Find the approximate radius of a circle with a circumference of 198 centimeters. Use 3.14
for it Round to the nearest hundredth.

A. 63.06
B. 31.53
C. 621.72
D. 310.86

Answers

Answer 1

The radius of the circle is around 31.65 cm. Choice B

The formula C = 2πr , where C is the circle's circumference and r is its radius, yields the circumference of a circle. In this illustration, the circle's circumference is given as 198 cm

C = 2πr

The formula to calculate the radius can be revised as follows:

r = C / (2π)

r = 198 / (2 * 3.14)

To perform the calculation, divide the numbers:

r ≈ 198 / 6.28

r ≈ 31.65

The circle's estimated radius is 31.65 centimetres as a result.

So, rounded to the closest hundredth, the estimated radius of the circle with a circumference of 198 centimetres is 31.65 centimetres.

The closest option to 31.65 in the list of possible answers is B. 31.53. It's crucial to keep in mind that choosing 3.14 as an approximation for involves some mistake and that the precise radius number might change slightly.

When rounded to the next hundredth, the radius is 31.65. This result can be compared to the other solutions to show that:

B. 31.53.

Answer:

x = 15 ft

Step-by-step explanation:

Triangle ACD is similar to triangle ABE based on the information given, therefore we can set up a proportion to compare the sides:

side AE / side EB = side AD / side DC

4/6 = 10/x

Solve for x

x = (10)(6) / 4

x = 60 / 4

Suppose that appoximately 261,000,000 people live in the united states. Of these people 37,600,000 speak a language other than english at home who speak another lanague at home over 45 percent speak spanish

Answers

Answer:

16,920,000 people speak Spanish at home in the United States, which represents 6.48% of the country's population.

Step-by-step explanation:

Given that approximately 261,000,000 people live in the United States, and of these people 37,600,000 speak a language other than English at home, of which over 45 percent speak Spanish, to determine the number of people who speak Spanish in the United States, the following calculation has to be done:

37,600,000 x 0.45 = X

16,920,000 = X

261,000,000 = 100

16,920,000 = X

16,920,000 x 100 / 261,000,000 = X

6.48 = X

Thus, some 16,920,000 people speak Spanish at home in the United States, which represents 6.48% of the country's population.

Answer:

  (x -2)² +(y -4)² = 25

Step-by-step explanation:

The area of a square is half the product of the diagonals, so that product is 50·2 = 100. This is the square of the diameter, so the square of the radius is 100/4 = 25. Then the circle equation is ...

  (x -h)² +(y -k)² = r² . . . . . . . circle with center (h, k) and radius r

A. z= 5.5
B. z = 3.5
D. z = -2.5
E. z = -0.5

Answers

Answer:

The answer is z = 7.

Step-by-step explanation:

1) Divide both sides by 25.

[tex]z - 2 = \frac{125}{25} [/tex]

2) Simplify 125/25 to 5.

[tex]z - 2 = 5[/tex]

3) Add 2 to both sides.

[tex]z = 5 + 2[/tex]

4) Simplify 5 + 2 to 7.

[tex]z = 7[/tex]

Thus, the answer is z = 7.

A shape is made of 9 right triangles of equal size and three identical rectangles.
Each rectangle measures 7 mm wide by 3 mm high. The rectangles are each
7 mm wide by 3 mm high. What is the total area, in square millimeters,
of the shape?

Answers

Answer:

The area of the figure is 157.5 square millimeters.

Step-by-step explanation:

Since a shape is made of 9 right triangles of equal size and three identical rectangles, and each rectangle measures 7 mm wide by 3 mm high, while the rectangles are each 7 mm wide by 3 mm high, to determine what is the total area, in square millimeters, of the shape, the following calculations must be performed:

Area of a rectangle: base x height

Area of a triangle: (base x height) / 2

7x3 = 21 = Rectangle area

7x3 / 2 = 10.5 = Triangle area

21 x 3 + 10.5 x 9 = 157.5

Thus, the area of the figure is 157.5 square millimeters.

Answer:

$40000

Step-by-step explanation:

Offer :

For every $120 spent ; $3 is donated

In other to raise $1000 ; $x would have to be spent ; we can obtain the value of x using cross multiplication ;

$120 = $3

$x = $1000

Cross multiply

$(120 * 1000) = $3 * x

$120000 = $3x

x = 120000 / 3

x = 40,000

Hence, in other to raise $1000 ; $40000 would have to be spent by customers.

George has only Quarters and nickels in his piggy bank.He has a total of 90 coins.The value of the coins is $16.10. Write and solve a system that can be used to determined how many quarters and how many nickels he has.

Answers

Answer:

The number of

Quarters = q = 58 quarters

Nickels = n = 32 nickels

Step-by-step explanation:

It is important to note that:

A quarter is worth 25 cents = 0.25q

A nickel is worth 5 cents = 0.05n

George has only Quarters and nickels in his piggy bank.

Let the number of

Quarters = q

Nickels = n

He has a total of 90 coins.

Hence,

q + n = 90.... Equation 1

q = 90 - n

The value of the coins is $16.10.

Hence,

0.25q + 0.05n = 16.10....Equation 2

We substitute 90 - n for q in Equation 2

0.25(90 - n) + 0.05n = 16.10

22.5 - 0.25n + 0.05n = 16.10

Collect like terms

- 0.25n + 0.05n = 16.10 - 22.5

-0.2n = - 6.4

n = -6.4/-0.2

n = 32 nickels

Solving for q

q = 90 - n

q = 90 - 32

q = 58 quarters

Therefore, the number of

Quarters = q = 58 quarters

Nickels = n = 32 nickels

Find h. 11 in. h = [?] in. 1 1 1 14 in. Enter​

Answer:

You know that the Pythagorean Theorem is:

a²+b²=c²

,

Where:

a

is the length of one of the legs,

b

is the length of the other leg, and

c

is the length of the hypotenuse.

You know the lengths of the two legs are

7 and 11

, so we'll say that

a is 7 , and b is 11

Knowing that, we can plug those into our equation and simplify like so:

7²+11²=c²
