Which of the following steps were applied to ABCD to obtain A'B'C'D

Step-by-step explanation:

the answer is in the above image

======================================================

Explanation:

The diameter 32 cuts in half to 16, which is the radius. So r = 16.

Use this to find the surface area of the sphere in the formula below

SA = 4*pi*r^2

SA = 4*pi*16^2

SA = (4*16^2)*pi

SA = 1024pi

This is the exact surface area in terms of pi.

The area units are in square feet, or ft^2 for short.

Answer:

D

Step-by-step explanation:

The question states you need a square. That means whatever you do, must leave a square number like 49 or 64

If you add 6 or 7 to 56  you do not get 64    A and C are both wrong.

If you subtract 7 from 56 you get 49 which is a perfect square and all 4 sides will equal 7.

Answer:

Step-by-step explanation:

We know that the equation of a circle is:

(

x

−

a

)

2

+

(

y

−

b

)

2

=

R

2

where a and b are the coordinates of the center, and R is the radius.

So in this question we have to complete the squares:

x² + y² - x - 2y - 11/4 = 0       ->

x² - x + 1/4 + y² - 2y = 11/4 +1/4     ->

(x - 1/2)² + y² - 2y + 1 = 12/4 + 1     ->

(x - 1/2)² + (y - 1)² = 4

Therefore, the coordinates of the center are C = ( 1/2, 1) and the Radius is R = 2

      x² + y² - x - 2y - 2³/₄ = 0

               x² + y² - x - 2y = 2³/₄

               x² - x + y² - 2y = 2³/₄

(x² - x + 1) + (y² - 2y + 4) = 2³/₄ + 1 + 4

             (x - 1)² + (y - 2)² = 7³/₄

The coordinates for center of the circle is equal to (1, 2). The coordinates of the length of the radius is √(³¹/₄).

Answer:

the answer is 0.40 and 0.12 children have much greater chance of having side effects than adults mark me brainiest

Step-by-step explanation:

The correct option is P(side effects | child) = 0.40 and P(side effects | adult) = 0.12. Conclusion is Children have a much higher chance of having side effects than adults.

Total number of people tested = 100

Number adults = 50

Number of adults who got side effects = 6

Probability that the adult got side effects = 6/50 = 0.12

Number of children = 50

Number of children who got side effects = 20

Probability that the children got side effects = 20/50 = 0.40

Here, it is clear that probability that the children got side effects is greater than that adult got side effects.

So, Children have a much higher chance of having side effects than adults.

An average horse weighs 900-2,000 pounds, depending on size and breed. A lean, racing fit Thoroughbred, for example, has an average weight of 900-1,100 pounds, while the average Clydesdale (think Budweiser) weighs in at 1,800-2,000 pounds

Answer:

If one horse will weigh about 2000 pounds, or 1000kg, then four horses will weigh about 8000 pounds or 4000kg

Answer:

[tex]7 + a = \sqrt{7b + c}[/tex] --- equation

[tex]a = 3; b =5\ and\ c = 65[/tex] --- the equation is true for these values

[tex]a = 4; b=5\ and\ c = 10[/tex] --- the equation is extraneous for these values

Step-by-step explanation:

Given

[tex]x +2 = \sqrt{3x + 10[/tex]

[tex]x + a = \sqrt{bx + c}[/tex]

Solving (a): Equation to solve for a, b and c, using trial by error where [tex]x = 7[/tex]

We have:

[tex]x + a = \sqrt{bx + c}[/tex]

Substitute 7 for x

[tex]7 + a = \sqrt{7b + c}[/tex] --- This is the equation

Solving (b): Solve for a, b and c --- to make the equation true

[tex]7 + a = \sqrt{7b + c}[/tex]

Let a = 3 ----- Here, we choose a value for a

[tex]7 + 3 = \sqrt{7b + c}[/tex]

[tex]10 = \sqrt{7b + c}[/tex]

Square both sides

[tex]100 = 7b + c[/tex]

Let b = 5 --------- Here, we choose a value for b

[tex]100 = 7*5 + c[/tex]

[tex]100 = 35 + c[/tex]

Subtract 35 from both sides

[tex]c = 65[/tex]

So, [tex]x + a = \sqrt{bx + c}[/tex] is true for

[tex]a = 3; b =5\ and\ c = 65[/tex]

Solving (b): Solve for a, b and c --- to make the equation false

[tex]7 + a = \sqrt{7b + c}[/tex]

Substitute [tex]a = 4; b=5\ and\ c = 10[/tex]

So, we have:

[tex]7 + 4 = \sqrt{7*5 + 10}[/tex]

[tex]11 = \sqrt{35 + 10}[/tex]

Square both sides

[tex]121 = 45[/tex] --- This is false

i.e.

