Answer:
Step-by-step explanation:
(fog)(x) = f(x)*g(x)
= 8x * (2x + 1)
= 8x * 2x + 8x * 1
= 16x² + 8x
Answer:
Money with Mary = $28
Money with Vivan = $12
Step-by-step explanation
Money with Mary = $ m
Money with Vivan = $v
If mary gave vivan $8 they would have same amount. $ 8 is reduced from Mary's amount 'm' and $8 is added to vivan amount 'v'
m - 8 = v + 8
m = v + 8 +8
m -v = 16 ----------------(I)
If vivan gives mary $8, then mary would have 9 times as much as vivan.
9(v - 8) = m + 8
9v - 72 = m + 8
9v - m = 8 + 72
-m + 9v = 80 --------------(II)
Add equation (I) and (II). Thus m will be cancelled and we will get the value of v
(I) m - v = 16
(II) <u>-m + 9v = 80</u> {Now add}
8v = 96
v = 96/8
v = $ 12
Plugin v = 12 in equation (I)
m - 12 = 16
m = 16 +12
m =$ 28
Suppose ABCD has sides a and b. The length of one of ABCD's diagonals is given by a2+ b2 = c2, where c is one of the diagonals.
Answer:
- 0.167 < 0.5 ≤ 1.167
means 1/2 is -0.167 less
and 1/2 is equal to 1.167 when 2/3 is set to distance each way.
Step-by-step explanation:
we can evaluate what 2/3 equals by equating the number to decimal
0.33 = 1/3 so 0.667 = 2/3
We then just subtract and add to 1/2
0.5 + 0.667 = 1..167
0.5 - 0.667 = -0.167
Answer:
70%
Step-by-step explanation:
=10.50/35.00%
=30%
