Answer: D.1,250kj
Step-by-step explanation:
Hi, to answer this question we simply have to substitute mass= 3.75 and latent heat of fusion = 333 kj/kg in the equation given:
Q = mass x latent heat of fusion
Q = 3.75 kg x 333 kj/kg
Solving:
Q = 1,248 kj = 1,250kj (rounded)
The correct option is D.1, 250kj

Answer:
-1.9
Step-by-step explanation:
He has $1.10 in his printing account. 0.25 each sheet of paper.
47 pages.
He printed both sides so 47:2= 23.5.
Because he printed 2 pages then we divide by 2.
23.5:2=11.75
We cannot print a half of page, so we print 12 pages.
12*0.25=3
1.10-3=-1,9
His printing account will be in minus.
There is a common equation we use to find the Area of a trapezoid.
(a+b)h/2=A
Let's fill in what we know. We're not going to fill in any information about the bases.
(a+b)8/2=96
We can already tell that 8/2 will simplify to 4.
(a+b)4=96
Let's divide each side by 4.
a+b=24
Now, let's look at the information about the bases.
So, we will have this in terms of base a, since one base is longer than the other. This is how it'll look.
a +(a+6)=24
We can simplify that further.
2a+6=24
now subtract 6 from each side.
2a=18
Let's divide
9=a
So one side is 9, so the other one is 15. We should make sure everything makes sense by putting all the information in the formula to find area.
(9+15)8/2
24×4
96.
The lengths of the bases are 9 and 15 inches.
I think the answer is 4:24
Answer:-2
Step-by-step explanation:
slope = rise / run
y2-y1/x2-x1
(3,6) is the first set of coordinates
(5,2) is the second set of coordinates
2-6/5-3= -4/2= -2
