Answer:

36.3

Step-by-step explanation:

I tried using the Pythagorean Theorem to measure the length (tallness) of the TV.

[tex]a^2 + b^2 = c^2[/tex]

[tex]a^2 + (40)^2 = (54)^2[/tex]

[tex]a^2 + 1600 = 2916[/tex]

[tex]a^2 = 2916-1600 = 1316[/tex]

[tex]a = \sqrt{1316}[/tex]

[tex]a = 36.27671429[/tex]

When this is rounded up to the nearest tenth, it would go up to 36.3.

So, the length (tallness) of the TV would be 36.3 inches.

Answer:

Step-by-step explanation:

we know two sides of a triangle, one side is 7 feet, the other is 12 feet , so use Pythagoras theorem

[tex]C^{2}[/tex] = [tex]A^{2}[/tex] + [tex]B^{2}[/tex]

[tex]C^{2}[/tex] = [tex]7^{2}[/tex] + [tex]12^{2}[/tex]

[tex]C^{2}[/tex] = 49 + 144

[tex]C^{2}[/tex] = 193

C = [tex]\sqrt{193}[/tex]

C = 13.89 feet

Answer:

The square of the hypotenuse equals the square of the sum of the other two sides.

13.89ft

Step-by-step explanation:

The Pythagorean theorem states that the total of the squares on a right triangle's legs equals the square on the hypotenuse (the side opposite the right angle)—or, in popular algebraic form, a2 + b2 = c2.

Height of the Tent Pole = 7ft.

Base of the Pole of the Tent = 12ft.

Now we will use Pythagoras theorem to find how long the rope is.

Use of Pythagoras theorem

Hence, the length of the rope is 13.89ft.

Using linear functions, it is found that:

a)

[tex]y_A(x) = 8 + x[/tex]

[tex]y_B(x) = 4 + 2x[/tex]

b) They will have the same height after 4 weeks.

A linear function has the following format:

[tex]y = mx + b[/tex]

In which:

Item a:

Plant A has a height of 8 centimeters and grows 1 centimeter each week, hence:

[tex]y_A(x) = 8 + x[/tex]

Plant B has  a height of 4 centimeters and grows 2 centimeters each week, hence:

[tex]y_B(x) = 4 + 2x[/tex]

The system is:

[tex]y_A(x) = 8 + x[/tex]

[tex]y_B(x) = 4 + 2x[/tex]

Item b:

Equaling the equations:

[tex]y_A(x) = y_B(x)[/tex]

[tex]8 + x = 4 + 2x[/tex]

[tex]x = 4[/tex]

They will have the same height after 4 weeks.

Answer:

  A

Step-by-step explanation:

If the price of a hot dog is x, then the price of two hot dogs is 2x, and the price of 3 of them is 3x.

If the price of a drink is y, then the price of 2 drinks is 2y.

So, we have the price of 2 hotdogs and 2 drinks is 4.75.

  2x + 2y = 4.75

And the price of 3 hot dogs and 1 drink is 7.75.

  3x + y = 7.75

This pair of equations matches those in choice A.

_____

Comment on the question

We know right away that something is screwy here, because the cost of two hotdogs and 2 drinks should be an even number. 4.75 is not an even number. If we solve this set of equations, we find the cost of a drink is negative—not something you're likely to see in the real world.

So, this is an exercise in writing equations. It has nothing to do with finding real prices.

Answer:

Step-by-step explanation:

new side lengths = original length / scale factor

Answer:

Use multiplication and dividing.

Step-by-step explanation:

If you want to convert to a smaller unit, you must multiply.

For example...

4 Feet to Inches:

[tex]4 * 12 =48[/tex] inches

2 Yards to Inches:

[tex]2 * 3 = 6[/tex] feet

[tex]6 * 12 = 72[/tex] inches

If you want to convert to a larger unit, you must divide.

336 Inches to Feet:

[tex]336/12=28[/tex] feet

756 Inches to Yards:

[tex]756/12=63[/tex] feet

[tex]63/3=21[/tex] yards

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the views are not shown.

So, I will answer this question with the attached views of a rectangular prism.

Required

The number of cubes used

For the attached views of the rectangular prism, we will make use of the following representations

Top view [tex]\to[/tex] Width

Front view [tex]\to[/tex] Height

Side view [tex]\to[/tex] Length

So, we have:

[tex]Width = 2 units[/tex]

[tex]Height = 6 units[/tex]

[tex]Length = 1\ unit[/tex]

The number of cubes is calculated by solving for the volume of the prism.

For a rectangular prism, the volume is:

[tex]Volume = Length * Width * Height[/tex]

[tex]Volume = 2 * 6 * 1[/tex]

[tex]Volume = 12[/tex]

This implies that 12 cubes were used to build the solid.

Answer:

13.7

Step-by-step explanation:

It forms a triangle.

They are trying to find the height, cause they say the east-bound car went east so that makes the bottom of the triangle, the width. They also give is the distance in between both cars so that's the hypotenuse so let's set up the equation...

15² - 6² = 189

now we square root it

√189 = 13.7

Answer:

Step-by-step explanation:

The volume of a rectangular prism is shown below:

We are given the an area of  

173.6

cm

and a height of  

9

cm

.

We also know that the formula for area is  

l

w

, meaning we can substitute the area for  

l

w

in the volume formula.

Now let's plug in what we know into the formula and solve for the volume:

V
