Last year 7/16 of all students at a school participated in the science fair. About what percentage of the students participated?

Answers

Answer:

43.75% students were participated last year.

Step-by-step explanation:

We have been given that last year 7/16 of all students at a school participated in the science fair.

Let us suppose the total number of students were x. Then, number of students participated last year is given by

$(7)/(16) x$

Hence, the percentage of the students participated last year is given by

$\%=((7)/(16)x )/(x) * 100\n\n\%=(7)/(16)* 100\n\n\%=43.75\%$

Therefore, 43.75% students were participated last year.

7/16*100=43.75% Can be rounded to 44

If Sergio ate 12 packages of banana chips in a week, which equation can be used to find the fraction of packages of banana chips B he ate every day and what is the fraction?

Answers

If you would like to find the fraction of packages of banana chips Sergio ate every day, you can calculate this using the following steps:

12 packages of banana chips ... 1 week = 7 days
x packages of banana chips = ? ... 1 day

12 * 1 = 7 * x
12 = 7 * x
x = 12 / 7
x = 1 5/7 packages of banana chips per day

The fraction would be 12/7 packages of banana chips per day.

What is 2,200 yards in miles? Round to the nearest tenth of a mile.

Answers

There are 1.3 miles in 2,200 yards.

What is unit conversion?

It is the conversion of one unit to another unit with its standard conversion.

Examples:

1 hour = 60 minutes

1 minute = 60 seconds

1 km = 1000 m

We have,

2,200 yards ____(1)

1 mile = 1760 yards _____(2)

Now,

From (1) and (2),

1 mile = 1760 yards

Multiply 2,200/1760 on both sides.

2,200/1760 x 1 mile = 2,200/1760 x 1760 yards

1.25 miles = 2,200 yards

Rounding to the nearest tenths.

1.3 miles = 2,200 yards

Thus,

There are 1.3 miles in 2,200 yards.

#SPJ5

Answer:

1.25 mi

Step-by-step explanation:

First, we want to convert a yard into feet; recall 1 yard = 3 feet.

Then we want to divide that by the number of feet in a mile 1 mile = 5280feet.

So 2200*3 =6600, then divide by 5280

6600/5280 = 1.25 mi

2200 yard is 1.25 miles

The perimeter of an equilateral triangle is 12\/3 cm. Find the radius, apothem and area of the equilateral triangle.

Answers

Answer:

Radius - 4

Apothem - 2

Area - $12√(3)$ or 20.8

Step-by-step explanation:

Try to draw out my explanation so you know what this looks like.

~~~~

This is an equilateral triangle, so all sides are the same length. The perimeter can be divided by 3 to get each side length...

$12√(3) /3 = 4√(3)$

Now that we know the side lengths, we can get this started!

~~~~

Now, an equilateral triangle has angles that all equal 60 degrees. We can bisect this into TWO special case triangles of measures 90-60-30.

4 times the square root of 3 will be the hypotenuse, and the smallest leg is always half of that. The larger leg is represented as the small leg times the square root of 3.

$Small=2√(3) \nHypotenuse = 4√(3) \nLong =6$
