25% of 12 is 3 so just add that to the original value

Answer:

$15

Step-by-step explanation:

Multiply the cost by the percentage mark up

12 × 25%

Convert the percentage into a decimal

12 × 0.25

3

Add the mark up to the original price

12 + 3

15

Answer: x = 10

Step-by-step explanation: 4 times 250 is 1000 and divided by 100 is 10

Answer:

20. 1/2 and 5/7 so the chance would be 5/14 or 20.83

19. 5/7 and 1/2 so it's 5/14 or 20.83 again

18. 2/7 and 11/1 so it's a 22/7 chance or 3.14

Step-by-step explanation:

ahh this is a really tough one  :D  Does this happen to be an AP math class,  Pineapple    .. you are in advanced math :O.... good for you  :)

sooo what can we set equal

note the lines  have the same lenght, therefore the arc length will also be the same,  then they give us the other two lengths to make the entire circle , yay

so then just set all the arc lengths equal to 360 °

(3x+ 30) + (3x + 30 ) + 2x + 4x = 360  ( put like terms together )

12x +  60 = 360    ( subtract 60 from both sides )

12x = 300   ( divide both side by 12 )

x = 25

nice we now know X  :)

Answer:

1.641× 10^-3 pounds/ cubic inch

Step-by-step explanation:

Density= mass / volume

Mass of the material= 9 kilograms

Volume= 7 cubic feet

Density= 9/7= 1.286 kg/ ft^3

Density= 1.286 kg/ ft^3

To Convert to pounds per inch

1 kg/ ft^3 = 0.00128 pound / cubic inch

1.286 kg/ ft^3 = X pounds/ cubic inch

X=( 1.286 × 0.00128)

= 0.0016407087 pounds/ cubic inch

= 1.641× 10^-3 pounds/ cubic inch

Hence,this density in pounds per inch is 1.641× 10^-3 pounds/ cubic inch

Answer:

The average rate of change over the given interval is 12

Step-by-step explanation:

Here, we want to calculate the average rate of change over the given interval

Mathematically, we can calculate the average rate of change using the formula below;

f(b) - f(a)/b-a

The f values are same as the y values

Thus, we have it that;

a = 1 and b = 3

f(a) = -5 and f(b) = 19

The average rate of change is thus;

(19-(-5))/(3-1) = 24/2 = 12

Answer:

13

Step-by-step explanation:

Evaluate the expression for v = 2.

First, plug in 2 wherever v is seen.

5v + 3

5(2) + 3

Next, multiply.

5(2) + 3

10 + 3

Add.

10 + 3

13

Your final answer is 13.

Please let me know if there are any issues with this answer.

Answer:

i think this is algebra

Step-by-step explanation:

The first thing you have to do is open the multiplication parenthesis to substitute V for 2

5v + 3

5 (2) + 3

Now that you have the parenthesis, you multiply and then the result that you add.

5(2) or 5x2= 10 but is better with parenthesis.

10 + 3

=3

Answer:

f(x)=x+2

Step-by-step explanation:

Pick any two points from the question and plug them into the equation y2-y1/x2-x1. In this case, I picked (0,2) and (1,3). Therefore, the equation will be   3-2/1-0. Simplify this to get 1/1 which is equal to 1. Therefore, the slope is equal to 1. Then pick a point and plug it into the point  slope form equation which is y-y1=m(x-x1) where m is the slope. In this case, I picked (0,2). Therefore, the equation will be y-2=(x-0). Simplify this to get y-2=x. You want to isolate y so you have to add 2 to both sides. This will make the equation y=x+2 which is the answer. Therefore, the answer is y=x+2 or f(x)=x+2.

Macie waters 5 plants. She uses [tex]\frac{2}{3}[/tex] cup of water for each plant. So, she uses 3.33 cups of water. This problem is based on the principle of multiplication.

The principle of multiplication states that a number when multiplied by another number results in a product of the two numbers. These two numbers on being multiplied give a unique number and that resultant number is said to be divisible by both numbers and their factors.

It is given that Macie waters 5 plants.

According to the question, she uses [tex]\frac{2}{3}[/tex] cup of water for each plant.

Total number of cups of water used by her [tex]= 5\times\frac{2}{3}[/tex]

                                                                        [tex]= \frac{10}{3}[/tex]

                                                                        [tex]= 3.33[/tex].

So, Macie uses 3.33 cups of water.

Answer:

1.344

Step-by-step explanation:

Given that:

n=49,σ = 4.8

Zcritical = 95%

Using the relation :

Margin of Error = Zcritical * sqrt(σ² / n)

Zcritical at 95% = 1.96

Margin of Error = 1.96 * sqrt(4.8² / 49)

Margin of Error = 1.96 * (4.8 / 7)

Margin of Error = 1.96 * 0.6857142

Margin of Error = 1.344
