Answer:
Given function:
t(s) = 3s + 20
where:
- t(s) = number of palm trees grown
- s = number of seeds planted
Given function:
s(d) = 20d
where:
- s(d) = number of seeds planted per day
- d = number of days
To determine the composite function that represents how many palm trees Carlos can expect to grow over a certain number of days, simply substitute s = 20d into t(s) = 3s + 20:
⇒ t(d) = 3(20d) + 20
⇒ t(d) = 60d + 20
The unit of measurement is <u>how many palm trees</u> Carlos can expect to grow <u>over</u> a certain <u>number of days</u>:
Answer:

Step-by-step explanation:
(x-2)(x+7)=90
x^2 +5x -14=90
x^2 +5x -14 -90=90-90
x^2 +5x -104=0
factor it out
(x−8)(x+13)=0
so 8 or -13
Answer:
672 revolutions.
Step-by-step explanation:
Let n represent number of revolutions.
We are asked to find the number of revolutions it will take for a car wheel of diameter 30 in. to travel a distance of one mile.
We know that 1 mile equals to 63360 inches.
We will use circumference of circle formula to solve our given problem.
, where, D represents diameter of circle.
Now, we will set the product of n and circumference of circle equal to 63360 inches as:
Therefore, it will take 672 revolutions for the wheel of car to travel a distance of one mile.

Answer:
The carpenter earned $176 for the week.
Step-by-step explanation:
Add up the hours worked: 3.25 hr + 7 1/4 hr + 5 2/4 hr
= 10 2/4 hr + 5 2/4 hr
= 16 hr
Now multiply this result by $11/hr:
($11/hr)(16 hr) = $176
