You can set up a ratio as follows:
$\frac{x-22}{87.5}= \frac{22}{77}$

Solve for x by cross-multiplying:
$(x-22)(77) = (87.5)(22)$
$x = \frac{(87.5)(22)}{77} + 22= 47.01$

Since we need the answer in mm and right now we have it in feet, we need a conversion ratio. After googling it, the conversion ratio is: 1ft = 304.8mm
$47.01(304.8) = 14326.64$

So, the answer is 14326.64 mm.

What is the graph of the function rule?<br><br> y = 3x - 2<br><br> Choose from the pictures

bulgar [2K]

we have

$y=3x-2$

we know that

this is the equation of a line, to identify which is the graph we will proceed to determine the points of intersection with the coordinate axes

1) <u>Find the y-intercept</u>

the y-intercept is when the value of x is equal to zero

For $x=0$

find the value of y

$y=3*0-2$

$y=-2$

2) <u>Find the x-intercept </u>

the x-intercept is when the value of y is equal to zero

For $y=0$

find the value of x

$0=3x-2$

$x=(2/3)$

therefore

the answer is the option B ( see the attached figure)

Projectile Is shot upward from the surface of Earth with an initial velocity of 136 meters per second. Use the position

Anna007 [38]

Answer:

$v(3\,s) = 106.6\,\frac{ft}{s}$ , $v(15\,s) = -11\,\frac{ft}{s}$

Step-by-step explanation:

The velocity function of the projectile is obtained by deriving the position function:

$v(t) = -9.8\cdot t + 136$

Now, the velocities after 3 and 15 seconds are, respectively:

$v(3\,s) = -9.8\cdot (3) + 136$

$v(3\,s) = 106.6\,\frac{ft}{s}$

$v(15\,s) = -9.8\cdot (15) + 136$

$v(15\,s) = -11\,\frac{ft}{s}$

Step-by-step explanation:

52.10 - 49.62 = 2.48

2.48/49.62 x 100 = 4.998%

The percentage increase in the price is approximately 5%. Hope this helps! :)

What is the area of this quadrilateral

sammy [17]

Answer:

C

Step-by-step explanation:

First, let's work out the two triangles:

Area of triangle: bxh/2

2 x 8/2 = 8

Because there is two triangles multiply 8 by 2 = 16

To work out the area of the central rectangle:

Area of rectangle: l x w

3 x 8 = 24

Add 16+24 = 40 square feet
