The sum of two numbers is 24 and the quotient is three. what are the two numbers?

Answers

a + b = 24...a = 24 - b
a/b = 3

(24 - b) / b = 3...multiply both sides by b
(24 - b) = 3b
24 = 3b + b
24 = 4b
24/4 = b
6 = b

a + b = 24
a + 6 = 24
a = 24 - 6
a = 18

so ur numbers are 18 and 6

use the counting principle to find the probability of choosing the 8 winning lottery numbers when the numbers are chosen at random from 0 to 9

Answers

Answer: $1/10^8$

Step-by-step explanation:

Here the total numbers are 10 ( 0, 1, 2, 3, 4, 5, 6, 7, 8, 9)

Since, the probability of choosing one number = $(1)/(10)$

Therefore, the probability of choosing 8 numbers =

$(1)/(10)*(1)/(10)* (1)/(10)* (1)/(10)* (1)/(10)* (1)/(10)* (1)/(10)* (1)/(10)*$ ( because there is no replacement)

= $(1)/(10^8)$

The total feasible numbers are: 10*10*10*10*10*10*10*10 = 10^8

The probability is 1/10^8

What are ratio and proportion?

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, Ms. Kraus is 1.75 m tall. When her shadow is 1 m.

Let the shadow of a 265 m tall building be 'x' m.

Therefore by the ratio proportion method.

1.75 : 1 : : 265 : x.

1.75/1 = 265/x.

1.75x = 265.

x = 265/1.75.

x = 151.42 Or 151 m.

PLEASE ANSWER ASPA Using the distance formula, what is the distance of C (-4, -2) and D (3, 5)?

Answers

Answer:

Approximately 9.90 units.

Step-by-step explanation:

The distance formula is:

$d=√((x_2-x_1)^2+(y_2-y_1)^2)$

Let (-4,-2) be x1 and y1, and (3,5) be x2 and y2.

Plug in the numbers:

$d=√((3-(-4))^2+(5-(-2))^2)$

$d=√(7^2+7^2)$

$d=√(2(7)^2)$

$d=7√(2)$

Three equivalent ratio of 48:36

Answers

The three equivalent ratios of 48:36 are 24:18, 16:12 & 12:9.

The given ratio is 48:36

Since we know that,

When we compare two ratios, they are said to be equivalent. To determine whether two or more ratios are equivalent, they can be compared to one another.

Now factorizing these numbers,

48 = 2x2x2x2x3

36 = 2x2x3x3

The common factors of 48 and 36 are, 2, 3 , 4, 6, 9

Hence divide both number by 2 we get ,

24:18

divide both number by 3 we get,

16:12

divide both number by 4 we get ,

12:9

Hence the equivalent ratios are 24:18, 16:12 & 12:9.
