Answer:

The Cholula Pyramid has a bigger volume out of the two.

Step-by-step explanation:

The volume of a Pyramid is V=1/3Bh

Volume of the Choulula = 1/3 (2,178,576)(217)= 157,583,664

Volume of The Cheops Pyramid = 1/3 (570,025)(480)=91,204,000

157,583,664 is greater than 91,204,000

To determine the pyramid with the most volume using the formula for the volume of a pyramid.

The volume of a pyramid: To determine which pyramid has the most volume, we use the formula for the volume of a pyramid: Volume = (1/3) × base area × height.

Cholula Pyramid: Volume = (1/3) × 1456 ×  121 = 7307680 cubic feet

Cheops Pyramid: Volume = (1/3) × [tex](585)^2[/tex] × 464 = 47640550 cubic feet

Therefore, the Cheops Pyramid has the most volume.

Answer:

111 pounds

Step-by-step explanation:

A boy holding a stack of 9 identical books steps on a scale and weighs 138 pounds.

If the boy's weight is represented as B and the books are represented as b, this implies that:

B + 9b = 138

The boy then holding a stack of 3 of the same books again steps on the scale and weighs 120 pounds. This implies that:

B + 3b = 120

This has yielded two simultaneous equations:

B + 9b = 138

B + 3b = 120

We can solve by subtracting the second from the first.

B + 9b = 138

- (B + 3b = 120)

-----------------------

=> 6b = 18

b = 18 / 6 = 3 pounds

This means that each book weighs 3 pounds.

Putting b back in the second equation:

B + (3 * 3) = 120

B + 9 = 120

B = 120 - 9

B = 111 pounds

Therefore, the boy weighs 111 pounds.

Answer:

The boy would weigh 111 lbs.

Answer:

155.9 = h

Step-by-step explanation:

Since it is an equilateral triangle, the angles are all 60 degrees

Call the angle on the bottom right theta

Theta = 60 degrees

The angle h makes with the base is 90 degrees so it is a right triangle

sin theta = opp/ hyp

sin 60 = h/ 180

Multiply each side by 180

180 sin 60 = h

155.8845727  = h

To the nearest tenth

155.9 = h

Answer:

r / n

62.2%

33.3%

Step-by-step explanation:

The formula to be used is to divide the number of times that it came out by the total number of times the event was repeated because this was the experiment that was carried out, therefore this would be the experimental formula:

r / n

r = specific event (that the 10 dollar bill comes out)

n = total events

To calculate, we know the previous values r = 28 and n = 45, we replace:

28/45 = 0.622

that is, 62.2% is the experimental probability.

To calculate the theoretical propagation, we know that there are 3 types of banknotes and we want 1 of those 3 types to appear, therefore:

1/3 = 0.333

Ie 33.3% is the theoretical probability

We have been given that a baseball coach graphs some data and finds the line of best fit. The equation for the line of best fit is [tex]y=0.32x-20.51[/tex],where x is the number of times at bat and y is the number of hits.

To find the number of hits in 175 times at bats, we will substitute [tex]x=175[/tex] in our given equation as:

[tex]y=0.32(175)-20.51[/tex]

[tex]y=56-20.51[/tex]

[tex]y=35.49[/tex]

Upon rounding to nearest whole number, we will get:

[tex]y\approx 35[/tex]

Therefore, the coach would expect 35 hits from a player who is at bat 175 times.

The expected number of hits  = 35.

The given line of best fit is [tex]y=0.32x-20.51.[/tex]

Given that:

x = the number of times a bat = 175.

We have to find y = ?

We plug x = 175 in the given equation.

[tex]y=0.32x-20.51\\y=0.32(175)-20.51\\y=35.49[/tex]

The integer before 35.49 is 35. [Because, number of hits can not be fraction.]

So the expected number of hits  = 35.

Answer:

31.2

Step-by-step explanation:

To work out 60% of 52 you would first need to find 10%. You can do this by dividing 52 by 10, this gives you 5.2.

The final step is to multiply 5.2 by 6, this gives 31.2. This is because in order work out 60% you multiply 10% by 6.

1) Divide 52 by 10.

[tex]52/10=5.2[/tex]

2) Multiply 5.2 by 6.

[tex]5.2*6=31.2[/tex]

Answer:

2 is the constant of proportionality

Step-by-step explanation:

we look at the linear function y = 2x + 2

You ask for the constant of proportionality.

y  related to x

y =  2 * (x + 1)

y/(x + 1) = 2  

2 is the constant of proportionality

Answer:

Step-by-step explanation:

Given that, a series of triangle,

For the sine and cosine to be equal, then,

Sinθ = Cosθ

From, trigonometry identities

Sinθ = Cos(90-θ)

Then,

θ = 90-θ

θ + θ = 90

2θ = 90

θ = 90 / 2

θ = 45°

From the triangle given, using trigonometry ratio,

Sinθ = opposite / hypotenuse.

Sinθ = 20 / 25

Sinθ = 0.8

θ = arcsin(0.8)

θ = 53.13°

The other angles at the triangle is

90-53.13 = 36.87°.

Answer:

The length of the fence is 38 yards

These are the expressions

1. Perimeter = 2l+ 2w

2. Perimeter = 2(l+w)

Step-by-step explanation:

This problem bothers on the mensuration of flat shapes, a rectangle.

The length of the fence is the perimeter of the garden which is the expression that Chole could use

1. Perimeter = 2l+ 2w

2. Perimeter = 2(l+w)

Given data

Length = 11 yards

Width = 8 yards

Perimeter = 2(11)+ 2(8)

Perimeter = 22+16

Perimeter = 38 yards

Gavin should mix equal amounts of the primary colors red and yellow to achieve the greatest possible amount of orange paint through subtractive color mixing.

Gavin is looking to mix paint to create the greatest possible amount of a new paint color. To do this, he should use the primary colors red and yellow to make the secondary color orange. When mixing paints, which is a form of subtractive color mixing, combining these two pigments will result in a new hue without diminishing the amount of paint he has.

In subtractive color mixing, the secondary color orange is created by mixing the primary colors red and yellow in equal proportions. To obtain the largest amount of new paint, Gavin should mix equal parts of the red and yellow shades, assuming that the volumes of paints being mixed are also equal. Thereby, making use of the entire quantity of red and yellow paint to create the largest possible amount of orange paint.

It's important to note that this approach is different from additive color mixing, which involves light colors and operates under a different set of rules. In Gavin's scenario with pigments, red and yellow are the primary colors he should focus on to achieve the desired outcome.

Answer: 210

Explanation: To find the least common multiple for the integers 30 and 35, we start by making a factor tree for each of our integers.

So 30 is 10 · 3 and 10 is 5 · 2.

35 is 7 · 5.

Notice that our 5's match up as factors of each of our integers.

When finding the least common multiple, we simply multiply all of our factors together but since the 5's match up,

we only multiply by a 5 once.

So our least common multiple or LCM is

5 · the 2 that doesn't match up · the 3 that

doesn't match up · the 7 that doesn't match up.

So we have 5 · 2 · 3 · 7 or 210.
