We know that the sum of measure of any two sides of a triangle is greater than the third Angle.

So, in this case,

  • ( a + b ) > c

  • Or, 9 + 10 > c

  • Or, 19 > c

Now, here only 19 is only greater than 18.3 from the options. Hence, 18.3 is the correct answer.

Answer:

A) 18.3

Step-by-step explanation:

Since adding b and a gives 19.

c must be less than 19.

So, A) 18.3 is the correct answer

Paul went on a bike ride of 30 miles. He realized that if he had gone 8 mph faster, he would have arrived 12 hours sooner. How f
lara [203]

Answer: He actually rode 2 miles per hour on his trip

Step-by-step explanation: Maybe unconventional, but express the time it took, then figure the speed.

Time  = distance /speed  t will represent time, s is the speed:  t = 30/s Use the rime it would have taken at the higher speed to create an equation:

t-12 = 30/s+8   replace the y with the 30/s

30/s -12 = 30/s+8

(s)(30/s -12 ) = (s)(30/s+8 )  Cross multiply to cancel denominators  

(s-8)(30 -12s) = (s-8)(30s/s+8 ) ==> 30s +240 -12s² -96s =30s   Simplify:  

(-1)(-12s² -96s +240 ) =0 ==>  12s² +96s -240  divide all by 12

s² + 8s -20 = 0   Factor and solve for s

(s +10)(s -2) =0    s-2=0   S= 2  

Proof:

30/2 = 15 hours for original trip at 2mph,  

increase speed by 8mph   2 + 8 = 10mph

30 miles at 10mph takes 3 hours; that is 12 hours less than his actual trip.

Fir what values of p will the equation x^2=p have 1 real number solution why
Naddika [18.5K]

The only value of p for which the equation has exactly 1 real number solution is p=0.


If p<0, there are no real number solutions and if p>0, there are 2 real number solutions.


Hope this helps,

What is the slope of a line parallel to the line whose equation is 2x + 4y = 56.<br><br> HELP ASAP
Anton [14]

Answer:

Let's put this equation in standard form...

2x+4y=56\\4y=56-2x\\y=14-0.5x

If it is parallel, it would have the SAME slope but ANY OTHER y-intercept!!

For example...

y=-0.5x+304\\y=-0.5x-67

Hope this helps!!

What role do individuals play in a capitalist system?
Vitek1552 [10]
The very rich control the market and decide what industries to invest in or lend money too. They influence the government so that they don't have to pay very much in taxes, which would support the nation's infrastructure, & provide jobs. The middle class works hard to produce products, and also spends money on products, which helps to make the rich investors even more wealthy. The poor are typically unable to compete in a capitalist economy (for a number of reasons), & require public assistance to survive.
