Answer:
<h3>
m∠D = 80°</h3>
Step-by-step explanation:
In similar triangles corresponding angles have the same measure.
First, 1950m=1.95km, as 1000m=1km.
Then, 2.5-1.95=0.55km
0.55km = 550m
Given the equation:
since both bases are 6, we can equate both exponents to get the following equation:
solving for x, we get:
therefore, the solution of the equation is x = 4
<h3>
Answer: Choice C) $1125</h3>
==============================================================
Explanation:
We'll add up the values in the bottom row of the table.
A value like +150 is the same as simply saying 150
The negatives stick around.
Adding up the values in that row gets us
150 + (-50) + 400 + 300 + (-175) + (-250) = 375
This indicates that over the entire 6 month period, the overall change is +375
---------
In other words, the initial investment (call it x) has increased by 375 dollars over the 6 month period.
We can then say:
x + 375 = 1500
x = 1500-375
x = 1125
She initially invested $1125
