Answer:
The answer is 60.
Step-by-step explanation:
÷![\frac{4}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B5%7D)
Now, apply the fraction rule(\frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}):
×![\frac{5}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B4%7D)
Cross-cancel(common factor of 4):
×![\frac{5}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B1%7D)
Multiply:
![\frac{12 x 5}{1 x 1}](https://tex.z-dn.net/?f=%5Cfrac%7B12%20x%205%7D%7B1%20x%201%7D)
Simplify:
12 x 5=60
The answer is 60
hope this helps :)
The steps matter on the size of the number.
Answer:
60 square units; 40 units
Step-by-step explanation:
to find the missing side you use the pythagorean theorem
a^2 + b^2 = c^2
8^2 + b^2 = 17^2
64 + b^2 = 289
b^2 = 225
b = 15
area is l*h*1/2
15 * 8 * 1/2 = 60 square units
perimeter is adding them all
15 + 8 + 17 = 40 units
Answer:
probability the spy is able to unlock the tablet on his first try.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Desired outcomes:
1 correct password, so ![D = 1](https://tex.z-dn.net/?f=D%20%3D%201)
Total outcomes:
Nine-digit codes.
For each digit, there are 10 possible outcomes. So
![T = 10^9](https://tex.z-dn.net/?f=T%20%3D%2010%5E9)
What is the probability the spy is able to unlock the tablet on his first try?
![p = \frac{D}{T} = \frac{1}{10^9}](https://tex.z-dn.net/?f=p%20%3D%20%5Cfrac%7BD%7D%7BT%7D%20%3D%20%5Cfrac%7B1%7D%7B10%5E9%7D)
probability the spy is able to unlock the tablet on his first try.
