Answer:
56
Step-by-step explanation:
g(x)=5x+1
(gog)(2)=5(5x+1)+1
=5(5(2)+1)+1
=5(10+1)+1
=5(11)+1
=55+1
=56

Answer:
The surface area is 2,886 cm^2
Step-by-step explanation:
In this question we are asked to calculate the surface area of a rectangular octagonal prism.
The correct mathematical formula to use is as follows;
Mathematically, the surface area is
A = 8ah + 4(1+√2)•a^2
From the question, we identify the value of a as 10cm and the value of h as 24cm
We plug these two values into the equation above to yield the following;
A = 8(10)(24) + 4(1 + √2) * 10^2
A = 1,920 + 400(2.4142)
A = 1920 + 965.685
A = 2,885.69 or approximately 2,886 cm^2
Answer:
Brian initially had £30.
Step-by-step explanation:
Let Brian initially had money in his wallet = £x
and Colin had the money = £y
Since ratio of money in Brian's wallet to Colin's wallet was 5 : 1
Therefore,
⇒ x = 5y -------(1)
Brian spent £27 that day, so money left with him = £(x - 27)
After spending the money Brian had £3 less than Colin.
(x - 27) = (y - 3)
x = y + 27 - 3
x = y + 24 -------(2)
Now we equate the equations (1) and (2) for the value of x,
5y = y + 24
5y - y = 24
4y = 24
y = £6
From equation (2),
x = 6 + 24
x = £30
Therefore, Brain initially had £30.
