Answer:
3in up per foot across
Step-by-step explanation:
4ft across 12in height
6ft across 18in height
So for every 2ft it goes up 6” which is a ratio of 1ft:3in so the answer to the rate of change is 3in up per 1ft across
Something that you should remember is that the sum of the angles of a triangle add up to 180°.
Since we are given 100° and that the other two angles are equal, we can set up an equation like this:
, where x is the 2 angles.
Doing the math, the measure of each unknown angles is 40°.
24/72
Simplify the fraction, by dividing out the GCF: 24
<u>24/24
</u>72/24
1/3
Answer:
A
Step-by-step explanation:
clearly, the equation has to allow t=0, and for that point we need to get 100% (of carbon-14) as result.
and so we also see, that the function calculates the % of the remaining carbon-14.
so, we need the desired outcome 60(%),
because 60 = 100 - 40.
and again, we need a function that shows t=0.
the only answer option fulfilling both criteria is A.
B divides in the exponent by t, so t=0 is not in the domain of the function.
and C and D aim for the wrong remaining percentage.
