Need Help Plzzz With Math 20 Point Plzz Help 20 Points No Links Or Imma Report

Answers

Answer 1

Answer:

The answer is C

Explain:

Solve for x in the first equation.

Add 4y to both sides of the equation

3x=12+4y

12y-9x=36

Divide each term by 3 and simplify

X=4+4y/3

12y-9x=36

Replace all occurrences of x with 4+4y/3 in each equation.

-36=36

X=4+4y/3

Since -36=36 is not true, there is no solution

A board game uses a fair six-sided die and a spinner with five equal-sized sections colored dark blue, green, light blue, red, and yellow. Players roll the die and then spin the spinner. Match each probability statement to its correct value. the probability of getting a 6 and any color except a shade of blue the probability of getting a 5 and a shade of blue the probability of getting an even number and a shade of blue the probability of getting at least 3 and any color except a shade of blue the probability of a getting at most 4 and yellow

Answers

The probability of getting a 6 and any color except a shade of blue is 2/15.

The probability of getting a 5 and a shade of blue is 1/30.

The probability of getting an even number and a shade of blue is 1/10.

The probability of getting at least 3 and any color except a shade of blue is 4/15.

The probability of getting at most 4 and yellow is 2/15.

We have,

The probability of getting a 6 and any color except a shade of blue:

This probability involves rolling a 6 on the die and getting any color except a shade of blue on the spinner.

Since the die has six equally likely outcomes and the spinner has four colors that are not shades of blue, the probability is (1/6) x (4/5) = 2/15.

The probability of getting a 5 and a shade of blue:

This probability involves rolling a 5 on the die and getting a shade of blue on the spinner.

Since the die has six equally likely outcomes and the spinner has one shade of blue section, the probability is (1/6) x (1/5) = 1/30.

The probability of getting an even number and a shade of blue:

This probability involves rolling an even number (2, 4, or 6) on the die and getting a shade of blue on the spinner.

Since the die has three even numbers and six equally likely outcomes, and the spinner has one shade of blue section, the probability is (3/6) x (1/5) = 1/10.

The probability of getting at least 3 and any color except a shade of blue:

This probability involves rolling a number greater than or equal to 3 on the die and getting any color except a shade of blue on the spinner.

Since the die has four outcomes (3, 4, 5, or 6) that satisfy this condition, and the spinner has four colors that are not shades of blue, the probability is (4/6) x (4/5) = 4/15.

The probability of getting at most 4 and yellow:

This probability involves rolling a number less than or equal to 4 on the die and getting yellow on the spinner.

Since the die has four outcomes (1, 2, 3, or 4) that satisfy this condition, and the spinner has one yellow section, the probability is (4/6) x (1/5) = 2/15.

Thus,

The probability of getting a 6 and any color except a shade of blue is 2/15.

The probability of getting a 5 and a shade of blue is 1/30.

The probability of getting an even number and a shade of blue is 1/10.

The probability of getting at least 3 and any color except a shade of blue is 4/15.

The probability of getting at most 4 and yellow is 2/15.

The volume of the box is 60 cubic inches. What are
the length, width, and height of the box?

Answers

Answer: The volume is the product of the Length, Width, and Height: V = LWH.

Step-by-step explanation: We are given V = 240 in.3, and H = 6 in., and L = W + 3 in.

Thus 240 in.3 = (W+3 in.)*W*(6 in.) so W(W+3 in.) = 240 in.3 / 6 in. = 40 in.2

Using the distributive property and moving the constant to the left gives:

W2 + (3 in.)W - 40 in.2 = 0

This factors:

(W + 8 in.)(W - 5 in.) = 0

The first factor gives W = -8 in. which is nonsense because it is negative.

The second factor gives a valid answer of W = 5 in.

What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Given that Ariel is emptying the water from a 10 gallon cooler.

The graph shows the water level in the cooler as she empties it

Rate of change is change in water to change in time

(3, 8) and (0, 10) are the points from graph

Rate of change  = 10-8/0-3

=-2/3

The minus sign is showing that is is decreasing

The water level decreases 2 gallons every 3 seconds

Hence, the water level decreases 2 gallons every 3 seconds describes the rate of change shown in the graph.

x=9/4,x=-9/4

Step-by-step explanation:

Step 1: Add 81 to both sides.

16x^2−81+81=0+81

16x^2=81

Step 2: Divide both sides by 16.

16x^2/16 = 81/16

x^2 = 81/16

Step 3: Take square root.

x = ±√81/16

x=2.25,x=−2.25

Convert to fraction form.

It is supposed to be like 2 paragraphs and about the nullification crisis As of right now, according to Oregons Law ...anyone under the age of 16 operating an ATV on public lands is to be supervised by an adult over the age of 18Youth under the age of 16 are required to have on-line safety training and hands-on rider training. While Federal laws state ...to be at least 12 years of age to operate an ATV on state land. When you look at the rates, it shows the only of the fatalities are riders who are 16 and under. That leaves the other to be LEGAL adults. Meaning in places like Oregon who have less riders than states such as Idaho should minimize the legal age down to at least 14. That way both sides would still get what they want. Oregon will have the age higher than Federal laws and Federal will have it lower than what Oregon wants it to be. I do believe that they should nullify this law because quite a bit of Oregon doesnt ride so the fatality rate would stay down. I am bringing up the fatalities because that is the only reason that Oregon's Law still is to be 16 and older. It would be a little different if the was younger riders. I do believe that states should be able nullify certain laws. Many laws vary depending on the person. But people vary from state to state. So each state is different and needs different laws.
