A.
68.4 square units
B.
75.3 square units
C.
84.5 square units
D.
136.7 square units
Answers
Answer:
Option A. 68.4 square units.
Step-by-step explanation:
Since sides ED = EF = 13 units
So the given triangle is an isosceles triangle and in an isosceles triangle EFD, perpendicular drawn from E to DF, will be perpendicular bisector of DF.
Moreover, to this perpendicular bisector to DF will be the height of the triangle.
Now Area of a triangle of [tex]\frac{1}{2}[/tex] × base × height.
Sin 63 = [tex]\frac{Height}{Hypotenuse}[/tex] = [tex]\frac{h}{13}[/tex]
h = 13 sin 63 = 13 ( 0.891) = 11.583 units
Cos 63 = [tex]\frac{Base}{Hypotenuse}[/tex] = [tex]\frac{Base}{13}[/tex]
Base = 13 cos 63 = 13 × (0.454)
= 5.90 units
Since DF = 2 × base = 2 × 5.90
= 11.80 units
Now area of EDF = [tex]\frac{1}{2}[/tex] × 11.80 × 11.583
= 68.86 ≈ 68.40 square units.
Option A. 68.4 square units.

What is the first step to be done when solving this equation: 3(x-2+3) + 5 = 25
Answers
3(x - 2 + 3) + 5 = 25
Ok, so the first step is to distribute the parentheses:
3(x - 2 + 3) = 3x - 6 + 9 <<< answer
Next step:
plug it in the equation
3x - 6 + 9 + 5 = 25
Simplify,
3x + 8 = 25
Then,
subtract 8 from both sides
3x = 25 - 8
so, 3x = 17
Divide both sides by 3
x = 17/3

Write a real word problem that involves classifying a quadrilateral
Answers
Maybe this helps or at least take ideas from this for me it wasn’t good but at least its something
Alice needs to classify her garden quadrilateral to determine if it is suitable for a specific species of flowers. She finds the sides equal in length and consecutive angles supplementary, which leads her to conclude the garden plot is a rhombus, meeting the criteria for her flowers.
Alice designs a garden plot in the shape of a quadrilateral. She knows that for a certain species of flower to grow optimally, her garden must have a specific shape: it needs to be a parallelogram with equal sides but not necessarily equal angles. In order to classify the quadrilateral of her garden, she begins by measuring the sides and finds that they are all of equal length. Then she measures the angles and finds that consecutive angles are supplementary, which means their measures add up to 180 degrees.
To determine if the quadrilateral meets the criteria for the species of flowers, she must classify her garden plot based on her measurements. Is Alice's garden a rectangle, a square, a rhombus, or a parallelogram with unequal angles?
Since the sides of the quadrilateral are all equal and the consecutive angles are supplementary, Alice can conclude that her garden plot is a rhombus, which is a type of parallelogram with all sides equal in length and opposite angles equal. Thus, it fulfills the requirements for her special species of flowers.

The angles of right isosceles triangle are such that there is the right angle, 90 degrees, and there are two identical angles that add up to 90.
17.
It is impossible to have an obtuse equilateral because and obtuse triangle has an angle that is more than 90 but less than 190. The equilateral triangle has all the angles equaling the same; 60 degrees. 60 degrees isn't obtuse so it is impossible to have an obtuse equilateral triangle.

For this case we must write the numbers from highest to lowest.
We observe that the numbers are written in exponential notation.
Therefore, by rewriting we have:
Brand A:

Brand B:
[tex] 3.84 * 10 ^ 7 = 38,400,000

Let A and B be two events in a sample space S such that
P(A)=.6 P(B)=.5 and P(A intersect B) =.2 Find
A) P(A|B)
B) P(B|A)
Please explain how to do this! Thank you
Answers
A) P(A intersect B) = P(A|B)*P(B)
Replacing the known vallues:
0.2=P(A|B)*0.5
Solving for P(A|B):
0.2/0.5=P(A|B)*0.5/0.5
0.4=P(A|B)
P(A|B)=0.4
B) P(B intersect A) = P(B|A)*P(A)
Replacing the known vallues:
0.2=P(B|A)*0.6
Solving for P(B|A):
0.2/0.6=P(B|A)*0.6/0.6
2/6=P(B|A)
1/3=P(B|A)
P(B|A)=1/3
The population of a town is 6500 and is increasing at a rate of 4% per year.at this rate, approximately what will the towns population be in 4 years
Answers
End of 1st year = 1.04 x 6500 = 6760
End of 2nd year = 1.04 x 6760 = 7030
End of 3rd year = 1.04 x 7030 = 7312
End of 4th year = 1.04 x 7312 = 7604
To find the town's population in 4 years with an initial population of 6500 and a 4% annual growth rate, we use the exponential growth formula, resulting in an estimated population of approximately 7609.
The population of a town is 6500 and is increasing at a rate of 4% per year. To calculate the town's population in 4 years, we will use the formula for exponential growth:
P(t) = P0(1 + r)^t
Where:
P(t) is the future population
P0 is the initial population
r is the growth rate (as a decimal)
t is the number of years
Step-by-step calculation:
Convert the growth rate from a percentage to a decimal: r = 4% = 0.04
Use the formula with t = 4 years, P0 = 6500, and r = 0.04:
P(4) = 6500(1 + 0.04)⁴
Calculate P(4) = 6500 * 1.04⁴
Approximate the future population after 4 years.
By performing the calculation, the town's population in 4 years will be approximately 7609.

Which of the following is the solution to the equation 25^(z + 2) = 125?
Answers
Answer:
z = -0.5
Step-by-step explanation:
Using exponent rule:
[tex]x^a = x^b[/tex] then a = b
Given the equation:
[tex]25^{z+2} = 125[/tex]
We can write 25 and 125 as:
[tex]25 = 5 \cdot 5 = 5^2[/tex]
[tex]125 = 5 \cdot 5 \cdot 5 = 5^3[/tex]
then;
[tex]5^{2(z+2)}= 5^3[/tex]
Apply the rule:
[tex]2(z+2) = 3[/tex]
using distributive property [tex]a \cdot (b+c) = a\cdot b+ a\cdot c[/tex]
[tex]2z+4 = 3[/tex]
Subtract 4 from both sides we have;
[tex]2z = -1[/tex]
Divide both sides by 2 we have;
z = -0.5
Therefore, the solution for the given equation is, z = -0.5

Answer for number 5?
Answers
P = 2L + 2W
Where,
L: side
W: width
On the other hand we have that the ratio is:
L / W = 5/3
Clearing L we have:
L = (5/3) * (W)
Substituting in the expression of the perimeter:
P = 2 ((5/3) * (W)) + 2W
Rewriting:
P = (16/3) W
The perimeter is 192:
192 = (16/3) W
We cleared W:
W = (3/16) * (192)
W = 36
Finally we substitute W in the expression for L:
L = (5/3) * (W)
L = (5/3) * (36)
L = 60
Answer:
The width and length are:
W = 36 yards
L = 60 yards
