Find the distance of the following points from the x axis: P(3,0) , Q(0,-3) , R(12,-4) , S(-4,-3)
OverLord2011 [107]

Answer:

Distance of point P(3,0) from x axis is zero as this point lies on x axis.

distance of point Q is 3.

Distance of point R is 4.

Distance of point S is 3.

Step-by-step explanation:

Point P already lies on x axis as its y coordinate is zero so its distance from x axis is zero

distance of points Q , R and S is the absolute value of their y coordinates that is 3 , 4 and 3 respectively.

Mrs.Manning is making cookies for the bake sale. She jas 3/4 cup of flour and needs 1/3 cup of flour for her chocolate chip cook
Sedbober [7]

Answer:

<em>The fraction of the flour Mrs. Mannng will use for her chocolate chip cookies is 4/9</em>

Step-by-step explanation:

<u>Fraction of Portion</u>

Suppose we have a number n and another number m such as m>n. The portion or fraction of size n of m is given by the quotient n/m.

For example, 3 pieces of cake out of a total of 6 make them a fraction of 3/6 = 1/2 of the whole cake, i.e. half of the total available.

Mrs. Manning needs 1/3 cup of flour to make cookies for the bake sale. She actually has 3/4 cups of flour. Calculate the fraction of needed against the available flour:

\displaystyle \frac{\frac{1}{3}}{\frac{3}{4}}

The division can be easier performed by multiplying by the reciprocal of the denominator:

\displaystyle \frac{1}{3}\cdot \frac{4}{3}=\frac{1*4}{3*3}

\displaystyle =\frac{4}{9}

The fraction of the flour Mrs. Mannng will use for her chocolate chip cookies is 4/9
