Answer:

55\frac{5}{9} %

Step-by-step explanation:

First we find the number of boys that have been members for more than two years:

B = 80% of 35 = 0.8 * 35 = 28 boys

Then, we find the number of girls that have been members for more than two years:

G = 25% of 28 = 0.25 * 28 = 7 girls

So, the total number of people that have been members for more than two years is:

T = B + G = 28 + 7 = 35

The total number of people in the club is:

Total = 35 + 28 = 63 people

So the percentage of people that have been members for more than two years is:

P = (T/Total)*100% = 3500/63 % = 55\frac{35}{63} % = 55\frac{5}{9} %

Answer:

55%

Step-by-step explanation:

What we must do is get the total number of people, that is, boys and girls who have been a member for more than 2 years, that is:

children: 0.8 * 35 = 28

girls = 0.25 * 28 = 7

Now, passing knowing the%, would be dividing the sum of the above by the sum of the total club members:

(28 +7) / (35 + 28) = 0.55

Since it is a number below 1, it cannot be a mixed number.

Problem PageQuestion A Web music store offers two versions of a popular song. The size of the standard version is 2.6 megabytes
dalvyx [7]

Answer:

There were 210 downloads of the standard version.

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

x is the number of downloads of the standard version.

y is the number of downloads of the high-quality version.

The size of the standard version is 2.6 megabytes (MB). The size of the high-quality version is 4.2 MB. The total size downloaded for the two versions was 4074 MB.

This means that:

2.6x + 4.2y = 4074

Yesterday, the high-quality version was downloaded four times as often as the standard version.

This means that y = 4x

How many downloads of the standard version were there?

This is x.

2.6x + 4.2y = 4074

Since y = 4x

2.6x + 4.2*4x = 4074

19.4x = 4074

x = \frac{4074}{19.4}

x = 210

There were 210 downloads of the standard version.

The value of the 7 in 27,459 is how many times the value of the 7 in 40,735?
alukav5142 [94]

Answer:

10

Step-by-step explanation:

The 7 in 27,459 is in the <em>thousands</em> place.

The 7 in 40,735 is in the <em>hundreds</em> place.

Any digit in the thousands place has 10 times the value of the same digit in the hundreds place. (The multiplier is 1000, instead of 100.)

_____

In the base-10 number system, each digit location has 10 times the value of the location to its right. The value is determined by the place the digit occupies in the number. That is why it is called a place-value number system.
