Answer:
C = 131.88 cm
Step-by-step explanation:
the circumference (C) of a circle is calculated as
C = 2πr ( r is the radius ) , then
C = 2 × 3.14 × 21 = 131.88 cm
Answer:
Step-by-step explanation:
i = prt/100
i = $300×2×9 all divided by 100
i = 5400/100
i = $54
The average in January is -36°
The average in July is 17° warmer
So add 17 to -36
The average in July is -19°C
Answer:
28
Step-by-step explanation:
(35/5) ÷ (-3/4)
= (35/5) x (-4/3)
= 7 x (-4/3)
= -(7 x 4) / 3
= -28 / 3
hence the numerator is 28
The answers are 25 and x^3 because
25x^4 divided by 25 is x^4, which means it's a factor.
25x^4 divide by x^3 is 25x, which means it's also a factor.
25 isn't divisible by 4, and there's no y in the number, which makes the first and third answer impossible
