Area of a rectangle = Length * width.
Small rectangle A = 1m * 3m = 3 square meters
Big rectangle A = 5m * 6m = 30 square meters.
30 square meters + 3 square meters = 33 square meters
Daniel needs 33 square meters of carpet tiles
The fraction of the cake that was ron's pieces is 1/5.
<h3>What is the fraction of the cake was ron's pieces?</h3>
Ratio demonstrates how many times one number can fit into another number. Ratios contrast two numbers by ordinarily dividing them. A/B will be the formula if one is comparing one data point (A) to another data point (B).
Since Mrs Jones gave 1/5 of a cake to her neighbour, the remaining fraction will be:
= 1 - 1/5
= 4/5
The fraction of the cake that was ron's pieces will be:
= 2/(1+3+4) × 4/5
= 2/8 × 4/5
= 8/40
= 1/5

Represent
r=number of rabbits
c=number of chickens
1 rabbit=4 feet and 1 head
1 chicen=2 feet and 1 head
rabbits head+chicen heads=72
1r+1c=72
feet=200
4 times r+2 times c=200
4r+2c=200
divide both sides by 2
2r+c=100
we have
r+c=72
2r+c=100
make first equation negative and add to second equation
-r-c=-72
<u>2r+c=100 +
</u>1r+0c=28
r=28
subsitute
r+c=72
28+c=72
subtract 28
c=44

Answer:
∠b = 53°
Step-by-step explanation:
Complementary angles sum to 90°, thus
a + b = 90, that is
37 + b = 90 ( subtract 37 from both sides )
∠b = 53°
