Answer:
The car would need 12 gallons of gas to go 360 miles
Step-by-step explanation:
360÷30=12
ANSWER
EXPLANATION
The given sequence is
3,-5,-13,.....-229.
The first term of this sequence is
a_1=3
There is a common difference of
The last term of this sequence is -229.
The nth term of this sequence is given by:
We use the last term to determine the number of terms in the sequence.
Divide through by -8;
Hence there are thirty terms in the sequence.
The sum of the first n terms is given by:
The sum of the first 30 terms is given by:
Probalbity is (desired outcomes)/(total possible outcomes)
total possible=200
desired outcomes=4 tickest (he wants his tickets to be chosen)
prob=4/200=2/100=1/50
probablity is 1/50 or 0.02
Answer:
3 quarts
Step-by-step explanation:
First, find how many quarts of antifreeze is in the mixture.
0.4 x 6 = 2.4
Now, make it into a fraction by putting the antifreeze amount over the rest so:
2.4/6
Now add + a at the end of the numerator and bottom to make:
2.4 + a/ 6 + a.
Now, turn the percentage you want to strengthen or weaken the mixture into a percentage. So, 3/5.
Now, make it an expression by adding = 3/5 at the end of the equation.
2.4 + a/ 6 + a = 3/5
Now, use cross multiplication.
12 + 5a = 18 + 3a
Now, solve the equation.
12 + 5a = 18 + 3a
-3a. -3a
12 + 2a = 18
-12. -12
2a = 6
/2. /2
a = 3.
Therefore, the answer is 3 quarts.
