Help someone plz I'll give brainlest

-Dominant- [34]

Answer:

like with the whole page?? cause if so i got this KINDA

Step-by-step explanation:

the first one (2/9+2/9) = 4/9

the second one (1/4+2/4)=3/4

the third one (3/8+5/8)=1 whole or 8/8

i cant see the last one so ill skip to the bottom row

the first one (2/5-1/5)=1/5

(9/12-4/12)=5/12

(4/10-2/10)= 2/10

and ill give someone else a shot with the rest of the questions but yw

this is pretty simple but hit me up if you ever need more help

uysha [10]

Well, the number should be 2,222 since she wants the hundreds place to be a 2, being worth 200. Since she wanted all the digits to have the same number, it would be 2,222 for your final answer.

Hope this helped!

A flagpole is secured on opposite sides by two guy wires, each of which is 5 ft longer than the pole. the distance between the p

RideAnS [48]

The height of the flagpole to the nearest inch is 388 inches.

Explanation

According to the below diagram, AB is the flagpole which is secured on opposite sides by two guy wires, AB and AC.

Suppose, the length of the flagpole(AB) is $x$ ft.

As each of the guy wires is 5 ft longer than the pole, that means $AC= AD= (x+5)ft$

Also given that, the distance between the points where the wires are fixed to the ground is equal to the length of one guy wire. That means, $CD= (x+5)ft$

As $\triangle ABC$ and $\triangle ABD$ are congruent to each other, so $BC=BD= \frac{1}{2}CD= \frac{1}{2}(x+5) ft$

Now in right triangle $ABD$ , using Pythagorean theorem......

$AB^2+BD^2= AD^2\\ \\ x^2+[\frac{1}{2}(x+5)]^2= (x+5)^2\\ \\ x^2+ \frac{1}{4}(x+5)^2 = (x+5)^2\\ \\ 4x^2+(x+5)^2= 4(x+5)^2\\ \\ 4x^2= 3(x+5)^2\\ \\ 4x^2=3(x^2+10x+25)\\ \\ 4x^2-3x^2-30x-75=0\\ \\ x^2-30x-75=0$

Using quadratic formula, we will get.......

$x=\frac{-(-30)\pm \sqrt{(-30)^2-4(1)(-75)}}{2(1)}\\ \\ x= \frac{30\pm \sqrt{1200}}{2}\\ \\ x= 32.3205..., x=-2.3205...$

(Negative value is ignored as the height of the pole can't be in negative)

So, the height of the flagpole will be: $32.3205... ft =(32.3205...\times 12)inches = 387.846... \approx 388 inches$

Terry runs a snowplowing business. Income from snowplowing is given by the function f(x) = 35.5x + 6, where f(x) is the income i

eduard

It's C they are just out of order for the years.

f(x)=35.5x+6
For each year your plug in the snow total for x and solve
2006 x=53 so 35.5(53)+6=1887.5
2007 x=42 so 35.5(42)+6=1497
2008 x=55 so 35.5(55)+6=1958.5
2009 x=63 so 35.5(63)+6=2242.5
2010 x=58 so 35.5(58)+6=2065
2011 x=47 so 35.5(47)+6=1674.5

Hope that helps.
