A fruit stand sells apples, peaches and tomatoes. Today, they sold 4 apples for every 5 peaches. They sold 2 peaches for every 3
Brrunno [24]

Answer:

He sold 32 apples, 40 peaches and 60 apples.

Step-by-step explanation:

We are given that

4 apples are sold every 5 peaches and

3 tomatoes are sold every 2 peaches.

i.e. the ratio is apples: peaches = 4 : 5     ...... (1)

and the ratio peaches: tomatoes = 2 : 3   ...... (2)

Peaches are the common link here in both the ratio terms.

Let us make the peaches value in both the <em>ratio as 10 </em>to make it equal in both the ratio terms.

Multiply (1) by 2 and (2) by 5:

The ratio becomes;

apples:peaches = 8:10

peaches: tomatoes = 10:15

In other words, the ratio becomes:

apples:peaches:tomatoes = 8:10:15

Let the number of apples = 8x

Let the number of peaches = 10x\\

Let the number of tomatoes = 15x

We are given that total fruits are = 132

\Rightarrow 8x+10x+15x = 132\\\Rightarrow 33x = 132\\\Rightarrow x =4\\

So, number of apples sold = 8 \times 4 = 32

Number of peaches sold = 10 \times 4 = 40

Number of tomatoes sold = 15 \times 4 = 60

4x- [ x +2 ] + 6 = 2 [ 3x +8 ]
slava [35]

Answer:

x=-4

Step-by-step explanation:

4x-(x+2)+6=2(3x+8)

4x-x-2+6=6x+16

3x+4=6x+16

4=6x-3x+16

4=3x+16

3x=4-16

3x=-12

x=-12/3

x=-4

Harlp needed ok thanks dudes
Ivanshal [37]

Solution:

<u>A few definitions...</u>

  • Rational number - Any integer, fraction, terminating decimal, or repeating decimal is classified as a rational number
  • Irrational number - All the real numbers which are not rational numbers.

<u>Option A - Rational or Irrational?</u>

  • 1/2 + 1/3

Since both are known as fractions, they are rational numbers.

<u>Option B - Rational or Irrational?</u>

  • √2 + 5/2

√2 is classified as an Irrational number because if it is simplified, it does not result in any integer, fraction, terminating decimal, or repeating decimal.

<u>Option C - Rational or Irrational?</u>

  • 1/√4 + 7/2
  • => 1/2 + 7/2
  • => 8/2 = 4

Since this is an integer, this is rational.

<u>Option D - Rational or Irrational?</u>

  • √9 + √4
  • => √3 x 3 + √2 x 2
  • => 3 + 2 = 5

Since this is an integer, this is rational.

In conclusion...

Option B is correct.

20 points for this one:))
baherus [9]

Answer:

  • C. 4/5

Step-by-step explanation:

  • cos  = adjacent / hypotenuse
  • cos (M) = MN / ML = \sqrt{ML^2 -NL^2 }/ML = \sqrt{25^2-15^2}/25 = 20/25 = 4/5

Correct choice is C
