Answer:
5/18
Step-by-step explanation:
There are two ways this can happen: you roll a 3 on the first cube and not a 3 on the second cube, or you roll not a 3 on the first cube and 3 on the second cube.
P = (1/6)(5/6) + (5/6)(1/6)
P = 5/36 + 5/36
P = 10/36
P = 5/18
Answer:
(2, 8)
Step-by-step explanation:
Given the system of equation
3x+2y=22 ... *4
-4x+3y=16 .... *3
Using the elimination method
12x + 8y = 88
-12x + 9y = 48
Add
8y + 9y = 88+48
17y = 136
y = 136/17
y = 8
Recall that
3x+2y=22
3x+2(8)=22
3x + 16 = 22
3x = 22-16
3x = 6
x = 6/3
x = 2
Hence the required solution (x, y) is (2, 8)
Answer:
The other side =
units
Step-by-step explanation:
A right triangle has a side of length
units and;
the hypotenuse is ![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
According to Pythagorean theorem,
a² + b² = c² , where a and b are the two legs of a triangle and c is the hypotenuse.
Lets say a² =
and c² = (![(\frac{1}{3} )^2](https://tex.z-dn.net/?f=%28%5Cfrac%7B1%7D%7B3%7D%20%29%5E2)
b² = c² - a²
b² =
-
= ![\frac{1}{144}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B144%7D)
So b =
=
units.
So the other side =
units.
The average in January is -36°
The average in July is 17° warmer
So add 17 to -36
The average in July is -19°C
it will be 2:30 because 12 to 3 is 3 hours and it lose 10 minots ber hour so it will he will lose 30 mins
