• A car uses 30 gallons of gasoline for a trip of 800 miles. How many gallons would
nevsk [136]

Quantity of gasoline needed by a car to run 800 miles = 30 gallons

Quantity of gasoline needed by a car to run 1 mile =

= 30 ÷ 800

= 0.0375 gallons

So , to run 1 mile a car would need = 0.0375 gallons of oil

To run 700 miles the quantity of gasoline needed =

= 700 × 0.0375

= 26.25 gallons of gasoline

Therefore , a car will use 26.25 gallons of gasoline on a trip of 700 miles .

I need help with this math
Zinaida [17]

Answer:

D

Step-by-step explanation:

∠1 + ∠2  =  180   {Supplementary angles}

6x + 15 + 3x + 3 = 180

6x + 3x + 15 + 3 = 180      

Combine like terms

9x + 18 = 180

Subtract 18 from both sides

9x = 180 - 18

9x = 162

x = 162/9

x = 18

∠2 = 3x +3

     = 3*18 + 3

     = 54 + 3

∠2 = 57°

What is the slope of the line given (1,1) and (0,0)
yaroslaw [1]

The slope of the line passing the points (1, 1) and (0, 0) is 1

<h3>Slope of a line</h3>

The formula for calculating the slope of a line is expressed as

Slope = y2-y1/x2-x1

Given the coordinate points (1, 1) and (0, 0)

Substitute the given coordinate points

Slope = 0-1/0-1

Slope = -1/-1

Slope =1

Hence the slope of the line passing the points (1, 1) and (0, 0) is 1
