Answers
Answer:
Step-by-step explanation:
area of blue triangle = 0.5×8×3 = 12 cm²
area of A = 5×12 = 60 cm²
area of C = area of A
area of B = 8×12 = 96 cm²

Answer:
240cm²
Step-by-step explanation:
The paved area is a square with sides 2 m long.
The paving stones for this area are squares that measure 50 cm by 50 cm
How many paving stones are needed?
Answers
Answer:
Step-by-step explanation:
2 meters = 200 cm
200 cm × (1 block)/(50 cm) = 4 blocks
4 blocks by 4 blocks = 16 blocks
Answer:
16 paving stones
Step-by-step explanation:
1 m = 100 cm
The square has sides 200 cm long
Its area is 200(200) = 40000 sq cm
Each paving stone has an area of 50(50) = 2500 sq cm
So 40000/2500 = 16 paving stones

Sixteen is divided by the sum of the number q and 1. The result is four. What is the number.
Answers
Answer:
The number is 3.
Step-by-step explanation:
Ok, so here we're solving for a variable. The equation would be:
16 ÷ (q + 1) = 4
We can rewrite this as:
4(q + 1) = 16
First, you need to isolate q + 1. To do that, you to the inverse of the operation. IN this case, division is the inverse of multiplication. So:
4(q + 1) = 16
÷4 ÷4
q + 1 = 4
Alright, now we isolate q. The inverse of addition is subtraction, so we do this:
q + 1 = 4
- 1 - 1
q = 3
Now for our check:
16 ÷ (q + 1) = 4
16 ÷ (3 + 1) = 4
16 ÷ 4 = 4
4 = 4
q = 3

B or every 3 minutes there is 11 put up
Step-by-step explanation:
So 22 and 6 we divide them by 2 we get 11 and 3
3.7 x 2 is 22.2 so it’s just a bit over out 22
0.27 x 6 is 1.62 which is not 22
so my conclusion it’s 11 shingles put up each minute

Before you read this!! To me, it looks like 8 is the entire length of lineJL, but it may only be the length of lineJM. I've written the steps for lineJL=8 NOT lineJM=8. If this is not the case and 8 is only the length of lineJM let me know so I can fix my answer!
Step-by-step explanation:
The area of a triangle is A=1/2(b)(h)
B=base
H=height
Your height is found in the line in the middle of the triangle, for you it is 6.
The base is the long bottom line on the triangle (lineJL), for you it is 8.
So let's put it in.
A=1/2(8)(6)
A=24sq units (C)
