Answer:
y = -240
Step-by-step explanation:
If y varies jointly as x and z, then y/(xz) = k where k is the constant of proportion
60/10(-3) = 60/-30 = -2 = k
Now, y/(xz) = -2
y/8(15) = -2
y/120 = -2
y = -240

Linear
Exponential
Quadratic
2. What type of function can be used to model the scenario?
Jack adds 2 quarters to his piggy bank each week.
Linear
Exponential
Quadratic
Answer:
1. Exponential
2. Linear
Step-by-step explanation:
1. Exponential
Principal = 15000
Rate, r = 6.5% compounded annually
A = P(1 + r)^t
A = 15000(1 + 0.065)^t
A = 15000(1.065)^t
2. Linear
Let initial amount in bank = x
Amount added per week = 2
Number of weeks or period = t
A = x + 2t
If x and y vary inversely and x = 1 when y = 11, find x when y = 5.5.
Answer:
If the variable Y being 5.5 it's because she was divisible by two. So if I divise X by 2 the reply is 0.5. So at least if y is 5.5, x is 0.5.

7 plus a number z is more than 5
Answer:
z > -2
Step-by-step explanation:
7 + z > 5
subtract 7 from each side of the equation:
z > -2
The inequality for the given phrase is z+7>5.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The given phrase is "7 plus a number z is more than 5".
Here, 7 plus a number z is
7+z
The obtained sum is more than 5.
That, is z+7>5
Subtract 7 on both the sides of an inequality, we get
z+7-7>5-7
z>-2
Therefore, the inequality is z+7>5.

Answer:
a = [tex]\frac{12}{\sqrt{3} }[/tex]
Step-by-step explanation:
Using the tangent ratio in the right triangle and the exact value
tan30° = [tex]\frac{1}{\sqrt{3} }[/tex] , then
tan30° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{a}{12}[/tex] = [tex]\frac{1}{\sqrt{3} }[/tex] ( cross- multiply )
a × [tex]\sqrt{3}[/tex] = 12 ( divide both sides by [tex]\sqrt{3}[/tex] )

1) Gary makes $15.00 per hour for a five-day
forty-hour work week. Also, he makes double-
time for holidays. This week, he works three
regular days and two holidays. What will be his
paycheck for this week?
A) $$40
B) $850
C) $860
D) $870
E) $880
Answer:
A) $840
Step-by-step explanation:
15•40 gives us how much money he makes a week normally
divide the result, 600, by 5 to find out how much he makes a day normally which is $120
now that we know how much he normally makes a day we can double $120 to $240 to show how much he makes on holiday days
so he makes $120 normally and $240 on holiday
120•3= 360
240•2= 480
then add
360+ 480= $840

Find the total package price from each store and then calculate how much you"lol save if you purchase the less expensive package
Complete Question:
You're planning to buy a new computer, monitor, and printer for your office. You've received the following prices from two stores:
Store 1 Store 2
Computer: 2,500 Computer: 2,350
Monitor: 595 Monitor: 435
Printer: 398 Printer: 349
Find the total package price from each store and then calculate how much you'll save if you purchase the less expensive package.
Answer:
[tex]Total = 3493[/tex] --- Store 1
[tex]Total = 3134[/tex] --- Store 2
[tex]Saved = 359[/tex]
Step-by-step explanation:
From store 1, the total cost is:
[tex]Total = 2500 + 595 + 398[/tex]
[tex]Total = 3493[/tex]
For store 2, the total cost is
[tex]Total = 2350 + 435 + 349[/tex]
[tex]Total = 3134[/tex]
By comparison: It is cheaper to buy from store 2
Because [tex]3134 < 3493[/tex]
Amount saved is calculated by subtracting the cheaper cost from the expensive cost:
i.e.
[tex]Saved = 3493 - 3134[/tex]
[tex]Saved = 359[/tex]

A clothing store charges a 10% tax on each purchase. If a shopper’s total before tax is $63, how much is the tax? Explain how you got your answer
Answer:
To calculate the sales tax that is included in a company's receipts, divide the total amount received (for the items that are subject to sales tax) by "1 + the sales tax rate". In other words, if the sales tax rate is 6%, divide the sales taxable receipts by 1.06.
Suppose you have a 7-cm by 5-cm rectangle. You increase the length by 1 cm and decrease the width by 1 cm. You continue to do this. What happens to the perimeter of the rectangle? The area? Explain why this happens.
Answer:
Step-by-step explanation:
P of original = 14 + 10 = 24
P of original l + 1 and w - 1 = 16 + 8 = 24
P of original l + 2 and w - 2 = 18 + 6 = 24
The perimeter remains the same each time since Perimeter is to the 1st power and you are summing; by subtracting from one and adding the same amount to another measure there is no change in perimeter
A of original = 7 x 5 = 35
A of original l + 1 and w - 1 = 8 x 4 = 32
A of original l + 2 and w - 2 = 9 x 3 = 27
A of original l + 3 and w - 3 = 10 x 2 = 20
A of original l + 4 and w - 4 = 11 x 1 = 11
The area decreases by 3,5,7,9 units each time since Area is to the 2nd power since you are multiplying two measures, now if you take the 2nd differences of 3,5,7,9 you see that they are 2 units apart each time, so are is squared and the 2nd differences are constant
