Answer:
Area of the rectangular doormat = 2/5 m²
Step-by-step explanation:
Length of the rectangular doormat = 4/5m
Width of the rectangular doormat = 1/2m
What is the area of the doormat?
Area of a rectangle = length × width
= 4/5m × 1/2m
= (4×1) / (5×2)
= 4 / 10
= 2/5 m²
Area of the rectangular doormat = 2/5 m²
Answer:
15years
Step-by-step explanation:
6000×10×t÷100=9000
600t=9000
t=9000÷600
t=15years
Logan, the way you have phrased this question makes it a bit hard to follow. I'm going to take the liberty of paraphasing it:
"Catalan drives an average of 1.4 times faster during the first 105 miles of her trip than she does during the second 105 miles."
As we are told, let X represent her speed during the first 105 miles of her trip. She drives more slowly during the second 105 miles. Thus, her speed during the 2nd 105 miles is X/1.4.
Remember: distance = (rate)(time), or time = (distance)(rate)
We need to determine an expression for the time she spends driving. Let T1 be the time required to drive 105 miles at speed X mph and T2 be the time required to drive 105 miles at speed (X/1.4) mph.
What is the total time required to drive these 210 miles?
Total time = (time required to drive 105 miles at X mph) + (time required to drive 105 miles at X/1.4 mph).
This gives you TIME SPENT DRIVING as a function of X, her speed during the first 105 miles of driving.
Answer:
A=bh=24*8=192
V=2(wl+hl+hw)=2·(4·3+15·3+15·4)=234
A=1311(big rectangle ---> (31-12)69)+2(12 x 23 ---> because of the two smaller rectangles=1311+552=1863
