Answer:

20%

Step-by-step explanation:

% increase = (final − initial) / initial × 100%

= (30 − 25) / 25 × 100%

= 20%

Answer:

The percent gain is 25%

Step-by-step explanation:

Answer: $10

Step-by-step explanation:

Angie buys = 1 software package and 1month of gameplay.

Kenny buys = 1 software package and 2 months of game play.

Cost of each software package = $30. Total cost = ​$90​

The total cost is the addition of what Kenny and Angie bought. This will be:

(1 SF + 1 G) + (1 SF + 2 G) = 90

where,

SF = software package = 30

G = game

(1 SF + 1 G) + (1 SF + 2 G) = 90

30 + 1G + 30 + 2G = 90

60 + 3G = 90

3G = 90 - 60

3G = 30

G = 30/3

G = 10

One month of game play cost $10

Answer:

mars is 140 times farther than the moon

Step-by-step explanation:

hope this helped :-)

Answer:

6x^2+11x+3

Step-by-step explanation:

Area= Length*Width

Area= (3x+1)(2x+3)

Use method FOIL (Front,Out,In,Last)

(3x*2x)+(3x*3)+(2x*1)+(3*1)

= 6x^2+9x+2x+3

Simplify:

6x^2+11x+3

Answer:

Step-by-step explanation:

(-8-4)/(5+3)= -12/8= -3/2

perp. 2/3

y - 4 = 2/3(x + 3)

y - 4 = 2/3x + 2

y = 2/3x + 6

y - 4 = -3/2(x + 3)

y - 8/2 = -3/2x - 9/2

y = -3/2x - 1/2

Answer:

Zeke had a 2.17% margin of error in his estimation.

Step-by-step explanation:

To set this problem up, you would need to create a proportion. X, the percent of error you're trying to find, should be over 100%. It should look like:

2/92 = X/100

This would translate your terms, the distance the football was kicked, into percentage terms. You should have 2/92 rather than 90/92. 90/92 would give you how accurate Zeke's estimate was instead of is percent of error.

Cross-multiply your numbers:

(2)(100) = 92X

200 = 92X

X = 2.1739

Then, once you round it, your answer would be X = 2.17.

Answer:

9. Perpendicular

10. neither

11. Perpendicular

12. neither

Step-by-step explanation:

------------------

Slope Intercept Form: y = mx + b

* M is the slope

* B is the y intercept

------------------

Lines are parallel if they have the same slope (ex. If two equations have a slope of 2)

Lines are perpendicular if they have the opposite and the reciprocal slope (ex. If 1 equation has a slope of 3 and another equation has a slope of - [tex]\frac{1}{3}[/tex] )

------------------

9. Perpendicular: The slopes are reciprocal of each other and one of them is negative

10. Neither: The lines are not perpendicular because the slopes are both negative

11. Perpendicular: If you plot y=5 it is a horizontal line through 5. If you plot x=-3 it is vertical line through -3. These lines intercept and are perpendicular.

12. Neither: The slopes of both equations need to be the same to be parallel

Answer: 8.484%

Step-by-step explanation:

The formula for percentage error is calculated as:

= (actual value observed - expected value) / expected value × 100

where,

Actual value observed = $480.00

Expected value = $524.50

Percent error = ($480.00 - $524.50)/$524.50 × 100

= -$44.50/$524.50 × 100

= -0.08484 × 100

= -8.484

= 8.484%

Answer:

0.8944

Step-by-step explanation:

We start by calculating the z-score

To calculate the z-score, we shall need the standard deviation

Mathematically, standard deviation is square root of variance

that will be; SD = √108,900 = 330

Formula for z-score is;

x-mean/SD/√n

where n is 65 in this case

z-score = (3882-3831)/330/√65 = 1.25

The probability we want to calculate is;

P( X < 1.25)

we can use the standard normal distribution table for this

Using the table;

P( X < 1.25) = 0.89435 which is 0.8944 to 4. decimal places

0.8944

Answer:

195 students are left-handed

Step-by-step explanation:

Here, we want to calculate the total number of students who are left-handed

Let the total number of students in the school be x

The total ratio is 8 + 3 = 11

8/11 * x = 520

8x = 11 * 520

x = (11 * 520)/8

x = 715 students

So the number of students who are left handed will be;

Total - number of right-handed students

That would be;

715-520 = 195

Answer:

[tex]820.681 = 8 \times 10^2 + 2 \times 10^1 + 6 \times 10^{-1} + 8 \times 10^{-2} + 1 \times 10^{-3}[/tex]

Step-by-step explanation:

[tex]820.681 = 8 \times 100 + 2 \times 10 + 6 \times 0.1 + 8 \times 0.01 + 1 \times 0.001[/tex]

[tex]820.681 = 8 \times 10^2 + 2 \times 10^1 + 6 \times 10^{-1} + 8 \times 10^{-2} + 1 \times 10^{-3}[/tex]

The answer is D

The equation that can be used to determine the number of years at which the trees will be an equal height is -

14x + 12 = 16x + 2

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] → is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] → is the y - intercept i.e. the point where the graph cuts the [y] axis.

We have Sara owns a tree farm. Variety A of a pine tree is shipped to her at 12 inches tall and grows at a rate of 14 inches per year. Variety B of a pine tree is shipped to her at 2 inches tall and grows at a rate of 16 inches per year.

Variety [A] = 14x + 12

Variety [B] = 16x + 2

The equation that can be used to determine the number of years at which the trees will be an equal height is -

14x + 12 = 16x + 2

Therefore, the equation that can be used to determine the number of years at which the trees will be an equal height is -

14x + 12 = 16x + 2

Answer:

[tex]y = \frac{1}{3}x - 5[/tex]

Step-by-step explanation:

Given

[tex]slope\ (m) = \frac{1}{3}[/tex]

[tex]y\ intercept = -5[/tex]

Required

Determine the line equation in slope intercept

The equation of a line in slope intercept is:

[tex]y = mx + b[/tex]

Where

[tex]m = slope = \frac{1}{3}[/tex]

[tex]b = y\ intercept = -5[/tex]

So, [tex]y = mx + b[/tex] becomes

[tex]y = \frac{1}{3}x - 5[/tex]
