Answer:

X = 6.2

Step-by-step explanation:

\sin(48)  =  \frac{4.6}{x}  \\ 0.7 =  \frac{4.6}{ x }  \\ x = 4.6  \div 0.7 = 6.2

Girl 45 mins to Deliver papers on her route however if her brother have a good solid 20 minutes how long would it take if it was
LenKa [72]

Answer:

36 minutes

Step-by-step explanation:

It takes 45 mins to deliver paper on her route.

Let X be the amount of time it takes the brother to complete the route.

The brother works at the rate of 1/x route per min

The girl works at the at the rate of 1/45 route per min

Girl and brother working together works at rate of 1/20 route per min

1/x + 1/45 = 1/20

Multiply through by 180x

180 + 4x = 9x

4x - 9x = -180

-5x = -180

x = -180 / -5

x = 36 mins.

It takes the brother 36 minutes to complete route alone.

A manufacturing company produces engines for light aircraft . The graph shows the number of engine produced each year since the
photoshop1234 [79]

Answer:

y=13x+32

149 engines in 9th year

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

Please have a look at the attached photo.  

My answer:

From a look at the photo and the data plot can be represented by the function, so we can pick 2 points in our given graph

  • (x1, y1) = (2,60)
  • (x2, y2) = (5,99)

The standard form of a linear equation is:

y = mx + b where:

  • m is the slope
  • b is the y-intercept

We know the slope of the function can be found as following:

m = \frac{y2 - y1}{x2 - x1}  so in this situation we have:

<=> m=\frac{99-60}{5-2}=\frac{39}{3}=13

=> y = 13x + b (1)

Because the line goes through point  (2,60) so we substitute it into (1):

60 = 13*2 + b

<=> b = 60 - 26 = 34

=> y = 13x + 34

Now we will substitute x=9 to find the engines produced by company in 9th year as:

y=13(9)+32\\y=117+32=149

Hence, the company will produce 149 engines in 9th year
