Answer:

30 players.

Step-by-step explanation:

3 rows of 8 = 3 x 8 = 24. Plus an additional 6 players in the fourth row. 24 + 6 = 30.

The team photo consists of 30 players: 24 in the three full rows, each with 8 players, and 6 more players in the fourth row.

To find the total number of players in the team photo, you can simply add the number of players in each row together. In this case, there are three rows of 8 players each and a fourth row with 6 players.

First, calculate the total number of players in the three full rows, where each row has 8 players:

3 rows x 8 players/row = 24 players

Now, add the players from the fourth row:

24 players (from the full rows) + 6 players (from the fourth row) = 30 players

So, there are 30 players in the team photo.

In summary, the team photo includes 30 players, with 24 players in the three full rows of 8 each and an additional 6 players in the fourth row.

Answer:

The equation which is equivalent to [tex]t^2-8t+15=0[/tex] is

[tex](t-3)(t-5)=0[/tex]

Step-by-step explanation:

Given that the time a projectile spends in the air can be modeled by the equation [tex]t^2-8t+15=0[/tex], where t represents the amount of time traveled in seconds.

To find the equation is equivalent to  [tex]t^2-8t+15=0[/tex] :

[tex]t^2-8t+15=0[/tex]

[tex]t^2-3t-5t+15=0[/tex]

[tex]t(t-3)-5(t-3)=0[/tex]

[tex](t-3)(t-5)=0[/tex]

Therefore the equation which is equivalent to  [tex]t^2-8t+15=0[/tex] is

[tex](t-3)(t-5)=0[/tex]

Final answer:

The equivalent equation to the quadratic equation representing the time a projectile spends in the air, t² -8t + 15 = 0, is (t - 3)(t - 5) = 0, which results from correctly factoring the original equation.

Explanation:

The time a projectile spends in the air is represented by the quadratic equation t² -8t + 15 = 0. To find an equivalent equation, we must factor the quadratic equation correctly. The correct factored form that corresponds to the original equation is (t - 3)(t - 5) = 0, based on the rules of factoring quadratics and finding roots that sum up to -8 (the coefficient of t) and multiply to 15 (the constant term).

The process of factoring involves finding two numbers that add up to the coefficient of the linear term (-8 in this case) and multiply to the constant term (15 here). The numbers -3 and -5 satisfy both these conditions as (-3) + (-5) = -8 and (-3) × (-5) = 15. Therefore, the equivalent equation is (t - 3)(t - 5) = 0.

The lot costs 5000 dollars.

Step-by-step explanation:

The cost of a House and the lot = $40,000.

Let us assume the cost of lot as 'x'

Given that, The cost of the house is 7 times as much as the lot.

Therefore, The cost of the house= 7x

The cost of both the house and the lot= x + 7x

$40,000 = x + 7x

40,000 = 8x

x = 40,000/8

x = 5,000

The lot costs $5000.

The cost of the lot is determined by setting up an equation using the information given in which the house costs seven times as much as the lot and they total $40,000. This equation, when solved, shows the cost of the lot as $5,000.

To solve this problem, we need to set up an equation using the information given. Let's use x to represent the cost of the lot. According to the question, the house costs seven times as much as the lot, so the house costs 7x. Together, they cost $40,000. So we have the equation:

x + 7x = $40,000

We simplify this to 8x = $40,000. Then, when we solve for x by dividing both sides of the equation by 8, we find that x, or the cost of the lot, is $5,000.

Answer:

x=0

y=-3

6x-5y=15

x=y+3

Replace x with y+3

6(y+3)-5y=15

Distribute

6y+18-5y=15

y= -3

x=0

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

We can substitute equation 2 into equation 1 to find the value of x, and then use that value to find the value of y.

Substituting equation 2 into equation 1:

[tex]\[6(y + 3) - 5y = 15\]\[6y + 18 - 5y = 15\]\[y + 18 = 15\]\[y = 15 - 18\]\[y = -3\]\\[/tex]

Now that we have found y, we can substitute this value back into equation 2 to find x:

[tex]\[x = (-3) + 3\]\[x = 0\][/tex]

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

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.

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: 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:

[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 cost of 2 erasers will be - $1.2

We have pencils and erasers.

We have to determine the cost of 2 erasers.

The equation modelling is a method of forming

According to the question -

Assume that the cost of a single pencil is x and that of eraser is y. Then -

5x + 4y = 7.65   ---[1]

and

4x + 5y = 7.20   ---- [2]

4x = 7.20 - 5y

Consider Equation - [1] :

5x + 4y = 7.65

4x + x + 4y = 7.65

7.20 - 5y + x + 4y = 7.65

x - y = 0.45

x = 0.45 + y    ----- [3]

Substituting x from equation 3 in [1] -

5[0.45 + y] + 4y = 7.65

2.25 + 5y + 4y = 7.65

9y = 5.4

y = 0.6

Therefore -

x = 0.45 + 0.6 = 1.05

Therefore, the cost of 2 erasers will be -  2 x 0.6 = $1.2

Hence, the cost of 2 erasers will be - $1.2
