Answer:
1st Picture: m∠RPS= 15° m∠QPR=25°
2nd Picture: x= 53°
Step-by-step explanation:
1st Picture:
8x+7+9x+16=40
17x+23=40
17x=40-23
17x=17
x=1
Substitute the x values with 1 and solve.
Answer:
Option C. 6
Step-by-step explanation:
we know that
If NM bisects the angle ENL
then
∠MNL=∠MNE
In the right triangle MLN
sin(∠MNL)=ML/MN -----> equation A
In the right triangle MEN
sin(∠MNE)=6/MN -----> equation B
equate equation A and equation B
ML/MN=6/MN
Simplify
ML=6
Answer:
20%
Step-by-step explanation:
6.25 times 20% or 0.2 = 1.25. therefore she tipped the sever 20% of the total cost of her meal.
Given:
μ=106.3 minutes
σ=18.5 minutes
Need to find
P(80<x<95)=>
P(x)=Z((95-μ)/σ)-Z((80-μ)/σ)
=Z(-0.61081)-Z(-1.42162)
=0.27066-0.077568
=0.1931
Therefore probability of customers waiting between 80 and 95 minutes is 0.1931
It would be a scalene triangle as all angles are different
