a tree cast a 25 foot shadow on a sunny day, if the angle of elevation from the tip of the shadow to the top of the top of the tree is 32 degrees, what is the heights of the tree to the nearest tenth of a foot?
Answer:
Tree height is 15.6 ft
Step-by-step explanation:
Picture a triangle with horizontal side 25 ft and angle 32 degrees on the left. Then the following is true:
x
tan 32 = 0.625 = --------------------- or x = (0.625)(25 ft) = 15.6 ft
25 ft

Given y varies inversely as x, and y = 5 when x = 9. Write the inverse function
Answer:
y = 45/x
Step-by-step explanation:
Given y varies inversely as x, then;
y = k/x
If y = 5 when x = 9
5 = k/9
k = 5*9
k = 45
Substitute into the formula above;
y = k/x
y = 45/x
Hence the required inverse function is y = 45/x
In
group of 100 persons, 72 people can speak
English and 43 can speak French. How many
can speak English Only, How many can speak
French Only and how many can speak both English and French
Step-by-step explanation:
Let A be the set of people who speak English.
B be the set of people who speak French.
A - B be the set of people who speak English and not French.
B - A be the set of people who speak French and not English.
A ∩ B be the set of people who speak both French and English.
Given
n(A) = 72 n(B) = 43 n(A ∪ B) = 100
Now, n(A ∩ B) = n(A) + n(B) - n(A ∪ B)
= 72 + 43 - 100
= 72 + 43 - 100
= 115 - 100
= 15
Therefore, Number of persons who speak both French and English
= 15
n(A) = n(A - B) + n(A ∩ B)
⇒ n(A - B) = n(A) - n(A ∩ B)
= 72 - 15
= 57
and n(B - A) = n(B) - n(A ∩ B)
= 43 - 15 = 28
Therefore, Number of people speaking English only = 57
Number of people speaking French only = 28
Let A be the set of people who speak English.
B be the set of people who speak French.
A - B be the set of people who speak English and not French.
B - A be the set of people who speak French and not English.
A ∩ B be the set of people who speak both French and English.
Given
n(A) = 72 n(B) = 43 n(A ∪ B) = 100
Now, n(A ∩ B) = n(A) + n(B) - n(A ∪ B)
= 72 + 43 - 100
= 72 + 43 - 100
= 115 - 100
= 15
Therefore, Number of persons who speak both French and English
= 15
n(A) = n(A - B) + n(A ∩ B)
⇒ n(A - B) = n(A) - n(A ∩ B)
= 72 - 15
= 57
and n(B - A) = n(B) - n(A ∩ B)
= 43 - 15 = 28

Find the area of the compound figure. Round your answer to 2 decimal places if required. (Use π = 3.14)
Hello! I’ve been stuck on this problem for a while and—though I know the answer—I’m not sure how to get to it? Please help!
Answer:
Perimeter is 3 + 3 +3 +4 +5 = 18 feet
Area = 3*3 = 9, 1/2*3*4 = 6, 9 + 6 =15 square feet
perimeter = 2.5 +2.5+ 2.5+2.5+0.5+0.5 = 11 meters
Area = 3*.5 = 1.5, 3*2=6, 6+1.5 = 7.5 square meters
perimeter = 3.14*2*3 = 18.84 +8 = 26.8 inches
Area = 6*4 = 24 + 3.14*3^2 = 28.26 = 28.26 +24 = 5
Simplify:
- 5 1/4 -( -7 1/2)
Answer:
-5 1/4-(-7 1/2 is simplified to 9/4
Step-by-step explanation:
-5 1/4 is simplified to -21/4 -(-7 1/2
-7 1/2 is simplified to -15/2 and two negatives make a positive.
so the equation now becomes
-21/4+15/2
15/2 times 2 is 30/4
-21/4+30/4 is 9/4
The answer is 9/4

