If a package of gift cards has a total value of $1050 how much does the average set of 2 gifts card price at if there are 15 in a group?
Answer:
$140
Step-by-step explanation:
If a package of gift cards has a total value of $1050, the total price for 2 gift cards will be 2×$1050 = $2100
If there are 15 in an average set of 2 gift cards, the average cost of the two gift cards will be expressed as;
Total price of 2gift cards/amount of card per group.
Average cost of of 2 gift cards = $2100/15
= $140
Hence the average cost of 2gift cards if there are 15 in a group is $134

Sally hopes to buy a 10 - kayak for $15,000. Describe all the numbers that when round to the nearest hundred are 15,000
Answer:
All the numbers ranging from 14,500 to 15444 would be rounded to 15000
Step-by-step explanation:
All the numbers ranging from 14,500 to 15444 would be rounded to 15000.
How this is possible.
1) all the numbers from 0-4 are not counted as the next number when rounded off.
2) all the numbers from 5-9 are counted as the next number when rounded off.
Example Suppose we have numbers from 15- 19.
These numbers can be rounded off to 20
But numbers from 10-14 would never be rounded off to 20 instead they are rounded as 10.
Same happens in the hundreds case.
If we have numbers from 450 - 499 they can be rounded as 500
And numbers from 400 - 444 cannot be rounded as 500 but the number 445 may be rounded as 450 . When we carry 5 from units place and replace it as 450 then again 450 can be rounded to 500.
Same happens with 15000 but when are rounding nearest hundred not ten.
Thus all the numbers ranging from 14,500 to 15444 would be rounded to 15000.
round 737.88 to the nearest tenth place?
Answer:
737.9
Step-by-step explanation:
8 is the hundredth place in 737.88, and 8 rounds up. So, the answer is 737.9
Answer:
737.9
Step-by-step explanation:
When we round something to the nearest ___ place, we want to look to the value to the right of it.
Since we're rounding it to the nearest tenths place, we want to look at the value to the right of it - the hundredths place.
The number in the tens place will be one more if the hundredths place is 5 or greater. It will remain the same if the hundredths place is below 5.
8 is greater than 5. This means the tens place will round up to 9.
So 737.9.

Find an expression for the number of colored border tiles needed for any N x N square center.
Answer:
8N - 4 border tiles.
Step-by-step explanation:
There are 4 border tiles in each corner and between the tiles there are N-2 tiles along the 4 sides.
So the number of border tiles
= 4+ 4(N - 2)
= 4 + 4N - 8
= 8N - 4.
A woman making $3000 per month has her salary reduced by 10% because of sluggish sales. One year later, after a dramatic improvement in sales, she is given a 20% raise over her reduced salary. Find her salary after the raise.
Answer:
$3240 a month
Step-by-step explanation:
First, find her reduced salary:
3000(0.9)
= 2700
Then, find her salary after the raise:
2700(1.2)
= 3240
So, her salary after the raise is $3240 a month

3. Two fair dice are thrown once, find the probability of getting a total score greater than 5
Answer:
26/36
Step-by-step explanation:
The probability of something = the amount of favourable outcomes/total possible outcomes.
The total number of dice combinations is 36 (6x6).
In this case there are more outcomes more than 5 than less than 5 so for the sake of simplicity we are going to find the number of outcomes less than 5 and then find the inverse.
There are only 10 possible dice combos which add to totals 5 or under:
1,1 1,2 2,1 1,3 3,1 1,4 4,1 2,2 2,3 and 3,2
That means there is a 10/36 probability of getting a total score less than 5 so to get the probability of getting more than 5, we just do 36/36 - 10/36 (because all probabilities add to 1)
Therefore there is a 26/36 probability that the toatals will add to greater than 5.
Alternatively you could also draw up a possibilities table and count the favourable outcomes.
Hope this helped!
Answer:
13/18.
Step-by-step explanation:
The favourable outcomes are (1,5) (1,6) (2,4) (2,5) (2,6) (3,3) (3,4) (3,5) (3,6) (4,2)(4,3) (4,4) 4,5) (4,6) 5,1) (5,2) 5,3) (5,4) (5,5) (5,6 )(6,1) to (6,6).
= total of 26.
As the total of all possible outcomes is 36 the answer is 26/36
= 13/18.

