Answer:

9/2π cm/s

Step-by-step explanation:

Volume of the spherical balloon V= 4/3πr³

Rate of change of volume dV/dt = dV/dr * dr/dt

dV/dr = 3(4/3πr²)

dV/dr = 4πr²

dV/dr = 4π(2)²

dV/dr = 16π

If V = 72cm²/s

72 = 16π*dr/dt

dr/dt = 72/16π

dr/dt = 9/2π cm/s

Hence the radius is changing at  9/2π cm/s

Find the measures of the numbers angles in each rectangle

Answers

Answer:

m<1 = 60°

m<2 = 30°

m<3 = 90°

Step-by-step explanation:

Recall some properties of Rectangle. Thus:

The four angles of a rectangle are right angles = 90° each.

Opposite sides of a rectangle are also parallel to each other.

With the knowledge of these, we can solve for angles 1, 2, and 3.

Thus:

m<1 = 60° (alternate interior angles are congruent)

m<2 + m<1 = 90° (complementary angles)

m<2 + 60° = 90° (substitution)

m<2 = 30° (substraction property of equality)

m<3 = 90° (angle of a rectangle)

Dedra polled people at the mall to determine which types of movies
they preferred to watch. She displayed the results in a circle graph.

Of the people polled, 120 preferred to
to watch action movies. Use this information and
the graph to answer these questions.
a) What is the total number of people
Dedra polled?

Answers

The total number of people Dedra polled is 400.

Given,

Number of people preferred to watch action movies = 120

We have to find the total number of people Dedra polled:

According to the given circle graph:

Percentage of people preferred to watch action movies = 30%

Now,

The total number of people polled = x

Then,

30% of x ix 120.

So,

x = (120 × 100) / 30

x = 4 × 100

x = 400

Therefore the total number of people Dedra polled is 400.

Lets check the others also:

Comedy: 35%

∴ (400 × 35) / 100 = 4 × 35 = 140

140 people preferred to watch comedy movies.

Drama: 20%

∴ (400 × 20) / 100 = 4 × 20 = 80

80 people preferred to watch drama movies.

Fantasy: 10%

∴ (400 × 10) / 100 = 4 × 10 = 40

40 people preferred to watch fantasy movies.

Horror: 5%

∴ (400 × 5) / 100 = 4 × 5 = 20

20 people preferred to watch horror movies.

The total number of people Dedra polled is 400

The coordinates of points A and B are A (-10,-8) and B (80, 37). Which are the
coordinates of a point that partitions segment AB in a ratio of 4:5?

Answers

Given that,

The coordinates of A = (-10,-8)

The coordinates of B = (80,37)

To find,

The coordinates of a point that partitions segment AB in a ratio of 4:5.

Solution,

Let the coordinate of required point is (x,y). We can use section formula to find it as follows :

The section formula is :

[tex](x,y)=(\dfrac{m_2x_1+m_1x_2}{m_1+m_2},\dfrac{m_2y_1+m_1y_2}{m_1+m_2},)[/tex]

We have,

m₁ =4, m₂ = 5, x₁ = -10, x₂ = 80, y₁ = -8, y₂ = 37

Using all the values,

[tex](x,y)=(\dfrac{5(-10)+4(-10)}{4+5},\dfrac{5(-8)+4(37)}{4+5})\\\\=(-10,12)[/tex]

So, the required point in which AB is divided is (-10,12)

Given that,

Slope, m = -3/5

To find,

The slope intercept form of the equation of the line.

Solution,

The general form of equation is :

We have, x = -5, y = 3

So,

[tex]3=\dfrac{-3}{5}(-5)+b\\\\3=-3+b\\\\b = 6[/tex]

The equation is :

Addition of integers is the process for finding out the sum of more than two variables. There may be an increase or decrease in value, depending on whether the integers are positive or negative or a mixture

Addition in mathematics is one out of the four basic mathematical operations used for adding of two numbers.

Rules for addition of integers

• The sum of an integer and its additive inverse is 0.

• Addition of two positive integers always result in a positive value that is always greater than both the integers.

• Adding two negative values always result in a positive value what is smaller than the given numbers.

• Adding 0 to any numbers results the same number.

Mr Allen has $149 in his account and he need to write a check of $169 . It is not possible because 149 < 169 , he must have money more than or equal to $169 for paying the bill.

What is 25% of 2,000

Answers

500! You just multiply 25% x 2,000. Hope this helped love!

Answer:

500

Step-by-step explanation:

= (25/100)*2000

= (25*2000)/100

= 50000/100 = 500

Step 1: In the given case Output Value is 2000.

Step 2: Let us consider the unknown value as x.

Step 3: Consider the output value of 2000 = 100%.

Step 4: In the Same way, x = 25%.

Step 5: On dividing the pair of simple equations we got the equation as under

2000 = 100% (1).

x = 25% (2).

(2000%)/(x%) = 100/25

Step 6: Reciprocal of both sides results in the following equation

x%/2000% = 25/100

Step 7: Simplifying the above-obtained equation further will tell what is 25% of 2000

x = 500%

Therefore, 25% of 2000 is 500
