Let the triangle be ΔABC , and
∠A = ∠B = ∠C = 60° and AB = BC = CA
Given data ,
Let the triangle be represented as ABC
Now , the triangle ABC is an equilateral triangle
So , AB = BC = CA
The perimeter of the triangle is P = 27 feet
So , the base length of the triangle AB = 27/3 = 9 feet
The height of the triangle = 7.8 feet
Now , area of the triangle = ( 1/2 ) x Length x Base
Substituting the values in the equation , we get
The area of the triangle A = ( 1/2 ) x 7.8 x 9

A line passes through the point (-6, -7) and has a slope of 2. Write an equation in point-slope form for this line.
Answer: (y + 7) = 2(x + 6)
Step-by-step explanation:
A point-slope form equation is given as (y - y1) = m(x - x1) where (x1, y1) is a given coordinate point, m is the slope, and x and y are variables. We will substitute the given information into this base equation.
(y - y1) = m(x - x1)
(y - - 7) = 2(x - - 6)
(y + 7) = 2(x + 6)
a quantity with an initial value of 510 grows exponentially at a rate such that the quantity doubles every 8 decades. what is the value of the quantity after 7 years, to the nearest hundredth?
After five decades, the amount is worth to the nearest hundredth is 607.54
Any decimal number is rounded to the nearest hundredth by the term "to the nearest hundredth." A hundredth is 1/100 or 0.01 in decimal form. For instance, 2.17 is the result of rounding 2.167 to the nearest tenth.
Look at the next place value to the right in order to round a number to the closest hundredth (the thousandths this time). The same applies: Simply eliminate all the digits to the right if the number is 4 or fewer. Add 1 to the digit in the hundredths place if the number is five or above, and then eliminate all the digits to the right.
The equation below can be used to describe this amount at intervals of 2t decades. where r is the rate of increase and Q(0) is the initial quantity. A 510-valued quantity increases exponentially at a rate of 7% every 20 years. After five decades, the amount is worth 607.54

if we spin the two spinners at the same time, what is the probability that both spinners will yield odd numbers?]
There is a 1/2 probability that both spinners will produce an odd number.
What is probability?The probability is equal to the variety of possible outcomes.
The total number of outcomes that could occur.
For instance, there is only one way to receive a head and there are a total of two possible outcomes, hence the probability of flipping a coin and getting heads is 1 in 2. (a head or tail). P(heads) = 12 is what we write.
So, assume that:
Both the spinners have 1 positive number and 1 odd number.
Probability formula:
P(E) = Favourable events/Total events
Now, calculate as follows:
P(E) = Favourable events/Total events
P(E) = 2/4
P(E) = 1/2
Therefore, there is a 1/2 probability that both spinners will produce an odd number.

In triangle GHJ , m angle H=110 , m angle J=40 , and I is the point on overline GJ that makes overline HI bisect GHJ. What is the longest side of triangle HIJ ?
Answer:
In triangle GHJ, if m angle H = 110 and m angle J = 40, then m angle G = 180 - (110 + 40) = 30. Since angle I is the angle bisector of angle GHJ, the ratio of the length of side HI to the length of side HJ is equal to the ratio of the length of side GI to the length of side GJ.
Since the longest side of a triangle is opposite to the largest angle, the longest side of triangle HIJ is GJ.

Answer:
A quadrilateral is a parallelogram if and only if opposite angles are equal.
So, to make the quadrilateral a parallelogram, we can set the following equalities:
(4x + 13) deg = (5x - 12) deg
(4y + 7) deg = (3x - 8) deg
Solving the first equation,
4x + 13 = 5x - 12
x = -5
Solving the second equation,
4y + 7 = 3(-5) - 8
4y + 7 = -17
4y = -24
y = -6
So, the values of x and y that make the quadrilateral a parallelogram are x = -5 and y = -6

The melting point of ice is 0 degree celsius. during a chemistry experiment, jill observed ice melting within 2 degrees celsius of this measurement. find the range of temperature that jill observed. define a variable, write an inequality, and solve.
The typical definition of the melting point is the temperature at which a substance transforms from a solid to a liquid.
What do you mean by melting point?
melting point, temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached.
The melting point of a liquid is the temperature at which the liquid transforms from a solid to a liquid under atmospheric pressure. This is the location where the liquid and solid phases are equally present. The substance's melting point varies with pressure as well and is reported at standard pressure.
As the melting point is 0 °C.
So, it melts at 2 C. It can melt from 0 °C – 2 °C to 0 °C + 2 °C.

