Which of the following of appropriate units of measure to use when finding the mass of a pencil?
a. kilograms
b. meters
c. Grams
d. centimeter
Answer:
Grams
Step-by-step explanation:
Mass is the amount of matter present inside a solid. Kilograms and grams are the units to measure mass of an object.
For pencil, the unit to measure its mass is grams. As its mass is less, we can use smaller unit.
Hence, the correct option is (c) "grams"

Answer:
SAS
Step-by-step explanation:
Count the number of sides marked congruent. One is marked with a single hash mark, and one is marked with a double hash mark, for a total of two.
That means the chosen congruence theorem will have S appear twice in its name, excluding AAS, ASA, and SSS.
We also note that the angles between the marked sides are vertical angles, hence congruent. The theorem that depends on two sides (SS) and the angle between them (_A_) is the SAS theorem.
It’s estimated that 800 people would attend the play, but 752 people actually attend.
What is the percent error, to the nearest percent, of the estimate? Enter the answer in the box.
*has blank box* percent error
Answer:
6
Step-by-step explanation:
752/800=0.94
0.94x100=94
100-94=6
The percent error, to the nearest percent, of the estimate is 6%
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
We need to Write the percent as a fraction in simplest form
16.24%
So, we can rewrite it as;
16.24 / 100
16 and 24/100 or 16 6/25
So the percent as a fraction is 16 6/25
Given:
Expected value = 800
Actual value = 752
Now, Percent error
Computation;
Percent error = [(Actual value - Expected value)/Expected value]100
= [(800 -752) / 800]100
= 6%
Therefore, the percentage error will be 6%

(ii) factorize 9x^2 - y^2 + 4y - 4
Answer:
(3x - y + 2)(3x + y - 2).
Step-by-step explanation:
9x^2 - y^2 + 4y - 4
= 9x^2 - (y^2 - 4y + 4)
= 9x^2 - (y - 2)^2
= (3x - (y - 2))(3x + (y - 2)
= (3x - y + 2)(3x + y - 2).
What two words describe the result set of a FULL OUTER JOIN minus the INNER JOIN result set in set theory parlance
Answer:
CROSS JOIN (/^\s*symmetric\s*difference\s*$/)
Step-by-step explanation:
Remember, in SQL (Structured Query Language) operations, we can use the CROSS JOIN function to take data from one row of a table in the database and join it with each row of another table.
In other words, the result of FULL OUTER JOIN minus the INNER JOIN of the data set would require a CROSS JOIN operation which would the two different rows into one row.

Which of the following equation represents a horizontal line that passes through the point (1,-2) 1.x=1 2.y=-2 3.y=-2x+1 4.y=x-2
Answer:
(2)
Step-by-step explanation:
The equation of a horizontal line parallel to the x- axis is
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (1, - 2) with y- coordinate - 2, thus
y = - 2 ← is the equation of the line

Find the probability of getting a numbered card when a card is drawn from the pack of 52 cards.
Answer:
[tex]\frac{9}{13}[/tex]
Step-by-step explanation:
1. the formula is: p=(number_of_numbered_cards)/(total_number_of_cards);
2. the number of total numbers of the cards is 52 (according to the condition); the number of the numbered cards is:
4*(10-2+1)=36 (min is '2'; max is '10').
3. after the substitution:
p=36/52=9/13≈0.692

Lin’s family has completed 80% of a trip. They have traveled 400 miles. How far is the trip?
50miles
Step-by-step explanation:
Answer:
500 miles
Step-by-step explanation:
80% is converted to its decimal form 0.8
Multiply 0.8 times "x" which is the unknown total distance of the trip (80% of the total trip) to get 400 because 80% of the trip is 400 miles. Then find x
0.8x = 400
400/0.8 = x
500 = x

How many different phone numbers are possible in the area code 503, if the first number cannot start with a 0 or 1
Answer:
8 X 10^(9)
Step-by-step explanation:
Originally we have 10 digit phone numbers excluding the area code.
For each face value we have these in store: 0,1,2,3,4,5,6,7,8,9 (total 10)
But if we exclude 1 and 0 for the first digit, we are left with 8 digits.
8P1 X .......
In a phone number, digits can repeat so we can choose out of these 10 numbers freely after this.
8P1 X 10P1 X 10P1 X...
Adding the area code while assuming 10P1 is just 10...we get:
1 X 1 X 1 X 8 X 10^(9)
= 8000000000
Very interesting question, thanks for the opportunity!
The number of different phone numbers in the area code 503, if the first number cannot start with a 0 or 1 should be considered as the [tex]8 \times 10^{(9)}[/tex]
Calculation of the number of different phone numbers:Since
we have 10 digit phone numbers that does not include the area code.
So,
For each face value we have these in store:
0,1,2,3,4,5,6,7,8,9 (total 10)
Now
if we exclude 1 and 0 for the first digit, So it left with 8 digits.
So, it be like
8P1 X .......
Likewise
8P1 X 10P1 X 10P1 X...
Now if add this,
1 X 1 X 1 X 8 X 10^(9)
= 8000000000
hence, The number of different phone numbers are possible in the area code 503, if the first number cannot start with a 0 or 1 should be considered as the [tex]8 \times 10^{(9)}[/tex]

9514 1404 393
Answer:
D
Step-by-step explanation:
Solve x = f(y) for y.
x = ∛(y/9) -4
x +4 = ∛(y/9) . . . . . add 4
(x +4)³ = y/9 .. . . . . cube
