Answer:
Sometimes, it is true
Step-by-step explanation:
The L. C. M of two numbers could be the product of the two Given numbers. This happens sometimes but not always. For instance, the Lowest Common. Multiple of 4 and 5 is 20
4 : 4, 8, 12, 16, 20, 24, 28, 32
5 : 5, 10, 15, 20, 25,...
L. C. M = 20 ; 4 * 5 = 20
However, L. C. M of 4 and 8
4 : 4, 8, 12, 16, 20, 24, 28, 32
8 : 8, 16, 24, 32, 40
L.C.M = 8 ; 4 * 8 = 32
HENCE, L. C. M could be the product of the 2 numbers sometimes and it may not in other scenarios.

What is the slope of the line shown below?
Answer: -4
Step-by-step explanation:
If you are given a problem like this with two points, the easiest way to find the slope is using the equation [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex] with points [tex](x_{1}, y_{1})[/tex] and [tex](x_{2}, y_{2})[/tex].
In this problem, by looking at the graph, you can identify the points (0, 10) and (5, -10)
Let's label these numbers:
x1 = 0x2 = 5y1 = 10y2 = -10Now, plug these numbers into the formula above. That gives you [tex]\frac{-10-10}{5-0}[/tex].
-10 - 10 = -20 and 5 - 0 = 5, which gives you a fraction of [tex]\frac{-20}{5}[/tex], which can be simplified down to -4.

Zeke is racing his little brother Niko. They are running a total of 30 yards and Zeke gives Niko a 12 yard head start. Zeke runs 2 yards every second but Niko only runs 1 yard every 2 seconds. If x represents the number of seconds they have been racing and y represents the distance from the start line then:
Fill out the table below for various distances that Zeke and Niko are from the start line at the given times
X (sec) Zeke Distance (yd) Niko Distance (yd)
0 0 12
2
6
Answer: Zeke will catch up with Niko at 16 yards from the start line, y = 16 yards.
Zeke will catch up Niko after 8 seconds, x = 8 seconds.
Step-by-step explanation: i) distance to be run = 30 yards
ii) Niko has a head start of 12 yards.
iii) speed of Zeke = 2 yards / second
iv) speed of Niko = 1 yard every 2 seconds = 0.5 yard / second
v) x represents the number of seconds they have been racing.
vi) y represents the distance from the start line.
vii) the time at which Zeke catches up with Niko will be given by
Therefore 2y - 24 = 0.5y 1.5 y = 24 y = 24 / 1.5 = 16 yards
Therefore x = 16 /2 = 8 seconds

I have to repost this because I was giving wrong answers. The instructions are to complete each proof using the properties of equality
Answer and Step-by-step explanation:
We are given:
[tex]\frac{2y-1}{-3} = 5[/tex]
First, we multiply both sides by -3.
2y - 1 = 15
Now we add 1 to both sides.
2y = 16
Finally, we divide by 2 to each side.
y = 8
We are given:
2x + 30 = -4(5x -2)
First we distribute the -4 to 5x and -2.
2x + 30 = -20x + 8
Now we subtract 8 from both sides.
2x + 22 = -20x
Now we subtract 2x from both sides.
22 = -22x
Finally, we divide by -22 to both sides.
-1 = x

and 10 stickers, and wants each party bag to include the same combination
of pencils and stickers, with none left over. What is the greatest number of
party bags she can make?
Answer:
5
Step-by-step explanation:
It's pretty simple you just need to factor each number and find the number that they have in common.
find the factors of 15. factors are the terms (numbers) you need to multiply to get your product (answer to a multiplication problem. the factors of 15 are: 1,3,5,15find the factors of 10. the factors of 10 are: 1,2,5,10If you take a look, the only number (and the smallest number) that these 15 and 10 have in common is 5 and that is your answerWhich of the following is a radical equation?
A. x StartRoot 3 EndRoot = 13
B. x + StartRoot 3 EndRoot = 13
C. StartRoot x EndRoot + 3 = 13
D. x + 3 = StartRoot 13 EndRoot
Answer:
C. StartRoot x Endroot + 3 = 13
Step-by-step explanation:
the x variable under the root is what makes it a radical. all of the others dont have an x variable under the root. hope this helps !
What is 1/4 exponent 3 equal to in fraction form. Help as soon as possible plz
Answer:
Step-by-step explanation:
(1/4)^3=1^3/4^3=1/64
Here we need to use the exponent property:
[tex](\frac{a}{b} )^n = \frac{a^n}{b^n}[/tex]
Using this, we will see that the given expression is equal to:
[tex]\frac{1}{64}[/tex]
We start with:
[tex](\frac{1}{4} )^3[/tex]
Now we can use the above property to rewrite this as:
[tex](\frac{1}{4} )^3 = \frac{1^3}{4^3}[/tex]
Now we know that:
1^3 = 1
4^3 = 4×4×4 = 16×4 = 64
Now we can replace these in the above expression to get:
[tex](\frac{1}{4} )^3 = \frac{1}{64}[/tex]

While measuring a wire a 5cm wire, a construction worker measured it 5.2 cm by mistake. What is the percent error?
Answer:
4%
Step-by-step explanation:
Actual length of wire = 5 cm
The measured length of wire = 5.2 cm
We need to find the percent error in the measurement of the length of wire. It can be calculated as follows :
[tex]\%=\dfrac{\text{measured length-actiual length}}{\text{actual length}}\times 100\\\\=\dfrac{5.2-5}{5}\times 100\\\\=4\%[/tex]
So, the required percent error is 4%.
