Answer:
$15.6 or $16
Step-by-step explanation:
simply multiply 8 2/3 to $1.80
31 + (4*2^2 + 8*2) + (3*2^2 + 5*2 + 20) + (7*2 + 30) = 129
Answer:
The number of students who received the paint=5 students
Step-by-step explanation:
Step 1: Determine amount given to each student
Quantity per student=1/7 gallon per student
Step 2: Determine the total amount of paint Mrs. Jennings had
The total quantity of paint Mrs. Jennings is:
Initial quantity of paint=5/7 gallon
Step 3: Calculate number of students who received the paint
The number of students who received the paint can be expressed as;
Initial quantity of paint=Quantity per student×number of students
where;
Initial quantity of paint=5/7 gallons
Quantity per student=1/7 gallons
number of students=n
replacing;
5/7=(1/7)×n
n=(5/7)×7
n=5
The number of students who received the paint=5 students
Answer:

And replacing we got:

And we can find the angle with the inverse cosine function and we got:

Step-by-step explanation:
for this case we can use the following identity:

We can begin finding the norm for each vector and we got:


Now we can find the dot product and we got:

And replacing we got:

And we can find the angle with the inverse cosine function and we got:
