Answer:
4.9 units
Step-by-step explanation:
We are dealing with a Right angle triangle, and the c is actually the hypotenuse. We are given the measures of a and b.
a being 4, and b being 3.
We need to use the Pythagorean Theorem to solve this.
we can rewrite this as;
Calculation time
15 + 9 = c
c = 24
Now we find the square root of each equation to determine what is.
4 + 3 = 4.89897948557
Let's round that to the nearest tenth.

A kilogram of silver contains 5.58×10²⁴ atoms.
<h3>How to determine the parameter</h3>
From the question given above, the following data were obtained:
- 1 mole of silver = 107.9 g
- Number of atoms in 1 mole of silver = 6.02×10²³ atoms.
- Number of atoms in a kilogram of silver is unknown
Now, we shall convert 1 kg of silver to grams (g).
This can be obtained as follow:
1 kg = 1000g
Therefore, 1 kg of silver is equivalent to 1000g.
Now, let's determine the number of atoms in 1 kg (i.e 1000 g) of silver as follow:
If 107.9 g of silver contains 6.02×10²³ atoms.
Then, 1000 g of silver will contain:
= (1000 × 6.02×10²³) / 107.9
= 5.58×10²⁴ atoms.
Thus, a kilogram of silver contains 5.58×10²⁴ atoms.

The question is basically asking for the difference between how far ryan lives from the store and how far abby lives from the store.
therefore, to solve the problem, we can just do: distance ryan lives from the store minus distance abby lives from the store.
since ryan is 3.76 kilometers from the store and abby is 1.67 kilometers from the store, the answer is:
3.76 - 1.67 = 2.09 kilometers.
The answer to this problem would be D The expression has a value that is 5 times as much as 2 plus 13.
The answer to 2+13x5 is 75!
Answer: AAS
Step-by-step explanation:
Given: In ΔABC and ΔDEF
∠B≅∠E [right angle]
∠A≅∠D
As there is two angles and one non included side of ΔABC is congruent the two corresponding angles and one non- included side of ΔDEF, therefore, by AAS congruence rule.
ΔABC ≅ΔDEF
AAS congruence postulate :- Triangles are congruent if two pairs of corresponding angles and a pair of opposite sides are equal in both triangles.
