Answer:
6
Step-by-step explanation: 4^2 - 8 / (1+3) x 5 = 4^2 - 8 / 4 x 5 = 16 - 8 / 4 x 5 = 16 - 2 x 5 = 16 - 10 = 6
The volume of the pyramid is 94.5
Answer:
y = 4(3)^x
Step-by-step explanation:
Here, we want to write the exponential equation
From the question, we have the equation tripling in x value every year and the original amount is 4
The exponential equation is of the form;
y = a(b)^n
In this case;
a = 4 , b = 3 and n = x
So we have the equation as;
y = 4(3)^x
Answer:

Step-by-step explanation:
Answer:
55
Step-by-step explanation:
The first crayon is chosen out of 11,so there are 11 choices
11
The second crayon is chosen out of 10 crayons left so there are 10 choices
10
11*10 = 110
But we do not care about the order, so we divide by 2 since there are 2 places
110/2 =55
