Answer:
14 lb and 13 oz
Step-by-step explanation:
4 lb 15 oz <u>and </u>twice as much, in total?
1 lb = 16 oz
3(4 lb) and 3(15 oz)
12 and 45 oz = 2 lb and 13 oz
12 lb + 2 lb and 13 oz = <em><u>14 lb and 13 oz</u></em>
Answer:
Melba works more
Step-by-step explanation:
We need to compare with the same units
Lets convert hours to minutes
1 hour = 60 minutes
8 hours* 60 minutes/1hour = 480 minutes
Keith works 480 minutes
Melba works 2250 minutes
Melba works more
Answer:
no, it cannot
Step-by-step explanation:
a difference of square is: a² - b² = (a - b)(a + b)
looking at the expression (5z+3)(-5z-3), we see that it does not fit the criteria of the breakdown of a perfect square, as (-5z-3) has a negative <em>a</em> term (-5z)
if we FOILed (5z+3)(-5z-3) out, we would get:
-25z² - 30z - 9, which is not a difference of squares

Answer:
12.0 cm
Step-by-step explanation:
The Pythagorean theorem applies:
(12 cm)² +b² = (17 cm)²
b² = (289 -144) cm² = 145 cm²
b = √145 cm ≈ 12.04 cm
b ≈ 12.0 cm . . . . rounded to 1 decimal place
<span>For this case we have the following functions transformation:
Vertical expansions:
To graph y = a * f (x)
If a> 1, the graph of y = f (x) is expanded vertically by a factor a.
f1 (x) = (3x) ^ 2
Horizontal translations
Suppose that h> 0
To graph y = f (x-h), move the graph of h units to the right.
f2 (x) = (3x-6) ^ 2
Vertical translations
Suppose that k> 0
To graph y = f (x) + k, move the graph of k units up.
g (x) = (3x-6) ^ 2 + 3
Answer:
expanded horizontally by a factor of 3, horizontal shift rith 6, vertical shift up 3</span>
