Answer:
Step-by-step explanation:
To find B, C and D
we make use of Pythagoras theorem
since the line A= 8.5inch and looking at critically we can see the 3 inch meet it at the center (we divide 8.5 inch into 2 to give 4.25inch)
using Pythagoras theorem
hypothenus²= opposite²+adjacent²
4.25²= 3²+b²
18.0625 - 9 =b²
9.0625 = b²
b = √9.0625 = 3.0103986447≈3.01
for c
3² + 3.01² = C²
9 + 9.0601 = 18.0601 =C²
C = √18.0601 = 4.24971763768 ≈ 4.25
C is a portion of the longest side meaning it will need to be divided by 2 = 4.25/2 =2.125
to get D
2.125² = 1.5² + D²
4.25 = 2.25 +D²
4.25 -2.25 = D²
2 =D²
D= √2 = 1.41421356237 ≈1.41
For the pan one, you would colour all 4 of them (lightly) because she used all 4. For the cutting them up one, you did it right. For the next one, the first thing you need to do is colour 1 slice on the first triangle, on the 3rd on colour 2 slices, on the 2nd one colour two slices, and on the 4th one colour 4 slices. (Colour these ones hard.)
Answer:
K = 8.3 repeating or 8 1/3
Step-by-step explanation:
3k - 5 = 20
Add 5 to the '-5' and 20 so you'll now have 3k = 25 (You're isolating the variable )
3k/3 = k
25/3 = 8.3 repeating or 8 1/3
K = 8 1/3 or 8.3 repeating.
Answer: 2400
========================================================
Work Shown:
(80 push-ups)/(2 minutes) = (x push-ups)/(60 minutes)
80/2 = x/60
40 = x/60
40*60 = x
2400 = x
x = 2400
He can do 2400 pushups per hour, assuming he keeps at this same rate.
Answer:
$0.84 I think is the answer
