Answer:
<HKJ = 90
<FKG = 42
<FKJ = 138
<IKJ = 42
<FKH = 132
<GKI = 138
Step-by-Step :
<GKH , <HKI , and <IKJ all make up a line. A line is 180 degrees.
90 + 48 = 138 180 - 138 = 42 <IKJ = 42
<FKG is a vertical angle to <IKJ. Vertical angles are congruent.
<FKG = 42
<FKG and <FKJ make up a line. A line is 180 degrees.
180 - 42 = 138 <FKJ = 138
Hope this helps.
3a+20=-25
Subtract 20 from both sides
3a=-45
Divide both sides by 3
a=-15
Final answer: a=-15
9^2 = 4.5^2+b^2
81=20.25+b^2
60.75=b^2
b (altitude) = approx. 7.8
The <em>average</em> rate of change doesn't require calculus.
It's just
(amount of change during some time) / (amount of time for the change) .
You need calculus when you want the <em>instantaneous</em> rate of change . . .
that's the rate of change at a single point in time.
Answer:
264 acres
Step-by-step explanation:
Since 33,000 acres is 100%, 330 acres is 1% because 33000 acres divided by 100 is 330 acres. Then if 330 acres is 1%, 33 acres is 0.1% because 330 acres divided by 10 is 33 acres. 1 divided by 10 is 0.1.
Next 33 acres times 8 because 0.8% is eight times bigger than 0.01%. This equals to 264 acres.
