I need help to these questions. Convert these fractions to a decimal 7/8 , 4 3/8. Thanks
ehidna [41]
Simple...

you have: \frac{7}{8} and 4 \frac{3}{8}

Now, the first one is easy just divide it...

\frac{7}{8} =0.875

Now....

4 \frac{3}{8}    needs to be converted...

Multiply the whole number*denominator...

4*8=32

Now add the numerator....

32+3=35

Now use the original denominator...

\frac{35}{8}

Now divide...

\frac{35}{8}=4.375


Thus, your answer.

(02.05 MC) A dance school has 63 ballet dancers. If 42% of the total number of dancers in the school are ballet dancers, what is
Elena L [17]

Alright, lets get started.

Suppose total number of dancers in school = x

We have given in question, 42 % of total dancers are ballet dancers.

So, we could find number of ballet dancers by finding 42 % of total dancers.

Number of ballet dancers = x * 42 %

Number of ballet dancers = x * 42/100 = 0.42 x

As per given in question, there are 63 ballet dancers in school.

Which means 0.42 x = 63

Dividing 0.42 from both sides

0.42 x / 0.42 = 63 / 0.42

x = 150

Hence number of total dancers in school = 150 : Answer

Hope it will help :)

I need help with this question. I would like a detailed explanation please!(what are the measurements)​
garri49 [273]

Answer:

X = 66

Step-by-step explanation:

A straight line is equal to 180 degrees so if you have one side of that line you can figure out the inside angle.

Now that you have two of the angles inside the triangle add them up. All the interior angles of a triangle will add to 180. So add up 38 and 76 to get 114. Now do 180 - 114, you should get 66

so x = 66

Given that xy=3/2 and both x and y are nonnegative real numbers, find the minimum value of 10x (3y/5)
Stells [14]

The munimum value is, at x = 3/10, y = 5 and 10x+3y/5 = 6.

<h3>What are nonnegative real numbers?</h3>
  • Non-negative real numbers are the set of positive real numbers that are bigger than 0 (zero).
  • That is, the true values are either positive or negative.
  • The collection will include numbers such as 0, 1, 2, 3, 4, 5, and so on.

To find the minimum value of 10x (3y/5):

Given - y = 3/(2x)

So, we want the bare minimum of,

  • = 10x + 3/5 × 3/(2x)
  • = 10x + 9/(10x)

Take the derivative to obtain:

  • = 10 - 9/(10x^2)

When you set it to zero, you get:

  • = 100x^2 - 9 = 0
  • = (10x-3)(10x+3) = 0
  • = x = ± 3/10

So, at x = 3/10, y = 5 and 10x + 3y/5 = 3 + 3 = 6.

Therefore, the munimum value is, at x = 3/10, y = 5 and 10x+3y/5 = 6.
