A relationship between two quantities that is typically stated as the product of their respective quotients.

The ratio of red to blue marbles, or 6:4, is, for instance, 6:4 if a box contains six red and four blue marbles. Decimal or percentage expressions of ratios are also possible. This implies that there would be 10 children for every 16 adults.

The number of children there would be for 40 adults can be calculated by dividing 40 by 16, then multiplying the result by 10.

By using the method subtraction, Total prizes are left over are 52- 34= 18

To subtract in mathematics is to take something away from a group or a number of objects. The group's total number of items decreases or becomes lower when we subtract from it. The components of a subtraction issue are the minuend, subtrahend, and difference. An arithmetic operation called subtraction simulates the process of deleting items from a collection. The action of subtracting a matrix, vector, or other quantity from another according to predetermined rules in order to find the difference.

The tax deduction Katie paid for that week will be $78.5.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that Katie earns $549 each week working her full-time job. Her employer has a 14.3% tax deduction on all monies earned each week.

The deduction will be calculated as follows:-

Deduction = ( 549 x 14.3 ) / 100

Deduction = 7850.7 / 100

Deduction = $78.50

The correct question is given below:

A bagel shop sold 8 plain bagels and 13 rye bagels. What is the ratio of the number of rye bagels to the number of plain bagels sold?

Answer:

6 and 2

Step-by-step explanation:

Let the first and second numbers be x and y respectively.

x = 4 + y..... (1)

2x = 4 + 4y...... (2)

Using the substitution method from Eqn(1) into (2)

Anywhere we see x in Eqn(2) we substitute it with 4 + y

I. E. 2(4 + y) = 4 + 4y

8 + 2y = 4 + 4y

Collect like terms.

8 - 4 = 4y - 2y

4 = 2y

.: y = 2

Put y = 2 in Eqn(1), and we have;

x = 4 + 2

x = 6.

.: the first number is 6 and the second number is 2.

Option C is correct.

Assuming that the scores on the first exam are a representation for the ones in the second exam, we will see that the probabilities are:

First we want to get the probability that a randomly selected student gets better than a C on the second test.

We assume the percentages for the first test can be applied for the second, so, the ones that got better than a C on the first exam are:

A: 12%

B: 28%

Then the probability is:

P( more than a C) = 12% + 28% = 40% (or 0.40 in actual probability notation)

b) Now we want to find the probability of fail.

The percentage that failed the first test is:

100% - 12% - 28% - 41% - 11% = 8%

So 8% of the students failed the first exam, this means that the probability that a randomly selected student fails the second exam is:

P = 8% or 0.8 in decimal notation.

C) 12% of the students tgot an A, so the probability that a randomly selected student does not get an A is:

P = 100% - 12%  =88%

or 0.88 in decimal notation.

Minh can use unitary method to determine how many cans he will need in all to paint the 12 rooms, which will give a total of 8 cans as requirement. The tools he'll need for the same are : counters, pencil and paper.

In its simplest form, the unitary procedure is used to determine the value of a single unit from a given multiple.

How to calculate the value of one pen, for example, if 40 cost Rs. 400. To finish it, using the unitary method. Additionally, after the value of a single unit has been established, we can multiply that value by the quantity of additional units required to establish the value of the additional units.

This is typically how the concepts of ratio and proportion are used. The unitary method entails calculating the value of a single unit before calculating the value of the required number of units.

Given, He requires 2 paint cans to paint 3 rooms.

Once more, he will require 2/3 of a can of paint to paint 1 room.

yes,  the square box song big enough to fit the pizza inside.

what is square?

A square is a regular quadrilateral , which means that it has four equal sides and four equal angles.

we have that,

the diameter of the pizza is

D = 10 1/3in

the wide of the square box is

b=10.38in

we know that  

for the pizza to fit inside the box ,it must be fulfilled that

D ≤ b

convert 10.38 in to fraction number

10.38 (100/100)= 1.038/100=519/50

convert 101/3 in to an improper fraction

10 1/3 = 10+3+1/3=31/3

multiply the diameter of the pizza by 50 both numerator and denominator =31+50/50+3= 1.550/150 in

we consider here number of mailboxes is m

and m≥0

and

number of toys is t

and t≥0

Division is opposite of multiplication. If 3 groups of 4 make 12 in the multiplication, 12 divided into the 3 equal groups give 4 in each group in division. The main goal of dividing is to see how many equal groups are formed or how many are in the each group when sharing fairly.

In divisions involving fractions, numerator is called the dividend while the denominator is called the divisor while the answer is called the quotient.

Now, when Dividing decimal by a whole number, it means the decimal is the numerator while the whole number is the denominator.

The first step is to estimate quotient by approximating the dividend and divisor to the nearest compatible numbers. For example; 6.5/9

The nearest compatible number for numerator is 6 while for the denominator it is 10. Thus, we have;

7/10 = 0.7

Second step is to perform division with original numbers. This gives us;

6.5/9 = 0.722

Third step is to compare the both answers to see if our estimate makes sense.

Using compatible numbers gave us quotient of 0.7 while the normal division gave us a quotient of 0.722

Since both the quotient are very close, then it means our estimated quotient is okay.
