First way: 1 doubled is 1+1, which is 2. 2 increased by 10 equals 12.
Second way: 1 doubled is 1*2, which equals 2. 2 increased by 10 equals 12.
Answer:
13 cars per hour
Step-by-step explanation:
She can vacuum 104 cars in 8 hours, so divide 104 by 8, 104/8, to get 13. So she can vacuum 13 cars in 1 hour.
Answer:
67.5
Step-by-step explanation:0.5*9*15= 67.5 cm squared
Answer:
88 Feet Per Second
Step-by-step explanation:
Firstly you need to know 3 things:
> 60 mph = 60 Miles Per Hour
> 1 Hour = 60 mins = 60*60 = 3600 seconds
> 1 Mile = 5280 feet
Next you can change the miles to feet and hours to seconds.
60 mi/ 1 hour = 60*5280/ 3600 = 316800ft/ 3600sec
Now time to reduce that big fraction! (Or in this case just divide by 3600 sec)
316800ft/ 3600sec
= 88ft/1sec
= 88 Feet Per Second
Hope that helps!
Angle m∠8 =41° and x=10°
Step-by-step explanation:
Given that m∠3=139° then
m∠3=m∠1 = corresponding angles = 139° and m∠7=m∠5=m∠3=139°
m∠8= 180°-139° =41° -sum of angles on a straight line
m∠8=m∠6=m∠4=m∠2= 41°
2.
Given that m∠3=8x+70° and m∠8=4x-10° then you can find the value of x as;
m∠3+m∠8=180°
8x+70°+4x-10°=180°
12x+60°=180°
12x=180°-60°
12x=120°
12x/12 =120°/12
x=10°
Hence,
m∠3=8x+70° = 8*10 +70° = 80°+70°=150°
m∠8= 4x-10° = 4*10 - 10° = 40°-10° =30°
m∠1 =m∠3 = m∠5 = m∠7 =150°
m∠2 = m∠ 4 = m∠6 = m∠8 =30°
