Check the value of the remainder:

If the remainder is less than 2.5, round down to the nearest multiple of 5

If the remainder is 2.5 or greater, round up to the nearest multiple of 5

Rounding off 7234 to the nearest 5 means we need to find the multiple of 5 that is closest to 7234.

Divide 7234 by 5 and get the quotient and remainder

= 7234 ÷ 5

= 1446 with a remainder of 4

Multiply the quotient by 5 and add the value determined.

Using this method, we can see that the nearest multiple of 5 to 7234 is 7235, since the remainder is 4 which is less than 2.5. Therefore, rounding off 7234 to the nearest 5 results in 7235.

The angles on the diagram are vertical angles and the value of x is 25.

The two angles are said to be adjacent angles when they have a common vertex and side.

On the other hand, vertical angles are angles that are opposite of each other when two lines cross and they are conguent.

Therefore, the angles on the diagram are vertical angles.

Now, since vertical angles are congruent.

Angle 75 and angle (4x - 25 ) are equal.

Hence;

4x - 25 = 75

Solve for x

4x - 25 = 75

Add 25 to both sides

4x - 25 + 25 = 75 + 25

4x = 75 + 25

4x = 100

Divide both sides by 4

4x/4 = 100/4

x = 100/4

x = 25

Therefore, the value of x is 25.

The Area of Garden is 62/3 feet².

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape.

The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares that cover a closed figure's surface is its area. Square units like cm² and m² are used to measure area. A shape's area is a two-dimensional measurement.

Given:

Length = 7 3/4 feet = 31/4 feet

In response to the aforementioned query, we may say that The interest for the previous month, rounded to the nearest cent, is $289.84.

By dividing the principal by the interest rate, the passage of time, and other factors, simple interest is determined. Simple return equals principle plus interest plus hours is the formula used in marketing. The easiest way to compute interest is by using this method. The most typical method for calculating interest is as a portion of the principle amount. For example, if he borrows $100 from a buddy and agrees to pay back the loan at 5% interest, he will only pay his share of the 100% interest. $100 (0.05) = $5. When you borrow money, you must pay interest, and you must charge interest when you lend it. Typically, interest is determined as an annual percentage of the loan total. The loan's interest is the name given to this percentage.

The Annual Percentage Rate (APR) can first be changed to a monthly interest rate as follows:

r = APR/12 = 0.085/12 = 0.0070833

Then, we may determine how many months the loan will last:

n = 2.5 years * 12 months a year = 30 months.

We can now calculate the total amount owing at the conclusion of the loan term using the compound interest formula:

A= P(1 + r)^n

where P is the loan's principle, r is the interest rate each month, and n is the number of months.

A = $3000(1 + 0.0070833)^30\s= $3,789.64

At the conclusion of the loan period, there will be a balance of $3,789.64.

B = $3000(1 + 0.0070833)^(30-1) - [((1 + 0.0070833)^30 - 1)/(0.0070833)]

= $3,499.80

I = $3,789.64 - $3,499.80\s= $289.84

The interest for the previous month, rounded to the nearest cent, is $289.84.

The radius of the circle E is 27/5.

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

Let X be the intersection of the circles with centers B and E, and Y be the intersection of the circles with centers C and E.

Since the radius of B is 3, AX = 4.

Assume AE = p.

Then EX and EY are radii of circle E and have length 4 + p.

AC = 8, and ∠CAE = 60° because we are given that triangle T is equilateral.

Using the Law of Cosines on Δ CAE, we obtain

(6+p)² =p² + 64 - 2(8)(p) cos 60

The 2 and the cos 60 terms cancel out:

p² + 12p + 36 = p² + 64 - 8p

12p+ 36 = 64 - 8p

p = 28/20

= 7/5

The radius of circle E is 4 + (7/5)

The equation for the function with the described transformations is y(x) = -2f(x+1) + 8.

Starting with the basic function of f(x), we can apply the described transformations in the following order:

Vertical stretching by a factor of 2: We multiply the output of the function by 2. This results in a new function g(x) = 2f(x).

Reflection across the x-axis: We flip the sign of the output of the function. This results in a new function h(x) = -g(x) = -2f(x).

Translation 1 unit left and 8 units up: We shift the graph of the function 1 unit to the left and 8 units up. This can be achieved by replacing x with (x+1) and adding 8 to the output.

