1 yard=36 inches and 126 inches to yards would be 3.5 yards because 3ft equals 36 inches and 126 divided by 36 equals 3.5 to check to 3.5 multiplied by 36
Answer:
1. 800 cm squared
2. 152 cm squared
Step-by-step explanation:
let break it down
1. 800 cm squared
20 * 7 = 140
20 * 6 = 120
38 - 20 = 18
30 * 18 = 540
now add all of them together
140 + 120 + 540
100 + 100 + 500 = 700
40 + 20 + 40 = 100
700 + 100 = 800 cm squared
2. 152 cm squared
16 * 10 = 160
2 * 2 + 2 * 2 = 4 + 4 = 8
160 - 8 = 152 cm squared
Sin A=Cos (90º-A)
Then:
sin 30º=cos (90º-30º)=Cos 60º=1/2
Answer: cos 60º=1/2
Answer: Intercept of the equation = (9,0)
Charge remaining in Lauren's battery is 0 after 9 hours( since Lauren left her house)
Step-by-step explanation:
Given: When t= the number of hours since Lauren left her house, the charge remaining in Lauren's battery, as a percentage, can be modeled by the equation B=63-7t .
To find the x-intercept, put B =0 (as x denoted the independent variable , here independent variable is 't')
Hence, the x-intercept of the equation = (9,0)
i.e. Charge remaining in Lauren's battery is 0 after 9 hours( since Lauren left her house)
My answer is B 14-6
