$35.5\% = 0.355 \\ x \times 0.355 = 14.2 \\ x = 14.2 \div 0.355 \\ x = 40$
So, 14.2 is 35.5% of 40.
That's My Answer..

Simplify a^2-3a2 a^3-8a^2+12a to lowest terms

inn [45]

Answer:

$\frac{a-3}{(a-2)(a-6)}$

Step-by-step explanation:

$a^{2}-3a$ has the common multiple of a. If you factor it out, you get $a(a-3)$ .

$a^3-8a^2+12a$ also has a common multiple of a. Once factored, you get $a(a^2-8a+12)$ . This equation can be further factored to get $(a-2)(a-6)$ .

Put these two expressions over one another and you get $\frac{a-3}{(a-2)(a-6)}$ .

solniwko [45]

Answer:

Bola is 8 years old.

Step-by-step explanation:

Let Bola's age be x

Dada's age be y

Ayo's age be z

If the sum of ages of Bola, Dada and Ayo is 32 years, then;

x + y + z = 32

If they share a sum of money in ratio of their ages, then the ratio of their ages will be x : y : z

Also if Bola gets N400, Dada get-N400 and Ayo get N800, then the total amount of money shared will be expressed as:

T = 400 + 400 + 800

T = N1600

Next is to get the age of Bola

$\frac{age \ of \ bola}{32}* Total \ amount \ shared = Bola's \ Share$

Substitute the required variables and values into the formula;

$\frac{x}{32}*1600= 400\\50x=400\\x=\frac{400}{50}\\x=8$

This shows that Bola is 8 years old

The domain of the function f(x)=3x-6/x is {-3, -1, 2, 4, 5}. What is the function's range?

Maslowich

f(x)=[3x-6]/x is {-3, -1, 2, 4, 5}

 f(-3)=[3(-3) -6]]/-3 = -15/-3 = 5
f(-1)=[3(-1) -6]]/-1= -9/-1 = 9
f(2)=[3(2) -6]]/2 = 0/2 = 0
f(4)=[3(4) -6]]/4 = 6/4 = 1.5
f(5)=[3(5) -6]]/5 = 9/5 = 1.8

answer is

c {5, 9, 0, 1.5, 1.8}
