Solve for a side in right triangles

Answer:

x = 4

Step-by-step explanation:

(6x - 3)° = (2x + 13)° are vertical angles that equal each other get x by itself and solve for x.

(6x - 3)° = (2x + 13)°

6x - 2x = 13 + 3

4x = 16

x = 4

Substitute x for the angles.

(6x - 3)° = ?

(6*4 - 3)° = ?

(24 - 3)° = 21°

(2x + 13)° = ?

(2*4 + 13)° = ?

(8 + 13)° = 21°

Answer:

Answer:

42 students in total

Step-by-step explanation:

we could surmise that the question wishes to find the minimum number of students who had been in Mr. Jone's algebra class, so we let 'x' represent the original count of students in the class and we have the following inequality:

14 <= x/3

x >= 42

the class had no less than 42 students

Answer:

[tex]19 \frac{1}{2} [/tex]

Step-by-step explanation:

[tex] \frac{3}{10} \times 65 = \frac{3}{10} \times \frac{65}{1} = \frac{195}{10} = 19.5 = 19 \tfrac{1}{2} [/tex]

The required simplified value of the given product is a mixed value 19 1/2.

Given that,
To determine the product write the product as a whole number or a mixed number 3/10 × 65.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Given expression,
= 3/10 × 65
= 195/10
= 19.5
=19 1/2

Thus, the required simplified value of the given product is mixed value 19 1/2.

Answer:

25 percent; each section of the box plot counts as 25%

The value of percentage of the data values are between 90 and 110 is,

⇒ 50%

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Given that;

The box-and-whisker plot below represents some data set.

Now, We get;

Range of data set = 130 - 90

                            = 40

Hence, The value of percentage of the data values are between 90 and 110 is,

⇒ (110 - 90)/40 x 100

⇒ 20/40 x 100

⇒ 50%

Thus, The value of percentage of the data values are between 90 and 110 is,

⇒ 50%

Step-by-step explanation:

Add 3y to both sides

6x-3y- 15 + 3y =0+3y

Simplify

6x- 15 =3y

Add 15 to both sides

6x-15 + 15 =3y + 15

Simplify

6x =3y+ 15

Divide both sides by6

6x/6= 3y/6+ 15/6

x=y+5/2

Answer:

122 miles

Step-by-step explanation:

Let n = number of miles driven

Given:

⇒ 14.95 + 0.95n = 130.85

Subtract 14.95 from both sides:

⇒ 0.95n = 115.90

Divide both sides by 0.95

⇒ n = 122

Therefore, he drove 122 miles.

The number that indicates the extent of a region on a plane or a curved surface is known as area. The total surface area of this triangular prism is 1,782 cm².

The number that indicates the extent of a region on a plane or a curved surface is known as area. The area of a plane region or plane area refers to the area of a form or planar lamina, whereas the area of an open surface or the border of a three-dimensional object is referred to as surface area.

The given figure has two rectangles and two triangles, therefore, the total surface area can be written as,

[tex]\rm Total\ Surface\ Area =\text{Surface area of rectangle1} + \text{Surface area of rectangle2} + (2 \times \text{Surface area of triangle})\\[/tex]

Substitute the dimensions we will get,

[tex]\rm Total\ Surface\ Area =( 25 \times 30)+ (24 \times 25) + (2 \times \dfrac12 \times 18 \times 24)[/tex]

                              [tex]\rm = 750+600+432\\\\=1,782\ cm^2[/tex]

Hence, the total surface area of this triangular prism is 1,782 cm².
