Answer 1

Answer: 0.6 in 10 % ; 0.4 in 15 %

Step-by-step explanation:

1. (x*10%) + (y*15%)/ x+y=12%

2. x+y = 1 x= 1-y

(0.1x + 0.15y/ x+y= 12/100) * 100

(10x + 15y/x+y = 12)*(x+y)

10x+15y= 12x + 12y

-2x=-3y

2x = 3y 2(1 - y)= 3y

2-2y=3y 2= 5y

y= 0.4

x= 0.6

Gabriella made 5% of her free throws over the season. If she shot 180 free throws, how
many did she miss?

Answers

5% made means that out of every 100 shots she made 5 and therefore she missed 95 of them. You divide 95 by 100. To get percentage of missed shots in decimal form. It would be 0.95. Then multiply by the number of shots she took. Your answer would be 0.95 x 180

HELP PLEASE!!! Maia walks 12 miles. Then she walks 1/4 of that distance. select ALL of the expressions that represent the total distance she walks.

Answers

Answer:

1, 2, and 3

Step-by-step explanation:

The expressions that represent the total distance she walked are 12 + 0.5 × 12, 12(1 + 0.5), and 12×1.25.

What is a fraction?

A fraction is a part of the whole represented by a/b, where a and b are any integers.

Given that, Maia walks 12 miles and then 1/4 of 12 miles.

The total distance is:

12 + 1/4 of 12

= 12 + 1/4×12

= 12 + 0.5 × 12

=12(1 + 0.5)

= 12×1.25

= 15

Hence, the expressions that represent the total distance she walked are 12 + 0.5 × 12, 12(1 + 0.5), and 12×1.25.

g(1)= -2

g(2)= 6

g(n)=g(n−2)⋅g(n−1)

Find g(3). Show me the solutions and calculations.

Answers

Answer:

g(3) is -12

Step-by-step explanation:

Given that

g(1)= -2

g(2)= 6

g(n)=g(n−2)⋅g(n−1)

Now the g(3) is

g(3) = g(3 - 2) . g(3 - 1)

= g(1).g(2)

= (-2) (6)

= -12

Hence, g(3) is -12

Kami went out to eat. She ordered a sandwich and chips. The total was $12.50 including tax. How much will she pay with a 15% tip

Answers

Answer:

Step-by-step explanation:

Hello! So with finding out the total + tax, we just multiply $12.50 by .15 (that is our 15% tip). Then we add that new number to $12.50 and that is the total with the tip! Let's do it,

12.50 * .15 = 1.88

12.50 + 1.88 = $14.38
