Find values of x and y
A x=3.6 y=5.6
B x=7.2 y=5.9
C x= 7.2 y=6.2
D x=8 y=6

Answer:

y=2

Step-by-step explanation:

1/3 (y+7) = 3(y-1)

Multiply each side by 3 to get rid of the fraction

3*1/3 (y+7) = 3*3(y-1)

y+7 = 9(y-1)

Distribute

y+7 = 9y - 9

Subtract y from each side

y+7-y = 9y-y-9

7 = 8y -9

Add 9 to each side

7+9 = 8y-9+9

16 = 8y

Divide each side by8

16/8 = 8y/8

2 = y

Answer:

Height = 11 inches

Base = 33 inches

Step-by-step explanation:

In this question, we are asked to find the height and base of a parallelogram given the area of the parallelogram.

From the question, we are told that height is 1/3 of base. This means that base is 3 times the height

So if we represent the height with variable h, then the base is 3h

Mathematically the area of a parallelogram can be calculated by the formula

A = bh

Thus ,

363 = h * 3h

3h^2 = 363

divide through by 3

h^2 = 121

h = √121

h = 11 inches

since b = 3h , then b = 3 * 11 = 33 inches

Answer:

The total area of the logo shaded orange or blue is 66 inches^2

Step-by-step explanation:

To calculate the area shaded orange or blue, we use the formula that calculates the area of a sector since we know the angle subtended at the centre of the circle by way of the colors

Mathematically, the formula to use is ;

A = θ/360 * π * r^2

where θ represents the angle subtended at the center and r is the radius of the circle.

For the sector shaded orange, the area will be

A = 50/360 * 22/7 * 6^2 = 110/7 inches^2

For the sector shaded blue, the area will be

A = 160/360 * 22/7 * 6^2 = 352/7 inches^2

The total area shaded orange or blue is thus the addition of both areas which is mathematically equal to 352/7 + 110/7 = 462/7 = 66 inches^2

Answer:

The actual right answer is 65.94 in^2

Answer:

See below in bold.

Step-by-step explanation:

1.  21 + 2x + 29 = 180         (as supplementary angles sum to 180 degrees).

2x + 50 = 180

2x = 130

x = 65 degrees.

2. x - 36 + 73 = 180

x = 180 + 36 - 73

x = 143 degrees.

Answer:

no

Step-by-step explanation:

7²+24²=49+576=625=25²≠26²

Vertical angles are the same, so each one would be identical.

If a = 53 degrees, then angle c would also be 53 degrees.

The answer is C. 53

Answer:

mean  is 16

Step-by-step explanation:

to find the mean of the data set u add up all the numbers and then u see how many number there are in total and u divided the solution of the sum and divided it by the total number of numbers.

17+21+14+17+12+15+16 = 112

then u see how many number there are and there are 7

112/7= 16

D) The coefficient

Explanation:

The coefficient is the number placed before the variable in the expression.

In 3x x is the variable and 3 is the number placed before it making it the coefficient.

Answer:

84 dollars

Step-by-step explanation:

use x to represent the amount of money Laura had when she started shopping.

use y to represent the amount of money she had left after buying a pair of shorts.

You can create these two equations:

3/4x=y

2/3x=42

now, subsitute the value of y into the second equation.

2/3(3/4x)=42

1/2x=42

x=84

It is 3.15 x 10^-7. You find what 1.05 x 10^-10 is in scientific notation (0.00000000105), times that by 3000, and you end up with 0.000000315 (3.15 x 10^-7 is the answer)  :)

Step-by-step explanation: In a right triangle, the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse or a² + b² = c². This is called the Pythagorean Theorem.

Answer:

right, hypotenuse

Step-by-step explanation:

This is because of the pytagorean theorem

a² + b² = c²

Answer:

A square is a rhombus.

Step-by-step explanation:

A square is a geometrical figure which has four sides that are congruent. A rhombus is also a geometrical figure in which the four sides are congruent. Hence, it is true that a square is a rhombus. The difference between the two is that all the angles of a square are a right angle, while in rhombus the opposite angles are congruent.

Answer:287.6

Step-by-step explanation:

Answer:

1. The elements of  a survey include;

a. Sample

b. Questionnaire

c. Interview

d. Analysis

Only the sample is part of the survey

Step-by-step explanation:

1. a. The sample

The sample is a subset of the population of interest of the survey and the sample should be representative of the population

b. The questionnaire

The questionnaire is the document or instrument used for collecting information from the sample as such, the questionnaire determines the information sought by the researcher

c. The interview

An interview is used to obtain direct opinions pertaining to products, subjects or organization whereby a small group or sample of the population that are closely related or well vast with the subject are interviewed

d. The analysis

The collected information is analysed and the margin of error is determined after which recommendations and conclusions can be made.

2. The entire population is not part of the survey, only the sample that is part of the survey.

Answer:

The last image (The one going through points (4,1) and (8,2))

Step-by-step explanation:

If the side length is y, and the perimeter is x, x is equal to that value times 4. This means the table of points would look like this:

x     y

4     1

8     2

12    3

And so on. The only graph that is going through these points is the last one. The third graph is wrong because it's the opposite, (1,4) instead of (4,1), and the perimeter will be greater than the side length.

Answer:

14cm

Step-by-step explanation:

As we know , hexagon has six sides .

so ,

We will divide the number of sides by the total perimeter to obtain the length of one side :

_____________________

Hexagon = 6 sides .

Length of one side of hexagon would be = 84/6

=> 14 cm

Answer:

14 cm

Step-by-step explanation:

The perimeter of a regular hexagon is 84 cm. (Given)

Here,

Hexagon = 6 sides

Now,

= 84 ÷ 6

= 14 cm

Thus, the length of one side is 14 cm

Answer:

Answer:

They all add up to 1

Step-by-step explanation:

For a given probability model, when we add all possible probabilities, our answer must be equal to 1.

In a probability model, what we are trying to do is to look at all possible outcomes that can arise from using the model. All these outcomes can be seen as a fraction of the total. They each have their own percentage of occurrence.

It is when we are up all these fractions that we can get the maximum which must not be greater than 1. Thus, all probabilities of occurrence in a probability model ranges from 0 to 1, with the addition of all the probabilities equal to 1. 0 being the probability that the intended event has no probability of occurrence at all and 1 meaning it has the maximum possible probability to occur

Answer:

The value of k = -6

Step-by-step explanation:

First lets concentrate at the most obvious point, the top. Top(f) = ( 4, 1) and Top(g) = ( -2, 1).

The translation factor k ( which is called a vector ), which accounts for the trandlation of any point of f(x) --> g(x).

To translate the x coordinate of the top from 4 to -2, you have to subtract 6 of it.

Because 4 -6 = -2

Hence the factor k must be -6.

The value of k = -6
