The first step that we must take before attempting to solve the problem is to understand what the problem is asking us to do and what is given to us to help accomplish that goal. Although it does not explicitly state that we must solve for t, this is usually what the problem statement would be asking if we just receive and expression like this. What is given to us to accomplish that goal is the expression 
.
Now that we have completed that step, we can move onto the next part which is actually solving the problem. The next step that we should take when solving for the unknown, in this case t, is to subtract 4.9t from both sides.
<u>Subtract 4.9t from both sides</u>
Now that we got all of the t's to one side, let us isolate t completely and the next step that we should take is to subtract 0.72 from both sides.
<u>Subtract 0.72 from both sides</u>
The final step that we need to take to isolate t would be to divide both sides by 0.7 which would remove the coefficient from the unknown variable t and divide 0.7 from -0.42
<u>Divide both sides by 0.7</u>
Therefore, after fully narrowing down the solution we were able to determine that the solution of the unknown variable or t is equal to -0.6
Answer:
44.7
Step-by-step explanation:
I guessed based on what the side looks like so if it's wrong I"m so so sorry
Answer: 8 m/s
First let’s convert the time to seconds. There are 69 seconds in a minute so 1 minute and 40 seconds is 60 +40 second which totals to 100 seconds
Now to get the speed in meters per second we divide the total meters run by the total seconds
So the speed will be 800m/100s = 8m/s
Hey there!!
In order to solve this question, we take the area as 196 as these are the total number of plants to cover a specific place.
The formation must be in a square formation
area of a square = ( s ) ²
s = side
or the number of plants in a row
s² = 196
s = √196
s = 14
There are 14 plants in each row
Hope my answer helps!
Answer:
4/663
Step-by-step explanation:
Probability is the likelihood or chance that an event will occur.
Probability = Expected outcome/Total outcome
Since we are to draw from a pack of card, the total outcome will be 52
Since there are 4 hearts;
Pr(selecting heart) = 4/52 = 1/13
If a club is then selected without replacement, the total number of card remaining will be 51;
Pr(selecting a heart) = 4/51
probability of drawing a heart and a club in that order = 4/52 * 4/51
probability of drawing a heart and a club in that order = 16/2652
probability of drawing a heart and a club in that order = 4/663
