Find an ordered pair to represent in the equation vec t = 4 vec u +6 vec v where vec u =(-1,4) and vec v = (3,-2)

Substitute the given vector into the expression for vec t.

Recall that: vec t = 4 vec u +6 vec v

vec t = 4(-1,4)+6(3,-2)

vec t = (4(-1), 4(4)) + (6(3), 6(-2))

vec t = (-4, 16) + (18, -12)

vec t = (-4+18, 16+(-12))

vec t = (14, 16-12)

vec t = (14, 4)

Hence an ordered pair to represent vec t in the equation is (14, 4)

Note that the vec v was assumed. Any other vector coordinate can also be used

Answer: the number of terms of the series is 201 numbers

              the sum of the first 20 terms is 890    

the number of terms of the series is [tex]\frac{805-5}{4}+1=201[/tex]

the series have:

u1 = 5

d = 4

=> u(n) = 5 + 4.(n - 1)

=> u(20) = 5 + 19.4 = 81

so the sum of the first 20 terms is (81 + 5).20/2 = 890

( u1 is the first number of the series, d is the  distance between front and rear numbers, u(n) is the overall term of the sequence, u(20) is the 20th of the series)

Answer:

$100,000

Step-by-step explanation:

Let the total income of the store = [tex]\$x[/tex]

Total spends on salaries = [tex]\frac{1}{4}[/tex] of total income

Total spends on advertising = [tex]\frac{1}{6}[/tex] of total income

Also, we are given that:

Total money paid as salaries = $150,000

To find:

Total spends on advertising ?

Solution:

As per question statement, we can write the following equation:

[tex]\dfrac{1}{4}x =\$150000\\\Rightarrow x =\$150000\times 4\\\Rightarrow x = \$600000[/tex]

Now, as per the given statement, total spends on advertising are:

[tex]\dfrac{1}{6}x =\dfrac{1}{6}\times 600000 = \bold{\$100,000 }[/tex]

Therefore, the answer is $100,000

The independent variable would be

trees used per case of paper

Step-by-step explanation:

Answer:

Number of trees used

Step-by-step explanation:

The number of trees used is the independent variable because it doesn't depend on anything, meaning it isn't changed by other variables. The number of cases of paper would be the dependent variable because it depends on the number of trees used.

Answer:

Please check the attached graph.

Step-by-step explanation:

Note: You did not add the graph; so I am taking a sample graph to clear the concept anyway. Please check the referred graph attached below.

The slope on the graph basically tells us the time rate of change.

The slope can also be termed as:

From the attached graph, taking twp points

Finding the slope between (0, 3) and (-1, 0) using the formula

[tex]\left(x_1,\:y_1\right)=\left(0,\:3\right),\:\left(x_2,\:y_2\right)=\left(-1,\:0\right)[/tex]

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{0-3}{-1-0}[/tex]

[tex]m=3[/tex]

Thus, the slope of the given line on the graph = m = 3

First of all, try to understand the questions then try to make a pair of linear equations. After that make the coefficients of x or y equal in both RFD equations by multiplying them by suitable values then add or subtract them ,in such a way which will terminate any one of the variables. Then find the value of left variable. After that just put the value you have found just now In any of the equations and you'll really get the value of the second variable too.

Answer: Minnie is 9 years old

m = 9

Answer:

A = 112 square feet

Step-by-step explanation:

The perimeter of a rectangular garden is 46 feet.

P = 2(l+b)

46=2(l+b)

23 = (l+b) ....(1)

Let length is l and breadth is b.

The length of the garden is 5 feet less than three times the width.

l = 3b-5 ...(2)

Put equation (2) in equation (1)

23 = (3b-5+b)

23 = 4b - 5

28 = 4b

b = 7 feet

Pu b = 7 in equation (2)

l = 3(7)-5

l = 16feet

Area of a rectangle is given by :

A = lb

A = 16 × 7

= 112 ft²

So, the area of the garden is 112 square feet.

Answer:

123.8 cm

Step-by-step explanation:

well we know that STUV is a parallelogram (given)

so by properties of a parallelogram we know that opposite sides are congruent (in other words equal)

so we have that

VU=TS

and we know that VU=123.8 cm (given)

so TS=123.8

Answer:

14.14 ft long

Step-by-step explanation:

Martin bought a new carpet to cover a room. The carpet is in the shape of a square and it covers an area of 200 ft². How long is the side length of the carpet?

The Area the carpet covers is a square.

Hence, the Area of a square = (Side length)²

From the question, we are given the Area of the square = 200 ft²

Hence:

200 ft² = (Side length)²

We square root both sides.

√200 ft² = √(Side length)²

Side length = 14.142135624 ft

Approximately = 14.14 ft

The side length of the carpet is 14.14 ft long

Answer:

17

Step-by-step explanation:

To find how many notes of Rs. 500 he has, we need to find out the total value of all the Rs. 500 notes.

Total value of Rs. 20 notes = 20 × 40

                                             = 800

Total value of Rs. 1000 notes = 1000 × 20

                                                 = 20 000

Total value of Rs. 500 notes = 29 300 - 800 - 20 000

                                                = 8500

No. of Rs. 500 notes = 8500 ÷ 500

                                   = 17

Rohit has total 17 notes of Rs.500

" Unitary method is the process of finding value of one unit using which we can find the value of other units."

According to the question,

Number of Rs.20 notes = 40

Total amount of Rs.20 = 20 × 40

                                     = Rs.800

Number of Rs.1000 notes = 20

Total amount of Rs.1000 = 20 × 1000

                                         = Rs.20,000

Total amount of Rs.20 and Rs.1000 notes = 20,000 +800

                                                                      = Rs.20,800

Made a payment of Rs.29,300

Left amount of Rs.500 notes = 29,300 -20,800

                                                = Rs.8500

Number of Rs.500 notes = 8500 ÷ 500

                                          = 17 notes of Rs.500

Hence, Rohit has total 17 notes of Rs.500.
