Line up corresponding parts of the similar triangle to make ratios.
You need 3 parts of the 6, including one complete fraction.
Next cross-multiply to solve for the missing sides.
# 15
a/x = b/y = c/z
6/10 = 8/y
cross-multiply
6y = 8*10
6y = 80
divide both sides by 6
y = 13 1/3 or 40/3
CHECK
6/10 ??=?? 8/ (13 1/3)
.6 = .6 CHECKS
# 16
4/7 = c/5
cross-multiply
7c = 4 * 5
7c = 20
divide both sides by 7
c = 20/7
CHECK
4/7 ??=?? (20/7)/5
.5714 = .5714 CHECKS
Answer:
<h2>96 ft²</h2>
Step-by-step explanation:
The formula of an area of a trapezoid:
- bases
- height
We have:
Substitute:
8.88 x 10^8
To find out the number used in the scientific notation, move the decimal point to where there is one number on the left, giving us 8.88. From then, count the amount of times the decimal moved, which is 8, and there's your scientific notation
Answer:
There are 2 different ways, depending on the amount of data given;
<em>1st way:</em> When only the line on the graph is given (Without any coordinate points given) then the slope could be found out with the formula of <u>Rise/Run, or Change in y / Change in x</u>
<em>2nd way: </em>When a line and 2 coordinate points are given, the the formula that would be used is:<u> </u>
<u>, where X₁ and Y₁ are the coordinate points of the 1st given point, and X₂ and Y₂ are the coordinate points of the 2nd given point.</u>
Hope this helps!
