Answer:
10 units
Step-by-step explanation:
Given that:
Cos a = 3 /5
From trigonometry ;
Cos θ = Adjacent / hypotenus
Side Adjacent angle a = 3 = FD
Hypotenus = 5 = DE
3 / 5 = FD / DE
FD = 6 units
3/5 = 6/DE
DE * 3/5 = 6
DE = 6 ÷ 3/5
DE = 6 * 5 /3
DE = 30 /3
DE = 10 units
Answer:
$620
Step-by-step explanation:
Let the price of refridgerator be "r"
price of washer be "w"
and
price of dryer be "d"
Total 1800, that means, we can write:
r + w + d = 1800
Also, refrigerator cost 250 more than washer, so we can write:
r = w + 250
The dryer is HALF (0.5) of washer, so we can write:
d = 0.5w
Now, we replace equation1 with equation 2 & 3, so get an equation in "w" and solve for w:
r + w + d = 1800
w + 250 + w + 0.5w = 1800
2.5w + 250 = 1800
2.5w = 1800 - 250
2.5w = 1550
w = 1550/2.5
w = 620
Thus, the washer costed $620
Answer:
13000m
Step-by-step explanation:
Given data
Total distance travelled= 65,000
Number of days= 5 days
Hence the distance covered per day is
= 65,000/5
=13000m
Therefore the distance covered per day is 13000m
You would divide 8 by 9 to get .8 (the 8 repeats)
Rounded to the thousandths, because the 8 repeats.
Answer:
49
Step-by-step explanation:
If there's 60 beads in total and 11 are round and the rest aren't all you have to do is subtract 11 from 60.
Like This: 60-11=49
To check your answer you can add them to see if you get 60. Like this: 11+49=60
