We know that each row would require 62 bricks, and considering that the wall will have multiple rows, we will be multiplying 62 by the number of rows. Since the wall has 10 rows, Nick has to use the 62 bricks 10 times (since 1 row requires 62 bricks, he would have to build that 1 row 10 times.)
If we think about the operation of multiplication, we can write “62 ten times” as 62 x 10 (or, when calculated, 620 bricks).
Answer:
a) 325.72
Step-by-step explanation:
A=4pir^2
A=4x3,14x7.2x7.2
a=651.44
1/2a=1/2x651.44
=325.72
2.25x15= blah blah blah, and boom there is your answer
For this case, the first thing we must know is the following definition:
d = v * t
Where,
d: distance
v: speed
t: time
Therefore, the total distance traveled in this case is:
(5.5) * (0.5) + (1.5) * p = 13.25
Rewriting:
2.75 + 1.5p = 13.25
Clearing the value of p we have:
p = (13.25-2.75) / (1.5)
p = 7
Answer:
an equation representing this situation is:
2.75 + 1.5p = 13.25
