Answers

Answer 1

Answer:

The circumference of small size, medium size and large size of pizzas are 25.12 inches, 31.4 inches and 37.68 inches.

Step-by-step explanation:

Given,

The diameter of small pizza = 8 inches,

The diameter of medium pizza = 10 inches and

The diameter of large pizza (d) = 11 inches

To find, the circumference of each size of pizza = ?

We know that,

The circumference of the circle = $2\pi r= \pi d$

∴ The circumference of small size of pizza = 3.14 × 8 = 25.12 inches

The circumference of medium size of pizza = 3.14 × 10 = 31.4 inches

Also,

The circumference of large size of pizza = 3.14 × 12 = 37.68 inches

Thus, the circumference of small size, medium size and large size of pizzas are 25.12 inches, 31.4 inches and 37.68 inches.

22. If you add a number to a series of data, and it doesn't change the mean, that number MUST equal the mean. Try adding the mean number into it, hopefully it doesn't change the mode or median either.

23. Basically I think (can't quite read all the question!) just work out the circumference of a circle with radius 20 feet (urgh imperial), ie 2*pi*r so 40pi.

22.
mode=the number that occurs most in the set of numbers
median=if the number are in increasing order, the number in then middle
mean=average or if all the number are added together and divided by the number of numbers, you get the average, exg mean of 2,3,4=(2+3+4)/3=9/3=3

the numbers are
91,93,93,95,98,100
mode, the number that occurs most is 93
mediann, there are 6 numbers so there is no middle number
we must fix that
first find teh mean
91+93+93+95+98+100 divide by6=95
therefor the mean is 95
the easiest way to make the mean meadian and mode the same is add 2 more 95's into the order

91,93,93,95,95,95,98,100
mode=number occurs most=95
median=middle number=95
mean=91,93,93,95,95,95,98,100 added tother and divided by 9=95

the order is 91,93,93,95,95,95,98,100

23. so the circle that he can walk around, is representing the circumference of the circle
20 is the radius
circumference=2 times pi times raidus

c=2(pi)20
c=40pi
c= aprox125.664

the dog can walk 125.7 feet before returning to start

We know that for every 5 red bricks there were 2 gray bricks.

The total amount of red bricks and grey bricks in this sample is 7.

5 red bricks + 2 grey bricks = 7 bricks

Now, we divide 175 "total number of bricks used" by 7 "5 red bricks + 2 grey bricks = 7 bricks" and we will get a quotient of 25.

Now we know that 25 bricks is $(1)/(7)$ of the wall. The gray bricks are $(2)/(7)$ so we can multiply 25 by 2 and we will get a product of 50. If 1/7 = 25 grey bricks so 2/7 would be the grey bricks.

175 - 50 = number of red bricks.

Therefore, there were 125 red bricks.

There were 125 bricks knowing that for every 5 bricks there are 2 gray bricks

A rectangular card has an area of 120 over 1\4 square inches. The card is 6 over 1\2 inches wide. How long is the card???? if u need me to display answers A., B., C, D send me a message or comment. thank ya!

Answers

the area is 120/(1/4) or 120 x 4 or 480 square inches
the width is 6/(1/2) or 6 x 2 or 12 inches
to find the length, divide the area by the width
480/12= 40
40 inches
