Broderick needs to solve the formula below for r. Which correctly describes the first step he should take?

Answer:

1/6

Step-by-step explanation:

3 out of 18 marbles are green. 3/18 can be reduced to 1/6 because both 3 and 18 are divisible by 3.

3/3=1

18/3=6

1/6

The probability of picking a green marble is 1/6.

To find the probability of picking a green marble, we need to consider the total number of marbles and the number of green marbles in the jar. The jar contains a total of 18 marbles, and out of these, there are 3 green marbles.

The probability of an event happening is calculated by dividing the number of favorable outcomes (in this case, the number of green marbles) by the total number of possible outcomes (the total number of marbles in the jar).

So, the probability of picking a green marble can be written as:

P(green marble) = Number of green marbles / Total number of marbles

Substituting the values, we get: P(green marble) = 3 / 18

To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 3. Dividing both 3 and 18 by 3, we get: P(green marble) = 1 / 6

Therefore, the probability of picking a green marble from the jar is 1/6. This means that if you randomly pick a marble from the jar, there is a 1 in 6 chance that it will be green.

Answer:

Graph 1 is not proportional

Graph 2 is proportional - y is 2 times x

Step-by-step explanation:

In graph 1, there is no x-y correlation

In graph 2, there is, when x=1, y=6

when x=2, y=12. Therefore, when x=3 y would equal 18.

Answer:

For the company to break even, the number of units sold is 500 units

Step-by-step explanation:

To get this number of units, we simply substitute the value of 0 for p

we have this as;

0 =x^2 -2500

x^2 = 2500

x = √2500

x = 500 (we do not consider the other root of x = -500 since the number of quantities cannot be negative)

Answer:

5 days

Step-by-step explanation:

dogs, combined, eat 80 ounches of food daily

there are 16 ounces in one pound so there are 25x16, or 400 ounces, in a 25-pound bag

400/80 = 5

25-pound bag would last 5 days

One bag of dog food volunteered by Amelia, Which have quantity of 25 pounds  will last for 5 days.

What is ratio?

Ratio is mathematical term, which we use for comparing two or more terms. basically it indicates that how much big or small is number in compared to another.

Given that,

Every day, Amelia puts out 10 ounces of food for each of the 8 dogs.

Dog food comes in 25-pound bags.

And it is know that,

1 pound = 16 ounce;

so by that way it can state that,

Dog food for 25-pound bag will be equal to;

25*16

400 ounce.

Everyday requirement of dog food is 8*10 = 80 ounce/day

Number of days food will  last= Available quantity/Everyday requirement

Number of days food will  last= 400/80

Number of days food will  last= 5 days

Hence, One bag of food will be enough for 5 days.

The table in the exercise can be completed with the next results:

Step-by-step explanation:

As in the exercise Janice is 7 years older than Tam, to obtain the result in the table, you must add 7 to each age in the column x, with this we can make the next formula:

Remember that x is Tam's age, and y is Janice's age, so, you must replace the x variable in each case to obtain the result to y:

When x is 2:

When x is 4:

When x is 6:

When x is 8:

At last, to obtain the graph you can use the formula made: y = x + 7, and you'll obtain a graph like the attached picture, where each time x obtain a unit, the y variable obtain a unit too maintaining the diference of 7.

Answer:

120.105m^2

Step-by-step explanation:

Given data

Diameter of circular bed=  24+3m = 27m

radius= 27/2= 13.5 m

Diameter of side walk = 12

radius= 24= 12 m

Hence the area of the sidewalk is

Area= area of circular bed- area of side walk

Area=πR^2-πr^2

Area=π(R^2-r^2)

Area=π(13.5^2-12^2)

Area= 3.14(182.25-144)

Area= 3.14(38.25)

Area=120.105m^2

Hence the area of the side walk is 120.105m^2

Ok so what I did was base × height for the rectangles because thats the formula for those those I got 70 for both the left and right the left isn't showing but I'm assuming its there its 70 for both because 14 × 5 = 70 then for the bottom is 112 because 14 × 8 = 112 then the two triangles are 12 each because 8 × 3 = 24 then divide by 2 because thats what you do for triangles then I just add all these numbers up so... 70 + 70 + 112 + 12 + 12 = 276
