<span>If you pull the edges of the right angle down it makes a straight line.
Therefore, the angles in a triangle add up to 180°
So, 35 + 45 = 80
Then, 180 - 80 = 100
The third angle = 100° </span>
Answer:
8
Step-by-step explanation:
Since you referred to a scale factor of 2/3, and the fact that the side of the larger figure is 3, we know that the ratio of the smaller figure to the larger figure is 2/3. We can then find that the corresponding side of the smaller figure is 8.
We'll start by changing the 14% into the decimal form by moving the decimal two places to the left. That would make 14% = 0.14.
Next, multiply all the variables together.
3000 x 0.14 x 6= 2520
This shows that they'll earn $2520 within 6 years at 14% interest.
With the $3,000 principal and add the interest earned $2520
3000 + 2520 = 5520
At the end of 6 years, there will be $5,520 in the account.
Answer:
Gabriella's average original speed was 56
Step-by-step explanation:
Let's use the equation that defines the average speed "v" of Gabriella during the time (t) that her trip took:
Next let's write a similar average speed equation for the case in which she drove at (v - 7 mi/h) during the same time "t" and covered 350 miles:
Notice that the time "t" in the denominator appears equally in both equations we wrote, so let's isolate them on the right:
now equal both expression since they both share the same value on the right, and solve for the unknown "v":
