a. What is the constant of proportionality for the relationship between
pages and days?
b. Write an equation to show the relationship between pages and days.
Answers
Answer:
a). k = 0.75
b). y = 0.75x
Step-by-step explanation:
a). Graph is showing the relation between number of pages (P) illustrated by Indira and number of days taken (D).
P ∝ D
P = kD
Where 'k' is the proportionality constant.
k = [tex]\frac{P}{D}[/tex]
From the graph attached,
For a point with ordered pair (2, 1.5),
k = [tex]\frac{1.5}{2}[/tex]
k = 0.75
b). Equation representing the relation between number of pages and number of days will be,
P = 0.75D
y = 0.75x
There were 28 boys on the boy's basketball team and 16 girls on the girl's basketball team last year. This year the number of boys decreased by 8% but the number of girls increased by 19%. Was there an increase or decrease in overall participation?
Answers
The sum of participants last year was 44 students, but this year was only 37.80 participants.
There is an increase in total participants.
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
number of boys = 28
Number of girls = 16
Total participants = 28 + 16 = 44
Now, there is decrease in number of boys by 8%
= 28- 8% x 28
=28- 8/100 x 28
=28 - 0.08*28
=28 -2.24
= 25.76
and, there is 19% increase in number of girls
=16 + 0.19 x 16
=16 + 3.04
=19.04
So, total participants = 25.76 + 19.04
= 44.8
Hence, there is an increase in total participants.

Amy sold 10 t-shirts and 2 sweatshirts for $56.
Adam sold 5 t-shirts and 3 sweatshirts for $48.
Write a system of equations to represent this
situation. Let x=cost of a t-shirt and y=cost of a
sweatshirt.
Determine the price of one t-shirt and the price
of one sweatshirt.
Answers
Answer:
$3.6 = cost of a t-shirt
$10 = cost of a sweatshirt
Step-by-step explanation:
Given:
10 t-shirts and 2 sweatshirts = $56.
5 t-shirts and 3 sweatshirts = $48.
x = cost of a t-shirt
y = cost of a sweatshirt
Find:
Price
Computation:
10x + 2y = 56.......eq1
5x + 3y = 48........eq2
From 2 x eq2
10x + 6y = 96.........eq3
From eq3 - eq1
4y = 40
y = 10
from eq1
10x + 2(10) = 56
10x + 20 = 56
10x = 36
x = 3.6
$3.6 = cost of a t-shirt
$10 = cost of a sweatshirt

When as rate, 100 miles in 5 hours would be ????? miles per hour
Answers
Answer:
20
Step-by-step explanation:
5 divided by 100 = 20
Answer:
20 miles per hour (20 mi/h)
Step-by-step explanation:
100 miles/5 hours = 20 miles/ 1 hour
(simplify the proportion)
Consider the following formula s=d/t, with
s being the speed, d as the distance, and t as the time.
this is because miles per hour is a measurement of speed.
In this case, 100 miles is the distance. 5 hours is the time, and we are solving for s.
s = 100/5, s = 20/1, s = 20 which is 20. So the rate or the speed is 20 miles per hour.
Anything multiplied or divided by 1 will remain the same.

We can tell that the whole L shaped angle is 90 degrees because it has the little box in the corner. Now, the 90 degree angle is split into two parts with that line coming from the box. Those two parts of the whole 90 degree angle add up to 90 degrees.
90 = 4v + 2 + 9v - 3
Now, let's solve for v. Combine like terms.
90 = 13v - 1
Add 1 to both sides.
91 = 13v
Divide both sides by 13
7 = v

|8x+3|=12 what’s the answer
Answers
Answer:
x= 9/8 , -15/8
Step-by-step explanation:
Answer:
x = 1.125 , x = 9/8
Step-by-step explanation:
|8x+3| = 12
=> 8x + 3 = 12
=> 8x = 12-3 = 9
=> 8x = 9
=> x = 9/8
As 9/8 is a fraction let's make it a decimal.
9/8 * 125/125 (To make it into a power of ten so that we can convert)
=> 1125 / 1000
=> 1.125
