Answer:
42.43 feets
Step-by-step explanation:
Given :
(Height of house / shadow of house) = (height of person / shadow of person)
(height of house / 65) = (4.8 / 7.2)
Cross multiply
Height of house * 7.2 = 4.7 * 65
Height of house = 305.5 / 7.2
Height of house = 42.43 feets

Students are doing an experiment: that two fair dice are tossed, and all the outcomes are recorded.Then,an event is described as:the sum of the two up faces are recorded. Describe the random variable, X, in this event.Writethe sample space of this event. Calculatethe probability of rolling a 4, and probability of rolling a 12.
Answer:
1.The random variable X can take any value from( 2,- ----,12) in the event of the sample space.
2.The sample space S = [(1, 1), (1, 2),(2, 1), (1, 3), (2, 2),(3, 1), (1, 4),(2, 3),(3, 2),(4, 1), (1, 5),(2, 4), (3, 3),(4, 2),(5, 1),(1, 6), (2, 5),(3, 4),(4, 3),(5, 2), (6, 1), (2, 6),(3, 5), (4, 4), (5, 3), (6, 2),(3, 6), (4, 5), (5, 4), (6, 3),(4, 6) (5, 5), (6, 4),(5,6), (6,5),(6,6)]
3. The probability of getting a 4 = 1/12
4. The probability of getting a 12 = 1/36
Step-by-step explanation:
There are 36 outcomes in all and the event shows the possible numbers obtained after the sum .
The event will be E= [ 2,3,4,5,6,7,8,9,10,11,12]
The random variable X can take any value from( 2,- ----,12) in the event of the sample space.
The sample space S = [(1, 1), (1, 2),(2, 1), (1, 3), (2, 2),(3, 1), (1, 4),(2, 3),(3, 2),(4, 1), (1, 5),(2, 4), (3, 3),(4, 2),(5, 1),(1, 6), (2, 5),(3, 4),(4, 3),(5, 2), (6, 1), (2, 6),(3, 5), (4, 4), (5, 3), (6, 2),(3, 6), (4, 5), (5, 4), (6, 3),(4, 6) (5, 5), (6, 4),(5,6), (6,5),(6,6)]
that is it has all the possible outcomes of both the dice.
The probability of getting a 4= Number of fav outcome/ no of possible outcomes= 3/ 36= 1/12
The probability of getting a 12= Number of fav outcome/ no of possible outcomes=1/36
Rewrite the equation of the line 5y = -1/4x - 6 in standard form
Answer:
D
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C
Given
5y = - [tex]\frac{1}{4}[/tex] x - 6 ( multiply through by 4 to clear the fraction )
20y = - x - 24 ( add x to both sides )
x + 20y = - 24 → D

Hello Solving Equations Puzzle
Answer:
Pink Trapezium = 30 as 30 x 1 = 30
Purple Diamond = 2 as 2 x 2 = 4
Green Moon = 7.5 as it shares the line with 4 it goes 4 x 7.5 = 30
The weight of the line is dividing line just the same as multiple when we find the numbers from dividing. But work out 2 x 2 first. then use that number to divide into 30 to find 7.5.
When we show the values see below. We have 30 also for the second line so both lines are equivalent
Step-by-step explanation:
I would multiply as addition is just too easy.
Pink Trapezium is 1 x 30 = 30 = 30/1 = 30 value
Purple diamond = 2 x 2 = 4 = 4/2 = 2 value
Green Moon is 30/4 = 7.5 value

Answer:
A. 82.9 yds
Step-by-step explanation:
The missing leg of the right triangle can be found from ...
w²+ l² = d²
w² + 125² = 150²
w² = 150² -125² = 22500 -15625 = 6875
w = √6875 ≈ 82.9
The width of the field is about 82.9 yards.

use the graph f(x)=-x²+8x+20 to determine the values of: p for which -x²+8x+p=0 will have equal roots
According to the discriminant of the quadratic equation, it will have equal roots for p = -16.
What is the discriminant of a quadratic equation and how does it influence the solutions?A quadratic equation is modeled by:
[tex]y = ax^2 + bx + c[/tex]
The discriminant is:
[tex]\Delta = b^2 - 4ac[/tex]
The solutions are as follows:
If [tex]\mathbf{\Delta > 0}[/tex], and it is a perfect square, it has 2 rational solutions.If [tex]\mathbf{\Delta > 0}[/tex], and it is not a perfect square, it has 2 irrational solutions.If [tex]\mathbf{\Delta = 0}[/tex], it has equal roots.If [tex]\mathbf{\Delta < 0}[/tex], it has 2 complex solutions.In this problem, the equation is:
[tex]f(x) = -x^2 + 8x + p[/tex]
Hence the coefficients are a = -1, b = 8, c = p.
It has equal roots if [tex]\Delta = 0[/tex], hence:
[tex]b^2 - 4ac = 0[/tex]
[tex]8^2 + 4p = 0[/tex]
[tex]4p = -64[/tex]
[tex]p = -16[/tex]

The volume of a pyramid with a square base is 400 cm³.
What is a pyramid?A pyramid is a structure where outer surfaces are triangular and converge to a point at the top.
The volume of a pyramid with a square base is given as:
Volume = 1/3 x base area x height
We have,
The volume of a pyramid with a square base is given as:
Volume = 1/3 x base area x height
Now,
Height = 12 cm
Base area = 10² = 100 cm²
Now,
Volume.
= 1/3 x 100 x 12
= 400 cm³
Thus,

x is inversely proportional to the square root of y
When x = 12, y = 9
Find the value of x when y= 81
Answer: 4
Step-by-step explanation:
The formula for inverse proportion is x = k / y. Since x is inversely proportional to the square root of y. This will be:
x = k / ✓y
When x = 12, y = 9
We have to calculate the constant of proportionality, k which will be:
12 = k / ✓9
12 = k / 3
k = 12 × 3
k = 36
To find the value of x when y = 81 will be:
x = k / ✓y
x = 36 / ✓81
x = 36 / 9
x = 4
Therefore, x = 4 when y = 81.
