if BAC and DAE are complementary then their sum is equal to 90 degrees
90 - 36 = 44 degrees
Answer:
<h2>170</h2><h2 />
Step-by-step explanation:
given:
Ann, Ben, and Cindy were eating strawberries.
The ratio of the numbers of berries they ate is 5:5:7.
If Cindy ate 30 strawberries less than Ann and Ben together,
find:
what is the total number of strawberries the three of them ate?
solution:
add the ratios 5 +5+7 = 17
since Cindy ate 30, less than Ann and Ben together so, the factor is
7x = 5x + 5x - 30
7x - 10x = -30
x = 30/3
x = 10
ann 5 x 10 = 50
ben 5 x 10 = 50
cindy 7 x 10 =<u> 70
</u>
total = 170
Answer:
Year - (1993 - 1995)
Step-by-step explanation:
Rate of change in the number of toys sold =
In the interval (1990 - 1993),
Rate of change in number of toys sold =
=
= 4000
In the interval (1993 - 1995),
Rate of change =
=
= 5000
In the interval (2000 - 1995),
Rate of change =
=
= 3000
In the interval (2006 - 2000),
Rate of change =
=
= 1000
Therefore, rate of change in the number of toys sold is greatest in the interval (1993 - 1995).
Answer:
x= - 41/6, y= -6/23
Step-by-step explanation:
2x - 3y= - 1 ...(1)
0.8x - 3.5y=1/5 ...(2)
(2)×10 : 8x - 35y= 2 ... (3)
(1)×4 : 4x-12y= - 4 ...(4)
(3)-(4): 8x-35y=2
8x-12y= -4
_________
- 23y= 6
y= - 6/23
Substitute y= - 6/23 into any equation
Exp : 2x - 3(-6/23) = - 1
2x+18/23 = - 1
2x = - 41/3
x= - 41/6
Answer:
7^8
Step-by-step explanation:
Find what each exponent equals
7^12 equals 13,841,287,201
7^4 equals 2,401
Divide the two numbers
It equals 5,764,801 which is equivalent to 7^8
