Hints:
1) This is an arithmetic sequence.
2) The first member of the sequence is 4.
3) The common difference is 6. To each member, we add 6 to get the next.
4) The formula for the nth term of an arith. sequence is as follows:
l=a + (n-1)d, where l is the LAST term, n is the number of terms, d is the common difference, and a is the first term. Write this out. Play with n, increasing (integer) n until this formula predicts numbers close to 576. Do you get exactly 576 for one of these INTEGER n values? If yes, then 576 is a member of the sequence. If no, then it is not.
Graph should represent "miles per gallon" that means the y axis are miles driven with x axis gallons used.
See image attached.
The fuel usage is approximately linear so the graph is a line. The origin of the graph (0,0) corresponds to the starting point in MIami, FL, where 0 gallon have been spent and 0 miles driven. the endpoint corresponds to Atlanta, GA, where 90 gallons have been spent and 660 miles driven. The domain is real numbers in the interval [0,90]. The x intercept is 0, the y intercept is also 0. The range is real numbers in the interval [0,660].
Answer:
Angle A is 40 Degrees
Angle B is 60 Degrees
Step-by-step explanation:
Angle C = 80 Degrees.
Angle A = 1/2 x Angle C ( 1/2 *80)
Angle B = 3/4 x Angle C (3/4 * 80)
Angle A:
80 * 0.5 = 40 (half of 80 since 1/2) = 40 Degrees
Angle B:
80 * 0.75 = 60 (three fourths of 80 since 3/4) = 60 Degrees
Check:
All angles of a triangle equal to 180 Degrees for any Triangle.
Therefore;
Angle A + Angle B + Angle C = 180 Degrees
40 Degrees + 60 Degrees + 80 Degrees = 180 Degrees
180 Degrees = 180 Degrees
So it checks out, so voila! :)
Y=55
Explanation:
If you’re looking to see how 11 and y would match -9 and -45 you would find the unit rate of -9 and -45.
-9/-9=1
-45/-9=5
So if the y is going up by 5’s it would be 55.
Answer:
$ 7.04
Step-by-step explanation:
The price after two reductions means that we have to multiply the initial price by 25% twice. Remember that 25% is equal to 0.25, because the percentage sign refers to a division by 100. Therefore, the final price after two reductions is $7.04.
