A cell phone beeps every 4 minutes. Another cell phone beeps every 5 minutes. What are the first three times that the cell phones beep at the same time?
Answer:
20, 40, 60
Step-by-step explanation:
We can find the LCM by making a list which is my favorite way.
Cell phone number 1: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60
Cell phone number 2: 5, 10, 15, 20, 25, 30, 35 40, 45, 50, 55, 60
Answer:
The first three times that the cell phones beep at the same time are the 20th, 40th and 60th minutes.
Step-by-step explanation:
Let the first cell phone be A, that is, A beeps every 4 minutes
and let the other cell phone be B, that is, B beeps every 5 minutes.
Cell phone A will be at the 4th, 8th, 12th, 16th and 20th minutes while cell phone B will beep at the 5th, 10th, 15th and 20th minutes. Hence, the first time the cell phones will beep together is the 20th minute.
Cell phone A will then beep at the 24th, 28th, 32nd, 36th and 40th minutes while cell phone B will beep at the 25th, 30th, 35th and 40th minutes. The second time the cell phones will beep together is the 40th minute.
Cell phone A will beep at the 44th, 48th, 52nd, 56th and 60th minutes while cell phone B will beep at the 45th, 50th, 55th and 60th minutes. The third time the cell phones will beep together is the 60th minute.
Hence, the first three times that the cell phones beep at the same time are the 20th, 40th and 60th minutes.
what is x to the power of two =36 over 121
Answer:
x = ± [tex]\frac{6}{11}[/tex]
Step-by-step explanation:
Given

if there is a strong correlation between two variables the correlation coefficient will be close to -1 or 1 true or false
=================================================
Explanation:
r = correlation coefficient
If r is close to -1, then the points are close to (or some fall on) the same straight line that has a negative slope. We consider this be a strong negative linear correlation.
If r is close to +1 or just 1, then the points are close to the same straight line that has a positive slope. These points would be considered to have strong positive linear correlation.
By "same straight line", I mean the regression line or line of best fit.

1/4 Divided By 9/10=
Answer:
[tex]\frac{5}{18}[/tex]
Step-by-step explanation:
When dividing fractions, the formula is simple: Keep Flip Change (KFC)
So keep [tex]\frac{1}{4}[/tex] change your division sign to a multiplication sign, and flip [tex]\frac{9}{10}[/tex] so it becomes [tex]\frac{10}{9}[/tex].
[tex]\frac{1}{4}[/tex]·[tex]\frac{10}{9}[/tex]=[tex]\frac{10}{36}[/tex]
Then you need to reduce your fraction to simplest form.
[tex]\frac{5}{18}[/tex]
What would be the answer for -2 -12n=-303
Answer:
25.08
Step-by-step explanation:
-12n - 2 = -303
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, n. Do the opposite of PEMDAS.
First, add 2 to both sides:
-12n - 2 (+2) = -303 (+2)
-12n = -303 + 2
-12n = -301
Next, divide -12 from both sides:
(-12n)/-12 = (-301)/-12
n = -301/-12 = 301/12
n = 25.08 (rounded).

A delivery person uses a service elevator to bring boxes of books up to an office. The delivery person weighs 160 lb and each box of books weighs 40 lb. The maximum capacity of the elevator is 670 lb. How many boxes of books can the delivery person bring up at one time?
Answer:
Step-by-step explanation:
So if the delivery person weights 160 lbs than we’re going to subtract 670-160=510 next we divide 40 into 510 which is 12.75. Which means that he can bring 12 boxes.
Answer:
12
Step-by-step explanation:
max cap 670lb- delivery person 160lb weight left 510lb
weight 510lb/each box 40lb number of boxes 12.75lb
each box 40lb times number of boxes 12lb 480lb+160lb 640lb
so your still have 30 lb before max weight of elevator
Write the equation of a line with a slope of 4 and a y-intercept of −3.
Answer: y=4x-2
Step-by-step explanation:
Slope-intercept form: y=ax+b, where a is the slope and b is the y-intercept.
Given: slope is 4, and y-intercept is -3
y=ax+b
y=4x+(-3)
y=4x-3

Line AB and line CD intersect at point E, with point E between A and B and between C and D. Which rays are opposite rays?
Answer:
EA, EB, EC and ED are opposites rays.
Step-by-step explanation:
Given that,
Line AB and line CD intersect at point E.
According to figure,
We need to find opposite rays
Using diagram
We draw a first line AB and second line CD which is intersect of AB at point E.
Now, EA and EB is called opposite ray of first line AB.
Similarly,
EC and ED is called opposite ray of first line CD.
Hence, EA, EB, EC and ED are opposites rays.
If k is a positive integer and n = k(k + 7), is n divisible by 6 ? (1) k is odd. (2) When k is divided by 3, the remainder is 2.
Answer:
1.) Yes
2.) Yes
Step-by-step explanation:
Given that
n = k(k + 7)
If k is a positive integer and n = k(k + 7), is n divisible by 6 ?
(1) k is odd. Yes.
Let assume that k = 3
Then, n = 3(3 + 7)
n = 3 × 10
n = 30.
30 is divisible by 6.
(2) When k is divided by 3, the remainder is 2. That is,
Let k = 5
Then,
5/3 = 1 remainder 2
Substitute k into the equation
n = k(k + 7)
n = 5(5 + 7)
n = 5 × 12
n = 60
And 60 is divisible by 6.
Therefore, the answer to both questions is Yes.

0.29 rounded? I need this for msth and quick!!
Answer:
0.29 rounded to the nearest ones is 0.
0.29 rounded to the nearest tenths is 0.3
0.29 rounded to the nearest hundredths is 0.29
Step-by-step explanation:
Note that when rounding, you always look at the place value directly next to the one you are rounding. Note that if the digit is 5 or greater, round up; If 4 or less, round down.
Round to the nearest ones:
Look at the place value directly next to the ones (tenths place value). It is a 2. Because 2 is less than 5, round down:
0.29 rounded to the nearest ones is 0.
Round to the nearest tenths:
Look at the place value directly next to the tenths (hundredth place value). It is a 9. Because 9 is greater than 5, round up:
0.29 rounded to the nearest tenths is 0.3
Round to the nearest hundredths:
Look at the place value directly next to the hundredths (thousandths place value). Because there is no number, it is typically signified by a 0 (place holder).
0.29 rounded to the nearest hundredths is 0.29

The traffic lights at three different road crossings change after every 48 seconds 72 seconds and 108 seconds respectivily.If they changed simultaneously at 7:00 am.,at what time will they change simultaneously again
Answer:
07:43: 12 AM
Step-by-step explanation:
Given that:
Traffic lights change after every 48, 72 and 108 seconds.
They changed simultaneously at 7:00 AM.
To find:
At what time, they will change simultaneously again ?
Solution:
For this, we need to find LCM(Least Common Multiple) of the three numbers and then add it to 7:00 AM to find the time they will change together again.
Because LCM of 3 numbers is the least number which is divisible by all 3 numbers.
Let us factorize the numbers and underline the common part:
[tex]48 = \underline{12}\times 4\\72 = \underline{12}\times 6\\108 = \underline{12}\times 9[/tex]
Common part is taken only once and the remaining part is multiplied to it to find the LCM.
So, LCM = [tex]12 \times 4\times 6 \times 9 = 2592[/tex]
In 2592 seconds, they will change together again.
Changing 2592 seconds in minutes:
Let us divide it by 60:
We get 43 minutes 12 seconds.
Let us add it to 7:00AM, we get the following:
So, the time at which they will change simultaneously = 07:43: 12 AM
