Answer:

52%

Step-by-step explanation:

First, find the difference between this year's sales and the previous'. 1500-990=510.

Now we can divide 990 by 510 to find the percent increase. 510/990=0.515151515152, or 52%.

A small school had 60% boys and the rest are girls if the number of boys is 48 what is the total number of boys and girls all to

Flura [38]

Hey there!

When dealing with percent word problems, the word "is" means equals. Let's see what we can do with your problem.

If the small school had 60% boys, it will have 40% girls. The number of boys is 48, which should equal 60% of the total, which we can model below, with t representing the total number of kids. In decimal form, 60% is 0.6.

0.6t=48

We divide both sides by 0.6.

t=80

Therefore, there are 80 total kids at the school.

We can also check our answer below.

BOYS: 0.6(80)= 48

GIRLS: 0.4(80)=32

48+32=80

I hope that this helps!

Which big these flags will have the greatest area? Why?

svetoff [14.1K]

<h2>Question 1:</h2>

The area of flag b is the greatest.

Explanation:

Area of triangle = $\frac{1}{2}base*height$

Area of parallelogram = base * height

For flag A:

It is a triangle with base = b and height = a

Area of flag A = $\frac{1}{2}a*b$ square units

For flag B:

It is a parallelogram with base = a and height = b

Area of flag B = a*b square units

For flag C:

It is a triangle with base = b and height = a

Area of flag C = $\frac{1}{2}a*b$ square units

From the above, we can conclude that the area of the parallelogram (flag B) is the greatest

<h2>Question 2:</h2>

The perimeter of flag C is shorter than that of flag A

Explanation:

Perimeter is the sum of the three sides of the figure

For flag C:

The three sides are given as a, b and c

Therefore, perimeter of flag c = a + b + c units

For flag A:

We are given two sides as b and c and we are given that the height is a

We know that in the given flag, the third side (the unknown slant one) will be longer than the height of the height of the triangle

Therefore, the third side = a + k where k is a constant

Therefore, perimeter of flag A = a + b + c + k units

From the above, we can conclude that the perimeter of flag C is shorter

Hope this helps :)
