1)
8.75 * 20 = 175
8 * 20 = 160
175 - 160 = 15
He'd make $15 more working at the amusement park.
2)
Semi-monthly means twice a month. So, her company is going from 2 to 4 pay periods.
3280 * 2 = 6560 (is what she makes per month)
6560/4 (because 4 weeks in a month) = 1640
OR (An alternative method.)
3280/2 = 1640
She'll be paid $1640 per week.
4)
105,000/12 (12 months in 1 year) = 8750 (He makes this per month)
8750 * 2 = 17500
He makes 17500 semi monthly
8750 /4 = 2187.5
2187.5 * 2 (because bi-weekly) = 4375
He makes 4375 bi-weekly
8750/4 = 2187.5
He makes 2187.5 every week
Dont forget to add the dollar signs. I didnt add them, but you need to. If you need me to add them I can.
Answer:
Step-by-step explanation:
(5^3/2)^-2/3 = 0.2 ⇒ E
(256^0.5)^1.25 = 32 ⇒ C
(81^1/6)^3/2 = 3 ⇒ F
(1024^0.03)^20 = 64 ⇒ D
(1000^4/7)^7/3 = 10,000 ⇒ B
(49^5/2)^0.2 = 7 ⇒ A
Step-by-step explanation:
* Lets explain how to solve the problem
- If we have base x to a power n and all to the power of m then we
multiply the two powers to be one power on the base
- [(x^n)^m] = x^(nm)
* Lets solve the problem
∵
∴ (5^3/2)^-2/3 = 0.2 ⇒ E
∵
∵ 256 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 = 2^8
∴
∴ (256^0.5)^1.25 = 32 ⇒ C
∵
∵ 81 = 3 × 3 × 3 × 3 = 3^4
∴
∴ (81^1/6)^3/2 = 3 ⇒ F (answer F must be 3 not 0.333)
∵
∵ 1024 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 = 2^10
∴
∴ (1024^0.03)^20 = 64 ⇒ D
∵
∵ 1000 = 10 × 10 × 10 = 10³
∴
∴ (1000^4/7)^7/3 = 10,000 ⇒ B
∵
∴ (49^5/2)^0.2 = 7 ⇒ A
