What is the sum of 2/10 + 6/100

Answer: 13/50

Step-by-step explanation: To add these 2 fractions together, 2/10 + 6/100, we need a common denominator. The common denominator is simply the least common multiple for the 2 denominators which in this case is 100.

In order to get a denominator of 100 in the first fraction, we must multiply our denominator of 10 by 10.

The problem is we can't just multiply the denominator of a fraction bt 10 because that changes its value.

However if we also multiply the numerator of the fraction by 10, we're actually multiplying the fraction by 10/10 which is 1 and when we multiply anything by 1, it doesn't change its value. So our first fraction becomes 20/100. Notice that 20/100 has the same value as 2/10.

Since 6/100 already has a denominator of 100, we leave it.

So we have 20/100 + 6/100.

To add like fractions, we add across the numerators and keep the same denominator.

So 20/100 + 6/100 gives us 26/100.

Since the fraction 26/100 is not in lowest terms, we divide the numerator and denominator by 2 to get the equivalent fraction 13/50.

Answer:

26/100 which is simplified to 13/50

Step-by-step explanation:

you have to get equal denominators so multiply 2/10 by 10 on top and bottom to get 20/100 then you can add 6/100 plus 20/100 which is 26/100 . denominators stay the same 26/100 can be simplified to 13/50

A tiling company completes two jobs. The first job has $1200 in labor expenses for 40 hours worked, while the second job has $15
daser333 [38]

Answer:

The correct option is;

1560 = 30(52) + b

Step-by-step explanation:

The cost of the first job = $1,200 in labor and expenses

The number of hours worked in the first job = 40

The second job costs $1,560 in labor and expenses

The number of hours worked in the second job = 52

If the cost of labor per hour = L and the expenses = b, we have;

$1,200 = 40×L + b......................(1)

$1,560 = 52×L + b.......................(2)

Subtracting equation (1) from (2), we have;

52×L + b - (40×L + b) =  52×L - 40×L + b - b = $1,560 - $1,200 = $360

12×L = $360

L = $360/12 = $30/hour

From equation (1), we have;

$1,200 = 40×L + X =  40×$30 + b

Therefore, the equation that can be used to calculate the y-intercept of the linear equation is either;

1200 = 40(30) + X or 1560 = 32(52) + b, which gives the correct option as 1560 = 32(52) + b

The top of a ladder is 4m up a vertical wall.The bottom is 2m from the wall.The coordinate axes are the wall and the horizontal
mash [69]

Answer:

Part a) y=-2x+4

Part b) The coordinates of the point are (\frac{4}{3},\frac{4}{3})

Step-by-step explanation:

Part a) Find the equation representing the ladder

we have the ordered pairs

(0,4) and (2,0)

Find the slope

m=(0-4)/(2-0)=-2

Find the equation of the line in slope intercept form

y=mx+b

we have

m=-2\\b=4

substitute

y=-2x+4

Part b) A square box just fits under the ladder.Find the coordinates of the point where the box touches the ladder.

If the box is a square

the x-coordinate of the point where the box touches the ladder must be equal to the y-coordinate

x=y

y=-2x+4

substitute

x=-2x+4\\3x=4\\x=\frac{4}{3}

y=x=\frac{4}{3}

therefore

The coordinates of the point are (\frac{4}{3},\frac{4}{3})