[tex]121 \ne 45[/tex]

Answer:

Part A: 9 times

Part B: 79%

Step-by-step explanation:

Part A:

Volume of the large pan = πr²h

Where,

radius (r) = ½(diameter) = ½(12) = 6 in.

height (h) = 3 in.

Volume = π*6²*3

Volume of the large pan = 339.29 in.³

Volume of the small pan = πr²h

r = ½(4) = 2 in.

h = 3 in

Volume of small pan = π*2²*3

Volume of the small pan = 37.7 in.³

✔️To determine how many times the volume of the large pan is greater than the small pan, divide the volume of the larger by the smaller:

= 339.29/37.7 ≈ 9

✅The volume of the large pan is about 9 times greater than the volume of the smaller pan.

Part B:

✔️Find the volume of the box:

Volume of box = L*W*H

Where,

L = 12 in.

W = 12 in.

H = 3 in.

Volume of the box = 12*12*3 = 432 in.³

Divide the volume of the large pan over the volume of the box and multiply by 100%

Thus:

339.29/432 × 100

= 78.5393519 ≈ 79%

The large cheesecake takes up about 79%

3 consecutive even integers are 8, 10, 12

8 + 10 + 12 = 30.

Answer:

8, 10 ,12

Step-by-step explanation:

Let x be the first integer

x+2 is the second

Step-by-step explanation:

Given :

Now,

5.01×10-3 ? 0.00105

50.1-3?0.00105

From the above equation, we can say that 47.1  is greater than 0.00105

Therefore, 47.1 > .00105

Answer:

s = 20

Step-by-step explanation:

Given

3 = - 2 | 0.25s - 5 | + 3 ( subtract 3 from both sides )

0 = - 2 | 0.25s - 5 | ( divide both sides by - 2 )

0 = | 0.25s - 5 | , then

0.25s - 5 = 0 ( add 5 to both sides )

0.25s = 5 ( divide both sides by 0.25 )

s = 20

Answer: S=20

Step-by-step explanation:

Data: 3=-2(0.25s-5)+3

S=?

Step one, Multiply .25s and -5 by -2

-2x0.25s=-0.50s

-2x-5=10

Reason: When something is in parenthesis, that is the first thing you evaluate, and since -2 is right next to the parenthesis, you multiply both numbers by -2 to get -.50s and 10

Step two, add like terms

3=-.50s+10+3=3=-.50s+13

Reason: When there are like terms(terms with the same variable or same exponent, etc.) You have to add them or else evaluating things will get harder to do as you go on, in this case, the two like terms(3 and 10) added together get 13.

Step three, subtract 13 on both sides

3-13=-.50s+13-13

-10=-.50s

Reason: Because the point of this is to single out 's', you have to get rid of the 13 and since it's a positive 13, you add it to a negative to cancel it out, but what you do to one side you do to the other so you subtract 13 from 3 to get negative 10.

Step four, divide -.50 on both sides

-10/-.50=-.50s/-.50

S=20

Reason: Since you have to isolate 's' and it's right next to -.50(which means multiplication), you have to divide it to get rid of it. Since what you do to one side you do to the other, you divide -10 by -.50 to get 20=S

That's how you get the answer

I hope this helps!

Answer:y=x-5

Step-by-step explanation: Use (y2-y1)/(x2-x1) fill those in and get (4-1)/(9-6) which is 3/3 and that is 1 for the slope. Now fill in y=1x with a given coordinate and try to find the y-intercept so we would do 1=1(6) and we need to make the right side equal to the left so we subtract 5. Ending us with y=x-5.
