Find the numbers if-
A) 0.6of it is 30
B)1.5 of it is30
C)1.6 of it is 32

Answers

Answer:

A) 50

B) 20

C) 20

Step-by-step explanation:

To solve the first question, we can multiply both sides by 10.

Thus, we get:

6x = 300.

Then, divide by 6, to get x:

x = 50.

You can do the same thing to all of these questions.

I've already checked the answers, but if you don't trust them, just pluck the values in.

For example, let's check the answer for question A.

0.6*50 is supposed to equal 30.

Does it equal? Yes, so we know that the answer is correct.

A business developer would like to purchase an abandoned corner lot in a small town and build a small convenience store with gasoline pumps on the site. Town leaders are concerned about potential traffic and noise impact to the adjacent neighborhood and send printed surveys to 500 homes in the affected area. Of the 123 surveys returned, 87% oppose the plan to develop the corner lot. How could the sampling design cause town leaders to overestimate or underestimate overall support of the development plan?
(A) The leaders may underestimate support because only 123 surveys were returned.
(B)The leaders may overestimate overall support because many residents who did not receive surveys will support the plan.
(C)The leaders may underestimate overall support because many residents who support the plan may be less likely to respond.
(D)The leaders may underestimate support because it can be assumed that all residents who did not return the surveys would support the plan.

William has ten colored game pieces in a box: 3 yellow pieces, 5 orange pieces, 1 green piece, and 1 red piece. What is the probability that if he randomly pulls a game piece out of the box it will be orange? Enter your answer as a decimal.

Answers

Answer:

Step-by-step explanation:

yellow= .30

orange= .50

green= .10

red- .10

The required probability of randomly selecting an orange piece is 0.5.

What is probability?

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

William has ten colored game pieces in a box: 3 yellow pieces, 5 orange pieces, 1 green piece, and 1 red piece.

There are a total of 10 game pieces in the box.

Out of those, 5 are orange.

This means the number of favorable outcomes = 5 and the total number of outcomes = 10.

So, the required probability is :

5/10, or 0.5 (5 divided by 10, expressed as a decimal).

Therefore, the probability of randomly selecting an orange piece is 0.5.

A triangular prism and two nets are shown:

A right triangular prism is shown with two nets. The triangular base of the prism has height 5 inches, base 12 inches, and hypotenuse 13 inches. The length of the prism is 15 inches. Net A has 3 rectangles having dimensions 5 by 15, 15 by 12, and 15 by 13, and two triangles having legs 5 inches and 12 inches. Net B has 3 rectangles having dimensions 5 by 13, 13 by 12, and 13 by 15, and two triangles having legs 5 inches and 12 inches.

Which is the correct net of the prism and what is the surface area of the prism?

Net B with 420 square inches
Net B with 500 square inches
Net A with 510 square inches
Net A with 450 square inches

Answers

Answer:

Net for the prism will have 3 rectangles with dimensions 5 by 15, 12 by 15 , and 13 by 15, and 2 triangles with legs 5 inches and 12 inches.

The correct net is net a.

Surface area = sum of areas of the three rectangles and sum of the two triangles.

SA = (5 x 15) + (12 x 15) + (13 x 15) + (5 x 12) = 75 + 180 + 195 + 60 = 510 square inches.

a rectangular box has length 20 cm width 6 cm and height 4 cm find how many cubes of side 2 cm that will fit into the box

Answers

Answer:

Step-by-step explanation:

Get the volume of the rectangular box

Volume of the rectangular box = length * width * height

Volume of the rectangular box = 20 * 6 * 4

Volume of the rectangular box = 480cm³

Get the volume of the cube;

Volume of the cube = l³

Volume of the cube = 2³

Volume of the cube = 8cm³

Amount of 2cm³ cube that will fit = volume of the box/volume of the cube

Amount of 2cm³ cube that will fit = 480/8

Amount of 2cm³ cube that will fit = 60

Hence 60 2cm³ cube will fit into the box

Step-by-step explanation:

Jon is drawing a quadrilateral.

The length of each side is 5.2cm to 1 decimal place.

Complete the error interval for the length of one side.

And Complete the error interval for the perimeter.

Please help with this one urgently.

Answers

Answer:

We know that the measure of each side is:

5.2cm to 1 decimal place.

Then we can assume that the error is 0.05cm (half of the second decimal place).

With this, the interval of the length of each side will be:

(5.2cm - 0.05cm) = 5.15cm (as the minimum)

(5.2cm + 0.05cm) = 5.25cm (as the maximum)

Then the interval is (5.15cm, 5.25cm)

2) We know that the perimeter of a square of sidelength L is:

P = 4*L

In this case, the minimum perimeter will be if we choose the smallest sidelength, this is:

P = 4*5.15cm = 20.6cm

And the maximum perimeter can be:

P = 4*5.25cm = 21cm

Then the interval is: (20.6cm, 21cm)

Here we can see that the error for the perimeter is 0.2cm, which is equal to 4 times the error of the length of a side (0.05cm) , as expected.
