We can answer the problem using a rule of three, simple, direct proportion and also using fractions. First the rule of three:
8 apples ------> 15 min
16 apples ----> x
x = (16)(15)/8
x = 30
therefore he can eat 16 apples in 39 minutes.
We can also equate fractions like so:
8/15 = 16/y
and solve for y:
y = 15*16/8
y = 30

Answer:
Step-by-step explanation:
<2 + <1 + 20 = 180 A straight line has 180 degrees.
<2 is given as 90 degrees.
90 + <1 + 20 = 180 Combine like terms
<1 + 110 = 180 Subtract 110 from both sides
<1 = 180 - 110
<1 = 70
<1 + <2 + <3 = 180
<1 = 70
<2 = 90
70 + 90 + <3 = 180
160 + <3 = 180 Subtract 160 from both sides
<3 = 180 - 160
<3 = 20
20 + 20 + <4 = 180 Straight line theorem stated above.
40 + <4 = 180 Subtract 40 from both sides
<4 = 180 - 40
<4 = 140
The average rate of change is 4.
<h3>What is function?</h3>
An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
The rate of change in interval [0, 2]
r=[h(2)-h(0)]/2
h(2)=(2)²+2(2)-6
h(2)=4+4-6
h(2)=2
h(0)=(0)²+2(0)-6
h(0)=0+0-6
h(0)=-6
So, r=[h(2)-h(0)]/2
r=[2-(-6)]/2
r=(8)/2
r=4
