Answer:
(3+2)
Step-by-step explanation:
Perimeter of a square = 4L
L is the length of one side of the square
Given the expression 12 + 8 that represents the perimeter of a square, factoring out 4 from both terms;
12 + 8
= (4*3)+(4*2)
= 4(3+2)
Comparing with 4L
4L = 4(3+2)
Divide both sides by 4
4L/4 = 4(3+2)/4
L = (3+2)
Hence the expression that represents one side of the square is (3+2)

( 3[tex]x[/tex] - 5 ) ( [tex]x[/tex] + 1 )
Step-by-step explanation:
[tex]3x^{2}[/tex] - 2[tex]x[/tex] - 5
(Multiply 3 from [tex]3x^{2}[/tex] with -5)
Product = -15
Sum = -2
(3 times - 5 gives the product '-15' and 3 plus -5 gives the sum -2)

Answer:
h = 13ft
Step-by-step explanation:
We can assume that the triangles are similar, so:
5 ft is to 26 ft as 2.5 ft is to h ft.
Which can be set up like this:
[tex]\frac{5}{2.5}=\frac{26}{h}[/tex]
We can cross multiply:
5h = (2.5) (26)
5h = 65
h = 13ft

Robert is an avid runner who as a specific route he runs each morning. He leaves his house and runs 3
miles north before stopping for a 1 minute break. After his break he runs 4 miles east before taking a 2
minute break. Next he runs 5 miles southwest back to his home. What is his average speed if the route
without the breaks takes 57 minutes to complete?
Answer:
he's running 4/19 miles per minute or 12.6 miles per hour
Step-by-step explanation:
he is running 3 miles north, 4 miles east, and 5 miles southwest, a total of 12 miles
d = rt
12 = 57r
r = 12/57 or 4/19 (simplest form)
this is 4/19 miles per minute, multiply by 60 and it's about 12.6 miles per hour
Darlene has a job babysitting. On the first day, she made x dollars. On the 2nd day, she made three times the amount, and on the third day, she made $6 more than the first day. How much money did Darlene make if he made $30 the first day?
Answer:
Total earned= $156
Step-by-step explanation:
Giving the following information:
On the first day, she made $30.
On the second day, she made three times the amount of the first day.
On the third day, she made $6 more than the first day.
We know the amount that she made the first day.
Second day= 30*3= $90
Third day= 30 + 6= $36
Total earned= 30 + 90 + 36
Total earned= $156

Question 1
Graph y=15x+3.
Question 2
Identify the x-intercept
Answer:
X-intercept: (-0.2,0)
Step-by-step explanation:
y=15x+3
I don't know how to show a graph but what you do is start by plotting (0,3) and go up 15 and over 1 to form a line (because the slope is 15).
To find the x-intercept, replace y with 0 and solve for x.
0=15x+3
-3=15x
-3/15
-1/5 (or -0.2)
(-0.2,0)

Strontium is a radioactive material that decays with a continuous rate (k) of -0.0244. If there are 30 grams of strontium present today and it decays continuously, how much will be present in 20 years?
Answer:
18.42 g
Step-by-step explanation:
Using the exponential growth / Decay function :
A = Pe^kt
A = final amount ; P = initial amount, t = number of years ; t = 20
A = 30e^-(0.0244 * 20)
A = 30e^-0.488
A = 30 * 0.6138528
A = 18.415586
Strontium present after 20 years will be :
18.42 g

A 4-foot tree was planted in 1984. The tree grows continuously by 22% each year from this point forward. Find the height of the tree after 8 years.
Answer:
the tree will be 11.04 feet tall
Step-by-step explanation:
4 x 0.22 (22%) = 0.88
every year it grows 0.88 foot.
0.88 x 8 = 7.04
4 + 7.04 = 11.04 feet tall
sorry if this is wrong!
The height of the tree after 8 years will be 11.04 feet.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that a 4-foot tree was planted in 1984. The tree grows continuously by 22% each year from this point forward.
The height after 8 years will be calculated as:-
4 x 0.22 (22%) = 0.88
Every year it grows 0.88 feet.
0.88 x 8 = 7.04
4 + 7.04 = 11.04 feet tall

Oxygen is being added to a canister which originally contained 5 cubic feet of the gas at
the rate of 0.3 cubic feet per second.
Which function represents the volume, V(t), of oxygen in the cylinder after t seconds of
adding the gas?
Answer:
The change is negative, since the volume in the final state is smaller than the volume in the initial state. 2.25 We express V for the ideal gas as a function of T , p and n: V (T , p, n) = ... each smooth part of the curve and add the integrals, used up yearly by living organisms, which means that even if the oxygen supply was.
Vt = 0.3t + 5 is a function that depicts the volume, V(t), of oxygen in the cylinder after introducing the gas for t seconds.
What is Volume?
Volume is defined as the space occupied within the boundaries of an object in three-dimensional space. It is also known as the capacity of the object.
Given, Oxygen is being added to a canister that originally contained 5 cubic feet of the gas at the rate of 0.3 cubic feet per second.
Let V is the volume of oxygen t be the time in seconds and Vt be the changing volume at time t.
From the formula of volume of a cylinder (V) = π r²h
The initial volume of gas = 5 feet
gas added at the rate = 0.3 feet per second
Thus equation for volume = 5 + 0.3t
Vt = 0.3t + 5
therefore, a function that represents the volume, V(t), of oxygen in the cylinder after t seconds of adding the gas is Vt = 0.3t + 5.
