Answer:
60
Step-by-step explanation:
3×20 is 60, and it works with 5, and it is the smallest possible Multiple
Answer:
60
Step-by-step explanation:
Find the prime factorization of each number:
3 = 3
5 = 5
20 = 2^2 * 5
LCM = product of common factors with greatest exponent and non-common factors.
LCM = 3 * 5 * 2^2 = 15 * 4 = 60
which is greater 3/10 or 3%

How do I do this? And what’s the answer??
Answer:
its asking you what the slope of the line is (rise/run) and for the point at which the line crosses the y axis (verticle line)
Step-by-step explanation:
When finding the slope you count the number of units up and the number of units across. This would be -1/1 or -1 because the graph shows a scale of 100, and the slope is going down 100, and across 100. this makes the slope negative since it's going downwards. so the slope would be -100/100 which would simplify to -1.
the y-intercept is where the line crosses the y axis. if this point is below the x-axis, then the y-intercept would be negative. in this problem however, the line crosses the y-axis at the origin (0,0)
so your equation would be y=1x+0, but simplified it would be y=x (the one isnt used because there is a single x value and the +0 is gone because it holds no value)

f.
Answer:
a) 36
b) 8.5
c) 5/2
d) 6
e) 9
f) 8
Step-by-step explanation:
a) [tex]x \div 3 =12[/tex]
Multiply both sides by 3
[tex]x \div 3 =12\\3*(x \div 3) = 12*3\\x=36[/tex]
b) [tex]2x+3=20[/tex]
Subtracting 3 from both sides
[tex]2x+3-3=20-3\\2x=20-3\\2x=17\\x=\frac{17}{2}\\x=8.5[/tex]
c) [tex]\frac{4}{3}x=\frac{10}{3}[/tex]
Multiply both sides by 3/4
[tex]\frac{4}{3}x*\frac{3}{4} =\frac{10}{3} *\frac{3}{4}\\x=\frac{5}{2}[/tex]
d) [tex]-4x=-24[/tex]
Divide both sides by -4
[tex]-4x=-24\\\frac{-4x}{-4}=\frac{-24}{-4}\\x=6[/tex]
e) [tex]2(x-4)=10[/tex]
Divide both sides by 2
[tex]2(x-4)=10\\\frac{2(x-4)}{2}=\frac{10}{2}\\x-4=5\\Adding \ 4 \ on \ both \ sides\\x-4+4=5+4\\x=9[/tex]
f) [tex]-0.5x+1.1=-2.9[/tex]
Subtracting 1.1 on both sides
[tex]-0.5x+1.1-1.1=-2.9-1.1\\-0.5x=-4\\Divide \ both \ sides \ by \ -0.5\\\frac{-0.5x}{-0.5}=\frac{-4}{-0.5}\\x=8[/tex]
Calculate the variance of the following set of data.

Variance is the measurement of the spread between numbers in a given set of data.
The variance for the set is 12083.929
What is a variance?It is the measurement of the spread between numbers in a given set of data.
We have,
3, 33, 303, 233, 3, 73, 83, 63
The formula to find variance:
Find the means of the set of data.
Find the deviation of the set of data from the mean.
Find the sum of the squares of the mean deviations.
Divide the sum of the squares of the mean deviations by (n-1)
where n is the number of data in the set.
The mean:
= (3 + 33 + 303 + 233 + 3 + 73 + 83 + 63) / 8
= 794/8
= 99.25
Deviation from the mean:
3 - 99.25 = -96.25
33 - 99.25 = -66.25
303 - 99.25 = 203.75
3 - 99.24 = -96.25
73 - 99.25 = -26.25
83 - 99.25 = -16.25
63 - 99.25 = -36.25
The sum of the squares of Mean deviation:
= 9264 + 4389 + 41514 + 9264 + 689 + 264 + 1314
= 84587.5
The variance:
= 84587.5 ÷ (8 - 1)
= 84587.5 / 7
= 12083.929
Thus,
The variance for the set is 12083.929

Answer:
The price that Camilla paid for the book was $9.
Step-by-step explanation:
To be able to find the pice that Camilla paid for the book, first, you have to calculate the 25% of the price of the book:
$12*25%=$3
Now, you have to subtract that amount from the price of the book:
$12-$3=$9
According to this, the answer is that the price that Camilla paid for the book was $9.

The ratios 250 miles in 4 hours and 500 miles in 8 hours are equivalent.
Answer:
Yes, they are equivalent
Step-by-step explanation:
Case 1,
Distance = 250 miles
Time = 4 hours
Ratio = speed = distance/time
= 250 miles/4 hour
= 62.5 mph
Case 2,
Distance = 500 miles
Time = 8 hours
Ratio = speed = distance/time
= 500 miles/8 hour
= 62.5 mph
In both cases, the ratios 250 miles in 4 hours and 500 miles in 8 hours are equivalent.
