Answer:

Step-by-step explanation:

Part A: Slope of parallel lines are equal.

4x - 3y - 7 = 0 ⇔ y = [tex]\frac{4}{3}[/tex] x - [tex]\frac{7}{3}[/tex]

m = [tex]\frac{4}{3}[/tex]

y - 3 = [tex]\frac{4}{3}[/tex] ( x + 2 ) ⇔ y = [tex]\frac{4}{3}[/tex] x + [tex]\frac{17}{3}[/tex] ⇔ 4x - 3y + 17 = 0

Part B: Slope of perpendicular lines are opposite reciprocal.

[tex]m_{1}[/tex] × [tex]m_{2}[/tex] = - 1

[tex]m_{1}[/tex] = [tex]\frac{4}{3}[/tex]

[tex]m_{2}[/tex] = - [tex]\frac{3}{4}[/tex]

y - 3 = - [tex]\frac{3}{4}[/tex] ( x + 2 ) ⇔ y = - [tex]\frac{3}{4}[/tex] x + [tex]\frac{3}{2}[/tex] ⇔ 3x + 4y - 6 = 0

Answer:

11/9

Step-by-step explanation:

Multiply the denominator by the whole number

9 × 1 = 9

Add the answer from Step 1 to the numerator

9 + 2 = 11

Step 3

        11/9

The improper fraction which is equivalent to  [tex]1 \frac{2}{9}[/tex]   is [tex]\frac{11}{9}.[/tex]

To convert the mixed number [tex]1 \frac{2}{9}[/tex]  into an improper fraction, you need to multiply the whole number (1) by the denominator (9) and add the numerator (2).

The result becomes the numerator, and the denominator remains the same.

To do this multiply the whole number (1) by the denominator (9):

[tex]1 \times 9 = 9[/tex]

Add the numerator (2) to the result:

[tex]9 + 2 = 11[/tex]

So, the improper fraction equivalent of  [tex]1 \frac{2}{9}[/tex]   is [tex]\frac{11}{9}.[/tex]

The proportion of population in UK to the world population is 64 : 7000 or

0.9 %

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

Given data ,

Let the value of population in UK be = 64 milliom

Let the value of world population be = 7 billion

Now ,

The value of 1 billion = 1000 million

So , the value of 7 billion = 7 x 1000 million

The value of 7 billion = 7000 million

Now , the value of world population is = 7000 million

So , the proportion of population of UK to the world population is given by = value of population in UK : value of world population

And , the equation will be

The proportion of population of UK to the world population is = 64 : 7000

The proportion of population of UK to the world population is = 0.00914

The proportion of population of UK to the world population is = 0.9 %

Hence , The proportion of population in UK to the world population is

64 : 7000 or 0.9 %

Answer2x^2

Step-by-step explanation:

Answer:

Assuming that "x" symbol indicates multiplication, the answer should be 4/3. If you need the decimal form, it would be 1.3. If you want the mixed number form, it'd be 1 1/3.

Step-by-step explanation:

4/5x 1 2/3

4/5 in decimal is 0.8

12/3 in decimal is 4

0.8 multiplied by 4 is 3.2

Therefore 4/5 x 12/3 = 3.2

Answer: 4.50 miles.

Step-by-step explanation:

David hikes 2 1/4 miles in 1/2 hour. To make it easier, we can turn the fractions into decimals.

David hikes 2.25 miles in 0.5 miles.

The ratio of miles hiked to the hours hiked is 2.25 : 0.5. For every 0.5 hours, David hikes 2.25 miles.

To find how many miles David walks in 1 hour, we should multiply the original ratio by 2. 0.5 x 2 = 1, and we need to find how far David walks in 1 hour.

If David hikes 2.25 miles in half an hour, then he will walk 4.50 miles in 1 hour. So the answer is that David will walk 4.50 miles in 1 hour.

Answer:

Interest he earn in the 38 days total = $2458.57

Step-by-step explanation:

As given,

Rate of interest (R)= 4.25% = 0.0425

Principal (P)= $1250

Now,

Simple Interest (S.I) for 20 days = P×R×T

                                                    = 1250×0.0425×10

                                                    = 531.25

⇒Interest for 20 days = $531.25

Now,

Total amount = P + S.I = $1250 + 531.25 = $ 1781.25

As  He then makes a deposit of $450 and makes no transactions for 10 days.

⇒Total amount become = $1781.25 + 450 = $2231.25

Now,

S.I for next 10 days = 2231.25×0.0425×10

                               = 948.28125

⇒Interest for next 10 days = $ 948.28125

∴

Total amount = $2231.25 + 948.28125 = $ 3179.53125

As He withdraws $300 and makes no transactions for 8 days.

⇒Total amount become = $ 3179.53125 - 300 = $ 2879.53125

Now,

S.I for next 8 days = 2879.53125×0.0425×8

                               = 979.040625

⇒Interest for next 8 days = $ 979.040625

a.)

Interest he earn in the 38 days total = Interest in 20 days + next 10 days + next 8 days

                                                                   = $531.25+948.28125+979.040625

                                                                   = $2458.571875 ≈ $2458.57

∴ we get

Interest he earn in the 38 days total = $2458.57
