Answer:
3.68
Step-by-step explanation:
If 3/5 of the weight is apples, then 2/5 of the weight is pears.
2/5 * 9.2 = 3.68
<u>Answer:</u>
<u>Step-by-step explanation:</u>
Distance traveled by a car between two cities = 1/6 distance
Time taken to travel between the two cities = 3/5 hours
Therefore, to find how much of the distance the car can travel in 1 hour, we need to divide the given distance by the given time to get:
(
) ÷ (
)
Change the later fraction to its reciprocal to solve:
× 
=
Therefore, in one hour, the car can travel 5/18 of the distance.
Answer: C
Hello,
Step-by-step explanation:
WZ=7-3=4
YW²=XW*WZ=3*4=12 ==> WY=2√3
In the right triangle YWZ, using the Pythagorean's theorem:
YZ²=WY²+WZ²=12+4²=28
YZ=2√7≅5.29150....
Answer C
Functions are basically another way of expressing a way to get y or x or anything (mostly used for graphs) You will see functions like <em>f(x)=</em> <em>23y-5 </em>(that was made up). Basically the number in the parenthesis in front of the f is what you're finding. So the equation after the equal sign is how to find whatever is being found. So in this case, finding x can be pretty easy. By the way, when graphing this you have x as the run and y as the rise. <em />
Answer:
6
Step-by-step explanation:
The total of all the angles must be 180, since there is a straight line. We already know the 40 degree angle and the 90 degree angle, meaning that the remaining angle must be equal to 180 - 90 - 40, which is 50 degrees. Therefore, 50 = 7k + 8. 7k = 50-8 = 42, and k = 6.
