Answer:

B. 300

Step-by-step explanation:

Final figure volume = big cuboid volume - small cuboid volume

Volume of a cuboid = height x width x length

Final figure = (6 x 6 x 15) - (4 x 4 x 15)

Final figure = 540 - 240

Final figure = 300mm^2

To calculate the volume of a solid rectangular prism with a hole, subtract the volume of the hole from the volume of the prism. Without specific dimensions, we cannot determine the exact volume from the given options.

To find the volume of a three-dimensional figure that is a solid rectangular prism with a hole through the center, we need to subtract the volume of the hole from the volume of the solid rectangular prism. If the dimensions are not given in the question, we can look at examples provided in similar problems.

For instance, in problem 13, the volume of a rectangular solid with a square face of 5 cm and a length of 10 cm is found by multiplying its dimensions: Volume = length × width × height = 5 cm × 5 cm × 10 cm = 250 cm³. Similarly, we would calculate the volume of the outer prism and the inner prism in the given problem and subtract the inner volume from the outer to find the final volume.

The options provided (A. 60, B. 300, C. 540, D. 780) suggest specific volumes. Given the lack of specific dimensions in the question, it is not possible to determine the correct answer from the options provided without additional information.

Answer:

The Pie Eating Contest would be more skewed.

Step-by-step explanation:

In order to answer this, first we need to draw original histograms for both of these two events. Since all of the 20 people from the retirement community is attending one of the events, but we don't know which one, we need to draw new histograms for each of the events (see the attachment).

The only distinction of new histograms is the change in the fourth bin representing the 60-79 age group, since all visitors from retirement community fall into this age group.

A histogram is symmetrical if, when split in half by a vertical line, its left and right half act approximately as an object and its reflection in the mirror.

A histogram is skewed if, when split in half by a vertical line, one of its halves shows much greater values then the other.

So looking at our histograms, if all 20 people went to a Pie Eating Contest, that histogram would become more skewed and if all 20 people went to a Chili Cookoff, that histogram would become more symmetrical, which makes b) the correct answer.

Based on the information given, the correct option is B. The Pie Eating Contest would be more skewed.

This implies that when split in half by a vertical line, one of its halves will have greater values than the other.

Heat-induced decomposition is an illustration of chemical property.

Trying to break down is the phenomenon of decomposing. Whenever a substance is heated, it undergoes thermal breakdown, which is a chemical process.

At high temperatures, thermal breakdown processes occur. Before collapsing into the products, the reactions absorb a lot of energy.

Decomposition caused by heat is an example of a chemical property because it involves a substance changing into different substances through a chemical reaction.

The question asks which of the following options is an example of a chemical property. Chemical properties are characteristics of a substance that indicate its ability to undergo a chemical change, resulting in the formation of new substances. Options like boiling point, melting point, and electric conductivity are considered physical properties because they describe aspects of a substance that can be observed or measured without changing the substance's chemical identity. In contrast, an option like decomposition caused by heat is a chemical property because it involves a chemical change where the original substance is transformed into different substances as a result of the chemical reaction induced by heat.

Therefore, the correct answer to the original question, "which of the following is an example of a chemical property?" is:

Similarly, from the reference exercises provided, flammability is also a chemical property. It specifies a substance's ability to burn or ignite, causing it to change chemically and form new substances as it reacts with oxygen in the air.

Final answer:

To find how much milk Juan should use for 1 pound of flour, convert the flour to grams (454 g), set up a proportion based on the recipe's ratio, solve for the milk in milliliters, and then convert to cups. Juan will need approximately 1.135 cups of milk, or roughly 1 and 1/8 cups.

Explanation:

The question involves calculating how much milk Juan should use in his recipe based on the amount of flour he has. Since the recipe calls for 120 mL of milk for each 200 g of flour, we need to find out the equivalent amount for 1 pound of flour.

First, let's convert 1 pound of flour to grams, knowing that 1 pound is equivalent to approximately 454 grams. The recipe ratio is 120 mL to 200 g of flour, so we set up a proportion:

200 g flour : 120 mL milk = 454 g flour : x mL milk

To solve for x, we use cross multiplication:

(200 g) * (x mL) = (120 mL) * (454 g)

x = (120 mL * 454 g) / (200 g)

x ≈ 272.4 mL

Since there are about 240 mL in 1 cup of milk, we can convert the milliliters to cups:

x ≈ 272.4 mL / 240 mL/cup

x ≈ 1.135 cups of milk

Therefore, Juan should use approximately 1.135 cups of milk for 1 pound of flour. For ease of measuring, Juan can round this to about 1 and 1/8 cups of milk.

Step-by-step explanation:

Samuel can expect to draw a red card approximately 50 times.

To find out how many times Samuel can expect to draw a red card, we need to calculate the probability of drawing a red card and then multiply it by the number of times he selects a card.

