Both circles have the same center. What is the area of the shaded region? r=10 m 7 m Use 3.14 for ​. Write your answer as a whole number or a decimal rounded to the nearest hundredth. square meters

Answers

Answer 1

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

The area of a triangle is 55x^3+15x^2-25. The length of the triangle is 5x. What is the width?

Answers

Answer:

The area of a triangle =55x^3+15x^2-25

1/2×length×width=55x^3+15x^2-25

5x/2×width=55x^3+15x^2-25

width=[55x^3+15x^2-25]×2/5x

width=22x²+6x-10/x is your answer

The mean of six numbers is 10. When
mother number is added the new mean is
9. Find the number added.​

Answers

Answer:

3

Step-by-step explanation:

If 6 numbers have a mean value of 10, it means that the sum of the numbers divided 6 is equal to 10. This can be expressed as:

x÷6=10

x=60

The new number added will be the 7th number and now the mean is 9. You have to ask what number divided by 7 is equal to 9? This can be expressed as:

y÷7=9

y=63

63-60=3

So the new number added is 3

Answer:

3

Step-by-step explanation:

Mean is calculated as

mean = [tex]\frac{sum}{count}[/tex]

Given the mean of 6 numbers is 10, then

[tex]\frac{sum}{6}[/tex] = 10 ( multiply both sides by 6 )

sum = 60

When another number x is added then count is 7

[tex]\frac{60+x}{7}[/tex] = 9 ( multiply both sides by 7 )

60 + x = 63 ( subtract 60 from both sides )

x = 3 ← the number added

What is the angle relationship between c and d?
Also what is the relationship between c and f?
(could be Vertical, alternate exterior, alternate interior, corresponding, same-side interior, same-side exterior, or linear pair.)

Answers

Answer:

1. linear pair (c and d)

2. alternate interior angles (c and f)

Step-by-step explanation:

Here, we want to get the relationship between angles

From what we have , we can see that angle d and angle c lie on a straight line

Thus, we have that angle c and angle d are supplementary angles since they will add up to give 180 degrees . So we can call the two a linear pair

For c and f, we can notice a z-like angle between the two

In this case, when we have a z-like angle, the relationship that exists between the two angles is that they are alternate interior angles

Answers

Answer:

x = 145°

Step-by-step explanation:

We know that y = 98°, so we can find ∠DBC:

180°-y = ∠DBC

180°-98° = 82°

We also know that z = 63°, therefore we can apply exterior angle of triangles to find x.

∠DBC + z = x

82°+63° = x

x = 145°
