Answer:

It is best to solve a system of equations using substitution when one of the equations isolates one of the variables, or when the coefficient of one of the variables is 1 or -1.

Step-by-step explanation:

This makes it easier to substitute one variable for the other, allowing you to solve for the remaining variable. It is also a good idea to check the solution back in the original equations just to make sure it is a valid solution

Answer:

Answer Below

Step-by-step explanation:

It is best to use substitution if one of the variables is isolated or has a coefficient of 1 or -1.

Answer:

160 in³

Step-by-step explanation:

Volume of rectangular pyramid, V = (Length * width * height) / 3

Length = 10 in ; width = 8 in ; height = 6 in

V = (10 * 8 * 6) / 3

V = 160 in³

Sales Tax = $3.00

The total amount paid by the group was $48.15

The amount of the sales tax can be calculated by multiplying the pre-tax bill of $37.50 by the sales tax rate of 8%:

Sales tax = $37.50 * 8% = $3.00

The total amount paid including tax and tip can be calculated by adding the amount of the sales tax to the pre-tax bill and then calculating the tip on the new total:

Total = $37.50 + $3.00 + ($37.50 + $3.00) * 18% = $37.50 + $3.00 + $7.65 = $48.15

So the total amount paid by the group was $48.15.

Answer:

110 in.²

Step-by-step explanation:

The figure is composed of a parallelogram and a rectangle

Therefore, the area of the figure = area of rectangle + area of parallelogram

= Length*Width + base*height

Length = 10 in.

Width = 6 in.

base = 10 in.

height = 5 in.

Area of the figure = 10*6 + 10*5

= 60 + 50

= 110 in.²

Step-by-step explanation:

2010: 450,000

2011: (5% of 450,000) + 450,000 = 472,500

2012: (5% of 472,500) + 472,500 = 496,125

2013: (5% of 496,125) + 496,125 = 520,931.25

2014: (5% of 520,931.25) + 520,931.25 = 546,977.8125

2015: (5% of 546,977.8125) + 546,977.8125 = 574,326.703125

2015: (5% of 574,326.703125) + 574,326.703125 = 603,043.038281

2016: (5% of 603,043.038281) + 603,043.038281 = 633,195.190195

2017: (5% of 633,195.190195) + 633,195.190195 = 664,854.949705

2018: (5% of 664,854.949705) + 664,854.949705 = 698,097.69719

2019: (5% of 698,097.69719) + 698,097.69719 = 733,002.582049

Answer:

yes it is

Step-by-step explanation:

The nearest integer that is a solution, gotten through graphing of the quadratic function x² + 2x - 2 = 5, is x = -4

Quadratic equations when plotted on a graph follows a parabolic path.

To plot the functions there will be table of values that is used in making the graph. The table of values is solved as follows

x² + 2x - 2 = 5 rearranging the equation will result to x² + 2x - 7 = 0

For x = -20,  y = (-20)² + 2 * -20 - 7 = 353

For x = 0,  y = (0)² + 2 * 0 - 7 = -7

For x = 20,  y = (20)² + 2 * 20 - 7 = 433

x      y

-20  353

0      -7

20    433

The graph is plotted and attached. From the graph the solution is

x = -3.828, to the nearest integer = -4

Answer:

14.1 inches

Step-by-step explanation:

The formula to be used to find the arc length is Ф = s(arc length) / r(radius)

First we rearrange the formula to find the arc length which would be s = Ф * r

This formula only works in radians so the first step is converting 135° to radians so we would do 135° * π radians/180° which would give us 3π/4

We would then multiply 3π/4 * 6 and get 18π/4,  plugging that value into a calculator returns us a value of ≈ 14.137

We then round to the nearest tenth and get an answer of 14.1 inches for the arc length of the circle below

Answer:

62ft²

Step-by-step explanation:

Hi there!

Surface area is calculated by this formula:

2(length*width)+2(width*height)+2(length*height)

*note: we multiply each area by 2, as the prisim has 6 faces, or 2 of each face

we're given a length of 5 ft, a width of 2 ft, and a height of 3ft

now let's calculate the surface area

to find the area of the first two faces:

2(length*width)

2(5*2)

2(10)

20 ft²

now to find the area of the second two faces:

2(width*height)

2(2*3)

2(6)

12 ft²

finally, find the area of the last two faces:

2(length*height)

2(3*5)

2(15)

30 ft²

now add up all the values

SA=20+12+30=62 ft²

your answer is 62ft²

Answer:

Years = {log(total) -log(Principal)} ÷ log(1 + rate)

Years = [log (200,000) -log (20,000)] / log (1.09)

Years = [5.3010299957 -4.3010299957] /  0.037426497941

Years = 1 / 0.037426497941

Years = 26.7190374471

*************************************************

Finding Doubling Time : (We'll calculate $100 becoming $200)

Years = {log(total) -log(Principal)} ÷ log(1 + rate)

Years = log (200) -log (100) / log(1.09)

Years =  (2.3010299957 -2) / 0.037426497941

Years = .3010299957 / 0.037426497941

Sry,if i misunderstood the question.. do let me know in the comment section

Answer:

40.5 m²

Step-by-step explanation:

Area of the shaded = area of the square - area of the triangle

Area of square = s²

s = 9 m

Area of square = 9² = 81 m²

Area of triangle = ½*b*h

b = 9 m

h = 9 m

Area of triangle = ½*9*9 = 40.5 m²

Area of the shaded = 81 - 40.5 = 40.5 m²
