Answer:

3 is the right answer because it is less than 4 and greater than 2

Answer:

10 cm

Step-by-step explanation:

To solve this problem, we have to calculate the volume of a hemisphere and the volume of a cylinder and add them together. The volume of the glass can be only be calculated when we find the volume of the hemisphere and the volume of the cylinder and then add then up together.

The volume of a hemisphere is given as

[tex]v = \frac{2}{3} * \pi * r^3[/tex]

Data

Let's substitute the values into the equation and solve.

[tex]v = \frac{2}{3} * \pi * r^3\\v = 56.556cm^3\\[/tex]

The formula of volume of a cylinder is

[tex]v = \pi r^2 h[/tex]

data given

Let's substitute the values into the equation and solve

[tex]v = \pi r^2 h\\v = 3.142 * 3^2 * 3\\v = 84.834cm^3[/tex]

Let's add both volumes together so we have the volume of the glass cup

[tex]56.556 + 84.834 = 141.39cm^3[/tex]

The volume of the glass can be only be calculated when we find the volume of the hemisphere and the volume of the cylinder and then add then up together.

Answer:

18

Step-by-step explanation:

In 6 years, both other their ages will add up to 39. So 12 years back( 6 years for each of them), their combined age will be 27.

Now we have to find the age of Suma. We can find her brother age first.

We can use the equation 2x+x=27

In this equation, x is the age of Suma's brother. 2x + x = 3x.

3x = 27.

27 divided by 3 is 9 so Suma's brother is 9 years old. And since Suma is twice as old. Suma is 18 years old.

Answer:

Suma is 18 years old

Step-by-step explanation:

Let s = Suma's age

Let b = brother's age

Suma is twice as old as her brother:

⇒ s = 2b

In 6 years time, the sum of their ages will be 39 years:

⇒ (s + 6) + (b + 6) = 39

Substitute  s = 2b  into  (s + 6) + (b + 6) = 39  and solve for b:

⇒ (2b + 6) + (b + 6) = 39

⇒ 3b + 12 = 39

⇒ 3b = 27

⇒ b = 9

Substitute found value of b into  s = 2b  and solve for s:

⇒ s = 2(9)

⇒ s = 18

Therefore, Suma is 18 years old and her brother is 9 years old.

Answer:

A term is a single number or variable, in this case, the number 2.

The sum in this equation would be 4x + 2.

The product is the result of multiplication, in this equation, the result of 5(4x + 2).

The factors are the digits that are being multiplied, in this case, 5 & 4x + 2

The quotient is the result of a division, in this case, the result of (4x + 2) / 7y.

A coefficient is a number that is being multiplied by a variable, in this case, 4 & y.

The standard error is an estimate of the standard deviation of the sampling distribution. The value of the standard error of the mean is 387.970.

It is an estimate of the standard deviation of the sampling distribution. It measures the variability of a considered sample statistic.

Suppose that we're given that:

Population standard deviation = σ

Size of the sample we're working on = n

Then, the standard error can be calculated as:

[tex]SE = \dfrac{\sigma}{\sqrt{n}}[/tex]

where SE denotes the standard error.

The standard error of the mean can be written as,

SE = σ/√n

SE = 2,125/√30

SE = 387.970

Hence, the value of the standard error of the mean is 387.970.

Part A:

When drawn on graph, we can identify it is a right angle triangle.

Or use Pythagoras Theorem:

10² + 5² = (5√5)²

125 = 125... Hence it is a right angle triangle confirmed.

Part B:

Area of triangle = ½ × base × height = ½ × 10 × 5 = 25 units²

Part C:

Total Sum or measure of all sides: 5 + 10 + 5√5 = 15 + 5√5 units

Answer:

Answer: 160 seconds

Step-by-step explanation:

First let us find the number of seconds per rotation

52 second/65 rotations

52/65

0.8 seconds/1 rotation

0.8 seconds per rotation

Now let us multiply 0.8 by 200 to get our answer

0.8 * 200

160

It takes 160 seconds to do 200 rotations

Answer:

160 seconds

Step-by-step explanation:

We have 65 rotations in 52 seconds, let's represent it like this:

[tex]\frac{52 seconds}{65 rotations}[/tex]

Now, let's multiply this by 200 rotations, and cancel out the rotations on the bottom:

[tex]\frac{52 seconds}{65 rotations} * 200 rotations[/tex]

See how there is rotations on both the top and bottom? This cancels both of them and leaves seconds!

Multiply the above equation and we get:

160 seconds or 2 minutes 40 seconds.

Answer:

y=3x+12

Step-by-step explanation:

Use this formula: y-y1=m(x-x1)
(y-Your y point=slope(x-Your x point)

Point= (-2, 6), Slope= 3

(Anything negative, you add. Anything positive, you subtract.)

Plug in your values: y-6=3(x+2)
distribute: y-6=3x+6
Add six to both sides of the equation:y-6(+6)=3x+6(+6)
We get our answer: y=3x+12

Given that

Samantha has a bag of 5 different colored marbles.

She randomly picks a marble from the bag, records the color, and returns it to the bag before picking another marble.

We have to determine

What is the probability that she picks a blue marble three times in a row?

According to the question

Samantha has a bag of 5 different colored marbles.

She randomly picks a marble from the bag, records the color, and returns it to the bag before picking another marble.

The probability of picking a bag one time is,

Number of bag pack at a time

Total number of bag

=1/5

The probability of picking a bag second time is,

Number of bag pack at a time Total number of bag

=1/5

The probability of picking a bag third time is,

Number of bag pack at a time

Total number of bag

=1/5

031%

Therefore,

The probability that she picks a blue marble three times in a row is,

= 1/5 X 1/5 X 1/5

1 /125

Hence, the probability that she picks a blue marble three times in a row is 1/125.
