Find the lowest common multiple (LCM) of 28 and 35.​

Mathematics

Ahat [919]3 years ago

Step-by-step explanation: I would first create a factor tree for these numbers and break them down into their prime factorization.

First, 28 is 7 x 4 and 4 is 2 x 2

Next, 35 is 7 x 5

In our factors tree, a 7 is a factor that is shared so we pull out a 7.

Now, we multiply all of our factors that don't pair up

and in this case, that's a 2, another 2, and a 5.

So our LCM is 7 x 2 x 2 x 5 or 140.

140

the lcm of two non-zero integers ×(28) and y(35) ,is the smallest posetive integer m(140) that is divisibleby both ×(28)and y(35) Without any remainder

Answer:

19.82%

Step-by-step explanation:

Add all members that want weight lifting

47 + 21 + 14 + 29 = 111

111 / total members

111 / 560 = 0.1982

0.1982 * 100% = 19.82%

A water truck is filling a swimming pool. The equation that represents this relation is y=18.25x where y is the number of gallon
QveST [7]

Answer:

See explanation

Step-by-step explanation:

The question is incomplete, however, one of the requirements of this question while I searched, was to make a table and sketch the equation.

If this is the case, then, all you need to do is take the equation, Assume some values for x, and compute the values of y. Then, you can do the graph.

I begin with value from 0 to 10.

This is the example of calculations:

x = 0

y = 18.25*0 = 0

for x = 0, we get y = 0. For x = 2:

y = 18.25 * 2 = 36.5

If we keep doing this, we should get a straight line. See the graph and attached table. If the question is asking another thing, then please get back to me to answer it.

Use Pascal's triangle to expand the binomial.
KatRina [158]

Answer:

(d - 5)^6 = d^6 - 30*d^5 + 375*d^4 - 2500*d^3 + 9375*d^2 - 18750*d + 15625

Step-by-step explanation:

Suppose you have (x + y)^6, the numbers  in the 6th row of Pascal's triangle are the coefficients of the terms in a sixth order polynomial.

In the figure attached, Pascal's triangle is shown.

The coefficients are 1, 6, 15, 20, 15, 6,1. Then:

(x + y)^6 =  x^6 + 6*x^5*y + 15*x^4*y^2 + 20*x^3*y^3 + 15*x^2*y^4 + 6*x*y^5+ y^6

Replacing x = d and y = -5:

(d - 5)^6 =  d^6 + 6*d^5*(-5) + 15*d^4*(-5)^2 + 20*d^3*(-5)^3 + 15*d^2*(-5)^4 + 6*d*(-5)^5+ (-5)^6

(d - 5)^6 = d^6 - 30*d^5 + 375*d^4 - 2500*d^3 + 9375*d^2 - 18750*d + 15625
