1.5 sticks of butter for 24 cookies
48 / 24 = 2        1.5 * 2 = 3
3 sticks of butter for 48 cookies (double the cookies, double the butter)
72/24 = 3         1.5 * 3 = 4.5
4.5 sticks of butter for 72 cookies (triple the cookies, triple the butter)

24 = 3 sticks
72 = 4.5 sticks

Let x represent the amount of sticks of butter you need
First of all, we will find the amount of sticks of butter needs for 48 cookies by using Tree Diagram and Cross Multiply
1 1/2 sticks of butter:24 cookies
Or
3/2 sticks of butter:24 cookies
x sticks of butter:48 cookies
Use cross multiply
48*3/2=24*x
72=24x
Divided 24 to each side
72/24=24x/24
x=3 sticks of butter, so you will need 3 sticks of butter to make 24 cookies
Or
We know that 48 cookies is double 24 cookies. In conclusion, we know that the amount to make 48 cookies is double, so
1 1/2*2
=3/2*2
=3 sticks of butter

Next,
1 1/2 sticks of butter:24 cookies
x sticks of butter:72 cookies
Use cross multiply
1 1/2*72=24*x
3/2*72=24x
108=24x
Divided 24 to each side
108/24=24x/24
x=108/24
x=54/12
x=27/6
x=9/2
x=4.5 sticks of butter, so you will need 4.5 sticks of butter for 72 cookies. Hope it help!

Can the polynomial equation have exactly 1 real solution, including any repeated solutions? (Use the Fundamental Theorem of Alge
Kryger [21]

yes, there are infinitety many polynomial that have exactly one real root just like your example, to determine the real root first let the real root is a, and the complex roots are b±ic the polynomial satisfy

-9x³ + 19x² + 17 = -(x - a)(x - b - ic)(x - b + ic)

9x³ - 19x² - 17 = (x - a)(x - b - ic)(x - b + ic)

Pls help I'm bad at math v.v<br><br> Lines m and n are parallel.
Eva8 [605]

Answer:

The measure of angle 1 is 55.

Step-by-step explanation:

The top angle= 75 because of the vertical angle theorem

The right angle= 50 because of the alternate exterior angle theorem

75+50=125

There are 180 degrees in a triangle so the angle has to equal 55

(5 points) An urn contains two blue balls denoted by B1 and B2, and three white balls denoted by W1, W2 and W3. One ball is draw
never [62]

Answer:

The probability of the event that first ball that is drawn is blue  is \frac 25.

Step-by-step explanation:

Probability:

If S is is an sample space in which all outcomes are equally likely and E is an event in S, then the probability of E,denoted P(E) is

P(E)=\frac{\textrm{The number of outcomes E}}{\textrm{The total number outcomes of S}}

Given that,

An urn contains two balls B₁ and  B₂ which are blue in color and W₁,W₂ and W₃ which are white in color.

Total number of ball =(2+3) =5

The number ways of selection 2 ball out of 5 ball is

=5²

=25

Total outcomes = 25

List of all outcomes in the event that the first ball that is drawn is blue are

B₁B₁ , B₁B₂ , B₁W₁ , B₁W₂ , B₁W₃ , B₂B₁ , B₂B₂ ,  B₂W₁ , B₂W₂ , B₂W₃

The number of event that the first ball that is drawn is blue is

=10.

The probability of the event that first ball that is drawn is blue  is

=\frac{10}{25}

=\frac25

A line is parallel to y= 4x-2 and intersects the point (5,-11). what is the equation of this parallel line?
mina [271]

The equation of line parallel to given line is: y=4x-31

Step-by-step explanation:

Given equation of line is:

The equation of line is in slope-intercept form so the co-efficient of x is the slope of the line.

Let m1 be the slope of the given line

then

m1 = 4

Let m2 be the line that is parallel to given line

As we know that the slopes of parallel lines is equal so

m1=m2 = 4

The slope-intercept form of equation of line is:

Putting the value of slope

to find the value of b, putting (5,-11) in the equation

Putting the value of b

Hence,

The equation of line parallel to given line is: y=4x-31

Keywords: Equation of line, slope
