Answers
Answer:
89
Step-by-step explanation:
586 divide by 4 is 146.5 so then i rounded to make it 147 then subtracted the points she already had (58) which led me to 89
Answer:
132 questions
Step-by-step explanation:
First, let’s find how many more points she needs.
To find this, find the difference between the points she needs and the points she has.
points needed- points gained
She needs 586 points and already has 58 points.
586 points-58 points
528 points
Now, we need to find how many questions she needs to answer correctly.
She needs 528 points and every correct question is worth 4 points.
Therefore, we can divide 528 by 4 to find how many questions she must answer correctly.
528/4=132
132 questions
She must answer 132 questions correctly to pass the test.

If Maya makes 5 bracelets in 2/3 hours, then she can make approximately 11 bracelets in 1.5 hours.
How many bracelets can Maya braid in 1.5 hours?
Given the parameter:
Maya makes 5 bracelets in 2/3 hours.
How many can she make in 1.5 hours?
To determine the number of bracelets Maya can make in 1.5 hours, we can set up a proportion.
Let 'x' be the number of bracelets in 1.5 hours
(5 bracelets) / (2/3 hour) = (x bracelets) / (1.5 hours)
Solve for x:
x × 2/3 = 5 × 1.5
x × 2/3 = 5 × 3/2
x × 2/3 = 5 × 3/2
2x/3 = 15/2
2x × 2 = 3 × 15
4x = 45
x = 45/4
x = 11.25
x ≈ 11 bracelets
Therefore, she can make approximately 11 bracelets in 1.5 hours.

1) Write a linear function that represents your monthly income.
2) What is the slope? What does it mean in this context?
3) What is the y-intercept? What does it mean in this context?
4) BONUS (1 pt) If you sell $5,000 worth of product, what is your monthly income?
Answers
Answer:
1) y = 0.3x + 1000
2) slope = 0.3
The slope is the fraction of the monthly sales that is added to your salary.
3) y-intercept = 1000
The y-intercept is the fixed part of the salary, $1000.
4) The salary is $2500
Step-by-step explanation:
1)
monthly salary = fixed part + variable part
The fixed part is $1000. Every month you receive $1000 no matter the amount of sales.
The variable part varies according to the amount of sales. You get 30% of the of the monthly sales. Let the monthly sales be x. The variable part is 0.3x
Let the monthly salary = y.
y = 1000 + 0.3x
y = 0.3x + 1000
2)
slope = 0.3
The slope is the fraction of the monthly sales that is added to your salary.
3)
y-intercept = 1000
The y-intercept is the fixed part of the salary, $1000.
4)
In this case, x = 5000
y = 0.3x + 1000
y = 0.3(5000) + 1000
y = 1500 + 1000
y = 2500
The salary is $2500.
