Answer:

0.3

Step-by-step explanation:

1.) Remember PEMDAS. You have to solve for exponents before you multiply. So, 10 to the power of -1 is 0.1

2. Then you have to multiply 3x0.1 and you get your answer, 0.3

Hope that this helps :)

How do you solve this absolute value equatuon? 4|x - 1| - 7 = -3
MatroZZZ [7]
4|x - 1| - 7 = -3    |add 7 to both sides

4|x - 1| = 4    |divide both sides by 4

|x - 1| = 1 ⇔ x - 1 = 1 or x - 1 = -1    |add 1 to both sides

x = 2 or x = 0

Answer: B.

Find a,b,c and d?..........
cupoosta [38]

9514 1404 393

Answer:

  a = 6, b = 12, c = 6, d = 6√3

Step-by-step explanation:

The two triangles are the "special" triangles.

The 45-45-90 triangle has side lengths in the ratios 1 : 1 : √2.

The 30-60-90 triangle has side lengths in the ratios 1 : √3 : 2.

Then ...

  c : a : 6√2 = 1 : 1 : √2   ⇒   c = a = 6

and ...

  a : d : b = 1 : √3 : 2   ⇒   d = 6√3 and b = 12 . . . (since a=6)

The lengths are ...

  a = 6, b = 12, c = 6, d = 6√3

rjkz [21]

a) n (No. of peoples) = 50

r (No. of prizes) = 3

p(n,r) = p (50,3)

\begin{gathered} P(n,r)=\frac{n!}{(n-r)!} \\ P(50,3)=\frac{50!}{(50-3)!} \\ =117600 \end{gathered}

b) n(No. of players)=14

r (No. of players for Batting)=9

\begin{gathered} P(14,9)=\frac{14!}{(14-9)!} \\ =726485760 \end{gathered}

c)n(Total applicants)=30

r(tester positions)=4

\begin{gathered} P(30,4)=\frac{30!}{(30-4)!} \\ \text{              =}\frac{30!}{26!} \\ \text{              =657720} \end{gathered}
