Answer: D $10.84
Step-by-step explanation:
If the box is a cube and paper is needed to wrap it, then we need to find the surface area of the box then multiply it buy the cost of the wrapping paper.
The surface area of a cube uses the formula 6a^2 where a is any side length.
We know that the box has a side length of 8.5 inches.
SA = 6*8.5^2
SA= 433.5
Now multiply the surface area by the money.
433.5 * 0.025 = 10.8375
Round 10.8375 to dollars and cents as it is required.
10.8375 = 10.84
Which means it will cost $10.84 to wrap the box.
Answer:
824.05
Step-by-step explanation:
the hundreths place is two spots behind the decimal, there is a four. Look at the number next to it is a 7 so you round up
Answer:
x <-12
Step-by-step explanation:
-1/2x > 6
Multiply each side by-2. This will flip the inequality
-2 *-1/2x < 6*-2
x <-12

Step-by-step explanation:
Answer:
1. The scale factor here is 1.5
2. The scale factor here is 2/3
Step-by-step explanation:
Here, we shall be dealing with scales of triangles.
we have two triangles;
ABC and DEF
longest sides are in the ratio;
12 : 8
1. What scale factor translates DEF to ABC?
The ratio of the length can be beaten down to 3:2
So therefore, we can see that by multiplying the sides of of DEF by 1.5, we can arrive at the sides of ABC
So the scale factor here is 1.5
2. This is like the other way round of what we have above.
By multiplying the sides of ABC by 2/3, we shall have the sides of DEF
