Answer:
? = 64°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
The third angle in the triangle on the right is
third = 180° - (84 + 36)° = 180° - 120° = 60°
Thus the third angle in the triangle on the left is
third = 90° - 60° = 30° , then
? = 180° - (86 + 30)° = 180° - 116° = 64°

A statistical question is a question that can be answered by collecting data that vary. For example, “How old am I?” is not a statistical question, but “How old are the students in my school?” is a statistical question.
Now use the expression found in Part C for the distance between your eyes and the object at point O, and find the ratio of the apparent distance to the real distance, d/D. Remember that the apparent distance is the distance calculated by your eyes using the angle θa instead of the angle θw. Since we are dealing with small angles, you may use the approximation sin(x)≈x and asin(x)≈x.

Hello your question is incomplete attached below is the missing part of the question
answer : ( d / D ) = [tex]n_{a}[/tex]
[tex]n_{w}[/tex]
Step-by-step explanation:
Given data:
Apparent distance = distance calculated using angle ∅a
also applying the approximation ; sin(x) ≈ x and asin(x) ≈ x
Find the ratio of apparent distance to real distance (d / D )
Using the given data in the question the ratio of apparent distance to real distance ( d / D ) = [tex]n_{a}[/tex]
[tex]n_{w}[/tex]
where [tex]n_{a}[/tex] = index of refraction ( air )
[tex]n_{w}[/tex] = index of refraction ( water )

Kevin, Luke and mat share £200 in the ratio 1:4:3 how much more money does Luke receive than Kevin
Answers
Answer:
£75
Step-by-step explanation:
sum the parts of the ratio, 1 + 4 + 3 = 8 parts
Divide the amount by 8 to find the value of one part of the ratio
£200 ÷ 8 = £25 ← value of 1 part of the ratio, then
4 parts = 4 × £25 = £100 ← Luke's share
Thus
£100 - £25 = £75
Luke receives £75 more than Kevin

sin 47 = KX/8.9
KX = 6.509
angle LKX = 90-47-28 = 15 degrees

Paul built a triangular garden in his backyard, which is enclosed by a rectangular fence. How much of the backyard is not covered by the garden
Answers
Answer: 476m²
Step-by-step explanation:
Find the area of the triangle and then subtract it from the area of the rectangle.
Area of triangle = 1/2 * base * height
= 1/2 * 8 * 6
= 24m²
Area of rectangle:
= Length * Width
= 25 * 20
= 500m²
Area not covered by garden:
= 500 - 24
= 476m²

0 Example: Loan payments of $400 due 95 days ago and $700 due today
are to be repaid by a payment of $600 thirty days from today and the
balance in 125 days. If money is worth 6% and the agreed focal date is
125 days from today, what is the size of the final payment?
Answers
Answer:
[tex]X=\$519.48[/tex]
Step-by-step explanation:
From the question we are told that
Loan 1 [tex]X_1=\$400[/tex]
Loan 1 due [tex]t_1=95days[/tex]
Loan 2 [tex]X_2=\$700[/tex]
Loan 2 due[tex]t_2=0days[/tex]
Payment [tex]Y=\$600[/tex]
Worth of money [tex]w=6\%[/tex]
Payment due [tex]t=30days[/tex]
Focal date [tex]t_f=125days[/tex]
Generally [tex]\$400[/tex] was due 95days ago
Therefore
[tex]125+90=220days[/tex](total days to consider)
Therefore
[tex]300+400 =700[/tex] is due today
125days left
Given
600 due in 30days
[tex]125-30=95days[/tex]
Generally the Final payment is mathematically given by
[tex]400(1+ 0.06*\frac{220}{365} ) + 700(1+0.06*\frac{125}{365} )=600(1+0.06*\frac{95}{365} )+X[/tex]
[tex]X=1128.9692 - 609.3698[/tex]
Therefore the

One of the sides of a parallelogram has the length of 5 in. can the lengths of the diagonals be: 4 in and 6 in?
PLEASE PROVIDE AN EXPLANATION
Answers
Answer:
Yes, the diagonals could be 6 and 7 in. In a parallelogram, only the opposite sides of the parallelogram are congruent.
Step-by-step explanation:
In a parallelogram, the diagonals bisect each other, so you can set the labeled segments equal to one another and then solve for . \displaystyle 20 - 3x = 2x - 4 \rightarrow 24 = 5x \rightarrow 4.8 = x. Then, substitute 4.8 for in each labeled segment to get a total of 11.2 for the diagonal length.

We have the expression:
[tex]7^{1/5}*49^{7/5}[/tex]
We know that 49 = 7*7
Then we can write the above relation as:
[tex]7^{1/5}*49^{7/5} = 7^{1/5}*(7^2)^{7/5}[/tex]
We can use the second relationship from the above ones and write this as:
[tex]7^{1/5}*(7^2)^{7/5} = 7^{1/5}*7^{2*7/5} = 7^{1/5}*7^{14/5}[/tex]
Now we can use the first relationship to get:
[tex]7^{1/5}*7^{14/5} = 7^{1/5 + 14/5} = 7^{15/5} = 7^3 = 343[/tex]
Then:
The first option is equivalent.
The second option is not equivalent
The third option is equivalent.
The fourth option is not equivalent.
