GPT-4o mini · Answer

To find the distance from the basement floor at -16 feet to the roof at 37 feet, we need to calculate the difference in elevation between these two points.

The elevation of the basement floor is -16 feet, and the elevation of the roof is 37 feet. The distance can be determined by subtracting the basement elevation from the roof elevation:

\[ \text{Distance} = \text{Roof Elevation} - \text{Basement Elevation} \] \[ \text{Distance} = 37 - (-16) \] \[ \text{Distance} = 37 + 16 \] \[ \text{Distance} = 53 \text{ feet} \]

Thus, the distance from the basement floor to the roof is 53 feet.

The correct response is:

53

Simplify the expression. −8.5−(−3.7)= Desmos Scientific Calculator (1 point) Responses 12.2 12.2 -12.2 -12.2 4.8 4.8 -4.8

GPT-4o mini · Answer

To simplify the expression $-8.5 - (-3.7)$, we first need to recognize that subtracting a negative number is equivalent to adding the positive version of that number: $$ -8.5 - (-3.7) = -8.5 + 3.7 $$ Now, we perform the addition: $$ -8.5 + 3.7 $$ If we think of it on a number line, moving 3.7 units to the right from -8.5: 1. The first step is to find the total: $$ -8.5 + 3.7 = -4.8 $$ Thus, the simplified expression is: $-4.8$ The correct response is: -4.8

GPT-4o mini · Answer

To simplify the expression $25 - (-80)$, we recognize that subtracting a negative number is equivalent to adding the positive version of that number: $$ 25 - (-80) = 25 + 80 $$ Now, we can perform the addition: $$ 25 + 80 = 105 $$ Thus, the simplified expression is: **105** The correct response is: 105

Simplify the expression. −18.5−17.5 Desmos Scientific Calculator (1 point) Responses 36 36 -36 -36 1 1 -1

GPT-4o mini · Answer

To simplify the expression $-18.5 - 17.5$, we can combine the two negative numbers: $$ -18.5 - 17.5 = -(18.5 + 17.5) $$ Now we can add the two values: $$ 18.5 + 17.5 = 36 $$ Therefore, we have: $$ -18.5 - 17.5 = -36 $$ Thus, the simplified expression is: $-36$ The correct response is: -36
