2. Lin's family has completed 30% of a trip. They have traveled
60 miles. How far is the trip? (Hint: You can use a tape diagram,
Highlight the answer that shows how far Lin's family trip is. (2 points)
Answer:
1. D) 17%
2. 200 miles
Step-by-step explanation:
For the first question we can turn the information into a fraction, with the total number of pieces of fruit in the bowl (12) as the denominator and the number of apples (2) as the numerator.
[tex]\frac{2}{12}[/tex]
Then, divide:
2/12 = 0.17 = 17%
For the second question, we set up a proportion. We know that 60 miles corresponds to 30% and the whole distance of the trip, x, corresponds to 100%
[tex]\frac{60}{x} = \frac{30}{100}[/tex]
Cross multiply and solve:
60 * 100 = 30x
6000 = 30x
200 = x

The lines represented by the equations 20y-24x=-20y and 5y-6x=-5 are
a) perpendicular
b) the same line
c) neither parallel nor perpendicular
d) parallel
Answer:don’t listen to the other guy he’s wrong. The answer is the same line.
Step-by-step explanation:
20y-24x=-20 add 24x to both sides
20y=24x-20
Divide 20 to all
New equation is
Y=5/6x-1
Now let’s solve for 5y-6x=-5
Add 6x to both sides
5y=6x-5
Divide 5 to all
The new equation is
Y=6/5x-1
As you see they have the same equation so the answer is that the lines are the same :) have a good day guys hope this helped <3

Why does x^4 * x^-4 = 1?
Answer:
Step-by-step explanation:
when you have a negative exponent, you are going to have a fraction. Example: 2^4 * 2^-4= 2^4 is 16 2^-4 is 1/16.
You get the 16 but because it was a negative exponent, the 16 goes on the bottom. 16 as a fraction is 16/1.
When you multiply 16/1 and 1/16. It comes up to 16/16 or 1.
Does this help?
Answer:
below
Step-by-step explanation:
We can use the product rule of exponents to solve [ x^y * x^z = x^y+z ].
x^4 * x^-4 = 1
x^4+(-4) = 1
x^0 = 1
1 = 1
Best of Luck!
