A square piece of tissue paper has a perimeter of 164 centimeters. How long is each side of the tissue paper?
Answer:
s = 41 cm
Step-by-step explanation:
Since all the sides on a square are equal, we can use this formula for perimeter: P = 4s
Plugging in 164 gives us 164 = 4s, where solving for s gives us s = 41
Colin predicted whether he got answers right or wrong in his 50 question exam. He identified the 14 questions he thought he got wrong. It turns out that Colin got 5 questions right that he thought he got wrong. Colin also got a total score of 35 out of 50 in the test. What is the percentage accuracy he had with predicting his scores?
Number of questions Colin thought wrong, N = 14.
So, his score by his prediction will be, S = 50-14 = 36.
Now,
Number of questions which are actually wrong, n = 14 -5 = 9.
His actual score, s = 50 - 9 = 41.
Percentage accuracy is given by :
[tex]\%=\dfrac{Actual-Real}{Real }\times 100\\\\\%=\dfrac{41-36}{41}\times 100\\\\\%=12.195\%[/tex]
Hence, this is the required solution.

At a bookstore, the cost for a novel and a magazine is $8.27. The cost for 3 novels and 5 magazines is $20.22. Which pair of equations can be used to determine n, the cost of a novel, and m, the cost of a magazine? n + 5m = 8.27 3n + m = 20.22 n + 5m = 8.27, , 3n + m = 20.22, n + m = 8.27 3n + 5m = 20.22 n + m = 8.27, , 3n + 5m = 20.22, n + m = 20.22 3n + 5m = 8.27 n + m = 20.22, , 3n + 5m = 8.27, 3n + m = 8.27 n + 5m = 20.22
Answer:
n + m = 8.27; 3n + 5m = 20.22
Step-by-step explanation:
Let
Cost of the novel = n
Cost of the magazine = m
The cost for a novel and a magazine is $8.27.
n + m = 8.27 (1)
The cost for 3 novels and 5 magazines is $20.22
3n + 5m = 20.22 (2)
The pairs of equation to determine n, cost of the novel and m, cost of the magazine is
n + m = 8.27; 3n + 5m = 20.22
Combining (1) and (2)

Given that x=3sinθ-2 and y=3cosθ+4.Show that (x+2)²+ (y-4)²=9
Answer:
First, plug-in x and y as 3sinθ-2 and 3cosθ+4 into the equation, respectively:
[tex]((3\sin (\theta)-2)+2)^2 + ((3\cos (\theta)+4)-4)^2 = 9[/tex]
Then, +2 and -2 cancel out and +4 and -4 cancel out as well, leaving you with:
[tex](3\sin(\theta))^2+(3\cos(\theta))^2=9[/tex]
We can factor out 3^2 = 9 from both equations:
[tex]9(\sin(\theta)^2+cos(\theta)^2) = 9[/tex]
We know from a trigonometric identity that [tex]\sin(\theta)^2+cos(\theta)^2 = 1[/tex], meaning we can reduce the equation to:
[tex]9(1) = 9[/tex]
[tex]9=9[/tex]
And therefore, we have shown that (x+2)^2 + (y-4)^2 = 9, if x=3sinθ-2 and y=3cosθ+4.
Hope this helped you.
How long does it take an account with a principal of $10,000 to earn $750 in interest if the rate is 15%?_ years
Answer:
The simple interest accumulated
on a principal of $ 10,000.00
at a rate of 3.875% per year
for 5 years is $ 1,937.50.
Step-by-step explanation:
I = $ 1,937.50
Equation:
I = Prt
Calculation:
First, converting R percent to r a decimal
r = R/100 = 3.875%/100 = 0.03875 per year,
then, solving our equation
I = 10000 × 0.03875 × 5 = 1937.5
I = $ 1,937.50
Answer:
The answer should be 1,1125,000 because 10,000x 15 x7.5= 1,1125,000.

A.
21.1 units
B.
20.8 units
C.
13.9 units
D.
12.5 units
The approximate length of line segment XY is 20.8 units
How to calculate the distance between two pointsThe formula for calculating the distance between two points is expressed as:
A = √(x2-x1)²+(y2-y1)²
Given the coordinate points X(–12, –6) and Y(5, 6). The distance between them is expressed as;
XY = √(5+12)²+(6+6)²
XY = √(17)²+(12)²
XY = √269 + 144
XY = 20.8
Hence the approximate length of line segment XY is 20.8 units

