What is the area of the circle below? (Use 3.14 for Pi)

A. 31.4 square cm
B. 15.7 square cm
C. 78.5 square cm
D. 157 square cm

Answer:

  a.  (-1, 3)

Step-by-step explanation:

The "glide" 4 units right and up is the transformation ...

  (x, y) ⇒ (x+4, y+4)

The reflection across y=1 is the transformation ...

  (x, y) ⇒ (x, 2-y)

Combined, you have the transformation ...

  (x, y) ⇒ (x +4, 2-(y +4)) = (x +4, -2-y)

Then, ...

  K(-5, -5) ⇒ K'(-5 +4, -2-(-5)) = K'(-1, 3)

120 yd^3

Step-by-step explanation:

The formula for the volume of a pyramid is...

[tex]V=\frac{1}{3}Bh[/tex]

B is the area of the base and h is the height from the middle of the pyramid to the top. Since we know both of these we can plug them in.

[tex]V=\frac{1}{3}(45*8)[/tex]

[tex]V=\frac{1}{3}*360[/tex]

[tex]V=[/tex]

120

The volume for the pyramid is 120 yd^3.

Answer:

120 yards ^3

Step-by-step explanation:

To solve we need to know the formula.

The formula for the volume of a pyramid is  1/3 B * H

B= 45 and H = 8. We can sub those values in to the formula to solve.

= 1/3 45*8

= 1/3 360

=120

Since we multiplied yd^2 by yd, we get yd^3

So the answer is 120 yd^3

Answer:

g = 28

Step-by-step explanation:

g/2 + 7 = 21

Subtract 7 on both sides.

g/2 = 21-7

g/2 = 14

Multiply 2 on both sides.

g = 2(14)

g = 28

Answer:

Solution,

[tex] \frac{g}{2} + 7 = 21 \\ or \: \frac{g + 7 \times 2}{2} = 21 \\ or \: \frac{g + 14}{2} = 21 \\ or \: g + 14 = 42(cross \: multiplication) \\ or \: g = 42 - 14 \\ g = 28[/tex]

Answer:

x=−5

Step-by-step explanation:

Steps:

Step 1 to 4 : Simplify

Steps 5: Calculating the Least Common Multiple

Steps 6: Calculating Multipliers

The correct answer for this question is x=−5

Answer: x=−5

Hope this helps.

Answer:

x = -5

Step-by-step explanation:

2/3 - 1/x = 13/15

Subtract 2/3 from each side

2/3 -2/3 - 1/x = 13/15 -2/3

-1/x = 13/15 - 2/3

Getting a common denominator

-1/x = 13/15 -2/3*5/5

-1/x = 13/15 - 10/15

-1/x = 3/15

Using cross products

3x = -15

Divide each side by 3

3x/3 = -15/3

x = -5

Answer:

P=96;A=540

Step-by-step explanation:

To find the perimeter, the distance around the pool, all you need to do is add 18+18 then add 30+30. Why? Because assuming the pool is a rectangle, it would have 4 sides. The two width sizes as 18 and the two lengths as 30. Now, finding the area is even simpler. All you have to do is multiply the width by the length. 18*30.

Answer:

About 5.5% decrease

Step-by-step explanation:

Here, we want to calculate the percentage increase or decrease and its value.

The first thing to do here is to check if we are going to have a decrease or an increase.

since the value before the change is higher than the value after the change, then what we have is a decrease.

Mathematically, the percentage decrease is calculated as follows;

% decrease = (old value - new value)/old value * 100%

old value = 163 feet

new value = 154 feet

% decrease = (154-163)/163 * 100%

% decrease = -9/163 * 100%

% decrease = -5.52%

Thus the best answer is about 5.5% decrease

11. y = -5x+2

12. y=41

13. y=2x+3

14. y= -4x-39

Step-by-step explanation:

y= -2(x-3)

y= -2x+6

10.

