amy bought a square table for her kitchen. The area of the table’s surface is 99ft². What is the best approximate length of one side of the table?
Answers
A (area) = 2 * (L/Length) / or (L/Length)^2
A = L2
99 ft^2 = L^2
√99 ft^2 = √L^2
9.9498743710662 ft = L
So, Length (L) = 9.9498743710662 ft.
(this length value applies for 4 (4x) since it's a 4-equal side polygon shape)
Nina can ride her bike 63,360 feet in 3,400 seconds, and sophia can ride her bike 10 miles in 1 hour. What is nina’s rate in miles per hour if there are 5,280 feet in a mile? Which girl bikes faster?
Answers
Answer:
Nina's rate in MPH: 12.706 miles per hour
Nina is faster than Sophia.
Step-by-step explanation:
For this problem, we will convert feet per second into miles per hour, and then compare Nina's rate to Sophia's rate.
We are given Nina rides at 63360 feet in 3400 seconds. To convert this to miles per hour, we need to know that there are 5280 feet in 1 mile, and 3600 seconds in 1 hour. Now that we now these conversions, let's find the rate in miles per hour.
(63360 feet / 3400 seconds) * (1 mile / 5280 feet) * (3600 seconds / 1 hour) = 12.706 miles per hour.
So we know that Nina rides her bike at 12.706 miles per hour and are given that Sophia rides her bike in 10 miles in 1 hour.
With this, we can say Nina rides faster than Sophia by 2.706 miles per hour (12.706 - 10).

greg is 10 years older than his brother gabe.he is also 3 times as old as gabe.how old is gabe
Answers
Answer:
The answer is below
Step-by-step explanation:
Let us assume that the age of Greg's brother (Gabe) is x years, and let Greg's age by y years. Since Greg is 10 years older than his brother gabe, then:
y = x + 10 (1)
Also. Greg is 3 times as old as Gabe, hence:
y = 3x (2)
From equation 1 and equation 2:
y = x + 10 = 3x
Hence:
3x = x + 10
Subtracting x from both sides gives:
3x - x = x + 10 - x
2x = 10
Dividing by 2:
2x/2 = 10/2
x = 5 years
y = x + 10 = 5 + 10 = 15 years
Therefore Gabe is 5 years old and Greg is 15 years old

Which of the following represents the equation
after combining the like terms?
-8x + 23 – 22x + 9 = 182
a. 14x + 32 = 182
b. -30x + 32 = 182
c. 14x + 14 = 182
d. -30x + 14 = 182
Answers
Answer: B
Step-by-step explanation: The answer would be B because both the 8x and 22x are both negative so once you add those two together you would get -30x so that cancels out A and C. SO now you move onto 23 and 9 well both of those are positive so you would add those together and get 32 so that cancels out D and only answer left is B
The equation that represents -8x + 23 – 22x + 9 = 182 after combining the like terms is b. -30x + 32 = 182 , where x = -5.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
The given equation is,
-8x + 23 – 22x + 9 = 182
Taking alike terms together we get,
-8x – 22x + 23 + 9 = 182
Solving we get,
– 30x + 32 = 182
Subtracting 32 both the side we get,
– 30x + 32 - 32 = 182 - 32
Solving we get,
– 30x = 150
⇒ x = -5
Thus, The equation that represents -8x + 23 – 22x + 9 = 182 after combining the like terms is b. -30x + 32 = 182 where, x = -5.

