Answer:
(120 + 12.5pi) ft^2
Step-by-step explanation:
10ft x 12 ft = 120ft^2
10ft/2 = 5 ft (Radius)
Area of semi circle:

The top of the cake to be triangular with one side length 10cm, one side length 12cm and a 90-degree angle between these sides
Answer:
See attachment
Step-by-step explanation:
Given
[tex]Side\ 1 = 10cm[/tex]
[tex]Side\ 2 = 12cm[/tex]
[tex]\theta = 90^\circ[/tex]
Required [Missing from the question]
Draw the top of the cake
See attachment for reference.
From the attachment,
[tex]2cm = 1\ unit[/tex]
So:
[tex]Side\ 1 = 10cm[/tex]
[tex]Side\ 1 = 5 * 2cm[/tex]
Substitute [tex]2cm = 1\ unit[/tex]
[tex]Side\ 1 = 5 * 1unit[/tex]
[tex]Side\ 1 = 5\ units[/tex]
[tex]Side\ 2 = 12cm[/tex]
[tex]Side\ 2 = 6 * 2cm[/tex]
Substitute [tex]2cm = 1\ unit[/tex]
[tex]Side\ 2 = 6 * 1unit[/tex]
[tex]Side\ 2 = 6\ units[/tex]
This means that, the given side lengths will be represented by 5 units and 6 units on the grid, respectively.

6) The cost of a computer system increases with increased processor speeds. The cost C
of a system as a function of processor speed is estimated as C = 1234 - 35 + 1900,
where S is the processor speed in MHz. Find the processor speed for which cost is at a
minimum. [4 marks]
Answer:
The speed is: 0.0142MHz
Step-by-step explanation:
Given
[tex]C(s) = 1234s^2 - 35s + 1900[/tex]
Required
The processor speed when the cost is at minimum
First, differentiate C(s) with respect to s
[tex]C(s) = 1234s^2 - 35s + 1900[/tex]
[tex]C'(s) = 2468s - 35[/tex]
The cost is at minimum when [tex]C'(s) = 0[/tex]
So, we have:
[tex]C' = 2468s - 35 = 0[/tex]
[tex]2468s - 35 = 0[/tex]
Solve for s
[tex]2468s = 35[/tex]
[tex]s=\frac{35}{2468}[/tex]
[tex]s\approx0.0142[/tex]

Discuss the significance of the sample observation given that the probability of observing such a .sample estimated to be 0.0015
Answer:
The significance of the sample is that at it is statistically significant at 0.01 level ( i.e. of observing the sample < 0.01 )
Step-by-step explanation:
The sample observation which is 121 mothers that take vitamin supplements have male babies with mean weight of : 3.67 kg
while the National average birth weight = 3.39 kg
probability of observing such a sample = 0.0015
Hence the significance of the sample is that at it is statistically significant at 0.01 level ( i.e. of observing the sample < 0.01 )

A sphere has a radius of 9 feet. A second sphere has a radius of 6 feet. What is the difference of the volumes of the spheres? The volume of the larger sphere is π cubic feet greater than the volume of the smaller sphere.
Answer:
684 π
Step-by-step explanation:
volume of a sphere = (4/3) x (n) x (r^3)
n = 22/7
r = radius
volume of larger sphere
4/3 x n x 9³ = 972 n
4/3 x n x 6³ =288n
972n - 288n = 684n
