Answer:
a) 120
b) 2 globos blancos por grupo
3 globos celestes por grupo
Step-by-step explanation:
Resolvemos usando el máximo factor común
a) ¿Cuántos grupos puede formar como máximo?
Los factores de 240 son: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
Los factores de 360 son: 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
Entonces el máximo común denominador es 120.
b) ¿Cuántos globos de cada color tendrá cada grupo?
Para cada grupo,
Por los globos blancos
= 240/120 = 2 globos blancos por grupo
Por el celeste
= 360/120 = 3 globos celestes por grupo
A major car dealership has several stores in a big city. The owner wants to determine if there is a difference in the proportion of SUVs that are sold at stores A and B. The owner gathers the sales records for each store from the past year. A random sample of 55 receipts from store A shows that 30 of the sales were for SUVs. Another random sample of 60 receipts from store B shows that 42 of the sales were for SUVs. Assuming conditions for inference are met, what is the 99% confidence interval for the difference in proportions of sales that are SUVs
Answer:
confidence interval = ( -0.38 , 0.08 )
Step-by-step explanation:
Given data :
n1 = 55 , n2 = 60 ,
Let P1 ( proportion of SUV sales at store A ) = 30 / 55 = 0.55
P2 ( sample proportion of SUV sales at store B ) = 42/60 = 0.70
The Z-value at 99% confidence Interval = 2.58
Determine the 99% confidence interval for difference in proportion
applying the formula below
( P1 - P2 ) ± Z ( [tex]\sqrt{p1( 1-p1)/n1 + p2(1-p2)/n2}[/tex]
Input values above into equation
confidence interval = ( -0.38 , 0.08 )

The volume of a cube is 64 cubic meters. What is the surface area of the cube, in square meters?
Answer:
96 square meters
Step-by-step explanation:
Figuring out the side length of a cube from its volume is fairly simple. Using the cubic root we are able to deduce that the side length is 4 meters.
We then find the area of one face which is 4 * 4 = 16 square meters.
We must then multiply this by the amount of sides on our cube which is 6.
16 * 6 = 96 square meters.

16) Jenna is responsible for changing the broken light bulb in a streetlamp. The streetlamp is 14 feet high. Jenna places the base of her ladder 3 feet from the base of the streetlamp. Jenna can extend the ladder from 10 feet to 14 feet. How long must her ladder be to reach the top of the streetlamp? Will her ladder work?
Use the Pythagorean theorem:
Height is 14, base is 3, so we can calculate the length required.
Length = sqrt(14^2 + 3^2)
Length = sqrt( 196 + 9)
Length = sqrt(205)
Length = 14.32 feet.
The ladder needs to be 14.32 feet. The longest her ladder can be is 14 feet so her ladder won’t work.
Answer:
14.32 is ur awnser

Find the value of x and y of the equilateral triangle
Answer:
x = 12
y = 30
Step-by-step explanation:
We know:
All sides of equilateral triangle are equal:
= > 3 x + 8 = 4 x - 4
= > 8 + 4 = 4 x - 3 x
= > x = 12
Also, we know all angles of equilateral triangle is 60. And their sum is 180.
= > 2 y = 60
= > y = 30
Hence we get required answer!
50 decreased by ??? is 40
options are
60% 80%
19% 40%
Answer:
19%
Step-by-step explanation:
40/50 = x/100
solve for x
x is equal to 20%
but out of the answer choices it's 19%.
Answer: 19%
Step-by-step explanation:
50, percentage decreased by 60% (percent) of its value = 20
50, percentage decreased by 80% (percent) of its value = 10
50, percentage decreased by 19% (percent) of its value = 40.5
50, percentage decreased by 40% (percent) of its value = 30
Hence, the answer is 19%
CAN SOMEONE HELP LIKE RIGHT NOW!!!!!
Answer:
30 + 25 + (4x + 25) = 180
55 + (4x + 25) = 180
-55 -55
4x + 25 = 125
-25 -25
4x = 100
Divide by 4 on both sides
X = 25
Now we just replace the x with 25
4 x 25 = 100, 100 + 25 = 125 degrees is the missing angle of y
Find the missing side of this right triangle.

let f(x) = 1/x-3 and g(x) = the square root of x+5. What is the domain of (f o g) (x)
Answer:
the second one
Step-by-step explanation:
Option B is correct. the required domain of the function will be expressed as [-5, 3) U (3, ∞)
The domain of a function is the input function for which a function exists.
Given the functions
f(x) = 1/x-3
g(x) = √x+5
Get the composite function (f o g) (x)
(f o g) (x) = f(g(x))
f(g(x)) = f( √x+5)
[tex]f(g(x)) =\frac{1}{\sqrt{x+5}-3 }[/tex]
According to the function gotten, we can see that the domain of the fucntion will exist for all values of x except at x = 4. The function tends to infinity at x = 4. Hence the required domain of the function will be expressed as [-5, 3) U (3, ∞)

In order to ensure that the roof consists of right angles, an architect measures the diagonal to create a triangle. If the dimensions of the
triangle are 9.5 feet, 16 feet, and 18.5 feet, is the triangle a right triangle?
Answer:I have a question
Step-by-step explanation:
About that question is it a right triangle or no
The triangles with side lengths 9.5 feet , 16 feet and 18.5 feet is an acute triangle
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , the height of the triangle is AB = 16 feet
The base of the triangle is BC = 9.5 feet
The hypotenuse of the triangle is AC = 18.5 feet
And , for a triangle , if a² + b² > c² , it is an acute triangle
Substituting the values in the equation , we get
( 9.5 )² + ( 16 )² > ( 18.5 )²
90.25 + 256 > 342.25
346.25 > 342.25
Hence , the triangle is an acute triangle

The floor of a rectangular cage has a length 4 feet greater than its width, w. James
will increase both dimensions of the floor by 2 feet. Which equation represents the
new area, N, of the floor of the cage?
Answer:
x² + 8x + 12
Step-by-step explanation:
Area of a rectangle = length × width
Original dimensions:
Width = x
Length = x + 4
James will increase both dimensions of the floor by 2 feet
New dimensions:
Width = x + 2
Length = x + 4 + 2
= x + 6
Area of the new rectangle = length × width
= (x + 2) × (x + 6)
= x² + 6x + 2x + 12
= x² + 8x + 12
Equation which represents the
new area, N, of the floor of the cage = x² + 8x + 12
