Answer:
455.1 cm²
Step-by-step explanation:
The two containers have the following;
<u>Large container</u>
Volume : 3456 cm³
Surface area : 1024 cm²
<u>Small container</u>
Volume : 1458 cm³
Surface area : ?
If the two containers are mathematically similar then first find the volume scale factor
Volume of large/ volume of small
3456/1024 = 3.375
Length scale factor will be cube root of volume scale factor
∛3.375 = 1.5
Area scale factor is a square of the length scale factor
=1.5² = 2.25
=Surface area of the small container will be :
Larger area = 2.25 * small area
1024 = 2.25 * small area
1024/2.25 = small area
Surface area of the smaller container 455.1 cm².
<h3>Answer</h3>
c. a = 3√2, b = 6√2
<h3 /><h3>Explanation</h3>
#1.First, you find the opposite of the left triangle using sin formula
#2.After you get the opposite, find the b using sin formula and a using tan formula
<h3>Known</h3>
•Right triangle
Hypotenuse = 6
Adjacent = ?
Opposite = ?
• Left triangle
Hypotenuse = b
Adjacent = a
Opposite = ?
<h3>Question</h3>
a. adjacent of right triangle
b. hypothenuse of left triangle
<h3>Way to do</h3>
#1. Sin(∅)= opposite/hypotenuse
sin(45) = opposite/6
opposite = sin(45) × 6
opposite = 3√2
#2. a. tan(∅) = opposite/adjacent
tan(30) = 3√2 / a
a = 3√2 : tan(30)
a = 3√6
b. sin(∅) = opposite/hypotenuse
sin(30) = 3√2 / b
b = 3√2 : sin(30)
b = 6√2
#and so the a = 3√2 and b = 6√2
#you are welcome

Answer:
2%
Step-by-step explanation:
15.7 is 2% of 785
Hope this helps :)
Subtract 430 and 512 and turn into a percent
82%
Than 430+512is942
Divide by 82%is11.487804
Skip a few times until u reach 11.48
Add 4+8 and then dvd:1 dvd to buy
So 4+8is12 plus 11 is 23 and one dvd it’s 24
So the answe is 24%
