8 0

Answer:

1680

Step-by-step explanation:

First do the prime factorization:

16=2x2x2x2

28=2x2x7

42=2x3x7

60=2x2x3x5

To find least common multiple (LCM), write down all prime factors of one of the number and multiply by factors from other numbers that was not in that number:

LCM=2x2x3x5x7x2x2=1680

The list of two-digit numbers whose digits add up to 10 would be:
19
28
37
46
55
64
73
82
91

Now the numbers have the same digits only reversed and the difference between the two numbers is 18 - the only pair that fits this description is 46 and 64, thus those are the two numbers

Point P is located at (−2, 7), and point R is located at (1, 0). Find the y value for the point Q that is located two over three
otez555 [7]

Answer:

y_Q=\dfrac{21}{5}=4.2

Step-by-step explanation:

If the point Q that is located two over three the distance from point P to point R, then PQ:QR=2:3.

Use formula to find the coordinates of the point Q:

x_Q=\dfrac{3x_P+2x_R}{3+2}\\ \\y_Q=\dfrac{3y_P+2y_R}{3+2}

In your case, P(-2,7) and R(1,0), then

x_Q=\dfrac{3\cdot (-2)+2\cdot 1}{3+2}=\dfrac{-4}{5}\\ \\y_Q=\dfrac{3\cdot 7+2\cdot 0}{3+2}=\dfrac{21}{5}

Evaluate C(7, 4) 35 210 5,040
sashaice [31]

Answer:

\boxed{\boxed{C(7,4)=35}}

Step-by-step explanation:

Here, we have to calculate

C(7,4)=\dbinom{7}{4}

From combination we know that,

\dbinom{n}{r}=\dfrac{n!}{r!(n-r)!}

Here,

n = 7 and r = 4, so putting these,

\dbinom{7}{4}=\dfrac{7!}{4!(7-4)!}

=\dfrac{7!}{4!\ 3!}

=\dfrac{5040}{24\times 6}

=\dfrac{5040}{144}

=35
