A rectangle with a perimeter of 78 millimeters has a length and width in a ratio of 9:4. What are the length and width?

Answers

Answer:

Step-by-step explanation:

Let the length be 9x, then the width is 4x

perimeter = 2(9x + 4x) = 2(13x) = 26x = 78, so x = 78/26 = 3

So

the length = 9x = 9(3) = 27 mm

the width = 4x = 4*3 = 12 mm.

Answer:

The interval of decrease is 0 ≤ x ≤ 1.25

Step-by-step explanation:

First, we have to find the point where it changes from increasing to decreasing or decreasing to increasing.

The graph shows that there is a decrease before 1.25 h, and it increases after 1.25 h also.

We can further prove that 1.25 is the point of change when we enter 1.25 in place of t in the given equation

d(1.25) = 40|1.25 - 1.25| = 0

We see that the graph is decreasing before 1.25, so the interval will have to end at 1.25.

We also see that there is no increase before 1.25, so we can make the interval begin at 0

A and B are mutually exclusive events. P(A) = 0.40 and P(B) = 0.30. What is
PA or B)?
A. 0.75
B. 0.22
C. 0.12
D. 0.70

Answers

By mutually exclusive, it means that there are no overlaps between the two events. This means that the probability of the P(A U B) or P(A or B) is simply the sum of the two probabilities.

P(A or B) = 0.40+0.30=0.70

Therefore the answer would be D 0.70

I hope this helped and if you have any more questions to this element please ask!

The value of P(A or B) with A and B are mutually exclusive events is 0.70. Therefore, option D is the correct answer.

What are mutually exclusive events?

Mutually exclusive is a statistical term describing two or more events that cannot happen simultaneously. It is commonly used to describe a situation where the occurrence of one outcome supersedes the other.

Give that, P(A)=0.40 and P(B)=0.30.

We know that, P(A or B) = P(A)+P(B)

= 0.40+0.30

= 0.70

Therefore, option D is the correct answer.

Write a polynomial of degree 3 whose only roots are x=2 and x=2/5. Is there another polynomial of degree 3 that has the same roots?

Answers

Answer:

Step-by-step explanation:

(x - 2)² (x - 2/5) = 0

5(x - 2)² (x - 2/5) = 0

(x - 2)² * 5(x - 2/5) = 0

(x - 2)² (5x - 2) = 0

(x² - 4x + 4)(5x - 2) = 0

5x³ - 20x² + 20x - 2x² + 8x - 8 = 0

5x³ - 22x² + 28x - 8 = 0

Another possible polynomial is

(x - 2) (x - 2/5)² = 0

Explanation : You have to pick a number between 46 - 53 since the number can't be GREATER than 55 for example the answer can't be 60, because it is TOO great a number. However it can't greater than 45, so it can't 35 because it is TOO less of a number, so 46 - 53 are the only options. I hope this helped.

PLEASE HELP!! Multiple Choice 1. Calculate the slant height for the given cone. Round to the nearest tenth (11 Diameter = 8 cm Height = 9 cm O 10.2 cm O 11.4 cm 09.8 cm O 12.0 cm​

Answers

Answer: 9.8 cm

==============================================

Explanation:

Refer to the figure below.

The cone has a circle at the base which has a diameter of 8 cm. This cuts in half to 4 cm, and that's the radius. This forms the horizontal leg of the right triangle highlighted in red.

The vertical leg of the triangle is the height of the cone (9 cm).

---------

Use the pythagorean theorem to find the hypotenuse of the triangle, which is exactly the slant height.

a^2 + b^2 = c^2

4^2 + 9^2 = c^2

16 + 81 = c^2

97 = c^2

c^2 = 97

c = sqrt(97)

c = 9.84886

When rounding to one decimal place, we get 9.8 cm which is the final answer.

What is the equation of a parabola with focus of (5,3) and directrix y=-3

Which choice best shows the Distributive Property? O 6 6+ (10 x 7) = (6 x 10] +7 1 x 6 = 6 None of these answers show the Distributive Property. O 6x (10 + 7) = (6 x 10) + (6 x 7) 6 0 6x 10 = 10 x 6​

Answers

Answer:

6 (10 + 7) = (6 x 10) + (6 x 7)

Step-by-step explanation:

Assuming the answer choices are like this:

6 + (10 x 7) = (6 x 10) + 71 x 6 = 66 (10 + 7) = (6 x 10) + (6 x 7) 6 x 10 = 10 x 6None of these

Distributive Property is the act of taking one number or variable and multiplying it into a set interval. We always distribute before anything else in the equation (PEMDAS) For example:

4 (3 - 5)

The act of distribution is multiplying the 4 by all variables inside the following parenthesis. This act would make the equation turn into this:

4 (3 - 5) → (4 x 3) - (4 x 5) → (12 - 20) → -6

This means out of the option choices the only feasible answer would be:

6 (10 + 7) = (6 x 10) + (6 x 7)

You throw two dice. What is the probability of rolling a 2 on at least one of the dice?

I'll give brainliest to correct answer. Please explain why

Answers

Answer:

0,027

Step-by-step explanation:

Rolling two fair dice more than doubles the difficulty of calculating probabilities. This is because rolling one die is independent of rolling a second one. One roll has no effect on the other. When dealing with independent events we use the multiplication rule. The use of a tree diagram demonstrates that there are 6 x 6 = 36 possible outcomes from rolling two dice.

Answer:

11/36

Step-by-step explanation:

There are 36 possible outcomes from rolling 2 dice because the first die has 6 possible outcomes and so does the second.

If the first dice is a 2, the second die can be from 1 to 6. So, there are 6 ways that one dice can show a 2. Since it can happen to both die, you double it to be 12.

But, we have counted the roll of 2,2 twice. So we minus 1 possibility.

Thus, there are 11 ways to roll at least one 2 and 36 possibilities.
