Answer:
A) 3
Step-by-step explanation:
If you simply look at the given numbers, it should be pretty clear that 3 tenths is 3 times 1 tenth.
When Mary puts 1/10 kg in each cage, she can do that for 3 cages with 3/10 kg of bird seed.
__
If you let c represent the number of cages, then the amount of bird seed used will be (1/10)c. This will be equal to the amount available when we use it all for filling cages:
(1/10)c = (3/10)
Multiply both sides of the equation by 10:
c = 3
Mary can fill 3 cages with available seed.
Step-by-step explanation:
4/m=16
4/m=16/1
16m=4
divide both sides by 16
therefore, m is equal to 0.25
Answer:
18
Step-by-step explanation:
We will try to find the angle on the left side of the small triangle. So we have to use Tan.
SOHCAHTOA
TanФ = 12/8
= 12/8 = 56.31°
So the other one is 33.69° It's the top left one of the smaller triangle.
The top right side of the bigger triangle is 56.31 because they both add up to make 90°
Now that we have an angle of the bigger triangle we will find the x.
Tan 56.31 = x/12
x = 18
Theres probably a easier way but i dunno
