A square has an area of 200 square feet. How long is each side in simplest radical form? If I increase the length of each side by 2, what is the new area in simplest radical form?
Answer:
a) 14.14 feet
b) 260.5 square feet
Step-by-step explanation:
A square has an area of 200 square feet.
a) How long is each side in simplest radical form?
Area of a square = (side length)²
Side length = √Area
Side length = √200 square feet
= 14.142135624 feet
≈ 14.14 feet
b) If I increase the length of each side by 2, what is the new area in simplest radical form?
= 14.14 feet + 2
= 16.14 feet
New area = (16.14 feet)²
= 260.4996 square feet
Approximately = 260.5 square feet

Step-by-step explanation:
A ton is 2000 lbs -> w = 2000
Weight in an elevator must be less than 2000 -> w<2000
The pool must hold atleast 2000 lbs w >= 2000 (>= is greater than equal to)
The scale...... -> w<= 2000
My car weighs more than 2000 -> w > 2000
Answer:

7. Jerry has 23 coins in nickels, n, and dimes, d. He
has $1.95 altogether. How many nickels does Jerry
have?
Answer:
17 nickles !
Step-by-step explanation:
First, identify the variables:
n = amount of nickels
d = amount of dimes
Next, setup the equations based on what you know. The first equation is:
n + d = 28
For the second equation, we know that a dime is worth 10¢ and a nickel is 5¢, so it should be:
0.05n + 0.10d = 1.95
This a three-step answer:
In one formula (you can use any of them; most people use the simplest one), single out the variable on one side
Apply the first formula into the second formula, and solve it to get the value of one variable
Apply the answer from the second formula into the first formula, and solve it to get the value of the other variable
======
Step One:
n + d = 28
n + d - d = 28 - d
n = 28 - d
Step Two:
0.05n + 0.10d = 1.95
(0.05 * (28 - d)) + 0.10d = 1.95
1.40 - 0.05d + 0.10d = 1.95
1.40 + 0.05d = 1.95
1.40 - 1.40 + 0.05d = 1.95 - 1.40
0.05d = 0.55
d = 11
Step Three:
n = 28 - d
n = 28 - 11
n = 17
======
Your answer should be 17 nickels and 11 dimes.
You can double check by applying the variables into both formulas.
n + d = 28
17 + 11 = 28
28 = 28
0.05n + 0.10d = 1.95
(0.05 * 17) + (0.10 * 11) = 1.95
0.85 + 1.10 = 1.95
1.95 = 1.95
I hope this helped.
All sides of ∆ABC are tangent to circle P.
What is the perimeter of triangle ABC?
Answer:
[tex]Perimeter =58[/tex]
Step-by-step explanation:
Given
[tex]AB = 24[/tex]
See attachment
Required
The perimeter of ABC
First, calculate the lengths of AC and BC.
From the attachment.
[tex]Ax = Az =10[/tex]
[tex]Cx = Cy = 5[/tex]
[tex]By =Bz[/tex]
So, we have:
[tex]AC = 10 + Cx[/tex]
[tex]AC = 10 + 5[/tex]
[tex]AC = 15[/tex]
Also:
[tex]Az + Bz = AB[/tex]
[tex]Az + Bz = 24[/tex]
Recall that: [tex]Ax = Az =10[/tex]
So:
[tex]10 + Bz = 24[/tex]
[tex]Bz = 24 - 10[/tex]
[tex]Bz = 14[/tex]
So, we have:
[tex]By = Bz = 14[/tex]
To calculate BC, we have:
[tex]BC = 5 + By[/tex]
[tex]BC=5+14[/tex]
[tex]BC = 19[/tex]
The perimeter is then calculated as:
[tex]Perimeter = AB + BC + AC[/tex]
[tex]Perimeter = 24 + 19 + 15[/tex]
[tex]Perimeter = 58[/tex]

Step-by-step explanation:
Given the expression
2/6 + 1/6
Find the LCM
[tex]= \dfrac{2+1}{6} \\= \dfrac{3}{6} \\= \dfrac{3*1}{3*2}\\= \dfrac{3}{3} * \dfrac{1}{2} \\= 1 * \dfrac{1}{2}\\= \dfrac{1}{2}[/tex]

AD is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides , that is
[tex]\frac{28}{x}[/tex] = [tex]\frac{8}{14}[/tex] ( cross- multiply )
8x = 392 ( divide both sides by 8 )
x = 49

Cecilia has $780 in an account earning 5.2% simple interest. How much more interest would her account earn in 6 years with annually-compounded interest?
Answer:
$1057.3
Step-by-step explanation:
First we'll find the Interest no. 1, which is simple interest, assuming the time 1 year:
S.I= PRT/100
S.I= 780*5.2*1/100
S.I=$40.56
Now we'll find interest no.2, which is compound interest, time is 6 years, Principal amount (780) will remain the same as well as the rate thus (putting in the formula of compound interest- annual- [tex]A=P(1+\frac{R}{100} )^t[/tex]):
[tex]A= 780(1+\frac{5.2}{100})^6[/tex]
A= $1057.3

On January 1, one share of stock in the LMNOP Corp was worth $85. By
December, it lost 11.6% of its value. What is the new value of one share of LMNOP
stock?
Answer:
$75.14
Step-by-step explanation:
The new value of one share of LMNOP stock after 11.6% increment is $75.14
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
For this case, we are given that:
Initial price of the stock = $85/shareFinal price of the stock in December = initial price - 11.6% of initial price (since it lost 11.6% of its initial value, so decrement, which is denoted by subtraction).Now, the 11.6% of initial price is:
[tex]\dfrac{85}{100} \times 11.6 = \$9.86[/tex]
Thus, the final price of the stock in December = $85 - $9.86 = $75.14

Answer:
The Answer Is E!
Step-by-step explanation:
To solve this equation., you have to try every solution and the only one that perfectly completes both statements is answer E.
We subtract the $1.15 from $2.10 if this is the price of one taco, leaving the price of a small cup of coffees price ($2.10-$1.15=$0.95 for a small cup of coffee
To check it fits both statements, we multiply the price of one coffee by 3 ()$0.95×3=$2.85 for three small coffees\
Next, we multiply $1.15 (one taco) by 2 to fill in the expression ($1.15×2=$2.30)
Finally, we add both the prices of the 3 coffees and two tacos which adds up to a perfect $5.15, justifying the answer
