Answer:
PB = 1.8
Step-by-step explanation:
PQ = 8 cm, BC = 10 cm and AB = 9 cm
∆ABC is similar to ∆APQ.
Therefore:

Plug in the values

Cross multiply
AP × 10 = 8 × 9
AP × 10 = 72
Divide both sides by 10
AP = 7.2
PB = AB - AP
PB = 9 - 7.2
PB = 1.8
Answer:
<h2> 2.11¢</h2>
Step-by-step explanation:
We are expected to solve the weighted average price per kilowatt hour.
Step one:
The formula is
W =∑wX/∑w
W=weighted average
w=weights applied to x values
X=data values to be averaged
Step two:
given the total killowatt hour is 1800
the 1st = 500 at 3¢
2nd= 1000 at 2¢
3rd = (1800-1000+500) at 1¢ =(1800-1500) at 1¢ = (300) at 1¢
Step two:
Substituting into the expression we have
W =(500*3)+(1000*2)+(300*1)/500+1000+300
W=1500+2000+300/1800
W=3800/1800
W=2.11¢
The average price per kilowatt hour the utility paid to Mr. Vestas last month is 2.11¢
Answer:
y=50x
Step-by-step explanation:
distance = 50 times the laps
100= 50 x 2
200 = 50 x 4
250= 50 x 5
400 = 50 x 8
Answer:
6.8
Step-by-step explanation:
Answer:
200×20 = 4000 And 15×30 = 450
