we know that
In a right triangle
Applying the Pythagorean Theorem
where
a and b are the legs of the triangle
c is the hypotenuse of the triangle
Step N
<u>Assume that the third side is a leg</u>
In this case we have
Solve for b
substitute the values
Step N
<u>Assume that the third side is the hypotenuse</u>
In this case we have
substitute the values
Step N
<u>Find the difference of the third sides</u>
therefore
<u>the answer is</u>
Answer:
Multiply
Step-by-step explanation:
the cost of an item or service by the sales tax in order to find out the total cost. The equation looks like this: Item or service cost x sales tax (in decimal form) = total sales tax. Add the total sales tax to the Item or service cost to get your total cost.
Answer: 91 students ride the bus
For this problem, you can set up a proportion where:
w = those who walk to school
r = those who ride the bus to school
Then include the ratio (1:7) as a fraction (1/7) and the value that is known (13).
Cross multiply (create an "x").
4x-8 = 31
4x = 31 + 8
4x = 39
x = 9.75
