Final answer:

To estimate the remaining advertisement budget, calculate the total possible maximum expense and subtract it from the initial budget, resulting in an approximate remaining amount of $14,300.

Explanation:

Mr. Kellen's starting budget for advertisements was $50,000. If I assume that each of the 7 advertisements costs about the maximum amount which is $5,100, the estimated total cost would be 7 times $5,100, which equals $35,700. So, a reasonable estimate of the amount of money remaining after paying for the advertisements is $50,000 - $35,700 = $14,300.

Answer: y= -3/4x + 1

Step-by-step explanation:

use the point to set up slope intercept to find you y-intercept (b)

(8,-5)

y=mx+b

-5=-3/4(8)+b

-5=-6+b

b=1

The equation of the line which passes through the point (8,-5) with a slope of -3/4, when written in slope-intercept form, is y = -3/4x + 1.

The equation of a line in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept. You've been provided that the slope m of the line is -3/4 and it passes through the point (8,-5). You can substitute these values into the formula to find the y-intercept b.

Substituting the given values into the formula gives -5 = (-3/4)*8 + b, which simplifies to -5 = -6 + b. By adding 6 to both sides of the equation, you find that b = 1.

So the equation of the line in slope-intercept form is y = -3/4x + 1.

Answer:

Θ = 45°

BA  = [tex]3\sqrt{2}[/tex] =  4.243

Step-by-step explanation:

i) the given triangle is a right angled isosceles triangle.

ii) the base and the height are both equal. height = base = 3 cm.

iii) from the rule of triangles the sum of all angles in a triangle is 180° and since the triangle is an right angled isosceles triangle one angle is 90° and the other two angles are equal.

 Therefore

Θ° + Θ° + 90° = 180°       ⇒   2Θ° = 180° - 90° = 90°    ∴ Θ = 45°

iv) the hypotenuse BA is given by the Pythagoras' theorem

∴ hypotenuse (BA) = [tex]\sqrt{base^{2} + height^{2} }[/tex] = [tex]\sqrt{BC^{2} + CA^{2} }[/tex]  = [tex]\sqrt{3^{2} + 3^{2} }[/tex] = [tex]3\sqrt{2}[/tex] = therefore BA  = [tex]3\sqrt{2}[/tex] =  4.243

To accurately determine the measure of angle Ø and the length of line BA, specific information or data related to the geometry or vectors involved is required. The measure of angle Ø may be calculated using geometrical principles or trigonometry, and the length of line BA could be determined by measuring or calculation if the context is known.

To find the measure of ∠Ø, you would typically need additional information such as the lengths of the sides of a triangle, the measures of other angles, or the coordinates of points if you are working with a graph. Similarly, to find the measure of line BA, information about the specific triangle, polygon, or coordinate grid where line BA exists is necessary. For example, using the Pythagorean theorem for a right-angled triangle or the distance formula for points on a coordinate grid.

If you are given the lengths of sides or the measures of angles, you can apply geometric principles or trigonometric ratios to calculate the desired measurements. Without the specific data or a provided figure, it's not possible to give an exact answer to these questions.

In the case of vector analysis, as mentioned in the reference provided, to measure line BA you would draw vectors on a graph and construct a parallelogram; the length of the diagonal could then be measured to find the result. For angles, you could use a protractor or apply trigonometric functions if you know the components of the vectors.

Answer:

ok, so write down equation for circumference first, substituting pi symbol with 3.14, and substitute 8 for diameter, because the diameter of the circle and the height of rectangle is the same.

C=3.14×8

C=25.12

then you divide it by 2 because it's only half a circle.

25.12÷2=12.56

Next you find the perimeter of the rectangle

(10×2)+8=28

you dont add the right side,8, because that's where the half circle is. Now you add the half circle and the perimeter of the rectangle.

Answer: 19 /4 or 4 3/4

Step-by-step explanation:

Turn 67/8 into a improper fraction, which is 55/8

Next, also convert 21/8 into an improper fraction, which is 17/8

Next, subtract 17/8 from 55/8 and you should get 38/8

Last, simplify 38/8 to do so divide 38/8 by 4/4 and you should get 19/4 and if you want it's optional to turn it into a mixed number.  

The estimate of the difference between the two fractions is: 4 3/4 = 4.75 ≈ 5.

To find the difference of two fractions means that subtract one from the other.

Thus:

Difference between 6 7/8 and 2 1/8 = 6 7/8 - 2 1/8

Change the mixed fraction to improper fractions

55/8 - 17/8

= (55 - 170/8

= 38/8 = 19/4

= 4 3/4 = 4.75 ≈ 5.

Answer:

[tex]v=\frac{0,25}{\pi } ft/min[/tex]

Step-by-step explanation:

There is a relation with the initial and final dimensions of the hopper according to the sand level when its high is 6 feet as follows:

[tex]\frac{h_{1} }{h_{2} }=\frac{r_{1} }{r_2}\\{r_2}=\frac{12ft*6ft}{18ft}\\ r_2=4ft[/tex]

Where the calculated [tex]r_{2}[/tex] is given with the 6 feet hgh.

Then we have the sand flow formula which is:

[tex]Q=A*v[/tex]

Where A represents the area of the transversal section and v  the velocity that we need to know, the area is:

[tex]A=\pi r^{2}\\ A=\pi *4^{2}\\ A=16\pi ft^{2}[/tex]

And finally the sand is dropping when the level is 6 feet high with the velocity (v) :

[tex]v=\frac{Q}{A} \\v=\frac{4}{16\pi }[/tex]

[tex]v=\frac{0.25}{\pi } ft/min[/tex]

The sand level in the hopper is dropping at a rate of approximately 0.08 feet per minute when the sand level is 6 feet high. This is calculated using related rates and the volume formula for a cone. The relationship between radius and height, derivative calculations, and the given sand emptying rate are essential for this solution.

To determine how fast the level of sand is dropping in the hopper, we need to use related rates. The volume V of the sand in the inverted cone is given by the formula:

V = (1/3)πr2h

In this case, the radius r and height h of the sand level are proportional because the shape is a cone. We can express the radius r in terms of the height h using similar triangles. Given the overall height is 18 feet and the radius is 12 feet, we have:

r = (12/18)h or r = (2/3)h

Substituting r into the volume formula:

V = (1/3)π[(2/3)h]2h = (4/27)πh3

We need the rate of change of the height (dh/dt) when h = 6 feet. Given dV/dt = -4 ft³/min (negative because the volume is decreasing), we use the chain rule for differentiation:

dV/dt = (dV/dh)(dh/dt)

First, find dV/dh:

dV/dh = d/dh [(4/27)πh3] = (4/27)π × 3h2 = (4/9)πh2

Using dV/dt = -4 ft³/min:

-4 = (4/9)π(h2)(dh/dt)

When h = 6 feet:

-4 = (4/9)π(62)(dh/dt)

-4 = (4/9)π(36)(dh/dt) = 16π(dh/dt)

Therefore:

dh/dt = -4/16π = -1/4π

dh/dt = -0.08 feet/min

So, the level of sand is dropping at a rate of approximately 0.08 feet per minute when the sand level is 6 feet high.

The solution to the system of equations is x = 0 and y = -3.

To solve the system of equations:

1. 6x - 5y = 15

2. x = y + 3
