Answer:

1r + 3t

to find the answer, all you have to do is simplify both numbers by the highest common factor which is 20.

I just would put 20(r+3t)

What is the least common multiple. Thanks.

o-na [289]

Before we start, find the LCM of 9, 5, and 5, which is 1. The least common multiple for the x is x^3, because it is the smallest exponent. The smallest multiple for y is 0, because the last factor doesn't even have y. For z, it is z^2. So your answer is 1x^3z^2, or just x^3,z^2.

Geometry question for homework.

mars1129 [50]

So remember that the distance formula is $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ .

1.

$\sqrt{(4-4)^2+(-2-(-5))^2}\\ \sqrt{0^2+3^2}\\ \sqrt{0+9}\\ \sqrt{9}\\ 3$

Distance between (4,-5) and (4,-2) is 3 units.

2.

$\sqrt{(1-(-1))^2+(1-4)^2}\\ \sqrt{2^2+(-3)^2}\\ \sqrt{4+9}\\ \sqrt{13}$

Distance between (1,1) and (-1,4) is √13 (or 3.61 rounded to the hundreths) units.

What is the sum of the probability of drawing a green marble and the probability of not drawing a green marble?

andrey2020 [161]

Yo sup??

the answer is 1 because

P(E)+P(E')=1

where E is the event and

E' is the complement of the event

Avery planned a circular garden and path as shown below. The radius of the garden is 4 feet and the path around the garden is 2

Digiron [165]

Answer:

Option C) 113.0 feet squared

Step-by-step explanation:

We are given the following in the question:

Radius of circular garden = 4 feet

Length of path around garden = 2 feet

We have to find the total area of garden and path.

The garden and path together makes a bigger circle with radius

$R = 4 + 2 = 6\text{ Feet}$

Area of garden and path =

$A = \pi R^2$

Putting values, we get,

$A = 3.14\times (6)^2 = 113.04\\A \approx = 113.0\text{ square feet}$

Thus, the correct answer is

Option C) 113.0 feet squared
