answer:
11
step-by-step explanation:
first, let us turn 8 1/4 and 3/4 into decimals-
1÷4
= 0.25
3÷4
= 0.75
8.25÷0.75
=11
good luck :)
i hope this helps
brainliest would be highly appreciated
have a nice day!

Conclusion:
Step-by-step explanation:
Given
Two similar quadrilaterals
To determine
x, y, and z
Given that the two quadrilaterals are similar,
so their corresponding ratios will be:
x/10 = 5/4
x = 5/4 × 10
x = 50/4
x = 25/2
x = 12.5
Thus, the value of x = 12.5
To determine the value of y, the corresponding ratio such as
y/4 = 8/10
y = 8/10 × 4
y = 32/10
y = 16/5
y = 3.2
Thus, the value of y = 3.2
To determine the value of z, the corresponding ratio such as
z/5 = 15/x
as x = 12.5, so substitute x = 12.5
z/5 = 15/12.5
z = 15/12.5 × 5
z = 75/12.5
z = 6
Therefore, the value of z = 6

Answer:
A prime number is a natural number greater than 1 that is not a product of two smaller natural numbers.
Answer:
a) X ~
b) μ = 100/3
c)
d) A battery is expected to last 100/3 months (33 months and 10 days approximately).
e) For seven batteries, i would expect them to last 700/3 months (approximately 19 years, 5 months and 10 days).
Step-by-step explanation:
a) The life of a battery is usually modeled with an exponential distribution X ~
b) The mean of X is μ = 1/0.03 = 100/3
c) The standard deviation is
d) The expected value of the bateery life is equal to its mean, hence it is 100/3 months.
e) The expected value of 7 (independent) batteries is the sum of the expected values of each one, hence it is 7*100/3 = 700/3 months.
