2 answers:

5 0

The question that is asked is pretty straight forward. Only thing that needs to be found is the number of 30 in the number 600. By dividing 600 by 30 we can arrive at the desired result.
Number of 30 in 600 = 600/30
   = 60/3
   = 20
So there are 20 number of 30s in the number 600. This method can be used to find answers to several other similar kind of questions like the number of 10s in 1000.Following the same procedure we get
Number of 10 in 1000 = 1000/10
   = 100

If you think of the factors that make 600 you get 20 factors of 30 so your answer would be 20

Identify the equation that represents a proportional relationship.

Ket [755]

Answer:

c. $y=2x$

Step-by-step explanation:

I'd generally say this would depend on what your definition of proportional is, but there's still one clear answer in this case regardless.

Here, a direct proportional relationship will pass through (0, 0), meaning it will not have a y-intercept and y will be 0 when x is 0.

$y=mx+b$

Because b is the y-intercept, C is the answer as it is the only answer that does not have one.

There are 31 coins of dimes and quarters. If the number of dimes is 5 more than the number of quarters, how many quarters are th

emmasim [6.3K]

Answer:

13 Quarters and 18 Dimes

Step-by-step explanation:

Let D and Q stand for the numbers of Dimes(D) and Quarters(Q). Give x and y a break, and make it easier to remember which is which.

D + Q = 31

D = Q + 5

Therefore:

D + Q = 31

(Q+5) + Q = 31

2Q + 5 = 31

2Q = 26

Q = 13

Then D = (13+5) or 18

================

Check:

D + Q = 31 ?

18 + 13 = 31 YES

----------------------

D = Q + 5 ?

18 = 13 + 5 YES

F(x)=(x^3+4x^2+7x-9) d(x)=(x+3) divide using long division

Alchen [17]

The result is x^2 +x +4 -21/(x+3).

_____

Polynomial long division tends to be easier than numerical long division because the quotient term never needs adjustment. It is always the ratio of the highest degree terms of the dividend and divisor.

See the attachment for the intermediate steps.

30. Justify Reasoning The quotient of two negative integers results in an integer. How does the value of the quotient compare to

Ratling [72]

The quotient of 2 negative integers results in an integer.
-4/-2 = 2
the value of the quotient is positive whereas, the value of the original 2 integers are both negative. The reason being, is that when u divide two negatives, u get a positive.
