Which of the following statements is false?

Answer:

Step-by-step explanation:

The formula of a volume of a sphere:

[tex]V=\dfrac{4}{3}\pi R^3[/tex]

We have V = 36(3.14) cm³ = V = 36π cm³. Substitute:

[tex]\dfrac{4}{3}\pi R^3=36\pi[/tex]      divide both sides by π

[tex]\dfrac{4}{3}R^3=36[/tex]           multiply both sides by 3

[tex]4R^3=108[/tex]            divide both sides by 4

[tex]R^3=27\to R=\sqrt[3]{27}\\\\R=3\ cm[/tex]

The diameter D = 2R.

Therefore D = 2(3 cm) = 6cm

7.32

10 = 73.2

100 = 732

1000 = 7320

0.006

10 = 0.06

100 = 0.6

1000 = 6

The decimal place moves to the right depending on how many zeros the number has.

For example, if you had 0.6 multiplied by 100, you would move 2 decimal places to the right because 100 has two zeros.

5:1, 5/6, or 84%(rounded).

There is one chance of rolling a 2 and since it is against rolling a 2, you have a 5 other numbers you could get.

The probability of rolling an odd number on a six-sided die is 1/2 or 50%, calculated by dividing the 3 odd outcomes (1, 3, and 5) by the total of 6 possible outcomes.

If you roll a single six-sided die, the question asks what is the probability of rolling an odd number. A six-sided die has three odd numbers (1, 3, and 5) and three even numbers (2, 4, and 6). Therefore, the probability of rolling an odd number is calculated by dividing the number of odd outcomes by the total number of possible outcomes.

The formula for probability is Probability = Number of favorable outcomes / Total number of possible outcomes. In this case, there are 3 favorable outcomes (rolling a 1, 3, or 5) out of 6 possible outcomes (since a die has 6 sides). Therefore, the probability is 3/6, which simplifies to 1/2.

So, if you roll a single six-sided die, the probability of rolling an odd number is 1/2 or 50%.

Step-by-step explanation:

2/3=10/15 (divide 15 by 3 to get 5, then multiply both numerator and denominator by 5 to set equivalent)

3/5=9/15

10/15 is greater than 9/15, so during the 1st week there were more boy campers

During the first week of a summer camp, there were more boy campers.

To determine during which week there were more boy campers, we need to compare the fractions of boys in each week. In the first week, 2 out of 3 campers were boys, which can be written as a fraction as 2/3. In the second week, 3 out of 5 campers were boys, which can be written as a fraction as 3/5. To compare these fractions, we need to find a common denominator. In this case, the lowest common denominator is 15, which is the total number of campers each week. Multiplying the numerator and denominator of each fraction by 5 and 3 respectively, we get 10/15 for the first week and 9/15 for the second week. Therefore, during the first week, there were more boy campers.

Answer:

16,21,15

Step-by-step explanation:

The solutions are 16, 21, and 15. The only value that is not a solution is 11 since 11 is less than 15

Inequality expressions are expressions separated by an unequal sign

Given the inequality expression 15 ≤ y

On swapping sides, the inequality sign will change to have y ≥ 15

Based on the table, we need to select yes for values that are greater than or equal to 15 and select no if otherwise

Based on the given value, the solutions are 16, 21, and 15. The only value that is not a solution is 11 since 11 is less than 15

Answer:

50% and 50%, they are both the same!

When breeding a patchwork fish (Bb) with a fish that only has Blue Scales (BB), there is a 50% chance of having fish with red scales (Bb) and a 0% chance of having fish with patchwork scales (bb).

When breeding a patchwork fish (Bb) with a fish that only has Blue Scales (BB), the offspring will have a 50% chance of having red scales (Bb) and a 50% chance of having blue scales (BB). This is because the blue scales are dominant over the red scales, represented by the capital 'B', and the patchwork scales are recessive, represented by the lowercase 'b'.

To calculate the probability of having fish with red scales, we divide the number of offspring with red scales (Bb) by the total number of possible offspring, and then multiply by 100. So the probability is 50%.

To calculate the probability of having fish with patchwork scales, we divide the number of offspring with patchwork scales (bb) by the total number of possible offspring, and then multiply by 100. Since the fish that only has blue scales does not carry the patchwork gene, there will be no offspring with patchwork scales. Therefore, the probability is 0%.

