What does multiply by the reciprical mean ???

1 answer:

7 0

It means multiply by the reciprocal of the number. The reciprocal is 1 divided by the number (x).

So assuming you're number is 3, the reciprocal of 3 would be 1/3.

or

Assuming the number is 0.2, the reciprocal of the number would be 1/0.2

A treasure map says that a treasure is buried so that it partitions the distance between a rock and a tree in a 5:9 ratio. Marin

sattari [20]

Answer:

Option B. is the answer.

Step-by-step explanation:

The given question is incomplete without the attachment; here is the attachment enclosed with the answer.

Since coordinates of the point representing rock is (3, 2) and coordinates of the tree are (16, 21) and treasure divides the line joining rock and tree in the ratio of 5:9.

We know the formula to get the coordinates of point P(x, y) joining (a, b) and (c, d) in the ratio of m : n is

P(x, y) = $[\frac{(mc+na)}{m+n}, \frac{(md+nb)}{m+n}]$

From the given formula,

Coordinates of treasure P = $[\frac{((5\times 16)+(9\times 3)}{(5+9)}, \frac{(5\times 21)+(9\times 2)}{(5+9)}]$

= $[\frac{(80)+(27)}{(14)}, \frac{(105)+(18)}{(14)}]$

= $[7.64, 8.78]$

≈ (7.6, 8.8)

Therefore, Option B will be the answer.

Tiffany sells two kinds of homemade tomato sauce. A quart of her Tuscan sauce requires 6 tomatoes and 1 cup of oil. A quart of h

nevsk [136]

From the problem,
x is the number of quarts of Tuscan sauce and
y is the number of quarts of marinara sauce

We add the following variables
t as the number of tomatoes
c as the number of cups of oil
z is the total profit

The constraints are the following
x = 6t + c
y =5t + 3c
6t + 5t ≤ 45
c + 3c ≤ 10
z = 4x + 5y
where z is to be maximized
