Answer:

  see below

Step-by-step explanation:

The basic formula for this chart is ...

  Percentage = Base × Rate

Dividing by Base or Rate gives two other versions of the same relation:

  Rate = Percentage/Base

  Base = Percentage/Rate

These are summarized in the chart at the second attachment. Covering one of the cells in the chart tells you how that cell is computed. (See the formulas above.)

___

It is convenient to let a spreadsheet do the math. Unfortunately, for this problem there are three different formulas that need to be entered and copied to non-adjacent cells. Even so, IMO, it beats punching numbers on a calculator.

The figure below shows concentric circles, both centered at 0.0
Rama09 [41]

Answer:

  C.  18 cm

Step-by-step explanation:

The ratio of the sides of the triangle shown is 12 : 15 = 4 : 5. We know it is a right triangle, so we know the missing side length completes the ratio

  3 : 4 : 5 = 9 : 12 : 15

Half of XY is 9 cm, so the length of the entire chord is 18 cm.

_____

The chord is tangent to the inner circle, so makes a 90° angle with the radius to that tangent point. This tells you that the triangle shown is a right triangle. It also tells you that the short radius bisects the chord. The Pythagorean theorem can be used to find the length of the side not shown (half the chord length).

The unknown side (a) can be found from  ...

  15² = 12² +a²

  225 -144 = a² . . . . . . subtract 12²

  81 = a² . . . . . . . . . . .  simplify

  9 = a . . . . . . . . . . . . . take the square root

The chord length is 2a, so is ...

  2(9 cm) = 18 cm . . . . length of chord XY

velikii [3]
It should be x < -10 because when you divide by a negative number the inequality sign flips.

In Amy’s backyard, there are also chickens and rabbits. There are 5 more chickens than rabbits. The total number of legs is 130.
Butoxors [25]

Answer:

There are 25 chickens and 20 rabbits

Step-by-step explanation:

Let

x-----> the number of chickens

y ----> the number of rabbits

Remember that

1 chicken has two legs

1 rabbit has four legs

so

2x+4y=130 -------> equation A

x=y+5 -----> equation B

Substitute equation B in equation A and solve for y

2(y+5)+4y=130

2y+10+4y=130

6y=120

y=20 rabbits

Find the value of x

x=y+5

x=20+5=25 chickens

5. Find the measure of the indicated angle.
Angelina_Jolie [31]

Answer:

180 - 26 = 154

10x + 8 + 9x - 25 = 154

19x - 17 = 154

19x = 171

x= 9

so » C is:98°

and » D is: 56°
