The length of the box would be 15 inches.
The equation would be 360= 8(4)(h)
360=24h
360/24
h=15 inches
In the number 157,562, the one is in the hundred-thousand place.
Answer:
14.54
Step-by-step explanation:
In a <em>weighted average</em> a “weight” is associated to each value.
The weighted mean is computed the following way:
Suppose you want to calculate the weighted mean of the values
a1, a1, …, an
with weights
w1, w2,..., wn
Then
<em>Weighted mean</em> =(w1*a1+w2*a2+... +wn*an)/(w1+w2+...+wn)
In this case we have
a1= 12, w1 = 8
a2 = 13, w2 = 6
a3 = 17, w3 = 12
<u>Weighted mean </u>
(12*8+13*6+17*12)/(8+6+12) = 14.54 rounded to 2 decimal places.
12 ten thousands is the answer to your question.
Answer:
Cost of the binder = $5
Cost of the highlighter = $2.5
Cost of the folder = $2
Step-by-step explanation:
Let
Cost of the binder = x
Cost of the highlighter = 1/2x
Cost of the folder = x - 3
Total cost = $9.50
Total cost = Cost of the binder + Cost of the highlighter + Cost of the folder
9.50 = (x) + (1/2x) + (x-3)
9.50 = x + 1/2x + x - 3
9.50 + 3 = x + 1/2x + x
12.50 = 2x + 1/2x
12.50 = 2 1/2x
12.50 = 5/2x
x = 12.50 ÷ 5/2
= 12.50 × 2/5
= 25/5
x = $5
Cost of the binder = x = $5
Cost of the highlighter = 1/2x = 1/2*6 = $2.5
Cost of the folder = x - 3
= 5 - 3 = $2
