Estimate the product of
5
and 4
Then find the product.

Answers

Answer 1

1: Look at the 4, its a lot easier to multiply 5 x 5 rather than 5 x 4, plus if you are estimating, you are going to round either up or down.

2: Multiply 5 x 5 // the answer is 25.

3: Multiply 5 x 4 (the original) // which is 20.

The solution to the inequality expression where the inequality expression is given as  -16<4x+8<24 is -6 < x < 4

What are inequality expressions?

Inequality expressions are mathematical statements that are represented by variables, coefficients and operators where the opposite sides are not equal

How to determine the solution to the inequality expression?

The inequality expression is given as

-16<4x+8<24

Rewrite properly as

-16 < 4x + 8 < 24

Subtract 8 from all parts of the inequality expression

So, we have

-8 -16 < 4x + 8 - 8 < 24 - 8

Evaluate the like terms in all parts of the inequality expression

So, we have

-24 < 4x < 16

Divide through all parts of the inequality expression by 4

So, we have

-6 < x < 4

Hence. the solution to the inequality expression where the inequality expression is given as  -16<4x+8<24 is -6 < x < 4

Jerrica and her brother like to play chess. About a month ago they decided to keep track of how manygames they have won. As of today, Jerrica has won 20 out of the 35 games against her brother.
a. How many games would Jerrica have to win in a row in order to have an 80% winning record?
Justify your answer.

Answers

Jerrica would have to win 40 additional games in a row to have an 80% winning record. This would bring her total wins to 20 + 40 = 60, and her total games played to 35 + 40 = 75.

To determine how many games Jerrica would have to win in a row in order to have an 80% winning record, we need to calculate the number of games she needs to win out of a certain total.

Let's denote the number of games she needs to win in a row as x. If she wins x additional games, her total wins would be 20 + x, and her total games played would be 35 + x.

To have an 80% winning record, she would need to win 80% of the total games played. Mathematically, this can be expressed as:

(20 + x) / (35 + x) = 80 / 100

Cross-multiplying, we get:

100(20 + x) = 80(35 + x)

Expanding and simplifying:

2000 + 100x = 2800 + 80x

Subtracting 80x from both sides:

20x = 800

Dividing by 20:

x = 40

Jerrica would have to win 40 additional games in a row to have an 80% winning record. This would bring her total wins to 20 + 40 = 60, and her total games played to 35 + 40 = 75.

What is a rotation?

In Mathematics and Geometry, a rotation is a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise (anticlockwise) direction.

By applying a rotation of 270° clockwise about the point (1, 2) to the coordinate of the vertices of blue block D, the coordinate the vertices of of its image would be located at the position of the Green: image A.

In this context, we can reasonably infer and logically deduce that Green: image A is the correct transformed shape.

which is the equation of an asymptote of the hyperbola whose equation is (x-2)^2/4 - (y-1)^2/36 =1

Answers

Answer:C

Took the test

Step-by-step explanation:

The  equations of an asymptote of the hyperbola are y = 3x - 5 and y = -3x - 5.

What are the standard form of hyperbola and asymptotes?

The standard form of a hyperbola is:

(x-h)²/a² - (y-k)²/b² = 1

The general equation of the asymptotes for a hyperbola centered at (h,k) with semi-axes a and b is given by:

(y - k) = ± (b/a)(x - h)

To find the equations of the asymptotes of the hyperbola with equation:

(x-2)²/2² - (y-1)²/6² = 1

Plugging in the values, we get:

(y - 1) = ± (6/2)(x - 2)

Simplifying:

y - 1 = ± 3(x - 2)

y = ± 3x - 5

Therefore, the equations of the asymptotes for the given hyperbola are y = 3x - 5 and y = -3x - 5.

10. Prime numbers from 1 to 100 are running a restaurant - PRIME SPOT, near a tourist point. On a winter holiday, 1 and the composite numbers up to 100 enter the restaurant for dinner after their picnic at the same point. The dining hall has tables with seating capacity 15 for each. If they occupy tables without leaving any chair free, how many tables are required? If each prime number attender has to serve equal number of customers, how many customers should each one get to serve? ​

Answers

6 tables are required. Each prime number attender should serve 3 customers each.

The prime numbers between 1 and 100 are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.

All the numbers other than prime numbers are composite numbers.

The composite numbers from 1 to 100 are: 1, 4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100.

Now, as there are 25 primes and 75 composites in the group that visited the restaurant, we can calculate the number of tables required by dividing the number of people by the seating capacity of each table.

Each table has a seating capacity of 15, so the number of tables required will be: Number of tables = (Number of customers)/(Seating capacity of each table)Number of customers = 25 (the number of primes) + 75 (the number of composites) = 100Number of tables = 100/15 = 6 tables

Therefore, 6 tables are required.

Now, as each prime number attender has to serve an equal number of customers, we need to calculate how many customers each one should serve.

Each prime attender has to serve 75/25 = 3 customers each, as there are 75 composites and 25 primes.

Thus, each prime number attender should serve 3 customers each.

The amount of time it would take for the rock to hit the ground is 1.25 seconds.

Given the following data:

Initial velocity = 16 ft/secHeight = 5 ft.

M is the mid point of RS. Use the given information to find the missing values. RM = x + 6 and RS = 5x + 3

Answers

The given information about the midpoint of the line segment RS, and the values of RM = x + 6 and RS = 5x + 3 gives us the missing values as: RM = 9, MS = 9, and RS = 18.

In the question, we are given that M is the midpoint of the line segment RS.

We are asked to find the missing value of MS, using the given information RM = x + 6 and RS = 5x + 3.

Since M is the midpoint of RS, we can say that the segment on the left of M will be equal to the segment to the right of M.

Thus, we get RM = MS.

But, we are given that RM = x + 6.

Thus, we have RM = MS = x + 6.

Also, RM and MS together forms RS.

Thus, we can write that:

RS = RM + MS.

Substituting the known values, we get:

5x + 3 = x + 6 + x + 6,

or, 5x + 3 = 2x + 12,

or, 5x - 2x = 12 - 3,

or, 3x = 9,

or, x = 9/3,

or, x = 3.

Using the value of x = 3, we can get:

RM = x + 6 = 3 + 6 = 9.

MS = x + 6 = 3 + 6 = 9.

RS = 5x + 3 = 5*3 + 3 = 15 + 3 = 18.

Thus, the given information about the midpoint of the line segment RS, and the values of RM = x + 6 and RS = 5x + 3 gives us the missing values as: RM = 9, MS = 9, and RS = 18.