Brian took eight years to pay off his $71,900 loan. the loan had an interest rate of 8.16%, compounded quarterly. if brian paid quarterly and made the same payment every time, how much was each payment that he made? a. $2,342.66 b. $3,081.54 c. $1,022.28 d. $1,466.76
The Brian paid amount of every quarter is $ 4287.79.
We have given that Brian took eight years to pay off his $ 71,900 loan, had an interest rate of 8.16%, compounded quarterly,
we have to determine, if Brian paid quarterly and made the same payment every time, how much was each payment that he made,
P=71900
r=8.16
[tex]r=\frac{8.16}{100}=0.0816[/tex]
[tex]i=\frac{r}{n}=\frac{0.0816}{4}= 1.0204[/tex]
for eight years
[tex]4\times 8=32[/tex]
What is the formula for the monthly payment?[tex]monthly payment=P((1+i)^n/n)[/tex]
Where p=present value
r=interest rate
m=number of compounding periods
n=m(t)
t=times in years
i=r/m
Therefore by using the formula we get,
[tex](71900 \times (1 + 0.0816 / 4) ^ {4\times8}) / (8 \times 4) = X[/tex]
[tex](71900 \times 1.0204 ^ {32}) / 32 = X[/tex]
[tex](71900 \times 1.9083) / 32 = X[/tex]
[tex]137209.2177 / 32 = X[/tex]

The table represents the relationship between the number of employees scheduled per estimated customer at a grocery store
Answer: 8 8 4
Step-by-step explanation:the first one is 8 then 8 and then 4
The answers will be ;
a) No. of customers , one employee can help at restaurant is 5.
b) No. of customers , one employee can help at grocery store is 12.
c) The grocery rate of customer per employee is 7 more than restaurant's rate.
A graph for restaurant is given and a table for grocery store is given which represents relation of no. of employees per customer.
We have to solve the subparts of the given question.
What will be the rate if there are 12 customers per 2 employee at a shop ?
The rate at the shop will be 12 ÷ 2 or 6 customers per employee.
As per the question ;
Graph for restaurant is given and a table for grocery store is given.
a)
At restaurant ;
For 2 employees , no. of customers = 10
For 4 employees , no. of customers = 20
So ,
With increase of 2 in number of employees , no. of customers increases by 10.
⇒ No. of customers , one employee can help at restaurant is ;
= 10 ÷ 2
= 5 customers
b)
At grocery store ;
For 2 employees , no. of customers = 24
For 4 employees , no. of customers = 48
So ,
With increase of 2 in number of employees , no. of customers increases by 24.
⇒ No. of customers , one employee can help at grocery store is ;
= 24 ÷ 2
= 12 customers
c)
So ,
The restaurant rate of customers per employee = 5 customers/employee
The grocery store rate of customers per employee = 12 customers / employee
And
The grocery rate of customer per employee is more than restaurant rate by ;
= 12 - 5
= 7
Thus , the answers will be ;
a) No. of customers , one employee can help at restaurant is 5.
b) No. of customers , one employee can help at grocery store is 12.
c) The grocery rate of customer per employee is 7 more than restaurant's rate.

What is the solution to the equation
x = –6
x = –1
x = 1
x = 2
When we're solving equations, our prime goal is to isolate the variable. We can do this by using inverse operations to combine like terms.
Examples:
The inverse operation of addition is subtraction, and vice versa.The inverse operation of an exponent is taking the root of the exponent, and vice versa.Solving the Question[tex]\sqrt[3]{5x-4}=\sqrt[3]{7x+8}[/tex]
⇒ Here, both sides are being taken to the square root of 3. To remove this, we can raise both sides to the power of 3:
[tex](\sqrt[3]{5x-4})^3=(\sqrt[3]{7x+8})^3\\5x-4=7x+8[/tex]
⇒ Let's move our x variable to the right side of the equal sign and the numbers to the left side. Start by subtracting 5x from both sides:
[tex](\sqrt[3]{5x-4})^3-5x=(\sqrt[3]{7x+8})^3\\5x-4=7x+8-5x\\-4=2x+8[/tex]
⇒ Now, subtract 8 from both sides:
[tex]-4-8=2x+8-8\\-12=2x[/tex]
⇒ Finally, divide both sides by 2 to isolate x:
[tex]\dfrac{-12}{2}=\dfrac{2x}{2}\\\\-6=x[/tex]

Step-by-step explanation:
Number each column from least to greatest for quart pint gallon
pint, quart, then gallon
least------------> greatest
2a + 3b + 5a - 4b + 2g
5a+2 =2 (4+a)
Simplifying
5a + 2 = 2(4 + a)
Reorder the terms:
2 + 5a = 2(4 + a)
2 + 5a = (4 * 2 + a * 2)
2 + 5a = (8 + 2a)
Solving
2 + 5a = 8 + 2a
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-2a' to each side of the equation.
2 + 5a + -2a = 8 + 2a + -2a
Combine like terms: 5a + -2a = 3a
2 + 3a = 8 + 2a + -2a
Combine like terms: 2a + -2a = 0
2 + 3a = 8 + 0
2 + 3a = 8
Add '-2' to each side of the equation.
2 + -2 + 3a = 8 + -2
Combine like terms: 2 + -2 = 0
0 + 3a = 8 + -2
3a = 8 + -2
Combine like terms: 8 + -2 = 6
3a = 6
Divide each side by '3'.
a = 2
Simplifying
a = 2
