Answer:

16.3

Step-by-step explanation:

I'm assuming side a is the hypotenuse.

Cosine rule is a=\sqrt{a^{2} +b^{2}-2ab*cosC }

so \sqrt{10^{2}+8^{2} -2*10*8*cos130} = 16.33542217

The attached picture is a diagram if you are confused

The labelling of the sides doesn't matter as long as the unknown side is c

A store pays $10.56 fora map of Africa and marks the price up by
nignag [31]

Essentially, 50% of $10.56 is $5.28.

This means that all we have to do is add $10.56 to $5.28, making <u>$15.84</u>


Side note: Another way that you can do this is by simply doing 1.5(10.56).

In 2020, there were about 260 million gas powered cars on the road. This number isexpected to decrease at a rate of 1.1% per yea
Amanda [17]

This is an equation of exponential decay

y(t) = a b^ t where a is the initial amount

b is the decay factor

t is the time in years

b is found by taking 1 and subtracting the percent it decreases in decimal form

Letting t =4

y(t) = 260 million * ( 1- .011) ^ 4

=248.7473796 million

=24874737.96

Rounding to a whole number

= 24874738
