Tenemos 2000 baldosascon las que nos proponrmos embaldosar dos habitaciones.Para la 1ª gastamos 3/5 de ellas,y con la 2ª,3/4de las que qudaron.¿Cuántas utilizamos para cada habitación y cuántas sobraron?
Answer:
En la primera habitación son usadas 1200 baldosas.
En la segunda habitación son usadas 600 baldosas.
Sobraron 200 baldosas.
Step-by-step explanation:
Tienes 2000 baldosas, con las que se propone embaldosar dos habitaciones.
Para la primera habitación se han gastado [tex]\frac{3}{5}[/tex] de las baldosas. Esto se expresa como:
[tex]\frac{3}{5}*2000[/tex]
Para multiplicar una fracción por un número entero, el número entero n se puede escribir como la fracción [tex]\frac{n}{1}[/tex]. Luego se multiplica los numeradores y denominadores. En este caso:
[tex]\frac{3}{5}*2000=\frac{3}{5}*\frac{2000}{1} =\frac{3*2000}{5*1} = \frac{6000}{5}[/tex]
Para reducir la fraccion, divide 40 entre 10
[tex]\frac{6000}{5} =[/tex] 6000 ÷5= 1200
Entonces en la primera habitación son usadas 1200 baldosas. Por lo que las que quedan se calcula como:
2000 - 1200= 800 baldosas
De esta cantidad de baldosas que quedaron, [tex]\frac{3}{4}[/tex] son usadas para embaldosar la segunda habitación. Esto se expresa como:
[tex]\frac{3}{4}*800[/tex]
Resolviendo de igual manera que en el caso de la primer habitación se obtiene:
[tex]\frac{3}{4}*800=\frac{3}{4}*\frac{800}{1} =\frac{3*800}{4*1} =\frac{2400}{4}[/tex]= 2400 ÷ 4= 600
Entonces en la segunda habitación son usadas 600 baldosas. Por lo que, teniendo en cuenta que se tenían 800 baldosas que quedaron de la primera habitación, las baldosas restantes se calculan como:
800 - 600= 200 baldosas
Sobraron 200 baldosas.

The price of a 32 pack of water at heb is $2.98. The tax rate is 8% what is the final cost of the water
Answer:
The final cost of the water is $3.22.
Step-by-step explanation:
In order to find the answer, you have to add the tax to the price of the 32 pack of water by calculating 8% of the price and adding that amount to it.
2.98*8%=0.24
2.98+0.24=3.22
According to this, the answer is that the final cost of the water is $3.22.

Use 3.143.143, point, 14 for \piπpi and round your final answer to the nearest hundredth.
Answer:
3.04 units
Step-by-step explanation:
h = volume / (3.14 x r^2)
86 / (3.14 x 3^3) = 3.04 units
Rewrite as equivalent rational expressions with denominator (x+3)(x−4)(x+4)
An equivalent rational expressions with denominator (x+3), (x−4) and (x+4) is (3x²+6x-16)/(x³+3x²-16x-48).
The given denominator are (x+3), (x−4) and (x+4).
What is a rational expressions?A mathematical expression that may be rewritten to a rational fraction, an algebraic fraction such that both the numerator and the denominator are polynomials.
Here, an equivalent rational expressions is
[tex]\frac{1}{x+3}+\frac{1}{x-4} +\frac{1}{x+4}[/tex]
The LCM of denominators is (x+3)(x-4)(x+4)
= (x+3)(x²-16)
= x(x²-16)+3(x²-16)
= x³-16x+3x²-48
= x³+3x²-16x-48
Now, [tex]\frac{(x-4((x+4)+(x+3)(x+4)+(x+3)(x-4)}{x^3+3x^2-16x-48}[/tex]
= (x²-16+x²+7x+12+x²-x-12)/(x³+3x²-16x-48)
= (3x²+6x-16)/(x³+3x²-16x-48)
Hence, an equivalent rational expressions with denominator (x+3), (x−4) and (x+4) is (3x²+6x-16)/(x³+3x²-16x-48).

