Step-by-step explanation:

Given:

Given that the height of the pyramid is 12 units.

The base of the triangle is 8 units.

The height of the triangle is 6 units.

We need to determine the volume of the pyramid.

Area of the triangle:

The area of the triangle can be determined using the formula,

[tex]A=\frac{1}{2} bh[/tex]

where b is the base of the triangle and h is the height of the triangle.

Substituting the values, we get;

[tex]A=\frac{1}{2}(8)(6)[/tex]

[tex]A=\frac{1}{2}(48)[/tex]

[tex]A=24[/tex]

Thus, the area of the triangle is 24 square units.

Volume of the pyramid:

The volume of the pyramid can be determined using the formula,

[tex]V=\frac{1}{3}AH[/tex]

where A is the area of the triangle and H is the height of the pyramid.

Substituting the values, we get;

[tex]V=\frac{1}{3}(24)(12)[/tex]

[tex]V=\frac{1}{3}(288)[/tex]

[tex]V=96[/tex]

Thus, the volume of the pyramid is 96 cubic units.

In a right triangle with one leg of length 3, the other leg of length 4, and the hypotenuse of length x, the Pythagorean theorem formula (3² + 4² = x²) gives the length of x as √25, or 5 units.

In Mathematics, a right triangle has one angle that is a right angle (90 degrees). In these triangles, the Pythagorean theorem applies, which says that the square of the length of the longest side (hypotenuse) is equal to the sum of squares of the other two sides (legs).

If x is a leg of the triangle, then its length can be found by rearranging the Pythagorean theorem formula. If the length of one leg is 3, the other is 4, and the length of the hypotenuse is x, then the equation is: 3² + 4² = x².

That simplifies to 9 + 16 = x², and further to x² = 25. Taking the square root of both sides gives us the length of x as 5 units.

Given:

The circumference of the smaller is 30% of the circumference of the larger circle.

We need to determine the circumference of the larger circle.

Diameter of the larger circle:

The diameter of the smaller circle is 9 in.

Since, the circumference of the smaller is 30% of the circumference of the larger circle, we have;

[tex]S=0.3L[/tex]

where S is the circumference of the smaller circle and L is the circumference of the larger circule.

[tex]\pi(9)=(0.3)\pi d[/tex]

    [tex]9=0.3d[/tex]

  [tex]30=d[/tex]

Thus, the diameter of the larger circle is 30 inches.

Circumference of the larger circle:

The circumference of the larger circle is given by

[tex]C=\pi d[/tex]

[tex]C=3.14\times 30[/tex]

[tex]C=94.2[/tex]

Thus, the circumference of the larger circle is 94.2 inches.

Answer:

the answer is 75.36cm but it can rounded off to 75.4cm

Step-by-step explanation:

The solution to the equation 3y + 6 + 4y - 7 = -8 is y = -1.

We have,

To solve the equation 3y + 6 + 4y - 7 = -8 for y, we can combine like terms and isolate the variable.

Combining like terms on the left side of the equation, we have:

3y + 4y + 6 - 7 = -8

Simplifying further:

7y - 1 = -8

Next, let's isolate the y-term by moving the constant term to the other side of the equation:

7y = -8 + 1

Simplifying:

7y = -7

Finally, divide both sides of the equation by 7 to solve for y:

y = -7/7

Simplifying the fraction:

y = -1

Therefore,

The solution to the equation 3y + 6 + 4y - 7 = -8 is y = -1.

The number 125 in the equation B = 12.5(125 - n) represents the point at which the electric bill would be $0 if the museum uses 125 solar panels. It means the bill decreases by $12.5 for the installation of each additional solar panel.

The best interpretation of the number 125 in the equation B = 12.5(125 - n) is that the monthly electricity bill for a museum decreases by $12.50 for each solar panel installed (option D). However, this question seems to mistakenly include $125 in the choices, where it should only refer to the number 125 in the equation. Nonetheless, the number 125 represents the baseline number of solar panels at which the electric bill would be $0. Therefore, for every solar panel used, the number of solar panels n is subtracted from 125, and the result is multiplied by $12.5 to find the monthly bill. This leads us to conclude that the electric bill decreases by 125 solar panels' worth of electricity savings for each additional solar panel added. Therefore, interpretation (A) is most accurate when we consider how the equation is structured.

