Answer: 45%

Step-by-step explanation: There's 9 people over the age of 14. And 9 divided by the total number, 20, gives you 0.45. 0.45 multiplied by 100 is 45.

Answer:

The independent variable is the number of miles you walked.

Unfortunately, I do not know the dependant variable.

Step-by-step explanation:

Dependent variable is distance from home (y)

Independent variable is number of miles walk (x)

Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is equal.

According to questions,

x represents the number of miles have walked

y represents distance from home in miles.

The relationship between these two variables can be expressed by the following equation: y=x+5

The dependent variable is that whose value changes whenever the value of the independent variable is changed.

From the equation above:

When x=2, y=2+5=7 miles

When x=4, y=4+5=9 miles

We can clearly see that y changes for different values of x.

Hence, dependent variable is distance from home (y)

Independent variable is number of miles walk (x)

Answer:

x=7

y = 4

Step-by-step explanation:

Since it is a parallelogram

2x-2 =12

and 2y =8

2x-2=12

Add 2 to each side

2x-2+2 =12+2

2x = 14

Divide by 2

2x/2 =14/2

x = 7

2y =8

Divide by 2

2y/2 =8/2

y =4

Answer:

x = 7

y = 4

Step-by-step explanation:

To find the values of x and y, you need to set them equal to its congruent pair. On the parallelogram, you can see that there are two pairs of sides that are the same length, so set them equal to one another, like so:

2x - 2 = 12

Add 2 to both sides:

2x = 14

Divide 2 by both sides:

x = 7

Solving for y:

2y = 8

Divide both sides by 2:

y = 4

Answer:

To find the area of a rectangle multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area. This is the same as saying length2 or length squared.

Step-by-step explanation:

Answer:

For a rectangle, you get the length and width and multiply them

For a Square, you have to find one side length and mulitply it by itself

or you can split the square with a diagonal into 2 triangles, get the area of each and add them up

or split the square in half and find the area of both rectangles and then add them together

Step-by-step explanation:

For example, if the measure of one side of a square is 5, because all the other lengths are the same, you do 5 times 5 which equals 25 or 5^2 which is 25

Answer:

itsc c (0,3) ,d(3,0)

Step-by-step explanation:

If AB is divided into three equal parts then coordinates of C is  (0, 3) and D coordinates are (3, 0)

A system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space.

Divide AB into three equal parts

[tex]X_{c}-X_{a}=\frac{1}{3} (X_{B}-X_{D})[/tex]

=3

[tex]Y_{a}-Y_{c}=\frac{1}{3} (Y_{A}-Y_{B})[/tex]

=3

So C is (0, 3)

[tex]X_{B} -X_{D} =\frac{1}{3} \times 9[/tex]

=3

[tex]Y_{D} -Y_{B} =\frac{1}{3} \times 9[/tex]

=3

So D coordinates are (3, 0)

Hence, if AB is divided into three equal parts then coordinates of C is  (0, 3) and D coordinates are (3, 0)

Answer: 28

Step-by-step explanation: Follwing PEMDAS, add the 3 and 5 in the parentheses first. You get 8, then multiply by 3, which gives you 24. Add 4 to 24 and it will give you 28.

Answer:

If i'm not mistaken, using PEMDAS which is parenheses, exponents, multiplication, division, adding and subtracting, the answer will be 28.

Step-by-step explanation:

3+5=8

8 * 3= 24

24 + 4= 28

Answer:

1 3/5

Step-by-step explanation:

Flip the small triangle around to make it look like the big triangle. Find the ratio between triangles (2/5 = .4). .4 is the ratio. Multiply 4 (the side corresponding with x) by .4. You will get 1.6. 1.6 is the same as 1 3/5.

Answer:

600

Step-by-step explanation:

10 times 10 is 100. A cube has 6 sides. 6 times 100 is 600

Answer:

10 x 10 = 100 so the area of 1 side is 100

there is 6 sides and the surface area is all the areas added up

100 x 6 = 600

the surface area is 600

Answer:The Correct answer is C) the summation from n equals one to 6 of quantity negative 7 minus 3 times n

Step-by-step explanation:

The given Arithmetic sequence: −10, −13, −16, …

Theory : For arithmetic sequence : a, a+d,a+2d......a+(n-1)d

Formula for summation is given as Sn =

Where, a=  First term of sequence = (-10) and d= difference of any two consecutive terms = (a+d)-(a) = (-13)-(-10)= (-3)

Putting values in Summation formula

Sn =

Sn =

Sn =

Sn =

Thus, Correct answer is C) the summation from n equals one to 6 of quantity negative 7 minus 3 times n

72% of students chose burritos

Step-by-step explanation:

first you would add up the total of kids that said they liked the other two options, which was pizza and sandwiches: 10+4=14

then you would take that number and subtract it from the total of all students: 50-14=36

and then you would take that number and divide it by 50: 36/50=.72

turn that into a percent and you'd get 72%
