use the LCM to help you work out your answer
Answer: 30 seconds
Step-by-step explanation:
From the question, we are informed that one string flashes every 10 seconds while the other one string flashes every 15 seconds.
The number of minutes that it'll take before they both flash again at the same time will be gotten by calculating the LCM of 10 and 15. This will be:
10 = 10, 20, 30, 40, 50 ...
15 = 15, 30, 45, 60, 75 ....
We can see that the lowest common multiple of 10 and 15 is 30. Therefore, the answer is 30.
They'll both flash again at same time in 30 seconds.

Since you are adding all the sides, you multiply 20x2 because there are two sides. Then you multiply 13x2 because 6 plus the missing number in the bottom right corner is equal to 7. The answer that you get from the multiplications, you add them and you have your perimeter.
There are only 5 blue cards, 2 green cards and 4 red cards in a pack.
Isabella is going to take at random one card from the pack.
(a) Write down the probability that Isabella will take a blue card.
Answer:
5/11 or 45 percent, since there are 5 blue cards
The probability that Isabella will take a blue card is 5/11.
What is probability?Probability is the chance that something will happen, or how likely it is that an event will occur.
Formula for probabilityP(E) = total number of favorable outcomes/ total number of outcomes
Where,
P(E) is the probability of any event.
According to the given question
Five blue cards, two green cards and four red cards.
⇒ total number of outcomes = 5+ 2 + 4 = 11
For finding the probability of blue card
Total number of blue cards is 5.
⇒ total number of favorable outcomes = 5
Therefore,
The probability of getting blue card
= number of favorable outcomes/ total number of outcome
= [tex]\frac{5}{11}[/tex]
Hence, the probability that Isabella will take a blue card is 5/11.

A recipe calls for 1/4
cup of milk for every 1 1/2
cups of flour. How many cups of flour will you need for 1/2
cup of milk?
Answer:
3 cups flour
Step-by-step explanation:
set up a proportion and cross-multiply:
1/4 = 1/2
3/2 f
1/4f = 3/4
4f = 12
f = 3
Answer:
3 cups
Step-by-step explanation
basically if 1/4 cup of milk is for 1 1/2 cups of flour ------ 1/2 cup is twice the amount that a quarter cup is because a 1/4 cup + a 1/4 cup = 1/2 cup so you double the amount of flour too and 1 1/2 + 1 1/2 is 3 cups of flour.
1/4 + 1/4 = 1/2 (milk)
1 1/2 + 1/12 = 3 (flour)
