Answer:
7.5
Step-by-step explanation:
It is longer than 5, so cross 2.5 and 5 out, 10 is too big, so 7.5 is the correct answer
Perpendicular lines have slopes that are negative reciprocals
so if m1 = -3
the perpendicular line has a slope of 1/3
Answer:
Step-by-step explanation:
<u>Given:</u>
Speed = v = 54 km/h
Time = 1 hour 20 min = 1 hour (20/60) hour = 1.33 hrs
<u>Required:</u>
Distance = S = ?
<u>Formula:</u>
S = vt
<u>Solution:</u>
S = (54)(1.33)
S = 71.82 km

Answer:
Step-by-step explanation:
3C + 8T = 58 ----- (eq1)
5C + 2T = 23 ------(eq2)
Multiply equation (1) by 5 and equation (2) by 3
15C + 40T = 290 -----(eq3)
15C + 6T = 69 ----------(eq4)
Subtract equation (4) from (3)
34T = 221
T = 221/34
T = $6.5
Therefore 1 Table will cost $6 and 5 cents
Solve for (C) in equation (1)
3C + 8T = 58
3C + 8(6.5) = 58
3C + 52 = 58
3C = 58-52
3C = 6
C = 6/3
C = $2
1 Chair will cost $2
Answer:
5% decrease
Step-by-step explanation:
A percentage change can be calculated using the formula ...
percentage change = ((new value)/(old value) -1) × 100%
Using the given population values, we can find the change to be ...
percent change = (23221/24528 -1) × 100% = (0.947 -1) × 100%
= -5.3% . . . . . a negative change indicates a decrease
The percentage decrease in the town's population is 5%.
