Answer:

667 bagels in 23 hours

29 bagels per hour

Step-by-step explanation:

We first find the unit rate in bagels per hour.

(290 bagels) / (10 hours) = 29 bagels/hour

Now we find the number of bagels made in 23 hours.

23 hours * 29 bagels/hour = 667 bagels

Answer:

Answer below

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

The perimeter of the rectangle is 70cm.

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

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.

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.

Answer:

x-1

Step-by-step explanation:

Answer:

x - 1

Step-by-step explanation:

4(x+5)-3(7+x)

4( x + 5) = 4x + 20

4x+20-3(7+x)

-3(7 + x) = -21 - 3x

4x+20-21-3x

4x + 20 - 21 - 3x = x-1

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

Step-by-step explanation:

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.

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

Answer:

49.53 nautical miles

Step-by-step explanation:

57 converted to nautical miles would be 49.53

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.
