Find the value of x to the nearest tenth.<br> a. 11.3<br> b. 12.5<br> c. 12.9<br> d. 13.1
Scorpion4ik [409]

Answer:

B

Step-by-step explanation:

We have perpendicular bisector through a chord of the circle. We know the length, so either side of the chord is 11 due to the bisector cutting it directly in half. Since the radius is a fixed distance from the center to any point on the edge of the circle, we can draw the radius x from the circle to the end of the chord to form a right triangle.

We can use Pythagorean Theorem a^{2} +b^{2} =c^{2} to find the missing side length x. a=6, b=11 and c=x.

(6)^{2} +(11)^{2} =x^{2}

36+121=x^2\\157=x^2\\\sqrt{157}=x\\ 12.5=x

Steve needs to ship a box of dice, each of which is a cube with a volume of 1 cubic centimeter. How many dice can Steve fit in t
AfilCa [17]

Answer:

D. 1,944

Step-by-step explanation:

the box's size is missing, so I looked for a similar question:

the box measures:

  • base (12 cm)
  • width (9 cm)  
  • height (18 cm)

total volume of the box = 12 x 9 x 18 = 1,944 cm³

since each dice occupies a volume of 1 cm³, then you can fit 1,944 dices in each box.