Answers
Answer:
Step-by-step explanation:
The first step in solving an equation is to look at it. Identify where the variable is that you're interested in, and see what operations are being performed on that variable.
Here, the variable w has 1 added to it, and the sum is multiplied by -4. The variable is only on the left side of the equation, and is inside parentheses. Inside parentheses, the coefficient of the variable is 1.
These observations tell you that, in some order, you will need to undo the operations of multiplication and addition, and you will have to eliminate parentheses.
You also observe that the multiplication factor of the parentheses (-4) is a factor of the constant on the right side of the equation (-24). This means you have a couple of options for solving this equation:
eliminate parentheses first, using the distributive propertydivide by -4 first, to undo the multiplicationThe second method is actually faster. We'll illustrate that one first.
__
Divide both sides of the equation by -4 to undo the multiplication by -4.
-4(w +1)/(-4) = -24/(-4) . . . . . we have indicated the division we want to do
w +1 = 6 . . . . . . . . . . . . . . . . here is the result of that division
Now, we can add the opposite of +1 to eliminate the constant from the left side. As with all operations on equations, we must do the same thing to both sides. This means we add -1 to both sides of the equation:
w +1 -1 = 6 -1 . . . . . . we have indicated the addition we want to do
w = 5 . . . . . . . . . . . here is the result of that addition
The solution of the equation is ...
w = 5
__
Often, when parentheses are involved, the numbers are such that the solution method is not as simple as what we just did. In those cases, you would take the approach of eliminating parentheses first. For this equation, it looks like this:
-4(w +1) = -24 . . . . . . . given
-4w -4 = -24 . . . . . . . . use the distributive property to eliminate parentheses
We want the variable term by itself, so we need to eliminate the constant -4 that is added on the left. To do that, we add its opposite. This means we add +4 to both sides of the equation.
-4w -4 +4 = -24 +4 . . . . . . indicating the addition of +4
-4w = -20 . . . . . . . . . . . . . the result of adding +4
Here, w is multiplied by -4. We want w by itself, so we want to undo that multiplication. That means we want to divide both sides of the equation by -4.
-4w/(-4) = -20/(-4) . . . . . . indicate the division
w = 5 . . . . . . . . . . . . . . . . the result of doing the division
The solution of the equation is ...
w = 5
_____
Our basic approach is to undo the operations done to the variable, in the reverse of the order in which they are done. In that process, we observe the rules of equality: whatever operation you do to one side of the equation must also be done to the other side. (My teacher called this last rule: "keep the equal sign sacred.")
You can always use the distributive property for factoring, collecting terms, or eliminating parentheses.

Step-by-step explanation:
y=2x-6
the perpendicular to this will have the opposite reciprocal slope.
The new equation will be
y=(-1/2)x-b
--------------------------
To find the y-intercept of the equation, we should substitute the point into the equation (5,4)
y=(-1/2)x-b

4=-2.5-b
b=-6.5
------------------------------
so the equation will be y=(-1/2)x-6.5

Step-by-step explanation:
First find the volume of the original cylinder. It is given by πr²h:
π * (10.5)² * 63 ≈ 21820.717 cm³
Next find the volume of each cube. It is given by lwh:
3 * 3 * 3 = 27 cm³
Finally, divide the volume of the original cylinder by the volume of each cube to determine the number of cubes:
21820.717 / 27 ≈ 808.1747
Partial cubes are not possible, so the answer is 808.

The perimeter of a rectangle is 80 inches. The length is 4 inches longer than twice the width. What are the dimensions of the rectangle?
Answers
Answer:
length = 28 cmwidth = 12 cmStep-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
Perimeter = 80cm
The length is 4 inches longer than twice the width is written as
l = 4 + 2w
Substitute this into the formula and solve for the width
That's
80 = 2( 4 + 2w) + 2w
80 = 8 + 4w + 2w
6w = 80 - 8
6w = 72
Divide both sides by 6
w = 12 cm
Substitute w = 12 cm into l = 4 + 2w
That's
l = 4 + 2(12)
l = 4 + 24
l = 28cm
Therefore
length = 28 cm
width = 12 cm

In graphing inequalities, the first thing to do is graph the equation first irregardless of the inequality symbol. In the given problem, the equation to be graphed is f(x) = 2/9x + 3. Since it has a general form of y=mx + b, this is a linear function. Plot the graph by assigning arbitrary points of x, then you get the corresponding f(x) values. Graph the x values against the f(x) values. The blue line the attached picture will be formed.
Next, you solve the equation by finding x. Just don't mind the inequality symbol:
2/9 x + 3 > 4 5/9
2/9x > 4 5/9 - 3
2/9x > 14/9
x > 14/9 ÷ 2/9
x > 7
Hence, the value of x must be greater than 7. To show this in the graph, find the line where x=7. Create a partition using that line, then shade the rest of the portion where x is greater than 7 until infinity.

Explicação passo a passo:
Dado o seguinte:
Pagamento diário até as 18h00
Pagamento por hora trabalhada = 5,00
Em um determinado mês:
Trabalhou 25 dias: (25 * 20) = 500,00
20 horas à noite: (20 * 5) = 100,00
Ganho total = 500 + 100 = 600,00
