The measure of B will be given by:
cos θ= adjacent/hypotenuse
θ=B
adjacent=a=2
hypotenuse=c=√5
thus;
cos B=2/√5
thus
B=arccos 2/√5
B=26.565°~26°
Answer:
85 + z <= x <= 255 + z
Step-by-step explanation:
An inequality system will be given by a lower limit and an upper limit, therefore it is only necessary to raise an equation for each case, h being the hours worked and z the extra money you can earn by delivering the pizzas:
For the lower limit:
8.5 * h + z, knowing that in this case it is 10 hours.
85 + z would be the lower limit value
For the upper limit:
8.5 * h + z, knowing that in this case it is 30 hours.
225 + z would be the upper limit value
Therefore the inequality system would be as follows, let x be the money earned:
85 + z <= x <= 255 + z
Which means that the money earned will be determined by the previous inequality.
Answer:
Step-by-step explanation:
Given
See attachment for chart
Required:
Lemons used in first 4 hours
First, we calculate the number of lemon sold in the first 4 hours.
Represent the number of cups of lemonades needed with x
So, we have:
and
Cross Multiply:
Make x the subject
cups
It would 100% be 5.
but my explanation is kind of by look, basically it is one more than the four and one less than the 6 :)
each of the ‘B’s in 8b
Step-by-step explanation:
it’s the B’s by 8 because a coefficient on google multiples letters or variables
