olga55 [171]3 years ago
4 0

Answer:

Each tray has 5 colours and one of the colour on the tray is purple. Hence 1/5 of the colours on the tray is purple and thus 1/5 of the colours on the 20 trays is purple. The fraction of colours on the trays will not change. If written out logically, 20 purples out of 100 colours in total on the trays will also given the fraction 1/5.

Find the slope of the line passing through the points (7, 8) and (-7, 1). Show your work.
anygoal [31]

Answer:

The slope is \frac{1}{2}

Step-by-step explanation:

∵ The rule of the slope passing through 2 points is:

m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

∵ The points are (7 , 8) and (-7 , 1)

∴ m = \frac{1-8}{-7-7}=\frac{-7}{-14}=\frac{1}{2}

If a large cylinder has a volume of 28260 cubic cm, how many cylinders can be filled out of the large cylinder if the small cyli
inysia [295]
Hi,

To find the number of small cylinders that fit inside the big cylinder. You need to divide volume of small cylinder with the volume of big cylinder. We do this by using formula to calculate volume of cylinder:


v = \pi \times  {r}^{2}  \times h


To find radius just divide diameter with 2.

v = \pi \times   {2}^{2}  \times 6 \\ v = \pi \times 4 \times 6 \\ v = \pi \times 24 \\ v = 3.14 \times 24 \\ v = 75.4 {cm}^{3}


Now just division:

28260 \div 75.4 = 374.8

Answer: You could fit 374.8 smaller cylinders inside a big cylinder.

Hope this helps.

the sum of two numbers is 44. the smaller number is 20 less than the larger number. what are the numbers?
Troyanec [42]
Sum means add
x and y are the numbers
sum i 44
x+y=44

smaller s 20 les than larger
x=20+y
or
y=20+x
doesn't matter, just pick one
x=20+y

substue 20+y for x since they are equal
x+y=44
(20+y)+y=44
20+y+y=44
20+2y=44
subtract 20 from both sides
2y=24
divide by 2
y=12
subsitue
x=20+y
x=20+12
x=32

the numbers are 12 and 32
