3 cups left.

David biked a total of 158 miles (option C)

Why?

- First exercise:

To solve the problem we need to consider that for each 1/2 cup of cornmeal, we will have 6 corn muffins.

So, calculating we have:

$TotalMuffins=24=4*6\\\\UsedCups=\frac{1}{2}*4=2Cups$

We can see that, if each 1/2 cups can give us 6 corn muffins, 2 cups can give us 24 corn muffins.

$CupsLeft=5cups-2cups=3cups$

Hence, there are 3 cups left.

- Second exercise:

We can solve the problem by multiplying or adding the fractions according to the number of dots assigned to each one.

So, calculating we have:

$FirstDay=10miles*2=20miles\\SecondDay=10\frac{1}{2}miles=10.5miles\\ThirdDay=11miles*3=33miles\\FourthDay=11\frac{1}{2}miles*4=11.5miles*4=46miles\\FifthDay=12miles*3=36miles\\SixthDay=12\frac{1}{2}miles=12.5miles$

$Total=20miles+10.5miles+33miles+46miles+36miles+12.5miles\\Total=158miles$

Hence, we have that David covered a total 158 miles. (Option C)

Have a nice day!

According to the Rational Root Theorem, which function has the same set of potential rational roots as the function g(x) = 3x5 –

elena55 [62]

Answer:

Step-by-step explanation:

Given is an algebraic polynomial of degree 5.

$g(x) = 3x^5-2x^4+9x^3-x^2+12\\$

Here leading term is p=3 and constant term is q =12

Factors of p are ±1,±2,±3

Factors of q are $\frac{±1,±2,±3,±4,±6,±12} \\$

Possible forms of p/q will be the same for any other polynomial of degree 5 with leading term =3 and constant term = 12

Hence any other polynomial

$g(x) = 3x^5+ax^4+bx^3+cx^2+12$

will have same possible zeroes of p/q, when a,b,c are rational.

Hence any polynomial of this type would have the same possible rational roots.

Write the equation of a line through (2, -3), perpendicular to y = 1/3x

REY [17]

to make a perpendicular function from another we must take its slope and make two transformations

the slope of y=1/3x is 1/3

the transformations:

reverse the number

$\frac{1}{3}\longrightarrow\frac{3}{1}=3$

and change the sign

$3\longrightarrow-3$

ok we have the slope now need the general equation of the line

$y=mx+b$

where m is the slope , b a cut point and (x,y) a point

so, we have the slope=-3 , and the point (2,-3) we can replace to find b

$\begin{gathered} (-3)=(-3)(2)+b \\ -3=-6+b \\ b=-3+6 \\ b=3 \end{gathered}$

now we can replace b and the slope to have the final equation

$y=-3x+3$
