Is Noah's work correct? Explain. Yes, Noah's calculations are correct. No, Noah did not simplify correctly. No, Noah used the diameter instead of the radius in the calculations. No, Noah did not use the correct formula for volume of a sphere.

Answers

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

Below, explain why we are allowed the
"substitute in" x - 3 for y in the top equation.
Why is this useful for finding our first solution?
x + y = 11
y = x - 3

Answer:

because in the bottom eqution it shows us x-3=y therefor we could re-write the top equation as x+x-3=11

Determine what shape is formed for the given coordinates for ABCD, and then find the perimeter and area as an exact value and rounded to the nearest tenth.

A (−9, 3), B (−6, −1), C (2, 5), D (−5, 6)

Answers

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 =

Which graph shows a line with the slope of 3/2?

Answers

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.

What is Slope?

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.

332 + 25 = 33r - 25
Which is no solution

Answers

Answer:

A, B & D

Step-by-step explanation:

Because if you subtract one of the constants from both sides then you should only have equal variables. In other words, both sides have to be identical in this situation.

33x-33= 33x + 25

33x = 33x + 58 No matter what you make x, the right will be 58 bigger than the right so there is no solution.

33x+33=33x+25

33x+8= 33x nope no solution

33x+25=33x+25

33x = 33x both sides identical so there is a solution

33x-25 = 33x +25

33x= 33x+50

Answer:

  x = 78

Step-by-step explanation:

The base angles of an isosceles triangle are congruent, so the sum of angles is ...

  x° +x° +24° = 180°

  2x +24 = 180 . . . . . collect terms

  x + 12 = 90 . . . . . . . divide by 2

  x = 90 -12 . . . . . . . . subtract 12

Additional comment

The base angle of an isosceles triangle is always the complement of half the third angle. That angle's bisector is an altitude, so divides the isosceles triangle into two congruent right triangles.

Tim is reading a book. On Monday he reads 2 pages. On each day after that, he reads triple the number of pages as the previous day. How many pages did Tim read on Thursday?

Answers

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
