The following
statements are true by definition:
The side
opposite ∠L is NM.
The side
opposite ∠N is ML.
The side
opposite to the angle should not contain any letter of that side.
<span>The following
statements are not essentially true because we have no idea if triangle LNM
is a right triangle (if it is, then we do not know what the hypotenuse is):</span>
The
hypotenuse is NM.
The
hypotenuse is LN.
<span>The following
statements are not true:</span>
The side
adjacent ∠L is NM.
The side
adjacent ∠N is ML.
They are not
true because the side adjacent to an angle should have its letter on the side.
For example, the side adjacent to ∠L should be LN or LM and
for ∠N it should be NM or NL.

Understanding the Question
This may not be the actual way that the US government prepares the CPI, but it will provide a comparison.
You can set up a proportion. The base number for the CPI is 38.8 in 1970. That number (38.8) has more than doubled to get to 82.4, which also tells us that there was inflation. What your parents and grandparents bought in 1970 went to double the amount in 1980. Gasoline certainly did that.
Givens
CPI in 1970 = 38.8
CPI in 1980 = 82.4
Eggs 1970 = 0.25
Edgs 1980 = X
Formula substitution and solution
CPI 1970 / CPI 1980 = cost of eggs 1970 / cost of eggs 1980
38.8/82.4 = 0.25 / x Cross multiply
38.8 * x = 0.25 * 82.4
38.8 * x = 20.625
x = 20.628 /38.8
x = 0.53 dollars of 53 cents.
53 cents in 1980 which is slightly double as predicted.
Footnote
As a matter of interest, my wife tells me that eggs now cost about 3.58 where we live. That's almost 7 times as expensive as they were in 1980. Something to think about. By the way, the price quoted is in Canada.
Answer:
2 1/16, 10 11/16, 3 15/16
Step-by-step explanation:
3. 1 3/8 times 1 1/2= 2 1/16
4. 4 1/2 times 2 3/8= 10 11/16
5. 1 1/8 times 3 1/2= 3 15/16
Answer:
The length of this rectangle is 6 units.
Step-by-step explanation:
Let the width of the rectangle be x.
x • (x+2) = 48
x^2+2x=48
x^2+2x-48=0
x^2 - 6x + 8x - 48
x(x-6) 8(x-6)
(x+8)(x-6)
x=-8,6
Answer:
Rational
Step-by-step explanation:
An irrational number is a number with forever continuing decimals. Plug it into the calc and you can see if there is a long decimal line that ends. You should get 1.4 in the calc, and since it does end, it is a rational number.
