Answer:

Tim read 54 pages on Thursday.

Step-by-step explanation:

Consider the provided information.

Tim read 2 pages on Monday. Each day after that, he reads triple the number of pages as the previous day.

Monday = [tex]2=2[/tex]

Tuesday = [tex]2\times 3=6[/tex]

Wednesday = [tex]2\times 3\times 3=18[/tex]

Thursday = [tex]2\times 3\times 3\times 3=54[/tex]

Hence, Tim read 54 pages on Thursday.

How many pages does Tim read on Monday? 2 pages.

If Tim tripled the amount that he read on Monday, how many pages did he read on Tuesday? 2 × 3 = 6 Pages

Repeat for Wednesday. 6 × 3 = 18 Pages

Repeat for Thursday. 18 × 3 = 54 Pages

Answer:

a) The polynomial for the perimeter of the rectangle is = 14a - 2b

b) 150

Step-by-step explanation:

a) The formula for the area of a rectangle is given as:

P = 2L + 2W

From the question:

The length of a rectangle = 4a+3b

The width of a rectangle = 3a-2b.

The Perimeter of the rectangle is

Perimeter = 2(4a + 3b) + 2(3a - 2b)

Perimeter = 8a + 6b + 6a - 4b

Perimeter = 8a + 6a + 6b - 4b

Perimeter = 14a - 2b

Hence:

The polynomial for the perimeter of the rectangle is = 14a - 2b

b) What is the minimum perimeter of the rectangle if a=12 and b is a non-zero whole number?

Non-zero whole number are single digit number such as: 1, 2, 3, 4, 5, 6, 7, 8, 9

The perimeter of the rectangle is = 14a - 2b

We are asked to find the minimum perimeter of the rectangle if a=12 and b is a non-zero whole number.

In order to solve this, we would used the highest non zero whole number which is 9

Hence,

For a = 12 , b = 9

14 × 12 - 2(9)

= 168 - 18

= 150

Hence, the minimum perimeter of the rectangle if a=12 and b is a non-zero whole number is 150

Answer:

Perimeter = 5 + 5 + 7.1 + 10 =27.1

area = (5 + 10)x5  / 2 = 37.5

Step-by-step explanation:

Slope formula: m = (x' - x)/(y' - y)

m-AD: (6-3)/(-5 - -9) = 3/4    (I'm not detail other Other slopes)

m- BC = 3/4

m-AB = - 4/3

m-AD = m-BC         AD // BC      (ABCD is a Trapezoid)

m-AB = - 1 / m-BC

AB ⊥ BC

segment length formula: d = √(x' - x)² + (y' - y)²

AD = √(-5 - -9)² + (6 - 3)² = √4² + 3² = √25 = 5

DC = √50 = 7.1

BC = √100 = 10

AB = √25 = 5

Perimeter = 5 + 5 + 7.1 + 10 =27.1

area = (5 + 10)x5  / 2 = 37.5

area ABCD = (5+10)x5  / 2 =

tan(A/2)

tan(A/2)=sinA/1+cos A

tan(A/2)= 5/13÷1+12/13

tanA/2=1/5

Answer:

tan([tex]\frac{A}{2}[/tex] ) = ± [tex]\frac{1}{5}[/tex]

Step-by-step explanation:

Using the trigonometric identity

tan ([tex]\frac{A}{2}[/tex] ) = ± [tex]\sqrt{\frac{1-cosA}{1+cosA} }[/tex]

Given

tanA = [tex]\frac{5}{12}[/tex] = [tex]\frac{opposite}{adjacent}[/tex]

This is a right triangle 5- 12- 13 ( with hypotenuse 13 ), then

cosA = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{12}{13}[/tex] , then

tan ([tex]\frac{A}{2}[/tex] )

= ± [tex]\sqrt{\frac{1-\frac{12}{13} }{1+\frac{12}{13} } }[/tex]

= ± [tex]\sqrt{\frac{\frac{1}{13} }{\frac{25}{13} } }[/tex]

= ± [tex]\sqrt{\frac{1}{25} }[/tex]

= ± [tex]\frac{1}{5}[/tex]

The value of n in the given triangle is 11.

The incenter is one of the triangle's points of concurrency formed by the intersection of the triangle's 3 angle bisectors.

Given that, triangle DEF, where A is the incenter of the triangle, we need to find the value of n,

Since we know that, incenter is a point in triangle where all the angle bisector meets, therefore,

3n-6 = 27

3n = 33

n = 11

Hence, the value of n in the given triangle is 11.

Answer:

The length of the road in the model is 60 m.

Step-by-step explanation:

Given: scale = 1:19

         real-life length of the road = 1.14 km

                                                      = 1140 m

Let the length of the road in the model be represented by d. A scale is a representative fraction that can be used to either increase or decrease the length of an object.

Scale = [tex]\frac{length on drawing}{actual length}[/tex]

The actual length is the real-life length given as 1140 m.

So that,

[tex]\frac{1}{19}[/tex] = [tex]\frac{d}{1140}[/tex]

19d = 1140

⇒ d = [tex]\frac{1140}{19}[/tex]

       = 60

Therefore, the length of the road in the model is 60 m.

Answer:

No, Noah used the diameter instead of the radius in the calculations.

V = 91.13π

Step-by-step explanation:

Noah is working on a geometry problem that involves finding the volume of a sphere with a diameter of 9 units. His work is shown below.

V = πr3

V = π(9)3

V = π(729)

V = 972π cubic units

Is Noah’s work correct

Volume of a sphere, V = πr³

radius, r = diameter / 2

Diameter = 9 units

r = 9 / 2

= 4.5 units

Volume of a sphere, V = πr³

= π × 4.5³

= π × 91.125

= 91.125π

Approximately 91.13π

V = 91.13π

No, Noah used the diameter instead of the radius in the calculations.

Answer:

no, he used radius instead of diameter

Answer:

B.

Step-by-step explanation:

slope = Rise  (y difference) / Run (x difference)

B, Rise = 3   run = 2 slope = 3/2

The graph with a line of slope 3/2 is graph B.

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Slope can also be defined as the tangent of the angle that the line is making with the positive X axis.

Slope of a line with two points (x, y) and (x', y') on the lines is,

Slope = (y' - y) / (x' - x)

Take any two points from all the three graphs given to find the slope.

A. Two points are (0, 4) and (6, 8)

Slope = (8 - 4) / (6 - 0) = 4 / 6 = 2/3

B. Two points are (0, 0) and (4, 6)

Slope = (6 - 0) / (4 - 0) = 6/4 = 3/2

C. Two points are (0, 2) and (2, 8)

Slope = (8 - 2) / (2 - 0) = 6/2 = 3

Hence the graph B has slope equals 3/2.
