Answer:23
Step-by-step explanation:
Every hour at 12km/h I would go 12km. Simple.
The distance traveled in km is equal to 12 times how many hours you go.
If I go 27 km, I can go in reverse and divide by 12 to get 2.25 hours.
A quarter of an hour is 15 minutes, so the answer would be 2 hours and 15 minutes.
Answer:
Area = 960 cm^2
Step-by-step explanation:
Perimeter (P) = 2 (l + w)
P = 2l + 2w
Let the length be 5x
Let the width be 3x
From the question, P = 128.
Therefore:
128 = 2l + 2w
Divide both sides by 2.
l + w = 64
Recall we said:
l = 5x
w = 3x
So then:
5x + 3x = 64
8x = 64
Divide both sides by 8
x = 64/8
x = 8.
Since x = 8
Length = 5x = 5*8 = 40cm
Width =3x = 3 * 8 = 24cm
Area of a RECTANGLE:
Area = length * width
Area = 40 * 24
Area = 960 cm^2
Step-by-step explanation:
The graph of rectangular hyperbola represents the function f(x)=4/x.
Do parentheses first according to PEMDAS.
3 squared is 9 and add 4 to get 13
Do 52 minus 13 to get 39
