Sort the numbers from LEAST TO GREATEST . > 6.82 , 6.803 , 6.650 , 6.68
Answer:
6.650, 6.68, 6.803, 6.82
Step-by-step explanation:
You just treat the decimals as you would whole numbers. Try imagineing them as whole numbers and its a lot easier like this. 6.82 and 6.68 as 682 and 668, you can clearly see 668 is lower than 682 so it comes first. Therefore, 6.68 is lower than 6.82 and comes first.

A cylinder has a diameter of 18cm and a height of 4cm.
The radius is 12cm
The volume of the cylinder is324 п cm
The volume of the cylinder is1296 п cm
The area of the base of the cylinder is 81 п cm?
Answer:
The volume of the cylinder is324 п cm
The area of the base of the cylinder is 81 п cm
Step-by-step explanation:
volume of a cylinder = nr^2h
n = 22/7
r = radius = 18/2 = 9
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
n x (9^2) x 4 = 324n
Area of the base of the cylinder : Area of a circle = πr² = π x 9^2 = 81 π

Increase 18 by a half
Answer:
36
Step-by-step explanation:
if we were decreasing it would be 9 but if we are increasing it, it would be 36
just multiply by 2 or divide by 2
Answer:
27
Step-by-step explanation:
increasing by 1 half is like dividing. 4 increased by one half would be 6, because half of four is 2, and you add that on to four. increasing 18 by half, divide 18 by 2, that = 9 then add 9 onto 18. the answer is 27
What is true about the figure?
In the figure, angles C and D are a
Therefore, angle C must measure
B = ?
C = ?
A = ?
D = 124°
Answer:
<A = 56degrees
<B = 34degrees
<C = 56degrees
Step-by-step explanation:
From tyhe diagram, the sum of m<C and m<D is 180degrees. Hence;
<C + <D = 180
<C + 124 = 180
<C = 180 - 124
<C = 56degrees
Also;
<B + 90 + <C = 180
<B + 90 + 56 = 180
<B + 146 = 180
<B = 180 - 146
<B = 34degrees
Similarly;
<A + <B = 90
<A + 34 = 90
<A = 90 - 34
<A = 56degrees
During a storm one and five hundredths inches of rain fell near Marie's house which shows the amount of rain in standard form?
Answer:
1.05 * 10⁰
Step-by-step explanation:
Standard form is a way of representing either very large or very small numbers easily.
If a number is to be written in standard form, you have to first write down the number between 1 and 10, then you write × 10(to the power of a number).
Given that the amount of rain that fell near Marie's house is one and five hundredths inches of rain.
Amount of rain = one and five hundredths inches of rain = 1 + 5/100 = 1 + 0.05 = 1.05
Amount of rain in standard form = 1.05 * 10⁰
Find the slope of the line through the given points.
(-1,1) and (3, -7)
Answer:
Slop of the line M = -2
Step-by-step explanation:
Given coordinates;
(-1 , 1) , (3 , -7)
Find:
Slop of the line
Computation:
We know that;
x1 = -1
x2 = 3
y1 = 1
y2 = -7
Slop of the line M = Δy / Δx
Slop of the line M = (y2 - y1) / (x2 - x1)
Slop of the line M = (-7 - 1) / [3 - (-1)]
Slop of the line M = (-8) / [3 + 1]
Slop of the line M = (-8) / (4)
Slop of the line M = -2

Joe said that if you roll a number cube 6 times, one of those rolls will be a 1. Was Joe correct? Why or why not.
Answer:
He was incorrect because...
Step-by-step explanation:
Although there is a CHANCE that a 1 will be rolled. There is also a chance to rolls all 6's, or all 5's for example. The chance that a 1 will be rolled is 1/6, or ~16.67%.
Joe is not correct.
We have a statement said by joe - if you roll a number cube 6 times, one of those rolls will be a 1.
We have to investigate whether joe is right or not?
What are all possible outcomes if you roll a number cube?When you roll a number cube the possible outcomes are - 1, 2, 3, 4, 5, 6.
If we consider statement said by joe - he expressed the certainty of the occurrence of 1. According to him, if you roll a number cube 6 times, then the probability of the Event (say A) - one of those rolls will be 1 is :
P(A) = 1 (the event will 100% occur)
However, when a number cube is rolled 6 times, the total number of possible outcomes = 6 x 6 = 36. The total number of favorable outcomes are = 6.
Therefore, the probability that the event - one of the rolls will be 1 is
[tex]P(A) =\frac{6}{36}= 0.16[/tex]
This means that the probability of occurrence of event is 16%.
Hence, Joe is not correct.

If 2/3 is multiplied by a fraction greater than 1, which of these could be the product?
Answer:
Any number bigger than 2/3
Step-by-step explanation:
btw, I didn't see the options but here's the explanation
When you multiply by a part of a whole, a fraction, you are getting smaller. When you multiply by a number bigger than one, your product gets bigger. So, any number bigger than 2/3 works just fine

10-36. Talayna has some money that she wants to put into a savings account and she has two
options. One option pays 2% interest compounded quarterly. Another option pays only 1.5%,
but is compounded monthly. If she wants to deposit the money for 5 years, which account is
better? If she wants to deposit for 25 years, which account is better? Homework Help
Plzzz
Answer:
Option 1
Step-by-step explanation:
Effective Interest Rate = [ 1 + ( r / m) ]^ mt - { 1 }
where i = nominal interest rate , n = number of compounding per time period, t = number of time periods
Option 1 : Interest rate 'i' = 2% , Quarterly compounding 'n' = 4 , t = 25 years
EAR = [ 1 + 2% / 4 ]^ (4 x 25) - [ 1 ] = 0.6466 , ie 64.66%
Option 2 : Interest rate 'i' = 2% , Monthly compounding 'n' = 12 , t = 25 years
EAR = [ 1 + 1.5% / 12 ] ^ (12 x 25) - [ 1 ] = 0.4546 , ie 45.46%
As option 1 has higher EAR than option 2, former is better than latter

Which is the best description for the lines m and k?
A)
parallel
B)
perpendicular
intersecting and parallel
D
intersecting but not perpendicular
===================================================
Explanation:
I've highlighted lines m and k in red (see diagram below). We'll ignore the other lines. On those red lines, I've added blue points with their coordinate locations.
Line m has point A = (-3, 5) and B = (-1, -3). Let's use the slope formula to find the slope through these points
m = (y2-y1)/(x2-x1)
m = (-3-5)/(-1-(-3))
m = (-3-5)/(-1+3)
m = -8/2
m = -4
The slope of line AB, aka line m, is -4.
-------------
Line k has points C = (1, 5) and D = (3, -3) on it. We'll use the slope formula to get...
m = (y2-y1)/(x2-x1)
m = (-3-5)/(3-1)
m = -8/2
m = -4
The slope of line CD, aka line k, is -4
---------------
Both lines m and k have the same slope of -4. Therefore, the two lines are parallel. Parallel lines always have the same slope, but different y intercepts. So these lines will never intersect one another.
