You just need to move the decimal to the right however many times there is a zero in the number. For example, for number 35, you would move it to the right once to get 0.9 because there is one zero in the 10. Does this make sense?

Four usual dice are thrown on the ground. The total of numbers on the top faces of these four dice is 13 as the top faces showed

The total of the faces touching the ground is 15.

<h3 /><h3>What is probability?</h3>

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.

Given that:

Four usual dice are thrown

Total of numbers on the top faces of these four dice = 13

we know that in a dice, the sum of the numbers on any two opposite faces is always 7.

So,1 is opposite 6,

2 is opposite 5

and 3 is opposite 4.

Now, when 4,3,1 and 5 are the numbers on the top faces, then 3,4,6 and 2 respectively are the numbers on the face touching the ground as they sum upto 7.

Hence, total o faces touching the ground =3+4+6+2=15.

Plese help me with 5 math questions! 50 points and brainliest! But don't type anything in the answer box until pics are posted!!

lukranit [14]

1. $x-5\ \textgreater \ 2$

add 5 to both sides

$x\ \textgreater \ 3$

2. $x+2\ \textless \ -5$

subtract 2 from both sides

$x\ \textless \ -7$

3. $x-2\ \textless \ 2$

add 2 to both sides

$x\ \textless \ 4$ and it's the 4th graph option

4. $x+5 \geq 10$

subtract 5 from both sides

$x \geq 5$ and it's the 2nd graph option

5. $x-5\ \textgreater \ -10$

add 5 to both sides

$x\ \textgreater \ -5$

Answers:

1. 3rd option

2. 1st option

3. 4th option

4. 2nd option

5. 2nd option

A sign language club made $627. 50 from selling popcorn at a festival. The popcorn cost the club $95. 0. Which expression repres

solmaris [256]

The expression representing the amount of money that was raised for each member of the club is $\dfrac{627.50 - 95.0}{m}$ (in dollars)

<h3>How to interpret the division? </h3>

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.

Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.

Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.

Thus, $a \div b = a$ divided in b equal parts.

Also, we can write: $a \div b = a \times \dfrac{1}{b}$

(it is since $a = a \times 1$ so $a/b = 1 \times (a/b) = (1/b) \times a$ )

<h3>How to find the profit earned?</h3>

Profit earned is the extra money which we make after deducing the cost price of the process we're doing.

So, we get:

Profit earned = Total amount earned - Amount spent initially for preparation to earn

P = Selling price (S.P.) = Cost price (C.P.)

For the given case, we're given that:

Amount made by the sign language club by selling popcorn at a festival = $627.50
The cost price for the popcorn to the club = $95.0

The money raised = Amount made by selling popcorn - amount costed to the club for getting popcorn

Money raised = $627.50 - $95.0

If it is given that: m = number of members in the considered club, then:

Money each member of the considered club will get = Money raised divided in equal m parts = $\dfrac{627.50 - 95.0}{m}$ (in dollars)

(we don't write symbols like of currency generally, and understand it from context.)

Thus, the expression representing the amount of money that was raised for each member of the club is $\dfrac{627.50 - 95.0}{m}$ (in dollars)
