Each centimeter is three people so you just have to count the centimeter and multiply that by three to get the answer

History 6 friends
Eng/sci 15 friends

Answer: For part A, Yakob has 9 friends that like Maths best, 6 friends that like History the best, & 15 friends that prefer <em>either</em> English or Science the best.

Part B: There's a graph I made below.

Step-by-step explanation:

You have to use proportions to answer this question. The bar graph is 10 cm total, therefore it is proportional to the 30 friends that Yakob has in total. After that, you can make proportions out of the data in the chart. For example, History is 2 cm out of the 10 cm total. Think proportions! You had to multiply 3 to 10 to get 30, so you have to apply the same thing to the numerator. In this case, multiply 3 to 2 and you'll get 6. 2/10=6/30! I repeated that for the rest and put it into a graph. The prompt wanted you to combine English and Science, so I did that after separately making their proportions. Hope this helps!

20. Find the measure of each interior angle AND each exterior angles of the following regular polygons. Show your work.

Lelu [443]

Pentagon has 5 angles. 360/5= 72 degrees
16-gon has 16 angles. 360/16= 22.5 degrees
dodecagon has 12 angles. 360/12= 30 degrees
The measure of the exterior angle of any regular polygon is 360 divides by the number of sides the polygon has.

Select the correct answer.

Musya8 [376]

Answer:

Before Tim ate any of the jellybeans, here are numbers:

pineapple or p =10

raspberry or r = 10

orange or o = 10

Tim has eaten 6 orange and 4 pineapple jellybeans. Hence, what's left are:

p = 10-4 =6

o = 10-6 =4

r = 10 so now total jelly beans are 20

So the probability of getting a raspberry is:

p(r) = number of r/total

10/20 or 50%

Priya bought these items at the grocery store. Find each unit price. A. 12 eggs for $3. How much is the cost per egg? B. 3 pound

Ratling [72]

Answer: A. Cost per egg = $4 .

B. Cost per pound = $ 2.5

C. Cost per roll = $ 0.5

D. Cost per apple = $0.35

Step-by-step explanation:

Formula: cost per item = (total cost) ÷ (number of items)

A. 12 eggs for $3.

Cost per egg = $ (12÷3) = $4

So, Cost per egg = $4 .

B. 3 pounds of peanuts for $7.50

Cost per pound of peanuts = $ (7.50 ÷ 3)= $ 2.5

So, Cost per pound = $ 2.5

C. 4 rolls of toilet paper for $2.

Cost per roll = $ (2 ÷4 ) = $ 0.5

So, Cost per roll = $ 0.5

D. 10 apples for $3.50.

Cost per apple = $ (3.50 ÷ 10)= $ 0.35

So, Cost per apple = $0.35
