How many times does 5.4 go into 60 if it starts at -18?

photoshop1234 [79]

Answer:

14 $\frac{4}{9}$

Step-by-step explanation:

starting at -18 you must add 5.4 until you reach 60

-18 + 5.4 = -12.6 once (1)

-12.6 + 5.4 = -7.2 twice (2)

-7.2 + 5.4 = -1.8 thrice (3)

-1.8 + 5.4 = 3.6 fourth (4)

3.6 + 5.4 = 9 fifth (5)

9 + 5.4 = 14.4 sixth (6)

14.4 + 5.4 = 19.8 seventh (7)

19.8 + 5.4 = 25.2 eighth (8)

25.2 + 5.4 = 30.6 ninth (9)

30.6 + 5.4 = 36 tenth (10)

36 + 5.4 = 41.4 eleventh (11)

41.4 + 5.4 = 46.8 twelth (12)

46.8 + 5.4 = 52.2 thirteenth (13)

52.2 + 5.4 = 57.6 fourteenth (14)

since 57.6 + 5.4 is over 60, we need to find the difference in how much we need

57.6 - 60 = -2.4

we need 2.4 so subtract by 5.4

5.4 - 2.4 = 3

therefore we should divide

$\frac{2.4}{5.4}$ = 14.444...

which means it goes into 60 (starting at -18) 14.444... repeating times

another way to find the answer is

add 18 + 60

18 + 60 = 78

78/5.4 = 14.444... repeating or 14 $\frac{4}{9}$

hope this helps:)

Please help me on #18, don't know how to do the question.

Option B) Determine the volume of the cake V= πr²h and divide that amount by 18

Step-by-step explanation:

It is given that, the birthday cake is in the shape of the cylinder.
Therefore, to find the entire volume of the cake, the volume of the cylinder formula is used.

The volume of the cylinder is given by,

Volume of the birthday cake = πr²h

After that, it was asked to find the volume of each piece of the cake.

In this case, the birthday cake is cut into 18 pieces.

We already know the total volume of the birthday cake which is πr²h.

In order to find the volume of each piece of cut cake, the total volume must be divided by the number of parts it has been cut into pieces.

Here, the whole part of the cake is 1.

The number of parts it has been divided after it is made into pieces = 18 parts.

Therefore, the volume of the birthday cake must be divided by 18 to get the volume of each piece of cake.

Option B) Determine the volume of the cake V= πr²h and divide that amount by 18 is correct.

How do you graph a line written in standard form

Sonbull [250]

Ok so standard form is a bit tricky, but I’ll help explain

Here’s and example:

If you have 2x+5y=10 here is how you would solve it

First you divide the x value by what the number is equal to (in our example, 10), and then we get 10/2 is 5. So now we know that

x is equal to five

Keep that in mind. Now we just have to do the same thing for the y value. 5/10 is 2, so you know that

y is equal to two

NOW you put those two together, and graph on the intercepts (the positions on the y and x axis where the lines intercept)

You would put a line on the x axis at 5, and on the y axis at 2

If you have any questions, you can ask
