Answer:
m∠YOZ = 60°
Step-by-step explanation:
Because it's given that m∠VOX = 90° and m∠WOX = 30°, we can find that m∠VOW = 60°.
Using the Vertical Angles Congruence Theorem, we can identify m∠YOZ = 60° because VY and WX are intersected, meaning their vertical angles are congruent.
Answer:
27
Step-by-step explanation:
looked on photomath
Step-by-step explanation:
-2y+4>10
subtract 4 from both sides
-2y+4-4>10-4
-2y>6
divide both sides by two
-2/2y>6/2
-1y>3
if negative y is greater than three than you have to multiply both sides of the equation by -1
y>-3 if you put that back into the earlier equation it is impossible.
so we have to switch the signs to < or less than
y<-3

decrease = 9%
percent decrease =
× 100%
decrease = $98 - $89 = $9
percent decrease =
× 100% = 9% (to nearest whole percent )
Question 1: 5/8=0.625=62.5% 13/22=about 0.59(repeats 09)=9%
22/30=about 0.73(repeats 3)=73% 12/25=0.45=45%
Store 3 had the greatest percentage of smart phones.
Question 2: 0.775/7.75%=0.775/0.0775=10
For mobile phone 3, it uses o.775 hour of battery life if 7.75% of battery is used.
