Answer:
1/18 pound each
Step-by-step explanation:
Take the number of pounds and divide by 12 people
2/3 ÷12
Copy dot flip
2/3 * 1/12
Rewriting
2/12 * 1/3
1/6 * 1/3
1/18 pound each
6in×2=12inches and 2/5×2=0.8 so the answer would be 12.8
Answer:
The base is 10 meters
Step-by-step explanation:
The area of a right triangle is (b × h) ÷ 2 = a
Let's input the given values and find the value of b:
(b × 4) ÷ 2 = 20
4b ÷ 2 = 20
2b = 20
b = 10
Check:
(10 × 4) ÷ 2 = 20
40 ÷ 2 = 20
20 = 20
It works!
Answer: Andrew = 20
Jimmy = 25
Richard = 100
Step-by-step explanation:
Let the number of Andrew's comic books be y.
Jimmy has five more comic books than Andrew. This means Jimmy has: y+5
Richard has four times as many comic book as jimmy. This means Richard has: 4(y+5) = 4y + 20
Since there are 145 comic books together. This can be rewritten as:
y + (y+5) + (4y+20) = 145
6y+25 = 145
6y = 145 - 25
y = 120/6
y = 20
Andrew has 20 comic books
Jimmy has five more comic books than Andrew. Jimmy has: 20+5 = 25
Richard has: 4y + 20 = 4(20) + 20 = 100
2{(cos^210+isin^210)}^2
2(cos^210-sin^10+2i*cos10*sin10)
2(cos20+i*sin20)
cos^2Ф-sin^2Ф=cos2Ф and 2sinФcosФ=sin2Ф here Ф=10°
