Angelina has 5 cakes. She wants to cut them into 2/5 pieces. How many pieces will she be able to cut?​

Answer:

7cm

14cm

dπ or 2r π

14π or 2(7π)

Step-by-step explanation:

Radius = 7cm

Diameter = 7 x 2 = 14cm

Circumference = 2 x π x r = dπ

Circumference Value = 2 x π x 7 = 14π

Answer:

Radius: 7 cm

Diameter: 14 cm

Circumference Formula: c = dπ or c = 2rπ

Circumference Value: c = 14π or c = 2(7π)

Step-by-step explanation:

We are given that the radius of the circle is 7 cm. The diameter will always be twice as large as the radius so that will lead us to 14 cm as the diameter of the circle. The formula is quite simple. There are two different types of formulas for finding the circumference of a circle. If only the diameter is given, then we use the formula c = dπ, where d is for diameter and π is for pi or 3.14159. If only the radius is given, then we use the formula c = 2rπ, where r is for radius and π is for pi or 3.14159. In this case, we are going to use the formula for radius since only the radius is given. Simply plug in the value for radius then multiply the radius to π or 3.14159 and multiply the product by 2 to get the circumference of the circle. If I am wrong, please let me know. I hope this helps! :D

The graph of an inequality in two variables is the set of points that represents all solutions to the inequality.

The boundary line that separates the coordinate plane into two halves by a linear inequality represents the solutions to the inequality in one half. For > and, the border line is solid, and for and, it is dashed.

To determine the equation governing the inequality line, enter your slope and a point into the formula y = mx + B, where "m" denotes the slope, "x, y" denotes a point on the line, and "b" is the y-intercept. By inserting (0, 0), you get 0 = 0 + b, which equals 0.

When you rewrite the equation, you get y = x/2. The linear inequality x - 5 > 3x - 10 is an illustration. Due to the greater than symbol being utilised in this inequality, the LHS is clearly greater than the RHS.

Answer:

the volume of the square pyramid is 2430 cubic cm

Answer:

1296 cm³

Step-by-step explanation:

V = a² x [√s²- (a/2)²] / 3

a = 18 cm

s = 15 cm

V = 18² x [√15²-(18/2)²] / 3 = 18² x [√225-81] / 3

V = 324 x (√144/3) = 1296 cm³

Answer:

15% of 25

Step-by-step explanation:

Given the following questions:

25% of 15
15% of 25

We find the answer by using the formula to calculate percentage for both questions.

Question one:
\(\frac{p\times n}{100}\)
\(\frac{25\times15}{100} =25\times15=375\div100=3.75\)
\(=3.75\)

25% of 15 is 3.75

Question two:
\(\frac{p\times n}{100}\)
\(\frac{15\times 25}{100}=15\times25=375\div100=3.75\)
\(=3.75\)

15% of 25 is 3.75

Finally:
\(3.75=3.75\)

\(15-3.75=11.25\)
\(25-3.75=21.25\)
\(11.25 < 21.25\)

Which means 15% of 25 is "greater than" 25% of 15.

The probability the at least of the people selected from 5 is vaccinated is 0.997.

The binomial distribution is a statistical probability distribution that summarizes the likelihood of a value taking one of two independent values under the specific set of assumptions or assumptions.

Because the five randomly chosen people are independent, the probability that they're all unvaccinated is (0.47)⁵,

The probability that at least one among them 5 has been vaccinated is;

= 1 - (0.47)⁵

= 0.997

Therefore, the probability that at least one of the five people chosen is vaccinated is 0.997.

The different 2-member groups that are possible is 28

From the question, we have

Total number of members, n = 8

Numbers to selection, r = 2

The number of ways of selection could be drawn is calculated using the following combination formula

Total = ⁿCᵣ

Where

n = 8 and r = 2

Substitute the known values in the above equation

Total = ⁸C₂

Apply the combination formula

ⁿCᵣ = n!/(n - r)!r!

So, we have

Total = 8!/(6! * 2!)

Evaluate

Total = 28

Hence, the number of ways is 28

The probability that the average length of a randomly selected bundle of steel rods is greater than 168.58 cm is 0.7486

First, we need to calculate the z-score for the sample mean:

z = (x - μ) / (σ / √n)

z = (168.58 - 169) / (2.2 / √10)

z = -0.67

Next, we need to find the probability that a randomly selected bundle of steel rods will have a mean length greater than 168.58 cm. This is equivalent to finding the area under the standard normal distribution curve to the right of z = -0.67.

Using a standard normal distribution table or calculator, we find that the probability is 0.7486.

The length of o is also 189 cm.

What is length ?

Length is the measurement of the extent of an object or distance between two points in space, usually measured in units such as meters, centimeters, feet, inches, or miles. It is one of the fundamental physical quantities used in mathematical, scientific, and engineering applications.

According to the question:
Based on the given information, we can use the law of sines to find the length of side NO:

sin(78°) / NO = sin(15°) / 49 cm

Multiplying both sides by NO and then dividing by sin(78°), we get:

NO = (sin(78°) * 49 cm) / sin(15°)

Using a calculator, we get:

NO ≈ 189 cm

Therefore, the length of o is also 189 cm (since NO = o). Rounding to the nearest centimeter, we get:

o ≈ 189 cm

Answer: y=1.25

Step-by-step explanation:

First things first you have to find what is in the bracket things (i don’t know what it’s called) So 3 - 7 is -4y but since it’s absolute it’s going to be 4y.

So now you’ve got 4y - 10 = -5. Your going to want to eliminate 10 so, subtract 10 to both sides giving you 4y = -5

Lastly to get y by itself you need to divide it by its self so, 4y divided by 4. Do it to both sides. This gives you…

Answer:

Step-by-step explanation:

James is thinking of 6 miles as the total distance and 1/4 mile as one part of that distance. To find out how many parts of 1/4 mile he would have to walk to cover 6 miles, he needs to divide 6 by 1/4.

To perform this division, we need to remember that dividing by a fraction is the same as multiplying by its reciprocal.

The reciprocal of 1/4 is 4, so to divide 6 by 1/4, we multiply 6 by 4:

6 * 4 = 24

So, the quotient of 6 and 1/4 is 24.

First remember that we have the initial function f(x)=|x| and we make 2 movements to the function in order to obtain g(x), lets's see what are those movements:

As you can see if we subtract -2 from the inside of the absolute value we move graph 2 positions to the right, now lets sum 5 to the function and see what happens

If we sum 5 to the function from outside the absolute value we move the graph 5 units up.

\( \cos( \alpha ) = \frac{5}{13} \\ \)

\( \tan( \alpha ) = \frac{12}{5} \\ \)

\( \tan( \alpha ) = \frac{ \sin( \alpha ) }{ \cos( \alpha ) } \\ \)

\( \frac{12}{5} = \frac{ \sin( \alpha ) }{ \frac{5}{13} } \\ \)

Multiply sides by 5 / 13

\( \frac{5}{13} \times \frac{12}{5} = \frac{5}{13} \times \frac{ \sin( \alpha ) }{ \frac{5}{13} } \\ \)

\( \frac{5 \times 12}{5 \times 13} = \sin( \alpha ) \\ \)

\( \frac{12}{13} = \sin( \alpha ) \\ \)

\( \sin( \alpha ) = \frac{12}{13} \\ \)
