Answers

Answer:

81 cm ^3

Step-by-step explanation:

The volume of a cone is given by

V = 1/3 pi r^2 h where r is the radius and h is the height

We are given the diameter of 6 so the radius is 1/2 the diameter

r = 1/2 (6) = 3

V = 1/3 pi r^2 h

   = 1/3 ( 3) * (3) ^2 * 9

Laiba, tauseef and Nadia walked 24,42 and 52 meters.What is the minimum distance that each of them can cover equally ?

Answers

Answer:

the minimum distance each of them can cover equally is 8 m.

Step-by-step explanation:

Given;

different distance covered by Laiba, tauseef and Nadia = 24 m, 42 m and 52 m

for the 24 m, distance covered by each = 24 m/3 = 8 m

for the 42 m, distance covered by each, = 42 m/3 = 14 m

for the 52 m, distance covered by each, = 52 m/3 = 17.33 m

From the results above, the minimum distance each of them can cover equally is 8 m.

Find the factorization of the polynomal below 64x^2 + 48x + 9

Answers

Answer:

(8x + 3)²

Step-by-step explanation:

Since our polynomial is 64x² + 48x + 9, we multiply 64x² by 9 to get 64x² × 9 = 576x² since we cannot simplify the expression any further.

Next, we need to find the factors of 576x² that add up to give 48x, these are 24x and 24x.

So the expression is re-written as

64x² + 48x + 9 = 64x² + 24x + 24x + 9

Writing out all the common factors, we have,

64x² + 48x + 9 = 8x × 8x + 3 × 8x + 3 × 8x + 3 × 3

Factorizing we have

64x² + 48x + 9 = 8x(8x + 3) + 3(8x + 3)

64x² + 48x + 9 = (8x + 3)(8x + 3)

64x² + 48x + 9 = (8x + 3)²

Joan spilled 750ml of fruit punch while pouring into cups from a bucket which held 3.75 litres of punch. Calculate what % of punch was spilled

Answers

Answer:

Percentage of punch spilled = 20%

Step-by-step explanation:

1 liter = 1000 ml

750 ml = 750/1000

= 0.75 liter

Quantity of fruit punch spilled = 0.75 liter

Total volume of fruit punch in the bucket = 3.75 liters

Calculate what % of punch was spilled

Percentage of punch spilled = quantity of punch spilled / Total quantity of punch × 100

= 0.75 liter / 3.75 liters × 100

= 0.2 × 100

= 20%

Percentage of punch spilled = 20%

O B. an = 5+(n-1)(-8)
O C. an=-8+ (n - 115
O D. an= -8+ (n - 1)(-5)

Answers

Answer:

[tex]\text{C. }a_n=-8+(n-1)5[/tex]

Step-by-step explanation:

The explicit formula for an arithmetic sequence is given by [tex]a_n=a_1+(n-1)d[/tex], where [tex]a_n[/tex] is the [tex]n[/tex]th, [tex]a_1[/tex] is the first them of the sequence, and [tex]d[/tex] is the common difference.

In the given sequence -8, -3, 2, 7, we can see that we're adding 5 to each term. Therefore, the common different is positive five (+5). We can also identify the first term is -8. Therefore, we have:

[tex]a_1=-8[/tex] [tex]d=5[/tex]

Thus, the explicit formula for this sequence is:

[tex]\boxed{a_n=-8+(n-1)5}[/tex]

Question 1

Answers

Answer:

DC = 2

Step-by-step explanation:

From the diagram, AD (i.e the angle bisector) bisects the angle into 2 equal parts. Thus, BD and DC are equal.

BD = 2

DC = BD = 2

DC = 2

This can further be explained as illustrated below:

We'll begin by calculating AD. This can be obtained as follow:

Angle A = 30°

Opposite = BD = 2

Hypothenus = AD =?

Sine A = Opposite (BD) /Hypothenus (AD)

Sine 30 = 2 / AD

0.5 = 2 / AD

Cross multiply

0.5 × AD = 2

Divide both side by 0.5

AD = 2 / 0.5

AD = 4

Finally, we shall determine DC. This can be obtained as follow:

Angle A = 30°

Hypothenus = AD = 4

Opposite = DC =?

Sine A = Opposite (DC) /Hypothenus (AD)

Sine 30 = DC / 4

Cross multiply

DC = 4 × Sine 30

DC = 4 × 0.5

DC = 2

What is the slope of this?

Answers

Answer:

-3/2

Step-by-step explanation:

the slope of a line is expressed as ratio y/x showing how many units y changes, when x changes a certain number of units.

so, going from A to B, x changes 4 units (from -3 to +1), and y changes 6 units (down, from +3 to -3). that makes the y change negative.

so, the slope is

-6/4 = -3/2

write the equation for the line that has a slope of -4 and passes through the point (-2, 2)

Answers

Answer:

y = -4x - 6

Step-by-step explanation:

y = -4x + b

2 = -4(-2) + b

2 = 8 + b

-6 = b

Answer: y= -4x+ 6


Step 1: Write an equation

To start off, let’s write the outline for the equation we will need. From my understanding of the question, we will need to put the equation in slope- intercept form. Let’s write the formula now.

y= mx+ b

Step 2: Substitute information

Now that we know the formula, we need to substitute the information we are given. Let’s start with the slope, which is represented in the equation by the letter m.

y= mx+ b
y= -4x+ b

Step 3: Solve

Now let’s solve for b. We will do so by substituting the given point into the equation by changing y and x. We will use that information to solve, which will bring us the only other unknown variable, b. Let’s do this now.

y= -4x+ b
2= -4(-2)+ b
2= 8+ b
6= b

Step 4: Revise equation

We now know the answer for b. We can substitute this into the equation. Since y and x can remain a variable, this will complete our equation.

y= -4x+ 6

D. having students write a definition for each term in their own words in their native language

Step-by-step explanation:

In Mr Fischer's mathematics class, we are presented with two categories of learners. Those that are native speakers of English and those who are learners of English.

Both categories of students would show their understanding best in this lesson if they were to write in their own native language.

The native english-speakers would have no issues writing in English, but those who are English learners would have problems communicating their understanding of the lesson in English. So it is best they give their definitions in their native language.
