=220

121+220=341

Answer:

10

Step-by-step explanation:

The current probability of picking a red ball is [tex]\frac{x}{15}[/tex]. When 5 more balls are added, the probability is 3/4. We can write a ratio for this problem:

[tex]\frac{x+5}{15+5} = \frac{3}{4}[/tex]

When using cross multiplication to solve this, you get 3 * 20 = 4(x+5).

60 = 4x + 20

40 = 4x

x = 10 red balls

Step-by-step explanation:

your welcome and pls give me the brainliest

Let's simplify these ratios:-

1. 3:9

Divide both sides by 3:-

1:3

 2. 9:27

Divide both sides by 9:-

1:3

  3. 2:4

Divide both sides by 2:-

1:2 (Option C)

 4. 30:90

Divide both sides by 30:-

1:3

Hope everything is clear; if you need any explanation/clarification, kindly let me know, and I will comment and/or edit my answer :)

first I start with 1 and multiply 2 =2 and add 1 =3

so on

start with 40 divided by 2 =20+4=24

The sum total of the sequence would be 45, using the two steps given.

This refers to the use of mathematics to solve equations and letters represent numbers.

Although your sequence is incomplete because it only gave two steps, I would work with only those steps.

Hence, if the first number is 1,

Multiply by 2, 1 x 2= 2

DIvide by 2, 2/2= 1

Add 4, starting from 40.

1+44= 45.

Answer:

50⁰

Step-by-step explanation:

we know that sum of angles in a triangle is equal to 180⁰

on adding the angles we get

x⁰+x⁰+20⁰+x⁰+70⁰=180⁰

3x⁰+90⁰=180⁰

3x⁰=90⁰

x⁰=30⁰

Now angle R=x+20=30+20=50⁰

Answer:The difference between the medians is 2.5

Step-by-step explanation: So how I did this is first I found the median of the two plots (median=the middle number in a group of values) so anyway I lined it all out because I find it easier to do it that way (20,25,25,30,30,30,30) so the answers I got for both plots were -plot A=32.5 and plot B=30 than difference means subtract so 32.5-30=2.5

angle 2=120°

angle 1=60

Step-by-step explanation:

180-(70+50)=60

angles on a straight line add up to 180°

180-60=120

Answer:

x = 40

Step-by-step explanation:

(3x + 5) + (x + 15) = 180

3x + 5 + x + 15 = 180

Answer:

35

Step-by-step explanation:

Steps

1.  5x + 105 = 8x because you distributed the 5

2. 105 = 3x because you subtract the 5x on both sides

3. 105/3 = x because you divide the 3 and 105/3 is 35

Step-by-step explanation:

Answer:

B, C, and E

The reason B, C, and E are the answer's is because the equation of a linear equation is y= mx+b. B, C, and E are written this way. We can eliminate A and D because They are quadratic equations, because the X is squared.

Answer:

a - 30.5

b - 31

c - 31

d - 2

Step-by-step explanation:

Mean is average:

31,29,31,30,31,30,31,31,30,31,30,31

366/12

30.5

Median is the middle of the data points.

Line data points up in order from least to greatest.

29,30,30,30,30,31,31,31,31,31,31,31

12/2=6

Since there is an even amount data points the median is the mean of the two middle data points:

Middle data points: 31,31

31

Mode is the most common data point.

It would be 31.

Range is highest point subtracted by lowest point.

Answer:

b

Step-by-step explanation:

first, figure out the radius. the radius is the 1/2 of the diameter, so 5. in the equation, the formula is pi x radius^2. so 5^2 is 25. then 25x3.14 is b, and we have our answer.

Answer:

b

Step-by-step explanation:

10 divided by 2=5 radius

to get area = Radius^2 x pi

Answer:

2,379 & look below for remaining numbers

Step-by-step explanation:

The divisor 4 goes to the left of the whole box, because you are dividing all the numbers by 4.

So for the last box, 4 x 9 = 36

For the top of the 3rd box, it's 4 x ? = 280, so you do 280 divided by 4 = 70

For the 2nd box, 4 x 300 = 1200

For the 1st box, I did the problem of 9516 divided by 4 in long division form.  4 goes into 9 only 2 times & the 2 is in the thousands place.  So on top of the 1st box goes 2,000 & in the box goes 4 x 2,000 = 8,000.

Add 8,000 + 1,200 + 70 + 36 = 9,516

9,516 divided by 4 = 2,379

2,000 + 300 + 70 +  9 = 2,379

Answer: The division is a method of distributing a group of things into equal parts. It is one of the four basic operations of arithmetic, which gives a fair result of sharing.

The division is an operation inverse of multiplication. If 3 groups of 4 make 12 in multiplication; 12 divided into 3 equal groups give 4 in each group in division.

The main goal of the division is to see how many equal groups or how many in each group when sharing fairly.

For example:

There are 16 balls and 4 boxes, how to put 16 balls into four equal sized boxes?

Step-by-step explanation:  Therefore, 4 balls should be kept in each box.

Mathematical notation for division

There are various signs which can be used to indicate division such as ÷, /.

For example:

8 ÷ 2

8/2

Special names for each character in Division

Each part involved in a division equation has a special name.

Dividend ÷ divisor = quotient

Dividend: The dividend is the number that is being divided in the division process.

Divisor:The number by which dividend is being divided by is called divisor.

Quotient: A quotient is a result obtained in the division process.

 18    ÷   3    =    6

image5       image4       image6

Dividend        divisor         quotient

So, in the above process where we divided 16 balls into 4 equal groups;

The dividend is 16, the divisor is 4 and thus the quotient is 4.

Answer:

Step-by-step explanation:

There are three main parts to a division problem: the dividend, the divisor, and the quotient. The dividend is the number that will be divided. The divisor is the number of “people” that the number is being divided among. The quotient is the answer.
