Answer:
a) 5:3
b) 25:12
c) 1:2
Step-by-step explanation:
a) 20:12 = 20/12 = 10/6 = 5/3 = 5:3
b) 25:12 -> cannot be simplified so -> 25:12 itself
c) 10:20 = 1/2 = 1:2
Answer:
-50
Step-by-step explanation:
Put 2 where x is and do the arithmetic.
f(2) = -2(5^2) = -2(25) = -50
Answer:
7^x = 8
Step-by-step explanation:
log7 (8) =x
We know that loga (b) =c can be written as a^c =b
log7(8) =x becomes 7^x = 8
5 7/32 = 167/32
5/32 + 5/32 (2 wall thicknesses of the pipe) =10/32
167/32 - 10/32 = 157/32
= 4 29/32
Answer:
m3 is 60 degrees
Step-by-step explanation:
Angles 1 & 3 are complementary angles. What that means is that the two angles equal 180 degrees. We already have 120 degrees with m1, so subtract that from 180 for 60 degrees.
