A) 22.4
B) 43.7
C) 85.3
D) 4.75

Step-by-step explanation:

such a rectangular prism is in that sense like a cube (or die) : it has 6 sides or surface areas. top, down, front, back, left, right.

to get the total surface area we need to calculate each individual side area and sum all 6 of them up.

since it is a rectangular shape, there are 3 pairs of equal side areas, so, we really need to calculate only 3 different ones :

front and back : each is

10×9 = 90 in², both together are 180 in²

left and right : each is

8×9 = 72 in², both together are 144 in²

top and bottom : each is

10×8 = 80 in², both together are 160 in²

the total surface area of the prism is

180 + 144 + 160 = 484 in²

Answer:

10/15, or 2/3

Step-by-step explanation:

To get common denominator multiply 2/5 by three: 6/15

4/15 + 6/15 = 10/15

divide by 5: 2/3

Hey there!

4/15 + 2/5

≈ 4/15 + 6/15

≈ 4 + 6 / 15 - 0

≈ 10 / 15

≈ 10 ÷ 5 / 15 ÷ 5

≈ 2/3

Therefore, your answer is: 2/3

Good luck on your assignment & enjoy your day!

Answer:

4032

Step-by-step explanation:

1 day is 1440 min

1440 divided by 10 = 144

144 times 4 = 576

576 times 7 (because there are 7 days in a week) = 4032

Answer:

true, because in a point it is (x,y) which the x moves left and right and the y moves up and down and the y axis goes straight up and down in the middle of the graph so the x would reflect from -9 to 9 because it is going across the y axis going up and down.

Answer: The answer is −4x−9.8

Step-by-step explanation:

−7x−9−−4.2+3x−5

The opposite of −4.2 is 4.2.

−7x−9+4.2+3x−5

Add −9 and 4.2 to get −4.8.

−7x−4.8+3x−5

Combine −7x and 3x to get −4x.

−4x−4.8−5

Subtract 5 from −4.8 to get −9.8.

−4x−9.8

[tex]\sf x = 4\sqrt{2}[/tex]

Given:

using cosine rule:

[tex]\sf cos(x) = \dfrac{adjacent}{hypotenuse}[/tex]

[tex]\sf cos(45) = \dfrac{4}{x}[/tex]

[tex]\sf x = \dfrac{4}{cos(45)}[/tex]

[tex]\sf x = 4\sqrt{2}[/tex]

Solution:

Step-1: Find the missing angle.

Step-2: Review the following.

Step-3: Use Pythagoras theorem.

The element that has chemical properties most similar to element X is element 1.

Elements on the periodic table are ordered accordingly to the number of protons in each element.

The first one is hydrogen, with 1 proton, the second is helium, with two protons, and so on.

So, element 3 has one proton less than x, and element 4 has one proton more than x.

Then we have two more relations:

Horizontal lines are called periods, so 3, x, and 4 are on the same period (it is related to the energy level of the valence's electrons).

Vertical lines are called families because elements in vertical lines have similar chemical behavior.

This is the one that we care for this problem, we want to see which element has chemical properties most similar to element X, so we need to see which element is on the same family as element X.

As you can see, the only element on the same vertical line as X is element 1, so the correct option will be A.

I took the quiz

Answer:

168 km

Step-by-step explanation:

1 hour = 60 minutes

⇒ 5 hours = 5 × 60 = 300 minutes

We have been told the distance that the car traveled in 25 minutes.

Therefore, divide 300 minutes by 25 minutes:

[tex]\implies \sf \dfrac{300}{25}=12[/tex]

So there are 12 'lots' of 25 minutes in 5 hours.

Therefore, to find out how far the car travels in 5 hours, multiply the distance traveled in 14 km by 12:

⇒ total distance = 12 × 14 = 168 km

25min=25/60=5/12h

Speed:-

Total distance in 5h

The inference procedure that should be used is a hypothesis testing.

It should be noted that hypothesis testing simply means a statistical test when an individual tests and assumption regarding a population parameter.

In this case, since the data will be used to compare the percents of students from rural backgrounds among dropouts and graduates, the hypothesis testing is appropriate. This is important to assess the plausibility of the hypothesis.

Answer:

B

Step-by-step explanation:

that is the definition of a function : every valid value of x gets exactly one value of y assigned as function result value.

that allows gaps. not every value on the x-axis has to be a valid x value for the function. and neither do we need every possible y value to be a valid function result value.

so, if we consider x to be the set of {2, 4, 6, 9}, then this is indeed a function.

2 gets 3, 4 gets 9, 6 gets 10, and 9 gets 5 assigned as y (function result) value.

all good and perfect - exactly one assigned value for every valid x value.

according to question:

perimeter of square = 16 units

4a = 16

where a is the side length

a = 16/4

= 4 units

Step-by-step explanation:

that r = P/(2π) so A = π(P/(2π))2 = P2/(4π). Any positive area less than this is also possible. So in this problem the largest area possible is (16 in.)2/(4π) = 64/π sq.

Answer:

[tex]{x,y}={3,3}[/tex]

Step-by-step explanation:

System of Linear Equations entered :

[tex][1] 2x + 3y = 15\\ [2] x + y = 6[/tex]

Graphic Representation of the Equations :

3y + 2x = 15        y + x = 6  

Solve by Substitution :

// Solve equation [2] for the variable  y

 [2]    y = -x + 6

// Plug this in for variable  y  in equation [1]

  [1]    2x + 3•(-x +6) = 15

  [1]    -x = -3

// Solve equation [1] for the variable  x

  [1]    x = 3

// By now we know this much :

   x = 3

   y = -x+6

// Use the  x  value to solve for  y

   y = -(3)+6 = 3

Solution :

{x,y} = {3,3}
