Use estimation to help you choose the correct answer. 0.945 x 7.6 =

Mathematics
1 answer:
hoa [83]3 years ago
7 0

Remark

The thing you must not do is write 7.182 as your answer. That is the exact answer found using a calculator.


What to do.

What you should do is multiply two rounded numbers together.

7.6 rounded is 8 roughly


0.945 is almost 1.


Your answer is 8*1 = 8 roughly. This skill is very handy when you are writing a test and you want to see if you've done the question correctly. It is easy to misplace a decimal or put in incorrect digits and this is a quick check on things like that.

Help meh please=, and explain how you got ur answer please and thank you
vagabundo [1.1K]

Answer:

The answer is C. But I got 350.82

Step-by-step explanation:

The area for one triangle is 24 because A=h(height)b(base)timesb(base)/2. Both the triangles together would make 48 because 24+24=48

The are for one rectangle is 100.94 because A=b(base) times h(height). because there are 3 rectangles we multiply 100.94 times 3 which is 302.82

Then we add up all the areas 302.82+48 to get 350.82

Because this answer is slightly different I would assume it is C.

If my math is incorrect I apologize

I hope this helps! :)

Wait I just realized you have to convert it into square centimeters!

The decorating committee for a school
Schach [20]

Answer:

D. 160

Step-by-step explanation:

This question can be solved by proportions, using a rule of three.

In this question:

For each 3 white carnations, 5 yellows are needed, which leaves us with 8 total carnations. So for 60 white, the total is:

3 white - 8 total

60 white - x total

So

3x = 60*8

Dividing both sides by 3

x = 20*8 = 160

The correct answer is given by option D.
