A bakery has bought 15 pounds of flour. They are going to use it to make bread and donuts. A loaf of bread requires two pounds of flour, and a dozen
donuts requires one pound of flour. It takes bakers 5 minutes to make a
loaf of bread, and 3 minutes to make a dozen donuts. Their profit will be
$3.00 on a loaf of bread, and $1.50 on a dozen donuts.
Determine the variables for the above situation.

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
