Answer:
x= 12
Step-by-step explanation:
The perimeter of a rectangle is the sum of the lengths of all its sides.
Formula
Perimeter of rectangle= 2(width) +2(length)
Substitute the given information into the formula:
92= 2(2x +3) +2(x +7)
Expand:
92= 4x +6 +2x +14
92= 6x +20
Subtract 20 from both sides:
6x= 92 -20
6x= 72
Divide both sides by 2:
x= 72 ÷6
x= 12

The sum of two numbers is 14. Using x to represent the smaller of the two numbers , translate "the sum of twice the smaller number and two more than the larger number" into a variable expression. Then simplify
The smaller number is 4 and the larger number is 10.
Given that, the sum of the two numbers is 14.
What is an equation?In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, x represents the smaller of the two numbers.
Then the larger number is
The sum of twice the smaller number and two more than the larger number = 2x+2
Now, x+2x+2=14
⇒3x+2=14
⇒3x=12
⇒x=4
So, 2x+2=10
Therefore, the smaller number is 4 and the larger number is 10.

Answer:
k = 110
Step-by-step explanation:
You want the integer multiple of pi that is the area of 300° of a donut with inner radius 8 cm and outer radius of 14 cm.
Area of a circleThe area of a circle is given by the formula ...
A = πr²
Then the area of the outer circle is ...
A = π(14 cm)² = 196π cm²
The area of the inner circle is ...
A = π(8 cm)² = 64π cm²
Donut areaThe area of the whole donut is the difference of these areas:
whole donut area = (196 -64)π cm² = 132π cm²
Shaded areaThe shaded area of the figure represents 300° of the 360° full donut. The area is proportional to the central angle, so the shaded area is ...
shaded area = (300°/360°)×whole donut area
shaded area = 5/6 × 132π cm² = 110π cm²
Comparing this to the expression kπ cm², we see that ...
k = 110

Points L, M, and N are collinear. You are given LM = 21 and LN = 35.
What is a possible value of MN ?
The value of MN is 14 when the Points L, M, and N are collinear.
As per the question statement, we are supposed to find the possible value of MN when the Points L, M, and N are collinear.
Also, LM=21 and LN=35
As LN is greater than LM, point M has to be in between L and N for practicality and question existence.
[tex]LM+MN=LN\\MN=LN-LM\\LN=35\\LM=21\\MN=35-21\\MN=14[/tex]
Hence final answer is MN = 14

Timothy deposited $2,780.20 in a savings account that earns 4.3% simple interest. What will Timothy's account balance be in 7 months?
Total balance in the account after 7 months is 2849.737$
It is given that Timothy deposits $2780.20 in a savings account
It is given that rate of interest is 4.3 % and it of the simple interest nature.
We are required to find the account balance of Timothy's account in 7 months
We know that formula of simple interest is given by
(principal x rate x time)/100
where principal is the amount put for investing
rate is the rate at which the person is going to earn
time is the time for which the amount is to be invested
Now the time that is given to us in the form of months and hence we must convert it into years form
1 year =12 months
therefore, 7 months = 7/12 years
Now applying this value to calculate the simple interest earned
Let the simple interest be 'SI'
principal = $2780.20
rate = 4.3%
time = 7/12 years
SI= (2780.20x 4.3 x 7)/100 x 12
= 69.737$
The balance in Timothy's account will be original amount + the simple interest
Total balance after 7 months = 2780.20+69.737
=2849.937$
Hence total balance in the account after 7 months is 2849.737$

Suppose that the world's current oil reserves is
R=1970 billion barrels. If, on average, the total reserves is decreasing by 24 billion barrels of oil each year, answer the following:

C.) If no other oil is deposited into the reserves, the world's oil reserves will be completely depleted (all used up) approximately_______years from now.
(Round your answer to two decimal places.)
From the given situation, we have that:
A) The linear equation is R(t) = 1970 - 24t.
B) 12 years from now, the total oil reserves will be 1682 billions of barrels.
C) Approximately 82.08 years from now.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For this problem, the parameters are given as follows:
b = 1970, m = -24.
Hence the linear function is:
R(t) = 1970 - 24t.
For item b, the amount is of R(12), hence:
R(12) = 1970 - 24(12) = 1682.
12 years from now, the total oil reserves will be 1682 billions of barrels.
For item c, we have to solve for t when R(t) = 0, hence:
1970 - 24t = 0
24t = 1970
t = 1970/24
t = 82.08.

Step-by-step explanation:
note: the editor will not let me use eff of x. I have to use g(x)
Equation
g(x) = -2x^2 -4x + 13
Comment
y is the same thing as g(x) so you are really being asked to find y,
Given
x = - 7
g(-7) means that x is -7
Solution
g(x) = -2(-7)^2 - 4(-7) + 13 Substitute x = - 7 on the right
g(x) = -2*49 + 28 + 13 Combine
g(x) = -98 + 28 + 13

The temperature will be 44.2f when the plane reaches an altitude of 8,000ft.
What exactly are mathematical operations?A function in mathematics that converts zero or even more input values (also known as "operands" or "arguments") to a well-defined output value is known as an operation.The number of operands determines the operation's arity.The most commonly studied operations are binary activities (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive direct opposite and multiplicative inverse.A constant is a zero-arity operation, also known as a nullary operation.An arity 3 operation, also recognized as a ternary operation, is the mixed product.So, there is a 1.2f drop in temperature for every thousand feet.
The plane is at 8000 ft then:
8000/1000 = 8So,
1.2 × 8 = 9.6The temperature at 8000 ft:
53.8 - 9.6 = 44.2Therefore, the temperature will be 44.2f when the plane reaches an altitude of 8,000 ft.

The number of sections of board that he can construct will be equal to 7.
We are given that:
A carpenter has 6 boards.
Length of each board = 7 / 8 yard long
Now, we will use multiplication.
Total length of cardboards available = 7 / 8 × 6 yards
Total length = 42 / 8 yards
Total length = 21 / 4 yards.
Now, 3/4 yard sections of board that he can construct will be:
Number of sections of board = 21 / 4 ÷ 3 / 4
Number of sections of board = 21 / 3
Number of sections of board = 7

If the demand function for a commodity is given by the equation p2 + 16q = 1200 and the supply function is given by the equation 300 − p2 + 10q = 0, find the equilibrium quantity and equilibrium price. (Round your answers to two decimal places.)
The equilibrium quantity and equilibrium price are 34.62 and 25.42 respectively
How to find the equilibrium quantity and equilibrium price?The functions are given as
Demand: p^2 + 16q= 1200
Supply function: 300 - p^2 + 10q
Rewrite the demand function as
p^2 + 16q - 1200 = 0
At equilibrium, demand = supply
So, we have:
p^2 + 16q - 1200 = 300 - p^2 + 10q
Using a graphing calculator, we have:
p = 25.42 and q = 34.62
