1/4 is the same as 0.25, so you can do 25 × 2 = 50, and then move the decimal point two places to the left to get 0.5.
Therefore your final answer is 0.5
Factor each number:
14=2*7
35=5*7
7 is a common factor, and no other (except 1), so 7 is the greatest common factor (GCF) of 14 and 35.
Answer:
169 m
Step-by-step explanation:
See the image below.
Line AB represents the monument and line BC its shadow
Line DB represents the man and Line BE it shadow.
The Sun’s rays are parallel, so AC||DE.
Then ∆ABC ~ ∆DBE
AB:BC::DB:BE
x/65.8 = 1.8/0.7 Multiply both sides by 65.8
x = 65.6 × 1.8/0.7
x = 65.6 × 2.571
x = 169 m
The height of the Washington monument is 169 m.
4x = 8, so x = 2
5y + 4 = 4, so 5y = 0, so y = 0
(2,0)
Answer:
80.
Step-by-step explanation:
When multiplying if the tenth place is " 7" then we look " next door" which is the ones and 8 is great then 5 so we count to from 8 to see when the next number ending in 0 would be in this case its 80. ( if the number is 4 or less count backwards to a number ending with 0 which in that case would have been 70 ) but the answer is 80.
