A ratio reads left to right and can be written in 3 different ways. for example, 3:5, 3 to 5, or 3/5
if you have a problem that says something like: for every 3 people there is 1 child, the ratio is 3 to 1. Hope this was helpful in in 6th grade too and in advanced math!
Answer:
d/c = 8
Step-by-step explanation:
f(x) = 5.4321×2^×
f(4) = 5.4321×2^4 = d
f(1) = 5.4321×2^1 = c
d/c = (5.4321×2^4)/(5.4321×2^1) = 2^3 = 8
Answer:
(B)The GCF of the numbers(28 and 36) in each term in the expression is 4.
(C)The GCF of the variables(a and ab) in each term in the expression is a.
(E)The factored form of the expression is 4a(7+9b)
Step-by-step explanation:
Given the expression: 
If we write it as a product, we obtain:
We can see the following
- The GCF of the numbers(28 and 36) in each term in the expression is 4.
- The GCF of the variables(a and ab) in each term in the expression is a.
- The factored form of the expression is 4a(7+9b)
The correct options are B, C, and E.
Answer: -2a^3 + 9a^2 + 45a + 18b^2 + 6ab^2
Step-by-step explanation:
(a + 3) * (-2a^2 + 15a + 6b^2)
We open the brackets with (a + 3)
a ( -2a^2 + 15a + 6b^2) + 3(-2a^2 + 15a + 6b^2)
Opening the brackets
= a * -2a^2 = -2a^3
a * 15a = 15a^2
a * 6b^2 = 6ab^2
3 * -2a^2 = -6a^2
3 * 15a = 45a
3 * 6b^2 = 18b^2
Let's arrange those values weve gotten together ,don't forget the signs each carry
= -2a^3 + 15a^2 + 6ab^2 - 6a^2 + 45a + 18b^2
Collect the like terms
= -2a^3 + 15a^2 - 6a^2 + 6ab^2 + 45a + 18b^2
= -2a^3 + 9a^2 + 6ab^2 + 45a + 18b^2
5.46 ÷ 3 = 1.82
1.82 x 5 = 9.1
The answer is "9.10"