Step-by-step explanation:
(a)
x - 9y = 10 ( add 9y to both sides )
x = 9y + 10 → (1)
3y² = 4x + 7 → (2)
substitute x = 9y + 10 into (2)
3y² = 4(9y + 10) + 7
3y² = 36y + 40 + 7
3y² = 36y + 47 ( subtract 36y + 47 from both sides )
3y² - 36y - 47 = 0 ← as required
(b)
solving using the method of completing the square
add 47 to both sides
3y² - 36y = 47 ← factor out 3 from each term in the left side
3(y² - 12y) = 47
to complete the square on the left
add/subtract ( half the coefficient of the y- term)² to y² - 12y
3(y² + 2(- 6)y + 36 - 36) = 47
3(y - 6)² - 3(36) = 47
3(y - 6)² - 108 = 47 ( add 108 to both sides )
3(y - 6)² = 155 ( divide both sides by 3 )
(y - 6)² = [tex]\frac{155}{3}[/tex] ( take square root of both sides )
y - 6 = ± [tex]\sqrt{\frac{155}{3} }[/tex] ≈ ± 7.2 ( to 1 decimal place )
add 6 to both sides
y = 6 ± 7.2
then
y = 6 - 7.2 = - 1.2
y = 6 + 7.2 = 13.2
substitute these values into ( 1) for corresponding values of x
x = - 1.2 : x = 9(- 1.2) + 10 = - 10.8 + 10 = - 0.8 ⇒ (- 1.2, - 0.8 )
x = 13.2 : x = 9(13.2) + 10 = 118.8 + 10 = 128.8 ⇒ (13.2, 128.8 )
Answer:
(x, y) ≈ (-0.7, -1.2) or (128.7, 13.2)
Step-by-step explanation:
You want the solution to the simultaneous equations ...
x -9y = 103y² = 4x +7a) QuadraticSolving the first equation for x, we can substitute into the second equation to get a quadratic in y.
x = 9y +10 . . . . . . . add 9y to the first equation
3y² = 4(9y +10) +7 . . . . . substitute for x
3y² = 36y +47 . . . . . . . eliminate parentheses
3y² -36y -47 = 0 . . . . subtract the right-side expression
b) SolutionsThe equation can be written in vertex form as ...
3y² -36y = 47
3(y² -12y +36) = 47 +3(36)
3(y -6)² = 155
y -6 = ±√(155/3)
y = 6 ± (√465)/3 ≈ -1.19, 13.19
x = 9y +10 ≈ -0.69, 128.69
The approximate solutions are ...
(x, y) ≈ (-0.7, -1.2), (128.7, 13.2)

a movie theatre models the revenue from ticket sales in one day as a function of the ticket price, p. here are two expressions defining the same revenue function. p ( 120p - 4p ) and 120p - 4p 2 according to this model, how high would the ticket price have to be for the theater to make $0 in revenue? explain your reasoning. what equation can you write to find out what ticket price(s) would allow the theater to make $600 in revenue?
The ticket prices that would allow the theater to make $600 in revenue are $120 and $13.4.
In order for the theater to make $0 in revenue, the ticket price would have to be $4. This can be determined by setting the revenue functions equal to 0 and solving for p.
For p (120p - 4p) = 0
120p - 4p = 0
4p = 120
p = $30
For 120p - 4p2 = 0
120p - 4p2 = 0
4p2 = 120p
p2 = 30p
p = $4
To find the ticket prices that would allow the theater to make $600 in revenue, we can set the revenue functions equal to 600 and solve for p.
For p (120p - 4p) = 600
120p - 4p = 600
4p = 120 + 600
p = $120
For 120p - 4p2 = 600
120p - 4p2 = 600
4p2 = 120 + 600
p2 = 30 + 150

