Answer:
I believe it's 25% .............
Answer:
40%
Step-by-step explanation:
The cash price = $4,250
If Steve rents the computer for $595 for 10 months he would have to spend $595 x 10 = $5,950
The difference in money = 5950 - 4250 =$1700
As a percentage of the cash price this would be
1700/4250 x 100 = 40%
Answer:
Rent option is 40% more than the cash price 40%
We can verify this by noting that if there is an increase of r% in the price of an item then
Increased price = Old price + Increase
= Old price + Old price x r/100
In this case, Old price = 4250
r = 40%, r/100 = 0.04
New price = 4250 + 4250 x 0.04 = 4250(1 + 0.04) = 4250(1.04) = 5950 which tallies with given figures
7. Solve the formula A = 1/2bh
for b. Justly each step. Then find the base of a triangle whose
area is 952 square feet and whose height is 56 feet.
The formula A = 1/2bh in terms of A and h is b = 2A/h and the measure of the base length is 34 feet.
What is the triangle?In terms of geometry, a triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
It is given that:
The formula A = 1/2bh
It is required to solve for b:
2A = bh
b = 2A/h
Plug A = 952 square feet
h = 56 feet
b = 2(952)/56
b = 34 feet
Thus, the formula A = 1/2bh in terms of A and h is b = 2A/h and the measure of the base length is 34 feet.

Felipe has a business where he builds and sells birdhouses. To build 12 birdhouses, he needs \large 5\frac{1}{4} meters of wood. During the holiday season, Felipe was asked to make \large 4\frac{1}{2} times the number of birdhouses he usually makes. How many meters of wood does Felipe need to make that many birdhouses?
Based on the number of birdhouses that Felipe has to build in the holiday season, the meters of wood that Felipe needs would be 23 ⁵/₈ meters
How many meters of wood are needed?First, find out the number of birdhouses Felipe needs to make:
= Normal number of birdhouses x Increase in holiday season
= 12 x 4¹/₂
= 54 birdhouses
The meters of wood he needs are:
= Number of birdhouses to be made / Number of bird houses he usually makes x Meters of wood needed for birdhouses Felipe usually makes

Find the inverse of each function. Is the inverse a function? f(x)=(x+3)²+1
Inverse of the given function F(x) = ( x + 3 )² + 1 is F⁻¹(x) = [√( x - 1 ) ] - 3
Given is a function of x, F(x) = ( x + 3 )² + 1
These question can be solved by following 4 easy steps
Step 1 : Switch the F(x) with the variable y
This implies, F(x) = ( x + 3 )² + 1 becomes y = ( x + 3 )² + 1
Step 2 : Interchange the variable x and y in the above obtained equation
This implies, from the equation y = 3 x³- 4, we get
x = ( y + 3 )² + 1
Step 3 : Solve the new obtained equation for y
This implies, we have to simplify the equation by rearranging the terms to get the equation in terms of the variable x.
x = ( y + 3 )² + 1
=> x + 1 = (y + 3 )²
=> (y + 3 )² = x + 1
=> y = √( x - 1 ) - 3
Hence we obtain the required equation.
Step 4 : Switch the variable y with F⁻¹(x)
This implies, y =√( x - 1 ) - 3 becomes F⁻¹(x) = √( x - 1 ) - 3
Therefore, we get the inverse of the given function F(x) = ( x + 3 )² + 1 as F⁻¹(x) = √( x - 1 ) - 3

The answer to this question is: og(x³y⁵) = 3log(x) + 5log(y)
In mathematics, the logarithm is that the function to exponentiation. which means the logarithm of a given number x is that the exponent to which another fixed number, the base b, must be raised, to supply that number x. within the simplest case, the logarithm counts the amount of occurrences of the identical consider repeated multiplication
To solve this question, we need only 2 identities, i.e.,
log(a*b) = log(a) + log(b) ...(1)
log(aⁿ) = nlog(a) ...(2)
Using 1, we can expand log x³ y⁵ as: log x³ y⁵ = log(x³) + log(y⁵) ...(3)
Using 2, we can expand both the terms as: log(x³) = 3log(x)log(y⁵) = 5log(y)
Putting them in equation 3, we get:3log(x) +5log(y)

Which percent of increase is greater: the percent of increase for the perimeter of the square or the percent of increase for the area? How much greater?
Based on the information, the percentage increase for the area s greater as it is 600% greater
How to illustrate the information?Here, we have a square of side length 3 cm
The area of the square is 3² = 9 cm²
Perimeter of the square = 4L = 4 * 3 = 12 cm
When we triple the length of the square, its new length becomes 3 ,× 3 = 9 cm
Area here will be 9 * 9 = 81 cm²
Perimeter = 4 L = 4 * 9 = 36cm
To calculate percentage change, we use the formula;
(new value - old value)/old value * 100%
For the perimeter;
(36-12)/12 * 100% = 24/12 * 100% = 2 * 100% = 200%
For the area;
(81-9)/9 * 100% = 72/9 * 100% = 8 * 100% = 800%
The percentage increase of the area is greater by: 800% - 200% = 600%

The temperature in the late afternoon was -7.5 Celsius. It dropped 8.5 degrees by midnight. What was the temperature at midnight?
The answer to the question is T= - 7.5°C - 8.5°C = -16°C
The initial temperature in the late afternoon was -7.5°C.
It dropped by 8.5 degrees by midnight.
Change in temperature (in midnight) = -8.5°
Here negative sign represents the decrease in the temperature
.Let T be the total change in the temperature.
So, total change in the temperature is T = - 8.5°C
Therefore the required temperature in the midnight =temperature in late afternoon+the temperature dropped in night.
