What is the value of m in the figure below? If necessary, round your answer to
notka56 [123]

First

\\ \sf\longmapsto BD^2=AD\times DC

\\ \sf\longmapsto BD^2=18^2+7^2

\\ \sf\longmapsto BD^2=324+49

\\ \sf\longmapsto BD^2=363

\\ \sf\longmapsto BD=\sqrt{363}

\\ \sf\longmapsto BD=19.2

Now

Using Pythagorean theorem

\\ \sf\longmapsto BD^2+CD^2=m^2

\\ \sf\longmapsto m^2=7^2+19.2^2

\\ \sf\longmapsto m^2=49+363

\\ \sf\longmapsto m^2=412

\\ \sf\longmapsto m=\sqrt{412}

\\ \sf\longmapsto m=20.3

Nearest value in options is 18

Hence option a is correct

Sean has 5 1/2 cups of grape tomatoes, if each serving is 3/4 of a cup, how many servings of grape tomatoes does Sean have
ollegr [7]

Answer:

7 servings

Step-by-step explanation:

first make 5 1/2 unsimplified, to 11/2. then multiple it by 2 so the denominator is the same as 3/4, making it 22/4. 22/3 is 7 1/4, so he has 7 full servings and 1/4th of a serving.

It took a race car driver 3 hours and 15 minutes to go 500 miles. What was his mean rate of speed, to the nearest tenth of a mil
Tresset [83]
3 x 60 (because there are 60 minutes in an hour) = 180. then 180 + 15 = 195. 500 / 195 = 2.6 miles per minute. 2.5 x 60 since its asking for miles per hour, is 156. he goes 156 miles per hour.

The population of a city is increasing at a rate of 4% each year. In 2000, there were 236,000 people in the city. Write an expon
sukhopar [10]

Answer:

A = 236,000 (1+ 0.04)^9

335,902 people in 2009

Step-by-step explanation:

Hi, to answer this question we have to apply an exponential growth function:  

A = P (1 + r) t  

Where:  

p = original population (in 2000)

r = growing rate (decimal form) = 4/100 = 0.04

t= years  

A = population after t years  

Replacing with the values given:  

A = 236,000 (1+ 0.04) ^t

To find the population in 2009:

We have to calculate the number of years passed since 2000: (2009-2000 = 9 years =t)

Substituting t=9 in the function:

A = 236,000 (1+ 0.04)^9

A =335,902 people

Feel free to ask for more if needed or if you did not understand something.