12x-6y+2

Answer:

A. 3 Inches

Step-by-step explanation:

To find the radius of the circle, we need to use the Pythagorean Theorem.

a²+b²=c²

a = r inches

b = AD or 4 inches

Now to get the value of c, we need to consider the measurement of the line AD. The sum of line AD and line DC will be the value of the hypotenuse.

c = r + 2 inches

Now that we have our variables, let's plug them in.

a² + b² = c²

r²+ 4² = (r + 2)²

Now we need to use the FOIL method for r + 2.

r² + 16 = (r + 2)(r + 2)

r² + 16= r² + 2r + 2r + 4

r² + 16 = r² + 4r + 4

Now we can remove r² by subtracting both sides by r², leaving us with:

16 = 4r + 4

Now we subtract 4 from both sides.

4r = 12

Now we divide both sides by 4.

r = 3 inches

Answer:

A. 3 inches

Step-by-step explanation:

Triangle ABC is a right angled triangle

Therefore;

Using the Pythagoras theorem then;

AB² + BC² = AC²

but BC = CD = radius

Hence;

4² + r² = (r+2)²

16 + r² = r² + 4r +4

 16 - 4 = 4r

    12 = 4r

   r = 3

Therefore; the radius of the circle is 3 inches

Answer:

1)  40°

2) 40°

3) 100°  

Step-by-step explanation:

The sum of angels of a triangle is: 180°

The ratio of angles are: 4x,4x,10x

The sum of ratios: 4x + 4x + 10x

=> 18x

Therefore,

=> 18x = 180

=> x = 180/18

=> x = 10

So, required angels are:

The angles of the triangular supports of the wooden table are 40 degrees, 40 degrees, and 100 degrees.

The sum of the angles in any triangle is 180 degrees. Given that the angles are in the ratio 4x : 4x : 10x, we can find the value of x by setting up the equation:

4x + 4x + 10x = 180

Combining like terms, we get:

18x = 180

To find the value of x, we divide both sides of the equation by 18:

x = 180 / 18

x = 10

Now that we have the value of x, we can find the measures of the three angles:

First angle = 4x = 4 * 10 = 40 degrees

Second angle = 4x = 4 * 10 = 40 degrees

Third angle = 10x = 10 * 10 = 100 degrees

 The answer is: [tex]40^\circ, 40^\circ, 100^\circ.[/tex]

Answer:

(x+7)(x-7)

The factors are -7 and 7

Step-by-step explanation:

Given the function x²-49, to find the factors, we will factorise the expressed using the different of two square.

If a and b are two numbers, then based on difference of two square;

a²-b² = (a+b)(a-b)

Applying this to the function in question

x²-49

= x²-7²

= (x+7)(x-7)

The factors can be gotten by equating the function to zero according to factor theorem.

(x+7)(x-7) = 0

x+7 = 0 and x-7 = 0

Answer:

She can chose 2 books from 8 books in 28 different way.

Step-by-step explanation:

In the given scenario the member has to chose 2 books from a group of 8 books. The order of choosing books does not matter. For example if the books are A,B,C,D,E,F,G and H, and the member picks books A and B or books B and A, she is picking up the same books. This means order of selection does not matter here, so this is a problem of combinations.

We have to form combination of 8 books taken 2 at a time i.e. 8C2

The general formula of combination is:

[tex]nCr=\frac{n!}{r!(n-r)!}[/tex]

Using the values of n=8 and r=2, we get:

[tex]8C2=\frac{8!}{2!(8-2)!}=28[/tex]

Answer:

315 in^2

Step-by-step explanation:

Triangles

Area of the two triangular faces.

Area = 1/2 * h * b

h = 7 in

b = 11 in

Area = 1/2 * 7 * 11

Area = 1/2 * 77

Area = 38.5

But there are 2 faces

Area = 38.5 * 2

Area = 77 in^2

Area Left Face

Area left face = height * width

Area left face = 14 * 8

Area left face = 112 in^2

Area Right face

Area Right face = w*h

w = 9

h = 14

Area = w*h

Area right face = 126 in^2

Total Area

Total Area = 126 + 112 + 77

Total Area = 315 in^2
