Answer:

1) 29.16

2) 7/2

3) a = 8/25  

4) x = 4/15  

5) d = 23 1/3

Step-by-step explanation:

1) (45+3 3/5 )·0.6 = 48 3/5·0.6  = 29.16

2) (4÷ 4/7) ∙0.3 / (2.88÷4.8)   = (4 ∙7/4)∙0.3 / 0.6  = 7/2

3) 2 1/7 :(15a)= 5/14 :(0.8)

2 1/7 ∙0.8 = 5/14 ∙15a

1 5/7 = 5 5/14 a

1 5/7 : 5 5/14 = a

8/25 = a

4) 3x−1/5 = x+1/3

-1/5 - 1/3 = x - 3x

-8/15 = -2x

-8/15 : -2 = x

4/15 = x

5)(0.3d−1) / (3 1/3)=0.84: 7/15

(0.3d−1) =0.84: 7/15  ∙ 3 1/3

0.3d = 6 + 1

d = 7 :  0.3

d = 23 1/3

After joining two pieces of a picture frame together, a frame maker checks her work by measuring the diagonal (see the illustrat
tigry1 [53]
The diagonal (hypotenuse) is 13 in.

You need to use the Pythagorean Theorem

{a}^{2} + {b}^{2} = {c}^{2}
then just plug in the numbers and solve for c.

{12}^{2} + {5}^{2} = {c}^{2}
\sqrt{169} = c
13 = c

Please Help!!!!!!
jonny [76]

Answer:

Step-by-step explanation:

The distance that you travelled in your hummer between Olympia and Spokane is 319.4 miles.

You fill up your gas tank with 28.68 gallons of premium gasoline that costs $2.89 per gallon. This means that the total cost of premium gasoline that you bought would be

2.89 × 28.68 = $82.8852

your gas mileage in miles per gallon is 319.4/28.68 = 11.14 miles per gallon.

Therefore, if it costs $82.8852 to drive 319.4 miles,

then the cost of just one mile in your hummer would be

82.8852/319.4 = $0.26 per mile.
