now you may count the number line and find that you find 6 units, BUT you need to check the values. You can simply do an equation 4 - - 8 = 12 or you can do 6 *2 which is 12.

The  radius of the new sphere of dough is 5.3368

In the given statement is :

Two spherical pieces of cookie dough have radii of 3 centimeters and 5 centimeters, respectively. The pieces are combined to form one large spherical piece of dough.

To find the approximate radius of the new sphere of dough

V 1 = 4/2 · 3³ π = 108/3 π

V 2 = 4/3 · 5³ π = 500/3 π

The new sphere:  V = V 1 + V 2 = 608/3 π

4/3 r³ π = 608/3 π  / : π/3

4 r³ = 608

r³ = 608 : 4 = 152

r = ∛152

r = 5.3368 cm

Hence, The  radius of the new sphere of dough is 5.3368

Step-by-step explanation:

Let us start with Frodo's breakfast. He starts eating a quarter of the porridge. Let us say the porridge is 100 spoons, to make dividing easier. After Frodo we have [tex]\frac{3}{4}[/tex] left of the original bowl; we are left with 75 spoons.

100 - [tex]\frac{1}{4}[/tex] = 100 - 25 = 75

Next, comes Sam's breakfast. He eats 75 - [tex]\frac{1}{4}[/tex] = 75 - 18.75 = 56.25 spoons left.

Next, we have Pippin's breakfast. He eats 56.25 - [tex]\frac{1}{4}[/tex] = 42.1875 spoons.

Lastly, we have Merry's breakfast. He eats 42.1875 - [tex]\frac{1}{4}[/tex] = 31.640625 spoons.

Now, we know we have 31.640625 spoons left. However, we need to know what fraction this is out of the original porridge bowl. So, we do:

31.640625 * 100 = 3164.0625 * 1 = 3164.0625

3164.0625% of the bowl remaining!

What a yummy breakfast!

Image result for Use the Hypotenuse Theorem

The Pythagoras theorem, also known as the Pythagorean theorem, states that the square of the length of the hypotenuse is equal to the sum of squares of the lengths of other two sides of the right-angled triangle. Or, the sum of the squares of the two legs of a right triangle is equal to the square of its hypotenuse.

Step-by-step explanation:

The probability of the spinner's point landing on green is 22.23%.

A pie is a kind of chart that displays data in the form of a circular graph.

We understand that the total value of the pie is always 100%. It is also understood that a circle does have a circumference of 360°. As an outcome, the total of all data points equals 360°. There appear to be mainly two pie chart formulas based on these:

When a circle is completely rotated, it forms a 360-degree angle in the center.

At the center of the circle, a complete rotation yields 360 degrees.

The total percentage of all colors is 100%.

Divide a value of green by 3.6 since 360 degrees / 100% = 3.6.

The total percentage of green displayed by the spinner's pointer is 80%.

P (probability of the cursor landing on green) = 80/3.6

Probability P (cursor landing on green) = 22.222... = 22.23 (approx.)

As a result, the probability which the pointer will land on the green is 22.23%.

The probability that the coin lands heads up and the number rolled is a 6 is 1/12.

Given that a die is rolled and a coin is tossed.

We have to find the probability that the coin lands heads up and the number rolled is a 6.

Probability of getting heads in tossing a coin = 1/2

Probability of getting 6 in rolling a die = 1/6

The event of tossing a coin and rolling die are independent.

Hence,

Probability that the coin lands heads up and the number rolled is a 6 =

The coordinates of the point P is P(x, y) = (- 1, - 10 / 7). (Correct choice: B)

In this problem we find the coordinates of two points on Cartesian plane, of which we must determine the location of a third point by using a formula based on a weight average-like formula:

P(x, y) = (4 / 7) · A(x, y) + (3 / 7) · B(x, y)

P(x, y) = (4 / 7) · (- 4, 2) + (3 / 7) · (3, - 6)

P(x, y) = (- 16 / 7, 8 / 7) + (9 / 7, - 18 / 7)

P(x, y) = (- 7 / 7, - 10 / 7)

P(x, y) = (- 1, - 10 / 7)

June is 9 / 8 times as old as Tomasso in the question.

The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

Given that Ferrera is 3/4 as old as June, and Tomasso is 1. 1/2 times as old as Ferrera.

The number of the times will be calculated as below:-

F = ( 3 /  4) J

T = 1 ( 1 / 2 ) F

T = ( 3 / 2 )F

Put the value of F in the second equation.

T = ( 3 /  2) ( 3 / 4 )J

T = ( 9 / 8)J

Therefore, June is 9 / 8 times as old as Tomasso in the question.

Answer:

y = 8

Step-by-step explanation:

x = 4 is the equation of a vertical line parallel to the y- axis.

A perpendicular line will be a horizontal line with equation

y = c ( where c is the value of the y- coordinates the line passes through )

the line passes through (- 9, 8 ) with y- coordinate 8 , then

y = 8 ← equation of perpendicular line

5 is the correct scale factor

This is because there are 5 little segments that go from C to the larger point in the top right corner. We need 5 pieces of segment CB to get segment CB' where B' is that top right corner point.

Put another way: If the distance from C to B is 1 unit, then the distance from C to B' is 5 units. This shows the distance has multiplied by 5, and that's the scale factor.

The value of x² values that separate the middle 80 % from the rest of the distribution is

With alpha  and  degrees of freedom χ²= 12.443

And with alpha  and  degrees of freedom χ²= 28.412

Chi - Square Distribution:

The chi square distribution is the continuous distribution, where the degree of freedom is the sample size minus 1, and it is the parameter of the chi-square probability distribution.

Given,

Here we need to find the value of x² values that separate the middle 80 % from the rest of the distribution for 20 degrees of freedom.

Based on the given details,

Degrees of freedom = 20

Middle separate value = 80%

Which is equal to 0.8 in decimal point.

The significance level

=> ∝ = 1 - 0.8

=> ∝  = 0.2

But we need the area of the middle so we divide this significance level with 2

so that we get exactly the middle area .

Dividing

=> 0.2/2= 0.1

So we will have two values for chi square

One with  

=> 0.8 + 0.1 = 0.9 alpha

and

one with

=> 0.1 alpha .

This is because the chi square is right tailed.

Now based on the chi square distribution table,

So with alpha 0.9 and 20 degrees of freedom χ²= 12.443

And with alpha 0.1 and 20 degrees of freedom χ²= 28.412

The lengths 12, 16, 10, 5, and 2 of the sides, AP, DQ, CS, PQ, and QR respectively, using the triangle proportionality theorem, gives the area of trapezoid BRSC as 40 square units.

The triangle proportionality theorem states that a line parallel to a side of a triangle and also intersects the other two sides, it divides the two sides proportionally.

Based on the theorem, where the other two sides are perpendicular, the parallel side divides the two sides equally.

The given parameters are;

The figure represented by ABCD = A parallelogram

The lengths of the sides of the figure are;

AP = 12

DQ = 16

CS = 10

PQ = 5

QR = 2

Required: The area of figure BRSC

Solution;

Given that ABCD is a parallelogram, we have;

AD = BC (definition of a parallelogram)

Using the triangle proportionality theorem, we have;

PQ = RS = 5 (segments bounded by equidistant parallel lines)

DQ - CS = AP - BR = 16 - 10 = 6 (Parallel vertical lines intersected by parallel lines at different heights)

AP - BR = 6

BR = 12 - 6 = 6

The area, A, of trapezoid BRSC is therefore;

A = RS × (BR + CS)/2

Which gives;

A = 5 × (6 + 10)/2 = 40
