First add all the items together:
6 + 4 + 7 + 4 = 21
then we compare 6 and 21 and look for common factors, 6 and 21 have the common factor 3 so we divide them both by 3 to get 2 and 7. since 2 and 7 have no common factors our answer is
2:7
This means for every 2 cans of fruit there are 7 total items and vice versa.
Answer:
a.–12 – 18
Step-by-step explanation:
We have to compute the difference (the subtraction) between the new, colder temperature, which is equal to -12 °C, and the original temperature, which is equal to 18 °C, that is:
colder temperature - original temperature
Replacing with data:
-12 °C - 18 °C = -30 °C
Answer:
the answer is the 3rd & 5th one for anyone doing this question ; )
Step-by-step explanation:
I just did this question
It's right i just checked
Frank can build a fence in twice the time it would take Sandy. Working together, they can build it in 7 hours. How long will it take each of them to do it alone?
Answer
If Frank and Sandy can build the fence in 7 hours, they must be building
1
7
of the fence every hour.
Now, let the amount of time it takes Sandy be
x
hours so that Frank takes
2
x
hours. Sandy can build
1
x
of the fence every hour and Frank can build
1
2
x
of the fence every hour.
We now have the following equation to solve.

Thus, Sandy takes

hours and Frank takes
21
hours.
Answer:
0
Step-by-step explanation:
Let us take sin(60 degree + theta) =x
Substituting x in equation
=> x-x
=> 0
