Answer:

95 German Shepherds

Step-by-step explanation:

Looking at the pie chart, 4 out of 9 are bulldogs and 5 out of 9 are german shepherds. You can find the difference by taking the total and multiplying it by the fraction.

So it would look like this:

171 × 5/9 = 95

The spherical bottle has a conical shaped lid with a diameter of 5cm and a height of 4.5cm. Given this information, calculate th
Harlamova29_29 [7]

Answer: Volume of lid = 29.44 cubic cm and surface area = 40.41 cubic cm.

Step-by-step explanation:

Given: For  lid of the spherical shaped bottle,

Diameter = 5 cm

Height = 4.5 cm

Radius = Half of diameter = 2.5 cm

Volume of cone = \dfrac13\pi r^2 h

Volume of lid  =\dfrac13(3.14)(2.5)^2(4.5)=29.4375\approx29.44\text{ cm}^3

Surface area of cone = \pi r\sqrt{h^2+r^2}  [as lide has no base we don't include area of base.]

Surface area of lid = (3.14)(2.5)\sqrt{(2.5)^2+(4.5)^2}= 7.85\sqrt{26.5}\approx40.41\text{ cm}^3

Hence, volume of lid = 29.44 cubic cm and surface area = 40.41 cubic cm.

A number is called evil if it has 666 in it. How many 7 digit numbers are evil?
defon

Step-by-step explanation:

There are 5 different positions of 666:

666////

/666///

//666//

///666/

////666

The forward dashes represent any number from 0 to 9.

Case 1: "666////"

Number of ways = 10⁴ = 10,000.

Case 2: The other positions.

Since the 1st forward dash cannot be 0 (leading digit),

Number of ways for each position = 9 * 10³ = 9,000

Number of ways for all 4 positions = 9,000 * 4 = 36,000.

Total evil numbers = 10,000 + 36,000 = 46,000.
