Answer:

52% are girls

Step-by-step explanation:

We know that there are 650 sixth-graders and 338 of them are girls, we are then asked to find the percentage of how many are girls.

We have the fraction 338 over 650 but need to reduce it.

To solve this, we need to find the GCF of 650 and 338, which is 26, so divide both the numerator and denominator by 26.

\frac{338/26}{650/26}

\frac{13}{25}

Now divide the 13 and 25 :

13 / 25 = 0.52

0.52 * 100 = 52%

Therefore, 52% of the sixth-graders in the school are girls

Answer: 52%

Step-by-step explanation:

338/650 and x/100 since we are trying to find a persentage, we have to make an proportion

338x100=33800 because we cross multiply

33800/650=52 because 33800 is now over 650

And 52 as a persentage is 52% which is how we get to our answer of 52%

I hope this helps

Hopefully it's brainliest

The heights of a students(in cm) are:54,52,56,54,58,51.<br><br> Find the median.​
kumpel [21]

Answer:

To answer this question you will use the median height of 156 centimeters and the fact that there are 26 kids in the class to know that the median is not in the data set, therefore it breaks the data into two equal halves with 13 in each half.

There would be 13 less or equal to the median height.

hope i helped ;)

Jason has 4 gallons of hand sanitizer that contains 25% alcohol. He wants to make a hand sanitizer that contains 50% alcohol. Ho
alexandr402 [8]

Answer:

2 gallons of pure alcohol

Step-by-step explanation:

Let x represent the number of gallons of pure alcohol needed, and create an equation:

4(0.25) + x(1) = (x + 4)0.5

1 + x = 0.5x + 2

x = 0.5x + 1

0.5x = 1

x = 2

So, 2 gallons of pure alcohol should be added.

How many solutions does the equation have?<br><br> 2x + 3 = 4x + 2
fenix001 [56]
Well, solve for x.

Combine like terms by performing the opposite operation of subtracting 4x on both sides of the equation

The 4x's will cross out on the right

4x - 4x = 0x = 0

On the left:

2x - 4x = -2x

Now the equation looks like:

-2x + 3 = 2

Continue to combine like terms by subtracting 3 on both sides of the equation

On the left:

3 - 3 = 0

On the right:

2 - 3 = -1

Equation:

-2x = -1

Isolate x by performing the opposite operation of dividing -2 on both sides of the equation

On the left:

-2x ÷ -2 = 1

On the right:

-1 ÷ -2 = 1/2

x= 1/2

So, there is only one solution: 1/2
