Using rounding to estimate the solution to the problem. 538-714 Be sure to give the estimated solution, not the exact solution.
amid [387]

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!

meriva

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

Solve for the m in the equation
velikii [3]

Answer:

m = 15

Step-by-step explanation:

\frac{m}{9 }  +  \frac{2}{3}   =  \frac{7}{3}

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

In the diagram shown on circle A, segment CD is tangent to the circle at point D. If CD=23 and CA = 28.
gladu [14]

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 \angle D= 90\°.

Now, we know that CD=23 and CA=28, which are leg and hypothenuse, respectively.

So, to find m \angle C we just need to use trigonometric reasons, specifically, the cosine funtion, because it relates the adjacent leg and the hypothenuse.

cos(C)=\frac{CD}{CA}=\frac{23}{28}  \\C=cos^{-1}(\frac{23}{28} ) \approx 35 \°

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