The diameter of a circular placemat is 42 centimeters. What is the approximate area of the circular placemat
[tex] area \: of \: a \: circle \: or \: circular \: object \: = \pir^{2} \\ \: [/tex]
Answer:
1386cm^2.
Step-by-step explanation:
Radius of a circle = diameter / 2
= 42cm /2
= 21cm.
Area = (3.142 *21*21)cm^2
= 1386cm^2
To convert into metres:
=1386/100
=13.86m^2
Hamilton, NY has 73465 residents, and 12 members on their Board of Trustees. The three districts of Basel, Heights, and Dagonal have the following populations: Basel: 13,244 Heights: 30, 415 Dagonal: 29,806 Determine the standard quota (to two decimal places) for the Dagonal district. 6) Gotham City is to apportion 16 seats to districts with populations as follows: North: 785 South: 1,125 East: 1,950 West: 415 Find the standard divisor What are the standard, lower, and upper quotas for the four districts?
a) The determination of the standard quota for the Dagonal district is 40.57%.
b) 1. The standard divisor is 267.19 (4,275/16).
2. The standard, lower, and upper quotas for the four districts are as follow:
North South East West
Standard quota 18.36% 26.32% 45.61% 9.71%
Lower quota 18% 26% 45% 9%
Upper quota 18% 26% 46% 10%
What is the quota method of apportionment?The quota method of apportionment is the use of the standard divisor to round off standard quotas, according to some agreed ground norms.
When the standard quota is rounded down to an integer, it gives the lower quota, and rounding up gives the upper quota.
The standard divisor is calculated as the total population divided by the total number of seats.
The standard divisor gives the average number of people represented by a Board or seat member.

A population P is initially 3000. Find an exponential model (growth or decay) for the population after t years if the population P decreases by 0.36 every 7 years. (Round your terms to three decimal places.)
The population model is an exponential decay because it decreases
The exponential model of the population is P = 3000(0.64^1/7)^t
How to determine the function?The population decreases by 0.36 every 7 years.
This means that the function is an exponential decay.
An exponential decay function is represented as:
P = a((1 - r)^1/n)^t
Where:
a represents the initial value (3000)r represents the rate (0.36)n represents the number of years the population decreases (7)P and t are the variablesSo, we have:
P = 3000((1 - 0.36)^1/7)^t
Evaluate the difference
P = 3000(0.64^1/7)^t
Hence, the exponential model of the population is P = 3000(0.64^1/7)^t

Answer:
a. y = 7.5x + 1
b. y intercept is 1, which means the puppy weighed 1 pound at birth or at 0 months old.
c. slope is 7.5 which means puppy gained 7.5 pounds a month for the first 6 months.
Step-by-step explanation:
To find slope: use rise/run formula (y2 - y1 / x2 - x1) which is,
(23.5 - 16) / (3 - 2) = 7.5
To find y intercept: Plug in y, x and b in the slope intercept formula (y=mx+b). choose any one of the pairs from the table. i chose 2 and 16. plug it in and the formula would now look like 16 = 7.5(2) + b .
solve for b
16 = 15 + b (multiply 7.5 and 2)
1 = b (subtract 15 from 16)
y intercept is 1

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have,
Josiah's head start = 10 meters from the start
Josiah's speed = 2 m/s
Chana's speed = 3 m/s
Now, the distance travelled as
D= d x s+ t
For Josiah, we have;
D = 10 + 2•t (line a)
For Chana, we have;
D = 0 + 3•t = 3•t (line b)
Thus, Josiah's distance from the starting line at a time when he is behind Chana.

Evan owns a small business selling ice-cream. He knows that in the last week 83
customers paid cash, 8 customers used a debit card, and 2 customers used a credit
card.
Based on these results, express the probability that the next customer will pay with a
debit card or a credit card as a percent to the nearest whole number.
The probability that the next customer will pay with a debit card or a credit card is 12%.
What is the probability that the next customer would pay with a debit card or a credit card?
Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability that the next customer would pay with a debit card or a credit card = (number of customers that paid with a debit card + number of customers that paid with a credit card) / total number of customers
(8 + 2)/ 83 = 0.12 = 12%

of 7 inches. Beau's water bottle has a radius of 2 inches and a height of 9 inches. Whose water bottle holds more water and how much more does it hold? Round to the nearest hundredth.
The bottle that holds more water has the larger volume
Beau's water bottle holds more water
How to determine the bottle with more water?The given parameters are:
Drew
Diameter = 3 inchesHeight = 7 inchesBeau
Radius = 2 inchesHeight = 9 inchesThe volumes of their bottles is calculated using:
V = πr^2h
So, we have:
Drew = 3.14 * (3/2)^2 * 7
Drew = 49.46
Beau = 3.14 * (2)^2 * 9
Beau = 113.04
By comparison, 113.04 is greater than 49.46

