The ratio of the surface areas of two similar solids can be computed by squaring the given ratio of the corresponding sides. For this given,
r = (5:1)^1
r = 25:1
Thus, the ratio of the surface areas of the similar solids is 25:1.
Answer:
360 degrees
Step-by-step explanation:
The sum of all interior angles in a quadrilateral is 360 degrees.
Answer:
5/7
Step-by-step explanation:
It says the sum, which hints that the two numbers will be added
So we can start the equation with 10+(1/3n)
we are then told they add up to 25
So they will equal 25
So the equation is
10+(1/3n)=25
Answer:
1) 24
2) 36
3) 144
Step-by-step explanation:
Order of operations are the operations in which you must complete multiple-operation equations.
Here's an acronym to help you remember the order of operations.
PEMDAS:
- Exponentiation (exponents)
----------------------------------------------------------------------------------------------------------------
7 × 3 + (18 - 9) ÷ 3
First, as stated by the order of operations, solve what is in parenthesis.
7 × 3 + (18 - 9) ÷ 3
7 × 3 + 9 ÷ 3
-------------------------------------------------------------------------------------------------------------
There are no exponents.
Further, we solve the multiplication problem(s).
7 × 3 + 9 ÷ 3
21 + 9 ÷ 3
-------------------------------------------------------------------------------------------------------------
Moreover, we solve the division problem(s).
21 + 9 ÷ 3
21 + 3
-------------------------------------------------------------------------------------------------------------
Lastly, we solve the remaining addition problem(s).
21 + 3
24
-------------------------------------------------------------------------------------------------------------
Now, we solve the remaining equations using order of operations (PEMDAS).
(7 × 3) + (18 - 9 ÷ 3)
21 + (18 - 9 ÷ 3)
21 + 18 - 3
39 - 3
36
-------------------------------------------------------------------------------------------------------------
7 × (3 + 18) - 9 ÷ 3
7 × 21 - 9 ÷ 3
147 - 9 ÷ 3
147 - 3
144
