Step-by-step explanation:

The Dylan sister Jane received 1/5 marbles, which is a part of 25 if the Dylan has a total of 25 marbles.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

The total number of marbles Dylan has = 25

The total number of marbles Dylan gave to his sister = 5

If we choose one marble out of 25 = 1/25

If we choose 5 marbles = 5(1/25) = 1/5

Thus, the Dylan sister Jane received 1/5 marbles, which is a part of 25 if the Dylan has a total of 25 marbles.

Answer:

140cm

Step-by-step explanation:

We first have to change 2.4 meters into centimeters. And the formula for that is (x)m = (x)cm x 100.

So 2.4 x 100 = (x)m. We can solve this by moving the "." two times to the right and we will get 2.4m = 240cm.

The next step is to divide it by twelve because Billy wants to share it with 12 friends. 240cm/12 = 20cm per person.

Then we have to multiply 20 with 7 to see how many centimeters 7 friends would get.

20*7 = 140. So the answer is 140cm.

1/3 = 4/12

1/4 = 3/12

Add the fraction's numerators

4 + 3 = 7

Subtract by 1 whole

7/12 - 12/12 = 5/12

Thus, your answer is 5/12

Answer:

5/12

Step-by-step explanation:

to give the fractions the same denominator, find their gcm

3 * 4 = 12

therefore multiply 1/3 by 4/4 to get 4/12

multiply 1/4 by 3/3 to get 3/12

3/12 + 4/12 = 7/12

to find the remainder subtract

12/12 - 7/12 = 5/12

Answer:

Step-by-step explanation:

let C' be the bigger circle

and C be the smaller circle and r its radius.

Area(C') = π × (9² -  r²)

Area(C) = π × r²

Area(shaded region) = area(C') - area(C)

                                  = π × (9² -  r²)

the statement “the area of the shaded region is twice that of the smaller circle ” means  π × (9² -  r²) = 2 × π × r²

Now, let’s solve the equation:

π × (9² -  r²) = 2 × π × r²

⇔ π × (9² -  r² - 2r²) = 0

⇔ π × (81 -  3r²) = 0

⇔ 81 -  3r² = 0

⇔ 81 = 3r²

⇔ r² = 27

⇔ r = √27

⇔ r = 3√3

Answer:

6.32

Step-by-step explanation:

Area of bigger circle = π(9)² = 81π cm²

Area of smaller circle = π(9)²/2 = 81π/2 = 40.5πcm²

Area scale factor = (Linear Scale factor)²

81π/40.5π = 9²/x² {cancel the π}

81/40.5 = 81/x² (cross multiplication)

81x² = 40.5 × 81

√x² = √40.5 (square root both sides)

x = 6.32

Based on the calculations, the function which best models the data in the graph is y = 10.1x + 101.

Mathematically, the equation of a line in standard form is given by this formula:

y - y₁ = m(x - x₁)

Where:

In order to determine the function which best models the data in the graph shown in the image attached below, we would calculate the slope of the data by using this formula:

[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}\\\\Slope = \frac{202\;-\;101}{10\;-\;0}\\\\Slope = \frac{101}{10}[/tex]

Slope = 10.1.

For the function, we have:

y - y₁ = m(x - x₁)

y = 10.1(x - 0) + 101

y = 10.1x + 101.

Answer:

Step-by-step explanation:

Each plane has a starting altitude and a fixed rate of climb. Its altitude at some time t will be the sum of the starting altitude and t times the rate of climb.

__

  altitude = starting altitude + t × rate of climb

  a(t) = 4000 +35.25t

  b(t) = 2427 +65.5t

The planes will be at the same altitude at the same time when ...

  a(t) = b(t)

  4000 +35.25t = 2427 +65.5t

  1573 = 30.25t . . . . . . . . . . subtract 2427+35.25t

  52 = t . . . . . . . . . . . . . divide by 30.25

That altitude is ...

  a(52) = 4000 +35.25×52 = 4000 +1833 = 5833

52 seconds will pass before the planes are at the same altitude.

Their altitude then will be 5833 feet.

Answer:

x = 90 degrees.

Step-by-step explanation:

These are all regular octagons and the value of x = 2 * external angle of an octagon.

The sum of external angles of a polygon sum to 360 degrees and in the case of an octagon each external angle = 360/8 = 45 dgrees,

So angle x = 2*45 = 90 degrees.

Using the probability concept, it is found that the number of desired outcomes that Taylor should use in her calculation is given by:

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, Taylor needs a number greater than 3, which for the dice are 4, 5 and 6, that is, 3 desired outcomes, hence option A is correct.

The area of the shape shown in the image which is in the shape of kite figure is 168 squared centimeters.

The area of the kite figure is half of the product of its diagonals. Area of kite figure can be find out using the following formula.

[tex]A=\dfrac{pq}{2}[/tex]

Here, p and q are the diagonals of the kite.

The length of the first diagonal of the kite figure is,

p=6+15
