Answer 1

Answer:16/20

Step-by-step explanation:  

if you divide the two numbers by 4 you have:

16/4=4

20/4=5

(if you divide or multiply both of the numbers with the same number, the ratio will remain the same)

So the two numbers are same

Answer 2
The answer is 16/20 I really hope this helps

Answer:

PQR = 67.4 degrees

Step-by-step explanation:

Here, we want to find the size of PQR

to do this, we proceed as follows

As we can see PR is the opposite while PQ is the hypotenuse

The trigonometric identity connecting the two is the sine

sine is the ratio of the opposite to the hypotenuse

sin Q = 12/13

Q = sin^-1(12/13)

Q = 67.4 degrees

What is the perimeter of the rectangle?​

Answers

Basically that’s it but write it down by yourself

The perimeter of the rectangle is 70cm.

What is perimeter?

Perimeter is the total length of the sides of a two-dimensional shape.

What is the formula for the perimeter of square?

Perimeter of the square is given by

P = 4a

where,

a is the side length of the square.

P is the perimeter of the square.

What is the formula for the perimeter for the rectangle?

Perimeter of the rectangle is given by

P = 2( l + b)

Where,

l is the of the rectangle

b is the breadth of the the rectangle

According to the given question.

We have the perimeter of the square is 20cm.

⇒ 4a = 20

⇒ a = 5cm

⇒ Each side length of the square is 5cm

And a rectangle made of 10 squares.

⇒ length of the rectangle = 5×5 = 25cm

and the breadth of the rectangle = 2 × 5 = 10cm

Therefore, the perimeter of the rectangle = 2(25 + 10) = 2 × 35 = 70cm

Hence, the perimeter of the rectangle is 70cm.

Answers

Answer: The amount of hotdogs you would need to sell in order to reach $300= 80

Step-by-step explanation:

Find how much money is spent per hotdog:

140÷70=2

$140= Amount made by selling 70 Hotdogs

70=Amount of Hotdogs sold already

Dividing 140 by 70 will get you the cost of 1 hotdog. This is due to division being the act of separating something into parts. There are 70 parts (or hotdogs) in this equation so therefore by separating the amount of money made by those selling those parts, the amount per hotdog would be found.

      2. Find the amount of hotdogs it would take to earn a total of $300:

300-140= 160  160÷2= 80

The question asks for a total of $300 to be earnt by selling hotdogs. $140 has already been earnt, therefore a portion of the total amount has been made. By subtracting the amount already made by the total amount of money that is wanted to be earnt, the amount of money needed to reach the $300 is found. The $160 is then divided by the amount of money spent per hotdog ($2). The answer (80) is the amount of hotdogs required to be sold to reach the goal of $300.

Which expression is equivalent to 3 the 5th power?

Answers

Answer:

The expression equivalent to 3 to the 5th power is 3^5.

The number 3 raised to the 5th power is represented through the expression 3 ^ 5, which means that the number 3 is multiplied by itself 5 times (3x3x3x3x3), which results in the number 243, which is can be corroborated by the following calculations:

3x3 = 9

9x3 = 27

27x3 = 81

81x3 = 243

The solution is: The expression equivalent to 3 to the 5th power is 3^5.

Here, we have,

The number 3 raised to the 5th power is represented through the expression 3 ^ 5,

Find the value of x in the figure. 57 x+23 DUE AT 3PM 2/1 PLZ HELP WITH STEPS

Answers

Answer:

x = 100

Step-by-step explanation:

Since the two sides need to equal 180 degrees, we would have this as our formula: x + 23 + 57 = 180

23 + 57 is 80, and we subtract 80 from 180 to get 100 as our answer.

The required value of the variable x is 100, which is determined by the property of the supplementary angles.

As we know that supplementary angles are defined as when pairing of angles addition to 180° then they are called supplementary angles.

Here, the two sides must equal 180 degrees.

As per the property of supplementary angle, it can be written as:

x + 23 + 57 = 180

Apply the addition operation,

x + 80 = 180

x = 180 - 80

Apply the subtraction operation to get,

x = 100

Therefore, the required value of the variable x is 100.
