In this graph, we see Chelsea types 50 words per minutes.
To find the answer, I will use tree diagram:
50 words in 1 minute
175 words in ?minutes
Step 1:
Cross multiply
175×1=175
Step 2:
Use division
175÷50=3.5 or 3 1/2 minutes. As a result, Chelsea types 175 words in 3.5 minutes or 3 1/2 minutes. Hope it help!
1) Use the pathagreom theorem; a^2+b^2=c^2
(The hypotenuse is always c. The other two legs can be either a or b.)
*use x for the unknown side*
1. Plug in the measurements
4^2+x^2=8.5^2
2. Solve
16+x^2=72.25
RADICAL(56.25)=> 7.5
The measure of the other side of the triangle (x) is= 7.5 m
2) Draw a square with the measure of 20 cm on each side.
Draw a diagonal line across the square.
(Use the pathagroeam theorem)
We know that the legs are 20, and 20. The hypotenuse is what we are trying to find (x).
1. Plug in the measurements
20^2+20^2=x^2
2. Solve
800= x^2
20 RADICAL(2)=> 28.28
The measure of the other side of the triangle (x) is= 28.3 cm
4 just count how many are there that are between 19-21
Answer:
x = 5.25
Step-by-step explanation:
(the answer above is if you are looking for the x value)
first, put the numbers with x values on one side and non x values on the opposite site.
then, solve for x.
