Answer:
38%
Step-by-step explanation:
Percentage is 37.5% but you round up
:)
If this is an isosceles triangle, and because of the fact that the sum of angles of any triangle must sum to 180°
(180-40)/2=70°
For one thing, Cal and Martha are <em>technically</em> in agreement; 0.1 and 0.10 are the exact same value. To see whether they're right, or whether Angela had it correct, let's take a look at the numbers 0.5 and 0.2.
As fractions, those two values would be
and
, or
and
when reduced. When you cut the original pizza in half, you cut it into <em>2 equal slices</em>. Cutting each of those two pieces into <em>5 equal pieces</em>, we get a total of 5 x 2 = <em>10 equal slices</em>. So, taking one of those slices at that point - as Angela did - would be taking
- or 0.1 - of the whole pizza.
So,
both Cal and Martha are correct.
Given:
This year's price - 15,795
Increase in price - 5.5%
We simply multiply the rate of increase to this year's price to get the value of increase.
15,795 x 5.5% = 868.725 rounded up to 868.73
Add the value of increase to this year's price to get next year's price.
15,795 + 868.725 = 16,663.725 rounded up to 16,663.73
We can also solve for next year's price by adding 5.5% to 100% and multiplying its sum to 15,795
15,795 * 105.5% = 16,663.725 rounded up to 16,663.73
The following is the solution for the problems given above:
A. The probability that all adults have only a cellphone is P(only cellphone) = 0.49 ^ 4 = 0.0576
B. If 49% only have a cellphone and no landline, then only 51% don’t have this combination of phones, so therefore: P (no one with only a cellphone) = 0.51^4 = 0.0677
C. If at least one of them has a cellphone: P (at least one with cell phone) = 1 – P(cellphone and/or landline) = 1 – (0.51)^4 = 0.9323
