The number of termites in a nest in any given month can be represented by the
function f(t) = 4(3)^t where t represents the number of months.

The number of ants in a box can be represented by the function represented by the
table:

Months
0-1-2-3-4
Number 20-45-101-228-513

What is the positive difference in the number of termites and the number of ants in
the fourth year?

Answers

im pretty sure the answer is 189

The positive difference in the number of termites and the number of ants in the fourth month will be 189. Option B is correct.

What is the application of subtraction?

In mathematics, subtraction is defined as the difference between two quantities. The application of subtraction can be used broadly in different applications to find or solve the problems such as finding differences between two quantities and many more.

It is given that, the number of termites in a nest in any given month can be represented by the function [tex]\rm f(t) = 4(3)^t[/tex].

For the fourth month,

f(4) = 4(3)⁴

f(4) = 324

From the table, it is observed that the number of ants in four months is 513.

The positive difference in the number of termites and the number of ants in the fourth month is found as,

=513-324

=189

Thus, the positive difference in the number of termites and the number of ants in the fourth will be 189. Option B is correct.

A science class has 5 girls and 3 boys in the seventh grade and 4 girls and 4 boys in the eighth grade. The teacher randomly selects a seventh grader and an
eighth grader from the class for a competition. What is the probability that the students she selects are both boys?
Write your answer as a fraction in simplest form.

Answers

Answer:

To find the probability of picking two boys, we need to first know how many different ways she can pick the 7th and 8th grader.

There are 12 7th-graders and 8 8th-graders. So the total number of ways she can pick is:

12

×

8

=

96

To get two boys picked, there are 5 boys in the 7th-grade class and 4 in the 8th-grade class, so there are:

5

×

4

=

20

ways

Which gives us the probability of:

1) Hot dogs are sold in packs of 10 and hot dog buns are sold in packs of 8. Tommy wants
to know the least number of packs of hot dogs and buns he needs to buy so that he does not
have any left over.
) Complete the table.

Answers

Answer:

10, 20,30, 40, 50

Step-by-step explanation:

You times them all by 10 for example: 1x10=10 2x10=20 3x10= 30 4x10=40 and 5x10=50.

If we buy four packs of hot dogs and five packs of buns then we don't have any left over.

What is Least common multiple?

The abbreviation LCM stands for "Least Common Multiple." The smallest multiple that two or more numbers share is known as the least common multiple.

For example: Take two integers, 2 and 3.

Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20….

Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30 ….

Therefore, 6 is the least common multiple of 2 and 3.

Given:

Packs          1       2     3      4       5

Hot Dogs   10     20   30   40    50

Bun             8      16     24   32    40

Also, LCM(10, 8)

10= 2 x 5

8= 2 x 2 x 2

So, LCM(10, 8)= 2 x 2 x 2 x 5 = 40

Hence, If we buy four packs of hot dogs and five packs of buns then we don't have any left over.

2x - 19

Step-by-step explanation:

Perimeter = sum of sides

First let's simplify each side

We can simplify each side by using distributive property. Distributive property is where you multiply the number on the outside of the parenthesis by the numbers on the inside of the parenthesis.

2(x + 5)

Distribute by multiplying x and 5 by 2

2 * x = 2x and 2 * 5 = 10

2x + 10

1/2(4x + 8)

Distribute by multiplying 4x and 8 by 1/2

1/2 * 4x = 2x and 1/2 * 8 = 4

2x + 4

-3(2x + 11)

Distribute by multiplying 2x and 11 by -3

-3 * 2x = -6x

-3 * -33

-6x - 33

Finally add all the simplified expressions ( remember that they represent the side lengths of the triangle )

2x + 10 + 2x + 4 - 6x - 33

Combine like terms

2x + 2x - 6x = -2x

10 + 4 - 33 = -19

Perimeter: -2x - 19

What is the equation of a line through point (-12,20) that is perpendicular to the line
with equation y=-6x + 4?

Answers

Answer:      y =  ¹/₆ x + 22.

Step-by-step explanation:

Find the slope of the perpendicular line

When two lines are perpendicular, the product of their slopes is -1. This means that the slopes are negative-reciprocals of each other.

            ⇒  if the slope of one of the lines =  - 6

                 then the slope of the perpendicular line (m) = ¹/₆

Determine the equation

We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:

                              ⇒  y - 20 =  ¹/₆ (x - (-12))

                               ∴  y - 20 = ¹/₆ (x + 12)

We can also write the equation in the slope-intercept form (y=mx+c) like the equation in the question by making y the subject of the equation and expanding the bracket to simplify:

                          since   y - 20 = ¹/₆ (x + 12)

                                      y - 20 =  ¹/₆x + 2

                                              y =  ¹/₆x + 22

                             

∴ the slope-intercept equation of the perpendicular line is y =  ¹/₆ x + 22.
