Mary's 3 hamsters each eat three-eighths of cup of grain a day, if she has 6 and 3/4 cups of grain, how many days will the grain last?

6 days

Step-by-step explanation:

Each hamster eat of a cup of grain a day.

So in one day, the three hamsters eat:

cups

And since we know that Mary has 6 cups of grain.

We need to convert this quantity into a fraction:

she has cups of grain.

To find how many days the grain will last, we need to divide the total amount of grain she has ( cups) by the amount that the three hamsters eat together in one day ( cups):

÷

and we use the rule to divide fractions:

÷

this way we get:

÷

the grain will last 6 days

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
