Answer:
$320
Step-by-step explanation:
Given parameters:
Cost of attending the 2-year technical college = $3200;
His parents intend to give him half the cost;
Half the cost = [tex]\frac{1}{2}[/tex] x $3200 = $1600
The remaining cost = $3200 - $1600 = $1600
Sam has 5yrs to work every summer;
He must save: [tex]\frac{1600}{5}[/tex] = $320 every summer for the next five years to afford his first year tuition
x+y =783
10x+7y=6459
9514 1404 393
Answer:
(x, y) = (326, 457)
Step-by-step explanation:
Use the first equation to make an expression for y that can be substituted into the second.
y = 783 -x
10x +7(783 -x) = 6459
3x = 978 . . . . . . . . . . . . subtract 7(783) = 5481
x = 326 . . . . . . . . . . . . . divide by 3
y = 783 -326 = 457
The solution is (x, y) = (326, 457).

The spinner in a game based on chance has 25 equal sectors. The prize is worth $50, and the cost to play is $2.50. A player wins if the arrow lands on the sector he or she chose.
Which table shows the correct outcomes for a player who plays the game one time?
Answer:
________________ WIN _____ LOSE
Outcome(x) ______ $47.50 ____ - $2.50
PROBABILITY P(x) _____ __________
Step-by-step explanation:
Given that :
The cost of play = $2.50
The winning price = $50
Hence, if a player emerges victorious or wins; the net amount won is :
Winning price - cost of play
$50 - $2.50 = $47.50
If the player loses :
Then he wins $0
Net amount lost equals :
Amount won - cost of play
$0 - $2.50 = - $2.50
________________ WIN _____ LOSE
Outcome(x) ______ $47.50 ____ - $2.50
PROBABILITY P(x)
Answer:
Win Lose
47.50 -2.50
Step-by-step explanation:
Got it right on the test.

Write an equation in slope-intercept
form to represent the line
perpendicular to 6y = 9 - x with
y-intercept 2
O y = -6x + 2
O y = 2x + 9
Answer:
A, y= -6x + 2
Step-by-step explanation:
1. Put the equation into slope intercept form
6y = 9 - x
y= -1/6x + 9/6
The slope of equation 1 is -1/6
2. A perpendicular line is the inverse slope of our firsy equation. (-1/6)^-1 = -6.
3. The y intercept of a line in slope intercept form is the b value in the equation as written:
y=mx+b
Therefore, if m=-6 and b=2, our equation is
y= -6x + 2

The edge length of a cube is changing at a rate of 10 in/sec. At what rate is the cube's volume changing when the edge length is 3 inches?
Given:
The edge length of a cube is changing at a rate of 10 in/sec.
To find:
The rate by which cube's volume changing when the edge length is 3 inches.
Solution:
We have,
[tex]\dfrac{da}{dt}=10\text{ in/sec}[/tex]
We know that, volume of cube is
[tex]V=a^3[/tex]
Differentiate with respect to t.
[tex]\dfrac{dV}{dt}=3a^2\dfrac{da}{dt}[/tex]
Substituting [tex]\dfrac{da}{dt}=10[/tex] and a=3, we get
[tex]\dfrac{dV}{dt}_{a=3}=3(3)^2(10)[/tex]
[tex]\dfrac{dV}{dt}_{a=3}=3(9)(10)[/tex]
[tex]\dfrac{dV}{dt}_{a=3}=270[/tex]
Therefore, the volume increased by 270 cubic inches per sec.

Define a variable, write an inequality, and solve the problem : Four less than nine times a number is greater than eleven more than two times the same number.
Answer:
x > 15/7
Step-by-step explanation:
four less than nine times a number:
9x - 4
Eleven more than two times the same number:
2x + 11
Thus:
9x - 4 > 2x + 11
7x > 15
x > 15/7

You start at (2, 5). You move left 5 units and right 8 units. Where do you end?
Answer:
(5,5)
Step-by-step explanation:
left 5 is -5 and right 8 is +8.
-5+8=3
2+3=5
When talking about left and right, you change the x-coordinate, when up and down, y-coordinate.
Overall, (5,5)
Answer:
5,5
Step-by-step explanation:
since we are not changing the height of the point and just moving side to side, the y intercept does not change. Once you move 5 units to the left, your new point is -3,5 but then when you move 8 to the right it switches to positive again and the new point is 5,5

I need help figuring out what: f(r-2)=6x+7 is
Answer:
f(r-2) = 6r -5
Step-by-step explanation:
f(r-2) is another notation for x = r-2
so we’ll plug in r-2 for x and solve:
f(r-2) = 6(r-2)+7
f(r-2) = 6r -12 +7
f(r-2) = 6r -5

Which equation represents a circle with a center at (2,-8) and a radius of 11
(x-8)^2+(y+2)^2=11
(x-2)^2+(y+8)^2=121
(x+2)^2+(y-8)^2=11
(x+8)^2+(y-2)^2=121
The second one, because when you square the right side of the equation you get 11 which is your radius. On the right side you get 2,-8 when you solve for the radius. aka solve for x and y

Tova has 17 marbles. The types of marbles she has are aggies, comets, and cats eyes. She has twictas many aggies as comets. She has 1 more cats eye than comets. She has 8 aggies. How many cats eyes does tova have?
Answer:
Tova has 5 cat's eyes.
Step-by-step explanation:
Use simple math to figure out the amounts. If she had twice as many aggies as comets, and the amount of aggies is 8, she had 4 comets. She had one more cat eye than comets. That means that she had 5 cat's eyes.
Answer: Tova has 5 cat's eyes.
