The slope is how much something increases or decreases by at a constant rate, for example if johnny buys 3 oranges every time he goes to the store the slope would be 3. the y-intercept is how many things you start with so if johnny already had 5 oranges before he went to the store the y-intercept would be 5. the equation for that situation would by y=3x+5... 3x is the 3 oranges johnny buys each time he goes to the store (the slope) and 5 is how many oranges he started with before going to the store at all (y-intercept)

maxonik [38]

Answer:

11\ gallons

Step-by-step explanation:

we know that

Haley's car gets at least 18 miles per gallon

so

by proportion

Find the minimum number of gallons she'll need for a trip that is 200 miles

\frac{1}{18}\frac{gallon}{miles} =\frac{x}{200}\frac{gallon}{miles}\\ \\x=200/18\\ \\x= 11.11\ gallons

Question 1.
tangare [24]

Answer:

1. 8.03 x 108 2. 6.8 × 10-9 3. 135,900 4. 2.5x10^-11

Step-by-step explanation:

Step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 803,000,000New Number: 8.03000000Step 2

Now, to find b, count how many places to the right of the decimal.

New Number:8.03000000Decimal Count:12345678

There are 8 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 8.03 (Please notice any zeroes on the end have been removed)

b = 8

Now the whole thing:

8.03 x 108

Step 4

Check your work:

108 = 100,000,000 x 8.03 = 803,000,000
