Answer:
$6018.15
Step-by-step explanation:
"is" number always goes on TOP "of" number.
"is" number is 79 1/2%
"of" number is $7570
<em>79 1</em><em>/</em><em>2</em><em> </em><em>%</em><em> </em><em>/</em><em> </em><em>$</em><em>7570</em><em> </em><em>*</em><em> </em><em>100</em><em> </em><em>=</em><em> </em><em>$</em><em>6018.15</em><em> </em>
<em>To</em><em> </em><em>find</em><em> </em><em>out</em><em> </em><em>if</em><em> </em><em>the</em><em> </em><em>answer</em><em> </em><em>is</em><em> </em><em>correct</em><em> </em><em>:</em>
<em>6018.15</em><em> </em><em>/</em><em> </em><em>7570</em><em> </em><em>*</em><em> </em><em>100</em><em> </em><em>=</em><em> </em><em>79.12</em><em>%</em>
Answer:
2. x = 47
3. x = 2
Step-by-step explanation:
These problems involve proportions, or equivalent ratios. You can solve for 'x' in each by using cross-multiplication and division.
2. 28(7) = 4(x + 2)
Distribute = 196 = 4x + 8
Subtract 8 from both sides: 196 - 8 = 4x + 8 - 8 or 188 = 4x
Solve for x: x = 47
3. 2(2x + 7) = 11(3x - 4)
Distribute: 4x + 14 = 33x - 44
Add 44 to both sides: 4x + 14 + 44 = 33x - 44 + 44 or 4x + 58 = 33x
Subtract 4x from both sides: 4x + 58 - 4x = 33x - 4x or 58 = 29x
Solve for x: x = 2
She has 648 shirts.
Work:
Lisa has 42 pineapples. 4 + 2 = 6
Johnny has 6 marbles.
42 + 4 + 2 + 6 = 54
54 + 5 + 4 = 63
63 + 6 + 3 = 72
But 72 is a multiple of 6!
Let's go further:
72 * 6 = 432
Now let's look at the word 'shirt'.
The middle letter is I.
I is the 9th letter of the alphabet.
Remember the number 72?
72*9 = 648
Answer:
24s^2, 54s^2, 96s^2
Step-by-step explanation:
Let s represent the initial side length of the cube. Then the area of each face of the cube is A = 6s^2 (recalling that the area of a square of side length s is s^2).
a) Now suppose we double the side length. The total area of the 6 faces of the cube will now be A = 6(2s)^2, or 24s^2 (a 24 times larger surface area),
b) tripled: A = 6(3s)^2 = 54x^2
c) quadrupled? A = 6(4s)^2 = 96s^2
