An equation is a mathematical statement that asserts that two expressions are equal. An equation consists of two sides, the left-hand side and the right-hand side, separated by an equal sign (=).

For example, 2x + 5 = 11 is an equation, where the left-hand side is 2x + 5 and the right-hand side is 11. This equation asserts that the expression 2x + 5 is equal to 11, and the value of x can be determined by solving for x.

Equations can be simple or complex, and they can involve one or more variables. They can also be linear or nonlinear, depending on the nature of the expressions involved.

Solving an equation involves finding the values of the variables that make the equation true. This may involve applying algebraic operations and simplification techniques to isolate the variable on one side of the equation.

Equations are used in many areas of mathematics, science, engineering, and economics, and they provide a powerful tool for modeling and analyzing real-world situations. They are also used extensively in computer programming and cryptography, where they play a critical role in the development of algorithms and data encryption methods.

We have the equation [tex]h = 94 - 16t^2[/tex], where h is the height of the toy car in feet and t is the time in seconds.

When the toy car reaches the bottom floor, its height will be h = 0. So we can set the equation equal to 0 and solve for t:

[tex]0 = 94 - 16t^216t^2 = 94t^2 = 94/16[/tex]

[tex]t = \sqrt{(94/16)} = \sqrt{(23.5/4)} = 2.43 seconds[/tex] (rounded to two decimal places)

Therefore, it takes the toy car 2.43 seconds to fall to the bottom floor.

The closest answer choice is B. 9/4 seconds, which is equal to 2.25 seconds.

Answer:

the diameter of the largest circle is 2r = 56/3 cm.

Step-by-step explanation:

Let the largest circle have center O and radius r. Join P, Q, R and O as shown in the figure below.

Since the circle with center Q and the circle with center R touch each other externally, the distance between their centers is the sum of their radii. Therefore,

QR = QM + MR

where M is the point of contact of the two circles. Similarly, since the circle with center P touches the circle with center Q externally, the distance between their centers is the sum of their radii. Therefore,

PQ = PM + MQ

Adding these two equations, we get

PQ + QR = PM + MQ + QM + MR

Substituting the given values, we get

10 + 12 = PM + MQ + 12 + 8

or PM + MQ = 2

Now consider the right-angled triangle PQO. Since PQ is the tangent to the circle with center P at point A, OA is perpendicular to PQ. Similarly, OQ is perpendicular to QR and OR is perpendicular to RP. Therefore, angles PAO, QBO and ROC are all right angles.

Let the perpendicular from O to PQ meet PQ at X. Then PX = OQ - PQ/2 = r - 5. Similarly, let the perpendicular from O to QR meet QR at Y. Then QY = OR - QR/2 = r - 6. Let the perpendicular from O to RP meet RP at Z. Then RZ = OP - PR/2 = r - 4.

Now consider the right-angled triangle OXY. Using the Pythagorean theorem, we get

OX^2 = OY^2 + XY^2

Substituting the values of OY and XY, we get

(r - 6)^2 = (r - 5)^2 + (r - 4)^2

Expanding and simplifying, we get

3r^2 - 56r + 191 = 0

Solving this quadratic equation, we get two solutions: r = 7 and r = 28/3. Since the radius of the largest circle cannot be less than the radius of the circle with center Q, which is 6, the only possible solution is r = 28/3.

Therefore, the diameter of the largest circle is 2r = 56/3 cm.

I. The correct statement is: m<AOB = m<BOC

The measures of the angles are:

II. m<BOC = 53 degrees.

III. m<AOC = 106 degrees.

When a segment bisects an angle, it forms two equal angles. Therefore, we have following which explains how to find the measure of the given central angle.

I. <AOC is bisected by segment OB into: AOB and BOC, which are equal. Therefore:

m<AOB = m<BOC

II. m<AOB = 53 degrees, therefore,

m<BOC = 53 degrees.

III. m<AOC = 2(53)

m<AOC = 106 degrees.

Answer: C

Step-by-step explanation:

Option C is correct, the volume of the tank is 353 cubic feet.

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

The volume of a cylindrical tank is given by the formula:

V = πr²h

where r is the radius of the tank and h is its height.

We know that the tank has a circumference of approximately 31.4 feet, which means:

2πr = 31.4

Dividing both sides by 2π, we get:

r = 31.4/(2π) ≈ 5

So, the radius of the tank is approximately 5 feet.

By given height of the tank is 4.5 feet.

Substituting these values into the formula for the volume of a cylinder, we get:

V = π(5)²(4.5) = 353.4

Therefore, the volume of the tank is 353 cubic feet.

