Answer:
The answer is 33 bouncy balls in each machine
Step-by-step explanation:
In order to determine the answer, we need to divide every bouncy ball bags by two. The information about the amount of balls in every bag is:
bag 27 mm= 180 balls
bag 40 mm= 80 balls
The bag of 27 mm has an even amount of balls, so if we divide it by two, there will be 90 balls in each machine.
The bag of 40 mm has an even amount of balls, so if we divide it by two, there will be 40 balls in each machine.
Finally, considering the division in every bag, each machine has 130 balls.
A weightlifter holds a 1,700 N barbell 1 meter above the ground. One end of a 2-meter-long chain hangs from the center of the barbell. The chain has a total weight of 500 N. How much work (in J) is required to lift the barbell to a height of 2 m
The work required to lift the barbell to a height of 2 m is 1,700 J.
Explanation:To calculate the work required to lift the barbell to a height of 2 m, we need to consider the gravitational potential energy. The work done is equal to the change in potential energy.
The initial potential energy of the barbell is equal to its weight multiplied by the initial height, which is 1,700 N * 1 m = 1,700 J.
The final potential energy of the barbell is equal to its weight multiplied by the final height, which is 1,700 N * 2 m = 3,400 J.
Therefore, the work required to lift the barbell to a height of 2 m is 3,400 J - 1,700 J = 1,700 J.

A triangle has one angle measuring 3X degrees the second angle measures 2X +20° and the third angle measures 4X -20° what is the value of X
Answer:
[tex]x=20[/tex]
Step-by-step explanation:
We have been a triangle has one angle measuring [tex]3x[/tex] degrees the second angle measures [tex]2x+20[/tex] degrees and the third angle measures [tex]4x-20[/tex] degrees. We are asked to find the value of x.
We know that all interior angles of a triangle add up-to 180 degrees.
[tex]3x+2x+20+4x-20=180[/tex]
Combine like terms:
[tex]3x+2x+4x-20+20=180[/tex]
[tex]9x=180[/tex]
Divide both sides by 9:
[tex]\frac{9x}{9}=\frac{180}{9}[/tex]
[tex]x=20[/tex]
Therefore, the value of x is 20 for our given triangle.

please help me solve this maths problem ☺
Answer:
lets
h =# of hens in the filed and c = # of cows in
the field
hens and cows have 50 heads
h + c = 50 (1)
hens and cows have 180 legs (hen has 2
legs and cow has 4 legs)
2h+4c180 (2)
From equation (1) h + c = 50 ----> h = 50 - c
substitute h = 50 c into 2h + 4c = 180 (
-
2h+4c 180
2(50-c) + 4c = 180
1002c+ 4c = 180
2c 180-100
2c=80
C = 40
2h + 4(40) = 180
2h+160 180
2h = 20
h = 10
answer
hens = 10 and cows = 40
double check:
heads: 10 hens + 40 cows = 50 total legs:10(2) + 40(4) = 20 + 160 = 180

The main cable of a suspension bridge forms a parabola, described by the equation y = a(x - h)2 + k, where y is the height in feet of the cable above the roadway, x is the horizontal distance in feet from the left bridge support, a is a constant, and (h, k) is the vertex of the parabola. At a horizontal distance of 30 ft, the cable is 15 ft above the roadway. The lowest point of the cable is 6ft above the roadway and is a horizontal distance of 90 ft from the left bridge support.Which quadratic equation models the situation correctly?
The main cable attaches to the left bridge support at a height of ft.
The main cable attaches to the right bridge support at the same height as it attaches to the left bridge support. What is the distance between the supports?
Answer:
26.25 ft.
Step-by-step explanation:
The general form of a parabola is [tex]y = a(x - h)^2 + k[/tex], where the vertex of the parabola is (h,k).
The equation of the parabola is [tex]y = 0.0025(x - 90)^2 + 6[/tex].The distance between the supports at a vertical height of 26.25 is 180ftGiven that
[tex]y = a(x - h)^2 + k[/tex]
A. The quadratic equation
The lowest point (which stands for the vertex) is given as:
[tex](h,k) = (90,6)[/tex]
So, we have:
[tex]y = a(x - 90)^2 + 6[/tex]
From the question, we understand that:
At a horizontal distance of 30ft, the cable is at 15ft. This means:
[tex](x,y) = (30,15)[/tex]
Substitute these values in: [tex]y = a(x - 90)^2 + 6[/tex]
So, we have:
[tex]15 = a(30 - 90)^2 + 6[/tex]
[tex]15 = a(- 60)^2 + 6[/tex]
[tex]15 = a \times 3600 + 6[/tex]
Collect like terms
[tex]3600a = 15 - 6[/tex]
[tex]3600a = 9[/tex]
Make a, the subject
[tex]a = \frac{9}{3600}[/tex]
[tex]a = 0.0025[/tex]
Substitute [tex]a = 0.0025[/tex] in [tex]y = a(x - 90)^2 + 6[/tex].
[tex]y = 0.0025(x - 90)^2 + 6[/tex]
B. The horizontal distance at a height of 26.25ft.
This means that, y = 26.25
So, we have:
[tex]26.25 = 0.0025(x - 90)^2 + 6[/tex]
Collect like terms
[tex]-6 + 26.25 = 0.0025(x - 90)^2[/tex]
[tex]20.25= 0.0025(x - 90)^2[/tex]
Divide both sides by 0.0025
[tex]8100 = (x - 90)^2[/tex]
Take square roots of both sides
[tex]\±90 = x - 90[/tex]
Solve for x
[tex]x = 90 \± 90[/tex]
To the left of the cable, the horizontal distance is:
[tex]x_1 = 90 - 90[/tex]
[tex]x_1 = 0[/tex]
To the right of the cable, the vertical distance is:
[tex]x_2 = 90 + 90[/tex]
[tex]x_2 = 180[/tex]
So, the coordinates of the left and right support at a height of 26.25 is:
(0,26.25) and (180, 26.25)
The distance (d) between them is calculated using:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 -y_1)^2}[/tex]
[tex]d = \sqrt{(180- 0)^2 + (26.25-26.25)^2}[/tex]
[tex]d = \sqrt{180^2 + 0^2}[/tex]
[tex]d = \sqrt{180^2}[/tex]
[tex]d = 180[/tex]
The distance between them is 180ft

Answer:
243 ft2
Step-by-step explanation:
9*3= 27
