If one pound of cement cost r dollars, what is the price of z pounds in cents
slavikrds [6]

Answer:

100rz cents.

Step-by-step explanation:

The price of cement with respect to its weight is proportional.

So, we can write p ∝ w  

where p is the price in dollars and w is the weight of the cement in pounds.

⇒ p = kw  ............... (1) {Where, k = proportionality constant}

Given that, one pound of cement cost r dollars.

So, from equation (1), we can write

r = k(1)

⇒ k = r

So, the equation becomes p = rw .............. (2)

Now, for w = z pounds, the price will be p = rz dollars. {From equation (2)}

Therefore, the price of z pounds in cents will be 100rz cents. (Answer)

A coed little league team had 18 players . Even though it was raining half the girls and one third of the boys showed up for the
Genrish500 [490]

Answer:

The number of Girls players in the Team of 18 players is 6 .

Step-by-step explanation:

Given as :

The total number of player including boys and girls = 18

And \frac{1}{2} times girls player +  \frac{1}{3} times boys player = 7

Let The number of boys player = B

The number of girls player = G

So, According to question

G + B = 18      ...1

\frac{1}{2} × G +  \frac{1}{3} × B= 7

or, \frac{G}{2}  +  \frac{B}{3} = 7    ...2

or, Put the value of B from  eq 1

or,  \frac{G}{2}  +  \frac{18 - G}{3} = 7  

Or,  \frac{G}{2}  -  \frac{G}{3}  + 6 = 7

or,  \frac{3G - 2G}{6}  = 7 - 6

Or,  \frac{G}{6}   = 1

∴ G = 1 × 6 = 6

Hence The number of Girls players in the Team of 18 players is 6 . Answer

write an expression to describe a rule for the sequence. Then find the 100th term in the sequence 3, 10, 17, 24, 31, 38, ...
blagie [28]
As we can tell, the first number is 3, so we'll have a y-intercept in our equation and overall. Secondly, we can tell it's increasing by 7 each time, so we can tell that's the rate. But, it won't just be 3+7x, if we plug 1 in, it would be 10 and not 3. We need to put in the parenthesis 3+7(x-1). If we put one in, we would receive three. Let's make sure this works.
3+7(5-1)
3+7(4)
3+28
31
31 is the fifth terms.
So the expression would be 3+7(x-1).
Let's find the 100th term.
3+7(100-1)
3+7(99)
3+693
696
So the 100th term would be 696.
