This would be the same as the last question you posted!
If t₀ is the initial temperature of the metal then after time t hours the temperature will be t₀-5t, which must not go below -75℃.
So t₀-5t≥-75.
(1 3/4) / (1/5) =
(7/4) / (1/5) =
7/4 * 5/1 =
35/4 or 8 3/4 <===
To get this, lets begin by looking at the known.
In total, it costed $168. Since it costs $5 per tree, lets times:
5x8= 40
Now that we know that delivery fees were $40, lets subtracted that from the total.
168-40=128
That means our total now without delivery fees is $128.
Since we know that Yuri bought 8 trees, we can divide by that.
128/8=16.
Meaning each tree costs $16
Answer:
89.132 inch
Step-by-step explanation:
“this shape is made up of one half-circle attached to a square with side lengths 16 inches. You can use 3.14 as an approximation.”
so, the square has a perimeter of 16 inch, four sides that will be 64 inch
then the half circle rule of perimeter of half circle: πr + 2r
=> perimeter of semicircle = π * 8 +2 * 8 = 41.132 inch
<em>without the bottom line of half circle= 41.132 -16 = 25.133 inch</em>
<em />
So total 25.133 + 64 =89.132 inch
have a great day and nc question
