Answer:
Answer:The formula for the area of a parallelogram is A = bh, and the formula for area of a triangle is A = 1/2bh. Since a triangle is half of the area of a parallelogram with the same base and height, the only difference in the formula is 1/2.
Step-by-step explanation:
A triangle with three equal sides is an equilateral triangle. A triangle with all acute angles is called an acute triangle. If a triangle fits both descriptions, it is an equilateral acute triangle. Hope this is what you were looking for!
When you are dividing fractions you need to flip the second fraction and change the sign to multiply. So for this question you'd get:
5/6 x 8/7
then you multiply as normal.
getting you the answer of 40/48
this is equivalent to 5/6

Answer:

Step-by-step explanation:
Arithmetic sequence:

Here a is the first term and d is the common difference.
⇒
------------(I)
⇒ a + 19d = 100 ---------(II)
Subtract equation (I) from (II)
(I1) a + 19d = 100
(II) a + 13d = 46
<u>- - -</u>
6d = 54
d = 54 ÷ 6

Substitute d = 9 in equation(I) and find 'a',
a + 13*9= 46
a + 117 = 46
a = 46 - 117
a = -71

= -71 + 18
= -53

= -71 + 54
= -17

= -71 + 9*n - 1 *9
= -71 + 9n - 9
= -71 - 9 + 9n
= - 80 + 9n
