Answer:

a. 1 200 000 km

b. 0.000 773 cm

c. 67 500 000 000 km²

d. 0.000 000 016 cm²

Step-by-step explanation:

a. Calculate the ACTUAL distance, in km, between two places which are 16 cm apart on the map.

Since the scale is 1 : 75000 that is 1 cm : 75000 km, we want to find the actual distance of 16 cm on the map. Let x be the actual distance in km.

So, 1 cm : 75000 km = 16 cm : x km

So, 1 cm/75000 km = 16 cm/x km

Thus x km = 16 cm × 75000 km/1 cm = 1 200 000 km

(b) Calculate length of a road on the map which is 0.58 km.

Let y be the length of road on the map. So, using our scale

1 cm : 75000 km = y cm : 0.58 km

So, 1 cm/75000 km = y cm/0.58 km

Thus y cm = 0.58 km × 1 cm/75000 km = 0.000 773 cm

(c) Calculate, in km², the ACTUAL area of a lake which is 12 cm2 on the map.

Since the scale is 1 : 75000 , the scale for the area would be the square of this. So, 1² : 75000² = 1 : 5 625 000 000 which is 1 cm² : 5 625 000 000 km²

Let z be the actual area of the lake.

So,  1 cm² : 5 625 000 000 km² = 12 cm² : z km²

So, 1 cm²/5 625 000 000 km² = 12 cm²/z km²

Thus z km² = 12 cm² × 5 625 000 000 km²/1 cm² = 67 500 000 000 km²

(d) Calculate the area of a play field on the map which has has an actual area of 90 km².

Let a represent the area of the play field on the map. Using our scale for the area,

1 cm² : 5 625 000 000 km² = a cm² : 90 km²

So, a cm² = 90 km² × 1/5 625 000 000 km² = 0.000 000 016 cm²

2(x² – 4x – 12)

Step-by-step explanation:

(2x+4)(x–6) →

2(x+2)(x–6) →

2(x(x–6) + 2(x–6)) →

2(x² – 6x + 2x – 12) →

Step-by-step explanation:

Answer:

m<A = 72 degrees

m<B = 108 degrees

Step-by-step explanation:

For the parallelogram ABCD

The sum of the opposite angle will be 180 degrees

Hence <A + <B = 180 and m<A = m<C

5y - 3 = 3y + 27

5y - 3y = 27 + 3

2y = 30

y = 30/2

y = 15

Get m<A

m<A = 5y - 3

m<A = 5(15)-3

m<A = 75 - 3

m<A = 72 degrees

Get m<B

From the equation above;

m<B = 180 - m<A

m<B = 180  - 72

m<B = 108degrees

Answer:

1 0 2  +  1 6 0

Step-by-step explanation:

Multiply the numbers

(10*16) +10x xp)

(160) +(10x xp)

Combine exponents

(160) + (10xxp)

160 + 10 [tex]x^{2}[/tex] p

Eliminate redundant parentheses

(160) + (10xxp)

160 + 10 [tex]x^{2}[/tex] p

Rearrange terms

160 + 10 [tex]x^{2}[/tex] p

1 0 2  +  1 6 0

Answer:

hey i am also on this problem did you ever figure it out

Answer:

d = 3 and d = 3/4

Step-by-step explanation:

This is a quadratic eqution.  Let's use the quadratic formula to solve it.

If ax^2 + bx + c = 0, then:

      -b ± √(b^2 - 4ac)

x = ---------------------------

                 2a

With a = 4, b = -15 and d = 9, we have:

      -(-15) ± √(225 - 4(4)(9) )        15 ±√81         15 ±9

d = ------------------------------------ = -------------- = -------------- = 24/8 and 6/8

                      2(4)                              8                   8

Simplifying these results, we get d = 3 and d = 3/4

Answer:

$22

Step-by-step explanation:

Given data

Principa= $20

rate= 10%

time= 1 year

The simple interest expression is given as

A= P(1+rt)

substitute

A= 20(1+0.1*1)

A= 20*1.1

A= $22

Hence the amount after 1 year is  $22

Answer:

The amount in the account after 3 years is $672.00

Step-by-step explanation:

Here, we want to use the compound interest formula

A = P(1 + r/n)^nt

A is the amount in the account after the given time

P is the principal which is the deposit amount = $600

r is the interest rate = 3.85% = 3.85/100 = 0.0385

n is the number of times interest is compounded yearly (since it is annually, n = 1)

t is the time in years = 3

Substituting these values;

A = 600(1 + 0.0385/1)^(3 * 1)

A = 600(1.0385)^3

A = $672

Five tulips for 3.00 dollars

Answer:

7 tulips for $4.00

Step-by-step explanation:

you have 5 tulips for 3.00 dollars and 7 tulips for only 4.00 is a better deal because you just add 1 more dollar.

Given:

The table of values for the function f(x).

To find:

The equation for the function f(x).

Solution:

From the given table it is clear that the function passes through the point (0,5) and (1,8). So, the equation of the linear function that passes through the (0,5) and (1,8) is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-5=\dfrac{8-5}{1-0}(x-0)[/tex]

[tex]y-5=\dfrac{3}{1}x[/tex]

[tex]y=3x+5[/tex]

The function notation is:

[tex]f(x)=3x+5[/tex]

Therefore, the required function is [tex]f(x)=3x+5[/tex].
