Answer:
1. 50 m
2. 80 cm
Step-by-step explanation:
1. There are 2 triangles, subtract the area of 1 of them from the other.
The triangle that needs to be subtracted: b = 20 m, h = 10 m
A = 1/2b * h = 1/2(20) * 10 = 10*10 = 100 m
The big triangle, the one that needs to be subtracted plus the one you need to find the area of: b = 20 cm, h = 15 cm, 1/2(20) * 15 = 10 * 15 = 150
150 - 100 = 50 c
2. Divide it into 3 parts:
1- 3*4 = 12
2. 7*(4 + 4) = 7*8 = 56
3. [(4 + 4) * (13 - 7 - 3)]/2 = (8*3)/2 = 24/2 = 12
12 + 56 + 12 = 80 cm
Answer:
12 divided by 2 + 4 - 2 x 3 is 4
Step-by-step explanation:
I did 12 divided by 2 first which was 6 then added 4 subtracted it by 2 then multiplied it by 3 and got 4.
Answer: 7
Step-by-step explanation:
Given : The recommended daily allowance for vitamin c is 60 mg per day .
Then, for one whole week , the recommended allowance for vitamin c will be :-
Also, there are 70 mg of vitamin C per 100 g orange.
1 g = 1000 ml
The proportion of Vitamin C in 100 g = 
1 oz =28.3495 grams
Then, 
Then, amount of vitamin C in 85048.5 mg = 
Then, the number of oranges have to eat each week to meet this requirement= 
Hence, about 7 oranges you would have to eat each week to meet this requirement.
