The net torque about the axle is zero, as no external forces are acting on the disk.  Since there are no external forces acting on the disk, the sum of all the torques must be zero. Therefore, the net torque about the axle is zero.

The net torque about the axle is calculated by summing up all the torques about the axle due to external forces. Since there are no external forces acting on the disk, the sum of all the torques must be zero. Therefore, the net torque about the axle is zero.

The net torque about the axle of the 16-cm diameter disk in is zero, since there are no external forces acting on the disk. To calculate the net torque about the axle, we need to take the sum of all the torques about the axle due to external forces. Since there are no external forces, this sum must be zero. This means that the net torque about the axle is zero. This is because there is no force causing the disk to rotate and therefore, the net torque about the axle must also be zero. This result is consistent with the law of conservation of angular momentum, which states that when no external forces are acting on an object, the total angular momentum of the system must remain constant. Thus, the net torque about the axle of the 16-cm diameter disk in is zero.

Answer:

They are not in the same location

Step-by-step explanation:

Well because we have x axis and y axis, x always has to go first. In (2, 5) 2 is first and has to start from the x axis and 5 is the y axis. And the (5,2) is the opposite and the places would be in totally different places on the coordinate plane.

Answer: No

Step-by-step explanation: The order of coordinates for a given point is very important. For example, (2, 5) and (5, 2) represent two very different points on a coordinate system, as shown in the picture below.

A given point, such as (2, 5), is often reffered to as

an ordered pair because the order of coordinates is very important.

The value of x that makes the line containing (1,2) and (5,3) perpendicular to the line containing (x,4) and (3,0) is x = 2.

To determine the value of x such that the line containing (1,2) and (5,3) is perpendicular to the line containing (x,4) and (3,0), we need to find the slope of both lines and apply the concept of perpendicular lines.

The slope of a line can be found using the formula:

slope = (change in y) / (change in x)

For the line containing (1,2) and (5,3), the slope is:

slope1 = (3 - 2) / (5 - 1) = 1 / 4

To find the slope of the line containing (x,4) and (3,0), we use the same formula:

slope2 = (0 - 4) / (3 - x) = -4 / (3 - x)

Perpendicular lines have slopes that are negative reciprocals of each other. In other words, if the slope of one line is m, then the slope of a line perpendicular to it is -1/m.

So, we can set up the equation:

-1 / (1/4) = -4 / (3 - x)

Simplifying this equation:

-4 = -4 / (3 - x)

To remove the fraction, we can multiply both sides by (3 - x):

-4(3 - x) = -4

Expanding and simplifying:

-12 + 4x = -4

Adding 12 to both sides:

4x = 8

Dividing both sides by 4:

x = 2

Proportionately, the number of cups of strawberries that Maria needs to use is 3¹/₈ cups.

Proportion refers to a part of a whole.

Proportion is a ratio of one value to another.

Proportions are depicted as decimals, fractions, or percentages.

In this situation, we know that the amount of strawberries is a fractional value of the combined fruits.

Thus, we can multiply the fraction of strawberries against the combined value of the other fruits to determine the number of cups of strawberries needed.

Kind of Fruit       Amount

Grapes               3²/₃ cups

Melon                 2¹/₄ cups

Pineapple          2³/₄ cups

Total of other fruits = 8²/₃ cups

Strawberries             ?

Strawberries = 3¹/₈ (8²/₃ x ³/₈)

Thus, Maria needs 3¹/₈ cups of strawberries.

\(\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}\)

\(x=2,\:y=1\)

Step-by-step explanation:

Given the equations

\(-5x-18y=-28\)

\(-10x+9y=-11\)

solving the system of the equation by elimination method

\(\begin{bmatrix}-5x-18y=-28\\ -10x+9y=-11\end{bmatrix}\)

\(\mathrm{Multiply\:}-5x-18y=-28\mathrm{\:by\:}2\:\mathrm{:}\:\quad \:-10x-36y=-56\)

\(\begin{bmatrix}-10x-36y=-56\\ -10x+9y=-11\end{bmatrix}\)

\(-10x+9y=-11\)

\(-\)

\(\underline{-10x-36y=-56}\)

\(45y=45\)

\(\begin{bmatrix}-10x-36y=-56\\ 45y=45\end{bmatrix}\)

solve 45y=5 for y:

\(45y=45\)

