Answer: First solve the parentheses using order of operations. Then add and subtract from left to right.

Demo:

(3 * 11) = 33

Equation now looks like:

63 - 21 + 33

63 - 21 = 42

Equation now looks like:

42 + 33

42 + 33 = 75

The value of this expression is 75.

Lin's teacher uses the box to store her set of cubes with an edge length of one half inch. if the box is completely full, how ma
nlexa [21]

Answer:

448 cubes

Step-by-step explanation:

Volume of cubes fitted in the box will be equal to the cumulative volume of the cubes.

Since, volume of a cube = (Side)³

Side of the cube = \frac{1}{2} inch

Therefore, volume of the cube = (\frac{1}{2})^3=\frac{1}{8} inches

Volume of the storage box = 56 cubic inches

Since, number of cubes fitted in the storage box = \frac{\text{Volume of the storage box}}{\text{Volume of one cube}}

                                                                                 = \frac{56}{\frac{1}{8}}

                                                                                 = 56 × 8

                                                                                 = 448 cubes

Therefore, number of cubes fitted in the storage box = 448

Find the next three terms in the sequence below.
fomenos

Answer: 13/6

Step-by-step explanation:

Based upon the previous sequence.

1.there is a constant decrease of two in the numerator

2. There is a constant increase of one in the denominator

to find the fourth number in the sequence I used One of the numbers from the previous to determine the answer.

17/4 — —> then I followed the pattern and determine what fraction 3 was       .   .                 before it was converted into a whole number.

which would be 15/5 —> Now considering equations that are written like this also mean division, because in this case division is possible the answer would be 3, which would make the whole number 3 instead of 15/3. considering it was an improper fraction.

____________________________________________________________

Now If 15/5 wasn’t converted into 3, The answer to the  sequence would be 13/6. If you follow the pattern like I said before there is a certain amount of increase and decrease so 13/6 will be your answer. The only reason is not a whole number because 13 can’t be divided by six to get a whole number.

Two men are at the grocery store at noon. One walks 0.6 miles east and the other one walks 0.8 miles north. After that they stop
Anettt [7]
The north displacement and the east displacement can be viewed as simply the legs of a right triangle and the distance between them is just the magnitude of the hypotenuse so:

h^2=x^2+y^2, where h is the distance between the two points, x is the easterly distance and y is the northerly distance....

h^2=.8^2+.6^2

h^2=.64+.36

h^2=1

h=1

So they are one mile apart from each other.

What is 160% of 19? What is 0.9% of 54? What is 15% of 376?
mafiozo [28]
160% of 19 is 30.4

Convert 160 into a decimal: 160%/100 = 1.6
Multiply the decimal by 19: 1.6 × 19 = 30.4 <-- our answer.
------

0.9% of 54 is 0.486

Convert 0.9% in a decimal: 0.9%/100 = 0.009
Multiply the decimal by 54: 0.009 × 54 = 0.486 <-- our answer.
-------

15% of 376 is 56.4

Convert the percentage into a decimal: 15%/100 = 0.15
Multiply the decimal by 376: 0.15 × 376 = 56.4 <-- our answer.
