Answer:

72 mph

Step-by-step explanation:

<em>Please give brainliest</em>

You have distance =210 miles

Increase it by 20%

210+(210*0.2) = 252 miles I wrote 0.2 instead of writing 20%/100% hope you understand.

The new route is 252 miles

Time travelled = 3.5 hours

Speed=distance/time

Speed = 252/3.5 = 72 mph

A 5 divided by 48 lottery involves choosing 5 of the numbers from 1 through 48 and a 4 divided by 35 lottery involves choosing 4
Anika [276]

Answer:

4/35 lottery is easier to win.

Step-by-step explanation:

For the 5/48 lottery, the winning probability is \frac{5}{48} ≈0.1042

For the 4/35 lottery, the winning probability is \frac{4}{35} ≈ 0.1143

Since \frac{4}{35}  >  \frac{5}{48} , the lottery where one chooses 4 of the numbers 1 through 35 is easier to win.

Can someone please help me with this.
allsm [11]

Answer:

10

Step-by-step explanation:

Given expression is |8-6 i|.

|8-6 i| is a complex expression.

The value of<em> i </em>is –1.

By definition of absolute value, |a+b i|=\sqrt{a^{2}+b^{2}}

Now, substitute |8-6 i| in the above formula.  

\Rightarrow|8-6 i|=\sqrt{8^{2}+(-6)^{2}}  (since <em>i </em>= –1)

                  =\sqrt{64+36}  (since 8^{2}=64 and                    –6^{2}=36)

                  =\sqrt{100}  (Square root of 100 is 10)

                  = 10

Hence, the value of the expression  |8-6 i| is 10.
