Answer:

y=-4x+17

Step-by-step explanation:

\begin{pmatrix}4&1\end{pmatrix}\quad \mathrm{and}\quad \begin{pmatrix}2&9\end{pmatrix}

\mathrm{Computing\:dot\:product\:of\:two\:vectors}:\quad \left(x_1,\:\:\ldots ,\:\:x_n\right)\cdot \left(y,\:\:\ldots ,\:\:y_n\right)=\sum _{i=1}^nx_iy_i

=4\cdot \:2+1\cdot \:9

=17

Sandra wants to give a party for 60 people. She has a punch recipe that makes 2 gallons of punch and serves 15 people. How many
zmey [24]

Answer:

8 gallons

Step-by-step explanation:

#1: Set up a ratio from the recipe: gallons of punch to the number of people.

2 gallons 15 people

#2: Set up a ratio of gallons to the people coming to the party.

(Place the gallons on top) x gallons 60 people

#3: Set up a proportion 2 gallons       x gallons

                                       15 people  =    60 people

* Like units should be across from each other

4) Solve using the "lonely mate" formula

2 gallons           x gallons

15 people  =     60 people

2 x 60 = 120

120/15 = 8

This means she should make 8 gallons.

Tessa shot 36 free Throws.she made 27 of them.what fraction of the free throws did she make?
frez [133]

For this case we have the following variables:

x: number of free throws that Tessa made

y: total number of free throws

We now write the relationship of free throws.

We have then:

\frac{x}{y} =  \frac{27}{36}

Simplifying the expression we have:

\frac{x}{y} = \frac{\frac{27}{3}}{\frac{36}{3}}  = \frac{9}{12}

\frac{x}{y} = \frac{\frac{9}{3}}{\frac{12}{3}}  = \frac{3}{4}

Answer:

The fraction of the free throws that she made is:

\frac{x}{y} = \frac{3}{4}
