He can buy 20, because half of 100 is 50 since he wants to leave with at least 50 dollars, then you divide 2.50 from 50 and the answer is 20 tickets that he can buy

100 - 50 = 50
50/2.50 = 20
Subtract 50 from the original $100 to find out the most he can spend and still have $50 left.
This amount $50 is then divided by the price of each raffle ticket $2.50, and he can buy 20 tickets.

write the equation of a line in slope intercept form that is parallel to the line x+5y=10 and goes through the point (-5,6)
lilavasa [31]

Answer:

The equation would be y = -1/5x + 5

Step-by-step explanation:

To find the equation of this new line, we first need to identify the slope of the first line. We do this by putting it into slope intercept form.

x + 5y = 10

5y = -x + 10

y = -1/5x + 2

In slope-intercept form, the slope is always the coefficient of x. This makes the slope of the first equation -1/5. Since parallel lines have the same slope, our new slope will also be -1/5.

Given that and the point, we can solve for the equation using point-slope form.

y - y1 = m(x - x1)

y - 6 = -1/5(x + 5)

y - 6 = -1/5x - 1

y = -1/5x + 5

Tell which equation you would choose to solve for one of the variables when solving the system by substitution. 2x+3y=5 4x-y=3
PtichkaEL [24]

i would solve 4x-y =3 for y because  the coefficient for y is 1

subtract 4x from each side

-y = -4x+3

divide by -1

y = 4x-3

A kitchen sink has a volume of 1800 cubic inches.What is the volume of a similar sink that is larger by a scale factor of 2
bonufazy [111]

Answer:

14400 cubic inches.

Step-by-step explanation:

Let l, b and h are length, breadth and height of a cuboid respectively, then

V=l\times b\times h

If another cuboid is larger by a scale factor of k, then kl, kb and kh are length, breadth and height of new cuboid respectively.

V_1=kl\times kb\times kh

V_1=k^3(l\times b\times h)

V_1=k^3V       ...(i)

It is given that a kitchen sink has a volume of 1800 cubic inches and a similar sink is larger by a scale factor of 2.

Substitute k=2 and V=1800 in equation (i).

V_1=2^3(1800)

V_1=14400

Therefore, the volume of required sink is 14400 cubic inches.
