Answer:

t12= -8

Step-by-step explanation:

t3

a+2d=10 (1)

t10

a+9d=-4. (2)

From (1)

a=10-2d. (3)

Sub into (3) into equ (2)

a+9d=-4

10-2d+9d=-4

10+7d=-4

7d=-4-10

7d=-14

Divide both sides by 7

d=-14/7

d= -2

10=a+2d

10=a+2(-2)

10=a-4

10+4=a

14=a

a=14

t12=a+11d

= 14+11(-2)

=14-22

= -8

t12= -8

Answer:

Each pendant = 3.60

Step-by-step explanation:

3 necklaces made of beads and pendants

The total is 20.10

20.10 = 3( beads + pendant)

Distribute

20.10 = 3 beads + 3 pendant

The total for the beads is 9.30

Replace the 3 beads  with 9.30

20.10 = 9.30+ 3 pendant

Subtract 9.30 from each side

20.10-9.30 = 9.30+ 3 pendant - 9.30

10.80 = 3 pendant

Divide each side by 3

10.80/3 = 3 pendant/3

3.60 = pendant

s = number of states visited

d = number of days

Answer:

The probability that the outcome of the roll is an even sum or a sum that is a multiple of 3

P( E∪F)  [tex]= \frac{24}{36}[/tex]

Step-by-step explanation:

Given Each number cube has sides numbered 1 through 6

Two distinct number cubes are rolled together

Total number of exhaustive cases n(S) = 36

Let 'E' be the event of getting sum is even

n(E) = {(1,3),(1,5), (2,2),(2,4),(2,6),(3,1),(3,3),(3,5),(4,2),(4,4), (4,6),(5,1),(5,3),(5,5),(6,2),(6,4),(6,6)} = 17

[tex]P(E) = \frac{n(E)}{n(S)} = \frac{17}{36}[/tex]

Let 'F' be the event of getting sum that is a multiple of '3'

n(F) = {(1,2),(1,5),(2,1),(2,4),(3,3),(3,6),(4,2),(4,5),(5,1),(5,4),(6,3),(6,6) = 12

[tex]P(F) = \frac{n(E)}{n(S)} = \frac{12}{36}[/tex]

n((E∩F) = {(2,4),(3,3),((4,2),(5,1),(6,6)} =5

[tex]P(En F) = \frac{n(En F)}{n(S)} = \frac{5}{36}[/tex]

The probability that the outcome of the roll is an even sum or a sum that is a multiple of 3

P( E∪F) = P(E) + P(F) - P( E∩F)

            [tex]\frac{17}{36} +\frac{12}{36} - \frac{5}{36} = \frac{24}{36}[/tex]

Answer:

[tex]x = \frac{k + c}{4}[/tex]

Step-by-step explanation:

Given:

[tex]4x - c = k[/tex]

Solve for:

[tex]x[/tex]

Solution:

(1) Let's move all of components that do not contain [tex]x[/tex] (our target) to the right side (notice the change of sign of [tex]c[/tex] from negative to positive):

[tex]4x = k + c[/tex]

(2) Let's divide both sides of equation by 4:

[tex]\frac{4x}{4} = \frac{k + c}{4}[/tex]

(3) Now, we simplify the left side:

[tex]x = \frac{k + c}{4}[/tex]

This is the solution.

Hope this helps!

Answer:

A: No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100

Step-by-step explanation:

c = child bike

a = adult bike

Child bike requirement:

4 hours build time

4 hours test time

Adult bike requirement:

6 hours build time

4 hours test time

Available Building time per week ≤ 120 hours

Available Testing time per week ≤ 100 hours

Therefore, company's work schedule is;

Building:

4c + 6a ≤ 120

Testing:

4c + 4a ≤ 100

Combined:

4c + 6a ≤ 120 and 4c + 4a ≤ 100

Building 20 Child bike and 6 adult bike in a week:

4(20) + 6(6) ≤ 120 and 4(20) + 4(6) ≤ 100

80 + 36 ≤ 120 - - - - 80 + 24 > 100

Therefore Building 20 Child bike and 6 adult bike in a week is not feasible.

Answer:

Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100

We have that

The Matrix A  is a singular square matrix and because its determinate is zero. No the Matrix A is inveritible because its determinant is not equal to zero.

Option E is correct

From the question we are Given the matrix:

[tex]A= \begin{bmatrix}6 & -4 \\-9 & 6\end{bmatrix}[/tex]

Invertible Matrix

In linear algebra, an n-by-n square matrix A is called invertible if there exists an n-by-n square matrix B such that

[tex]AB=BA=I_n[/tex]  

where In denotes the n-by-n identity matrix and the multiplication used is ordinary matrix multiplication.

Invertible Matrix characteristics does not apply to singular square matrix, A square matrix is singular if and only if its determinant is zero

Generally the determinate of Matrix A is given as

[tex]A= \begin{bmatrix}6 & -4 \\-9 & 6\end{bmatrix}[/tex]

[tex]D=(6*6)-(-4*-9)\\\\D=0[/tex]

In conclusion

The Matrix A is a singular square matrix and because its determinate is zero.

So, No the Matrix A is inveritible because its determinant is not equal to zero.

Option E is correct

answer answer

Step-by-step explanation:

First you need to find the area of the base and then multiply that by the height. The base of the cylinder is equal to pi times the radius squared or πr² which in this case is π·2². We then multiply the base times the height which gives us 10·π·2^2. I will let you simplify the result on your own.

Answer:

£2,450

Step-by-step explanation:

What we want to do here is calculate the total amount spent on his birthday in £

We already have some costs in pounds, it is the costs not in pounds we are converting.

Flights already in pounds, no conversion

Hotel $105 per night at 14 days

Total here is 14 * 105 = $1470

Wifi cost at $4 per day for 13 days

Total here is 13 * 4 = $52

Total amount spent in dollars alone is $1470 + $52 = $1522

We try and covert this to pounds

$1.45 = £1

$1522 = £x

We simply cross multiply at this point

x = 1522/1.45 = 1049.65 which is approximately £1050

Total amount spent in £ is thus 1050 + 1400 = £2,450

Answer:

£2449.65

Step-by-step explanation:

105 × 14 = $1470

1470 ÷ 1.45 = £1013.79

13 × 4 = $52  

52 ÷ 1.45 = £35.86

£1013.79 +  £35.86 = £1049.65

£1049.65 + 1400.00 = £2449.65

The total cost was £2449.65

Step-by-step explanation:

b+43˚=90˚

subtract 43˚ from both sides of the equation

b=47˚

3x+33˚=180˚ (because it's a straight angle)

subtract 33˚ from both sides

3x=147˚

divide both sides by 3

x= 49˚

Answer:

525 mm

Step-by-step explanation:

x<7, The third option

Step-by-step explanation:

-1.1x+6.4>-1.3

We are trying to isolate x so we can move all the constant to one side.

-1.1x>-1.3-6.4

-1.1x>-7.7

Lastly, we need to divide both sides by -1.1.

-1.1x>-7.7/-1.1

Note that if you multiply or divide both sides of an inequality by a negative, then you need to flip the sign.

x<7

What type of sequence does this scenario represent, and why?

✔ arithmetic; the sequence has a common difference

If the pattern of the sequence continues, how many guests will the restaurant have on its 14th night?  

✔ 360

This example doesn't accurately depict arithmetic because the succession has a common difference. The restaurant will host 360 customers on its fourteenth night if the pattern of the series holds.

Arithmetic sequences always add or subtract the same amount to go from one term to the next. Finding the difference between any AP phrase and its predecessor will reveal the common difference, indicated by the letter "d."

An arithmetic sequence's nth term is determined by, Formula an = a1 + (n - 1)d. The common difference, or d, is the difference between any two consecutive terms in an arithmetic series; it can be calculated by deducting any pair of terms starting with a and an+1.

an = 100 + (14 - 1)20.

an = 360

The restaurant will host 360 customers on its fourteenth night if the pattern of the series holds.
