What is sector of circle?

A circle's sector is a pie-shaped portion made up of the arc and its two radii. At both ends of the arc, when a section of the circle's circumference (also called as an arc) and two of its radii meet, a sector is produced. A sector of such a circle resembles a piece of pizza or a pie in shape.

A circle ranks among the most ideal shapes in geometry. The simplest geometric shape is that of a circle's sector. It has a number of its own components. such as sector, segmentation, circumference, segment, and diameter. The area of the sector is 250 units².

The difference of the two numbers is 1.Their sum is 23.find the numbers

Answers

Answer:

11 and 12

Step-by-step explanation:

The two numbers will be called x and y. The sum of x and y is 23 and the difference is 1.

x + y = 23  

x - y = 1

Add the equations together

x + y + x - y = 23 + 1

2x = 24

x = 12

y = x - 1

y = 11

Mrs. Roberts sewed m shirts using 2 yards of cloth for each shirt. She also sewed (m+2) dresses, using 5 yards of cloth for each dress. A) How much cloth did she use altogether? Give your answer in terms of m. B) If m= 7, find how much more cloth she used to sew the dresses than the shirts.

Answers

Answer:

7m + 10

31 yards

Step-by-step explanation:

Shirts :

Number of shirts sewed = m

Yards of cloth used per shirt = 2 yards

Number of dresses sewed = m + 2

Yards of cloth used per dress = 5 yards

Cloth used altogether :

Cloths used for shirt = 2 * m = 2m

Cloth used for dress = 5 * (m+2) = 5m + 10

2m + (5m + 10) = 7m + 10

If m = 7

Cloth used for dress - Cloth used for shirt

(5(7) + 10) - (2(7))

(35+10) - 14

45 - 14 = 31 yards

If you know that cosine of the obtuse supplementary angle -0.3456 what can you determine about the acute angle

Answers

Answer:

69.8°

Step-by-step explanation:

Since cosФ = -0.3456

Ф = cos⁻¹(-0.3456)

Ф = 110.2°

Since the angles are supplementary, let the acute angle be x

So, x + 110.2° = 180°

x = 180° - 110.2°

x = 69.8°

What are equivalent expressions?

Equivalent expressions are similar expressions that when being solved provide the same solution. Equivalent expressions are used widely in the expansion of algebraic equations.

From the given information, we have:

=  m(n + p)

To determine the equivalent expression for the above algebraic equation, we need to expand the bracket as follows:

375 fish are swimming in a school. First, 47 fish swim away. Then 116 more fish join the school. How many fish are in the school now

Answers

Answer:

The answer is 444.

Step-by-step explanation:

First, you do 375 - 47 because 47 swam away, decreasing the amount of fish that are swimming in a school. Then, 116 fish come back to swim so you add 116 to get 444.

There are 444 fish in the school now.

What is Unitary Method?

The unitary method's formula is to identify the value of a single unit, then multiply that value by the number of units to obtain the required value.

The unitary approach is used when we have several goods with varying values in our possession. To get the value of one unit, we simply divide the total value by the number of units.

We have,

375 fish are swimming in a school.

First, 47 fish swim away.

Then 116 more fish join the school.

So, the number of fish in the school now

= 375 - 47 + 116

= 444 fish

Thus, there are 444 fish in school now.
