Landon babysits and works part time at the water park over the summer. One week, he babysat for 3 hours and worked at the water park for 10 hours and made $109. The next week he babysat for 8 hours and worked at the water park for 12 hours and made $177. How much does Landon make per hour at each job?
Answers
Answer:
Babysitting =$8.7
Water park =$8.7
Step-by-step explanation:
In 1 week
Babysitting =3 hrs
Water park = 10 hrs
Total =$ 109
In week 2
Babysitting = 8 hrs
Water park = 12 hrs
Total= $ 177
Both weeks
Babysitting =11 hrs
Water park =22 hrs
Total=$286
33 hrs = $ 286
11 hrs =?
11×286÷33=$95.3
33 hrs = $286
22 hrs = ?
22×286÷33=190.7
Babysitting she got $95.3 in both weeks
Water park she got $190.7(rounded offf)in both weeks
11 hrs = $95.3
1 hr = ?
1×95.3÷11=8.7 (rounded off )
22 hrs = $ 190.7
1 hr = ?
1×190.7÷22= 8.7( rounded off)

A large pizza is $18 and a small pizza is $12. Each topping is.50.
How my would it cost for a large pizza with 5 toppings> *
Answers
Answer:
$20.50
Step-by-step explanation:
The pizza itself is $18. If you wanted 5 toppings you would do .50 multiplied by 5. That would give you a total of $2.50 for the 5 toppings. 18 plus 2.50 is 20.50.
Answer:
A large pizza with 5 toppings will be $20.50
A small pizza with 5 toppings will be $14.50
5 toppings would cost $2.50
Step-by-step explanation:
.50x5=2.50
18.00x2.50=20.50
12.00+2.50=14.50

9. If LK MK, LK = 7x - 10, KN = x + 3, MN = 9x - 1), and KJ = 28, find L.
Answers
Answer:LJ = 18 + 28 = 46
Step-by-step explanation:
Suppose J, K, L, M, N are points on the same line.
MK = MN + (-KN) = MN - KN = 9x - 11 - x - 3 = 8x - 14
Since LK = MK and LK = 7x - 10, then
7x - 10 = 8x - 14
8x - 7x = -10 + 14
x = 4
LJ = MK + KJ
MK = LK = 7x - 10 = 7(4) - 10 = 28 - 10 = 18
LJ = 18 + 28 = 46
(01.02 MC)Which statement best explains the value of 18 − (−5)? The additive inverse of −5 is +5, so 18 − (−5) = 23. The additive inverse of −5 is −5, so 18 − (−5) = 23. The additive inverse of −5 is −5, so 18 − (−5) = 13. The additive inverse of −5 is +5, so 18 − (−5) = 13.
Answers
Hey there! I'm happy to help!
The additive inverse of a number is one that has its sign switched. If you put a - before a number, the sign switches. We put a - before -5, so its sign switches. -5's additive inverse is 5, so this 18+5, giving us 23.
The additive inverse of -5 is +5, so 18 - (-5)=23.

Step-by-step explanation:
When taking 100 samples of size 30 or greater from a population, exactly 95 of them will create a confidence interval that contains the true population mean. True or false?
This statement is false, or better still, ambiguous. 100 samples of size 30 (or greater) each, means 300 total and it can't be just 95 of them that will contain the true population mean.
2a + 4c = 38.00 solve for c
Answers
Answer:
c = 19/2 - 1/2a
Step-by-step explanation:
Step 1: Write equation
2a + 4c = 38.00
Step 2: Solve for c
Subtract 2a on both sides: 4c = 38 - 2a
Divide both sides by 4: c = 19/2 - 1/2a
Step-by-step explanation:
2 (a+2c)=38
a+2c=19

Answer:
2 y^6
Step-by-step explanation:
Simplify the following:
(2 x y^2)^5/((4 x^2 y)^2 x y^2)
Hint: | Distribute exponents over products in (4 x^2 y)^2.
Multiply each exponent in 4 x^2 y by 2:
(2 x y^2)^5/(4^2 x^(2×2) y^2 x y^2)
Hint: | Multiply 2 and 2 together.
2×2 = 4:
(2 x y^2)^5/(4^2 x^4 y^2 x y^2)
Hint: | Evaluate 4^2.
4^2 = 16:
(2 x y^2)^5/(16 x^4 y^2 x y^2)
Hint: | Distribute exponents over products in (2 x y^2)^5.
Multiply each exponent in 2 x y^2 by 5:
(2^5 x^5 y^(5×2))/(16 x^4 y^2 x y^2)
Hint: | Multiply 5 and 2 together.
5×2 = 10:
(2^5 x^5 y^10)/(16 x^4 y^2 x y^2)
Hint: | Compute 2^5 by repeated squaring. For example a^7 = a a^6 = a (a^3)^2 = a (a a^2)^2.
2^5 = 2×2^4 = 2 (2^2)^2:
(2 (2^2)^2 x^5 y^10)/(16 x^4 y^2 x y^2)
Hint: | Evaluate 2^2.
2^2 = 4:
(2×4^2 x^5 y^10)/(16 x^4 y^2 x y^2)
Hint: | Evaluate 4^2.
4^2 = 16:
(2×16 x^5 y^10)/(16 x^4 y^2 x y^2)
Hint: | Multiply 2 and 16 together.
2×16 = 32:
(32 x^5 y^10)/(16 x^4 y^2 x y^2)
Hint: | In (32 x^5 y^10)/(16 x^4 y^2 x y^2), divide 32 in the numerator by 16 in the denominator.
32/16 = (16×2)/16 = 2:
(2 x^5 y^10)/(x^4 y^2 x y^2)
Hint: | For all exponents, a^n a^m = a^(n + m). Apply this to (2 x^5 y^10)/(x^4 y^2 x y^2).
Combine powers. (2 x^5 y^10)/(x^4 y^2 x y^2) = 2 x^(5 - 1 - 4) y^(10 - 2 - 2):
2 x^(5 - 1 - 4) y^(10 - 2 - 2)
Hint: | Evaluate 5 - 1 - 4.
5 - 1 - 4 = 0:
2 x^0 y^(10 - 2 - 2)
Hint: | Evaluate 10 - 2 - 2.
10 - 2 - 2 = 6:
2 x^0 y^6
Hint: | Any nonzero expression to the zero power is one.
x^0 = 1:
2×1 y^6
Hint: | Simplify the expression.
Write 2×1 y^6 as 2 y^6:
Answer: 2 y^6

[tex]9.0(0)\\\\90.0(1)\\\\900.0(2)\\\\9000.0(3)[/tex]
