Answer:

$3\sqrt{10}$ units I THINK

Step-by-step explanation:

using the distance formula, -2 - 1 = -3

-3 x -3 = 9

-5 - 4 = -9 x -9 = 81

81 + 9 = 90

sqrt 90 simplified is $3\sqrt{10}$ .

so im pretty sure that's the answer.

Sarah is making lemonade where she adds 2 parts lemon juice to 3 parts water.

Vladimir79 [104]

Answer: 6 CUP LEMON

2 part lemon +3part water = 5parts of mix

2part lemon = 3 part water so ratios are:

(2lemon/3wateer) = 1, and also (3water/2lemon) = 1

For 112c lemon (3 water/2lemon) = 3*51= 153 parts water

9c water (2 lemon/3water) = 6 cup lemon

What is f×e where e={1,2,13} and f={44,8,2}?

alexandr1967 [171]

Answer:

$f\times e=\{(1,44),(1,8),(1,2),(2,44),(2,8),(2,2),(13,44),(13,8),(13,2)\}$

Step-by-step explanation:

The Cartesian Product of two sets is all <u>pairs</u> in which the first element of each pair comes from the first set, and the second element comes from the second set.

$f\times e=\{(1,44),(1,8),(1,2),(2,44),(2,8),(2,2),(13,44),(13,8),(13,2)\}$

This was built using 1 from the first set paired with each number in the second set, then using 2 from the first set paired with each number in the second set, then 13 from the first set paired with each number in the second set.

Gnom [1K]

Answer:

m<N, m<L, m<M

Step-by-step explanation:

The angle that sees the longest side length has the bigger angle measurement

so the angles would be listed as following :

from smallest to largest :

m<N, m<L, m<M