Answer:

See below

Step-by-step explanation:

The linear function is to be expressed in slope-intercept form:

y = mx + c

where:              

                           m = slope

                               = [tex]\frac{y_{2} -y_{1}}{x_{2} -x_{1}}[/tex]

           Select a pair of x and y coordinates of two points along this graph

e.g (0,1) and (5,0):

                          m = [tex]\frac{(0 - 1)Percent InDecimal}{(5 - 0) hour}[/tex]

                              = [tex]\frac{-1}{5}[/tex]

       ∴ slope = [tex]-\frac{1}{5}[/tex] = [tex]-0.2\frac{PercentInDecimal}{hour}[/tex]

  which means 0.2 × 100%= 20%

∴The slope indicates that the power decreases by 20% per hour

                          c = y-intercept:

   It is the y-value AT which the graph cuts or meets the y-axis. Its corresponding x-coordinate is 0. The y-intercept can be either read directly from the graph or calculated mathematically

       ∴y-intercept = 1

In this scenario, the y-intercept indicates the initial value or the value present in the beginning.
which means 1.0 × 100% = 100%
∴The y-intercept indicates that the battery is at 100% when you turn on the laptop.

∴Linear function relating y to x:

Substituting the values of m and c into the above stated equation:

     [tex]y = -\frac{1}{5}x + 1[/tex]

The x-intercept is the x-value at which the graph crosses or intersects the x-axis. It’s corresponding y-coordinate is zero.

     x-intercept = 5

In this scenario, the x-intercept indicates the point at which the final value is reached or achieved.

∴ The x-intercept indicates that the battery lasts 5 hours.

The battery power is at 75% = [tex]\frac{75}{100}[/tex] = 0.75 (expressed in decimal form. This means y = 0.75, which is to be substituted into the above derived linear function to solve for the corresponding value of x:

[tex]0.75 = -\frac{1}{5}(x) + 1[/tex]

Rearrange the equation to isolate x and make it the subject of the equation:

[tex]\frac{1}{5}x = 1 - 0.75[/tex]

[tex]\frac{1}{5}x = 0.25[/tex]

Cross-multiplication is applied:

[tex](1)(x) = (5)(0.25)[/tex]

x = 1.25 hours

∴The battery power is at 75% after 1.25 hours

Answer:

Step-by-step explanation:

Newton's first law of motion, also known as the law of inertia, states that an object at rest will remain at rest, and an object in motion will continue in motion with a constant velocity, unless acted upon by an external force.

If you are standing on separate sheets of paper and start running, your body will experience a forward motion. However, the sheets of paper under your feet will initially resist the motion due to friction. The force of friction will create an equal and opposite force, causing the sheets of paper to slide backwards. As you continue to run, the friction between your feet and the paper will decrease, and the sheets of paper may eventually stop sliding and you will continue running with a constant velocity.

This is an example of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. The force you apply to the ground when running is the action, and the force of the ground pushing back on you is the reaction.

Answer:

Step-by-step explanation:

the APR for this loan is approximately 14.27%.

To find the APR for this loan, we can use the formula:

APR = (2 * n * F) / (P * (n + 1))

where:

n = number of payments (24 in this case)

F = finance charge per $100 financed ($11.45 in this case)

P = amount financed per $100 (which we don't know yet)

We need to solve for P to be able to use the formula. We know that the finance charge is $11.45 for every $100 financed, so we can set up the equation:

11.45 = F / P

where F is the finance charge per $100 financed and P is the amount financed per $100.

Solving for P, we get:

P = F / 11.45

P = 100 * (11.45 / 100)

P = $1,000

So the amount financed is $1,000.

Now we can substitute the values into the APR formula:

APR = (2 * n * F) / (P * (n + 1))

APR = (2 * 24 * 11.45) / (1000 * (24 + 1))

APR = 0.1427 or 14.27%

Step-by-step explanation:

To find the proportion of cities with a vacancy rate of more than 9%, we need to add the relative frequencies for the classes with vacancy rates greater than 9%. These classes are 9 < x ≤ 12 and 12 < x ≤ 15.

Proportion of cities with a vacancy rate of more than 9%:

= Relative frequency for 9 < x ≤ 12 + Relative frequency for 12 < x ≤ 15

= 0.24 + 0.42

= 0.66

Therefore, 66% of the cities had a vacancy rate of more than 9%.

Rounding this answer to two decimal places, we get 0.66 as the final answer.

the sale price of a fishing rod is $28.16.

How to do?

The markup of 220% means the store sells the rods for 100% + 220% = 320% of the cost price.

So, the selling price of one fishing rod before the discount is:

320% of $11 = (320/100) x $11 = $35.20

Now, the rods are marked down by 20%, which means the selling price is reduced by 20% of $35.20:

20% of $35.20 = (20/100) x $35.20 = $7.04

Therefore, the sale price of one fishing rod after the 20% discount is:

$35.20 - $7.04 = $28.16

So, the sale price of a fishing rod is $28.16.
