X___ -_____ X____ X_____ +_____
$28.8 $18.8 225.6 $56.4 $282
You multiply $7.20 by the 4 hours she's working and you'll get $28.80. Then you would subtract the $10 from your answer and get $18.80. Then you'd multiply $18.80 by 12 for the mouths she's working and get $225.60. Next you multiply $225.60 by .25 from the grandparents and get $56.40. Finally you add $225.60 to $56.40 and get $282 in her savings account.
Answer:
46.125 or 46 1/8
Step-by-step explanation:
2(3×8-15÷16)
=2(24-15÷16)
= 48 - 30/16
= (768 - 30)/16
= 738/16
= 46.125 or 46 1/8
A rational number can be expressed in the form a/b, where a and b are other integers. To satisfy this definition, 0.9 can be written as 9/10, 18/20, 90/100, etc.
Answer: (-2)(4)
Step-by-step explanation:
The model could be explained as follows ;
Step 1 : 0 - - - - > - 2 = - 2 units
Step 2 : -2 - - - - > -4 = - 2 units
Step 3: - 4 - - - - > -6 = - 2 units
Step 4: - 6 - - - - > -8 = - 2 units
-2 units for reach of the 4 steps
Therefore, model is expressed as :
(-2) × 4
(-2)(4)
Kindly view detailed sketch and explanation in the picture attached.
Step-by-step explanation:
1.Assuming the same sample size and considering the same value for the errors ( not taking into consideration the type of music, the volume of the sound and cow familiar the runner is with that type of stimuli, age group, time of the day/ number of days, running conditions like wether and equipment, distance) one can state:
A. Music has no influence over the running speed ( when jogging) in Washington DC
B.When listening to music, people ( in Washington DC) run faster while jogging
The mean running speed is a simple, ponderate or other type of mean ( that takes into consideration the variations of speed at the beginning and by the end of the race?
