A collection of coins contains a total of sixteen dimes and quarters. It is worth $2.20 in all. How many dimes are in the collection?

Answers

Answer 1

9514 1404 393

Answer:

  12 dimes

Step-by-step explanation:

Let q represent the number of quarters. Then the number of dimes is 16-q and the total value is ...

  0.25q +0.10(16 -q) = 2.20

  0.15q +1.60 = 2.20 . . . . . . . simplify

  0.15q = 0.60 . . . . . . . . subtract 1.60

  q = 4 . . . . . . . . . . . divide by 0.15

  16-q = 12

There are 12 dimes in the collection.

Answer:

y=-2x+1

Step-by-step explanation:

First, you calculate the slope, which is rise over run: -9+5 / 5-3 = -2.  Then, find b by substituting the coordinates (of either one point) into the slope-intercept formula, y = mx + b.  

Answer:

Step-by-step explanation:

The slope intercept form of a line is

y=mx+b, where m=slope and b= y intercept

The slope of a line is defined as

m=(y2-y1)/(x2-x1), in this case we have points (3,-5) and (5,-9)

m=(-9-(-5))/(5-3)

m=-4/2

m=-2, so our line is now

y=-2x+b, using point (3,-5) we can now solve for b

-5=-2(3)+b

-5=-6+b

1=b so the completed line is

y=-2x+1

The product of two numbers is negative. What conclusion can you draw about the sign of the quotient of the same numbers? *​

Answers

According to the law of signs for division, the quotient of 2 numbers of different sign is negative

Answer:

The quotient is negative.

Step-by-step explanation:

The rules of signs for multiplication and division of two numbers are the same.

If you multiply or divide two numbers with the same sign (both positive or both negative), the answer is positive.

If you multiply or divide two numbers with different signs (one positive and one negative), then the answer is negative.

Since the product is negative, then the quotient is also negative.

Answer: The quotient is negative.

The question want you to find the graph that has a constant rate of change and has a y intercept of (0,0) so essentially

The question is asking "which graph best represents a proportional relationship."

Looking at C we notice that the line is straight ( meaning it has a constant rate of change) and it also goes through the origin therefore C is your answer

A right cylindrical container can hold 96π cubic meters of liquid when full. The height of the container is 6 meters what is the radius, r, of the container?

A. 4 m
B. 5 m
C. 2 m
D. 6 m

Answers

Answer:

A. 4 m

Step-by-step explanation:

The formula for the volume of a cylinder is πr^2 x h

r = radius    h = height

So, with this you can reverse it to find the radius since you know the height.

96π/6 = 16π

√16π = 4π

Step-by-step explanation:

The first term is 5 and the common difference is 9-5=4, so the n-th term is ...

  an = a1 +d(n -1)

  an = 5 +4(n -1) = 4n +1

Then the term number for the term 129 is ...

  129 = 4n +1 . . . . . put the given value in the formula

  128 = 4n  . . . . . . . subtract 1

  32 = n . . . . . . . . . .divide by 4

The 32nd term is 129.

(60-5.8) ÷ 5 - 3^2
explain in an essay how to do this TY!!

Answers

Answer:

(60-5.8) ÷ 5 - 3² = 1.84 (approx)

Step-by-step explanation:

(60-5.8) ÷ 5 - 3²

First simplify the numbers inside the bracket.

(60-5.8) = 54.2

Now, the equation is in the form of,

54.2 ÷ 5 - 9

Put 54.2 ÷ 5 in a bracket for easy calculation.

(54.2 ÷ 5) - 9

Now simplify the numbers inside the bracket again, 54.2 ÷ 5 = 10.84

Subtract 9 from 10.84

10.84 - 9

You will now get the answer as,

1.84 (approx)
