A regular hexagon has sides that are all congruent and angles that all measure 120 degrees. This means the angles of a regular hexagon add up to 720 degrees. ... An irregular hexagon has sides that are not the same measurement and can have points facing inward as well as outward.

Please help me with this -2 - (-0.7)
Amanda [17]

Anytime you subtract a negative number, it changes it to adding a positive number.

-2 + 0.7

Since we are adding, we will have an arrow going to the right

-2 + 0.7 = -1.3

Therefore, we will have a point starting at -2, an arrow pointing to the right and stopping at -1.3

Best of Luck!

Suppose a video store charges non-members $4 to rent a video. A membership costs $21 and then videos cost only $2.50 to rent. Ho
densk [106]

Answer:

You need to rent  14  videos, and you'll pay the same amount for both. Renting 15 will make the membership a better method of payment.

Step-by-step explanation:

Let Number of videos to be rented be x;

Given:

For non members;

Cost of renting 1 video = $4

Cost for renting x videos = 4x

For Members;

Membership cost = $21

Cost of renting 1 video =  $2.50

Cost of renting x video =  2.5x

We can create an equation. Say the number of videos you rent is given by x . We can write that, if we rent  x  videos without membership, we'll have to pay 4x . If we rent the same amount of videos with membership, we'll have to pay 21+2.5x.

Hence the equation can written as

4x=21+2.5x\\4x-2.5x=21\\1.5x=21\\x=\frac{21}{1.5}=14

Hence You need to rent  14  videos, and you'll pay the same amount for both. Renting 15 will make the membership a better method of payment.

Two coins are tossed simultaneously 500 times, and we get
andrew11 [14]
The probability of 2 heads:
105:500

This can be simplified further. If you divide them both by 5, you get:

21:100

That is the answer, as it cannot be simplified any further.

The probability of one head:
275:500

This can be simplified further. If you divide them both by 25, you get:

11:20

That is the answer, as it cannot be simplified any further.

The probability of no heads:
120:500

This can be simplified further. If you divide them both by 20 you get:

6:25

That is the answer, as it cannot be simplified any further.

So:
a) 21:100
b) 11:20
c) 6:25
