Answer:

1.42%

Step-by-step explanation:

let y be the unknown number

49% × y = 49y%

49y% = 56

then the co-efficient of 'y' that is 49% will cancel out leaving 'y' and resulting in 56÷49 resulting in 1.42

therefore the original number is 1.42

Say that the economy is in an expansion, causing wages to increase by six percent. if you previously received a monthly salary o
Westkost [7]

From previously received a monthly salary of $1,375.00, Your new monthly salary increase by six percent would be $1,457.50.

What is the percentage?

A percentage is a minimum number or ratio that is measured by a fraction of 100.

You previously received a monthly salary of $1,375.00

Now by economic expansion, causing wages to increase by 6%

Increment of the salary = 6% of 1,375.00

= 6/100 × 1,375

= 0.06 × 1,375

= $82.50

So, your new monthly salary would be = $1,375.00 + $82.50

                                                               = $1,457.50

Hence, your new monthly salary would be $1,457.50.

A machine shop produces heavy duty high endurance 20-inch rods that are meant for use in a variety of military grade equipment.
QveST [7]

Answer:

The probability that a defective rod can be salvaged = 0.50

Step-by-step explanation:

Given that:

A machine shop produces heavy duty high endurance 20-inch rods

On occasion, the machine malfunctions and produces a groove or a chisel cut mark somewhere on the rod.

If such defective rods can be cut so that there is at least 15 consecutive inches without a groove.

Then; The defective rod can be salvaged if the groove lies on the rod between 0 and 5 inches i.e ( 20  - 15 )inches

Now:

P(X ≤ 5) = \dfrac{5}{20}

= 0.25

P(X ≥ 15) = \dfrac{5}{20}

= 0.25

The probability that a defective rod can be salvaged = P(X ≤ 5) + P(X ≥ 15)

= 0.25+0.25

 = 0.50

∴ The probability that a defective rod can be salvaged = 0.50

Which phrase best descubes the translation from the graph y = (x - 5)2 + 7 to the graph of y = (x + 1)2 - 2?
Ber [7]

Answer:

"6 units left and 9 units down"

Step-by-step explanation:

Suppose a function is given in this form:

y=(x-a)^2+b

This is the parent function y = x^2

  • translated a units right (left if there was a + before a)
  • translated b units up (down if there was a - before b)

Now, to go from  y=(x-5)^2+7  to  y= (x+1)^2-2 , we can see that:

  • first function is 5 units right and 2nd one is 1 unit left, so there is a horizontal translation of 6 units left
  • first function is 7 units above and 2nd one is 2 units down, so there is a vertical translation of 9 units down

Thus, "6 units left and 9 units down" is the transformation(translation).
