Answer:
the answer is 5b^3+8
Step-by-step explanation:
Answer: $ 14
Step-by-step explanation:
Since, the cost of 1 pair of socks = x
The cost of 6 pair of socks = 6 x
Total amount spend = $ 40
According to the question,
6 x - 14 = 40
6 x = 40 + 14
6 x = 54
x = 9
Thus, the original price of one pair of socks = $ 9
⇒ The original price of 6 pairs of socks = $ 54
Hence, the total change = original price of socks - the price of socks in the sale = 54 - 40 = $ 14
Answer:
x=27°
Step-by-step explanation:
we know that
<u><em>The Triangle Exterior Angle Theorem</em></u>, states that: An exterior angle of a triangle is equal to the sum of the opposite interior angles
step 1
Find the measure of angle PLM
we know that
m∠PLM+m∠LPM=m∠PMN ----> by Triangle Exterior Angle Theorem
we have
m∠LPM=x°
m∠PMN=2x+72°
substitute
m∠PLM+x=2x+72°
m∠PLM=2x-x+72°
m∠PLM=x+72°
step 2
Find the measure of angle x
we know that
3x+m∠PLM=180° ----> by supplementary angles (form a linear pair)
we have
m∠PLM=x+72° (see step 1)
substitute
3x+x+72°=180°
4x=180°-72°
4x=108°
x=27°
#3. the probability of spinning "rock" is 25% or 1/4 so we can use this probability to predict the number of times we would expect to get "rock" in 80 spins as follows:
25% of 80 = .25(80) = 20 So how likely is it we spin 20 'rock' out of 80 spins? At 25%, not very likely..
#4.
A. True
B. True
C. False, the theoretical probability of make make using the spinner is
or about 56%
