Answer:
1. -370
2. 70
3. 10.75
4. 6700
5. 37.26
Step-by-step explanation:
1. Estimating the solution means round the numbers to the nearest ten, then subtract the rounded numbers.
2. Same thing as #1
3. Using long division, it should be quite easy. If you need more evaluation, comment and I'll answer.
4. To the nearest hundred, you write the closest exact hundred. example: 8334 would be rounded to 8300.
5. To the nearest hundredth, you write the closest exact hundredth. example: 65.734 would be rounded to 65.73
Hope this helped, good luck!
X would be the number of years between 1920 and 1980:
1980-1920 = 60 years.
Replace x with 60 and solve:
Y = 0.34(60) + 44.63
Y = 20.4 + 44.63
Y = 65.03
Answer: 65.03 meters
Answer:
y = 3x +18
Step-by-step explanation:
Answer:

Step-by-step explanation:

Multiply both sides of the equation by 99, the least common multiple of 9,39,3.
m + 6 =21
Subtract 6 from both sides.
m = 21 - 6
Subtract 6 from 21 to get 15.
m=15
Answer:
<h2>35°</h2>
Step-by-step explanation:
The diagram is shown in the image attached.
A tangent is a line that intercepts at one unique point. When we have a tangent about a circle, an important results is that the tangent is perpendicular to the radius, because a radius can be seen as perpendicular to any point of the circle.
That means, the triangle formed ADC is a right triangle, because
.
Now, we know that
and
, which are leg and hypothenuse, respectively.
So, to find
we just need to use trigonometric reasons, specifically, the cosine funtion, because it relates the adjacent leg and the hypothenuse.

Therefore, the measure of angle C is 35°, approximately.
