Ella is baking cookies to put in packages for a fundraiser. Ella has made 86 chocolate chip cookies and 42 sugar cookies.
Ella wants to create identical packages of cookies to sell, and she must use all of the cookies.
What is the greatest number of identical packages that Ella can make?
Multiply the denominators to make it one fraction.
Now for the numerator, you multiply the numerator of the the 1st fraction with the second fractions denominator. Then Multiply the 1st fractions denominator with the 2nd fractions numerator. Now with those two numbers you Subtract it. Whatever number you get is the numerator. So there is the fraction. You would just simplify it. (IF you want to add fractions instead of subtracting the numerators, you add the numerators. Like instead of 68-12 you would do 68+12
Part A: Let the September price be x, then
1.2x = 1.5
x = 1.5/1.2 = 1.25
Therefore, September price is $1.25
Part B: In September, they earned 0.4 * 1.25 * 900 = $450
In October, they earned 0.4 * 1.5 * 700 = $420
Therefore, they earned more money in September.
For a) the pattern rule goes 12+(12x2)=36 36+(12x4)=84
So the pattern rule is double the number and then times it by twelve to get to the next answer
Answer:
d, 1/6
Step-by-step explanation:
so i did a diagram of some sorts to do this and got around six possible outcomes.
h is heads, t is tails.
h-h-h
t-t-t
h-t-h
t-h-t
t-t-h
h-h-t
feel free to correct me if any of this is wrong.
Given a scalar number
and a vector
v, the product between
and
v is a vector, with
- magnitude given by the product between the absolute value of
and the magnitude of
v- direction given by the sign of
: if a is positive, the final vector has same direction of
v; if a is negative, the final vector has opposite direction to
v.
In our problem, the scalar number is
. This means that the product between the vector and this number:
- has magnitude equal to
times the magnitude of the vector
- has opposite direction with respect to the original vector (because the scalar
is negative)
Therefore, the correct answer is
<span>B.) The vector will change direction and decrease in magnitude.</span>