12x+30y=10

Subtract 12x from both sides

30y=10-12x

Divide both sides by 30

y= -0.4x+ [tex]\frac{1}{3}[/tex]

11.

y = -5x+2

12.

y=6+36-1

y=41

13.

y-3=2x

Add 3 to both sides

y=2x+3

Answer:

105 seconds

Step-by-step explanation:

To solve this, we can set up an equation.

First, let's find how far ahead Jillian is.

15*6=90

Jillian is 90 feet ahead.

Let's name the time that Samantha walks x.

7x is the distance Samantha walks.

90+6x is the distance Jillian walks.

We want to find how many seconds they have walked when the distance is equal.

So let's form an equation.

7x=90+6x

Subtract 6x from both sides.

x=90

Samantha needs to walk 90 seconds.

Jillian started 15 seconds before that.

90+15=105

Jillian had been walking for 105 seconds when the two girls had walked the same distance.

Answer:

3rd choice

Step-by-step explanation:

Answer:Of the 600 people who visited the Amazing Art Museum on Tuesday, 45% were children.

How many children visited the museum on Tuesday?

To solve the problem, we can write the

percent

as

a  

ratio

and then create an  

equivalent ratio

.

On Tuesday,  

270

children visited the museum.

The number of children visited the museum on Tuesday will be 270.

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.

Given that;

Total number of people = 600

And, There are 45% were children.

Now,

Since,  45% were children.

Hence, The number of children = 45% of 600

                                                  = 45/100 × 600

                                                  = 45 × 6

                                                  = 270

Thus, There are 270 children.

Length of the shorter piece of board is equals to 5foot.

" Length is defined as the distance between two end points of any object."

According to the question,

Length of the board = 13foot

'l' represents the length of the longer piece

As per the condition given we have,

Length of the shorter piece = [tex]\frac{l}{2} +1[/tex]

Therefore,

[tex]l + \frac{l}{2}+1=13[/tex]

⇒ [tex]\frac{3l}{2} =13-1[/tex]

⇒[tex]l= \frac{2}{3} (12)[/tex]

⇒ [tex]l= 8foot[/tex]

Length of the shorter piece = [tex]\frac{8}{2} +1[/tex]

                                              = [tex]5foot[/tex]

Hence, length of the shorter piece of board is equals to 5foot.

Answer:

121800, 591.09375, 1/4.

Step-by-step explanation:

I have attached the work to your problem.

Please see the attachment below.

I hope this helps!

Answer:

4. 121800

5. 591.09375

6. 0.25

Step-by-step explanation:

4. It's an AP with:

first term(a): 12

common difference(d): 24-18 = 6

Sn = (n/2)(2a + (n-1)d)

S200 = (200/2)[2(12) + (200-1)(6)]

= 121800

5. It's an GP with:

first term(a): 12

common ratio(r): 18/12 = 1.5

Sn= a(r^n -1)/(r-1)

S8 = 12(1.5⁸-1)/(1.5-1)

= 18925/32 = 591.09375

6. It's an infinite GP with:

first term(a) = 1/12

common ratio: 1/18 ÷ 1/12 = ⅔

Sinfinity: a/(1-r)

= (1/12) ÷ [1-⅔]

= 1/12 ÷ 1/3

= 1/12 × 3

Answer:

see explanation

Step-by-step explanation:

(1)

Given

g(r) = (r + 14)² - 49

To obtain the zeros, let g(r) = 0 , that is

(r + 14)² - 49 = 0 ( add 49 to both sides )

(r + 14)² = 49 ( take the square root of both sides )

r + 14 = ± [tex]\sqrt{49}[/tex] = ± 7 ( subtract 14 from both sides )

r = - 14 ± 7, then

r = - 14 - 7 = - 21 ← smaller r

r = - 14 + 7 = - 7 ← larger r

(2)

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

g(r) = (r + 14)² - 49 ← is in vertex form

with vertex = (- 14, - 49 )
