Answer:
139
Step-by-step explanation:
First, find all the faces that you must find the areas of. In this case, you need to find the areas of two triangles and three rectangles.
In this triangular prism, the base is one triangle. If the area of the base is 7.75, we can assume that that holds true for both bases, and multiply 7.75 by 2 in order to find the area of both triangles.
Now find the area of each of the three rectangles by multiplying their individual heights and bases by each other. You should get 38, 47.5, and 38 as the areas of the rectangles.
Now add all the individual area's together. (They're bolded for clarity).
Answer:
The weight of the object is 3 kg.
Step-by-step explanation:
<u>Step 1:
</u>
Let object weight be x kg.
Now, as per the available data,
3/4 kg + 3/4 (x kg) = x kg
<u>Step 2:
</u>
3/4 (1 + x) = x
1 + x = 4x/3
1 = x (4/3 - 1)
x = 1 / (1/3)
x = 3
Weight of Object is 3 kg.
<u>Step 3:
</u>
Let's check if this value satisfies the first equation.
3/4 + 3/4 x 3 = 3/4 + 9/4 = 12/4 = 3
Hence proved.
A. Write a function f(x) to represent the price after the 80% markup.
<span>b. Write a function g(x) to represent the price after the 25% markdown. </span>
<span>c. Use a composition function to find the price of an item after both price adjustments that originally costs the boutique $150. </span>
<span>d. Does the order in which the adjustments are applied make a difference? Explain.
</span>
answers
<span>a) f(x) = 1.8x
b) f(x) = 0.75(1.8x)
c) f(150) = 0.75(1.8(150) = $202.50
d) No, it doesn't matter. The result is the same.

Inga needs 3 more years to pay off the whole amount.
<h3>What is the monthly payment?</h3>
A portion of the monthly payment is called the principal, which is the original amount borrowed.
First year balance = $19,691.28
Monthly payment = $273.49
Annual payment = 273.49×12 = $3281.88
Remaining balance after 1 year = 19,691.28 - 3281.88 = $16,409,4
After 3 years balance = $9845.64
- Remaining balance after payment (4 years) = 9845.64-3281.88 = $6563.76
- Remaining balance after payment (5 years) = 6563.76-3281.99 = 3281.88
- Remaining balance after payment (6 years) =3281.88-3281.88 = 0
Hence, Inga needs 3 more years to pay off the whole amount.