Among all rectangles that have a perimeter of 188, find the dimensions of the one whose area is largest.
the length of a rectagle is 5 in longer than its width. if the perimeter of the rectangle is 58 in, find its length and width
Answer:
Length: 17 in, Width: 12 in
Step-by-step explanation:
Let l=length and w=width
l=w+5
2(w+5)+2w=58
4w=48
w=12, l=17
Answer:
Length = 17 inchesWidth = 12 inches⠀
Step-by-step explanation:
⠀
As it is given that, the length of a rectangle is 5 in longer than its width and the perimeter of the rectangle is 58 in and we are to find the length and width of the rectangle. So,
⠀
Let us assume the width of the rectangle as x inches and therefore, the length will be (x + 5) inches .
⠀
Now, According to the Question :
⠀
[tex]{\longrightarrow \qquad { \pmb{\frak {2 ( Length + Breadth )= Perimeter_{(Rectangle)} }}}}[/tex]
⠀
[tex]{\longrightarrow \qquad { {\sf{2 ( x + 5 + x )= 58 }}}}[/tex]
⠀
[tex]{\longrightarrow \qquad { {\sf{2 ( 2x + 5 )= 58 }}}}[/tex]
⠀
[tex]{\longrightarrow \qquad { {\sf{ 4x + 10= 58 }}}}[/tex]
⠀
[tex]{\longrightarrow \qquad { {\sf{ 4x = 58 - 10}}}}[/tex]
⠀
[tex]{\longrightarrow \qquad { {\sf{ 4x = 48}}}}[/tex]
⠀
[tex]{\longrightarrow \qquad { {\sf{ x = \dfrac{48}{4} }}}}[/tex]
⠀
[tex]{\longrightarrow \qquad{ \underline{ \boxed { \pmb{\mathfrak {x = 12}} }}} }\: \: \bigstar[/tex]
⠀
Therefore,
The width of the rectangle is 12 inches .⠀
Now, We are to find the length of the rectangle:
[tex]{\longrightarrow \qquad{ { \frak{\pmb{Length = x + 5 }}}}}[/tex]
⠀
[tex]{\longrightarrow \qquad{ { \frak{\pmb{Length = 12 + 5 }}}}}[/tex]
⠀
[tex]{\longrightarrow \qquad{ { \frak{\pmb{Length = 17}}}}}[/tex]
⠀
Therefore,
The length of the rectangle is 17 inches .⠀

solve for t; 1/11=cos((2π/3)t)
Answer:
Step-by-step explanation:
Method
Take the inverse Cos of both sides. That will give you the angle on the left.
From there you can solve for t
cos-1(1/11) = cos-1 cos ((2pi/3)t)
1.4798 = 2*pi*t/3 Multiply both sides by 3/2
1.4798 * 3/2 = (2pi*t/3)*3/2
2.2196 = 2*pi*t Divide both sides by 2*pi
2.2196 / (2*pi) = t
t = .3534
This was done by setting my calculator to radians. 1.4798 is a radian measure.

A Triangle has a perimeter of 80 feet. If the three sides of the triangle are, n, 3n + 7, and 3n + 3, what is the length of each side?
Answer:
Step-by-step explanation:
Givens
Perimeter = 80 feet
side 1 = n
side 2 = 3n + 7
side 3 = 3n + 3
Formula
Side 1 + side 2 + side 3 = 80
Solution
Substitute the length for each side into the equation
n + 3n + 7 + 3n + 3 = 80
7n +10 = 80 Subtract 10 from both sides
7n + 10 - 10 = 80 - 10 Combine
7x = 70 Divide by 7
7x/7 = 70/7 Combine
x = 10
Answer
Side 1 = n = 10
Side 2 = 3n + 7 = 3*10 + 7 = 37
Side 3 = 3n + 3 = 30 + 3 = 33
