Answer:

The correct answer is A) undefined.

Step-by-step explanation:

In order to find this, pick two points on the line and use the slope equation. For the purpose of this, we'll use points (3, 1) and (3, 2).

m(slope) = (y2 - y1)/(x2 - x1)

m = (2 - 1)/(3 - 3)

m = 1/0

Since we cannot divide by 0, we know that it is undefined.

The balanced scale represents the equation: 3x + 1 = x + 3

Afina-wow [57]

<u>Given</u>:

The given balanced scale is represented by the equation

$3x+1=x+3$ ----- (1)

We need to determine the process that balance the scale.

<u>Process to balance the scale:</u>

Given that the if one x block is subtracted from the right side and three numbered blocks are subtracted from the left side.

Thus, the equation (1) becomes

$(3x+1)-3=(x+3)-x$

$3x-2=3$ ----- (2)

Now, to balance the scale, let us subtract one block x from the left side and subtract three numbered blocks from the right side.

Thus, the equation (2) becomes,

$(3x-2)-x=3-3$

$2x-2=0$ ------ (3)

Thus, the equation (3) is the same as the equation (1).

Hence, the process required to balance the scale is to subtract one x block from the left side and subtract three numbered blocks from the right side.

Therefore, Option B is the correct answer.

Hannah is designing containers to hold 300 cm3 of juice. Which container is more efficient?

Lubov Fominskaja [6]

Answer:

a) 2nd container is more efficient and contains the elements for a container.

b) The cylinder has a........A)Smaller surface area B)bigger C)equal

And will cost.....A)Less to produce B)more C)The same

Step-by-step explanation:

a) The 2nd container has these elements:

Width 20.5cm

Length 6.5cm

side 3.25cm

So, the volume in cubic cm is 20.5 x 6.5 x 3.25 = 433cm3.

This container can hold the 300cm3 of juice.

b) A cylinder is a geometric solid common in everyday life. Examples of a cylinder are soup cans, food tins, drink cans, candles, toilet paper rolls, cups, aerosol cans, flower vases, test tubes, fire extinguishers, plant containers, salt shakers and pencil holders. The two ends are called bases, and are usually circular. Though, they can take other shapes. When a cylinder is unrolled and flattened out, the side is actually a rectangle.

The surface area of a cylinder is the surface area of each end plus the surface area of the side. The mathematical formula is 2π * r2, where π is the pie and r is the radius of the end and r2 is r squared..

Nadia’s bookshelf contains 10 fiction books, two reference books, and five nonfiction books. What is the probability that she ra

pshichka [43]

Answer:

5/136

Step-by-step explanation:

Probability is the chance of an event happening.

Probability = (Favorable outcome)/(total outcome)

P(r and n) = 2/17 × 5/16

=(2 × 5)/(17 × 16)

= 10/272

= 5/136

The radius of the circular lens of a magnifying glass is 4 centimeters.

Nadusha1986 [10]

Answer: 50.24 square centimeters.

Step-by-step explanation:

Given: The radius of the circular lens of a magnifying glass = 4 centimeters

The area of a circle is given by :-

$\text{Area}=\pi r^2$ , where r is the radius of the circle.

Then the area of the circular lens of a magnifying glass is given by :-

$\text{Area}=\pi (4)^2=(3.14)(16)=50.24\text{ square centimeters }$

Hence, the area of the circular lens of a magnifying glass = 50.24 square centimeters.
