y =  - 3 {x}^{2}  - 12x + 17 \\ x_0 =  \frac{ - b}{2a }  =  \frac{12}{ - 6}  =  - 2 \\ y_0 =  - 3 \times  {( - 2)}^{2}  - 12 \times ( - 2) + 17 = 29

Maybe i did something wrong, maybe your question is incorrect, but the vertex is (-2; 29)

five people, each working 8 hours a day, can assemble 400 toys in a five day work week. what is the average number of toys assem
vladimir1956 [14]

The question asks for the rate of toys per hour.

So we shall divide the total toys assembled by the total hours.

Its a five day week.

The number of hours allotted per day are 8.

So total allotted during the week are 8 × 5 = 40 hours.

Number of toys made during the week are 400.

Hence the number of toys assembled per hour per person

= number of toys / number of hours

= 400 / 40

= 10 toys per hour per person.

The average number of toys assembled per hour per person is 10.

Ierofanga [76]

Answer:

54, 486, 154

Step-by-step explanation:

x+9x+100+x= 694

11x= 694-100

11x=594

x= 54

54×9=486

54+100= 154

54+486+154=694.

Alex has a grid in the shape of a rectangle. he has right triangles. each right triangle has an area of 25 square millimeters an
Maurinko [17]
First you have to find the area of the rectangular grid. The area of a rectangle is length•width.
So:
A= 20•12
A= 240cm
Then you need to convert 240cm into mm.
240cm is 2400mm.

Then you need to figure out how many triangles can fit into the rectangle if all the triangles have an area of 25mm. So you divide 2400 by 25.
2400:25= 96

So Alex can fit 96 triangles into the grid.
