Two parallel cables are attached to a tree. The lower cable meets the tree at a height of 8 m and extends 27 m from the base of the tree. If the triangles are similar, how tall is the tree? Round your answer to the nearest 10th of a meter.
Answer:
108
Step-by-step
you multiply 1/2 by the base by the height according to the formula
so you do 1/2 by 8m by 27
the answer will come as 108 rounded off

Answer: 5.4n to the power of 5.
Step-by-step explanation: Remove parentheses. 4n 5 +3.5n 5 −2.1×n 5
You get 5.4n to the power of 5
Answer: 5.4n^5, the 3rd option.
Step-by-step explanation:
The first step to solve this is to use the distributive property to change this equation into: 4n^5 + 3.5n^5 - 2.1n^5.
Then, you add 4n^5 + 3.5n^5 which is 7.5n^5.
The last step is to subtract 2.1n^5 from 7.5n^5 which is 5.4n^5.

Carpet costs $21.95 per square yard and the padding to put under it costs $2.55 per square yard. Felix plans to install padding and carpet in the region shown in the figure. What is the total cost of the carpet and padding needed to exactly cover the room?
Answer:
$1679.175 or $1679.18
Step-by-step explanation:
split the carpet into rectangles to make it easier to look at
one rectangle is 2 yards in height and 9 yards in width (5 yards plus 4 yards)
area of a rectangle = (w)(h), so 9 x 2 = 18 yards in area.
second triangle is 4 yards in width, and 3 yards in height.
area of a rectangle = (w)(h), so 4 x 3 = 12 yards in area.
Total area = 30 yards
30(21.95)(2.55) = $1679.175 or $1679.18
Answer: $735

153 is 0.9% of what number tell which equivalent ratios are used to find a solution
0.9% / 100% = 0.009
= 9/1000
equivalent ratio:
9/1000 = 153/x
cross multiply
9x = 153,000
x = 153,000/9
x = 17,000
153/17,000 = 0.009
Find the value of x.

Step-by-step explanation:
Write an exponential function in the form y=ab^x that goes through points (0, 3) and (4, 48).
The exponential function in the form y=abˣ that goes through points (0, 3) and (4, 48) is y=3(2ˣ).
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
In order to write the exponential function in the form y=abˣ, we need to find the value of the constants a and b, therefore, substitute the value of the two points in the general equation y=abˣ.
For the first point (0,3),
[tex]y=ab^x\\\\3=ab^0\\\\ 3 = a(1)\\\\a = 3[/tex]
As we know the value of 3 now, therefore, the function can be written as y=3bˣ, Now, substitute the value of the second point in this function to get the value of b.
[tex]y = 3b^x\\\\48 = 3b^4\\\\16= b^4\\\\\text{Taking log}\\\\\rm log_b16=4\\\\\dfrac{log\ 16}{log\ b} = 4\\\\\dfrac{log\ 16}{4} = {log\ b}\\\\\text{Taking anti log}\\\\b = 2[/tex]
Thus, the value of the a is 3 and the value of b is 2, substituting the values in the general equation of the exponential function. We will get the function as y=3(2ˣ).
Hence, the exponential function in the form y=abˣ that goes through points (0, 3) and (4, 48) is y=3(2ˣ).

Jess deposited $5,000 into an account that earns simple interest. After 9 years, Jess had earned $3,150 in interest. What was the interest rate of the account?
Answer:
The interest rate of Jess's account was 7%
Step-by-step explanation:
A = P * (1 + rt)
A = final amount
P = initial principal balance
r = annual interest rate
t = time (in years)
Replacing with the values we know:
A = P * (1 + rt)
8,150 = 5,000 * (1 + r * 9)
8,150/5,000 = 1 + 9r
1.63 = 1 + 9r
1.63 - 1 = 9r
0.63 = 9r
r = 063/9
r = 0.07 = 7%
The interest rate of Jess's account was 7%
Answer:
The interest rate of Jess's account was 7%
Step-by-step explanation:
____________________________________
A = P × (1 + rt)
A = final amount
P = initial principal balance
r = annual interest rate
t = time (in years)
___________________________________
A=8,150
P=5,000
8,150 = 5,000 × (1 + r × 9)
8,150÷5,000 = 1 + 9r
1.63 = 1 + 9r
1.63 - 1 = 9r
0.63 = 9r
r = 063÷9
r = 0.07 = 7%
