Answer:

  813 N/m²

Step-by-step explanation:

The units of pressure tell you it is found by dividing force by area. Here, we need to convert the units of the given area so we can express the pressure appropriately.

__

  pressure = force / area

  pressure = (61 N)/(750 cm² × ((1 m)/(100 cm))²) = (61 N)/(0.0750 m²)

  pressure ≈ 813 N/m²

Answer:

7.5 feet

Step-by-step explanation:

Hello there.

1. We know that the scale drawing is 0.75 inches long.

2. If 1 whole inch on the map is equivalent to 10 feet in real life, then how much feet in real life would be 0.75 inches on the map?

0.75 is equivalent or equals to 3/4 as a fraction.

Multiply 3/4 with 10 feet to get 7.5 feet.

Hope this helped!

Step-by-step explanation:

Y is directly proportional to X" can be rewritten as a mathematical expression of the form Y = KX

"K" is the constant of proportionality and must be determined from the initial information.

If Y = 2/3 when X=1/12means 2/3=1/12

K = 2/3÷1/12 = 8

Now that we know the value of K, we can use it to calculate the value of Y when X=1/2

Y = (8)(1/2) = 8/2=4

Y=4

Given that C varies directly as N, the value of Calories C when the number of ounces N is increased to the given value is 684 calories.

Proportional relationships are relationships between two variables where their ratios are equivalent.

Direct variation equation is a linear equation in two variables.

It is expressed as;

a ∝ b then a = kb

Where k is the proportionality constant.

Given the data in the question;

Since Calories C and Number of ounces N varies directly, we find their proportionality constant.

a ∝ b then a = kb

C = kN

380 calories = k × 20 ounces

k = 380 calories / 20 ounces

k = 19 calories/ounces

Now,we find C when N is 36 ounces.

C = kN

C = 19 calories/ounces × 36 ounces

C = 684 calories

Given that C varies directly as N, the value of Calories C when the number of ounces N is increased to the given value is 684 calories.

Step-by-step explanation:

The hypotenuse of a right triangle can be found from the other two sides by making use of the Pythagorean theorem. It tells you the square of the hypotenuse is the sum of the squares of the other two sides:

  c² = 4² +5²

  c² = 16 +25 = 41

  c = √41 ≈ 6.4

Answer:

Triangular prism

Step-by-step explanation:

Got it right on edge 2022 :)

The three-dimensional figure that has exactly three rectangular faces is a rectangular pyramid

The volume of a pyramid, is the product of the area of its base with the height of the pyramid, and divide by 3. We express this product with the formula V = ( 1/3) ×B×h, where B is the area of the base of the pyramid, and h is its height.

Volume of Pyramid = ( 1/3 )a²H

Given data ,

Let the pyramid be represented as A

Now , A rectangular prism has 6 faces, where each face is a rectangle.

A rectangular pyramid has 5 faces, where 4 faces are triangles and 1 face is a rectangle.

A triangular prism has 5 faces, where 2 faces are triangles and 3 faces are rectangles.

A triangular pyramid has 4 faces, where 3 faces are triangles and 1 face is a rectangle.

Hence , the only figure that has exactly three rectangular faces is a rectangular pyramid

The net income of Dorothy when she works 40 hours per week and her net pay is $2,718 monthly (4 week) is $17/ hour approximately.

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.

Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.

Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.

Thus,  [tex]a \div b = a[/tex] divided in b equal parts.

Also, we can write: [tex]a \div b = a \times \dfrac{1}{b}[/tex]

(it is since a = a times 1 so [tex]a/b = 1 \times (a/b) = (1/b) \times a[/tex])

For this case, we're given that:

Since there are 4 weeks in a month, and each week, Dorothy works 40 hours per week, so the number of hours she worked in those 4 weeks (one month work approx) is:

[tex]40+40+40+40 = 4 \times 40 = 160 \: \rm hours[/tex]

That means, Dorothy gets $2718.26 for 160 hours of work.

Thus, if we divide this salary in 160 parts equally, we'll get net hourly income of Dorothy, as shown below:

[tex]\text{1 hour's pay} = \dfrac{2718.26}{160}\approx 16.98 \approx 17 \: \rm dollars[/tex]

Thus, the net income of Dorothy when she works 40 hours per week and her net pay is $2,718 monthly (4 week) is $17/ hour approximately.

In response to the supplied query, we may state that Therefore, the Pythagorean theorem length of the hypotenuse is 30 units.

The Pythagorean Theorem, often known as the Pythagorean Theorem, is the fundamental Euclidean geometry relationship between the three sides of a right triangle. The area of a square with the hypotenuse side equals the sum of the areas of squares with the other two sides, according to this rule. The Pythagorean Theorem says that the square that spans a right triangle's hypotenuse opposite the right angle equals the sum of the squares that span its sides. It is sometimes written as the general algebraic notation a2 + b2 = c2.  

The Pythagorean theorem, which states that in a right triangle, the sum of the squares of the two legs (the sides that create the right angle) is equal to the square of the length of the hypotenuse, may be used to determine the length of the hypotenuse (the side opposite the right angle).

In this instance, we have two legs, one measuring 18 units and the other 24 units. Let's call the hypotenuse's length "c" for short. The Pythagorean theorem may then be used to determine the value of "c":

[tex]c^2 = 18^2 + 24^2\\c^2 = 324 + 576\\c^2 = 900\\c = \sqrt(900)\\c = 30[/tex]

Therefore, the length of the hypotenuse is 30 units.
