Do you know how many marbles are in the box?
B) is the correct answer hope this helps :D
Area of the rectangle is given by formula
Area = length * width
Then area of bed having dimension 2.78feet by 4.81feet will be:
Area1= 2.78*4.81 = 13.3718 square feet.
Area of bed having dimension 2.78feet by 5.61feet will be:
Area2= 2.78*5.61 = 15.5958 square feet.
Now add both areas to find total area
Total area = 13.3718 +15.5958 = 28.9676
We have to find which choice does NOT represent the total area.
Choices are not given so you just have to pick choice which is not same as 28.9676 square feet.
Isn’t it the same degree as BAC
By definition, we have to:
Where,
t: time
d: distance
v: speed
Let's define the following variable:
v: Grace's speed
We write the equation that models the problem:
From here, we clear v.
We have then:
Substituting values we have:
Answer:
Grace drives at a rate of 56 miles per hour.
