Area of the square bed room is given. From this area, we need to find the sides of the square by taking square root of the area.
Side of the square bedroom = √area
[tex]= \sqrt{121} = \sqrt{11*11}\\\\= 11 \ ft[/tex]
Perimeter = 4 * side
= 4 *11
= 44 ft

% compounded continuously. After 15 years, how much more money would Lillian have in her account than Melanie, to the nearest dollar?
Answer:
$8727
Step-by-step explanation:
The difference in investment values can be found by computing the value of each investment, then finding the difference. Here, we're concerned with investments compounded quarterly and compounded continuously.
a)Melanie's investment value is computed using the formula ...
FV = P(1 +r/n)^(nt) . . . . where P is the principal, r is the annual rate, t is the number of years
FV = $63,000(1 +0.07125/4)^(4×15) = $63,000(1.0178125^60)
FV = $181,721.94
__
b)Lillian's investment value is computed using the formula ...
FV = Pe^(rt)
FV = $63,000·e^(0.07375×15)
FV = $190,449.05
__
c)The amount more that Lillian has is ...
$190,449.05 -181,721.94 = $8,727.11
Lillian has about $8727 more than Melanie.

A net has a square at the center and 4 triangles on the sides. The square has side lengths of 2 yards. The triangles have a base of 2 yards and height of 3 yards.
What is the surface area of the square pyramid?
The surface area is
yd2.
Answer:
16 yd²
Step-by-step explanation:
The total surface area is the sum of the area of the square base and the 4 triangular sides.
SA = s² + 4 × bh/2
SA = (2 yd)² + 4 × (2 yd)(3 yd)/2
SA = 4 yd² + 12 yd²
SA = 16 yd²
Answer:
16

A rectangular prism has a length of 412 centimeters, a width of 412 centimeters, and a height of 6 centimeters. Sally has a storage container for the prism that has a volume of 143 cubic centimeters.
What is the difference between the volume of the prism and the volume of the storage container?
Enter your answer in the box as a simplified mixed number or a decimal.
cm³
Answer: First find the volume of the rectangle prism. Do this by multiplying all three dimensions. 412 x 412 x 6 = 1,018,464.
Subtract 1,018,464 from 143.
You should get 1,018,321 mm^3
(Remember that the units are cubed because you multipled 412 mm x 412 mm x 6 mm which is multiplying not only the numbers, but the mm three times as well.)

Which expressions are equivalent to 7(-4/3 x -3)? Select two options.
Answer:
Step-by-step explanation:
7(-3/4x-3) is the same as
7(-3/4x)-7(3) and
-5 1/4x-21
Let me explain this a little bit more.
If you take the 7 times the first part or -3/4x you get 7(-3/4x) You take 7 times the second part you get -7(3)
When you actually solve them:
7(-3/4x) = -5 1/4x and -7(3) = -21.

Solve for x 64^x^2 = 256^x
Answer:
x = 0, 1.333333...
Step-by-step explanation:
1) Convert both sides to the same base.
[tex]16^{1.5x^{2} } =16^{2x}[/tex]
2) Cancel the base of 16 on both sides.
[tex]1.5x^{2} =2x[/tex]
3) Move all terms to one side.
[tex]1.5x^{2} -2x=0[/tex]
4) Factor out the common term x.
[tex]x(1.5x-2)=0[/tex]
5) Solve for x.
1 - Ask: When will x(1.5x-2) equal zero?
When x = 0 or 1.5x - 2 = 0
2 - Solve each of the 2 equations above.
x = 0, 1.333333...