Given:

- Number of red cards = 5

- Number of blue cards = 20

- Number of green cards = 25

- Total number of cards = 5 (red) + 20 (blue) + 25 (green) = 50

The probability of drawing a red card is the ratio of the number of red cards to the total number of cards:

[tex]\[ P(\text{Red}) = \frac{\text{Number of red cards}}{\text{Total number of cards}} = \frac{5}{50} = \frac{1}{10} \][/tex]

Now, to find the expected number of times Samuel will draw a red card, we multiply the probability of drawing a red card by the total number of times he selects a card:

[tex]\[ \text{Expected number of red cards} = P(\text{Red}) \times \text{Total number of selections} \][/tex]

Substituting the values:

[tex]\[ \text{Expected number of red cards} = \frac{1}{10} \times 500 = 50 \][/tex]

So, Samuel can expect to draw a red card approximately 50 times.

[tex]f^{-1}(x) = \frac{1}{12}(x+20)[/tex]

Step-by-step explanation:

Given: f(x) = 4(3x - 5)

Is required to find f⁻¹(x)

f(x) = y = 4(3x - 5)

∴ y = 4 * 3x - 4 * 5

∴ y = 12x - 20 ⇒ add 20 to both sides

∴ y + 20 = 12x ⇒ divide both sides by 12

∴ [tex]\frac{1}{12} (y+20) = x[/tex]

Replace the places of x and y.

∴ [tex]y=\frac{1}{12} (x+20)[/tex]

∴ [tex]f^{-1}(x) = \frac{1}{12}(x+20)[/tex]

Answer:

57.97 cm²

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = [tex]\frac{1}{2}[/tex] h( a + b)

where h is the perpendicular height between the parallel bases and a, b are the bases.

Here h = 6.2, a = 7.9 and b = 10.8, thus

A = 0.5 × 6.2 (7.9 + 10.8)

   = 3.1 × 18.7 = 57.97 cm²

Answer:

Step-by-step explanation:

Area of trapezium = 1/2(a + b)h

a = 7.9cm, b = 10.8cm and h = 6.2cm

Area = 1/2(7.9 + 10.8)×6.2

Area = 1/2 × 18.7 × 6.2

Area = 57.97cm²

Therefore the correct option is sin(5x).

Step-by-step explanation:

i) The hammer thrower rotates exactly 5 times in 2[tex]\pi[/tex] seconds.

  Therefore one rotation is completed in [tex]\frac{2\pi }{5}[/tex] seconds.

ii) Since the motion of the hammer is represented by a sine function therefore

  one rotation is considered to be one full cycle and the time period of that cycle

  is given in equation i) and it is T = [tex]\frac{2\pi }{5}[/tex]  seconds.

iii) the equation of a sine function is given by sin(2[tex]\pi[/tex][tex]\frac{1}{T}[/tex]) which in this case would

   be sin(2[tex]\pi[/tex] × [tex]\frac{1}{\frac{2\pi }{5}}[/tex] × x) = sin(5x)

Therefore,

[tex]PR=10\ unit[/tex]

Step-by-step explanation:

Given:

PR = 2x

RQ = 25

Say M divide PQ such that

PM = 6

MQ = 3x

∠PRM ≅ ∠QRM

RM is the angle Bisector of angle PRQ

To Find:

PR = ?

Solution:

Angle Bisector Theorem:

The angle bisector theorem is concerned with the relative lengths of the two segments that a triangle's side is divided into by a line that bisects the opposite angle.

It equates their relative lengths to the relative lengths of the other two sides of the triangle.

Here RM is the angle Bisector of angle PRQ

Therefore,

[tex]\dfrac{PR}{RQ}=\dfrac{PM}{MQ}[/tex] ...Angle Bisector Theorem.

Substituting the values we get

[tex]\dfrac{2x}{25}=\dfrac{6}{3x}\\\\x^{2}=25\\Square\ Rooting\\x=\pm\sqrt{25}\\x=5[/tex]

As x cannot be negative x =5

Substituting x value in PR we get

[tex]PR=2\times 5=10\ unit[/tex]

Therefore,

[tex]PR=10\ unit[/tex]

Step-by-step explanation:

We have,

[tex]4\dfrac{6}{7}+7\dfrac{3}{14}[/tex]

To find, the common denominator of [tex]4\dfrac{6}{7}+7\dfrac{3}{14}[/tex] = ?

∴ [tex]4\dfrac{6}{7}+7\dfrac{3}{14}[/tex]

= [tex]\dfrac{4\times 7 +6}{7} +\dfrac{7\times 14 +3}{7}[/tex]

[tex]=\dfrac{34}{7} +\dfrac{101}{7}[/tex]

Taking the common as [tex]\dfrac{1}{7}[/tex], we get

=[tex]\dfrac{1}{7}[/tex][tex](34+101)[/tex]

The denominator = 7

∴  The common denominator of [tex]4\dfrac{6}{7}+7\dfrac{3}{14}[/tex] = 7

Hence, the common denominator of [tex]4\dfrac{6}{7}+7\dfrac{3}{14}[/tex] = 7
