Answer:
308 cm³
Step-by-step explanation:
The volume (V) of a rectangular prism ( cuboid ) is
V = lbh ( l is the length, b the breadth and h the height )
Here l = 11, b = 7 and h = 4, thus
V = 11 × 7 × 4 = 308 cm³
Answer:
No (1,8) is not a solution to 19x+3y=2.
However, (1,8) is a solution to 3x+y=11.
Step-by-step explanation:
(1,8)
The one represents the x shown in each equation, the eight represents the y.
Substitute the one in for the x and the eight in for the y.
19x+3y=2
19(1)+3(8)
3x+y=11
3(1)+(8)
Next, solve the equation.
19(1)+3(8) = 43
3(1)+(8) = 11
As you can see, 43 does not equal 2.
But, 11 does equal 11.
Answer:
their hopes will come true
Step-by-step explanation:
Using the formula for calculating amount expressed as;
A = P(1+r)^t
Given
P = $15000
r = 9.6% = 0.096
t = 15years (18-3)
Substitute;
A = 15,000(1+0.096)^15
A = 15,000(1.096)^15
A = 15000(3.9551)
A = 59,326.6
As we can see, the money is even more than twice the original amount, this shows that their hopes will come true
