Answer:
94.2 cm
62.8 inch
Step-by-step explanation:
The circumference of a circle is 2πr, where r is the radius.
The diamater is twice the radius, d=2r.
1) 2π·15 ≈ 94.2 cm
2) r = 10 inch. 2π·10 = 62.8 inch.
since keyra types 80 words in two minutes it means than he types 40 words in a minute then she types 40x3=120 words in three minutes
Answer:
1. 4.5x
2. 4.5x+12=48
3. x=8
Step-by-step explanation:
4.5(8)+12=48
36+12=48
48=48
Answer:
1. 10:8 = 5:4 (simplest form)
2. 860:400 = 43:20 (simplest form)
3. 4415:1200 = 883:240 (simplest form)
Answer:
(x + 8)^2.
Step-by-step explanation:
x^2 + 16x + 64
8 + 8 = 16 and 8^2 = 64 so the factors are
(x + 8)(x + 8) or (x + 8)^2
