Ms. Jacobsen is tilling her basement floor. The floor is in the shape of a rectangle with a length of 240 inches and a width of 180 inches. Ms. Jacobson uses tiles that are 1 square foot in size. How many tiles does Ms.Jacobsen need to cover her basement floor?
Answer:
Total number of tile used = 300
Step-by-step explanation:
Given:
Length of floor = 240 inches = 240 / 12 = 20 ft
Width of floor = 180 inches = 180 / 12 = 15 ft
Size of each tile = 1 square foot
Find:
Total number of tile used
Computation:
Area of floor = 20 x 15
Area of floor = 300 square foot
Total number of tile used = Area of floor / Size of each tile
Total number of tile used = 300 / 1
Total number of tile used = 300

The following table provides information about the median income in four states in
2016. Virginia had an index of 127.2 that year. What was the median income in Virginia?
NEED HELP ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
PLEASE SHOW STEP BY STEP EXPLANATION!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
$68,213
Step-by-step explanation:
The median is the middle value number.
So you need median for Virginia.
First lets see how index and income are connected.
To do this divide the income by the index to see if you have a constant value you can use.
535.434783 = Arkansas
535.381944 = Alabama
535.58 = Arizona
535.669236 = Alaska
535 is constant in all of these.
Let's multiply the index by 535.
127.2*535 =68212.5
For median income, you need a whole number so lets round up.
68213
So Virginia would have a median income rate of $68,213

At the State Park Zoo, there are 35 snakes in the reptile exhibit. There are 7 times as many snakes as iguanas in the reptile exhibit. How many iguanas are in the reptile exhibit?
Answer:
There are 245 Iguanas in the reptile exhibit
Step-by-step explanation:
There are 35 snakes in the reptile exhibit.
We are also given some information about the number of iguanas in the reptile exhibit. According to the problem, there are 7 times as many snakes as iguanas in the reptile exhibit.
This means that to get the number of Iguanas in the reptile exhibit, we simply multiply the number of snakes by 7.
Iguanas = snakes X 7
Iguanas = 35 X 7 =245 Iguanas
Therefore, there are 245 Iguanas in the reptile exhibit

Jocelyn owns a food truck that sells tacos and burritos. She only has enough supplies to make 150 tacos or burritos. She sells each taco for $4 and each burrito for $6.50. Jocelyn must sell at least $780 worth of tacos and burritos each day. If xx represents the number of tacos sold and yy represents the number of burritos sold, write and solve a system of inequalities graphically and determine one possible solution.
Answer:
We know that:
Price of a taco = $4
Price of a burrito = $6.50
x = number of tacos sold
y = number of burritos sold.
We must have that:
x + y ≤ 150 (Because she only has supplies to make 150 tacos or burritos, but she can sell less than that)
And also we know that she must sell at least $780, then:
x*$4 + y*$6.50 ≥ $780
Now we found the system of inequalities:
x + y ≤ 150
x*$4 + y*$6.50 ≥ $780
To solve it graphically, we just need to find each one of the region solutions for each equation, and the intersection of these regions will be the solution for the system.
To graph them may be easier to write them as lines, you can do it as follows:
y ≤ 150 - x
y ≥ ($780 - x*$4)/$6.50
in the first equation, we will shade the area below the line, and in the second equation, we will shade the area above the line.
You can see the image below.
Where the accepted solutions are the ones in the darker part, and we only restrict this to positive values of x (because of how we defined the variable x)
Then looking at the image, we can see that one solution can be the point
x = 20, y = 120

