Please HelppppFind The Value Of X. Your Answer Must BeExact

Answers

Answer 1

Answer:

x = 8

Step-by-step explanation:

sin (30) = 4/x => solve for x.

Answer 2

Answer:

[tex]x=8[/tex]

Step-by-step explanation:

Use the sine ratio because we have the hypotenuse and side opposite the given angle to work with:

[tex]sineX=\frac{opposite}{hypotenuse}[/tex]

Insert the values:

[tex]sin30=\frac{4}{x}[/tex]

Multiply both sides by x:

[tex]x(sin30)=x(\frac{4}{x} )\\\\x*sin30=4[/tex]

Divide both sides by sin30°:

[tex]\frac{x*sin30}{sin30} =\frac{4}{sin30}\\\\x= \frac{4}{sin30}[/tex]

Insert the value of x into a calculator:

[tex]x=8[/tex]

OR:

The little red square means that angle is 90º, and the other given angle is 30°. Since every triangle has a measure of 180°, the other missing angle is 60°. The given triangle is a 30°-60°-90° triangle with the following rules:

[tex]long.leg=short.leg*\sqrt{3}\\\\hypotenuse=short.leg*2[/tex]

The hypotenuse is represented by the variable x. We are given the value of the short leg, which is 4. Solve for the hypotenuse:

[tex]h=4*2\\\\h=8[/tex]

Therefore, the value of x is 8.

:Done

Step-by-step explanation:

In the most simplest of terms, we can explain irrational numbers as numbers which cannot be expressed as a ratio of two integers usually because they cannot give an exact value when evaluated.

Using the values given :

6.7234724... - - >This is an irrational number because the '...' depicts that the values are unending and as such an exact expression in the form of a ratio (p/q) cannot be determined.

Which equation best represents the relationship
between x and y in the graph?
A. y = x + 2
C. y = 2x + 2
B. y = 2x - 2
D. y = Vzx - 2

Answers

Answer:

C y= 2x +2

Step-by-step explanation:

Look at the graph and look at the dots. For example if you look at negative 1 on the x-axis there is a dot there. so it now you count up to where you see the next dot on the y-axis. Which it goes up 2, then count to the right towards the Y-Axis which is one. now you left with 2/1. since it is going up 2 it will be positive and 2 over 1 is simplified so you are left with 2x and the B will be 2 because the line goes through 2 on the y-axis. This equation should help you y=mx+b m is the slope and B is the y axis

x°=48°

Step-by-step explanation:

angle Y=x°

angle Z= angle y, because equal side of the angles are equal.

so, angle X +angleY+ angle Z=180° ( angle sum property of triangles)

therefore 84°+x°+x°=180°

2x°=180° -84°

2x°=96°

point q is located at (18, 5). The x-coordinate of point r id half as much as the x-coordinate of point Q The y-coordinate of point r is 3 more than the y-coordinate of point q

Answers

Answer:

R (27, 8)

Step-by-step explanation:

The coordinate plane is a two-dimensional plane consisting of the y axis (vertical line) and x-axis (horizontal line). The origin is known as the zero point (reference point) is the intersection of the x axis and y axis.

A point on the coordinate plane is represented by (x, y) where x is the x coordinate and y the y coordinate.

Given point Q = (18, 5), the x coordinate is 18 and the y coordinate is 5.

Let the location of point R = (a, b)

a = x-coordinate of point Q + 1/2 of x-coordinate of point Q = 18 + (1/2)*18 = 27

b = y-coordinate of point Q + 3 = 5 + 3 = 8

Therefore R = (27, 8)

Simplify

Solve the following for the variable x.
3x - 16 = 38

Answers

Answer: x= 18

Step-by-step explanation:

3x - 16 = 38

38 + 16 = 54

3x/3 = 54/3

X= 18

Step-by-step explanation:

[tex] \tt{3x - 16 = 38}[/tex]

We want to remove the 16 first. So , Since the original equation is - 16 , we are going to use the oppsite operation and add 16 to both sides.

⟶ [tex] \tt{3x - 16 + 16 = 38 + 16}[/tex]

Simplify ! - 16 + 16 = 0 on the left. 38 + 16 = 54 on the right.

⟶ [tex] \tt{3x = 54}[/tex]

Now , we need to think how to remove the coefficient 3. Since the opposite of multiplication is division , we are going to divide both sides by 3.

⟶ [tex] \tt{ \frac{3x}{3} = \frac{54}{3}} [/tex]

Simplify ! 3 / 3 = 1 on the left and 54/3 = 18 on the right . So, our answer is 18.

[tex] \pink{ \boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \underline{ \tt{x = 18}}}}}}}[/tex]

Answers

I got this right, look....

Evidence:

Unit rate is the quantity of an amount of something at a rate of one of another quantity.

The ratios that have a unit rate greater than 1 are:

9/8 miles : 5/6 hours

4 miles : 3(1/3) hours

7 miles : 3/4 hours

What is a unit rate?

It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

9/8 miles : 5/6 hours

4 miles : 3(1/3) hours

7 miles : 3/4 hours

The unit rate of each given ratio.

9/8 miles = 5/6 hours

Multiply 6/5 on both sides.

6/5 x 9/8 miles = 1 hour

54/40 miles = 1 hour

27/20 miles = 1 hour

1.35 miles = 1 hour

4 miles = 3(1/3) hours

4 miles = 10/3 hours

Multiply 3/10 on both sides.

3/10 x 4 miles = 1 hour

6/5 miles = 1 hour

1.2 miles - 1 hour

7 miles = 3/4 hours

Multiply 4/3 on both sides.

4/3 x 7 miles = 1 hour

28/3 miles = 1 hour

9.33 miles = 1 hour

We see that,

All of them have unit rates greater than 1.

Thus,

The ratios that have a unit rate greater than 1 are:

9/8 miles : 5/6 hours

4 miles : 3(1/3) hours

7 miles : 3/4 hours

A farmer wants to make a fenced square pen. He has a total of 100 meters of fencing. He wants to determine the possibilities for the area of the pen. Let A represent the area of the pen, in square meters.

Answers

Answer:

I put B and A= 25

I got it on another website but I'm not entirely sure.

The square is asymmetrical quadrilateral, which implies it has 4 equal sides and angles. This can also be described as a rectangle having two neighboring sides that are both the same length.

It ensures that the elements are perpendicular, either at right angles to one another.

The length of the square pen is [tex]\sqrt{A}[/tex], and the perimeter should be no more than 100  then the perimeter of a square is 4a the over is [tex]a^2[/tex]  So, the equation :

[tex]\to 4\sqrt{A}=100\\\\ \to \sqrt{A}=\frac{100}{4}\\\\\to \sqrt{A}=25[/tex]

Therefore, the final answer is "25".

A line passes through the origin and has a slope of 2/3​

Answers

Answer:

y=2/3x

Step-by-step explanation:

the origin is the point (0,0) and the given slope is 2/3

the equation for slope-intercept form is y=mx+b, where m is the slope and b is the y intercept

the slope is given, meanwhile, the y intercept is the point where the line passes through the y axis, and the x value is 0.

In this question, we actually have the y intercept given, which is (0,0)

we can put it all together then:

y=2/3x+0

or

y=2/3x
