Answer: It would be 12 to the power of 3

Step-by-step explanation: You can see there are three 12 so you add a tiny little three on the top of 12 so it could be 12 to the power of 3.

Answer:

12x^3

Step-by-step explanation:

The power (exponent) is however many times the base (12) is multiplied by itself. Do NOT confuse this by 12 x 3.

Answer:

Finding the probability of a single die roll requires little effort.

First, remember that by definition, a prime is an integer with precisely two factors: 1 and the number itself (which is why 1 does not qualify: it has only one factor). The numbers from 6 on down that fit the bill are {2,3,5}. Since there are six sides, your answer is:

P(prime) = 3/6 = 1/2 = 50%

Answer:

9

Step-by-step explanation:

In order to find what needs to be added, you can subtract the number your already have. In this case, subtract twelve from twenty-one.

21 - 12 = 9

To check, we can add nine to 12 and see if it works.

12 + 9 = 21 is correct.

So 9 is our answer.

The number that makes the sum of 21 when added with 12 is 9. Found solving the linear equation x + 12 = 21. Hence, option B is the right choice.

Linear equations are relations between two expressions having their degree less than or equal to 1.

In the question, we are given that the sum of a number and 12 is 21.

We are asked to find the number.

We assume the number to be x.

∴ The sum of a number and 12 is expressed using the expression: x + 12

This expression is equal to 21, which can be represented by the linear equation: x + 12 = 21.

To find x, we solve this linear equation using the given steps:

Equation: x + 12 = 21

Subtract 12 from both sides of the equation: x + 12 - 12 = 21 - 12

∴ x = 9.

∴ The number that makes the sum of 21 when added with 12 is 9. Found solving the linear equation x + 12 = 21. Hence, option B is the right choice.

Step-by-step explanation:

Answer:

A. 30°, 70° and 80°

B. 10cm

Step-by-step explanation:

A. the two triangle have same angles so the angles of triangle 2 are 30°, 70° and 80°

B. the perimeter of triangle, is twice as long as the perimeter of triangle 2 so the perimeter of triangle 2 is 20÷2 = 10 cm

35cm!

4 + 4 = 8

7 + 7 = 14

13 + 8 =  21 (13 + (8 - 1 ) = 20 + 1 = 21)

Step-by-step explanation:

The sine of the other acute angle is 15/17 if the cosine of one acute angle of a right triangle is 8/17.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have a cosine of one acute angle of a right triangle is 8/17.

Let's suppose the angle is α

[tex]\rm Cos\alpha = \frac{8}{17}[/tex]

As we know the cos is the ratio of adjacent to hypotenuse and Sin is the ratio of the opposite to hypotenuse.

Let's suppose the length of the hypotenuse is x units

From the Pythagoras theorem:

[tex]\rm 17^2=x^2+8^2[/tex]

x = 15 units

Now the Sin ratio:

[tex]\rm Sin\alpha = \frac{15}{17}[/tex]

Thus, the sine of the other acute angle is 15/17 if the cosine of one acute angle of a right triangle is 8/17.

Check the picture below.

By taking the average number of eggs for both barns, we will see that the correct option is A.

For a set of N elements {x₁, x₂, ..., xₙ} the mean is given by:

[tex]M = \frac{x_1 + x_2 + ... + x_n}{N}[/tex]

For barn 1, the set is {2, 5, 5, 6}

So the mean is:

M1 = (2 + 5 + 5 + 6)/4 = 4.5

For the barn 2, the set is {3, 6, 8, 9}

So the mean is:

M2 = (3 + 6 + 8 + 9)/4 = 6.5

Now, taking the quantity 100%(M2 - M1)/M1 we get:

100%*(6.5 - 4.5)/4.5 = 44%

So the average in barn 2 is around 50% larger than the average in barn 1. Then the correct option is A.

Step-by-step explanation:

Formula to find the volume of a sphere is :

Volume = [tex]\frac{4}{3}[/tex] π r³

Here,

r ⇒ radius

Given that,

Volume ⇒ 8000 ft³

Let us find the radius of the tank now.

Volume = [tex]\frac{4}{3}[/tex] π r³

8000 =  [tex]\frac{4}{3}[/tex] π r³

8000 =  [tex]\frac{4}{3}[/tex] × 3.14 × r³

8000 × 3 = 4 × 3.14 × r³

24000 = 12.56r³

Divide both sides by 12.56.

1910.822 = r³

∛1910.822 = r

12.40 ft = radius

And now let us find the diameter of the sphere.

d = 2r

d = 2 × 12.40

d = 24.8 ft

The diameter of the tank is 24.80 ft

Step-by-step explanation:

Given-

i.e. The volume of spherical tank = 8,000 ft^3

Now, the formula for finding volume of any spherical figure is-

Therefore, substituting value, we get

[tex]⇢8000 = \frac{4}{3} \pi {r}^{3} [/tex]

[tex]⇢8000 \times \frac{3}{4 } = \frac{22}{7} \pi {r}^{3} [/tex]

Transposing 4/3 to left hand side ,it will become 3/4 . And Here, 8000 will get cancelled by 4 leaving 2000

[tex]⇢2000 \times 3 \times \frac{7}{22} = {r}^{3} [/tex]

Similarly , On performing further calculations, we get. ..

[tex]⇢ \frac{21000}{11} = {r}^{3} [/tex]

[tex]⇢1910.822 = {r}^{3} [/tex]

[tex]⇢ \sqrt[3]{1910.822} = r[/tex]

[tex]⇢ \underline{12.40 = r}[/tex]

Thus, the radius of the tank is 12.40 ft

Now,

The diameter of the tank = 2 × radius

[tex] \: \: \: \: \: \: \: \: \: \: \: \: = 2 \times 12.40[/tex]

[tex] \: \: \: \: \: \: \: \: \: \: \: \: = 24.80[/tex]

•°• The diameter of the tank comes out 24.80 ft

60/100 * 75 & 0.60 * 75

60% can be rewritten as 0.60, and since 60/100=0.60, this expression is correct as well

The other two are incorrect because 0.60/100 would be 0.6%, and 60*75 would mean she is saving 6000%

The correct statements regarding the function are:

2. The period of the function is [tex]2\pi[/tex].

4. The amplitude of the function is 2.5.

5. The midline of the function is y = 1.5.

The amplitude of a function is half the difference between the largest and the smallest value.

In this problem, these values are of 4 and -1, hence the amplitude is:

A = (4 - (-1))/2 = 2.5.

Thus the midline is:

y = -1 + 2.5 = 4 - 1.5 = 2.5.

The period of a function is the distance between it's repetitions. Hence, for this graph, the period is of [tex]2\pi[/tex].