Jamie invests part of $10,000 at 9% annual interest and the rest at 8%. If his annual income from
these investments is $860, how much does he invest at 8%?
Answer:
$4000
Step-by-step explanation:
Assuming a = money invested at 9%
Assuming b = money invested at 8%
then we can form am equation from the question given
1) a + b = $10000, also
0.09a + 0.08b = $860 -> multiply by 100
2) 9a + 8b = $86000
Next we try to solve both equations simultaneously. We multiply both the left hand side and the right hand side of the first equation by 8. We have
3) 8a + 8b = $80000, now we subtract 3 from 2
9a + 8b = $86000
-8a - 8b = -$80000
a = $6000.
Then, we plug this in any of the first 2 equations, to get b
9 * $6000 + 8b = $86000
$54000 + 8b = $86000
8b = $86000 - $54000
8b = $32000
b = $32000/8
b = $4000.
Therefore, he invested $4000 at 8%

During its first year in business, Alice's restaurant shows a loss of $12,000. During its second year, the restaurant makes a profit of $23,200, and during its third year, the restaurant shows a loss of $1,200. What is the net profit of the restaurant during its first three years in business?
Answer:
$10,000
Step-by-step explanation:
-12,000+23,200-1,200= 10,000
The profit of the restaurant during it's first 3 years is 9800 dollars.
What is profit and loss ?When the amount of money we get is more than what we have invested is more we have profit and when the amount of money we get is less than what we have invested we have loss.
Let us assume Alice start with a net profit or or of 0 dollars.
During its first year in business, Alice's restaurant shows a loss of 12,000 dollars.
∴ He is in loss of (0 - 12000) dollars which is
= - 12000 dollars.
During its second year, the restaurant makes a profit of 23200 dollars.
∴ His net profit is
= ( -12000 + 23000 ) dollars.
= 11000 dollars.
During its third year, the restaurant shows a loss of 1200 dollars so his ne profit is
= ( 11000 - 1200 ) dollars
= 9800 dollars.

Which inequality is true?
O A n-3>1
B. 9n> 27
c. 9/3n> 1
O D. N+7<10
Answer:
c.
Step-by-step explanation:
Let A and B be symmetric nxn matrices. For each of the following, determine whether the given matrix must be symmetric or could be nonsymmetric.a) C = A + Bb) D = A^2c) E = ABd) F = ABAe) G = AB + BAf) H = AB-BA
The matrices C, D, F, and G are symmetric while matrix H is skew-symmetric and matrix E is non-symmetric.
A matrix is an array of elements(numbers) in a peculiar order. A matrix with m rows and n columns is said to be of order m × n.
As it is known that [tex](A + B)^t = A^t + B^t[/tex] and [tex](AB)^t = B^t A^t[/tex] for any n × n matrices A and B.
Also, if matrices A and B are symmetric, then
[tex]A^t = A[/tex] and [tex]B^t = B[/tex].
a) Given that
C = A + B
Take the transpose of matrix C,
[tex]C^t = (A + B)^t[/tex]
[tex]= A^t + B^t \\= A + B = C[/tex].
Hence, matrix C is symmetric.
b) Given that
D = A²
Take the transpose of matrix D,
[tex]D = (A^2)^t[/tex]
[tex]= (AA)^t \\= A^t A^t \\= AA \\= A^2 = D[/tex].
Hence, matrix D is symmetric.
c) Given that
E = AB
Let's take an example,
A = [tex]\left[\begin{array}{cc}1&2&2&1\end{array}\right][/tex] and
B = [tex]\left[\begin{array}{cc}1 &-1 &-1&2\end{array}\right][/tex]
So,
E = AB
[tex]=\left[\begin{array}{cc}1&2&2&1\end{array}\right] \times \left[\begin{array}{cc}1 &-1 &-1&2\end{array}\right]\\= \left[\begin{array}{cc}-1&3&1&0\end{array}\right][/tex]
Clearly, matrix E is non-symmetric.
d) Given that
F = ABA
Take the transpose of matrix F,
[tex]F^t = (ABA)^t[/tex]
[tex]= A^t B^t A^t\\ = ABA = F[/tex].
Hence, matrix F is symmetric.
e) Given that
G = AB + BA
Take the transpose of matrix G,
[tex]G^t = (AB + BA)^t[/tex]
[tex]= (AB)^t + (BA)^t \\= B^t A^t + A^t B^t \\= BA + AB = G[/tex].
Hence, matrix G is symmetric.
f) Given that
H = AB-BA
Take the transpose of matrix H,
[tex]H^t = (AB - BA)^t[/tex]
[tex]= (AB)^t - (BA)^t \\= B^t A^t - A^t B^t \\= BA - AB = -H[/tex].
Hence, matrix H is skew-symmetric.
Thus, the matrices C, D, F, and G are symmetric while the rest are not.

Express the following vector in the form v vi+V2j+ v3k 3u -v if u (3,5,-8) and v (2,-5,7)
Answer:
7i+20j-31kStep-by-step explanation:
Given the vectors u (3,5,-8) and v (2,-5,7), they can also be written as;
u = 3i+5j-8k
v = 2i-5j+7k
To express the vector 3u - v in vector form, first let us find the vector 3u;
3u = 3(3i+5j-8k)
3u = 3(3i)+3(5j)-3(8k)
3u = 9i+15j-24k
Subtract v from the resulting vector.
Since v = 2i-5j+7k
3u - v = 9i+15j-24k - (2i-5j+7k)
3u-v = 9i+15j-24k -2i+5j-7k
collect the like terms
3u-v = 9i-2i+15j+5j-24k-7k
3u-v = 7i+20j-31k
Hence the vector 3u-v in the form v = vi+V2j+ v3k is 7i+20j-31k
