Answer:

It increased by 33.696

Step-by-step explanation:

I took the test, :D-|--=:

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.

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 :)

Answer:

11x11= 1

1/2x11x10x4

=220

121+220=341

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 values that are in the correct spots are: 82, 62, 163 and 300

Step-by-step explanation:

There are 144 boys in total. We know that 82 attended the fall fling, so if we do 144-82 we know that 62 boys attended the spring social, therefore the vaules 82 and 62 are in the correct spots. We know that out of 156 girls, 75 attended the spring social. 156-75=81. The values 75 and 81 are in the wrong spots, therefore they are not correct.

82 boys + 81 girls at the fall fling = 163 total students at the fall fling, therefore 163 is also in the correct spot.

62 boys + 81 girls at the spring social = a total of 137. The chart says the total is 143 which is incorrect.

156 total boys plus 144 total girls = 300 total students, therefore 300 is in the correct spot.

Answer:

y = -5x - 3

Step-by-step explanation:

To answer this the slope must be clculated first

slope equation:

[tex]\frac{y2-y1}{x2-x1}[/tex]

these variables symbolize ordered pairs, and the best part is that you can use any two ordered pairs for this example we can use (-5, 10) and (-3,0)

we'll call the first ordered pair 1 so x1 = -5 and y1 = 10.

the next odered pair is 2 so x2 = -3 and y2 = 0.

With this information layed out we can solve:

[tex]\frac{0-10}{-3-(-5)}[/tex]

0 - 10 = -10

-3 - (-5) = 2 --- remember negatives cancel each other out to make a positive

[tex]\frac{-10}{2}[/tex] = -5

the slope of the line is -5. Now the next thing to note is that one of the ordered pair (-3,0) is a y intercept. It's time to introduce the equatione of a line:

y = mx+b

There are other equations that can be used for a line but with the info given this equation best suits the data.

m = slope

y and x = are the ordered pair you can input into the equation to slove

b = the y intercept

So the equation would be:

y = -5x - 3

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

5x5x3.14= 78.5 square units

Answer:

angle 2=120°

angle 1=60

Step-by-step explanation:

70+50=120

or

180-(70+50)=60

angles on a straight line add up to 180°

180-60=120

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.

#SPJ2

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

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

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.
