2 of them is blue because since there is 16 marbles you multiply 1/8 by 2 and 2/16 so 2 marbles are blue
Answer:
24 spaniels
Step-by-step explanation:
4 many spaniels as retriever means that if you put the dogs in the correct order, every 5 animals you will have one retriever and 4 spaniels, then one retriever and four more spaniels. That is, there are groups of 5 dogs with that ratio. If there are 30 dogs, you can make 6 of these groups. It means that you have 24 spaniels and 6 retrievers.
Answer:
b 1970s
Step-by-step explanation:
15(1.03)^x > 25
(1.03)x > 25/15
x ln 1.03 > ln (25/15)
x > 17.28
So the required year will be 2018
Answer:

Step-by-step explanation:
We want the equation of a line that is parallel to
which also passes through (-7, 1).
Since the new line is parallel, it must have the same slope as the original line.
The slope of the original line is 6.
Hence, the slope of our new line must also be 6.
We know that the slope is 6.
And it passes through the point (-7, 1).
So, we can use the point-slope form:

Where m is the slope and (x₁, y₁) is a point.
Substitute:

Simplify:

Distribute:

Add 1 to both sides. Hence, our equation is:
