Answer:

725.71 cm

Step-by-step explanation:

Using the attached diagram :

Diameter of inner circle = 26

Radius of inner circle = 26/2 = 13

Radius of entire circle = 13 + 7 = 20

The Area of a circle = πr²

Area of inner circle = π13² = 169π

Area of entire circle = π20² = 400π

Area of shaded portion :

Area of entire circle - Area of inner circle

400π - 169π = 231π = 725.71 cm

Answer:

[tex] \frac{12}{x} = \frac{20}{25} \\ 20x = 25 \times 12 \\ x = 15[/tex]

Hello! answer: 15

25 ÷ 20 = 1.25

1.25 × 12 = 15 so 15 is the answer Hope that helps!

Answer:

A = 25π cm²

In decomal form = 78.5cm²

Step-by-step explanation:

Area of a circle is expressed as;

A = πr²

r is the radius of the circle

Since we are not given the radius. Let us assume that r = 5cm

Substitute into the formula;

A = π(5)²

A = 25π cm²

As a decomal;

A = π(5)²

A = 3.14 * 25

A = 78.5cm²

Note that the radius of the circle was assumed. The same calculation can be employed for any value of the radius

Answer:

Approximate volume of ice cream = 3.03 inches

Step-by-step explanation:

Given - An empty ice cream cone has a height of 3.02 inches and a radius

of 0.98 inches.

To find - What is the approximate volume of ice cream it will  hold within the cone  ?

Proof -

We know that,

Volume of the cone = [tex]\frac{1}{3}\pi r^{2}h[/tex]

where

r is the radius of the cone

h is the height of the cone

Here,

Given that,

r = 0.98 inches

h = 3.02 inches

So,

Volume = [tex]\frac{1}{3}\pi r^{2}h[/tex]

             = [tex]\frac{1}{3}(3.14) (0.98)^{2}(3.02)[/tex]         ( Consider the value of [tex]\pi[/tex] = 3.14)

             = 3.0373

∴ we get

Approximate volume of ice cream = 3.03 inches

So,

The correct option is - G. 3 in 3

Answer:

9 for the hypotenuse, [tex]\sqrt{64}[/tex] and [tex]\sqrt{25}[/tex] for the two legs

Step-by-step explanation:

For these types of problems, we need to make sure that the values of legs are as big as possible while keeping the hypotenuse larger than legs because otherwise, it won’t be a right triangle.  

So for the hypotenuse, we have to put the largest number in this number bank because the hypotenuse has to be larger than both legs. So the hypotenuse will equal 9. The rest is simple. Get the numbers as large as possible. Since the hypotenuse must be larger than both legs, we cannot use sqrt(81) and sqrt(64) (that would’ve been sweet). So we have to use sqrt(64) and sqrt(25) because sqrt(49) and sqrt(36) are already taken since we can only use a number once.

I'm not an expert at this and I cannot guarentee that this is correct. But I hope that this helps.

Answer:

8 - x

Step-by-step explanation:

2745

Step-by-step explanation:

solve it like simultaneously

180x+120y greater than 5145

180x+120y greater than 2400

eliminate x

y will now be greater than 2745

Answer:

1) P(First card was a king) =  1/13 2.) 1/4

Step-by-step explanation:

1) P(First card was a king) = n(King)/n(Total) = 4/52 = 1/13

2. P(Heart)13/52 = 1/4

Answer:

1/52

Step by step explanation:

First, find the probability that the first card will be a King. Since there are 4 possible kings, and 52 cards, the probability is 4/52.

Then, find the probability that the second card will be a heart. "given that the first card is replaced" means that there are 13 possible hearts regardless of the suit of the first card. So 13/52 is the probability.

To find the probability of both occurrences, multiply them.

4/52 * 13/52 = 52/2704

52/2704 can be simplified to 1/52. So that is the probability that the first card will be a king and the second card will be a heart.

Answer:

If the marginal revenue exceeds the marginal cost, then the firm can increase profit by producing one more unit of output. For example, at an output of 4 in Figure 3, marginal revenue is 600 and marginal cost is 250, so producing this unit will clearly add to overall profits.

The following figures are parallelograms:

Figure A

Figure B

Figure E

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

Explanation:

If the diagonals of the quadrilateral are the same length (aka congruent), then we can prove that we have the opposite sides parallel. That would conclude in the figure being a parallelogram. Therefore, choice A is a parallelogram because of this fact. Choice C is not a parallelogram because of this.

Also, recall that parallelograms have their opposite sides being the same length. Think of a rectangle, but we can slant the sides as figure B shows. Figure B is a parallelogram due to the opposite sides being the same length. More specifically, it's a rhombus (because all four sides are the same). Any rhombus is a parallelogram, but not the other way around.

One last useful property we'll use is the fact that adjacent angles of a parallelogram are supplementary. This means the angles add to 180. In figure D, the adjacent angles add to 74+105 = 179, which isn't 180. So we rule out choice D. Choice E works though because 55+125 = 180.

Answer:

The area of the shape is 18cm^2

Step-by-step explanation:

Answer:

18 meters

Step-by-step explanation:

The circumference is given by

C = pi *d

18 pi = pi *d

Divide each side by pi

18 pi / pi = pi * d/pi

18 =d

Answer:

18 m

Step-by-step explanation:

C = π · d

18π = π · d

18 = d

Answer: which question

Step-by-step explanation:

Answer:

9 years

Step-by-step explanation:

Given data

Principal= $10000

Rate= 3%

Final amount= $12700

The simple interest expression is given as

A=P(1+rt)

substitute

12700=10000(1+0.03*t)

12700=10000+300t

collect like terms

12700-10000= 300t

2700=300t

divide both sides by 300

t= 2700/300

t= 9 years

Answer:

75

Step-by-step explanation:

Angles in a triangle add up to equal 180

That being said we can find the missing angle by subtracting the measures of the given angles from 180

Thus missing angle = 180 - 34 - 71

180 - 34 - 71 = 75

Which means that the missing angle = 75

Answer:

? = 180 - (angle 1 + angle 2)

? = 180 - (71 + 34)

? = 180 - 105

? = 75°

=> To check is the answer is right, add all 3 angles together and their sum should be 180°

Hope this helps!

Answer:

1) 12 (option b)

2) 41, 9, 40 (option a)

Step-by-step explanation:

Pythagorean Theorem: a² + b² = c²

1) Let the unknown leg be x cm long. Thus,

5² + x² = 13²

Simplify and solve.

25 + x² = 169

x² = 144

x = 12

2) Apply the Pythagorean Theorem.

9² + 40² = 41² = 81 + 1600 = 1681

1681 = 1681

a is true.

Just in case, let's check the other options.

5² + 8² = 9² = 25 + 64 = 81

89 = 81, false

b is false

10² + 11² = 12² = 100 + 121 = 144

221 = 144, false

c is false

3² + 4² = 6² = 9 + 16 = 36

25 = 36, false

d is false

Thus, a is the answer.

Hello! answer: 80

Step-by-step explanation:

What I did was find area of the shape all together without the cut out square and that was 96 because 12 × 8 = 96 then I found the area of the square 4 × 4 = 16 so I just subtract that by 96 and then thats are answer so...

96 - 16 = 80 so 80 is our area HOPE THAT HELPS!

Answer:
