Mr. Brackett works in factory with his two sons. He is really happy with his job because he gets to spend some time with his beloved sons not only at home but also at work! He is allowed to take a break every 140 minutes while his two sons are allowed to take breaks in 210 minutes and 280 minutes. How many minutes will they have to wait after their first break together to get together again?
Answers
Answer:
840 minutes
Step-by-step explanation:
We solve this question using the LCM Method
Find and list multiples of each number of minutes which is given in the quest as 140, 210 and 280 minutes until the first common multiple is found. This is the lowest common multiple.
Multiples of 140:
140, 280, 420, 560, 700, 840, 980, 1120
Multiples of 210:
210, 420, 630, 840, 1050, 1260
Multiples of 280:
280, 560, 840, 1120, 1400
Therefore,
LCM(140, 210, 280) = 840
Therefore, they would have to wait after their first break together to get together again after 840 minutes

Container A is cylinder with a radius of 10 units and a height of 10 units. A right cone has been carved from its base and has a height of 10 units. Container B has the same radius as container A. Which statement derives the formula to find the volume of container A?
container A is a right cylinder that has had a right cone subtracted from its base, container B is half of a sphere
1 over 3π(102)(10) − π (102)(10)
2[1 over 3π(102)(10) − π(102)(10)]
π(102)(10) − 1 over 3π(102)(10)
2[π(102)(10) − 1 over 3π(102)(10)]
Answers
Answer: π(10^2)(10) − 1/3π(10^2)(10)
Step-by-step explanation:
Container A is a cylinder so the equation is π(r^2)(h)
Container B is a right cone so that equation is 1/3π(r^2)(h)
You would plug in the numbers and then subtract A from B
The formula to find volume of cylinder of container A is πr²h - 1/3π²h.
Thus Option (c) is correct
What is volume cylinder?The volume of cylinder is "the density of the cylinder which signifies the amount of material the cylinder can carry".
According to the question,
Container A is "cylinder with a cylinder of radius of 10 units and has height is 10 units. Container B is cylinder with a cylinder of radius of 10 units and has height is 10 units. A right cone has base and has a height 10 units.
In order to find volume of container A only if subtract volume of cone from volume of cylinder
Formula for volume of cylinder = πr²h
Formula for volume of cone = 1/3π²h
Formula for volume of container A = πr²h - 1/3π²h
Hence, the formula to find volume of cylinder of container A is πr²h - 1/3π²h. Thus, Option (c) is correct

So first, the ratio we know is 5:4 which in other words is 5x:4x. We also know that there are 60 clownfish. So that means 5x = 60 --> x = 12. So then 4x has to equals 12 x 4 which is 48.
b. 36
So first, the ratio we know is 4:3 which in other words is 4x:3x. We also know that there are 48 angelfish. So that means 4x = 48 --> x = 12. So then 3x has to equals 12 x 3 which is 36.

The height of the tree is 4.12 m.
Given,
I put a ladder 1.5m away from a tree.
The ladder is inclined at 70 degrees about the horizontal.
We need to find out what is the height of the tree.
What is the formula for tangent in trigonometry?
It is given by:

C /_70°_______ | B
<--------1.5m-------->
Find the AB.
AB = height of the tree.
TanФ = AB / CB
Tan 70° = AB / 1.5m
2.7474 = AB / 1.5m
AB = 2.7474 x 1.5m
AB = 4.12 m

Write a quadratic equation given the roots -1/3 and 5, show your work
Answers
[tex] \boxed{(x - a)(x - b) = 0}[/tex]
The equation above is the intercept form. Both a-term and b-term are the roots of equation.
[tex]x = - \frac{1}{3} \\ x = 5[/tex]
These are the roots of equation. Therefore we substitute a = - 1/3 and b = 5 in the equation.
[tex](x + \frac{1}{3} )(x - 5) = 0[/tex]
Here we can convert the expression x+1/3 to this.
[tex]x + \frac{1}{3} = 0 \\ 3x + 1 = 0[/tex]
Rewrite the equation.
