What is the probability that a number selected at random integers 3 to 30 inclusive is a multiple of 3

Answer:

Another rational number

Step-by-step explanation:

Here, we want to get the type of number that should be added to a rational number to explain that the sum of two rational numbers is rational

What we simply have to do here is to add another rational number to the rational number we have already

By adding another rational number to the rational number we have, we will get another rational number

That has successfully proven what we are trying to prove

Answer:

6 Flower hats

Step-by-step explanation:

If you are asking for whole number answers, then the answer is 6 Flower hats.

check:

6X27=162 and 4 plain hats, 4X22=88, 162+88=250.

hope it helps!

The required number of hats with flowers is 6.

Given that,
Scooter the clown buys flower hats for $27 each and plain hats for $22 each. If he spends a total of $250 on hats, how many hats have flowers is to be determined.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
let the hat with flower be x and the plain hats be y,
Total number of hats = 10
x + y = 10 - - - - - (1)
According to the question,
27x + 22y = 250 - - - - -(2)
Solving equation 1 and 2
gives
x = 6 and y = 4

Thus, the required number of hats with flowers is 6.

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Sales discount = 10%

If original price of items = p

Hence, the sales price of the item can be represented as :

(100% - percentage discount) * sales price

(100% - 10%) * p

90% * p

0.9p

B.)

(1) By subtracting the offered percentage discount (10%) from the full percentage cost (100%) and then multiplying the result by the original cost of the item.

(11.) by obtaining discount amount (10% of the original price) , and then subtracting the discounted amount from the original price of the item.

Answer:

16 kg

Step-by-step explanation:

Mass = (5x - 4) kg

Unit Price = 3x/kg

Total Price = mass * unit price

Total Price = (5x - 4)kg * 3x/kg

Total Price = 15x^2 - 12x

Total Price = 192

15x^2 - 12x = 192

15x^2 - 12x - 192 = 0

5x^2 - 4x - 64 = 0

ax^2 + bx +c = 0

ac = 5(-64) = -320

ac = -20 * 16

-20 + 16 = -4

5x^2 - 20x + 16x - 64 = 0

5x(x - 4) + 16(x - 4) = 0

(x - 4)(5x + 16) = 0

x - 4 = 0   or   5x + 16 = 0

x = 4   or   5x = -16

x = 4   or   x = -3.2

x cannot be negative because it would give a negative unit price, so we discard the negative answer.

x = 4

mass = 5x - 4 = 5(4) - 4 = 20  4 = 16

Answer: 16 kg

Answer:

a) 3/5=12/20

b) 5/6=25/30

Step-by-step explanation:

a.) To find the answer you would first find how much it took to get to 20. 5  times 4 is 20. Then to find the numerator you would do 3 times 4 and that would be 12.

b) To find the answer you would first find how much it took to get to 30. So 30/6 is 5. Then you would divide 25 by 5 and you would get 5.

Step-by-step explanation:

let's combine like terms first to simplify the equation

we need to only combine the variables with the same variable.

3a+5a would make 8a

and 4b+10b would be 14b

but we cannot combine 8a and 14b

so the equation remains as 8a+14b

Final Answer: [tex]8a + 14b[/tex]

Steps/Reasons/Explanation:

Question: Simplify [tex]3a + 4b + 5a + 10b[/tex].

Step 1: Collect like terms.

[tex](3a + 5a) + (4b + 10b)[/tex]

Answer:

They contributed $8

Step-by-step explanation:

Given

[tex]Savings = \$40[/tex]

Proportion of savings: [tex]Parent = \$1[/tex]   [tex]You = \$4[/tex]

Required

Determine your parent contribution

From the question, we understand that, they contribute $1 when you save $1.

This means that the unit savings is:

[tex]Unit = \$4 + \$1[/tex]

[tex]Unit = \$5[/tex]

The parent contribution is then calculated as:

[tex]\frac{Parent\ Proportion}{Unit\ Savings} * Total\ Savings[/tex]

[tex]= \frac{\$1}{\$5} * \$40[/tex]

[tex]= \frac{1}{5} * \$40[/tex]

[tex]= \frac{1* \$40}{5}[/tex]

[tex]= \frac{\$40}{5}[/tex]

[tex]= \$8[/tex]

Hence, they have contributed $8

Answer:

430 peaches

Step-by-step explanation:

Calculation for How many Peaches did he have to start

Using this formula

Peaches at hand=Remaining Peaches/(100%-Percentage of peaches sold)

Let plug in the formula

Peaches at hand=280/(100%-35%)

Peaches at hand=280/65%

Peaches at hand=430 peaches

Therefore the numbers of Peaches he have to start with is 430 peaches

Step-by-step explanation:

Rachel's cost = $35x + $15  

Taylor's cost = $25x + $75

When are the costs equal? Rachel's cost = Taylor's cost?

35x + 15 = 25x + 75

35x - 25x = 75 - 15

10x = 60

x = 6

Check Rachel's 6 month cost is: 35 x 6 + 15 = 225

Check Taylor's 6 month cost is 25 x 6 + 75 = 225
