Solution:
Given dimensions of the rectangular sheet
Length = 28 cm
Breadth =22 cm
If the sheet is rolled to form a cylinder then the length becomes height and breadth becomes circumference of the base of a cylinder.
So Height of the cylinder (h)= 28 cm
Circumference of the base of a cylinder

2x + 5y = 10
i need the slope and y-intercept
Answer:
Slope: [tex]-\frac{2}{5}[/tex]
Y-intercept: 2
Step-by-step explanation:
We have to isolate y;
2x + 5y = 10
5y = -2x + 10
y = [tex]\frac{-2x + 10}{5}[/tex]
y = [tex]-\frac{2}{5} x + 2[/tex]
Hope this helps!

Answer:
x = - 10
Step-by-step explanation:
Given
- [tex]\frac{4}{5}[/tex] x = 8 ( multiply both sides by 5 to clear the fraction )
- 4x = 40 ( divide both sides by - 4 )
x = - 10
Answer:
x= -1/10

Answer:
Square: x= +or - [tex]\sqrt{7}[/tex], Triangle: x= + or - [tex]\sqrt{23}[/tex]
Step-by-step explanation:
For the square
4[tex]x^{2}[/tex]=28
dvide by four:
[tex]x^{2}[/tex]=7
Take the square root of both sides
x= +or - [tex]\sqrt{7}[/tex]
For the Triangle
(1/2) (2x) (2x)=46
2[tex]x^{2}[/tex]=46
Divide by 2
[tex]x^{2}[/tex]=23
x= + or - [tex]\sqrt{23}[/tex]

what number goes into the missing space
Answer:
12
Step-by-step explanation:
mrk me brainliest plzzzzzzzzzz
Answer:
b) 12
Step-by-step explanation:
The first image shows the top 2 numbers as 5 and 2 = 5 * 2
=> 10
The Second image shows the top 2 numbers as 3 and 3 = 3 * 3
=> 9
So, the third image shows the top 2 numbers as 2 and 6 = 2 * 6
=>12
Therefore, the missing space in the third circle is b) 12

Number of offspring and weight, in pounds, of 23 randomly selected rabbits are compared. Which significance test should be used to see if number of offspring and weight have a linear relationship? Assume all test conditions are met. (4 points)
Answer:
t test for the slope of regression line
Step-by-step explanation:
Suppose a random sample is drawn from the bivariate normal population and the estimated regression equation is found Y^= a +bX , where, b , the sample estimate of β1 is normally distributed with mean β and standard deviation
σyx / √∑(x-x`)².
The test statistic has t distribution where
t= b-β/sb
where sb= Syx / √∑(x-x`)² with υ= n-2 degrees of freedom.
It is important to note that the testing of hypothesis that β= 0 is equivalent to testing the hypothesis that variable Y is independent of the variable X in the linear sense.
The test statistic then becomes t= b/ sb .
If we reject H0 : β= 0 we conclude that the two variables are linearly independent.

Find the sum of a finite geometric series.
At the beginning of every year, Molly deposits $200 in a savings account that offers an interest rate of 20%, compounded annually. The total
amount that Molly will have in her account at the end of 3 years is $
Answer:
$345.60
Step-by-step explanation:
From the above question,
P = Principal = $200
R = Interest rate = 20%
T = Time in years = 3 years
n = Number of times interest is compounded = Annually = 1
First, convert R as a percent to r as a decimal
r = R/100
r = 20/100
r = 0.2 rate per year,
Then solve the equation for A
The formula =
A = P(1 + r/n)^nt
A = 200.00(1 + 0.2/1)^(1×3)
A = 200.00(1 + 0.2)^(3)
A = $345.60
Therefore, the total amount that Molly will have in her account at the end of 3 years is $345.60
if you can, answer at least 2 question I put 10 points on it
Answer:
a) one solution(x = 9)
b) no solution
c) infinite solutions
Step-by-step explanation:
a) To solve this equation, we can add 4 on both sides in order to isolate x:
x - 4 =5
+ 4 + 4
x = 9
Since x equals 9, that counts as only one solution, as there is only one value of x that makes the equation true.
b) We start by subtracting 2x from both sides to combine the variable terms:
2x - 6 = 2x + 5
-2x -2x
-6 = 5
The statement, -6 = 5 is never true and it is not dependent on the value of x. This means there are no solutions to this equation.
c) We can start by subtracting 3x from both sides to combine the terms with x:
3x + 12 = 3x + 12
-3x -3x
12 = 12
The statement above is always true, and no matter the value of x, it will always be true. This means there are infinite solutions to the equation.

