Several cheeses are for sale. The cheese comes in wedges shaped like sectors of a circle. All of the wedges are the same height. Tyler bought a wedge. He measured the arc length of the wedge to be 12 cm and the radius to be 8 cm. Priya bought a wedge that came from a circular cheese block with radius 9 cm. The block was cut into 6 congruent sectors. Whose wedge is larger? Explain or show your reasoning.

Answers

Tyler's wedge is larger

The arc length of Priya's wedge is only 9.42, and Tyler's is 12

Tayler's wedge is larger.

What is arc length?

"Arc length is the distance along the part of the circumference of any circle."

Formula to calculate the circumference of a circle:

S = 2 × π × r

where, r is the radius of the radius of a circle

In this question,

Tyler bought a wedge shaped cheese with arc length 12 cm and radius 8 cm.

Priya bought a wedge that came from a circular cheese block with radius 9 cm and the block was cut into 6 congruent sectors.

The circumference of circular cheese block with radius 9 cm would be,

⇒ s = 2 × π × 9

⇒ s = 18π cm

Since, the block was cut into 6 congruent sectors.

The arc length of each block would be, 18π / 6 = 3π cm

That is, 9.43 cm

Since 12 > 9.43, Tayler's wedge is larger.

The top, front, and side views of a rectangular prism are shown.

(1) side view
How many unit cubes are used to build the solid?
unit cubes are used to build the solid.​

Answers

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.

A rope is stretched from the top of a
7-foot tent pole to a point on the ground
12 ft from the base of the pole. How long
is the rope ?

Answers

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:

Definition Of Pythagoras Theorem :

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.

Given:

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

[tex]\begin{aligned}&C^{2}=A^{2}+B^{2} \\&C^{2}=7^{2}+12^{2} \\&C^{2}=49+144 \\&C^{2}=193 \\&C=\sqrt{193} \\&C=13.89 \text { feet }\end{aligned}[/tex]

Hence, the length of the rope is 13.89ft.

A certain television is advertised as a 54-inch TV (the diagonal length). If the width of the TV is 40 inches, how tall is the TV? Round to the nearest tenth of an inch.

Answers

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:

  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.

A man is five times as old as his son. Four years ago the man was thirteen times as old as his son.
Find their present ages.

Answers

Answer:

Age of son = 6 years

Age of man = 5×6 = 30 years

Step-by-step explanation:

GIVEN :-

A man is 5 times as old as his son. (In Present)4 years ago , the man was 13 times as old as his son

TO FIND :-

The present ages of the man & his son.

SOLUTION :-

Let the present age of son be 'x'.

⇒ Present age of man = 5x

4 years ago ,

Age of son = (Present age of son) - 4 = x - 4

Age of man = (Present age of man) - 4 = 5x - 4

The man was thirteen times as old as his son. So,

[tex]=> 5x - 4 = 13(x - 4)[/tex]

Now , solve the equation.

Open the brackets in R.H.S.

[tex]=> 5x - 4 = 13x - 52[/tex]

Take 5x to R.H.S. and -52 to L.H.S. Also , take care of their signs because they are getting displaced from L.H.S. to R.H.S. or vice-versa.

[tex]=> 13x - 5x = 52 - 4[/tex]

[tex]=> 8x = 48[/tex]

Divide both the sides by 8

[tex]=> \frac{8x}{8} = \frac{48}{8}[/tex]

[tex]=> x = 6[/tex]

CONCLUSION :-

Age of son = 6 years

Age of man = 5×6 = 30 years
