Answer:

$6.37

Step-by-step explanation:

Jane and 3 friends = Jane + another 3 people

= 4 people in total

Total Cost of pizza = $25.48

If 4 people split $25.48 evenly,

Amount each friend has to pay = Total Cost of pizza/Total number of people

= $25.48/4

= $6.37 per friend

Each friend has to pay $6.37 each if $25.48 is splitted evenly amongst them

The total cost for all chains produced in 10 minutes will be $303.14.

The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.

An industrial factory makes 4 ³/₅ yards of chain every minute. Then the rate is given as,

Rate = 4 ³/₅

Rate = 4 + 3/5

Rate = 4 + 0.60

Rate = 4.60 yards per minute

The cost of each yard is $6.59. Then the cost per minute is given as,

⇒ $6.59 x 4.60

⇒ $30.314 per minute

Then the total cost for all chains produced in 10 minutes will be given as,

⇒ $30.314 x 10

⇒ $303.14

Answer:

Step-by-step explanation:

The area of the rectangle is 240 square inches if the length of a rectangle is  8 inches longer than the width. If the ratio of the length to the perimeter is 5:16.

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

It is given that:

The length of a rectangle is  8 inches longer than the width. If the ratio of the length to the perimeter is 5:16

As we know, the two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.

Let l and w be the length and width of the rectangle:

l = 8 + w

w = l - 8

l/P = 5/16  (the length to the perimeter is 5:16)

P is the perimeter of the rectangle.

P = 2(l + w)

l/[2(l + w)] = 5/16

16l = 10(l + w)

8l = 5(l + l - 8)

8l = 10l - 40

2l = 40

l =20 inches

w = 20 - 8 = 12 inches

Area = 20x12 = 240 square inches

Thus, the area of the rectangle is 240 square inches if the length of a rectangle is  8 inches longer than the width. If the ratio of the length to the perimeter is 5:16.

Answer:

The answer is 35%

Step-by-step explanation:

To work out percentage.

(No. Of students / Total Available Seats) * 100

1,344 ÷ 3840 = 0.35

0.35 * 100 = 35%

So, the answer is 35%

Hope this helps! :)

The percentage of the seats in the theater were filled by the 6th graders on the trip will be 35%.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

To Calculate the percent of a number , divide the number by whole number and multiply by 100.

Given that;

Total seats in theater = 3840

And, The students left 2496 seats vacant.

Now,

Find the percentage of the seats in the theater were filled by the 6th graders on the trip as;

Since, Total seats in theater = 3840

And, The students left 2496 seats vacant.

So, Number of students in 6th grade = 3840 - 2496

                                                         = 1344

Hence, The percentage of the seats in the theater were filled by the 6th graders on the trip;

= 1,344 / 3,840  x 100

= 35%

Thus, The percentage of the seats in the theater were filled by the 6th graders on the trip will be 35%.

Answer:

  13√731 ≈ 351.48 cm²

Step-by-step explanation:

When given three sides of a triangle, there are a number of ways that the area may be calculated. Perhaps the most straightforward is the use of Heron's formula.

Where s is the semi-perimeter, the area is given by ...

  A = √(s(s -a)(s -b)(s -c)) . . . . . . . . s = (a+b+c)/2

Here, the value of s is ...

  s = (30 +30 +26)/2 = 43

  A = √(43(13)(13)(17)) = 13√(43·17)

  A = 13√731 ≈ 351.48 . . . . . square centimeters

_____

Additional comments

This triangle is isosceles, so the altitude can be found from the Pythagorean theorem:

  h² +13² = 30²

  h = √(900 -169) = √731

Then the area is ...

  A = (1/2)bh = (1/2)(26 cm)(√731 cm) = 13√731 cm²

__

You can also find one of the angles using the Law of Cosines, then find the area from ...

  Area = (1/2)a·b·sin(C) . . . . . . for any two sides a, b, and enclosed angle C

__

Ultimately, all of these methods are equivalent to Heron's formula.

Answer: 600 eggs

Step-by-step explanation:

Let total number of eggs be x.So, 3% of x were broken and there were 18 broken eggs. We can write this as: 0.03*x =18x=18/0.03x= 600 eggs (answer).

Total number of eggs in the bags are 600.

Percentage is a number or ratio that can be "expressed as a fraction of 100".

According to the question,

Percentage of broken eggs =  3%

Number of broken eggs = 3/100 = 0.03

To calculate the total number eggs,

[tex]\frac{3}{100}[/tex] (x) = 18

      x  = 1800/3

      x = 600.

Hence, the total number of eggs in bags are 600.
