Solution:
<u>Note that:</u>
- Area of triangle = 6 3/8 yd²
- Height of triangle = 2 1/2
- Area of triangle = 1/2 x base x altitude
<u>Use the formula to find the base of the triangle.</u>
- 1/2 x base x altitude = 6 3/8 yd²
- => 1/2 x base x 2 1/2 = 6 3/8 yd²
- => 1/2 x base x 5/2 = 6 3/8 yd²
- => 5/4 x base = 6 3/8 yd²
- => base = 6 3/8 ÷ 5/4 yd
- => base = 51/8 x 4/5 yd
- => base = 51/2 x 1/5 yd
- => base = 51/10 yd
The length of the base is 51/10 yards.
They're all prisms. Hexagonal prism, cube, triangular prism, octagonal prism, and rectangular prism. Each have a quadrilateral for a base.
Answer:
$15.75
Step-by-step explanation:
five percent of 15 is 0.75. So you add that to 15 dollars and you get 15.75
Answer: 9 or 10
Step-by-step explanation:
That is an isloated triangle.
30+[ ]+[ ]= 180 degrees.
Reminder: [ ] & [ ] is a same amount of number.
So 11*x-18 is [ ].
180-30= [ ] & [ ].
[ ] & [ ]= 150.
Then, [ ] is 150/2.
[ ]= 75.
<u>(11*x - 18)= 75 degrees.</u>
9*9-18= Answer.
