Answer:13/15
Step-by-step explanation:
Add 7/9 and 2/3 the answer is 13/9 then divide it by 5/3 in order for you to divide get the reciprocal of 5/3 which is 3/5 then multiply it and you well get 13/15
Question #1:
The surface area of a prism is the area of the outside of the prism, the volume is how much the inside of the container holds.
Let's find the volume and surface area of the prism given.
V = lwh
Plug in what we know:
V = (18.4)(10.9)(8.7)
Multiply:
V = <span>1744.872 m^3
SA = </span>2<span>(<span><span><span>wl </span>+ <span>hl </span></span>+ <span>hw</span></span><span>)
Plug in what we know:
SA = 2((10.9)(18.4) + (8.7)(18.4) + (8.7)(10.9))
Multiply:
SA = 2(200.56 + 160.08 + 94.83)
Add:
SA = 2(455.47)
Multiply:
SA = 910.94 m^2
Now find the difference:
</span></span>Note that these are different measurements.
The volume is measured in cubic meters and the surface area is measured in square meters.
910.94 m^2 = 27493.793 m^3
Find the difference:
27493.793 m^3 - 1744.872 m^3 = 25748.921
Question #2:
The formula for the surface area of a rectangular prism is:
SA = 2(wl + hl + hw)
Plug in what we know:
SA = 2((5)(6) + (3)(6) + (3)(5))
This is the equation we use to find the surface area of this figure.
Multiply:
SA = 2(30 + 18 + 15)
Add:
SA = 2(63)
Multiply:
SA = 126 cm^2
I hope you do not intend some sort of compounding.
Basically, 3000 per month for 40 years can be calculated by doing some simple maths. So 3000 x 12 to get for a complete year. Which is 36000. NOw we can multiply this value by 40 to get the correct amount. So that is 1440000.
Now five percent of this amount is 5 / 100 x 1440000 = 72000. So the final answer after adding 5 % would be 1512000.
Answer:
triangle is a subcategory of polygon
You subtract 2 on each side. so then it will be 2x=2. then you divide each side by 2 to get x=1.
hope this helped!
