Equation at the end of step 1

STEP

:
Trying to factor as a Difference of Cubes:
2.1 Factoring: 343x3-27
Theory : A difference of two perfect cubes, a3 - b3 can be factored into
(a-b) • (a2 +ab +b2)
Proof : (a-b)•(a2+ab+b2) =
a3+a2b+ab2-ba2-b2a-b3 =
a3+(a2b-ba2)+(ab2-b2a)-b3 =
a3+0+0-b3 =
a3-b3
Check : 343 is the cube of 7
Check : 27 is the cube of 3
Check : x3 is the cube of x1
Factorization is :
(7x - 3) • (49x2 + 21x + 9)
Trying to factor by splitting the middle term
2.2 Factoring 49x2 + 21x + 9
The first term is, 49x2 its coefficient is 49 .
The middle term is, +21x its coefficient is 21 .
The last term, "the constant", is +9
Step-1 : Multiply the coefficient of the first term by the constant 49 • 9 = 441
Step-2 : Find two factors of 441 whose sum equals the coefficient of the middle term, which is 21 .
-441 + -1 = -442
-147 + -3 = -150
-63 + -7 = -70
-49 + -9 = -58
-21 + -21 = -42
-9 + -49 = -58
For tidiness, printing of 12 lines which failed to find two such factors, was suppressed
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Which choice shows the product of 22 and 49
22 • 49 = 968
22 + 49 = 71
(22)(49) = 1078
22 x 49 = 978
Product of 22 and 49 is
(22)(49) = 1078
Option C
Given :
the product of 22 and 49
Explanation :
We need to find which option is correct to find product of 22 and 49
Product mean multiplying the numbers
so we need to multiply 22 and 49
22
49
----------
198
88
-------------
1078
So the product of 22 and 49 is 1078
(22)(49)=1078
Option C is correct

Rosa spent $11.52 on 8 candy necklaces for each of her two friends. How much did each necklace cost?
A:0.72$
B:0.75$
C:0.89$
D:1.72$
Answer:
A. 0.72
Step-by-step explanation:
We take the amount spent on the necklaces and divide that by the amount she bought. So that would be $11.52/8. When we divide this, we get 1.44, and since this is not an option, I went and divided it by the two friends to get 0.72. So I believe A. would be the answer.
The cost for each necklace is given as $0.72.
How to calculate the cost per item?In order to calculate the cost of one item, divide the total cost of items by the total number of items.
It is also called the unit rate of that item.
Total money spent on 8 neckless is $11.52.
The number of friends Rosa has 2.
Then, total number of necklaces is 8 × 2 = 16
Now, the cost of each necklace can be calculated as,
Total cost of necklace ÷ Number of necklace
= $11.52 ÷ 16
= $0.72
Hence, the cost of each necklace for each of the friends is $0.72.

Step-by-step explanation:
A circle is centered at the vertex of an angle, and the angle's rays subtend an arc that is 74.46 cm long. 1/360th of the circumference of the circle is 0.51 cm long. What is the measure of this angle in degrees?
________degrees
Answer:
146°
Step-by-step explanation:
You're given an angle, where the vertex is the center of a circle. This makes the angle's rays two radii of the circle. You are then given the length of 1/360th of the circle, which is .51cm, which is also 1 degree of the circle.
If the arc of the circle between the angle's rays is 74.46 cm. It becomes a division problem:
[tex]\frac{74.46 cm}{.51 cm}[/tex]
After the division, the fraction simplifies to 146, which is 146 segments of .51cm in the arc, and since .51cm is equivalent to 1 degree of the circle, the arc is 146 degrees.

Find the limit. Use l'Hospital's Rule where appropriate. If there is a more elementary method, consider using it. lim x → 0 x 8x 8x − 1
Answer:
1/log8
Step-by-step explanation:
Given the limit of the function
Lim x → 0 x•8^x/8^x − 1
Plug in the value of x
= 0•8^0/8^0-1
= 0(1)/1-1
= 0/0 (indeterminate)
Apply l'hosipitals rule:
Lim x → 0 d/dx(x•8^x)/d/dx(8^x − 1)
= Lim x → 0 (x•8^xlog8+1(8^x))/8^xlog8
Plug in the value of x:
= 0•8^0log8+8^0/8^0log8
= 0•1(log8)+1/1•log8
= 0(log8)+1/log8
= 0+1/log8
= 1/log8
Hence the limit of the function is 1/log8

8. A haircut is $120, how much is a 15% tip? *
Answer:
18
Step-by-step explanation: 120 times 0.15
Answer:
$18
Step-by-step explanation:
To work out 15% using a calculator:
0.15 multiplied by 120 which is 18
To work out 15% without a calculator:
10% of 120 is 12. (Just remove the last number whenever you want to get 10% or add it on as a decimal if it's greater than 0. e.g. 10% of 40 is 4 but 10% of 48 is 4.8)
To add the 5% divide 12 by 2 which is 6.
Add the 10% to the 5% to get the 15%.
12+6=18

Step-by-step explanation:
Researchers studying the relationship between honesty, age, and self-control conducted an experiment on 160 children between the ages of 5 and 15. The researchers asked each child to toss a fair coin in private and to record the outcome (white or black) on a paper sheet, and said they would only reward children who report white. Half the students were explicitly told not to cheat and the others were not given any explicit instructions. Differences were observed in the cheating rates in the instruction and no instruction groups, as well as some differences across children's characteristics within each group.
Required:
Identify the population of interest in the study.
Answer:
The population of interest in this study is:
children between the ages of 5 and 15.
Step-by-step explanation:
In research methodology, the population of interest is the comprehensive group of individuals, institutions, objects, and so forth who possess some common characteristics that are the interest of the researchers. In our example, the researchers are studying the relationship between honesty, age, and self-control. The common characteristic of the group in this case is the age group between the ages of 5 and 15. This characteristic distinguishes the children of this age group from other individuals, institutions, objects, and so forth.

A square tile measuring 4 in. by 4 in. weighs 6 oz. Find the weight, in pounds, of a package of 144 such tiles.
Answer:
[tex]144 \ tiles = 864\ oz[/tex]
Step-by-step explanation:
Given
Dimension: 4 by 4
Weight: 6 oz
Required
Determine the weight of 144 of the tiles
From the question, we have that:
[tex]1\ tiles = 6\ oz[/tex]
Multiply both sides by 144
[tex]144 * 1\ tiles = 6\ oz * 144[/tex]
[tex]144 \ tiles = 864\ oz[/tex]
Josh bought 2 pairs of jeans for $25.60 each and some shirts for $15.30 each. If he spent a total of $112.40,
many shirts did Josh buy?
Answer:
5 shirts
Step-by-step explanation:
2 pairs of jeans $25.60
$112.40-$25.60=$86.80
if each pair of T-shirts cost $15.30
$15.30 times 5=$76.50
$86.80 - $76.50=$10.30
so John bought 5 shirts however he got some many left $10.30
