An equation is written to represent the relationship between the temperature in Alaska during a snow storm, y, as it relates to

Charra [1.4K]

Answer:

the first and fourth quadrants

Step-by-step explanation:

We have that the time found hours is given on the x-axis and that the temperature is represented on the y-axis.

Let's first analyze time:

Time cannot be negative, therefore, the x coordinate cannot be negative therefore, for the x axis, we can use the first and fourth quadrants

Second let's analyze the temperature:

The temperature can be negative, therefore, the coordinate and can be positive or negative therefore, that for the y axis, we can use all four quadrants.

If we combine the two previous conditions, we can deduce that we can only use the first and fourth quadrants to represent the required data.

Marilyn is playing a game where she draws a slip of paper with the words "Rock, Paper, Scissors" written on each slip from a hat

marysya [2.9K]

Answer:

1/6

Step-by-step explanation:

In a game of "Rock, Paper, Scissors", there are three possibilities. The probability that Marilyn will get Paper is given as

1/3

In a coin flip, the probability that it will land on tails is

1/2

Therefore, the probability that she will win if she predicts "Paper" and calls Tails is the product of the individual probabilities:

1/3 * 1/2 = 1/6

The sum of two circles is 80 pi square meters. Find the length of the radius if one of them is twice as long as the other

REY [17]

Answer:

Length of Radius of large circle= 8

Lenght radius of first circle= 2

Step-by-step explanation:

THIS IS THE COMPLETE QUESTION

The sum of the areas of two circles is 80π square meters. Find the length of a radius of each circle if one of them is twice as long as the other.

What is the radius of the larger circle?

Area of a circle can be calculated by Below formula

A = πr^2............eqn(1)

Let ( X) = area of first circle

Y= the area of second circle

Rx= radius of first circle

Ry = radius of second circle

From the question, we know that

[X+ Y] = 80π .......eqn(2)

Substitute the radius formula for the area,

[π(Rx)^2 + π (Ry)^2] = 80π ......eqn(3)

But from the question, Radius of second circle is twice of the second one, then

Ry = 2Rx ..........eqn(4)

If we substitute eqn (4) into eqn(3)

[ π(Rx)^2 + π (2Rx)^2 = 80π

If factorize π out, then cancel it out

π[(Rx)^2 + π (2Rx)^2 = 80π

Then we have

(Rx)^2 + 4(Rx)^2 = 80

5(Rx)^2 = 80

(Rx)^2= 80/5

(Rx)^2= 16

(Rx)= 4

From eqn(4)

Ry = 2Rx

Ry= 2(4)

Ry= 8

Rx= 2 and Ry= 8

Hence, radius of first circle= 2

Lenght Radius of second circle= 8
