a pizza is 16 inches in diameter. each square inch of pizza has 6 calories. if each slice contains about 144 calories, how many

slices is the pizza cut to with explanation

First find the area of the pizza:

area = PI x r^2
diameter = 16 inches...radius = 16 /2 =8 inches

area = 3.14 x 8^2 =  3.14 x 64 = 200.96 sq inches. Round to 201 square inches

the pizza has 6 calories per square inch so now multiple the total square inches by 6 to get total calories:

201 * 6 = 1206 total calories

now divide total calories by 144 to find the number of slices:

1206 / 144 = 8.375 so the pizza can be cut into 8 slices and each slice would have a little over 144 calories

Help AB and CD are straight lines find z​
chubhunter [2.5K]

Answer: z=16

Step-by-step explanation:

Angles on a straight line add up to 180.

As AB is a straight line we can use that to help us find z.

So you would do 68+85+11=164 (I got the 11 from the angle trapped between like C and F as opposite angles are the same).

Then you would do 180-164=16

So z=16

Hope this helps :)

it takes Joey 1/16 of an hour to write one Thank you card how many cards can he write in 3/4 of an hour?
bearhunter [10]

To solve this problem you will need to use the cross product method:

1/16 of an hour → write 1 card

3/4 of an hour → write X cards


(3/4) ÷ (1/16) = X


0.75 ÷ 0.0625 = X


12 = X


Joey can write 12 Thank you cards in 3/4 of an hour.


There you go! I really hope this helped, if there's anything just let me know! :)

5. A yacht is cruising at 20 knots at bearing of 185° when a 15 knot wind starts to blow at a bearing of 290°. Find the directio
kicyunya [14]

Answer:

<em>Direction of the boat is 43.05° and the speed is 21.66 knot</em>

<em></em>

Step-by-step explanation:

yacht speed = 20 knots

yacht bearing = 185° = 85°  below the negative horizontal x-axis

wind speed = 15 knots

wind bearing = 290° = 20° above the negative horizontal x-axis

we find the x and y components of the boat velocities

for yacht,

x component = -20 cos 85° = -1.74 knots

y component = -20 sin 85° = -19.92 knots

for the wind,

x component = -15 cos 20° = -14.09 knots

y component = 15 sin 20° = 5.13 knots

total x component  Vx = -1.74 + (-14.09) = -15.83 knots

total y component Vy =  -19.92 + 5.13 = -14.79 knots

Resultant speed of the boat = \sqrt{Vx^{2} + Vy^{2}  }

==> \sqrt{15.83^{2} + 14.79^{2}  } = <em>21.66 knot</em>

<em></em>

direction of boat = tan^{-1} \frac{Vy}{Vx}

==> tan^{-1} \frac{14.79}{15.83} = <em>43.05°</em>
