If the radius of a circle is 2.6 inches, what is the diameter of the circle?

Answer:

1) should be B

2) should be C

Step-by-step explanation:

Answer:

B, 3 8/9

Step-by-step explanation:

It all comes down to equivalent fractions.

2 1/3 as an improper fraction is 7/3.

1 5/9 as an improper fraction is 14/9. 1/3 = 3/9.

With that being said 7 x 3 = 21 resulting in 21/9.

14/9 + 21/9 = 35/9.

35/9 as a mixed fraction is 3 8/9.

Answer:

Volume = 646.0 cm³

Step-by-step explanation:

The solid is made up of a hemisphere and a cube

Therefore,

Volume of the composite solid = ⅔πr³ + a³

Where,

r = ½(8) = 4 cm

a = 8 cm

Plug in the values

Volume of the composite solid = ⅔*π*4³ + 8³

= 134.04 + 512

= 646.0 cm³ (nearest tenth)

Answer:

The area of the rectangle ABCD will be 8 sq. units.

Step-by-step explanation:

The rectangle shape ABCD has vertices A(- 2,2), B(6,2), C(6,3) and D(- 2,3).  

Presently, length of side AB = [6 - (- 2)] = 8 units.  

{Since the line AB is corresponding to the x-pivot, so the length of the portion AB will be the contrast between the x-directions of the focuses An and B}  

Once more, line BC is corresponding to y-pivot and thus the length BC = (3 - 2) = 1 units.  

Subsequently, the space of the square shape ABCD will be (8 × 1) = 8 sq. units. (Answer)

Use the distance formula to see if all three sides are congruent.

Step-by-step explanation:

An equilateral triangle is a triangle which has three sides with the same lengths. If we check for congruence we are checking to see if all the sides are the same :)

To prove a triangle is an equilateral triangle by using  the distance formula to see if all three sides are congruent, the correct option is C

Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.

Given;

To prove a triangle is an equilateral triangle

Now, we have to use the distance formula: d = sqrt( (x2 - x1)² + ( y2 - y1 )²)

When 2 sides are congruent it could be a scalene triangle, so it is not enough. All 3 sides must be congruent.

Therefore, the answer will be by use the distance formula of triangle to see if all three sides are congruent.

Answer:

[tex]A=24[/tex]

Step-by-step explanation:

For finding the area of a trapezoid you first have to use the correct formula which is  [tex]A=\frac{1}{2}(b_1+b_2)h[/tex].

Now we plug in what we already know.

[tex]A=\frac{1}{2}(b_1+b_2)h\\A=\frac{1}{2}(5+7)(4)[/tex]

Now we start with the parenthesis

[tex]A=\frac{1}{2}(12)(4)[/tex]

Now if you can, you can multiply the 1/2 and the 12 and the 4 using a calculator or mentally

Answer:

17. a  18. c   19. d   20. b

Step-by-step explanation:

Hello, for the first question, you just take the person with the largest number and the person with the smallest number. Kenny (5) and Sammy (0).

For question 18, you just add up all the numbers like this:

0+1+3+5+4+1+1+2+1= 18

And then you divide it by the number of people there which is 9:

18/9=2

For question 19, you arrange all the numbers from least to greatest like this:

0,1,1,1,1,2,3,4,5

And then you count on both ends until it meets the middle. 1 is the middle.

For the last question, you just find the number that appears the most, which is one.

Answer:

B. 658 Hours

Step-by-step explanation:

All you do is divide.

$19 for every hour, it's 2 persons so,

$38 for every hour.

so,

25,000/38

= 657.894736842 which is about 658 so,

= 658 Hours

It would take 658 hours for the robot to pay for itself in labor savings

An equation is an expression that shows the relationship between two or more numbers and variables.

The robot can replace two people doing assembly work that are paid $19 per hour.

Let us assume it would take x hours for the robot to pay for itself in labor savings

(19 + 19)x = 25000

38x = 25000

x = 657.9

It would take 658 hours for the robot to pay for itself in labor savings

h = x = -(-4) / (-2)

h = x = -4/2

h= x = -2

For x = 0:

3x - y = 4

0 - y = 4

y = -4

For x = 1

3x - y = 4

3 - 3 - y = 4 - 3

The equation of the line in point-slope form is [tex]y - 1 = m(x + 1)[/tex]

Step-by-step explanation:

Equation of a line:

The equation of a line, in point-slope form, is given by:

[tex]y - y_0 = m(x - x_0)[/tex]

In which the point is given by [tex](x_0,y_0)[/tex] and m is the slope.

The slope of the line below is 3.

This means that [tex]m = 3[/tex]

(-1,1)

This means that [tex]x_0 = -1, y_0 = 1[/tex].

Equation of the line:

[tex]y - y_0 = m(x - x_0)[/tex]

[tex]y - 1 = m(x - (-1))[/tex]

[tex]y - 1 = m(x + 1)[/tex]

The equation of the line in point-slope form is [tex]y - 1 = m(x + 1)[/tex]
