Volume of the copper block = l*w*h = 10*2*0.5 = 10 cm^3
mass = volume * density = 10 * 8.96 = 89.6 grams Answer
Answer:
10,932,240
Step-by-step explanation:
According to the Naspa World list American english have 16,564 6-letters words. Now about the special characters we have the next list !"#$%&'()*+,-./:;<=>[email protected][\]^_`{|}~ and considering the space as a special character we have a total of 33 special characters. For numbers we have a total of 10 digits.
Then to know how many possibles exists we have to find how many possibles are for the last two characters then.

That is the amount os possibles if always the special character go before de number, but as the number could be before the special character we have to multiply this quantity by 2.
Then we have 16,564 words for the first 6 characters and 660 options for the last two. To know the total amount of possibilities we just need to multiply this numbers, then:

Answer:
°
Step-by-step explanation:
(The sum of angles on a triangle is
°)

(Angles of a straight line sums to
°)

Elimination can be used to find the value of one variable:



Now, the value of
can be found by using substitution:

Answer:

Step-by-step explanation:
To determine the area of the logo you have to calculate the area of the triangle and the square that comform it and then add the four areas.
Area of the square.
To calculate the area of the square you have to calculate the square of one of its sides, following the formula:

Where "a" is the length of one of its side.
The side length of the square is a=7cm, so its area will be:

Area of the triangles.
The three triangles are equal, they have a base equal to the side of the square, i.e. with a length of 7cm, and their height is h=4cm.
To calculate the area of one triangle, you have to multiply its base by its height and divide by 2, following the formula:

The area calculated the correspond to one triangle, since all triangles are congruent, you have to multiply the said area by 3 to determine the area of three figures:

Now that the area of all shape are calculated, you have to add them to determine the area of the logo:

<span>3x + y =3
Y = 2x - 7
substitute </span>Y = 2x - 7 into 3x + y =3
3x + y =3
3x +2x - 7 =3
5x = 10
x = 2
Y = 2x - 7 = 2(2) - 7 = -3
answer
(2, -3)
