Answer:

a = 8 2/3.

Step-by-step explanation:

The y coordinate of the point is 5, andthe x coordinate is a so substituting for these in the given equation:

3a - 4(5) = 6

3a  - 20 = 6

3a = 26

a = 26/3

= 8 2/3

[tex]\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}[/tex]

here , we've been given a point with coordinates ( a , 5 ) and an equation ( 3x - 4y = 6 ).

Coordinate geometry deals with parameters related to points over cartesian plane , where a points , say G , has two coordinates x and y.

the coordinates are written as ( x , y ) , where x is the x coordinate or abcissa and y is the y coordinate or ordinate.

for getting the solution to the question asked , let us think of x as a and y as 5.

Now ,

substituting the values of x and y in the equation ,

[tex]3x - 4y = 6 \\ \implies \: 3(a) - 4(5) = 6 \\ \implies \: 3a - 2 = 6 \\ \implies \: 3a = 6 + 20 \\ \implies \: 3a = 26 \\ \implies \: a = \frac{26}{3} [/tex]

let's once check , if we've arrived at the correct result or no.

This can be done , by putting value of x as [tex]\frac{26}{3}\\[/tex] which is the value of a.

So ,

[tex]3x - 4y = 6 \\ \\ \implies \: \cancel3 (\frac{26}{\cancel3} ) - 4(5) = 6\\ \\ \implies26 - 20 = 6 \\ \\ \implies \: 6 = 6[/tex]

hence , verified !

Therefore ,

[tex]\bold\red{a = \frac{26}{3} }\\ [/tex]

The volume of a pyramid is given by the formula ...

  V = 1/3Bh

where B is the area of the base.

__

The base is shown as a right triangle with legs 8 cm and 7 cm. Its area is given by the triangle formula ...

  A = 1/2bh

  A = 1/2(8 cm)(7 cm) = 28 cm²

Then the volume of the triangular pyramid is ...

  V = 1/3(28 cm²)(9 cm) = 84 cm³

Answer:

Option B, [tex]396\ units^2[/tex]

Step-by-step explanation:

Step 1:  Determine the area of the bottom

[tex]A = l * w[/tex]

[tex]A = 12\ units * 8\ units[/tex]

[tex]A = 96\ units^2[/tex]

Step 2:  Determine the area of the back

[tex]A = l * w[/tex]

[tex]A = 9\ units * 8\ units[/tex]

[tex]A = 72\ units^2[/tex]

Step 3:  Determine the hypotenuse

Pythagorean theorem → [tex]a^2 + b^2 = c^2[/tex]

[tex]12^2 + 9^2 = c^2\\[/tex]

[tex]144 + 81 = c^2[/tex]

[tex]225 = c^2[/tex]

[tex]\sqrt{225} = \sqrt{c^2}[/tex]

[tex]15 = c[/tex]

Step 4:  Determine the area of the top

[tex]A = l * w[/tex]

[tex]A = 15\ units * 8\ units[/tex]

[tex]A = 120\ units^2[/tex]

Step 5:  Determine the area of the triangles

[tex]A = \frac{h\ *\ b}{2}[/tex]

[tex]A = \frac{9\ units\ *\ 12\ units}{2}[/tex]

[tex]A = \frac{108\ units^2}{2}[/tex]

[tex]A = 54\ units^2[/tex]

Step 6:  Determine the surface area

[tex]96\ units^2 + 72\ units^2 + 120\ units^2 + 2(54\ units^2)[/tex]

[tex]396\ units^2[/tex]

Answer: Option B, [tex]396\ units^2[/tex]

The marginal relative frequency for the people who do not like cantaloupe is 0.455.

This refers to the addition of the joint relative frequencies in a row or column of a data table.

Hence, we would make a representation of the table from the result of the survey of 200 random people is:

                              Watermelon      Not watermelon    Total

Cantaloupe                  93                       16                         109

Not cantaloupe           66                       25                         91

Total                           159                       41                          200

So, the marginal relative frequency for the people who do not like cantaloupe is 0.455.

The average monthly temperature in New Orleans, LA  varies on average about 43.5°F from its monthly mean temperature.

Suppose the data specified is of n sized as

[tex]x_1, x_2, \cdots , x_n[/tex]

Let this data's mean be  [tex]\bar{x}[/tex]

Then, the mean absolute deviation of this data is the mean of the absolute differences of the observations from the mean of the data they belong to.

It is calculated as:

[tex]M.A.D = \dfrac{\sum_{i=1}^n|x_i-\bar{x}|}{n}[/tex]

So, Mean Absolute deviation is the average of the deviation (not caring if its above or below the mean) of the data values.

Since it is given that:

Mean absolute deviation of the temperatures (monthly) in New Orleans = 43.5°F, therefore, it means, the temperature averagely varies  43.5°F from its monthly average value.

where mean shows the average monthly temperature in New Orleans, LA.

Thus, the average monthly temperature in New Orleans, LA  varies on average about 43.5°F from its mean temperature.

The glass part of the frame is an illustration of fractions

The width of each side of the frame is 5 1/4 inches

The given parameters are:

Represent the width of each side with x.

So, we have:

Glass part + 2x = Total width

Substitute known values

31 1/2 + 2x = 42

Subtract 31 1/2 from both sides

2x = 10 1/2

Divide both sides by 2

x = 5 1/4

Hence, the width of each side of the frame is 5 1/4 inches

Step-by-step explanation:

As the two triangles are similar, the value of x = 10.

Answer:

B

Step-by-step explanation:

One easy way to solve this (considering it's on paper) would be to just plot the points of each option (because a rectangle is a quadrilateral which is equiangular (right angles) and a parallelogram).
Another way to solve this is the fact that it's angles are right angles. This means that a point has to be on the line y=5 and another point has to be on the line y=1. This means that the y coordinates of the other two points has to be 5 or 1, making the only possible answer B.

The payment for sessions makes a series

This series is GP with the first term of 5 and common ratio of 5.

The nth term would be

Use the equation above and find the 7th term

Answer:

[tex]a_7=5(5)^{6}[/tex]

78125 dimes

Step-by-step explanation:

The given scenario can be modeled as a geometric sequence.

A geometric sequence has a common ratio (multiplier) between each term, so each term is multiplied by the same number.

General form of a geometric sequence:

   [tex]a_n=ar^{n-1}[/tex]

where:

Given:

Therefore, a = 5

Given:

Therefore, r = 5

Substitute these values into the formula to create an equation for the nth term.

[tex]\implies a_n=5(5)^{n-1}[/tex]

To find the number of dimes he will pay after 7 sessions, simply substitute n = 7 into the found equation:

[tex]\implies a_7=5(5)^{7-1}[/tex]

[tex]\implies a_7=5(5)^{6}[/tex]

[tex]\implies a_7=5 \cdot 15625[/tex]

[tex]\implies a_7=78125[/tex]

Therefore, the friend will pay 78125 dimes after the 7th study session.
