What is the circumference of the circle below? (Round your answer to the nearest tenth)

Given data,

The square on the right is a scaled copy of square on left

Here, we want to get the scale factor

Define Scale factor :

Scale Factor is used to scale shapes in different dimensions. In geometry, we learn about different geometrical shapes which both in two-dimension and three-dimension. The scale factor is a measure for similar figures, who look the same but have different scales or measures.

To get the scale factor, we divide corresponding sides by each other

That, we have that,

                              = (19/2) / 19

                              = 9.5 / 19

                              = 0.5                    (see image)

Therefore,

The scale factor is 1 to 0.5

Answer:

1/4

Step-by-step explanation:

o=area of first square

t=area of second square

o=19*19

o=361

t=19/2 * 19/2

t=19*19/(2*2)

t=361/4

t=o * x

361/4=361*x

x=1/4 ==> scale factor

Answer:

Area of the shaded region 85 square inches

Step-by-step explanation:

10(width)x8(height)=80

Triangle on the right= (8x5)/2=20

Triangle on the left=(8x5)/2=20

Both triangles' area=40

80+40=120

Not shaded area=5x7=35

120-35=85

Answer:

3, 5.38, 66, V21

Step-by-step explanation:

I assumed that V was the roman numeral V, which is equivalent to the number 5. I then multiplied 5 by 21 which is 105. If this is not the case and they simply wanted us to replace the v with a 5, then the answer would still be correct because 521 is greater than all the numbers in this set. Hope this helps.

Answer:

D.

Step-by-step explanation:

Its a fifth degree function so it will have 5 roots.

One of the 3 roots is complex ( imaginary):-  4 + i so there must be another root value 4 - i because these roots always occur as conjugate pairs.

The fifth root must be real because you cant have just one imaginary root.

Answer: 3x^2+16x-12

Step-by-step explanation:

Answer:

Given: Population of ducks in lake, last year is 60.

Also, the population of ducks this year decreased by 1/4 th over the last year.

So, the population of ducks this year is = 60*(1-1/4)

                                                          = 60*(3/4)

                                                          = 45

Therefore, the population of ducks this year is 45 ducks.

The slope of the line through C(2, 5) and D(4,7) will be 1.

A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The slope of the line is given as,

m = (y₂ - y₁) / (x₂ - x₁)

Then the slope of the line through C(2, 5) and D(4,7) will be given as,

m = (y₂ - y₁) / (x₂ - x₁)

m = (7 - 5) / (4 - 2)

m = 2 / 2

m = 1

Thus, the slope of the line through C(2, 5) and D(4,7) will be 1.

Answer:

The answer is adding 7 to both sides.

Step-by-step explanation:

5x-7=18

  +7  +7

5x= 25

x=5

Answer:

Answer: Adding 7 to both sides.

Step-by-step explanation:

You always do the "inverse" of the number without the variable next to it and either "add" or "subtract" it to the other side.

Ex: 7x - 3 = 18

In this case, you would add the 3 to the other side.

7x - 3 = 18

    + 3    +3

7x = 21

7x    7x

Step one:

given data

Garden soil costs $5.00 per a 2 cubic foot bag

dimension of rectangular garden raised

8 feet by 4 feet , depth is 6 in

6 in to feet= 0.5ft

the volume of the soil in the  garden is

volume= 8*4*0.5= 16ft^3

Step two:

now if 2ft^3 cost $5

         16ft^3 will cost x

cross multiply

x*2=16*5

divide  both sides by 2

x= 16*5/2

x=80/2

x=$40

Answer: C. Mount Everest is about 23 times as tall as the Empire State Building

Step-by-step explanation:

The options are:

A.There is no way to compare these heights

B.Mount Everest is about 40 times as tall as the Empire State Building

C.Mount Everest is about 23 times as tall as the Empire State Building

D.The Empire State Building is about 23 times as tall as Mount Everest

Mount Everest = 8.8×10^3 meters = 8800 meters

Empire State Building = 3.8×10^2 = 380 meters

Mount Everest is (8800 / 23) = 33 times as tall as the Empire State Building. Therefore, the correct option is C.

The volume of a sphere with 6 inch radius is 36(pi) cubic inches or approximately 113 cubic inches.

Step-by-step explanation:

hope it helps, please mark as brainliest

The volume of the given sphere is 113.04in³

The volume of a sphere of radius R is given by the formula:

V = (4/3)*3.14*R³

Here we know that the diameter is 6 inches, and the radius is half of that, then the radius is:

R = 6in/2 = 3in

Replacing that in the formula we will get:

V = (4/3)*3.14(3in)³

V = 113.04in³

Using the concept of division we can find the number of times Elisa and Frances withdraw the money.

Division is one of  fundamental mathematical operations, which breaks a bigger number into smaller groups with the same number of components.

The amount withdrawn by Elisa at a time =$27 The amount withdrawn by Elisa in total =$216

The  number of times Elisa withdrew

=[tex]\frac{total amount withdrawn}{amount withdrawn per time}[/tex]

=[tex]\frac{216}{27}[/tex]

=8

The amount withdrawn by Frances each time=$46

The amount withdrawn by Frances in total=$184

The number of times Frances withdrew

=[tex]\frac{total amount withdrawn}{amount withdrawn per time}[/tex]

=[tex]\frac{184}{46}[/tex]

=4

The number of times Elisa withdrew is 8 while the number of times Frances withdrew is 4.This implies Elisa has made withdrawals than Frances.
