The real number that should be subtracted from - 5 to get 0 is -5 (option b).

A real number is a quantity that can be written as an infinite decimal expansion. A real number is made up of both rational numbers and irrational numbers.

Rational numbers are numbers that can be expressed as a fraction of two integers. An example is 5, -5.  Irrational numbers cannot be expressed as a fraction of two integers. An example is 22/7, 1/3.

In mathematics, the following rules exist:

Answer:

Area = 192.5 ft.²

Step-by-step explanation:

By splitting the shape in 2, we can find the area much simpler.

Starting with the parallelogram (on the left), the area formula is A = b × h.

b (base) = 11 ft.

h (height) = 7 ft.

A (area) = (11 ft.)(7 ft.)

A = 77 ft.² (save this for later)

Then, the trapezoid's (on the right) area formula is A = [(a + b) ÷ 2] × h.

a (first base) = 8 ft.

b (second base) = (20 - 7) = 13 ft.

h (height) = 11 ft.

A = [(8 ft. + 13 ft.) ÷ 2] × 11 ft.

A = [(21 ft.) ÷ 2] × 11 ft.

A = (10.5 ft.) × 11 ft.

A = 115.5 ft.²

Now, bringing back the first area, we can add them together to find the total:

A = 77 ft.² + 115.5 ft.²

A = 192.5 ft.²

Answer:

Step-by-step explanation:

Colin paid the loan at a ten percent annual interest rate.

Simple interest is the form of interest calculation in which the principal amount remains the same for the entire duration for which the loan is taken.

It is also assumed that Colin will repay $35 per month for the next two years.

We must calculate a simple interest rate on Colin's borrowings.

As a result, Colin's total payment to his parents for two years is $35.

We are required to find simple interest rate on Colin's borrowings

Therefore, total amount paid by Colin to his parents= 35$ for 2 years

        =35*24=840

The amount paid by Colin is principal + interest

Thus, the simple interest amount= 840-700=140$

We know that the simple interest formula is principal*rate*time/100.

We know that the simple interest is 140, the principal is 700, the time is two years, and we need to find the rate of interest.

SI= P*R*T/100

140= 700*R*2/100

140/7*2=R

R=140/14=10

Therefore, The Rate of interest on which Colin paid the loan is 10 per cent per annum

Based on the fact that the widow got an exemption on homestead tax, the amount that the owner would pay in property taxes is $3,471.20.

The widow received a homestead tax exemption of $25,000 on the property.

The amount to be paid in property tax is:

= (8.8 + 9.3 + 6.5) / 1,000 x (185,000 - 25,000)

= 21.7/1,000 x 160,000

= $3,471.20

In conclusion, the property tax to be paid is $3,471.20.

The Perimeter of rectangle 3cm 5cm is 16 cm.

In geometry, a rectangle is a plane figure of four sides having four angles of 90 degree. A rectangle has different length and breadth.

Some important formulas for rectangle :

Perimeter is define as the distance around all the edges of a shape. In case of rectangle perimeter is the distance of all 4 edges i.e. 2 lengths and 2 breadth .

Thus , perimeter of rectangle = ( 2 × length ) + (2 × breadth)

                                                 = 2 ( length + breadth )

In the given question,

length of rectangle =  3cm

breadth of rectangle = 5cm

therefore, perimeter of rectangle = 2(3+5) = 16cm

Hence, The Perimeter of rectangle is 16 cm.

The solution to the system of equations is x = -8/7, y = 4/7 and z = -2/7

The system of equations is given as

2x - y + 2z = -6

-3y + z = -2

2x - 3z = -4

Subtract 2x - 3z = -4 from 2x - y + 2z = -6

This is represented as

(2x - y + 2z = -6) - (2x - 3z = -4)

This gives

- y + 5z = -2

Multiply - y + 5z = -2 by 3

-3y + 15z = -6

Subtract -3y + 15z = -6 from -3y + z = -2

This is represented as

(-3y + z = -2) - (-3y + 15z = -6)

This gives

-14z = 4

Divide by -14

z = -2/7

Substitute z = -2/7 in - y + 5z = -2

- y - 5 * 2/7 = -2

This gives

- y - 10/7 = -2

Rewrite as:

y = 2 - 10/7

Evaluate

y = 4/7

Substitute z = -2/7 in 2x - 3z = -4

2x - 3 * 4/7 = -4

This gives

2x - 12/7 = -4

So, we have:

2x = 12/7 - 4

Evaluate

2x = -16/7

Divide by 2

x = -8/7

Hence, the solution to the system of equations is x = -8/7, y = 4/7 and z = -2/7

The scale drawing which is equal to 9 yards in real time is 12 cm.

Given that 4cm on the scale, drawing is equal to 3 yards in real-time

we have to find the scale drawing which is equal to 9 yards in real-time.

Let the scale drawing be 'x'

Now it can be written as

4 cm ------ 3 yards

x cm ------- 9 yards

Now we can divide this as

4/x = 3/9

By cross multiplication, we get

4 * 9 = 3 * x

x = 4 * 9 / 3

x = 12

Therefore, the scale drawing which is equal to 9 yards in real time is 12 cm.

The number of black-and-white is 60 and the number of color copies is 8.

Let b = the number of black-and-white.

Let c = the number of color copies.

The equation will be:

b + c = 68

0.08b + 0.15c = 6

Multiply equation I by 0.08

Multiply equation ii by 1.

0.08c + 0.08c = 5.44

0.08b + 0.15c = 6

Subtract

0.07c = 0.56

c = 0.56/0.07

c = 8

Since b + c =68

b= 68 - 8 = 60

Therefore, the number of black-and-white is 60 and the number of color copies is 8.