You have 12 coins. Some quarters and dimes. You have a total of $2.40, how many of each coin do you have?
Answer:
8 quarters and 4 dimes
Step-by-step explanation:
4 quarters = 1 dollars
4 quarters = 1 dollars
4 dimes = 40 cents
2.40$
============================================
Work Shown:
d = number of dimes
q = number of quarters
1 dime = 10 cents
d dimes = 10d cents
1 quarter = 25 cents
q quarters = 25q cents
d+q = 12 since we have 12 coins total
q = -d+12 after solving for q
10d+25q = total value in cents
10d+25q = 240
10d+25(-d+12) = 240 ... plug in q = -d+12
10d-25d+300 = 240
-15d+300 = 240
-15d = 240-300
-15d = -60
d = -60/(-15)
d = 4
q = -d+12
q = -4+12
q = 8
Since d = 4 and q = 8, this means we have 4 dimes and 8 quarters
-----------------------------
Check:
4 dimes = 4*10 = 40 cents
8 quarters = 8*25 = 200 cents
(4 dimes) + (8 quarters) = (40 cents) + (200 cents) = 240 cents
240 cents = 240/100 = $2.40
We have 4+8 = 12 coins total
The answers are confirmed

A triangle has an area of 66 in2. If the base is 11 inches, what is the height?

Explanation:The area of a triangle is given by the following formula:

[tex] \left[ \begin{array}{c c c} \underline{\tt Area \ of \ a \ triangle \text{:}} \\ ~ \\ \tt A = \dfrac{B \cdot H}{2} \end{array} \right] [/tex]

[tex] \\ [/tex]
Substitute these values into the formula and solve for H.
[tex] \sf A = \dfrac{B \cdot H}{2} \\ \\ \\ \longrightarrow \sf 66 \ in^2 = \dfrac{11 \ in \cdot H}{2} [/tex]
[tex] \\ [/tex]
Multiply both sides by 2:
[tex] \longrightarrow \sf 66 \ in^2 \cdot 2 = \dfrac{11 \ in \cdot H}{2} \cdot 2 \\ \\ \\ \longrightarrow \sf 132 \ in^2 = 11 \ in \cdot H [/tex]
[tex] \\ [/tex]
Divide both sides by 11in :
[tex] \longrightarrow \sf \dfrac{132 \ in^2 }{11 \ in } = H \\ \\ \\ \longrightarrow \boxed{\boxed{\sf H = 12 \ in}} [/tex]

A triangle has an area of 66 in². If the base is 11 inches, what is the height?
Answer:The height of the triangle is 12 inches.
Step-by-step explanation:As per the provided information in the given problem, we know that the area of a triangle is given by 66 inches². The base of the triangle is given by 11 inches. In this problem, we are tasked to find the height of the triangle.
To do this, we will use the formula below:

Where:
The base is denoted as b.The height is denoted as h.Substitute the given values into the formula given earlier and solve for h:
[tex]\Large\begin{aligned}\rm\dashrightarrow{Area_{(Triangle)}}& = \rm{\dfrac{1}{2}bh}\\\rm\dashrightarrow{66\: in^2}& = \rm{0.5(11\: in)(h)} \\\rm\dashrightarrow{66\: in^2}& = \rm{(5.5\: in)(h)} \\\rm\dashrightarrow{\dfrac{66\: in^{\cancel{2}}}{5.5\: \cancel{in}}}& = \rm{\dfrac{(\cancel{5.5\: in})(h)}{\cancel{5.5\: in}}} \\\rm\dashrightarrow{12\: in}& = \rm{h}\end{aligned}[/tex]

Regina currently makes $15 an hour. Her boss decided to give her a 7% raise. Write the expression she would use to determine how much more she will make per hour.
Answer:
[tex]\frac{7\times15}{100}[/tex]
Step-by-step explanation:
Given the following question:
7% of 15
To find the answer we need to use the formula to calculate percentages in which we multiply the percentage by the whole number and then divide that answer by 100, of course rounding to the nearest cent if needed.
[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{7\times15}{100}[/tex]
[tex]7\times15=105[/tex]
[tex]105\div=1.05[/tex]
[tex]=1.05[/tex]
7% of 15 is "1.05" which means Regina receives a $1.05 raise.
