Answer:

29 is your answer. I hope this helps you! Let me know if I got something wrong or if you need more help :)

Step-by-step explanation:

First, apply distributive property to 3(2+8). 3×2 and 3×8.

15 + (6 + 24) - 4^2

Add 6 and 24.

15 + 30 - 4^2

Simplify 4^2. 4^2 is the same as 4×4. 4 times 4 is 16.

15 + 30 - 16

Add 15 and 30.

45-16

Subtract.

your recipe calls for 1/2 a pound of potatoes. You use 1/6 of the bag of potatoes. whats the number of pounds per bag
zhannawk [14.2K]
I you use 1/6 of the bag for 1/2 a pound then you need to set up a proportion.

1/6 bag / 1 bag = 1/2 pound / x pounds      Cross Multiply
(1/6)*x = 1/2 pounds * 1 bag Divide by 1/6

Remember: in a 4 level fraction, the denominator inverts and multiplies.


x = {x = }\frac{ \frac{1}{2} }{ \frac{1}{6} } \\ \\ {x =} \frac{1}{2} *  \frac{6}{1} \\ \\{x = }  \frac{6}{2} = 3

Svetllana [295]

Answer:

Step-by-step explanation:

1) Price of 8 pack of toothbrushes = $ 18.12

Price he paid after using coupon  = 18.12 - 3  = $ 15.12

Unit rate = Price he paid ÷ number of toothbrushes

              = 15.12 ÷ 8

              = $ 1.89

2) 0.5 hours = 30 minutes

Duration of guitar class on Monday = 30 minutes

Duration of guitar class on Tuesday = 1.5 hours = 1 hr 30 min

Duration of guitar class on Thursday = 2 hrs

Total duration  = 30 min + 1hr 30 min + 2 hrs

                         = 4 hrs

Amount paid for 4 hrs = $ 180

Rate per hour = 180 ÷ 4

                       = $ 45

ryan deposits $775 in an account that pays 1.24% simple interest for four years. Brian deposits $775 in an account thats 1.24% s
AleksAgata [21]

Answer:

Principal (p) = $775

Rate of interest (r) = 4.24% = 0.0424

No of years/time (t) = 4 years

Simple interest = ptr

= 775 × 4 × 0.0424

= 131.44 dollars

Hence simple interest after 4 years is $131.44

Amount = simple interest + principal

= 775 + 131.44

= 906.44 dollars

Hence amount after 4 years is $906.44

RESULT

906.44 dollars
