Answer:
[-5,5]
Step-by-step explanation:
1 1/4 * 2 + 2 1/2 * 1.5
change the fractions to decimals
1.25 * 2 + 2.5 * 1.5
2.5+3.75
6.25
The total cost is 6.25
No the points have to be on a cross on the x and y axis
The <em><u>correct answers</u></em> are:
3/2 - expansion; 1/4 - contraction; 4 - expansion; 0.8 - contraction; -3 - expansion.
Explanation:
A scale factor larger than 1 would be an expansion. The factors we have listed that are larger than 1 are 3/2 and 4.
A scale factor between 0 and 1 would be a contraction. The factors we have listed that are between 0 and 1 are 0.8 and 1/4.
A negative scale factor will result in a larger, inverted figure. This means the scale factor of -3 will be an expansion.
1 hour = 3600 seconds
Calculate feet per hour first:
3600 seconds / 3 = 1200
1200 x 20 feet = 24,000 feet in 1 hour
1 mile = 5280 feet
Calculate miles per hour:
24,000 / 5280 = 4.54 miles per hour.
Round the answer as needed.
