Tenemos 2 garrafas una al 20% y otra al 30%. Cual es su capacidad de las garrafas si tenemos 12 litros de agua
Answer:
Cada garrafa tiene una capacidad de 24 litros.
Step-by-step explanation:
Tenemos dos garrafas, definamos V como el volumen que cada garrafa tiene.
Sabemos que una de las garrafas tiene el 20%, entonces el volumen de agua que tiene esta garrafa es:
(20%/100%)*V
Y la otra garrafa tiene el 30%, entonces esta garrafa tiene:
(30%/100%)*V
El volumen total de agua es la suma de esos dos volúmenes, que nos da:
(20%/100%)*V + (30%/100%)*V
Y sabemos que tenemos 12 L de agua, entonces podemos escribir la ecuación:
12 L = (20%/100%)*V + (30%/100%)*V
Ahora podemos resolver esto para V.
12L = 0.2*V + 0.3*V
12L = 0.5*V
12L/0.5 = V
24L = V
Cada garrafa tiene una capacidad de 24 litros.
What is the surface area of the cylinder shown? Use 3.14 for pie. 4cm for the Radius, and 9cm for the height.
==============================================
Work Shown:
SA = 2*pi*r^2 + 2*pi*r*h
SA = 2*3.14*(4)^2 + 2*3.14*4*9
SA = 326.56
Notes:
The answer is approximate. Use more decimal digits of pi to get a more accurate answer (though it will never be exact unless you leave it in terms of pi).The portion 2pi*r^2 is the fact we have two circular bases with area of pi*r^2 each.The portion 2*pi*r*h is the lateral area, or the area around the curved side. If you unfold this portion, as you would maybe a label on a soup can, it has base of 2*pi*r and height h. The base 2pi*r is the circumference of the circle of radius r.Answer:
[tex]326.56cm {}^{2} [/tex]
Which graph is correct?
Let's first take a look at our x here. --- (x + 2)^2
Because we are adding a two to our x, this means that we are shifting our graph 2 to the left. Remember that with functions, it's always the opposite!
There is nothing attached to the y, so we are not moving our function up or down.
And then the radius of our circle. Remember that the equation requires us to square this value (... = r^2), so we need to take the square root of 4. The square root of 4 is 2.
With this information, let's now look at our options.
Option A - INCORRECT, the radius is too large
Option B - INCORRECT, this was shifted 2 units to the right
Option C - INCORRECT, the radius is too large
Option D - CORRECT, the radius is 2 and the circle was shifted 2 units to the left
Hope this helps!! :)
Answer:
D
Step-by-step explanation:
The equation for a circle is
(x-h)^2 + (y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x+2)^2 + (y)^2 = 4
Rewritng
(x- -2)^2 + (y-0)^2 = 2^2
The center is at ( -2,0) and the radius is 2
C and D are the only circles with a center at (-2,0)
B,D are the only circles with radius 2
I could use some help please! please
Answer:
The integers could be 21 and 22
or -22 and -21
Step-by-step explanation:
If two integers are consecutive, then it means that their difference is just 1
if we have the initial value as x , then the other value could be x-1 or x + 1
let us go with x-1
So the product here is;
x(x-1) = 462
x^2-x = 462
x^2 -x -462 = 0
x^2 -22x + 21x - 462 = 0
x(x-22) + 21(x-22) = 0
(x + 21)(x-22) = 0
x = -21 or x = 22
If x = -21
x -1 = -21-1 = -22
if x = 22
x -1 = 22-1 = 21

Which of the following expressions are equivalent?
1. 5(a + 3)
2. 5a + 15
3. 3(2a + 5)
Answer:
1 and 2 are equivalent
For 1 , use distributive property. Distribute 5 to a and 3. 5 x a = 5a, and 5 x 3 = 15. Therefore, 5a + 15. This is why 1 is equivalent to number 2.
Jaxon is traveling from Portland, Oregon to Denver, CO. If he were traveling by car, he would drive 1000 miles east and 575 miles south. What distance, to the nearest tenth of a mile, would he travel if he took a direct flight from Portland to Denver?
1153.5 miles
1575 miles
425 miles
818.2 miles
Answer:
1153.5 miles (first answer choice)
Step-by-step explanation:
'1000 miles east' is the change in x ('the run'), and '575 miles south' is the change in x (the 'rise'). Since these two vectors form a right angle, we can immediately apply the Pythagorean Theorem without worrying about signs:
d = √(1000² + 575²) = 1153.5 miles (first answer choice)
Evaluate the function

