Answer: 27.7 square inches.
Step-by-step explanation:
Let 'a' be the side of equilateral triangle.
Then the perimeter of the triangle = a+a+a=3a
Given: Perimeter of the equilateral triangle = 24 inches We know that the area of a equilateral triangle is given by :-
What can be proven true in the diagram is the statement in letter C. angle CGB is complementary to angle AGD. It is because they both had the same vertex which is point G. Complementary angles are angles which are equal to 90 degrees wherein when you add both angles which are obviously 45 degrees, the sum is 90 degrees.
To find out the amount Jenna earns, you need to multiply how much she earns per hour by the amount of hours she works for.
If she earns $8.75 for 1 hour, and works for 20 1/5 hours, she'll earn:
8.75 x 20 1/5 = 176.75
Jenna earns $176.75 before tax.
x = 5i x =-5i
Step-by-step explanation:
x^2+25=0
Rewriting
x^2 - (-25)=0
Writing as the difference of squares
a^2 - b^2= (a-b) (a+b)
where a = x and b = (sqrt(-25)) =±5i
( x-5i) ( x+5i) =0
Using the zero product property
x-5i =0 x+5i =0
x = 5i x =-5i
Answer:
running 1.5 hours
Walking 4.5 hours
Step-by-step explanation:
Let the amount of time she spends on walking be x
d/3 + d/9 = 6 Multiply by 9
3d + d = 6*9
4d = 54 Divide by 4
4d/4 = 54/4
d = 13 2/4 = 13 1/2 = 13.5 miles
d/3 = 13.5/3 = 4.5 hours
d/9 = 13.5/<u>9 = 1.5 hours</u>
Total 6 hours
I hope this is the right interpretation.
