The area of the rubber coating for a flat roof was 96 ft². The rectangular frame the carpenter built for the
flat roof has dimensions such that the length is 4 ft longer than the width. What are the dimensions?

Answers

Answer:

Length = 12 ft.

Width = 8 ft.

Step-by-step explanation:

Given :

Area = 96 ft²Length = Width + 4 ft.

Let :

Length = (x + 4) ft.Width = x ft.

Solving :

The formula for calculating area is : Area = Length x Width96 = (x + 4)(x)x² + 4x - 96 = 0x² + 12x - 8x - 96 = 0x(x + 12) - 8(x + 12) = 0(x - 8)(x + 12) = 0x - 8 = 0 ⇒ x = 8

The dimensions are :

Length = 12 ft.

Width = 8 ft.

and Sunday?

Answers

The total number of miles Finley rode the bus on Saturday and Sunday is 7.98 miles

Calculating distance

From the question, we are to determine the total distance travelled by Finley on Saturday and Sunday

From the given information,

On Saturday, Finley rode the bus from her apartment 3.35 miles to the city park and then 2.51 miles to the library

Total distance travelled on Saturday = 3.35 miles + 2.51 miles

Total distance travelled on Saturday = 5.86 miles

Also,

On Sunday, Finley rode the bus 2.12 miles to the art museum

Total distance travelled on Sunday = 2.12 miles

∴ Total distance travelled on Saturday and Sunday = 5.86 miles + 2.12 miles

Total distance travelled on Saturday and Sunday = 7.98 miles

Hence, the total number of miles Finley rode the bus on Saturday and Sunday is 7.98 miles.

Find the sum of the first 14 terms of the finite geometric series given as:
0.5+ (-1) +2+...

Answers

The sum of the first 14 terms of the finite geometric series 0.5+ (-1) +2+... is -2730.5

How to determine the sum of the series?

The series is given as:

0.5+ (-1) +2+...

The above series is a geometric series, with the following parameters:

First term, a = 0.5Common ratio, r = -2Number of terms, n = 14

The sum of the first 14 terms is calculated using:

[tex]S_n= a *(1 - r^n) \div (1 - r)[/tex]

So, we have:

[tex]S_{14}= 0.5 *(1 - (-2)^{14}) \div (1 + 2)[/tex]

-. The side views of two different ramps are shown below. Which is a true
tatement about the slope of the ramps?

Answers

The statement that is true about the slope of the ramps is: A. Slope of ramp A = slope of ramp B.

What is the Slope?

Slope = gradient = rise / run = vertical distance / horizontal distance.

Slope of the side view of ramp A = rise / run = 20 / 30 = 2/3.

Slope of  the side view of ramp B = rise / run = 14 / 21 = 2/3.

The slope of A = slope of B = 2/3

The statement that is true of the slopes of both ramps is therefore: A. Slope of ramp A = slope of ramp B.

If ɑ and β are roots of 2x² - 5x + 7, then

2x² - 5x + 7 = 2 (x - ɑ) (x - β)

Expanding the right side and matching up coefficients, it follows that

2ɑβ = 7   ⇒   ɑβ = 7/2

-2 (ɑ + β) = -5   ⇒   ɑ + β = 5/2

Now consider a polynomial whose roots are 3ɑ + 4β and 4ɑ + 3β, which can be written with factorization

(x - (3ɑ + 4β)) (x - (4ɑ + 3β))

and expanded to get

x² - (7ɑ + 7β) x + (3ɑ + 4β) (4ɑ + 3β)

Expand/factor the coefficients to rewrite them in terms of the known relations above.

x² - 7 (ɑ + β) x + (12ɑ² + 25ɑβ + 12β²)

x² - 7 (ɑ + β) x + 12 (ɑ² + β²) + 25ɑβ

Recall the square of a binomial,

(x + y)² = x² + 2xy + y²

so we rewrite the latter quadratic as

x² - 7 (ɑ + β) x + 12 ((ɑ + β)² - 2ɑβ) + 25ɑβ

x² - 7 (ɑ + β) x + 12 (ɑ + β)² + ɑβ

Then substituting the expressions whose values we know, we get

x² - 7 (5/2) x + 12 (5/2)² + 7/2

= x² - 35/2 x + 157/2

which we can multiply by 2 to get integer coefficients like in the given quadratic,

= 2x² - 35x + 157

Victoria wants to purchase a tablet. She has $130 to spend. She finds one that regularly sells for $139.99 and is on sale of 15% off. Sales tax is 7%. How much will Victoria pay for the tablet? Show your work and record your answer in the red box.

Answers

Answer:

$127.32

Step-by-step explanation:

Selling price= $139.99

Sale discount= 15% = $139.99 * 0.15 = $21

Discounted price= $139.99 - $21 = $118.99

Sales tax added= 7% = $118.99 * 0.07 = $8.33

Victoria has to pay = $118.99 + $8.33 = $127.32 so she has enough money to buy it with $2.68 left
