What are arithmetic operations?

The arithmetic operations are the fundamentals of all mathematical operations. The example of these operators are addition, subtraction, multiplication and division.

The total distance covered in 8 hours is 504 miles.

Then in one hour, distance covered is given as below,

⇒ Number of miles ÷ Number of hours

⇒ 504 ÷ 8 = 63

Then, the distance covered in 13 hours is given as,

⇒ Unit distance in 1 hour × Number of hours

⇒ 63 × 13 = 819

Hence, the miles travelled in 1 hour is given as 819 miles.

Find the slope y intercept and x intercept and write in y=mx+b

Answers

Answer:

Slope (m) = (-1/6)

y-intercept (b) = (-3.5)

x-intercept (x) = (-21)

y = mx + b

y = (-1/6)x - 3.5

Explanation:

y = (-1/6)x - 3.5

0 = (-1/6)x - 3.5

3.5 = (-1/6)x

(-1/6)x * -6 = x

3.5 * -6 = -21

-21 = x

No matter how long they rent for, they have to pay at least 20. Any additional hour is 10. But since it says “part of an hour” that makes this really easy.
1) $30 (the first hour is 20, the second hour is 10 even though they didn’t use the full hour completely)
2)$30 (same situation as 1)
3)$40 (20+10+10)
4)$50 (20+10+10+10 even though that additional hour was only 1 min)
5) Below five hours and above three hours. If you’re spending $50 you rented it within at least four hours. I hope that makes sense

What is proportion?

In general, the term "proportion" refers to a part, share, or amount that is compared to a total.

According to the concept of proportion, two ratios are in proportion when they are equal.

Two ratios or fractions are equal when an equation or a declaration to that effect is utilised.

A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.

Given:

when x= 2/3, y=6.

Using constant proportionality

y = kx

k= y/x

k = 6 / (2/3)

k = 6 x 3/2

k = 9

Now, k= y/x

9 = y/ ([tex]10\frac{1}{3}[/tex])

9 = y / (31/ 3)

y = 9 x 31/3

y = 93

Hence, the value of y is 93.

Find 4ab when (a+b)=15 and (a-b)=12

Answers

a + b = 15 ..... eq 1
a – b = 12 ...... eq 2

So a = 15 – b
Substitute in eq 2 :

15 – b – b = 12
15 – 2b = 12
–2b = 12 – 15
b = 1.5

So a = 15 – 3/2 = 13.5

4ab = 4 x 13.5 x 1.5 = 81

Answer:

Step-by-step explanation:

here,

(a+b)=15 -------(1)

(a-b)=12 -------(2)

Equating the equation (1) and (2)

a + b = 15

a - b = 12

(b gets cancelled having opposite signs)

or, 2a = 27

or, a = 27÷2

a = 13.5

then, putting value of a in equation (1)

a+b=15

or, 13.5 + b=15

or, b=15-13.5

b=1.5

lastly,

4ab = 4×13.5×1.5

= 81
