Deanna estimated the product of 6.45 and 10.2. How does the estimate compare to the exact product?

12345 [234]

The estimate should be 60 (because you round down the 6.45 and 10.2 to 6 and 10). Since you rounded down, the actual product will be greater than the estimate.

A car travels around a circular track of radius 1.5 miles. It traversed35of a complete revolution. Howfar did it travel?

Arturiano [62]

Answer:

The total distance traveled by the car is 330 miles.

Step-by-step explanation:

The circular track is the circumference of circle with radius 1.5 miles.

Circumference of a circle = 2 $\pi$ r

Thus,

Circumference of the track = 2 x $\frac{22}{7}$ x 1.5

= 9.4286571429

Circumference of the track = 9.4286571429 miles

But, one complete revolution by the car is the circumference of the track.

i.e One complete revolution round the track = 9.4286571429 miles

Therefore,

35 complete revolutions round the track = 35 x 9.4286571429 miles

= 330 miles

The total distance traveled by the car is 330 miles.

Solve the equation. 6x=2x^2+1

7nadin3 [17]

6x = 2x^2 + 1
2x^2 - 6x + 1 = 0
$x= \frac{-(-6) \pm \sqrt{(-6)^2-(4 \times 2 \times 1)}}{2 \times 2}\\=\frac{6\pm\sqrt{36-8}}{4}\\=\frac{6\pm\sqrt{28}}{4}\\=\frac{6\pm2\sqrt{7}}{4}\\=\frac{3\pm\sqrt{7}}{2}\\=\frac{3+\sqrt{7}}{2}\,or\,\frac{3-\sqrt{7}}{2}$
