10 = hypothenuse
Sohcahtoa (cah)
Cosine uses both adjacent and hypothenuse
x/10 = cos(37)
0.79863551 = x/10
x = 7.9763551
Solution: x = 8
The value of x is 8 units after applying the cos ratio option (D) 8 is correct.
What is a right-angle triangle?It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.
We have a right-angle triangle shown in the picture.
As we know, Pythagoras' theorem is the square of the hypotenuse in a right-angled triangle that is equal to the sum of the squares of the other two sides.
The trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.
Applying the cos ratio to find the value of x:
cos37 = x/10
x = 10cos(37)
x = 7.98 ≈ 8 units
Thus, the value of x is 8 units after applying the cos ratio option (D) 8 is correct.

A trader bought 40 shirts for Birr 220 and sold them at Birr 72 each
Find the profit percentage.
Answers
Given:
Cost price of 40 shirts = Birr 220
Selling price of each shirt = Birr 72
To find:
The profit percentage.
Solution:
We have,
Cost price (CP) of 40 shirts = Birr 220
Selling price (SP) of each shirt = Birr 72
So, the selling price (SP) of 40 shirts is:
[tex]72\times 40=2880[/tex]
We need to find the profit percentage.
[tex]\text{Profit percentage}=\dfrac{SP-CP}{CP}\times 100[/tex]
[tex]\text{Profit percentage}=\dfrac{2880-220}{220}\times 100[/tex]
[tex]\text{Profit percentage}=\dfrac{2660}{220}\times 100[/tex]
[tex]\text{Profit percentage}=1209.09\%[/tex]
Therefore, the profit percentage is 1209.09%.

Madeline invests $25,000 in an account that offers a compound interest rate
of 9.5% per year. Which of the following is the correct equation for how much
Madeline will have after 8 years?
Answers
25,000 x (0.95)*8 means the interest changes every year and the interest is calculated of the annual rate
The correct equation for how much Madeline will have after [tex]8[/tex] years will be [tex]25000(1+0.095)^8[/tex] which is in option [tex](b)[/tex].
What is compound interest ?Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest
Amount [tex]=P(1+\frac{R}{100})^t[/tex]
We have,
Principal [tex]=\$25,000[/tex]
Rate[tex]=9.5\%[/tex]
Time [tex]=8[/tex] years
Now,
Using the above mentioned formula,
Amount [tex]=P(1+\frac{R}{100})^t[/tex]
[tex]=25000(1+\frac{9.5}{100})^8[/tex]
Amount [tex]=25000(1+0.095)^8[/tex]
So, the equation for final amount is [tex]25000(1+0.095)^8[/tex].
Hence, we can say that the correct equation for how much Madeline will have after [tex]8[/tex] years will be [tex]25000(1+0.095)^8[/tex] which is in option [tex](b)[/tex] .

(133)/7 - 18
133 ÷ 7 = 19
19 - 18 = 1
Answer: y = 1
Step-by-step explanation:
Well if x is 133 then the problem is y = (133/7) -18
and 133/7 is 19
so the problem is y = 19 - 18
and 19 - 18 is 1, so
y = 1
Janice bought 3 hamburgers and 4 hotdogs for her cousins and paid $8.50. Brian bought 3 hamburgers and 6 hotdogs for his cousins and paid $10.50. How much did one hamburger cost?
A) 2.00
B) 1.50
C) 1.00
D) 0.75
Answers
Answer:
Cost of each hamburger = $1.50
Step-by-step explanation:
Given:
Cost of 3 hamburger and 4 hotdog = $8.50
Cost of 3 hamburger and 6 hotdog = $10.50
Find:
Cost of each hamburger
Computation:
Cost of each hamburger = h
Cost of each hotdog = d
So,
3h + 4d = 8.50.....EQ1
3h + 6d = 10.50.......EQ2
EQ2 - EQ1
2d = 2
d = 1
3h + 4d = 8.50
3h + 4(1) = 8.50
3h = 4.50
h = 1.50
Cost of each hamburger = $1.50

D. {2, 3, 4, 5, 6}
Answers
Answer:
I think its D
Step-by-step explanation:
It's obviously not A, because A has an x instead of y. B makes no sense because the range is 2-6. C makes no sense. D is the only logical answer.
The range of the function for this situation is 17 ≤ w ≤ 47
An equation is an expression used to show the relationship between two or more variables.
Let x represent the number of textbooks in the box
The company requires a student to order at least 2 books, hence:
x ≥ 2.
w(2) = 7.5(2) + 2 = 17
Also they do not require more than 6 books, hence:
x ≤ 6
w(6) = 7.5(6) + 2 = 47
The range of a function is the set of possible dependent variables.
Hence, the range of the function for this situation is 17 ≤ w ≤ 47
