Numerical expressions contain numbers, while algebraic expressions contain variables and numbers.
<u>Numerical Expression</u>
"Difference" indicates that we'll be subtracting 13 from 48.
48 - 13 = 35
<u>Algebraic Expression</u>
Variables represent the unknown number, in this case the difference between 48 and 13. Let d represent the difference between the two.
48 - 13 = d
35 = d
Answer:
x ≈ 10.92
Step-by-step explanation:
Using the sine ratio in the right triangle
sin83° = 
= 
Multiply both sides by 11
11 × sin83° = x, thus
x ≈ 10.92 ( to 2 dec. places )
Answer:
87.5 ft^3
Step-by-step explanation:
Formula:
Volume = length x width x height.
Dimensions:
Length = 3 1/2 ft = 7/2 ft
Width = 5 ft
Height = 2 1/2 ft = 5/2 ft
Substitute and Find Volume:
Volume = (7/2 ft) x (5 ft) x (5/2) ft
Volume = 87.5 ft^3
-10x+2=-8x-8
+10x. +10x
2=2x-8
+8
10=2x
Then divide both sides by 2
X=5
The volume of a triangular prism is found with the formula
volume = 1/2 L × w × h
So for your problem...
1/2 (15 × 12 × 8) =
1/2 (1440) =
720 cm^3
