Answer:

The answer is 19.25

Step-by-step explanation:

<u>Key skills needed: Fraction operations, decimal conversion</u>

1) We are given the hint to use 9 as "b", and we get:

---> a = \frac{16}{8}(9) + \frac{10}{8}  

Let's do  \frac{16}{8}(9)

--> \frac{16}{8} is the same as 16 ÷ 8

16 divide by 8 is 2.

2) This means that it would be  ---> 2(9)  which is simply 2 times 9.

2 times 9 = 9 + 9 = 18

3) With that result, it would be  ---> a = 18 + \frac{10}{8}

Now, do \frac{10}{8} (10 divided by 8)  ---> Get 1.25

4) 18 + 1.25 = 19.25, so --> a = 19.25 is the answer

The battery standby duration (in hours) of a new model of cell phone is known to be normally distributed. Ten pieces of such new
Stells [14]

x = number of hours

want to find probability (P) x >= 13

x is N(14,1) transform to N(0,1) using z = (x - mean) / standard deviation so can look up probability using standard normal probability table.

P(x >= 13) = P( z > (13 - 14)/1) = P(z > -1) = 1 - P(z < -1) = 1 - 0.1587 = 0.8413

To convert that to percentage, multiply 100, to get 84.13%

Which expression gives the distance between the points (4,6) and (7,-3)
defon

Answer:

D = 9.4868

Step-by-step explanation:

The expression is the following

D = √((x2-x1)^2+(y2-y1)^2)

Where

(x1,y1) = (4,6)

(x2,y2) = (7,-3)

D = √((7-4)^2+(-3-6)^2)

D = √((3)^2+(-9)^2)

D = √(9+81)

D = √(90)

D = 9.4868

A multi-layer cake is in the shape of a right cylinder. The height of the cake is 20 centimeters, and its radius is 10 cm. If ea
gizmo_the_mogwai [7]

Answer:

There are total 5 layers.

Step-by-step explanation:

A multi-layer cake is in the shape of a right cylinder.

Height of the cake is = 20 cm

Radius is = 10 cm

Each of the cake layers has a volume of approximately 1,250 cm³.

Means, the volume of 1 cylindrical layer is 1250 cubic cm with radius as 10 cm and we have to find the height.

Volume of the cylinder is given as:

V=\pi r^{2} h

1250=3.14\times(10)^{2}\times h

1250=314 h

h=\frac{1250}{314}

h = 3.98 or approximately height of 1 layer is 4 cm.

As the cake's height is 20 cm so, there are \frac{20}{4}=5 layers in the cake.

Answer: There are 5 layers in the cake.
