Jessica and Raphael are saving up money to buy concert tickets. Jessica has $20 and saves $10 each week. Jessica came up with th

e following equation to figure out how much money she saves any given week: y = 10x + 20 Raphael has $40 and saves $6 each week. Raphael created the table to show how much money her saves any given week. (I will put the table in coordinate pairs because it won't upload so...) (0,40) (1,46) (2,52) (3,58) (4,64) (5,70) (6,76) (7,82) (8,88) After saving money for a certain amount of weeks, Jessica and Raphael will have each saved the same amount of money. How much money will they have saved by then?

Let X = seventh graders

6th graders are twice the number of 7th graders; therefore, 6th graders will be 2X.
The total number of students is 57.

2X + X = 57
3X       = 57
X         = 57 / 3
X         = 19

IF X represents the 7th graders; there are 19 seventh graders present.
Since 6th graders are represented by 2X; Then, 2 * 19 = 38 is the number of 6th graders present.

Add both numbers to check: 19 + 38 = 57.

(05.06 LC) A person drives her own personal vehicle to work two days of the week. Her commute to and from work is 42 miles a day
Inessa05 [86]

Answer:

1.5 gallon per day

Step-by-step explanation:

As given,

Daily miles = 42

Average gasoline used = 28 mil/gallon

Daily use of gasoline = \frac{Daily mile}{Average gasoline}

                                   = \frac{42}{28} = 1.5 gallon /day

∴ we get

she conserve gasoline a day = 1.5 gallon per day

A spherical balloon centered at (2,1,2) starts at 1 cm in diameter and begins growing.The sphere is being inflated at a constant
kirill [66]

Answer:

\frac{1}{12\pi^{2}  } seconds pass

Step-by-step explanation:

V=\frac{4}{3}\pi r^{3} = \frac{4}{3}\pi   (\frac{1}{2} )^{3}=\frac{4}{3}\pi   \frac{1}{8}=\frac{1}{6}\pi cm^{3}

(Volume of the D=1 cm sphere)

Now we have to find out the time needed to reach that volume at the filling rate of 2\pi ^{3} cm^{3} /s

So

\frac{2\pi^{3}  }{1 sec} =\frac{\frac{\pi }{6} }{x}

x=\frac{\frac{\pi }{6} }{2\pi^{3}  } =\frac{1}{12\pi^{2} }sec
