Answer:
what is x
Step-by-step explanation:
way to solve for this is to set up the base and height. then you can use the area (if given) to divide the area from the side you know to get your answer.
Answer:
**If the interest is by year then this should work
The interest is $15600 and the amount is $80600.
Step-by-step explanation:
Problem
You deposit $65000 into a bank account paying 6% simple interest per year. You left the money in for 4 years. Find the interest earned and the amount at the end of those 4 years?
Result:
The interest is $15600 and the amount is $80600.
Switch the variable x and y with each other. Then the correct option is B.
<h3>What is inverse of a function?</h3>
Let the function will be
f: X → Y
Then the inverse function will be
f⁻¹: Y → X
The function is given below.
f(x) = 3x – 10
Then the inverse function of the f(x) will be
Put y in place of f(x).
x = 3y – 10
3y = x + 10
y = (x + 10) / 3
Switch the variable x and y with each other.
Then the correct option is B.

Answer:
2
Step-by-step explanation:
Total number of cards = 65
<em>she makes the same number of cards everyday for 7 days</em>
Number of days = 7
Cards per day = 65 / 7 = The result is 9 with a remainder of 2.
This means, she makes 9 cards per day for 7 days. Then on the last day she is left with 2 cards to make.
Answer:
The Height of the tower is 188.67 ft
Step-by-step explanation:
Given as :
The angle of elevation to tower = 15°
The distance travel closer to tower the elevation changes to 42° = 497 ft
Now, Let the of height of tower = h ft
The distance between 42° and foot of tower = x ft
So, The distance between 15° and foot of tower = ( x + 497 ) ft
So, From figure :
<u>In Δ ABC </u>
Tan 42° = 
Or , Tan 42° = 
Or, 0.900 = 
∴ h = 0.900 x
Again :
<u>In Δ ABD </u>
Tan 15° =
Or , Tan 15° = 
Or, 0.267 = 
Or, h = ( x + 497 ) × 0.267
So, from above two eq :
0.900 x = ( x + 497 ) × 0.267
Or, 0.900 x - 0.267 x = 497 × 0.267
So, 0.633 x = 132.699
∴ x = 
Or, x = 209.63 ft
So, The height of tower = h = 0.900 × 209.63
Or, h = 188.67 ft
Hence The Height of the tower is 188.67 ft Answer
