The front elevation of the cube will be either a square or a rectangle.
What is a cube?A three-dimensional object with six congruent square faces is called a cube. The cube's six square faces all have the same dimensions.
Given that, a solid shape is made from 4 cubes.
The front face of a cube is square, therefore, the front elevation of 4 cubes will be either a square or a rectangle.
Hence, the front elevation of the cube will be either a square or a rectangle.

Answer:
The slope of the line is 8.
Step-by-step explanation:
To solve this problem, we can use the formula for slope:
slope = m = (y2 - y1)/(x2 - x1)
If we substitute in two points from the table into this formula, we get:
slope = m = (11-3)/(1-0) = 8/1 = 8
Therefore, the slope of the line is 8.
We can also see this by looking at the table itself. Since both x and y are increasing together, we know that the slope should be positive. For every increase in 1 in x, y increases by 8; this confirms that the slope of the line is 8.

The Martians are trying to destroy Earth by launching an anti-matter rocket (it will be disastrous it will hit earth). In response, Earth launches 500 missiles towards the rocket. Each missile will hit the rocket with probability 0.01, independently of other missiles. What is the probability that Earth will be saved, if at least 3 missiles must hit the rocket in order to destroy it before it hits Earth
Answer:
The probability the earth is saved is [tex]P(X > 3) = 0.8753 [/tex]
Step-by-step explanation:
From the question we are told that
The number of missiles lunched by earth is n = 500
The probability that each missile will hit the rocket is p(x) = 0.01
Generally the expected number of missiles that will hit the rocket is
[tex] \lambda = n * p(x)[/tex]
[tex]\lambda = 500 * 0.01 [/tex]
[tex]\lambda = 5[/tex]
Gnerally the probability that Earth will be saved is mathematically represented as
[tex]P(X > 3) = 1 - P(X \le 2)[/tex]
=> [tex]P(X > 3) = 1 - P( X = 0 ) + P(X =1 ) + P( X = 2) [/tex]
Gnerally the probability distribution function of a Poisson distribution is
[tex]P(K) = \frac{e^{- \lambda t } * (\lambda * t)^k}{k!}[/tex]
Here t = 1
Hence
[tex]P( X = 0 ) = \frac{e^{-5} * 5^0 }{0!}[/tex]
[tex]P(X =1 ) =\frac{e^{-5} * 5^1 }{1!}[/tex]
[tex]P( X = 2) = \frac{e^{-5} * 5^2 }{2!}[/tex]
[tex]P(X > 3) = 1 - [ \frac{e^{-5} * 5^0 }{0!} + \frac{e^{-5} * 5^1 }{1!} + \frac{e^{-5} * 5^2 }{2!}][/tex]
[tex]P(X > 3)= 1 - [ \frac{0.00673 }{1} + \frac{0.033689}{1} + \frac{0.168449 }{2}][/tex]
[tex]P(X > 3) = 0.8753 [/tex]

Karen used a birthday check her mother gave her to start a savings account. She plans to save $25 per
month as well. After 8 months, Karen has $250. Write and solve a linear equation to find the original check
amount from Karen's mother.
Answer:
Explanation:
Lets just say the amount her mom gave her is c
and the months is a
the equation would be
c + 25a = 250
we can plug in 8 for a, cause we know its been 8 months,
c + 25(8)= 250
then do the parentheses
c + 200 = 250
subtract the 200 to isolate the variable c
c = 50
then you get c = 50,
Karen's mom gave her a check for $50.
(why karen btw. i would never give $50 to a karen)
The linear equation to calculate the amount from Karen's mother is
A + 25x = 250
where A is the amount and x is the number of months
The amount from Karen's mother is $ 50
What is an 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.
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.
Given data ,
Let the amount given to Karen by her mother be = A
Let the total number of months be = x
The value of x is = 8 months
The total amount Karen has after 8 months = $ 250
The amount Karen saves per month = $ 25
Now , the equation will be
Total amount Karen has after 8 months = amount given to Karen by her mother + ( amount Karen saves per month x total number of months )
Substituting the values in the equation , we get
250 = A + 25x
On simplifying the equation , we get
A + 25x = 250
when x = 8
A + 25 ( 8 ) = 250
A + 200 = 250
Subtracting 200 on both sides of the equation , we get
A = $ 50
Therefore , the value of A is $ 50
Hence , The linear equation to calculate the amount from Karen's mother is A + 25x = 250
where A is the amount and x is the number of months
The amount from Karen's mother is $ 50

The length of a rectangle is 11 feet more than the width. If the perimeter is 46 feet, then what is the length of the rectangle, in feet?
Answer:
Hi there!
Your answer is:
The length is 17
Step-by-step explanation:
L= 11+w
P=46
perimeter formula:
W+W+L+L = P
W+W+(11+w)+(11+w) = P
First solve for W
4W+22 = 46
-22
4w=24
/4
w=6
Now plug in W for the L formula
l=11+w
L= 11+ 6
L=17

I have 3 times as many nickels as quarters. How many quarters do I have if I have
a total of $2.40
Answer:
18 Nickels, 6 Quarters
Step-by-step explanation:
For this problem, let's build a system of equations to find the number of nickels and dimes you have. Let N represent the number of nickels and Q represent the number of quarters you have.
The first equation, you have 3 times as many nickels as quarters:
N = 3Q
The second equation, you have a total of $2.40. Given we know nickels are $0.05 and quarters are $0.25:
0.05N + 0.25Q = 2.40
Now, let's use the two equations to find the number nickels and quarters you have.
N = 3Q
0.05N + 0.25Q = 2.40
0.05(3Q) + 0.25Q = 2.40
0.15Q + 0.25Q = 2.40
0.4Q = 2.40
Q = 6
Now, let's plug the value back into the equation:
N = 3Q
N = 3(6)
N = 18
And we can verify these values with the second equation:
0.05N + 0.25Q = 2.40
0.05(18) + 0.25(6) ?= 2.40
0.90 + 1.50 ?= 2.40
2.40 == 2.40
Therefore, we have found and verified the amount of Nickels and Quarters you have.
Cheers.

To transmit information on the internet, large files are broken into packets of smaller sizes. Each packet has 1,500 bytes of information. An equation relating packets of information is given by b = 1500p where p represents the number of packets and b represents the number of bytes of information.
a. How many packets would be needed to transmit 30,000 bytes of information?
Answer:
20
Step-by-step explanation:
If you have 1,500 per package and you need to find how many you will need to get 30,000 all you have to do is divide 30,000 by 1,500 and you get 20 packages. So the final equation would be 30,000=1500(20)
