If three circular metal discs of equal thickness whose radii are 5cm, 20cm and 40cm are melted down to form one circular disc of the same thickness, find its radius.
Answer: 45 (cm)
Step-by-step explanation:
Since the discs have the same thickness, we will think about the areas.
Let say x the new radius:
[tex]\pi*5^2+\pi*20^2+\pi*40^2=\pi*x^2\\\Longrightarrow\ 5^2+20^2+40^2=x^2\\\\\Longrightarrow\ 2025=x^2\\\\\Longrightarrow\ x=\sqrt{2025} =45[/tex]
Help meeeeeee on this math hw
Answer:
Step-by-step explanation:
What do you know about y?
Nothing. It could be odd or even. You can't take the chance. So you need to start your list with 2y
That means that 2y + 2 is the second member in your list
2y + 4
2y + 6
2y + 8
2y + 10
But notice you only have 5 numbers. 2y + 10 cannot be the answer.
The answer must be 2y + 20

Answer:
Page 3 - the y-intercept would remain at 5 and the slope would be 3 times the upward slope.
Page 5 - the y-intercept would remain at -2 and the slope would be 1/4 instead of 5
Step-by-step explanation:
In point slope form the slope and y-intercept can be read directly from the equation.
y = mx + b where m is the slope and b is the y-intercept.
On the first day of class, Willem’s Algebra I teacher agreed to assign no homework for a week to the first student to answer this question: There is a positive two-digit integer that is divisible by the sum of its digits and has exactly five factors. What is the sum of its factors? (This is for my little sister in middle school)
Answer:
81
Step-by-step explanation:
There are only two numbers with 5 factors that are only two digits. 16 and 81 are the only options and when you add 8+1=9 and 81 is divisible by 9.

Find the measure of the missing angle of each
Answer:
? = 120, ? = 145, respectively
Step-by-step explanation:
? + 60 = 180
? (+ 60 - 60) = 180 - 60
? = 120
35 + ? = 180
(35 - 35) + ? = 180 - 35
? = 145
Which decimal is equivalent to 8/11 ?

Locker combinations consist of numbers 1-30 on the dial. Every locker combo is 3
numbers. How many different locker combinations are there? (Enter the number only -
no labels)
This is the number 27 thousand
==============================================
Explanation:
There are three slots and 30 choices per slot. Repeats are allowed.
So there are 30*30*30 = 27,000 different locker combos.
30. -3a^2= -3-6^2 is this correct? And I have to evaluate o I am not good at that so if u can help THANK YOU so much!

Answer:
X (2, 1)
Y (2, 3)
W (5, 5)
Step-by-step explanation:
The current points are:
X (-2, -1)
Y (-2, -3)
W (-5, -5)
Now, after rotating 180 degrees around the origin, here is what points Y, Y, and W would look like:
X (2, 1)
Y (2, 3)
W (5, 5)
Plot these new points on the graph, and you'll have a new figure which will be rotated to 180 degrees.
I have also provided you with a graph, showing both, the original and the rotated version, below.

(cough cough) free, ,points
Here is a room with two lasers. Your goal is to get to the opposite side of the room. However there is a catch; if you do not stay equidistant from each laser, you will be blasted. Describe in a Word document how you would find the straight-line path across the room. Be sure to use correct geometric terminology from what you have learned so far.
Step-by-step explanation:
we would calculate the line of sight between the 2 lasers.
then we would create a line that goes through the middle point between the 2 lasers and is perpendicular to the line between the lasers. if we are lucky, then "You" is on the same perpendicular line. if not, we need to shift our starting point to a point where the perpendicular line hits the wall of the room.
by following that perpendicular line precisely, we we always have the same distance from both lasers.
can somebody help me with this? thanks and brainliest giving!

Answer:
r =√[3V/(π h)]
Step-by-step explanation:
V = ⅓ × π r²h
=> multiplied by 3
3V = π r² h
=> find r²
r² = 3V/(π h)
=> find r
r =√[3V/(π h)]
Answer:
[tex]r=\sqrt{\dfrac{3V}{\pi h}}[/tex]
Step-by-step explanation:
Given equation:
[tex]V=\dfrac{1}{3} \times \pi r^2 h[/tex]
To isolate [tex]r[/tex], multiply both sides by 3:
[tex]\implies V \times 3=\dfrac{1}{3} \times \pi r^2 h \times 3[/tex]
[tex]\implies 3V= \pi r^2 h[/tex]
Divide both sides by [tex]\pi h[/tex]:
[tex]\implies \dfrac{3V}{\pi h}= \dfrac{\pi r^2 h}{\pi h}[/tex]
[tex]\implies \dfrac{3V}{\pi h}=r^2[/tex]
Square root both sides:
[tex]\implies \sqrt{r^2}=\sqrt{\dfrac{3V}{\pi h}}[/tex]
As the radius is positive only:
[tex]\textsf{Apply radical rule} \quad \sqrt{a^2}=a, \quad a \geq 0[/tex]
[tex]\implies r=\sqrt{\dfrac{3V}{\pi h}}[/tex]

91.) A car is traveling at 5 m/s. How far has it gone in 12 seconds?
5 m/s · 12 s = 5 m · 12 = 60 m
Answer: in 12 seconds that car has gone 60 metres.
Answer:
A car travels at a constant rate of 5 metres per second.
That means that for every second,the car travels 5m/s.
The question is asking you for how far the car travelled after 12 seconds.Muntiply 12 to bottom and top.
5m/1s*12/12=60/12
The car travels 60 metre in 12 seconds