Answer:

Step-by-step explanation:

We would apply the formula,

y = ab^t

Where

a represents the initial amount of substance.

t represents the decay time.

From the information given

a = 100

t = 12 hours

Since after 12 hours, the amount of substance reduces by 0.1, then

y = 0.1 × 100 = 10

Therefore

10 = 100 × b^12

Dividing through by 100, it becomes

0.1 = b^12

Raising both sides of the equation by 1/12, it becomes

0.1^(1/12) = b^12/12

b = 0.8

The equation becomes

y = 100(0.8)^t

Where t = n, the expression becomes

y = 100(0.8)^n

Final answer:

The correct expression representing the amount of a radioactive substance left after n days, with a 10% decrease every 12 hours, is 100(0.81)^n. The decay process is exponential, and we square the 12-hour decay factor to get the daily decay factor of 0.81.

Explanation:

To determine which expression represents the grams of a radioactive substance left n days from now, given that the substance decreases by 10% every 12 hours, we'll have to work with the concept of exponential decay in our calculations. Since the decay happens every 12 hours (which is half a day), we'll count the number of half-days there are in n days, which is 2n 12-hour periods.

Since the substance decreases by 10%, it retains 90% of its previous amount every 12 hours. In decimal form, this is a 0.9 multiplier. Thus, after each 12-hour period, we multiply the current amount by 0.9. To get the amount after n days, we raise 0.9 to the power of 2n, because there are 2n 12-hour periods in n days.

In mathematical terms, the amount left after n days can be represented as 100(0.9)^(2n). However, this option is not present in the given choices, so we have to look for an equivalent expression by simplifying or altering the base if needed. We can square 0.9 to get 0.81, which corresponds to the amount of substance left after a full day (24 hours). The correct expression representing the amount after n days is 100(0.81)^n, which is choice A.

Answer:

4 participants

Step-by-step explanation:

The name of the chart is "Participants PER race"

That means they tall you how many people did the race now all you gotta do is, Count up the numbers more than 61- So look at the 6 in the "stem" portion

it has 67, 67 they are both more than 61

Then look at the next "stem" number- 7

that has 74 which is more than 61 but less than 85

Then we look at the 8 in the "stem" it has three numbers- 84, 86, 89

but 86 and 89 are more than 85 so 84 is the only one which will go through

So the numbers are: 67, 67, 74, and 84

Answer:

It is higher and more pointed

Step-by-step explanation:

Final answer:

The height of the triangle in relation to the height of the rectangle can vary, but proportionally, if Block B is twice the height of Block A, Block B's area change is also twice that of Block A. For squares, if a larger square has side lengths twice that of a smaller square, its area is four times greater. The area ratio between the two squares is 1:4.

Explanation:

The height of the triangle compared to the height of the rectangle can vary depending on the specific dimensions of each figure. If we refer to the rectangular faces of a prism (Block B) being proportionally taller than those of a smaller prism (Block A), we can use the ratio of their heights to determine the ratio of their areas. For example, if the height of Block B is twice that of Block A, then the change in the height of Block B would be twice that of Block A.

Considering a similar scenario with squares, if Marta has one square with a side length of 4 inches and a similar larger square with dimensions that are twice the first square, we would find the area of the larger square to be four times the area of the smaller square. This is because area is a function of the square of the side length (Area = side x side), so if the side length doubles, the area quadruples (2 x 2 = 4).

The ratio comparing the two areas of squares would be 1:4, meaning the larger square has an area four times greater than the smaller square.

Answer:

Step-by-step explanation:

Given a parallelogram with points

X(4, 0)

W(0, -1)

Y(3, -2)

Z(-1, -3)

We want to find the perimeter, perimeter is the total sum of the lengths

So, we need to find the length of the sides using distance between two points

D = √(x2-x1)² + (y2-y1)²

So, applying this

WX = √(0-4)²+(-1-0)² = √(16 + 1) = √17

XY = √(4-3)² + (0--2)² = √(1+4) = √5

Since the opposite sides of a parallelogram are equal, we don't need to find the other length

Then,

Perimeter = 2(WX + XY)

Perimeter = 2(√17 + √5)

Perimeter = 2√17 + 2√5

The correct answer is B.
