Answer:
17.80"
Step-by-step explanation:
Weekly Rainfall total for September :
Week 1, 3.49″
Week 2, 1.73″
Week 3, 12.38″
Week 4, 0.21″
Rounding each week's total to the nearest tenth of an INCH before summing up:
WEEK 1 ; 3.50''
WEEK 2 ; 1.70"
WEEK 3 ; 12.40"
WEEK 4 ; 0.20"
TOTAL RAINFALL FOR SEPTEMBER :
(WEEK 1 + WEEK 2 + WEEK 3 + WEEK 4)
(3.50 + 1.70 + 12.40 + 0.20)
= 17.80"
Answer:
Step-by-step explanation:
If two triangles are similar, the ratio of the area of the triangles is proportional to the squares of its corresponding sides.
area of ΔJKL/area of ΔLMN = (JK)²/(NM)²
Cross multiply,
49*(NM)²= 1225
NM = 5 cm
Answer:
250 miles
Step-by-step explanation:
Let number of mile driven be x
plan 1: Cost = 0.7x
plan 2: Cost = 50 + 0.5x
for both plans to cost the same,
Plan 1 Cost = Plan 2 Cost
0.7x = 50 + 0.5x (solve for x)
0.7x - 0.5x = 50
0.2x = 50
x = 250 miles
