Answer:

Step-by-step explanation:

The discriminant is what's under the square root sign in the quadratic equation.  The equation for the discriminant is b^{2}-4ac, where b is the coefficient of x, a is the coefficient of x^{2}, and c is the number with no variable attatched to it.  If we plug in the numbers (17^{2} -4*4*3) it gives you 241, which is the discriminant.  Since 241 is more than zero, it has 2 zeros.  If the discriminant was 0, there'd be 1 zero, and less then zero there would be zero zeros.

If a machine that prints designs on T-shirts prints 500 shirts in 3 hours, how many hours will it take to print designs on 1300
nataly862011 [7]

Answer:

It will take 7.8 hours to print designs on 1300 shirts

Step-by-step explanation:

We will use the ratio method to solve this question

∵ A machine prints designs on T-shirts

∵ It prints 500 shirts in 3 hours

∵ x is the number of hours to print 1300 shirts

→ By using the ratio method

→  shirts  :  hours

→   500   :  3

→  1300   :  x

→ By using cross multiplication

∵ 500 × x = 1300 × 3

∴ 500x = 3900

→ Divide both sides by 500

∴ x = 7.8

∴ It will take 7.8 hours to print designs on 1300 shirts

Lamont is making a blue print of his shoebox. He made a drawing of how he would like to make the box. If the drawing is 4 inches
Alchen [17]

Answer:

The box is 8 feet long.

Step-by-step explanation:

1 inch = 2 feet.

Multiply 4 by 2.

4×2=8

I multiplied 4 by 2 because 1-inch equals 2 feet, which means if we multiply both terms by 4, you will get 4 inch = 8 feet.

Hope this helps!
