The cat is 12 feet above the ground and the ladder is 9 feet away from the tree because of the mud. How long does the ladder nee

marin [14]

Answer:

15 feet

Step-by-step explanation:

The ladder is the hypotenuse of a right triangle, with the legs being 9 ft and 12 ft long (see the picture).

To solve for the length of the ladder, use the Pythagorean Theorem.

$9^{2} +12^{2} =c^{2} \\c=\sqrt{9^{2} +12^{2}} \\c=\sqrt{81+144} \\c=\sqrt{225} \\c=15$

10._____NaBr+____CaF2 -> ____NaF+____CaBr2

fomenos

Answer:

2NaBr + CaF2 --> 2NaF + CaBr2 gives you:

2Na 2Na

2Br 2F

1Ca 1Ca

2F 2Br

This is balanced.

Step-by-step explanation:

2,1,2,1.

In a balanced chemical equation, the number of particular atoms on the right side of the equation is equal to the number of that atom on the left side of the equation.

As in the left side of the equation, there are 2 F atom and 1 Br. While on the right side there are 1 F and 2 Br. S for the balancing, we will put coefficient to the equation.

And the equation will be:

2NaBr + CaF2 → 2NaF + CaBr2

A = multiples of 5 between 14 and 26

Olenka [21]

Answer:

(A ∪ B) = {15, 17, 19, 20, 21, 23, 25}

Step-by-step explanation:

Multiples of 5:

{0, 5, 10, 15, 20, 25, ...}

So between 14 and 26:

A = {15, 20, 25}

Odd numbers between 14 and 26:

B = {15, 17, 19, 21, 23, 25}

(A ∪ B)

All numbers that are part of at least one of these sets. So

(A ∪ B) = {15, 17, 19, 20, 21, 23, 25}
