Answer:

230

Step-by-step explanation:

This year: 319 total; 33 unpopular

Last year: 394 total; 197 unpopular

Total songs over both years 319 + 394 = 713

Total unpopular over both years 713 - 483 = 230

2. 3/4(-4 + 4x) = -3 + 3x 3/4 times 4 is 3, so if you distribute 3/4 (-4 + 4x), you will get -3 + 3x.

3. -0.113(-4x - 4) = 0.452x + 0.452 0.113 times 4 is 0.452, but you need to make sure to have the correct signs. Since the product is positive and -0.113 is negative, you would have to multiply it by a negative to get the product.

If you're having trouble with multiplying by fractions, just use repeated addition in your head. For example, for the first problem, instead of trying to tackle 3/4 times 4, think 3/4 + 3/4 + 3/4 + 3/4.

3/4 + 3/4 = 6/4
6/4 + 3/4 = 9/4
9/4 + 3/4 = 12/4
12/4 = 3

For the second problem, when multiplying by a decimal, just do what you'd normally do for multiplication. When you get to the end, count how many digits you had behind the decimal before, and put the decimal in the corresponding space for the answer.

0.113
x 4
0452

There are 3 digits behind the 0 in 0.113, so there should be 3 digits behind the decimal in the answer. So, the answer should be 0.452.

Hope this helps!

The ice cream cone consists of a semi-circle with a diameter of 10 cm and a triangle with a base of 10 cm and height of 12 cm.

The area of a semi-circle is half the area of a full circle, so we can find it by using:

$A= \frac{1}{2} \pi r^2$

If the diameter of the circle is 10 cm, then the radius is 5 cm. Plug in the known values:

$A= \frac{1}{2} \pi (5)^2$

$A = 12.5 \pi$ or about 39.25

The area of a triangle is:

$A = \frac{1}{2} bh$

So we can plug in the known values to find the area to be:

$A= \frac{1}{2} (10)(12)=60$

When we add the areas of the two sections together, we get an exact answer of:

(60 + 12.5pi) cm^2

or about 99.25 cm^2
