Angela is taping 7 boxes for storage. She uses 1 1/2 feet of tape to close each box how much tape will Angela need to tape the b

Mrrafil [7]

Answer:

B. 10 1/2 feet

Step-by-step explanation:

We are told that she taped 7 boxes.

We are also told that she uses 1 1/2 feet of tape to close each box.

Therefore, the length of tape she will need to use for the 7 boxes will be the product of 7 boxes and 1 1/2 feet of tape per box:

L = 1 1/2 * 7 = 3/2 * 7 = 21/2 = 10 1/2 feet.

She will need to use 10 1/2 feet of tape.

3. Identify the subsets of real numbers that apply to /100/5

Alina [70]

Using number sets, it is found that the correct classification of the number is:

C. rational number, integer, whole number, natural number , real number.

Numbers are classified as:

Whole, which is all positive numbers and zero, also called natural.
Integers, which is the set of whole numbers plus negatives.
Rational, which is the set of integer numbers plus terminating or repeating decimals.
Irrational, which are non terminating decimals.
Real, which are the sum of rational and irrational.

In this problem, the number given is:

$\frac{100}{5} = 20$

Which is a whole(natural) number, thus it is also integer, rational and real, and the correct option is C.

The sum of two numbers is -17 and their difference is 41 what are the two numbers?

liberstina [14]

Answer: the two numbers are 7 and -27

Step-by-step explanation:

Let the two numbers be a and b

From the question,

a + b = -27.......eqn 1

a - b = 41............eqn 2

Sum the two equations

2a = 14

Divide both sides by 2

a = 14/2; a = 7

Substitute a = 7 into equation 2

a - b = 41

7 - b = 41

Make b the subject of the equation

-b = 41 -7

-b = 34

b = -34

Check:

a + b = -27, slot the values of a and b

7 + (-34) = -27

7- 34 = -27

I hope this is clear, please mark as brainliest answer

Luba_88 [7]

You have to subtract the 6 first and then divide the rest by 1/8.
34-6=28
28×1/8=224

Dimensional analysis: How many atoms are in a kilogram of silver, if there are 6.02 x 10^23 atoms per mole and silver weighs 107

kondor19780726 [428]

Answer:

5.58×10²⁴ atoms.

Step-by-step explanation:

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 =.?

Next, 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.

Finally, we shall determine the number of atoms in 1 kg (i.e 1000 g) of silver as follow:

107.9 g of silver contains 6.02×10²³ atoms.

Therefore, 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.
