Answer:

first box (x) = 4

second box (y) = 3

3rd box (z) = 8

Step-by-step explanation:

<h2>we can equate both side of equality and can solve separately.</h2>

\frac{1}{2}  -  \frac{1}{8}  =  \frac{x}{8}  -  \frac{1}{8}

taking \:  \: lcm \:  \: on \:  \: both \:  \: side \\  \\ \frac{4 - 1}{8}  =  \frac{x - 1}{8}

<h3>multiplying both side by 8 </h3>

we get ,

<h3>4 - 1 = x - 1 \\  \\ 3 = x - 1 \\  \\ adding \: 1 \:  \: on \:  \: both \:  \: side</h3>

3+1 = x-1+1

4 = x

\frac{1}{2}  -  \frac{1}{8}  =  \frac{y}{z}

\frac{4 - 1}{8}  =  \frac{y}{z}

\frac{3}{8}  =  \frac{y}{z}

Please solve i will give brainiest 100 point question ****** do the whole page please need to pass or i will fail its my final t

Answer:

1. Find the difference between the areas.

<u>Area of the small rectangle</u>: (x+2)(x+7)=x^2+7x+2x+14=x^2+9x+14

<u>Area of the big rectangle</u>: (x+9)(x+11)=x^2+11x+9x+99=x^2+20x+99

The difference is: 11x+85

( x^2+20x+99)- (x^2+9x+14)=x^2+20x+99-x^2-9x-14=11x+85

2.

You can solve this question just by looking at the graph.

a) The height is 4 meters.

f(d)=h=-2d^2+7d+4

To find the height of the bleachers, we should consider the moment before the shoot, when the distance is equal to 0.

f(0)=h=-2(0)^2+7(0)+4

h=4

The height is 4 meters.

b) 9 meters.

For d=1

f(1)=h=-2(1)^2+7(1)+4

f(1)=h=-2+7+4

h=9

b) The ball travels 4 meters.

But to calculate it, it is when h=0

0=-2d^2+7d+4

Using the quadratic formula:

$d=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

$d=\frac{-7 \pm \sqrt{7^2-4\left(-2\right)4}}{2\left(-2\right)}$

$d=\frac{-7\pm\sqrt{81}}{-4}$

$d=\frac{-7\pm9}{-4}$

It will give us to solutions, once it is a quadratic equation, but we are talking about a positive distance.

$d=-\frac{1}{2} \text{ or }d=4$

3.

In this question, we have to find the area of the cylinder and the sphere.

From the information given, we have

a = 5mm and d = 5mm, therefore the radius is 2.5 mm.

The volume of a cylinder:

V=\pi r^2h

V=\pi (2.5)^2 \cdot 5

V=31.25 \pi

V_{c} \approx 98.17 \text{ m}^3

The volume of the sphere:

$V=\frac{4}{3}  \pi r^2$

V_{s} \approx 65.4 \text{ m}^3

The volume of the capsule is approximately 163.57  \text{ m}^3
