Area of a sector = 
.
Where,
radius (r) = 8.7 cm
Plug in the values into the formula
Area of sector = 
Area of sector = 
Area of sector = 171.74 cm² (approximated)
Answer:
<em>X</em> = 27 13/30
Step-by-step explanation:
First you need to find the least common denominator of 5 and 6 to get 30 so it is 25 5/30 + 7 12/30 + <em>x</em> = 60. From there you add the two together to get 32 17/30 + <em>x</em> = 60. Subtract 32 17/30 from both sides of the equation to get the value of <em>x</em> which comes out to 27 13/30.
Answer:
x=10
Step-by-step explanation:
x/2 + 10 = 35 - 2x
x/2 + 2x = 35 - 10
5x/2 = 25
5x = 25.2
5x = 50
x = 50/5
x = 10
First, we have to find 20% of $40.00 To find it, multiply 0.20 x $40.00 and you get $8
Now, take away the 20% away from $40.00
$40.00 - $8.00 = $32.00
Next, find 5% of $32.00 We have to multiply 0.05 x $32.00 and you get $1.60
We had $32.00 after the 20% discount, so add $32.00 + 1.60
Lydia paid $33.60 for her shirt.
Answer:
Option C. 15^2 + 20^2 = 25^2
Step-by-step explanation:from the question, we obtained the following:
The sides = 25, 15, 20
Since it is a right angle triangle, 25 is the longest side. Therefore their relationship is:
15^2 + 20^2 = 25^2
