Your answer would be D) -3°F/hour
Look at it this way...
47°F at 7:20pm
46°F at 7:40pm
45°F at 8:00pm
44°F at 8:20pm
43°F at 8:40pm
The temperature is going down by 1°F every 20 minutes so...
-1°F/20 minutes
Obviously there's no answer choice that says that so you'd need to change the minutes into an hour...
So an hour is 60 minutes and 60/20 = 3
So if you do 3・-1
You get the answer... -3°F/hour
Answer:
To convert a decimal to percent, just multiply it by 100, or move the decimal place 2 times
Ex: 0.29 x 100 = 29
The answer would be 29%
To convert a percent to a decimal, do the opposite
Ex: 29%/100 = 0.29
Answer:
The triangles aren't necessarily congruent. SAS postulate is side angle side, which means that the angle that is congruent must be between the two sides that are congruent. DF is congruent to MN, and DG is congruent to MP. This means, that angle D must be congruent to angle M.
However, we only know that D is congruent to P, not M.
These triangles are not necessarily congruent.
Answer:
(-9.5, -4)
Step-by-step explanation:
Given the ratio a:b (a to b) of two segments formed by a point of partition, and the endpoints of the original segment, we can calculate the point of partition using this formula:
.
Given two endpoints of the original segment
→ (-10, -8) [(x₁, y₁)] and (-8, 8) [(x₂, y₂)]
Along with the ratio of the two partitioned segments
→ 1 to 3 = 1:3 [a:b]
Formed by the point that partitions the original segment to create the two partitioned ones
→ (x?, y?)
We can apply this formula and understand how it was derived to figure out where the point of partition is.
Here is the substitution:
x₁ = -10
y₁ = -8
x₂ = -8
y₂ = 8
a = 1
b = 3
