A computer originally priced at $850 is on sale for 15% off. What is the sale price of the computer?
Answer:
Sale price: $722.50
Step-by-step explanation:
Subtract 15% from 100%, obtaining 85%. The computer is sold for 85% off.
Converting this 85% to a mixed decimal, we get 0.85, and then we multiply the original price ($850) by this 0.85: 0.85($850) = $722.50

Meagan and jake both live on the same street that the librarian is on.Megan lives 3.5 blicks north of the library,and jake lives 4.5 blocks south of the library.How many blpcks apart do jake and meagan live.
Answer:
8 blocks
Step-by-step explanation:
As the north direction is upwards and the south direction is downwards the total distance between the two people 's (Megan and Jake) houses will be obtained by adding their distances from the library which is in the middle as shown in the diagram.
Hence total distance between the two houses= 3.5 + 4.5= 8 blocks
Jake and Meagan live 8 blocks apart.

A rectangle has dimensions 8ft x 12ft. It is dilated by a scale factor and has new dimensions of 32 ft x 48 ft. What was the scale factor?
Given:
A rectangle has dimensions 8ft x 12ft.
After dilatation the new dimensions of 32 ft x 48 ft.
To find:
The scale factor of the dilation.
Solution:
We know that,
[tex]\text{Scale factor}=\dfrac{\text{Side length of new figure}}{\text{Corresponding side length of original figure}}[/tex]
Dimensions of original rectangle are 8ft x 12ft and dimensions of the new rectangle are 32 ft x 48 ft. Corresponding side of 8ft is 32 ft and corresponding side of 12 ft is 48 ft.
[tex]\text{Scale factor}=\dfrac{32}{8}[/tex]
[tex]\text{Scale factor}=4[/tex]

4x2+ 12 x= 28
Answer:
x = sqrt(37)/2 - 3/2
approximately 1.54
Step-by-step explanation:
Solve for x over the real numbers:
4 x^2 + 12 x = 28
Divide both sides by 4:
x^2 + 3 x = 7
Add 9/4 to both sides:
x^2 + 3 x + 9/4 = 37/4
Write the left hand side as a square:
(x + 3/2)^2 = 37/4
Take the square root of both sides:
x + 3/2 = sqrt(37)/2 or x + 3/2 = -sqrt(37)/2
Subtract 3/2 from both sides:
x = sqrt(37)/2 - 3/2 or x + 3/2 = -sqrt(37)/2
Subtract 3/2 from both sides:
Answer: |
| x = sqrt(37)/2 - 3/2 or x = -3/2 - sqrt(37)/2

The integral expression of the form ∫ f(x) · dg is equal to the composite expression f(x) · g(x) - ∫ g(x) df by applying integration by parts method. (Correct choice: A)
How to derive the rule of integration by parts
In this question we must derive a integration rule for the product of two functions that are integrable. The integration by parts method is inspired on the differentiation rule for the product of two differentiable functions, whose definition is shown below:
[tex]\frac{d}{dx} [f(x)\cdot g(x)] = f'(x) \cdot g(x) + f(x)\cdot g'(x)[/tex] (1)
If we integrate and used integral Calculus theorem on both sides of (1), then we have the following expression:
f(x) · g(x) = ∫ g(x) · df + ∫ f(x) · dg
∫ f(x) · dg = f(x) · g(x) - ∫ g(x) df
Therefore, the integral expression of the form ∫ f(x) · dg is equal to the composite expression f(x) · g(x) - ∫ g(x) df by applying integration by parts method. (Correct choice: A)

A rectangle has a length of 11 inches less than 8 times its width. If the area of the rectangle is 4344 square inches, find the length of the rectangle.
Answer:
181 inches
Step-by-step explanation:
A rectangle has a length of 11 inches less than 8 times its width. If the area of the rectangle is 4344 square inches, find the length of the rectangle.
The formula for Area of a rectangle = Length × Width = L × W
A rectangle has a length of 11 inches less than 8 times its width.
L = 8W - 11
A = 4344
Hence,
4344 = (8W - 11)W
4344 = 8W² - 11W
Hence:.8W² - 11W - 4344
We factorise
(8W+181)(W−24)
W - 24 = 0
W = 24 inches
Solving for Length
L = 8W - 11
L = 8 × 24 - 11
L = 181 inches

16. Geography If a ship sailed due south from Iceland to Antarctica, it would sail
through an angle of rotation of about 140° around Earth's center. Find this measure in
radians. Then, using 3960 miles for Earth's radius, find how far the ship would travel.
Answer:
9674.28 miles
Step-by-step explanation:
From the above question, we are given:
Central angle = 140°
Radius = 3960 miles
We are to solve for the distance = Arc length
The formula for Arc length when your central angle is in radians
r × θ
θ = 140°
Converting 140° to radians
140° × π/180 = 2.443rad
Hence,
3960 × 2.443 rad
= 9674.28 miles
The ship would travel 9674.28 miles.