The same-side interior angles formed when two parallel lines cut by a transversal are 45° and x. Find x. a 45° b 90° c 135° d 180°
Answer: b
Step-by-step explanation:
Which function describes the vertical shift up 2 units and left 2 units to the original function: f(x) = ex
Answer:
g(x) = e^(x + 2) + 2
Step-by-step explanation:
First, let's describe the shifts.
Vertical shift.
For a function f(x), a vertical shift of N units is written as:
g(x) = f(x) + N
If N is positive, then the shift is upwards.
If N is negative, then the shift is downwards.
Horizontal shift.
For a function f(x), a horizontal shift of N units is written as:
g(x) = f(x - N)
If N is positive, the translation is to the right
If N is negative, the translation is to the left.
Now let's solve the question.
f(x) = e^x
First, we have a vertical shift up of 2 units, then:
g(x) = f(x) + 2
Now we have a shift to the left of 2 units:
g(x) = f(x - (-2)) + 2
g(x) = f(x + 2) + 2
Then:
g(x) = e^(x + 2) + 2

When rolling a die, determine the probability of rolling a number greater than 4.
a. Which outcome or outcomes make up the event of rolling a number greater than 4?
Answer:
The probability that the result of one die roll is greater than 4 is the number of events in set A divided by the total number of possible outcomes (the size of the sample space S) and so the probability of getting a number greater than 4 on one die roll is 2/6 which reduces to 1/3 .
Step-by-step explanation:
Assuming you mean “greater”, rather than “greater than or equal to”, the “successful” rolls are 5 and 6. That’s two out of six choices, so the probability is 2/6 or 1/3.
It gets more interesting when you want the total of several dice to be above a certain number, or to get that number on M of N dice rolls.
But the two basic probability formulas work - 1) add up all possible successful results and all possible results, then divide the number of successes into the total. 2) Multiply all the failure probabilities together, then subtract the result from 1 (100%) to get the success probability. With these two rules, you can solve most simple probability problems.
Playing D&D, and want to know the chance of scoring a 17 or 18 total when rolling 3 dice? You can only get an 18 one way - 6 6 6. You can get a 17 three ways - 6 6 5, 6 5 6, or 5 6 6. So that’s 4 chances out of 6 x 6 x 6 possibilities, which is 216. That’s about 1.85%. With quite a bit more work, you can discover the chance of getting a 17 or better when rolling 4 dice and adding the 3 highest.

work out the height of a triangle with base b= 7.7mm and area a=164.78mm2
Answer:
21.4 mm
Step-by-step explanation:
area ÷ base = height
164.78 mm^2 ÷ 7.7 mm
21.4 mm
Check:
base • height = area
7.7 mm • 21.4 mm = 164.78 mm^2
The height of the Triangle is 47.08 mm
What is a Triangle ?A triangle is a polygon with three sides , three vertices and three angles.
It is given that
Area of the Triangle = 164.78 sq. mm
Base of the Triangle = 7.7 mm
Area of the Triangle = (1/2) * base * height
164.78 = (1/2) * 7.7 * Height
Height = 164.78 * 2 /7.7
Height = 47.08 mm
Therefore the height of the Triangle is 47.08 mm

Two numbers have these properties Both numbers are greater than 8 The HCF is 8 The LCM is 80 Find the two numbers
Answer:
10 and 64.
16 and 40
Step-by-step explanation:
The product of the two numbers is equal to the product of LCM and HCF
Number 1* Number 2= LCM * HCF
Number 1* Number 2= 8*80
Number 1* Number 2= 640
Both the numbers are greater than 8. Suppose one number is 10 then the other number will be 640 ÷ 10= 64
so the two numbers will be 10 and 64.
Similalrly the two numbers can also be 16 and 40 and like wise.
Any number greater than 8 dividing 640 will give the second number also.

Answer:
A. -5√41/41Step-by-step explanation:
Let the horizontal leg = 4√41 and the hypotenuse = 41 as
cosine = adjacent leg / hypotenuse.Then the vertical leg is:
√(41² - 16*41) = √25*41 = 5√41Since the vertical leg is below the x-axis, its value is -5√41
Then we have:
