Answer:

60° = m∠CED

30° = m∠AEB

Step-by-step explanation:

Since 90° is the m∠CEB, we already know the angle measures of the other two that got to be half and half of each other:

m∠AEB = ½m∠CED

$30 = \frac{1}{2}(60)$

This is like the 30°-60°-90° theorem. Always keep these in mind because you will never know when they will come in handy. The other one is called the 45°-45°-90° theorem, which in this case would not apply because two legs would have to congruent, which in this case they are not.

I am joyous to assist you anytime.

3 (Picture) CONVERGENT AND DIVERGENT SERIES PLEASE HELP!!

scoundrel [369]

Answer:

Option C

Step-by-step explanation:

The sum of finite geometric sequence states the following:

$s_{n} =$ Σ $a_{i} r^{i-1} = a_{1}(\frac{1-r^{n} }{1-r} )$

In this case, $r = \frac{900}{1500} = \frac{9}{15} = \frac{3}{5}$ , and $i = 10$

Therefore,

$1500( 1 + \frac{3}{5} + (\frac{3}{5})^{3} + (\frac{3}{5})^{4} + (\frac{3}{5})^{5} + (\frac{3}{5})^{6} + (\frac{3}{5})^{7} + (\frac{3}{5})^{8} + (\frac{3}{5})^{9}) = 1500( 2,4848) = 3.727, 3251$ ≈ $3.727$

Therefore, the correct answer is the option C

Grace and her father spent four and a half hours over the weekend restoring their fishing boat. This time makes up 6%of the time

anyanavicka [17]

To answer this you can use proportions.
4 1/2 6%
------- = ----
X 100%

So, 6/4.5=1.3333...
Finally, 100/1.3333... appeoximately gives you 75.
75 hours are needed to restore the boat.
Hope this helped!

Inequality, because want to know when we'll make a profit.
$d (- 680+ 960) \geqslant 52000 \\ 280d \geqslant 52000$
Profit: Let's See When 280d equals 52000

$d \geqslant \frac{52000}{280} \\ d \geqslant 185.71$
So, after 190 days Julianne will make a profit
$280(190) \geqslant 52000 \\ 53200$