In triangle HIJ, N is the centroid. If HK = 10, find KI.
Given:
In triangle HIJ, N is the centroid and [tex]HK=10[/tex].
To find:
The value of KI.
Solution:
In a triangle, the centroid of the triangle is the intersection of its medians.
Median of a triangle from a vertex divides the opposite side into two equal parts.
It is given that, N is the centroid. It means JK, HL and IM are the medians of the triangle HIJ.
Since JK is a median of the triangle HIJ, therefore it divides the opposite side IH into two equal parts.
[tex]KI=HK[/tex]
[tex]KI=10[/tex]
Therefore, the value of KI is 10 units.
Find the volume of the sphere. Round your answer to the nearest tenth.
Use 3.14 for a.
A sphere has a diameter of 4.4 centimeters.
The volume of the sphere is about
cm^3 just
Answer:
Volume of sphere = 44.57 cm³
Step-by-step explanation:
Given:
Diameter of sphere = 4.4 centimeter
Value of π = 3.14
Find:
Volume of sphere
Computation:
Radius of sphere = Diameter of sphere / 2
Radius of sphere = 4.4 / 2
Radius of sphere = 2.2 centimeter
Volume of sphere = [4/3][π][r³]
Volume of sphere = [4/3][3.14][2.2³]
Volume of sphere = [4/3][3.14][10.648]
Volume of sphere = [1.333][3.14][10.648]
Volume of sphere = 44.568
Volume of sphere = 44.57 cm³

Your cousin Pablo gets his haircut, and it costs $12.00. What will he spend in total on his haircut if he includes a 12% tip?
Answer:
The tip would be $1.44, so the total would be $13.44
Step-by-step explanation:
To find the tip you take the bill ($12), and multiply it by the percent of tip given (12%), but it has to be in decimal form. 12% in decimal form is .12. 12 times .12 is 1.44. Add $12 to that to get $13.44.
Answer:
Step-by-step explanation:
You could do this a couple of ways. The first and easiest is to change 12% to a decimal. 12% = 12/100 = 0.12
Add this onto 1.
1 + 0.12 = 1.12
Multiply this number by
12*1.12 = 12(1 +0.12) Remove the brackets
12*1 + 1.44
Haircut + tip = 13.44
Of course, it would be much shorter to do it 12*1.12 = 13.44
Two trucks leave a warehouse at the same time, traveling in opposite directions. The rate of the faster truck exceeds that of the slower truck by miles per hour. After hours, they are miles apart. What are the rates of the trucks? Use the table below to organize your work
Answer:
Speed of the slower truck = 57.5 miles/hour
Speed of the faster truck = 62.5 miles/hour
Step-by-step explanation:
Using missing information;
Assume;
Speed of the slower truck = a
Speed of the faster truck = a + 5
Distance traveled by the slower truck = d
Distance traveled by the faster truck = 600 - d
So,
a(5) = d ........ Eq1
(a+5)(5) = 600 - d
5a + 25 = 600 - d
So,
5a + 25 = 600 - 5a
10a = 575
a = 57.5
Speed of the slower truck = 57.5 miles/hour
Speed of the faster truck = a + 5
Speed of the faster truck = 57.5 + 5
Speed of the faster truck = 62.5 miles/hour

Quandrilateral ABCD is inscribed in a circle. What is the measure of angle A? A=(2x-40)B 116 C D=x what is the measure of angle A
Answer:
angle A = 88°
Step-by-step explanation:
Given: inscribed quadrilateral ABCD
(recall that inscribed quadrilaterals have opposite angles supplementary.
A=2x-40
B=116
D=x
From inscribed quadrilateral,
B+D=180 => 116+x = 180 => x=64
A=(2x-40) = 2*64-40 = 88°
(C = 180-88 = 92°)

The width of a rectangle measures (3s+t) centimeters,and it’s length measures (3s-9t) centimeters. Which expression represents the perimeter,in centimeters of the rectangle ?
Answer:
12s - 16t
Step-by-step explanation:
2(3s + t) + 2(3s - 9t)
6s + 2t + 6s - 18t
12s + 2t - 18t
12s - 16t
Answer:Perimeter of the rectangle =(12s -16t)centimeters.
Step-by-step explanation:
The perimeter of a rectangle is given as 2(l+w)
Given that width of the rectangle=(3s+t)centimeters. and
Length of the rectangle=(3s-9t)centimeters.
Solving we have
Perimeter= 2(l+w)
Perimeter=2(3s+t +3s-9t)
Perimeter=2(3s+3s -9t+t)
Perimeter=2(6s-8t)
Perimeter=(12s -16t)centimeters.

Answer:
tanθ = [tex]\frac{15}{8}[/tex]
Step-by-step explanation:
let the unknown side be x , then
Using Pythagoras' identity in the right triangle
x² + 5² = 17²
x² + 25 = 289 ( subtract 25 from both sides )
x² = 225 ( take the square root of both sides )
x = [tex]\sqrt{225}[/tex] = 15
Then
tanθ = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{15}{8}[/tex]
