Answer:

See Explanation

Step-by-step explanation:

According to the Question,

Steps of construction:

  • Step I - Draw a line segment AB = 7 cm with the help ruler.
  • Step II - with vertex A, by using compass take more than half of AB and draw arcs, one on each side of AB.
  • Step III - with vertex B, by using a compass with the same length, cut the previous arcs at X and Y respectively.
  • Step IV - with help of the ruler join the points X and Y Thus XY is the perpendicular bisector of line AB.

You design a new app for cell phones. Your revenue for x downloads is given by f(x) = 3x Your profit
Snowcat [4.5K]

Answer:

p = 2.7x - 20

p(90) = $223

Step-by-step explanation:

revenue → f(x) = 3x  ,where x is the number of downloads.

the statement “Your profit p is $20 less than 90% of the revenue for x downloads”

<u><em>means</em></u>

p=90\% f\left( x\right)  -20

<u><em>means</em></u>

<u><em></em></u>p=\frac{90}{100} \times f\left( x\right)  -20

<u><em>means</em></u>

p=\frac{9}{10} \times (3x)  -20

<u><em>means</em></u>

p=\frac{9}{10} \times (3x)  -20

<u><em>means</em></u>

p=2.7x -20

………………………………

the profit for 90 downloads :

= p(90)

= 2.7×(90) - 20

= $223

If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalen
ozzi

<u>Answer:</u>

<em>Equation is  4x-6(6x-1) = -11 </em>

<u>Step-by-step explanation:</u>

<em>The set of equations given are                           </em>

<em>6x-y=1 </em>

<em>4x-3y=-11 </em>

A pair of linear equations in <em>two variables x and y is given</em> in the set of equations. If there are two variables we require two equations to find the <em>value of variables</em>. Substitution is one among the methods used to solve pair of linear equations in two variables.

Here we have to <em>determine the value of y</em> from the first equation and then substitute it in the second equation.

<em>6x-y=1 </em>

<em>y=6x-1 </em>

<em>Substituting this value in second equation 4x-6y=-11 </em>

<em>we get </em>

<em>4x-6(6x-1) = -11 </em>

Answer:

  • 90

Step-by-step explanation:

<u>Factorize both numbers:</u>

  • 900 = 2*2*3*3*5*5
  • 270 = 2*3*3*3*5

<u>Common factors are:</u>

  • 2*3*3*5

<u>So HCF is:</u>

  • HCF(900, 270) = 2*3*3*5 = 90
