Answer:
4
Step-by-step explanation:
Answer:
Er you just multiply by 9.
Step-by-step explanation:
1*9 = 9
3*9=27
1*9=9
27*9=243
Answer: 84 degrees
Step-by-step explanation: I'm not quite sure how to explain this problem, sadly, but you basically add up the degrees together in the big triangle all together, and then figure out the rest.
We can rewrite this problem as:
What is 60% of 35?
"Percent" or "%" means "out of 100" or "per 100", Therefore 60% can be written as
60
100
.
When dealing with percents the word "of" means "times" or "to multiply".
Finally, lets call the number of members we are looking for "m".
Putting this altogether we can write this equation and solve for
m
while keeping the equation balanced:
m
=
60
100
×
35
m
=
2100
100
m
=
21
21
members must be present to have a vote.
The kilogram of grass eaten by the cow is 7kg and the kilogram of grass eaten by the horse is 6kg.
<h3>The two simultaneous equations that can be derived from the question:</h3>
9h + 45c = 369 equation 1
4h = 3c + 3
4h - 3c = 3 equation 2
Where:
c = kg eaten by cows
h = kg eaten by horses
<h3>What is the value of h?</h3>
In order to determine the value of h, multiply equation 2 by 15
60h - 45c = 45 equation 3
Subtract equation 3 from equation 1
69h = 414
h = 6kg
<h3>
What is the value of c?</h3>
Substitute for c in equation 2
4(6) - 3c = 3
24 - 3c = 3
21 = 3c
c = 7
