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

Step-by-step explanation:
n Over 54 EndFraction = StartFraction 4 Over 9 EndFraction
n/54 = 4/9
Cross product
n * 9 = 54 * 4
9n = 216
n = 216/9
n = 24

Find the hypotenuse of a right triangle that has a 13cm leg and a height of 7cm
Answer:
14.76 cm
Step-by-step explanation:
Use the pythagorean theorem:
a² + b² = c²
Plug in the side lengths and solve for c:
7² + 13² = c²
49 + 169 = c²
218 = c²
14.76 = c
So, the hypotenuse is approximately 14.76 cm

How many liter of 15% weed killer mixture must be added to 5 liters of 10% weedkiller mixture to make 12% weed killer mixture?
Answer: 3 1/3 liter
Brainliest? <3
let x equal the number of liters of 15% weedkiller.
your equation is .15 * x + .10 * 5 = .12 * (x + 5)
simplify to get .15 * x + .10 * 5 = .12 * x + .12 * 5
simplify further to get .15 * x + .5 = .12 * x + .6
subtract .12 * x from both sides and subtract .5 from both sides and simplify to get .03 * x = .1
divide both sides by .03 to get x = .1 / .03 = 3.333333333 rounded to 9 decimal digits.
you would need 3.333333333 liters of 15% solution to be added to 5 liters of 10% solution to get 8.333333333 liters of 12% solution.
.15 * 3.333333333 = .5
.10 * 5 = .5
.5 + .5 = 1
5 + 3.333333333 = 8.333333333
1 divided by 8.333333333 = .12 which is equal to 12%.

1⁵ + 5² / 25⁰ - 5¹=
Answer: 6.5
Step-by-step explanation:
1 (to the power of 5) is 1 and 5 (to the power of 2) is 25.
25 (to the power of 0) is 1 and 5 (to the power of 1) is 5.
1 + 25 = 26 and 1 - 5 = -4.
Since the slash means division in math and any number to the power of 0 is always 1.
The answer would be: -6.5.
The solution for the expression [tex]\frac{(1^5 + 5^2)}{(25^0 - 5^1)}[/tex] after simplifying is,
[tex]\frac{(1^5 + 5^2)}{(25^0 - 5^1)} = \frac{- 13}{2}[/tex]
We have to give that,
The expression to simplify is,
⇒ [tex]\frac{(1^5 + 5^2)}{(25^0 - 5^1)}[/tex]
Simplify the expression by simplifying each term in a given fraction,
⇒ [tex]\frac{(1^5 + 5^2)}{(25^0 - 5^1)}[/tex]
Since,
1⁵ = 1
5² = 5 × 5
= 25
25⁰ = 25
5¹ = 5
Substitute all the values,
⇒ [tex]\frac{(1 + 25)}{(1 - 5)}[/tex]
⇒ [tex]\frac{26}{-4}[/tex]
⇒ [tex]\frac{-26}{4}[/tex]
Simplify the fraction in simplest form,
⇒ [tex]\frac{- 13}{2}[/tex]
Hence, The solution is, - 13/2

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]
