Answer:
9
Step-by-step explanation:
Given that the sample size is 45 blocks
Let number of red blocks in the bag to be x
Then the probability of chosing a red block will be x/45
Given that the probability of choosing a red block is 1/5 then you can form the expression;
x/45 = 1/5 ---------------find the value of x by performing cross multiplication
5x=45*1
5x/5=45/5
x=9

Answer:
55°
Step-by-step explanation:
A triangle always has 180° and if we know 2 angles we can just subtract those 2 angles from 180 to find the last angle, which is 55
Hint: The rule of the 45-45-90 triangle is that both sides are x and the hypotenuse is x√2.
x = 5√2
To find the hypotenuse you multiply x by √2.
5√2 (√2)
5√4
5 (2)
10
The hypotenuse is 10.
