What value should go in the empty box to complete the calculation for finding the product of 62.834 × 0.45? 62.834 times 0.45 gi
iVinArrow [24]
In this item, we are to supply for the missing term on one side of the equation. The left side is given to be composed of 62.834 x 0.45. The right hand side is given to be composed of 314170 along with a missing entity. 

Translating the given to mathematical expression and letting A be the unknown,
  62.834 x 0.45  = 314170 A

To determine the value of A, divide both sides of the equation by 314170.
             (314170A)/(314170) = (62.834 x 0.45) / 314170
                 A = 0.00009

The missing value is 0.00009 or 9.0 x 10^-5.

A basketball player is shooting a basketball toward the net. The height, in feet, of the ball t seconds after the shot is modele
tresset_1 [31]

Answer:

Yes, between 0.84 seconds and 0.85 seconds after the shot is launched.

Step-by-step explanation:

\text{The equation for ball height} : 6+30\cdot t-16\cdot t^{2}\\\text{The equation for shot blocker's height} : 9+25\cdot t-16\cdot t^{2}

But, the shot is made before two tenths of a second or 0.2 seconds therefore modified equation for ball height is :

6+30\cdot (t-0.2)-16\cdot (t-0.2)^{2}

Now for the shot to be blocked,the height of shot blocker must be greater than the height of the ball which is shot before 0.2 seconds :

\implies 9+25\cdot t-16\cdot t^{2}\geq 6+30\cdot (t-0.2)-16\cdot (t-0.2)^{2}\\\implies 9+25\cdot t-16\cdot t^{2}\geq 6+30\cdot t-6-16\cdot (t^{2}-0.4\cdot t+0.04)\\\implies9+25\cdot t-16\cdot t^{2}\geq 30\cdot t-16\cdot t^{2}+6.4\cdot t-0.64\\\implies 9+25\cdot t\geq 36.4\cdot t-0.64\\\implies 9.64\geq 11.4\cdot t\\\\\implies t\leq \frac{9.64}{11.4}\approx 0.846

Hence, the shot was blocked between 0.84 and 0.85 seconds after the shot is launched.

Answer:

15x+13y> 3,000

Step-by-step explanation:

We know that the floor ticket cost 15$ and the balcony cost 12$ so we put that in an inequality with their given variables. We also know they want to make more than 3,000 so it is a greater than symbol.
