Answer:
Multiplying the mass of ice by the specific latent heat of fusion of ice
Step-by-step explanation:
The heat energy required to completely melt 100 grams can be calculated by multiplying the mass of ice (100g) by the specific latent heat of fusion of ice (336J/g)
Answer:
10 degrees
Step-by-step explanation:
1.) every triangle has angles that add up to 180 degrees
2.) a right triangle has a right angle and two acute angles
3.) right=90 degrees; acute=<90 degrees
4.) 90+80=170
5.) 180-170=10
Answer:
72 in^2
Step-by-step explanation:
The area of the square in the middle is
A = s^2 = 6^2 = 36
The area of the triangle on the left is
A =1/2 bh = 1/2 ( 6*6) = 18
The area of the triangle on the right
A = 1/2 bh = 1/2(6*6) = 18
Add the areas together
36+18+18 = 72
Answer:
D
Step-by-step explanation:
(x - 3)(x + 4) = x^2 + x - 12
F(x)=7-3x g(x)=3x-7
First let’s solve for f(1)
f(1)= 7-3(1)
f(1)= 7-3
f(1)= 4 *we will save this for later
Let’s now solve for g(1)
g(1)= 3(1)-7
g(1)= 3-7
g(1)= -4
Now we can find f(1) + g(1)
f(1) =4 and g(1)= -4
4+(-4) = 0
