Mathematics

Since the figure has both sides congruent and 90 degree angle, the figure is a square. That means that the angle of the diagonals are 90 degrees so m∠1=90. This means 90=3y+6 so y is 28

A tool box contains 12 bolts and 10 nuts. If a handyman grabs 8 items randomly, what is the probability that he gets four bolts
belka [17]

Answer:

(c) 0.325

Step-by-step explanation:

Given,

The number of bolts = 12,

Numbers of nuts = 10,

Total items = 12 + 10 = 22

Thus, the number of ways of choosing 8 items out of 22 items = C(22,8)

Now, the number of ways of choosing 4 bolts and 4 nuts = C(12, 4) × C(10, 4)

Hence, the probability of getting four bolts and four nuts

=\frac{\text{ways of choosing 4 nuts and 4 bolts}}{\text{Total ways of choosing 8 items}}

=\frac{C(12,4)\times C(10,4)}{C(22, 8)}

=\frac{\frac{12!}{4!8!}\times \frac{10!}{4!6!}}{\frac{22!}{8!14!}}

=\frac{495\times 210}{319770}

=0.325077399381

\approx 0.325

Therefore, option (c) is correct.

Please help, system of equasions
arlik [135]

Answer:

x = 4, y = 4

Step-by-step explanation:

x+y=8

The total number of caps or shirts needed will be equal to the total amount of people in the system.

6x+3y=36

We can multiply the amount of caps and shirts by their price to get the total price needed.

y=8-x\\6x+3(8-x)=36\\6x+24-3x=36\\3x=12\\x=4

We can substitute one equation into another to solve for x.

Now we put our x value back into the other equation to get y

4+y=8\\y=4

Now we substitute both of our values into our second equation to verify that they are correct

6(4)+3(4)=36

So correct!
