GiveN:

ABCD is a parallelogram.
AC and BD are the diagonals.
DE = 28 units

To FinD:

Value of x in length of BE?

Step-wise-Step Explanation:

We know that $,$

In any parallelogram, the diagonals (lines linking opposite corners) bisect each other. Then, AE = EC for diagonal AC and BE = DE for diagonal BD.

⇒ BE = DE

⇒ x - 4 = 28 units

⇒ x = 32 units

Hence, The required value of x here is 32 units.

Answer:

5 months

Step-by-step explanation:

y=mx+b

162.50=27.50x+25

162.50-25=27.50x+25-25

137.50=27.50x

137.50/27.50=x

5=x

Zack has a old car. He wants to sell it for 60% off the current price. The market price is $500. How much money would he receive

Snowcat [4.5K]

Zack would receive $200. You have to make 60% as a decimal= 0.60 then multiply $500*0.60= $300 then you subtract $500-$300=$200
(Hope this works!!)

Solve for y in terms of x

AnnZ [28]

-8x+ 4y= -16
4y= 8x - 16
divide it by 4
y= 2x -4
if x is 0 what is y?
y = 2 (0)-4
y = 4
just put an x value in the equation u will get your y value

1 (0,4)
2 (1,-2)
3 (2,0)
4 (3,2)
5 (4,4)

Answer:

Event 4, Event 2, Event, 3, Event 1

Step-by-step explanation:

An easy way to solve this problem is to calculate the probability of each event in this problem occurring. After doing so, one can compare the probability as a percent value and then order them from least to greatest. Remember, probability can be described as the following,

$\frac{desired\ outcomes}{possible\ outcomes}$

In this case, the equation would be written as the following,

$\frac{type \ of\ marble}{total\ marbles}$

Given

Bag A -> 9 green marbles, 11 white marbles

Bag B -> 8 green marbles, 8 white marbles

Event 1- Picking a green or white marble from Bag A.

Since there are only green and white marbles in Bag (A), there is a (100%) chance of this event happening, since there are only green and white marbles in this bag.

Event 2- Choosing a green marble from Bag A.

To solve this probability, one will need to put the number of green marbles over the total number of marbles, then convert the fraction into percent form.

$\frac{green}{green+white}\\$

Substitute,

$\frac{9}{9+11}\\\\=\frac{9}{20}$

Multiply by (5) to make the denominator (100) and convert to a percent,

$\frac{9}{20}*\frac{5}{5}\\=\frac{45}{100}=45\%$

Event 3- To solve for the probability of this event, one needs to put the number of white marbles over the total number of marbles from Bage B, then convert the fraction to a percent,

$\frac{white}{green+white}$