\(\frac{45y}{45}=\frac{45}{45}\)

\(y=1\)

\(\mathrm{For\:}-10x-36y=-56\mathrm{\:plug\:in\:}y=1\)

solve \(-10x-36\cdot \:1=-56\) for x:

\(-10x-36\cdot \:1=-56\)

\(-10x-36=-56\)

Add 36 to both sides

\(-10x-36+36=-56+36\)

\(-10x=-20\)

14.45 = 14.5 = 15     8.05=8

Step-by-step explanation:

When rounding use the rule "5 or more raise the score, 4 or less let it rest." We round 14.45 to 14.5 because .45 will round to .50. We are left with 14.50. The .50 rounds the 14 to 15. For 8.05 because there is a 0 before the 5 we leave the number at 8.

The mixture must be heated an amount of 23 °F to reach a temperature of 132 °F.

Temperature is the measure of how "hot" a system is. Physically speaking, temperature is closely related to atomic and molecular motion within a system. In this problem we find a mixture that must be at a certain temperature, higher than its real one.

Therefore, the amount required to increase the temperature of the mixture is defined by following subtraction:

ΔT = R - r

Where:

If we know that r = 109 °F and R = 132 °F, then the temperature difference is:

ΔT = 132 °F - 109 °F

ΔT = 23 °F

Step-by-step explanation:

The value of the quotient expression x + 4 /x 2 ÷ 2 x is (2x + 8)/x

The quotient expression is represented as:

x + 4 /x 2 ÷ 2 x

Rewrite the expression properly, as follows:

(x + 4)/(x^2 ÷ 2x)

Divide x^2 and 2x by x

So, we have:

(x + 4)/(x ÷ 2)

Express  x ÷ 2 as a fraction

(x + 4)/(x/2)

Express the expression as a product

(x + 4) * 2/x

Evaluate the product

(2x + 8)/x

Answer: B

Step-by-step explanation:

A) \(a^\frac{3}{4}\)÷\(a^\frac{1}{2}\) cannot be the answer. When a to the power of x is divided by a to the power of y it is a to the power of x-y. Ex: \(a^x\)÷\(a^y=a^x^-^y\)

So 3/4-1/2 is 1/4 giving us \(a^{\frac{1}{4} }\)

B is the answer because taking the square root of a is the same as \(a^\frac{1}{2}\) which isn't the same as \(a^\frac{1}{4}\)

C is not the answer because when a to the power of x is multiplied by a to the power of y it is a to the power of x+y. Ex:  \(a^x\)·\(a^y\)=\(a^{x+y}\)

1/8+1/8=1/4 so it is \(a^\frac{1}{4}\)

D can't be the answer. \(a^\frac{1}{8}\) squared is the same as \(a^\frac{1}{8}\)·\(a^\frac{1}{8}\) so the same explanation of c applies to d

There is approximately a 36.11% probability of rolling an odd sum or doubles when a pair of dice is rolled.

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.

There are 3 odd numbers among the possible outcomes of each die (1, 3, 5), so there are 3 x 3 = 9 ways to obtain an odd sum:

(1,2), (1,4), (1,6), .... (6,1), (6,3), (6,5)

There are 6 possible outcomes for rolling the same number on both dice, so there are 6 ways to obtain doubles:

(1,1), (2,2), (3,3), (4,4), (5,5), (6,6)

We counted (1,1), (3,3), and (5,5) twice in the above two categories, so we need to subtract 2 from the total count.

Therefore, there are 9 + 6 - 2 = 13 ways to obtain an odd sum or doubles.

Therefore, the probability of rolling an odd sum or doubles is:

P(odd sum or doubles) = 13/36

Thus, there is about a 36.11% probability of rolling an odd sum or doubles when a pair of dice is rolled.

Answer:

c = 60.65 cm

Step-by-step explanation:

Given that,

The two sides of a triangle are 33 cm and 37 cm.

The angle between these two sides is 120°.

We need to find the length of the third side of the triangle. Let c is the third side. Using cosine rule,

\(c^2=a^2+b^2-2ab\cos C\)

a = 33 cm, b = 37 cm and C is 120°

So,

\(c^2=(33)^2+(37)^2-2\times 33\times 37\cos (120)\\\\c=60.65\ cm\)

So, the length of the third side of the triangle is 60.65 cm.
