Given:
1 bag of potting soil
Required
What part is dirt?
The whole bag of potting soil is represented as 1;
Let P represent Peat Moss and D represented Dirt; Such that
Subtract P from both sides
Substitute for P
Take LCM
<em>Hence, </em><em> or </em><em> of the potting soil is Dirt</em>

Given:
Number of samples,
The samples are 49, 52, 48, 52, 54, 51, 53, 53, 53, 51, 52, 52, 52, 50, 51, 53, 53, 46, 48, 52.
The average number of kernels per row is given as the total sum of all the samples divided by the total number of samples.
Therefore, average number of kernels per row is given as:
Answer:
E, needs more info to be determined
Step-by-step explanation:
We know that Kai takes 30 minutes round-trip to get to his school.
One way is uphill and the other is downhill.
He travels twice as fast downhill than uphill.
This means that uphill accounts for 20 minutes of the round-trip and downhill accounts for 10 minutes of his trip.
However, even with this information, we do not know how far his school is.
In order to figure out how far away his school is, we would need more information about the speed at which Kai is traveling.
Simply knowing that he travels twice as fast downhill is not enough.
This question could only be solved by knowing how many miles Kai travels uphill or downhill in a given time.
Answer:
Step-by-step explanation:
The x intercepts occur when the quadratic is equal to zero.
1.
x^2-7x-18=0 factoring we get
(x-9)(x+2)=0 since multiplying anything by zero is zero the x intercepts occur when
x=-2 and 9
2.
2b^2+17b+21=0
2b^2+14b+3b+21=0
2b(b+7)+3(b+7)=0
(2b+3)(b+7)=0
b=-7 and -1.5
