John bought 8 goats at 1040000.He sold these goats and made a profit of 15% on each goat.How much did he sell each goat?
Answer:
149500
Step-by-step explanation:
since there's 8 goats, each goat would be 1040000/8, which is 130000 per goat.
marketing at a 15% increase means the new percentage would be 115%, which could be represented by 1.15.
130000 * 1.15 = 149500 / goat
Find the Average
100-90-80-89-75-0
Explain how u got ur answer
Someone help I will give brainlist for whoever explains it
Answer:
72.3
Step-by-step explanation:
So, to find the average you need to add all the numbers together and divide it by the amount of numbers there are, if that makes sense.
so in your question: 100 + 90 + 80 + 89 + 75 + 0= 434
and there are 6 numbers that you had to add together, so you divide 434 by 6, which is 72.3 so that's the answer! It's quite easy once you understand how to do it :)

plz hurry!! A person standing close to the edge on top of a 108-foot building throws a ball vertically upward. The quadratic function h ( t ) = − 16 t 2 + 132 t + 108 h ( t ) = - 16 t 2 + 132 t + 108 models the ball's height above the ground, h ( t ) h ( t ) , in feet, t t seconds after it was thrown. a) What is the maximum height of the ball?
Answer:
The maximum height of the ball is 380.25 feet in the air.
Step-by-step explanation:
The quadratic function:
[tex]h(t)=-16t^2+132t+108[/tex]
Models the ball's height h(t), in feet, above the ground t seconds after it was thrown.
We want to determine the maximum height of the ball.
Note that this is a quadratic function. Therefore, the maximum or minimum value will always occur at its vertex point.
Since our leading coefficient is leading, we have a maximum point. So to find the maximum height, we will find the vertex. The vertex of a quadratic equation is given by:
[tex]\displaystyle \left(-\frac{b}{2a},f\left(\frac{b}{2a}\right)\right)[/tex]
In this case, a = -16, b = 132, and c = 108. Find the t-coordinate of the vertex:
[tex]\displaystyle t=-\frac{132}{2(-16)}=-\frac{132}{-32}=\frac{33}{8}=4.125[/tex]
So, the maximum height occurs after 4.125 seconds of the ball being thrown.
To find the maximum height, substitute this value back into the equation. Thus:
[tex]h(4.125)=-16(4.125)^2+132(4.125)+108=380.25\text{ feet}[/tex]
The maximum height of the ball is 380.25 feet in the air.

ОА
B
Ос
Answer:
The Right option is D
Step-by-step explanation:
From the picture below,
For A,
15y = 6x
Where we divide both side of the equation by 3
15y/3 = 6x/3
5y = 2x
For B,
y = 2/5(x)
y×5 = 2x
5y = 2x.
For C,
10y = 4x
Divide both side of the equation by 2
10y/2 = 4x/2
5y = 2x.
For D,
5xy = 2. It can not be simplified futher.
Therefore,
From the above simplification, We can see that,
Equation A = Equation B = Equation C.
Equation D is the only Equation that does not belong to the other three.
Hence the right option is D

A box contains 5 red, 4 white and 6 blue balls. If three balls are drawn at random without replacement, determine the probability that none of the balls selected is red.
Answer:
The probability that none of the balls selected is red ²⁴/₉₁
Step-by-step explanation:
Given;
number of red balls, R = 5
number of white balls, W = 4
number of blue balls, B = 6
Total number of balls, = 5 + 4 + 6 = 15
Probability of selecting 3 none red balls = P(WWW) or P(BBB) or P(WWB) or P(WBW) or P(BWW) or P(BBW) or P(BWB) or P(WBB)
[tex]P = (\frac{4}{15} \times \frac{3}{14} \times \frac{2}{13} ) + (\frac{6}{15} \times \frac{5}{14} \times \frac{4}{13} ) + (\frac{4}{15} \times \frac{3}{14} \times \frac{6}{13} ) + (\frac{4}{15} \times \frac{6}{14} \times \frac{3}{13} ) + \\\\(\frac{6}{15} \times \frac{4}{14} \times \frac{3}{13} ) + (\frac{6}{15} \times \frac{5}{14} \times \frac{4}{13} ) + (\frac{6}{15} \times \frac{4}{14} \times \frac{5}{13} ) + (\frac{4}{15} \times \frac{6}{14} \times \frac{5}{13} )[/tex]
[tex]P = \frac{24}{2730} + \frac{120}{2730} + \frac{72}{2730} +\frac{72}{2730} + \frac{72}{2730} + \frac{120}{2730} + \frac{120}{2730} + \frac{120}{2730} \\\\P = \frac{720}{2730} \\\\P = \frac{24}{91} \\\\[/tex]

Belinda's shoe is 12.45 centimeters long. Felix's shoe is 2.8 centimeters longer than Belinda's shoe. In centimeters, what is the combined length of their two shoes?
Answer:
27.7 cm
Step-by-step explanation:
(12,45cm + 2.8cm)=(belinda's shoe+felix added cm)= felix's shoe
12,45cm= belinda shoe
combined lenght = 12,45+ 15,25=27.7 cm
The combined length of the Belinda's shoe which is 12.45 centimeters long and Felix's shoe is 27.7 centimeters.
How to measure the length?Length measurement is the measurement of the size of a object. The units of length measurement are meter, feet, yards etc.
In the metric system of length measurement the units are meter, kilometer, centimeter etc.
Centimeter-This unit is used when the size of a small object has to measure, such as match box, books. There are total 100 centimeters in one meter.Meter-This is the basic unit of length measurement of size. The size of room, length of wall measured in centimeter.Belinda's shoe is 12.45 centimeters long. Felix's shoe is 2.8 centimeters longer than Belinda's shoe. Let suppose the length of Felix's shoe is x meters. Thus,
[tex]x=12.45+2.8\\x=15.25\rm\; cm[/tex]
In centimeters, the combined length of their two shoes is,
[tex]l=15.25+12.45\\l=27.7\rm\; cm[/tex]
Thus, the combined length of the Belinda's shoe which is 12.45 centimeters long and Felix's shoe is 27.7 centimeters.

9. The height of a ball thrown into the air is a quadratic function
of time. The ball is thrown from a height of 6 ft above the
ground. After 1 second, the ball reaches its maximum height of
22 ft above the ground. Write the equation of the function in
vertex form.
Answer:f(x)=-16(x-1)^2+22
Step-by-step explanation:
The equation for the trajectory of ball in the air is h(t) = -16t² + 32t + 6.
What is differentiation?The differentiation of a function is defined as rate of change of its value at a point. It can be written as f'(x) = lim h --> 0 (f(x + h) - f(x)) /(x + h - x).
It can also be said as the slope of the tangent for the function at a given point.
Given that,
The maximum height reached by the ball after 1 sec is 22 ft above ground.
And, the height at which it is thrown is 6 ft above the ground.
Which implies at 0 sec the height is 6 ft.
The quadratic function for the height can be written as,
h(t) = at² + bt + c
Substitute t = 0 to gat,
f(0) = a × 0² + b × 0 + c
=> c = 6
Now, for maximum height,
h'(t) = 0
=> 2at + b = 0
At maximum height t = 1
Then, the above expression becomes,
2a × 1 + b = 0
=> a = -b/2
Substitute t = 1 in h(t) = at² + bt + c to get,
22 = a + b + c
=> 22 = -b/2 + b + 6
=> b/2 = 16
=> b = 32
Then, a = -b/2
= -32/2
=-16
Thus substituting the corresponding values the equation can be written as h(t) = -16t² + 32t + 6.
Hence, the required equation for the path of the ball in the air is h(t) = -16t² + 32t + 6.

Factor `y=2x^2+11x+5`
Answer:
(2x + 1)(x + 5).
Step-by-step explanation:
`y=2x^2+11x+5`
2 * 5 = 10
1 * 10 = 10 and 1 + 10 = 11 so we write:
y = 2^2 + 10x + x + 5
y = 2x(x + 5) + 1(x + 5)
= (2x + 1)(x + 5).

Answer:
64 square units
Step-by-step explanation:
if you spilt up the polygon you can find the area of the square and triangle making up the square.
length * width = Area; 6 * 8 = 48 sq units for the square part
1/2 * base * height = Area; 1/2 * 4 * 8 = 16 sq units for the triangle part
then add the two areas together for the area of the entire polygon:

Find the lateral area of this cone.
Leave your answer in terms of pi.
3cm
4cm
The lateral area of the cone is 20π square centimeters.
Given that a cone with base radius of 4 cm and the height is 3 cm, we need to find the lateral area of the cone,
The lateral area of a cone can be calculated using the formula:
Lateral Area = π r l
where:
π is a mathematical constant approximately equal to 3.14159.
r is the radius of the base of the cone.
l is the slant height of the cone.
To find the slant height, we can use the Pythagorean theorem.
The slant height (l) is the hypotenuse of a right triangle formed by the height (h) and the radius (r) of the cone.
The formula is:
l = √(r² + h²)
Given that the base radius (r) is 4 cm and the height (h) is 3 cm, we can calculate the slant height (l):
l = √(4² + 3²)
= √(16 + 9)
= √(25)
= 5
Now we can substitute the values into the formula for the lateral area:
Lateral Area = π r l
= π × 4 × 5
= 20π
Therefore, the lateral area of the cone is 20π square centimeters.
