Step-by-step explanation:
9.1 h + 11.6 t = 9.98(60)
9.1 h + 11.6 t = 598.8 ........ (1)
h + t = 60 ........ (2)
h = 60 - t
9.1(60 - t) + 11.6 t = 598.8
546 - 9.1 t + 11.6 t = 598.8
2.5 t = 52.8
t = 52.8 ÷ 2.5 = 21.12 ≈ 21 (lb.)
h = 60 - 21.12 = 38.88 ≈ 39 (lb.)

much money is in each savings account after 14 years. According to the graph, who will have more money
by year 20, and why?
Daniel, because his money is increasing exponentially.
O Daniel, because his money is increasing linearly.

What are exponential functions?When the expression of function is such that it involves the input to be present as exponent (power) of some constant, then such function is called exponential function. There usual form is specified below. They are written in several such equivalent forms.
For example, [tex]y = a.b^x[/tex] , where a is a and b are constants is an exponential function.
How to calculate simple interest's amount?If the initial amount (also called as principal amount) is P, and the interest rate is R% annually, and it is left for T years for that simple interest, then the interest amount earned is given by:
[tex]I = \dfrac{P \times R \times T}{100}[/tex]
How to calculate compound interest's amount?If the initial amount (also called as principal amount) is P, and the interest rate is R% per unit time, and it is left for T unit of time for that compound interest, then the interest amount earned is given by:
[tex]CI = P(1 +\dfrac{R}{100})^T - P[/tex]
The final amount becomes:
[tex]A = CI + P\\A = P(1 +\dfrac{R}{100})^T[/tex]
Usually these two rates are used on money. The compound interest is exponential as it has power T as a variable, but for simple interest, there is no variable exponent.
Both are positive, and growth of exponential function is always going to surpass the growth of linear function (can be proven by derivatives).
Since we are not given the function's equation, we cannot correctly calculate the value just from graph, but as in 14 years, the blue line is already close to red line so it will likely cross it after 6 more years (thus total 20 years) because of good growth.
Thus, the person who will have more money by year 20 is given by: Option C: Tyler, because his money is increasing exponentially

The perimeter of a rectangle is
30m. The length of the rectangle is
3 m more than twice the width. Find
the dimensions of the rectangle
a. 3m x 12m
b 4m x 11m
c 8m x 7m
d 6m x 9m
Answers
Equation for Perimeter of a rectangle: Perimeter = 2W + 2L
Defining the variables, let
Width = xLength = 2x+3 (3 more than twice the width)
Plugging everything into the equation
30= 2(x) + 2(2x+3) using the distributive property,30=2x+4x+6 combining like terms30=6x+6 subtracting 6 from both sides,24=6x divide both sides by 64=x This means that the width is 4 m.To get the length, use the expression L=2x+3 and plug in x = 4 that was already solved forL=2(4)+3L=8+3 = 11 m
So the dimensions of the rectangle are width is 4 m and length is 11 m.
The Boston Red Sox had 949 runs in their 2004 season. In their 2015 season, they had 748 runs. Find the rate of change in runs.
Answers
Answer: -18.27 per year
Step-by-step explanation:
The difference in years is:
= 2015 - 2004
= 11 years
In those 11 years, the runs decreased from 949 to 748.
The total decrease is:
= 949 - 748
= 201 runs
The rate of change is:
= 201 / 11
= 18.27 per year
Since it is reducing, the rate is:
= -18.27 per year
Sandra buys stamps that cost $0.65 each she spends a total of $158.60 on the stamps. To determine how many stamps she buys, she needs to divide $158.60 by $0.65
Answers
Answer:
True
Step-by-step explanation:
When she divides both numbers, she can find out how many stamps she bought. When you solve the equation, we can see that she bought 244 stamps. We can check this by doing inverse operations. 244 x 0.65 (the price for each stamp) = 158.60

Find the volume, given that the apothem is 11.3 in. (hint: remember for regular polygons, A = 2 (apothem) (Perimeter) Round your answer to the nearest - tenth.
Answers
Answer:
V = 3085 in³
Step-by-step explanation:
The volume is given by:
[tex] V = A*h [/tex]
Where:
A: is the area
h: is the height = 7 in
The area of the polygon can be found by using the given equation:
[tex] A = \frac{1}{2}a*p [/tex]
Where:
a: is the apothem = 11.3 in
p: is the perimeter
The perimeter is:
[tex] p = 13*6 = 78 in [/tex]
Hence, the volume is:
[tex] V = A*h = \frac{1}{2}a*p*h = \frac{1}{2}11.3 in*78 in*7 in = 3085 in^{3} [/tex]
