Answer:
B
Step-by-step explanation:
Hotter = Temperature goes up
Colder = Temperature goes down
Since it's getting cooler outside, temperature drops
20°C - 22°C= -2°C
Answer: 1/8, 0.13, 1/2, 7/8
Step-by-step explanation: Mental Math
Answer:
9.6 square inches.
Step-by-step explanation:
We are given that ΔBAC is similar to ΔEDF, and that the area of ΔBAC is 15 inches. And we want to determine the area of ΔDEF.
First, find the scale factor <em>k</em> from ΔBAC to ΔDEF:

Solve for the scale factor <em>k: </em>
<em />
<em />
<em />
Recall that to scale areas, we square the scale factor.
In other words, since the scale factor for sides from ΔBAC to ΔDEF is 4/5, the scale factor for its area will be (4/5)² or 16/25.
Hence, the area of ΔEDF is:

In conclusion, the area of ΔEDF is 9.6 square inches.
<span>A) The data is skewed left and shows that on half of the days, Darren received 11 or 12 e-mails from the customer.</span>
Answer:
A
Step-by-step explanation:
Given 2 similar figures with sides in the ratio a : b
Then the ratio of their areas is a² : b²
Hence
ratio of sides = 2 : 9, then
ratio of areas = 2² : 9² = 4 : 81 → A
