There are 7 piles of papers on a desk. Each pile has the same number of papers. There are 21 papers in all on the desk. How many papers are in each pile?

Answer:

30

24 : 28 would equal 6 : 7

[tex]6/13[/tex] x 65 = 30

Use the proportion of the bracelets

The no. of bracelets are expected to sold are 30 pieces.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given that, A jewelry store recently sold 24 bracelets and 28 other pieces of jewelry, which is 6 : 7 so, for every 6 pieces of bracelets 7 pieces of other types of jewelry are sold.

∴ No. of pieces of bracelets expected to sold are,

= 6/(6 + 7)×65.

= (6/13)×65.

= 6×5.

= 30 pieces.

Answer:

A is 1 in 100 and b is 1 in 25

Step-by-step explanation:

there are 10 digits (1, 2, 3, 4, 5 ,6 ,7 ,8 ,9, 0).

that gives you a 1 in 10 chance but there are 2 and to get both of them, you do 1 in 10 x 1 in 10 which is 1 in 100. if you know that they are both even, this limits it to a 1 in 5 twice, 1 in 5 x 1 in 5 is 1 in 25.

Answer:

1. A. 1

2. D. [tex]17^9[/tex]

Step-by-step explanation:

Properties used:

1. First, let's deal with the numerator.

[tex](17^3)^6[/tex] can be turned into [tex]17^1^8[/tex] by using the Power of a Power Property.

And then use the Product Property, [tex](17^1^8)(17^-^1^0) = 17^8[/tex]

So now, our fraction is this: [tex]\frac{17^8}{17^8}[/tex]

All number over itself in a fraction is equal to 1. But you can also do this the mathmatic way using the Quotient Property: [tex]\frac{a^m}{a^n} = a^m^-^n[/tex] or [tex]\frac{1}{a^(^n^-^m^)}[/tex]. Which then you plug the numbers in: [tex]\frac{17^8}{17^8} = 17^8^-^8 = 17^0[/tex]. And since we know that in Zero Exponent Property: [tex]a^0 = 1[/tex], we can see that [tex]17^0 = 1[/tex]. So either way, we get 1.

So the answer is 1, which is A

2. Power of a Power Property: [tex](a^m)^n = a^m^n[/tex]

So plug the numbers in the property: [tex](17^{6}) ^3[/tex]= [tex]17^1^8[/tex]

Product Property: [tex](a^m)(a^n) = a^m^+^n[/tex]

We plug the equation in with [tex](17^{6}) ^3[/tex] turned into [tex]17^1^8[/tex] ---

[tex](17^1^8)(17^-^9) = 17^1^8^-^9 = 17^9[/tex]

So the answer is [tex]17^9[/tex], which is D

The length of the car affects how fast it travels down the ramp

Step-by-step explanation:

It does not tell us the length

The length of the car affects how fast it travels down the ramp cannot be concluded by the given table.

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

The mass of the car affects how fast it travels down the ramp can be concluded from the table given.

The car with more mass will travel the fastest down the ramp can be concluded from table or data given.

The length of the car affects how fast it travels down the ramp can not be concluded by the given data as there is no length given in the table.

The car with the least mass will travel slowest down the ramp also be concluded from the data.

Hence, the length of the car affects how fast it travels down the ramp cannot be concluded by the given table.

Step-by-step explanation:

Question A: Mai pumped 10 gallons out of her pool. This meaning she is taking out water or a negative sign. She does this in a period of 5 minutes.

The expression should be:

-10 / 5 = -2 | 10 / 5 = 2

so basically either -2 or 2

Question B: Tony added 3 fish to his pond each day for 21 days.

This meaning you have to multiply 3 x 21 or add 3 twenty-one times.

3 x 21 = 63 | 3 + 3 + 3 + 3 + 3 + 3 + 3...

Either method coming to a total of 63.

reflection across axis would make the points be (4,-4)

translating five units left would make it (-1, -4)

Answer:

Answer Choice C is the closest. (**There should be a second transformation in order to get it correct look at my explanation!!**)

Step-by-step explanation:

From our information, I think C is correct.

**There is something missing for the translation**

The reason why C is the closest is that if we reflect across the x-axis, our coordinate for (4,4) would be (4,-4). Then if we went 5 units to the left, then we would get to (-1,-4) in which we have to go up 2.

Answer choices A, B, and D aren't close to (-1,-2).

The closest you'll get on this is C because as I mentioned in my explanation your stopping point would be (-1,-4) in which you need a second transformation that is 2 units up to get exactly (-1, -2).

Answer:

Step-by-step explanation:

To find the value of x, isolate it on one side of the equation.

3/4x+9=3

First, subtract by 9 from both sides.

3/4x+9-9=3-9

Solve.

3-9=-6

Rewrite the problem down.

3/4x=-6

Multiply by 4 from both sides.

4*3/4x=4(-6)

Solve.

3x=-24

Then, you divide by 3 from both sides.

3x/3=-24/3

Solve.

Divide these numbers goes from left to right.

-24/3=-8

x=-8

Variables and negative signs should appear in the answer.

I hope this helps you! Let me know if my answer is wrong or not.

Answer:

x = -8

Step-by-step explanation:

Subtract 9 both sides:

⇒ 3/4x + 9 = 3

⇒ 3/4x + 9 - 9 = 3 - 9

Simplify the L.H.S and the R.H.S:

⇒ 3/4x = -6

Use cross multiplication:

⇒ 3x/4 = -6

⇒ 3x = -6 × 4

Simplify the R.H.S:

⇒ 3x = -6 × 4

⇒ 3x = -24

Divide 3 both sides:

⇒ 3x/3 = -24/3

⇒ x = -8

Answer:

-6x - 1

Step-by-step explanation:

-3(x + 1) - (3x -2)

= -3x - 3 - 3x + 2

= -3x - 3x - 3 + 2

= -6x - 3 + 2

= -6x - 1
