Answer:
l = (3x+5)
Step-by-step explanation:
Given that,
The area of a room, [tex]A=3x^2-x-10[/tex]
The width of the room, [tex]b=(x-2)[/tex]
We need to find the length of the room.
The area of the room is given by :
A = lb
[tex]l=\dfrac{A}{b}\\\\l=\dfrac{3x^2-x-10}{x-2}\\\\l=\dfrac{(x-2)(3x+5)}{x-2}\\\\l=(3x+5)[/tex]
So, the length of the room is equal to (3x+5).

The base of a rectangular prism is 5 meters long and 4 meters wide. The prism is 6 meters high. A rectangular pyramid has the same length, width, and height as the prism. What is the ratio of the volume of the rectangular pyramid to the rectangular prism?
Volume of prism: 5 x 4 x 6 = 120 cubic meters
Volume of pyramid: 5x4 x 6/3 = 40 cubic meters
Ratio: 40/120 = 1/3
This is a pic of my question..
Answer:
The answer is c
Step-by-step explanation:
5x+3y=19
multiply x 2: 10x+6y=38
2x-4y=-8
multiply by -5: -10x+20y=40
now you can add the two equations:
10x+6y=38
-10x+20y=40
add equations 0x+26y=78
Y=3

Un inversionista coloca 1.000.000 en un banco durante un año a una tasa de interés del 16% capitalizable mensualmente. ¿Cual es la tasa efectiva?
Answer:
Tasa efectiva anual= 0.1722= 17.22%
Step-by-step explanation:
Dada la siguiente información:
Tasa de interes anual= 16% capitalizable mensualmente
Primero, debemos calcular la tasa nominal mensual:
Tasa mensual= 0.16 / 12= 0.01333
Ahora, usando la siguiente formula, la tasa efectiva anual:
Tasa efectiva anual= (1 + i)^n - 1
Tasa efectiva anual= (1.01333^12) - 1
Tasa efectiva anual= 0.1722= 17.22%
please describe the difference between the slope and the y-intercept. Please also describe how we can use the slope and y-intercept to graph.
Answer:
The slope is basically the rate of change in which it describes how steep the line is. The y-intercept is a point in the graph in which a point crosses the y axis.
The slope and the y-intercept is connected with the formula y=mx+b, where b is the y intercept and mx is the slope. With this equation, you can graph by first putting your y-intercept (b) in the graph, remember that the y-intercept has x as 0, for example (0,4) or (0,12). After that, all you have to do to complete the line is to use the slope by plugging the x to the slope and adding the y-intercept.
Now you might have a little idea of what is the slope and y-intercept, and might still be confused on certain things, so ill give an example.
ex) you are given the formula y=2x+4 and you are asked to graph it
step 1) you take the b, which is 4 and put it in the graph, knowing the the point is (0,4) because b is the y-intercept, which means that x=0.
step 2) take a random x point on the xaxis and plug it in the formula, then you add the b (4), lets say x=2
so it will become 2(2) +4 = 6, so when x=2, y is 6.
Now you have found 2 points, (0,4) and (2,6), all you have to do is plug it in the graph.
The graph is drawn below.

How many 4-digit odd numbers can you make using the digits 1 to 7 if the numbers must be less than 6000? No digits are repeated.
Answer:
Step-by-step explanation:he first digit must be a 6, 7, or 8, because the number has to be bigger than 6,000.
The last digit must be a 1, 3, 5, or 7, because the number has to be odd.
So if the first digit is 6 or 8, there are 4 odd-number options for the last digit. If the first digit is a 7, then there are only 3 options for the last digit, as 7 can’t be used twice.
The other two digits can be anything that’s not already used. So for each first-and-last combination of digits mentioned above, there will be six options available for one of the middle digits, and then for each of those 3-digit combinations, five options will be available for the final remaining digit.
At this point, we have everything we need to express this as an equation:
x = (2 x 4 + 1 x 3) x 6 x 5
And then we can simplify and solve:
x = (8 + 3) x 30
x = 11 x 30
x = 330

It is recommended that one fire extinguisher be available for every 4,520 square feet in a building. Write and solve an equation to determine x, the number of fire extinguishers needed for a building that has 88,140 square feet.
Answer:
There are 19.5 extinguishers needed.
Step-by-step explanation:
Given that,
One fire extinguisher be available for every 4,520 square feet in a building.
We need to find the value of x if the number of fire extinguishers needed for a building that has 88,140 square feet.
x = (Area of building)/(Area of one fire extinguisher)
So,
[tex]x=\dfrac{88140}{4520}\\\\x=19.5[/tex]
So, there are 19.5 extinguishers needed.
Determine if (-11, -284 ) is a solution to the given equation: y = 14x - 129 ?
Answer:
No, it is not a solution of the equation.
Step-by-step explanation:
x=-11, y=-284
14 · (-11)-129=-283
-283≠-284

Answer:
x = 20
Step-by-step explanation:
In parallelograms opposite angles are congruent and angles that are on the same line are supplementary
This means that ∠TUR and ∠URS are supplementary angles
Supplementary angles have a sum of 180°
That being said we can find the missing angle ( ∠ URS ) by subtracting the measure of the given angle ( ∠TUR which has a measure of 160° ) from 180
so ∠URS = 180 - ∠TUR ( 160 )
180 - 160 = 20
Hence, ∠URS = 20°
