Luz tiene 240 globos blancos y 360 celestes y los usará para decorar un salón. Si los ubica en grupos de manera que cada uno tenga la misma cantidad de globos de cada color, a) ¿Cuántos grupos puede hacer como máximo? b) ¿Cuántos globos de cada color tendrá cada grupo?
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
The circumference of a circle is 87.92 inches. What is the circle's diameter? Use 3.14 for n.
Answer:
28
Step-by-step explanation:
circumference=diameter × π
diameter=87.92÷3.14=28
The diameter of circle will be 28 inches.
What is Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Given that;
The circumference of a circle is 87.92 inches.
Now,
We know that;
The circumference of circle = 2πr
Since, The value of π = 3.14
Substitute all the values, we get;
⇒ 87.92 = 2 × 3.14 × r
⇒ 87.92 = 6.28 r
⇒ r = 14
Thus, The diameter of circle = 2 × 14
= 28 inches

Find the area of the figure below. * 23 cm 12 cm 18 cm 15 cm
The area of the figure = area of trapezium + area of rectangle = 420 cm².
What is the Area of a Trapezium and Area of a Rectangle?Area of trapezium = 1/2(a + b)h
Area of rectangle = length × height.
The area of the figure = area of trapezium + area of rectangle
The area of the figure = 1/2(a + b)h + length × height
Plug in the values
The area of the figure = 1/2(23 + 15)6 + 23 × 12
The area of the figure = 144 + 276

Answer: The area is 390 cm
Step-by-step explanation:
All you have to do is find the area of the trapezoid and the area of the rectangle and add them together.
Area of trapezoid formula: A = 1/2 (Base 1 + Base 2)h
base 1 = 15 cm
base 2 = 23 cm
height = 6 (18-12)
so, 15 + 23 = 38
38 x 6 = 228
228 x 0.5 or 1/2 = 114
Therefore the area of the trapezoid is 114 cm
Area of rectangle formula: A = bh
base = 23
height = 12
12 x 23 = 276
Therefore the area of the rectangle is 276 cm
Now add the values together, 114 + 276 = 390
390 is the area of the figure

A certain television is advertised as a 85 inch TV if the width of the TV is 67 how tall is the TV
Answer:
Step-by-step explanation:
Apply the Pythagorean Theorem:
85^2 = 67^2 + h^2, where h is the height of the TV
Then 7225 = 4489 + h^2, or
h^2 = 2736, or h = +√2736 = 52.3 inches
The TV is 52.30 inches tall if the television is advertised as an 85-inch TV if the width of the TV is 67.
What is a right-angle triangle?It is defined as a triangle in which one angle is 90 degrees and the other two angles are acute angles. In a right-angled triangle, the name of the sides are hypotenuse, perpendicular, and base.
We have:
A certain television is advertised as a 85 inch TV
It means the diagonal length is 85 inches.
Width of the TV = 67 inches
Let's suppose the TV is x inches Tall
So from the Pythagoras theorem:
[tex]\rm 85^2 = x^2+67^2[/tex]
7225 = x² + 4489
x = 52.30 inches
Thus, the TV is 52.30 inches tall if the television is advertised as an 85-inch TV if the width of the TV is 67.

1. Point B is located at (-4, -6). Where is the location of B’ after a reflection over the y-axis?
a. (4, -6)
b. (-4, 6)
c. (-6, -4)
d. (-6, 4)
Answer:
a. (4, -6)
Step-by-step explanation:
When a reflection over the y-axis takes place, the x value will change its sign, while the y value will remain the same. Test this using a graph if needed. Recall that a reflection over the n axis will not change the value of the n coordinate.
the equation of the line that is perpendicular to the line with equation y=-2x-1 and passes through the point (1, -2) is?
Answer:
[tex]y=\frac{1}{2} x-\frac{5}{2}[/tex]
Step-by-step explanation:
Hi there!
Note that:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)Perpendicular lines always have slopes that are negative reciprocals of each other (ex. 3 and -1/3, 5/6 and -6/5, etc.)1) Determine the slope (m)
When we look at the given line, [tex]y=-2x-1[/tex], we can identify that -2 is in the place of m, the slope of the line. Because perpendicular lines are negative reciprocals of each other, we know that a line perpendicular to this would have a slope of [tex]\frac{1}{2}[/tex]. Plug this into [tex]y=mx+b[/tex]:
[tex]y=\frac{1}{2} x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=\frac{1}{2} x+b[/tex]
Plug in the given point (1,-2)
[tex]-2=\frac{1}{2}(1)+b\\-2=\frac{1}{2}+b[/tex]
Subtract 1/2 from both sides
[tex]-2-\frac{1}{2}=\frac{1}{2}+b-\frac{1}{2}\\-\frac{5}{2} = b[/tex]
Therefore, the y-intercept of the line is [tex]-\frac{5}{2}[/tex]. Plug this back into [tex]y=\frac{1}{2} x+b[/tex]
[tex]y=\frac{1}{2} x-\frac{5}{2}[/tex]

A zip line starts on a platform that is 40 meters above the ground. The anchor for the zip line is 198 horizontal meters from the base of the platform. How long is the zip line? *
Answer:
Solution given:
perpendicular distance =height [p]=40m
base or horizontal distance [b]=198m
Hypotenuse or zip line [h]=?
Now
By using Pythagoras law
h²=p²+b²
h²=40²+198²
h=√40804
h=202m
So the Zip line is 202m long.

The probability as a fraction is 5/11
============================================================
Explanation:
There are 250 red and 300 blue. This gives 250+300 = 550 total marbles.
Divide the number of red (250) over the number total (550) to get the fraction 250/550. Reduce this fraction by dividing both parts by 50. Note how 50 is the GCF of 250 and 550.
Let A = 250 and B = 550.
A/GCF = 250/GCF = 250/50 = 5 which is the numerator already written for usB/GCF = 550/50 = 11 will go in the blank in the denominatorThe fraction A/B = 250/550 fully reduces to 5/11.
We can think of it like saying "There are 5 red marbles out of 11 total".
5/11 = 0.4545 = 45.45% approximately

function h describes the height of a ball, in inches, after n bounces and is defined by the equation h(n)=120 x (4/5)^n.
What is h(3) ?
What does h(3) represent in this situation?
Answer:
Step-by-step explanation:
h(3) = 120*(4/5)^3, which evaluates to 120(64/125), or 61.64.
What does this mean: After 3 bounces the height of the ball is 61.64 ft.
