You are researching the price of MP3 players. You found an average price of $58.80. One MP3 player costs $56 and another costs $

Butoxors [25]

The price of third MP3 player is $58.40

Step-by-step explanation:

Given,

Cost of one MP3 palyer = $56

Cost of another MP3 player = $62

Average price of MP3 player = $58.80

Let,

Cost of third MP3 player = x

Average = $\frac{Sum\ of\ costs}{Number\ of\ items}$

${58.80}=\frac{56+62+x}{3}$

Multiplying both sides by 3

$3*{58.80}=\frac{56+62+x}{3}*3\\176.40=118+x\\176.40-118=x\\58.40=x\\x=58.40$

The price of third MP3 player is $58.40

One number to the right of the decimal will mean there are two numbers to the left of the decimal.

When rounding to 50 as the nearest ten the number needs to be between 45 and 54.

Using the 3 numbers shown that would be 48.3

The ratio of the number of dogs to the number of cats is 4:5. There are 270 animals on the rescue farm. for each of the followin

romanna [79]

Answer:

see the procedure

Step-by-step explanation:

Let

x ----> the number of dogs

y ---> the number of cats

we know that

The ratio of the number of dogs to the number of cats is 4:5

$\frac{x}{y}=\frac{4}{5}$

$x=\frac{4}{5}y$ ----> equation A

That means ---> The number of dogs is 4/5 the number of cats

There are 270 animals on the rescue farm

$x+y=270$ ----> equation B

Substitute equation A in equation B

$\frac{4}{5}y+y=270$

solve for y

$\frac{9}{5}y=270$

$y=270(5)/9\\y=150\ cats$

Find the value of x

$x=\frac{4}{5}(150)=120\ dogs$

<u><em>Verify each statement</em></u>

a) The number of dogs is 4/5 the number of cats

The statement is true (see the explanation)

b) 4/5 of the pets at the farm are dogs

The statement is false

Because

(4/5)(270)=216 dogs

The number of dogs is 120 not 216 (see the explanation)

c) There are exactly 30 more cats than dogs

The statement is true

Because, there are 150 cats and 120 dogs (see the explanation)

d) There are exactly 30 dogs at the farm

The statement is false

Because, there are 120 dogs in the farm (see the explanation)

e) 5/9 of the pets at the farm are cats

The statement is true

Because

(5/9)270=150 cats

The number of cats is 150 (see the explanation)

A circular mirror measures 24 cm in diameter.

Basile [38]

Answer:

The perimeter or circumference of a half mirror = 37.68 cm

Step-by-step explanation:

The diameter of circular measure = 24 cm

We know that the perimeter of a circular shape is called the 'circumference', with the formula

Circumference of a circle = C = 2πr

When the mirror is cut into half, the diameter gets half as well.

Thus, the diameter of a half mirror = 24/2 = 12 cm

We know that radius = r = diameter / 2 = 12/2 = 6 cm

Thus, the perimeter of half of the mirror = C = 2πr

= 2(3.14)6

= 37.68 cm

Therefore, the perimeter or circumference of a half mirror = 37.68 cm

Gray started the week with $150 in his checking account. The chart shows the credits and charges to his account during the week.

BlackZzzverrR [31]

Answer:

111

Step-by-step explanation:

150 + 20 = 170

170 - 52 = 118

118 + 23 = 141

141 - 16 = 125

125 + 14 = 139

139 - 28 = 111
