Answer:

618.4 unit^2.

Step-by-step explanation:

We have 6 surfaces  ( 3 pairs of equal area) so it is:

2 * 8.6*10 + 2 * 8.6*12 + 2 * 10*12

=  2 * 86 + 24*8.6 + 2 * 120

solve the inequality 1/2y>5​

Answers

Answer:

y > 10

Step-by-step explanation:

1/2y>5​

Multiply each side by 2

2* 1/2y>5​*2

y > 10

Answer:

y > 10

Step-by-step explanation:

Inequality:

1/2y>5​

We need to isolate the variable y.

Since it is being multiplied by 1/2, we need to multiply by the reciprocal, or opposite, on both sides. The reciprocal of 1/2 is 2. (Check by multiplying both numbers and making sure the product is 1.)

Multiply:

1/2y>5​

x2     x2

y > 10

Therefore, the simplified inequality is y > 10.

"What is the theoretical probability of rolling a prime number on a standard number cube?"

Answers

Answer:

There are three prime numbers and 3 even numbers on a number cube, so the probability of each is 3/6 = 1/2

Step-by-step explanation:

Probability of rolling a prime number on a standard number cube is  [tex]\frac{1}{2}[/tex] or 0.5.

What is theoretical probability?

The theoretical probability is defined as the ratio of the number of favorable outcomes to the number of possible outcomes.

Numbers on a cube are {1, 2, 3, 4, 5, 6}

Total number of favorable outcomes = 6

Number of prime numbers in {1, 2, 3, 4, 5, 6} are {2, 3, 5}.

Number of favorable outcomes = 3

Probability of rolling a prime number on a standard number cube

P = [tex]\frac{Number of favorable outcomes}{Total number of favorable outcomes }[/tex]

P = [tex]\frac{3}{6}[/tex]

P = [tex]\frac{1}{2}[/tex]

Hence, probability of rolling a prime number on a standard number cube is  [tex]\frac{1}{2}[/tex] or 0.5.

In a running competition, a bronze, silver and gold medal must be given to the top three girls and top three boys. If 15 boys and 4 girls are competing, how many different ways could the six medals possibly be given out?

Answers

Answer:

There are a total of possible 1820 results.

Step-by-step explanation:

Since there are two competitions, one for boys and one for girls, and we want all the possible results we will calculate the possible combinations for the boys and multiply them by the possible combinations for the girls. This is shown below:

[tex]Boys = \frac{15!}{3!(15 - 3)!} = \frac{15!}{3!12!} = \frac{15*14*13*12!}{3!12!}\\Boys = \frac{15*14*13}{3*2*1}\\Boys = \frac{15*14*13}{3*2*1}\\Boys = 455[/tex]

[tex]Girls = \frac{4!}{3!*(4 - 3)!}\\Girls = \frac{4*3!}{3!}\\Girls = 4[/tex]

Total number of possible results:

[tex]results = 4*455\\results = 1820[/tex]

What is the length of a radius of the circle represented by the equation

x2 + y2 - 4x - 4y + 4 = 0?


A) 2 units

B) 4 units

C) 8 units

D) 16 units

Answers

Answer:

A) 2 units

Step-by-step explanation:

Given;

x² + y² - 4x - 4y + 4 = 0

Consider general circle equation;

(x - h)² + (y - k)² = r²

where;

(h , k ) is the center of the circle

r is the radius of the circle

x² + y² - 4x - 4y + 4 = 0

subtract 4 from both sides of the equation

x² + y² - 4x - 4y  =  - 4

square half of coefficient of x and y, and add them to both sides of the equation

x² +  - 4x + (-2)² +  y² - 4y + (-2)² = - 4 +  (-2)² +  (-2)²

factorize x and y

(x - 2)² + (y - 2)² = - 4 + 4 + 4

(x - 2)² + (y - 2)² = 4

(x - 2)² + (y - 2)² = 2²

Compare this final equation to general equation of a circle

(x - 2)² + (y - 2)² = 2²  

(x - h)² + (y - k)² = r²

r = 2

Thus, the length of a radius of the circle is 2 units

algebra 1 : ordered pairs kinda dont get it

Answers

Answer:

Option C; 3x - y = -27 and x + 2y = 16

Step-by-step explanation:

1. Let us consider the equation 21x - y = 9. In this case it would be best to keep the equation in this form, in order to find the x and y intercept. Let us first find to y - intercept, for the simplicity ⇒ 21 * ( 0 ) - y = 9 ⇒ y = - 9 when x = 0. Now if we take a look at the first plot of line q, we can see that the x value is -9 rather than the y value, so this equation doesn't match that of line q. This would eliminate the first two options being a possibility.

2. Now let us consider the equation 3x - y = -27. Let us consider the x-intercept in this case. That being said, ⇒ 3x - ( 0 ) = -27 ⇒ 3x = -27 ⇒ x = -9 when y = 0. As we can see, this coordinate matches with one of the coordinates of line q, which might mean that the second equation could match with the equation for line v.

3. To see whether Option 3 is applicable, we must take a look at the 2nd equation x + 2y = 16. Let us calculate the y - intercept here: ( 0 ) + 2y = 16 ⇒ 2y = 16 ⇒ y = 8 when x = 0. Here we can see that this coordinate matches with that of the second coordinate provided as one of the points in line v. That means that ~ Answer: Option C

P(A) = 3/10 P(B) = ? P(A or B) = 4/5

1/2

2/3

1/5

3/10

Answers

Answer:

1/2

Step-by-step explanation:

As they are mutually exclusive P(A and B) = 0 therefore the probability of P(A or B)= P(A) + P(B). Just do 4/5-3/10= 5/10=1/2

The value for P(B) is 1/2.

What is Probability?

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

P(A) = 3/10, P(B) = ?, P(A or B) = 4/5.

As they are mutually exclusive P(A and B) = 0

So, P( A or B)

4/5 = P(A) + P(B)

4/5 = 3/10 + P(B)

P(B) = 4/5 - 3/10

P(B) = 5/10

P(B) = 1/2.

Emery bought three cans of beans I had a total weight of 2.4 pounds each can of beans with the same amount which model correctly illustrates the relationship check all that apply

Answers

Answer:

Figure 2 and 3 are correct

Step-by-step explanation:

This question is incomplete, the figures are attached.

Number of cans of beans bought by Emery = 3

Total weight of cans = 2.4 pounds

Therefore the weight of each can = 2.4/4 = 0.8 pounds

The can be represented by the equation:

y = 0.8x,   where x is the number of cans and y represents the total weight

From the graph of figure 1, weight of each can =  20/16 = 1.25 pounds. This is not correct

From the graph of figure 2, weight of each can =  8/10 = 0.8 pounds. This is correct

From the table of figure 3, weight of each can =  4/5 = 0.8 pounds. This is  correct

From the table of figure 4, weight of each can =  5/4 = 1.25 pounds. This is not correct