This results in a new function y(x) = h(x+1) + 8 = -2f(x+1) + 8.

What is right angled triangle ?

A right-angled triangle is a triangle that has one angle that measures 90 degrees (a right angle). This means that the other two angles must add up to 90 degrees as well. The side opposite the right angle is called the hypotenuse, and the other two sides are called the legs. The Pythagorean theorem, which states that the sum of the squares of the legs of a right-angled triangle is equal to the square of the hypotenuse, is a fundamental concept in mathematics and has many practical applications. Right-angled triangles are used in fields such as engineering, architecture, and physics to calculate distances, heights, and angles.

a) Let's use the Pythagorean theorem to find the altitude of the plane. We have a right triangle with the slant range as the hypotenuse, the ground range as one leg, and the altitude as the other leg. So, we can use:

altitude² + ground range² = slant range²

altitude² + 10.15² = 14.5²

altitude² = 14.5² - 10.15²

altitude² = 84.9025

altitude ≈ 9.21 km or 9210 meters (rounded to the nearest meter)

b) If the plane descends at a rate of 750 meters per minute, the pilot will have:

time = altitude / descent rate

time = 9210 / 750

time ≈ 12.28 minutes (rounded to two decimal places).

Therefore, the altitude of the plane to the nearest meter is 9210 meters and if the plane descends at a rate of 750 meters per minute, the pilot will have 12.28 minutes.

Step-by-step explanation:

If Sara is making 3 batches of chocolate chip cookies using 2 1/4 cups of flour per batch, then the total amount of flour she uses for the chocolate chip cookies is:

3 batches x 2 1/4 cups per batch = 6 3/4 cups of flour

Since she will use 12 3/4 cups of flour for all six batches, the amount of flour used for the oatmeal cookies can be found by subtracting the amount of flour used for the chocolate chip cookies from the total amount of flour:

12 3/4 cups - 6 3/4 cups = 6 cups

To determine how many cups of flour are needed for each batch of oatmeal cookies, we can divide the total amount of flour used for the oatmeal cookies by the number of batches:

6 cups ÷ 3 batches = 2 cups per batch

Therefore, the equation that can be used to determine how many cups of flour are needed for each batch of oatmeal cookies is:

Flour needed per batch of oatmeal cookies = Total flour needed for oatmeal cookies ÷ Number of oatmeal cookie batches

Or, in this case:

Flour needed per batch of oatmeal cookies = 6 cups ÷ 3 batches = 2 cups per batch.

The solution to the system of inequalities is:

{x | x ≥ -2, x - y ≥ 1} or in set-builder notation: {(x,y) | x ≥ -2, y ≤ x - 1}.

A linear inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

First, let's graph the line x = -2, which is a vertical line passing through -2 on the x-axis.

Next, let's graph the line x - y = 1, which can be rewritten as y = x - 1. This is a line with a slope of 1 (meaning it goes up 1 unit for every 1 unit it goes to the right) and a y-intercept of -1 (meaning it passes through -1 on the y-axis).

Now, we need to shade in the region that satisfies both inequalities. We know that x has to be greater than or equal to -2, so we shade to the right of the vertical line x = -2. We also know that x - y has to be greater than or equal to 1, so we shade above the line y = x - 1.

The shaded region is the overlapping region that satisfies both inequalities. It is the region above the line y = x - 1 and to the right of the vertical line x = -2.

Therefore, the solution to the system of inequalities is:

{x | x ≥ -2, x - y ≥ 1} or in set-builder notation: {(x,y) | x ≥ -2, y ≤ x - 1}.

Let's make,

mechanic #1's rate = x

mechanic #2's rate = y

Their rate is dollars per hour ($/hr)

Mechanic #1 worked for 20 hours (hr × $/hr = $)

20x = money earned by mechanic #1

And mechanic #2 worked for 15 hours

15y = money earned by mech#2

Together they charged a total of $2175. So the amount of money earned by both mechanics.

20x + 15y = 2175

The sum of the two rates was $120 per hour.

x + y = 120

which means

x = 120- y

Putting (120 - y) in for "x" in the other equation to get everything in terms of one variable.

20(120 - y) + 15y = 2175

Now we can solve for y and get the solution:

20(120 - y) + 15y = 2175

y=45 $/hr

Now use this to solve for x