An acute angle is one that is less than 90 degrees in length. This is a smaller angle than the right angle (which is equal to 90 degrees).
Given that the measure of the angles of a triangle are x, x+10, and x+20.
The sum of the interior angles of a triangle is 180°.
According to the question,
x+x+10+x+20 = 180°
3x + 30 = 180°
3x = 150°
Divide both sides by 3:
x = 50°.
Putting x = 50° in x, x+10, and x+20.
x =50° , x+10 = 60°, and x+20 =70°.
All angles of the triangle is 90°. Thus the triangle is an acute angle triangle.

12 tons of gravel has been used for the driveway.
Weight of first load = 7 tons
Weight of second load = 8000 pounds
There are 2000 pounds (lb) in one US customary ton (t). Both tons and pounds are measurements of mass/weight in the US customary and imperial systems of measurement. However, the definitions of the ton vary in both systems. For example, there are 2240 pounds in an imperial ton, and 2204.6226 pounds in a metric ton.
The US ton is mostly used in the United States and Canada. The imperial ton was mostly used in the UK, and still is to a degree, but since the UK began the process of metrication, the metric ton is also used in the UK.
Convert pounds to tons:
1 pound = 0.0005 ton
8000 pounds = 4 ton
Then,
Weight of second load = 4 ton
Total weight of the gravel, in tons = Weight of first load + Weight of second load
= 8 tons + 4 tons

[tex](\stackrel{x_1}{-4}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{0}~,~\stackrel{y_2}{-1}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{\textit{\large rise}} {\stackrel{y_2}{-1}-\stackrel{y1}{4}}}{\underset{\textit{\large run}} {\underset{x_2}{0}-\underset{x_1}{(-4)}}} \implies \cfrac{-5}{0 +4} \implies \cfrac{ -5 }{ 4 } \implies - \cfrac{5 }{ 4 } \\\\[-0.35em] ~\dotfill[/tex]
[tex]\begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}\qquad \implies \qquad \begin{array}{llll} y=-\cfrac{5}{4}(~~x-(-1)~~) \\\\ {\Large \begin{array}{llll} y=-\cfrac{5}{4}(x+1) \end{array}} \end{array}[/tex]
if you used the same experimental design, but instead used an endotherm, what results would you expect? explain how you came to this conclusion.
if you used the same experimental design, but instead used an endotherm, you would expect to see a difference in the organism's ability to regulate its body temperature
If the same experimental design was used but with an endotherm (an organism that generates heat internally) instead of an ectotherm (an organism that relies on external sources of heat), I would expect to see a difference in the organism's ability to regulate its body temperature. Endotherms have a higher metabolic rate and are able to generate heat internally, whereas ectotherms rely on external sources of heat to regulate their body temperature. This means that endotherms would be less affected by changes in external temperature and would be able to maintain a more stable body temperature. Additionally, endotherms would likely have a higher tolerance for cold temperatures. I came to this conclusion because endotherms have internal heat regulation mechanisms that allow them to maintain a stable body temperature, whereas ectotherms do not.

you buy a package of 122 smarties and 19 of them are red. what is a 95% confidence interval for the true proportion of red smarties?
Answer:
1.96
Step-by-step explanation:
In a movie theater, the number of seats in a row is 8 greater than the number of rows. How many rows are in the movie theater if the total number of seats in the theater is 884
There are 26 rows and 34 seats per row in the movie theater.
What is an equation?An equation is an expression composed of variables and numbers linked together by mathematical operations.
Let x represent the number of seats per row and y represent the number of rows.
The number of seats in a row is 8 greater than the number of rows, hence:
x = y + 8 (1)
The total number of seats in the theater is 884, hence:
xy = 884
but x = y + 8. Substituting:
(y + 8)(y) = 884
y² + 8y - 884 = 0
y = 26
x = y + 8 = 26 + 8 = 34
There are 26 rows
