2(5+3(10+5(12-3))) como la resuelvo?

Answer:

Step-by-step explanation:

The volume of a cone can be calculated as (1/3)πr^2h, so we can set that equal to 43.98:

(1/3)πr^2h = 43.98

Dividing both sides by (1/3)π:

r^2h = 43.98 * 3 / π

Solving for one of the variables in terms of the other requires choosing specific values for either radius or height. Here are two examples:

Example 1: Let's say r = 3.

Then

h = 43.98 * 3 / (π * 9) = 4.43

So one possible cone has height 4.43 and radius 3.

Example 2: Let's say h = 5.

Then

r^2 = 43.98 * 3 / (π * 5) = 25.51

So one possible cone has height 5 and radius 5.07.

There are 56 possible ways to make a selection of coins so that the value is at least 25 cents.

The total number of possible ways to make a selection of coins so that the value is at least 25 cents is calculated using the formula:

# of ways = (n+r-1Cr-1)

Where n is the number of coin denominations available and r is the number of coins needed to make the selection.

In this case, n = 5 (1 cent, 5 cents, 10 cents, 25 cents, 50 cents) and r = 4. Therefore, the number of ways to make a selection of coins so that the value is at least 25 cents is calculated as:

of ways = (5+4-1C4-1)

of ways = (8C3)

of ways = 56

Therefore, there are 56 possible ways to make a selection of coins so that the value is at least 25 cents.

Answer:

V = πr^2h = πr^2(2r) = 2πr^3

Volume of the cone: The volume of a cone with height h and base radius r is given by the formula V = (1/3)πr^2h. In this case, the height of the cone is equal to the radius of the hemisphere, so h = r. Substituting this into the formula, we have:

V = (1/3)πr^2h = (1/3)πr^2r = (1/3)πr^3

Volume of the hemisphere: To estimate the volume of the hemisphere, we'll average the volumes of the cylinder and cone.

So:V = (2πr^3 + (1/3)πr^3) / 2 = (5/3)πr^3 / 2 = (5/6)πr^3

So the volume of the hemisphere is approximately equal to (5/6)πr^3, where r is the radius of the hemisphere (and equal to the radius of the cylinder).

The probability that Nomusa will not take two of the same type of sweet is 0.35

To find the probability that Nomusa will not take two of the same type of sweets, we need to find the total number of combinations of two sweets she can take, and then find the number of combinations where the two sweets are different.

First, let's find the total number of combinations of two sweets:

C(30, 2) = 435

This means there are 435 different combinations of two sweets she can take from her collection of 30 sweets.

Next, let's find the number of combinations where the two sweets are not the same:

C(18, 2) + C(7, 2) + C(5, 2) = 153

This means that there are 153 combinations where the two sweets are different fruit sweets, different aniseed sweets, or different mint sweets.

So, the probability that Nomusa will not take two of the same type of sweet is:

153 / 435 = 0.35

This means that there is a 35% chance that the two sweets she takes will not be the same type of sweet.

The solution to the system of linear equations using the Equal Value Method is Y = -(8y / 6) - 21.

The Equal Value Method is a technique used to solve a system of linear equations. To solve a system of linear equations using the Equal Value Method, we first write out the two equations. In this case, we have the two equations:

Y = -8x - 21

y = 6x + 7

Next, we need to solve one of the equations for one of the variables. We can solve for x in the first equation, giving us x = (-21 - Y) / -8. We can then substitute this into the second equation, giving us y = (6(-21 - Y) / -8) + 7. We can then expand and simplify this equation, giving us y = (126 + 6Y) / -8.

Finally, we can set the two equations equal to each other and solve for Y. This will give us 126 + 6Y = -8y, which simplifies to 6Y = -8y - 126. We can then divide both sides by 6 to get Y = -(8y / 6) - 21.

Therefore, the solution to the system of linear equations using the Equal Value Method is Y = -(8y / 6) - 21.

The expression used by commutative property of addition and the associative property of multiplication to rewrite the expression (3x2) x 5+7 is 7+3.(2.5).

The commutative property or commutative law of mathematics states that while executing mathematical operations, the order of terms is irrelevant.

Only addition and multiplication operations are under the purview of the commutative property. As a result, it means that while adding or multiplying any two integers, we can swap the positions of the numbers. One of the main characteristics of integers is this.

According to the commutative property of multiplication, even if the positions of the two integers are switched around, the result of multiplying two integers will still be the same.

Components of the unit vector are (cos(156), sin(156)) = (-0.41, 0.91). Drawing a vector with a positive y-component and an angle of 156 degrees with the x-axis in the xy plane will help you see it.

The unit vector has a positive y component and is located in the xy plane at a 156 degree angle to the x axis. Drawing a vector with a positive y-component and an angle of 156 degrees with the x-axis in the xy plane will help you visualise this. Components of the unit vector are (cos(156), sin(156)) = (-0.41, 0.91). This shows that the unit vector has both a positive y-component and a negative x-component. Since the unit vector's magnitude is 1, it has a length of 1, and it points in the same general direction as the 156-degree angle. In light of this, the unit vector is (-0.41, 0.91). Any vector with the same magnitude and direction as the unit vector but a different length can be represented by this vector.

The graph of a parabola is a u (or n) shaped curve obtained by the intersection of a cone and a plane which is parallel to the slant of the cone.

The x-intercepts are the point the graph intersects the x-axis, where the y-value is zero, y = 0. From the graph, the x-intercepts are;(-1, 0), and (3, 0)

The y-intercept is the point at which the graph intersects the y-axis, which is the point the x-value is 0, (x = 0). The graph indicates that the y-intercept is (0, 3)

The vertex of the parabolic graph is the highest (or lowest) point on the graph, therefore, from the graph in the question, the vertex point is; (1, 4)

The axis of symmetry is the line that divides the graph into two mirror halves, which is the line passing through the vertex and parallel to the y-axis. The axis of symmetry is therefore the line; x = 1

The domain is the set of the possible input values of the graph of the function, which is the set of the possinble x-values.

The graph indicates that the x-values can decrease and increase to -∞ and ∞. The domain is therefore; (-∞, ∞).

The region where the graph is increasing is fro x = -∞ to just before x = 1. The interval where the graph is increasing is therefore; (-∞, 1)

Similarly, the interval the graph is decreasing is; (4, ∞)

The graph is positive in the region above the x-axis. The interval over which the graph is positive is therefore between the x-intercepts, which is; (-1, 3)

The graph is negative in the region below the x-axis. The interval in which the graph is negative are; (-∞, 1), and (3, ∞)

The perimeter of scale drawing of rectangular classroom floor is 42 inches.

Based on the mentioned information, let us first calculate the width of floor of classroom according to the scale drawing.

Length/width of original classroom floor = length/width of scale drawing

30/33 = 10/width

As we know, 1 foot = 12 inches

So, length = 360 inches and width = 396 inches

Width = (396 × 10)/360

Cancelling zero as it is common in both numerator and denominator

Width = 396/36

Performing division on Right Hand Side of the equation

Width = 11 inches

Perimeter of scale drawing = 2 (length + width)

Perimeter = 2( 10 + 11)

Performing addition

Perimeter = 2 × 21

Performing multiplication

Perimeter = 42 inches

Thus, perimeter of the rectangle is 42 inches.
