Answer:

First question :

The number of boys in a school is 6 more than 1/2 times of number of girls, if the number of boys is 81 then how many girls are there ?

Solution : Let x be the number of girls,

As per the above statement,

\frac{1}{2}x+6=81

Second question :

Two pipes filled two tanks of same size, if the difference in time taken by both pipes is 26 minute, if one takes 5 more than 2 times of the time taken by other, what is the time taken by smaller pipe,

Solution : If t be the time taken ( in minutes ) by smaller pipe,

So, the time taken by larger pipe = 2t + 5

As per the above statement,

(2t+5)-t=26

Third question :

The length of a pole is 4 times of the other pole if the sum of 2 times of small pole and 3 times of larger pole is equal to 990.50 inches what is the length of smaller pole,

Solution : If L be the length of smaller pole,

So, the length of larger pole = 4L,

As per the above statement,

2(L) + 3(4L) = 990.50

Which explanation provides the best real-world scenario of the graph?
Naddika [18.5K]
The last one is the only one that makes sense according to the standard position function.  -16t^2 is the pull of gravity on an object in free fall, and the height is 120 feet above the ground.  Hopefully that's what you need since there's no graph we can refer to

vector u is represented by the directed line segment RS and vector v is represented by the directed line segment OP. if R=(8,-2)
melamori03 [73]

The given points are

R=(8,-2) , S=(11,-6), O=(-3,-9), and P=(0,-13)

To find the value of u and v, we have to perform subtraction of the points . That is

u= RS = =

v = OP =  =

Since we get the same values of u and v , therefore the two vectors are equal .

Norma Jean makes $25 per hour. She works 35 hours per week. She gets a commission of 15% on her total sales. How much should Nor
TEA [102]

Answer:

$24166.67

Step-by-step explanation:

$25 per hour and works 35 hours per week

Norma Jean makes 35 * 25  (<em>without sales) = </em>$875

<em> </em>Total commission made by Norma<em> </em>= 4500-875 = $3625

<em>let total number of sales by Norma be x</em>

15% is the same as 15/100

<em>so </em>(15/100) * x =3625 <em> multiplying both sides by 100</em>

15x = 362500<em> making x subject of formula</em>

x = 362500/15

x = 24 166.67

Norma should sell total items worth $24166.67