[tex]2)\ B[/tex]
[tex]3)\ B[/tex]
[tex]4)\ C[/tex]
Step-by-step explanation:
1)
Let's use the Pythagorean Theorem:
[tex]X^2 + 13^2 = 21^2[/tex]
[tex]X^2 + 169 = 441[/tex]
[tex]X^2 = 272[/tex]
[tex]X= \sqrt{272} = 4\sqrt{17} = 16.5[/tex]
2)
Let's use the Pythagorean Theorem:
[tex]16^2 + 28^2 = x^2[/tex]
[tex]x^2 = 1040[/tex]
[tex]x = \sqrt{1040} = 4\sqrt{65} = 32.2[/tex]
3)
Let's use the Pythagorean Theorem:
[tex]7^2 + 24^2 = 25^2[/tex]
As this equation is correct, these three lengths could be used in a right triangle.

4x-3=2x+7 please help shdjdjsjsjsndjxj
Answer:
x=5
Step-by-step explanation:
Step 1: Subtract 2x from both sides.
4x−3−2x=2x+7−2x
2x−3=7
Step 2: Add 3 to both sides.
2x−3+3=7+3
2x=10
Step 3: Divide both sides by 2.
x=5
And theres our answer.

MMM
F
MMF
MEM
A. MFM
B. FFM
C. MFF
D. FMF
Answer:
MMM
Step-by-step explanation:
Given
See attachment for elements of the sample space (in a probability tree)
Required
Which of MMM, FFM, MFF, FMF represents more than one male?
From the question, we understand that:
[tex]M \to Male[/tex]
[tex]F \to Female[/tex]
So, for an event to represent more than 1 male, there must be an occurrence of at least 2 M (i.e 2 M or 3 M)
From the given options, only MMM has more than 1 M.
Hence, MMM represents more than one Male

Answer:
Angle 4 is ∠A
Step-by-step explanation:
Cos(A) = adjacent / hypotenuse
=> Angle 1: Cos(1) = 40 / 41, or 0.98 (so this is not ∠A)
=> Angle 2: Cos(2) = 9 / 41 or 0.22 (This isn't ∠A either)
=> Angel 3: Cos(3) = 24 / 25 or 0.96 (Not ∠A)
=> Angel 4: Cos(4) = 7 / 25 or 0.28 (This is Angle A, since Cos(A) = 0.28)
Therefore; Angle 4 is ∠A
Hope this helps!
Answer:
Can't type the Full solution
I'll solve for the triangle with angles 1 and 2
You can go for the rest.
CosA = 0.28
Taking the cos-¹(0.28) to determine its Magnitude
A=73.74°
Now
We can use sine Rule to get the values of each of the other angles in the triangle
For the first triangle
Applying sine rule
What basically happens in the rule is... Each side divided by the angle opposite it.
Look below
The angle opposite 40cm is angle '2' and the angle opposite 41cm is 90°
We have this sine rule when all three sides are given with ONE ANGLE(90° is the given angle in this case)
So
Each side over the angle opposite it
We go!!
Let's call angle "2" an alphabet. Say Q
41/sin90 = 40/SinQ
SinQ = 40sin90/41
Recall sin90=1
SinQ = 40/41
Q= Sin-¹(40/41)
Q= 77.32°
so angle 2 is 77.32°
Now apply this to get others
Angle '1' should be 12.68°
Angle "3" should be 16.26°
Angle "4" should be 73.74°
Therefore
conclusion
Angle "4" is same as A. That's the angle we looking for
Option 4 IS CORRECT!!

Neva is training for a race. This week, she bikes 5.5 times as far as she runs. Her total distance running and biking this week is 26 mi. How far does Neva run this week?
Answer:
Run = 4 miles
Biked = 22 miles
Step-by-step explanation:
Given :
Let :
Number of miles ran = x
Number of miles biked = 5.5x
Total run and bike distance = 26 miles
Thus ;
x + 5.5x = 26
6.5x = 26
x = 26/6.5
x = 4
Total miles run ; x = 4 miles
Total miles biked, 5.5x = 5.5*4 = 22 miles
