Answer:
x=−3
Step-by-step explanation:
Average speed = total distance divided by total time.
In the first part, the car covered 490 km in 7 hours, but I think you mistyped the second part (“then covers a speed of 90km”) and a critical piece is missing to find the total distance and time.
First you put 2.13 on top of a fraction and 36 on the bottom. Then you divide 36 by 2.13 and put the answer, 16.90, on top of another fraction and put a 1 on the bottom of that other fraction.
Answer: 11.4
Step-by-step explanation:
area of rect. = 24
area of circle (half circle+half circle = full circle) = pi*r^2 = pi*(2*2) = pi*4 = about 12.57
2 = radius since 4 = diameter
24-12.57 = 11.43
round = 11.4
Answer:
(6 , 7.25)
Step-by-step explanation:
Given in the question coordinates (-4,-9) and (21,31.625)
x1 = -4
y1 = -9
x2 = 21
y2 = 31.625
Ratio
a : b
2 : 3
Formula to use
x = x1 + 
(x2-x1)
y = y1 + (y2 -y1)
Plug values on the formula
x = -4 + 
x = 6
y = -9 + 
y = 7.25
Co-ordinates of the point which divide the line into 2:3 is
(6 , 7.25)
