Answer: options A, B and C are correct

Step-by-step explanation:

Ray's daily pay,P in dollars is given by the function, p(h) = 10h with h representing the number of hours that he worked on that day. If he worked c hours on Thursday and this is 3 hours more than he worked on Friday, then the following statement is true. We substitute c and c-3 for Thursday and Friday into the given function, p(h) = 10h

A) 10c -3 represents Ray's pay in dollars on Friday.

B) 10c represents Ray's pay in dollars on Thursday.

C) p(c ) - p(c-3) represents how much more Ray's pay was on Thursday than on Friday

In parallelogram JKLM, m<L exceeds m<M by 30 degrees. What is the measure of M<J?

Damm [24]

Answer:

2)105°

Step-by-step explanation:

In this parallelogram, J should be congruent to L (J=L). We can solve this problem if we find out the value of L.

The sum of the adjacent angle of the parallelogram will be equal to 180 degrees, so the equation is

L + M = 180

M=180- L

If L exceeds M by 30 degrees then the equation will be

L=M +30

If you combine both equations, it will be

L+30 = M +30

L+30 = (180- L) +30

L + L= 180 + 30

2L= 210

L=105

Heather had six 2-liter bottles of blood. She poured the blood into glasses which each have a capacity of 3 deciliters. How many

Flauer [41]

The human body has about 5.5 liters of blood
3 deciliters is about 0.3 liters
so 5.5/0.3=18.33333
so she could fill 18 and 1/3 glasses before she died
wait
oooooh, she has a supply of blood other than her own, nvm, I should read better

1 decileter is 1/10 of a liter
so 3/10 of a liter per glass

6 of those 2 liter bottles
so total is 6*2=12 liters
so
3/10 times number of glasses=12
times both sides by 10/3
number of glasses=120/3
number of glasses=40
can fill 40 glasses with the blood she is supplied (not including her own)
