Sal the sloth takes one hour to travel 7 1/2 feet. If he continues to travel at the same rate, how long will it take him to trav
1 answer:
Answer:
4 hours
Step-by-step explanation:
Since we know he travels at a rate of 1:7.5 all we have to do is divide 7.5 by 30. Do you use proportions? You can set this up as a proportion and the find answer easily.
1
Now we cross product.
7.5 multipled by x =7.5x
1x30=30
so now we have
7.5x=30
Now we have to divide 7.5 on both sides which gives us
x=4

Answer:
x = 26
Step-by-step explanation:
Since the triangle is right, use Pythagoras' identity to find x
x² = 24² + 10² = 576 + 100 = 676
take the square root of both sides
=
, hence
x = 26
Here is your function:
You're looking for f(-1). To get your answer, you have to replace all the x's with -1.
Here is your new equation:
Multiply 2 by -1
<em>Remember:</em>
MULTIPLYING
- Positive(+) times negative(-) is equal to negative
- Positive(+) times positive(+) is equal to positive
- Negative(-) times negative(-) is equal to positive
- Negative(-) times positive(+) is equal to negative
DIVIDING
- Positive(+) divided by positive(+) is equal to positive
- Positive(+) divided by negative(-) is equal to negative
- Negative(-) divided by positive(+) is equal to negative
- Negative(-) divided by negative(-0 is equal to positive
Since you're multiplying a negative number by a positive number, the answer will be negative.
Here is your new equation:
Add -2 and 2:
That means your answer is 0