1. 2x+5(6x-9)=179
2. -40=6x-5(-4x-18)
solve for X
Answer:
1. x = 7
2. x = -5
Step-by-step explanation:
1. Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation: 2*x+5*(6*x-9)-(179)=0
Pull out like factors 6x - 9 = 3 • (2x - 3)
(2x + 15 • (2x - 3)) - 179 = 0
Pull out like factors: 32x - 224 = 32 • (x - 7)
Solve: x-7 = 0
Add 7 to both sides of the equation = 7
2. Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation: -40-(6*x-5*(-4*x-18))=0
Pull out like factors: -4x - 18 = -2 • (2x + 9)
-40 - (6x - -10 • (2x + 9)) = 0
Pull out like factors: -26x - 130 = -26 • (x + 5)
-26 • (x + 5) = 0
Solve: x+5 = 0
Subtract 5 from both sides of the equation: x = -5

What is the result when x^3-8x^2+19x-14x 3 −8x 2 +19x−14 is divided by x-2x−2? If there is a remainder, express the result in the form q(x)+\frac{r(x)}{b(x)}q(x)+ b(x) r(x) .
Answer:
The result when x^3-8x^2+19x-14 is divided by x^2-2x−2 is
[tex]x-6 +\frac{9x -26}{x^{2} -2x-2}[/tex] .
Step-by-step explanation:
Seems the divisor in the question is x^2-2x−2. If so, the solution to the division is shown using the long division method in the attachment below.
The result is
[tex]\frac{x^{3}-8x^{2} +19x -14}{x^{2} -2x-2} = x-6 +\frac{9x -26}{x^{2} -2x-2}[/tex]
is y=5 a linear function.
Answer:
No, y=5 is NOT a linear function.
Step-by-step explanation:
In order for a linear function to be true, it need to include a slope-intercept. For example, a commonly used equation, y = mx+b y = m x + b, is an example of a linear function, since it meets both the variables of m and b and criteria of x and y. In this case, when drawing out y=5 on a graph, marking it down reveals no slope.
I hope this helped to answer your question.
We now know that y = 5 is not a linear function as it cannot be written as y = MX + b.
What are linear functions?The term "linear function" in mathematics applies to two different but related ideas: A polynomial function of degree zero or one that has a straight line as its graph is referred to as a linear function in calculus and related fields. The formula y = MX + b can be used to represent any linear function, where m denotes the slope and b is the y-intercept (slope-intercept form). The alternative formula for a linear function is y - y₀ = m(x - x₀), where m denotes the slope and (x₀, y₀) the line's origin (point-slope form).As, in the description it is cleary said that linear functions can be represented in y = MX + b form, and y = 5 cannot be represented in the same form.
Therefore, y = 5 is not a linear function as it cannot be written as y = MX + b.

Negative 1.5 (4 minus r) = negative 12
Answer:
r = - 4
Step-by-step explanation:
Given
- 1.5(4 - r) = - 12 ( divide both sides by - 1.5 )
4 - r = 8 ( subtract 4 from both sides )
- r = 4 ( multiply both sides by - 1 )
r = - 4
Answer:
12
Step-by-step explanation:
1.5(4-r) = -12
To solve, first multiply 4-r by 1.5. When you do this, you can then simplify the expression and write it as 6-1.5r=-12.
With the simplified expression, you can solve for r.
Subtract 6 from both sides then divide by -1.5.
-1.5r=-18
r=12

Answer:

Step-by-step explanation:
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression. 21x+6=300 X=14, 21x14=294+6=300.

In a painting, The Great Pyramid of Giza is 45 centimeters tall.
If the pyramid is actually 146.5 meters tall, find the scale.
Answer:
The scale is: 1 cm = 3.26 meter
Step-by-step explanation:
Given
Height of Pyramid in Painting = [tex]H_p = 45 cm[/tex]
Actual Height of Pyramid = [tex]H_a = 146.5m[/tex]
In order to find the scale, we can find the ratio between actual height and height in painting.
The ratio can be found by dividing the actual height by height in painting
[tex]Scale = \frac{H_a}{H_p}\\= \frac{146.5}{45}\\=3.25555 m/cm[/tex]
Rounding off to nearest hundredth
= 3.26
This means that the scale is:
1 cm = 3.26 meter
