Well the formula for area is A=LxW where L=length and W=width
so A=2.5(1) but this in inches so convert to feet
half inch=15 ft so 2.5 inches=
(15)=5(15)=75 ft
half inch=15 ft so 1 inch=2(15)=30ft
Now we can rewrite our area equation: A=(75ft)(30ft)=2250 ft²
For 13. the answer is w = -1.
Here are the steps
1. subtract 5 from both sides ( 3w = 2 - 5)
2. simplify 2 - 5 to -3 (3w = -3)
3. divide both sides by 3 ( finally the answer is w = -1.
)
Answer:
B. 5
Step-by-step explanation:
Answer: 212 feet
Have a look at the image shown below. On that image, I've marked key details to focus on. Namely, the bottom right triangle has the angle CAB equal to 27 degrees because of the congruent alternate interior angles. This is the reference angle we'll base everything off of.
Opposite this angle is the side BC = 108 which is the lighthouse height. Adjacent to this angle is AB = x which is unknown. The goal is to solve for x
Use the tangent rule
tan(angle) = opposite/adjacent
tan(angle CAB) = CB/AB
tan(27) = 108/x <--- substitution
x*tan(27) = 108 <--- multiply both sides by x
x = 108/tan(27) <--- divide both sides by tan(27)
x = 211.96 <-- see note below
x = 212
note: use a calculator that has the trig functions sine, cosine, etc. You'll use the tan function for tangent. Make sure your calculator is in degree mode. the result you get is approximate as shown above, which will round to 212 when rounding to the nearest whole number.

Answer: 6 cm^3</h3>
This is the same as saying 6 cubic cm
====================================================
Work Shown:
d = density = 4 g/cm^3
m = mass = 24 g
v = volume = unknown
--------------
d = m/v
4 = 24/v
4v = 24 .... multiply both sides by v
v = 24/4 .... divide both sides by 4
v = 6 cm^3
