Answer:

Irrational.

Step-by-step explanation:

√15 is irrational because although it can be written as a decimal, it cannot be written as a fraction, which is one of the main factors that defines what makes an irrational number.

mr_godi [17]

Answer:

C. JK and LM are congruent

Step-by-step explanation:

Given the coordinates J(-2,8), K(0,8), L(1,0), and M(1,-2), in other to determine whether JK is congruent to LM, we need to determine if the length of side JK and LM are equal i.e JK = LM

To get JK:

We will find the distance between the coordinates J(-2,8), K(0,8) to get the length JK using the formula:

JK =√(x2-x1)²+(y2-y1)²

JK = √(0-(-2))²+(8-8)²

JK = √2²+0²

JK = √4

JK = 2

For the length of LM with coordinate L(1,0), and M(1,-2)

LM = √(1-1)²+(-2-0)²

LM = √0²+(-2)²

LM = √0²+2²

LM = √0+4

LM =√4

LM = 2

Since JK = LM = 2 units, this means that JK and LM are congruent.

BlackZzzverrR [31]

Answer:

270 tomatoes

Step-by-step explanation:

Lets organize the Info

Carrots to Potatoes is 1:2

Potatoes to Tomatoes is 1:3

There are 45 Carrots

So lets input it in the ratio Carrots : Potatoes

45 : 2(45)

45 : 90

There are 90 Potatoes in the garden

Lets input that info to the ratio Potatoes : Tomatoes

90: 3(90)

90 : 270

Summarize:

There are :

45 carrots

90 potatoes

270 tomatoes

If my answer is incorrect, pls correct me!

Find the geometric mean of 5 & 8. Write the exact answer (do NOT round)
yuradex [85]
The geometric mean is defined as the nth root of the product of n numbers.
This means, you multiply all the numbers together
5×8=40
And then you take the nth root of that number. In this case, it's the square root, but if there were more numbers, like three or four, it would be the cube and fourth root, respectively.
√40 = 6.32455532
So, the geometric mean of 5 and 8 is 6.32455532
