Since they share the same angle measurement, and 4 is smaller than 158 degrees, you subtract 158 from 180 and angle 4 = 22 degrees

Natasha2012 [34]

Answer:

8:16, 8 actions films

Step-by-step explanation:

1:2 = 1x:2x

= 24 / (1x+2x)

= 24 / 3x = 8, x = 8

= 8*1 : 8*2

= 8:16

Proof:

8 + 16 = 24

Rolex buys computer disks at a price of 4 for $5 and sells them at a price of 3 for $5. How many computer disks must he sell to
Lina20 [59]

Given that Rolex buys computer disks at a price of 4 for $5 .

That means cost price of 1 disk = 5/4


Given that Rolex sells them at a price of 3 for $5.

That means selling price of 1 disk = 5/3


Profit on 1 disk = selling price - cost price

Profit on 1 disk = \frac{5}{3}-\frac{5}{4}

Profit on 1 disk = \frac{5}{3}\cdot\frac{4}{4}-\frac{5}{4}\cdot\frac{3}{3}

Profit on 1 disk = \frac{20}{12}-\frac{15}{12}

Profit on 1 disk = \frac{5}{12}

Now we have to find how many disk to be sold to get the profit $100

so we just divide $100 by profit on 1 disk

\frac{100}{\left(\frac{5}{12}\right)} = 100\cdot\frac{12}{5} = 240

Hence final answer is 240 disks.

What additional information could be used to prove that ΔXYZ ≅ ΔFEG using ASA or AAS? Check all that apply.
Maksim231197 [3]

Answer: ∠Z ≅ ∠G and XZ ≅ FG or ∠Z ≅ ∠G and XY ≅ FE  are the additional information could be used to prove that ΔXYZ ≅ ΔFEG using ASA or AAS.

Step-by-step explanation:

Given: ΔXYZ and ΔEFG such that ∠X=∠F

To prove they are congruent by using ASA or AAS conruency criteria

we need only one angle and side.

1. ∠Z ≅ ∠G(angle) and XZ ≅ FG(side)

so we can apply ASA  such that ΔXYZ ≅ ΔFEG.

2. ∠Z ≅ ∠G (angle)and ∠Y ≅ ∠E (angle), we need one side which is not present here.∴we can not apply ASA  such that ΔXYZ ≅ ΔFEG.

3. XZ ≅ FG (side) and ZY ≅ GE (side), we need one angle which is not present here.∴we can not apply ASA  such that ΔXYZ ≅ ΔFEG.

4. XY ≅ EF(side) and ZY ≅ FG(side), not possible.

5. ∠Z ≅ ∠G(angle) and XY ≅ FE(side),so we can apply ASA  such that

ΔXYZ ≅ ΔFEG.

Dafna1 [17]
We know that
<span>The quotient of
-8x</span>²y³/xy=-8xy²

then 
<span>the product of
(4xy)*z= -8xy</span>²------> z=-8xy²/(4xy)-----> z=-2y

the answer is
-2y
so
The quotient of -8x²y³/xy is same as the product of (4xy)*(-2y)