A jewelry designer sells bead necklaces in a local farmer's market. The profit P that she makes from selling x necklaces is given by P = −x2 + 35x. What is the least number of her necklaces she must sell to make a profit of $300.00?
Answer:
15
Step-by-step explanation:
Given that the profit equation from selling x necklaces is
P = −x2 + 35x.
To make a profit of $300, the profit P = 300 then
300 = -x2 + 35x
x2 - 35x + 300 = 0
solve by factorization
x2 - 15x - 20x + 300 = 0
x(x - 15) - 20(x - 15) = 0
(x - 15)(x - 20) = 0
x - 15 = 0 or x - 20 = 0
x = 15 or 20
Since 20 is higher, the least number of her necklaces she must sell to make a profit of $300.00 is 15
Mr. Garner purchased a party hall and wants to repaint it as part of the renovations. He needs to calculate the lateral surface area of the party hall so that he will know how much paint to buy. The party hall is in the shape of a rectangular prism with the dimensions shown below.
Including the doors, what is the lateral surface area of the party hall in square feet?
1,904 ft2
1,860 ft2
3,764 ft2
14,280 ft2
Answer:
The lateral surface area is: 1860 square feet
Step-by-step explanation:
Given
The missing dimension are:
See attachment for storage
[tex]L = 20[/tex] --- Length
[tex]W = 42[/tex] --- Width
[tex]H = 15[/tex] --- Height
Required
The lateral surface area
The lateral area is calculated as:
[tex]Area = 2 * H * (L + W)[/tex]
So, we have:
[tex]Area = 2 * 15 * (20 + 42)[/tex]
[tex]Area = 30 * (20 + 42)[/tex]
[tex]Area = 30 * 62[/tex]
[tex]Area = 1860[/tex]
The fourth term of an exponential sequence is 108 and the ratio is 3 . Calculate the value of the eighth term of the sequence, calculate the sum of the first five terms of the sequence.
Answer:
8th term = 8748 , Sum of 5 terms = 484
Step-by-step explanation:
Formula for nth term in an exponential sequence = a r^ (n-1)
Here : n = 4 , ratio r = 3 ; And nth ie 4th number = 108
So, a r^ (n-1) = nth item implies that → a 3 ^ (4-1) = 108
a 3^3 = 108 → 27 a = 108 → a = 108 / 27 → a = 4
8th term = a r^ (n-1) , at n = 8. So, = 4 3^(8-1) = 4 3^7 = 4 x 2187 = 8748
Sum of n terms = a [(r^n) -1 ] / [r - 1] → Sum 5 terms = 4 [ (3^5)- 1] / [3 - 1]
= 4 [ (243) - 1] / 2 ] = 2 x 242 = 484

What number is 0.01 more than 253.498?
Answer:
1/64
Step-by-step explanation:
Doing it by hand, I get that the number is 1/16 which is equal to 0.0625 and the previous one will be 1/8 which is 0.125.
In the formula given by others, if you apply the 12 to it you will get an=2(5-12)which is equal to 0.0078, less than 0.100 but not the first number.
The correct value for n is 9 that will give us 2-4=1/16
253.508 is 0.01 more than 253.498.
What is Number system?A number system is defined as a system of writing to express numbers. It is the mathematical notation for representing numbers of a given set by using digits or other symbols in a consistent manner.
It provides a unique representation of every number and represents the arithmetic and algebraic structure of the figures.
Let the number be x
so,
x=253.498+0.01
x= 253.508
