To find scale we have to provide common unit, so inches.
10 foot = 120 inch becauyse 1 foot = 12 inch so
10foot*12=120 ich
Now
8 inch in drawing is 120 in real, so the scale is 8:120
The name for facts in subtraction problems: Fact Family is a group of math facts that uses the same numbers, for addition, and subtraction.
Answer: =====> I believe is, Subtraction Fact Strategies, or Fact Families.
1. ). Strategy: ===> Think Addition:
1.). Subtraction Description ====> Using the known addition fact to solve the subtraction problem. Ex. 13-5, think what goes with 5 to make 13?
2.). Strategy: ===> Fact Families
2.). Subtraction Description ====> Think of the fact family to recall the missing number.
3.). Strategy ===> Build Up Through
3.). Subtraction Description ===> Ten
Used when either the subtrahend or minuend is 8 or 9. Ex: 14-9: start with 9 and work up through 10: 9 and 1 is 10 and 4 more makes 5.
4.). Strategy ==> Back Down Through Ten
4.). Subtraction Description: ==> Working backward with 10 as a “bridge”. Ex. 15-6, Take 5 away from 15 to get to ten. Then take one more away, leaving 9.
Hope that helps!!! : )
Answer:
(a) -2.3°/min
(b) -2.9°/min
Step-by-step explanation:
The average rate of change is the ratio of the difference in R values to the difference in the corresponding t values.
(a) m = (157.6 -226.6)/(30 -0) = -69/30 = -2.3 . . . degrees per minute
__
(b) m = (61.6 -119.6)/(70 -50) = -58/20 = -2.9 . . . degrees per minute
