Find the circumference of the given circle given a diameter of 40 cm.
Use 3.14 as an approximation of TT
40 cm

Answer:

what is the question

Step-by-step explanation:

Step-by-step explanation:

In this question as two straight lines intersect each other

we use vertically opposite angle axiom

so 74 degree = 2x.

then x= 74/2= 37degree

Answer:

Angle 74 degrees and 2x are vertical, so they would have to equal each other.

Note: Vertical angles are congruent meaning they measure the same degrees

So we set up the equation;

74 = 2x

/2     /2

37° = x

Answer:

3x-x+2=4

Step-by-step explanation:

You replace y in the problem with 5 so you have 4x+3*5=8 then you multiply 3*5 and 15 then rewrite your problem so it looks like 4x+15=8 then add 15 to the side with the 8 so it looks like 4x=23 then divide 23 by 4 and you get x.

Answer:

y = 3/4x + 5

-3x + 4y = 20

Step-by-step explanation:

In order to write this equation, you need the slope and y-intercept (I'll answer in slope-intercept form and standard form)

First change that standard form equation to slope-intercept form:

1. 4x + 3y = 8

2. 3y = -4x + 8

3. y = -4/3x + 8/3

Step 1 is given.

In step 2, 4x was subtracted from both sides.

In step 3, both sides were divided by 3.

Slope-intercept form:

y = mx + b

m is the slope and b is the y-intercept.

m = 3/4; the slope of a line perpendicular to another line is the negative reciprocal of the other line's slope (ex: line's slope is 1/4; a line perpendicular to it has a slope of -4, the negative reciprocal)

b = 5; the y-intercept was stated in the problem

Now, you put it together: y = 3/4x + 5

Standard form:

You can just change the slope intercept form back into standard form by moving the numbers around a bit:

1. y = 3/4x + 5

2. -3/4x + y = 5

3. -3x + 4y = 20

Step 1 is given.

In step 2, 3/4x was subtracted from both sides of the equation.

In step 3, both sides were multiplied by 4 so that the equation could have nice whole numbers. (this step is optional, I just think it's easier to read this way)

Answer:

Team 1 -- 7

Team 2 -- 6

Step-by-step explanation:

The range is the difference between the highest and lowest values in a set of numbers. To find it, subtract the lowest number in the distribution from the highest.

Answer:

1. A=18

2. A= 48

Step-by-step explanation:

1. Area = 1/2 x base x height

The base is 9 and the height is 4

1/2 x 9 x 4= 18

2. Area = L x W

The length is 12 the width is 4

12 x 4 = 48

Step-by-step explanation:

Answer:

distance: 14

explanation:

[tex]\sf \sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]

given:

solve:

[tex]\sf \rightarrow \sqrt{(5-5)^2+(6--8)^2}[/tex]

[tex]\sf \rightarrow \sqrt{(0)^2+(14)^2}[/tex]

[tex]\sf \rightarrow \sqrt{14^2}[/tex]

[tex]\sf \rightarrow 14[/tex]

Solution:

We know that:

[tex]\text{Distance }=\sqrt{(x_2-x_1)^{2} +(y_2-y_1)^{2}}[/tex]

Finding the coordinates

Substitute the coordinates into the distance formula.

[tex]\text{Distance }=\sqrt{(x_2-x_1)^{2} +(y_2-y_1)^{2}}[/tex]

[tex]\rightarrow \text{Distance }=\sqrt{[(6- (-8)]^{2} +[5-5]^{2}}[/tex]

[tex]\rightarrow \text{Distance }=\sqrt{[(6 + 8]^{2} +[0]^{2}}[/tex]

[tex]\rightarrow \text{Distance }=\sqrt{[14]^{2}[/tex]

[tex]\rightarrow \boxed{\text{Distance }=14 \ \text{units}}[/tex]

Answer:

your answer is 9,42

Step-by-step explanation:

This is because if you follow the pattern:

5,38

6,39

7,40

8,41

9,42

so (9,42) is your answer

Answer:

Frieda should substitute 42 for z in the original equation, and simplify to see if it is a true statement. 42 + 22 = 64, so her solution is correct

Step-by-step explanation:

Answer:

it is the same on the other side

Step-by-step explanation:

1 step out the g where the other g is on the line it is on but other side

2 put x on same line with y but other side
