Answer:
C
Step-by-step explanation:
the answer is C because the pattern adds a row and a column each time
The answer is 45 because 2.50 times 18=45
Let's first write down the equations which we will require to solve for this problem.
Equation No. 1 -
x km/h = y mph
Equation No. 2 -
8 km/h = 5 mph
First of all, we will make y the subject by calculating the km/h when mph = 1. We will accomplish this by dividing both sides by 5 as displayed below:
Equation No. 2 -
8 km/h = 5 mph
5 mph = 8 km/h
5 / 5 mph = 8 / 5 km/h
1 mph = 8 / 5 km/h
Through this, we have found out:
m = 8 / 5
We will use the y = mx formula in order to obtain our final equation. We will substitute the value given in the second equation into the formula.
y = mx
y = ( 8 / 5 ) x
Answer:
28.5m
Step-by-step explanation:
Find the area of the top triangle first:
a=1/2bh
a=1/2(6)(2)
a=6 m
Next, the second triangle:
a=1/2bh
a=1/2(3)(3)
a=4.5 m
now the rectangle:
a=3(6)
a=18
add your answers: 18+4.5+6 =28.5m
