Answer:

The area of the entire rectangle, in standard form, is

x² + 9x + 8

Step-by-step explanation:

Area of the entire rectangle:

area = width * length

area = (x+1)(x+8)

= x*x + x*8 + 1*x + 1*8

= x² + 8x + 1x + 8

= x² + 9x+ 8

6 sec can take penny to strike the ground.

Solution:

Given data:

$H_0=288$ feet

$V_0=48$ feet

$h(t)=288+48t-16t^2$

Re-arrange the terms from greatest degree to smallest degree.

$h(t)=-16t^2+48t+288$

We can solve it by applying quadratic formula,

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

Here a = –16, b = 48, c = 288

$$t=\frac{-48\pm \sqrt{48^2-4(-16)(288)}}{2(-16)}$

$$t=\frac{-48\pm \sqrt{2304+18432}}{-32}$

$$t=\frac{-48\pm \sqrt{20736}}{-32}$

$$t=\frac{-48\pm144}{-32}$

Now, write find two t's using plus and minus operation.

$$t=\frac{-48+144}{-32},\ \ t=\frac{-48-144}{-32}$

$$t=\frac{96}{-32},\ \ t=\frac{-192}{-32}$

t = –3 (or) t = 6

We cannot write time is negative. so neglect t = –3.

Therefore t = 6.

Hence 6 sec can take penny to strike the ground.

Richard Lens receives a 3.5% commission for selling cleaning supplies. What is his commission on sales of $122,591?

LekaFEV [45]

Answer:

$4,290.69

------------------------------------------------------------------------------------------------------

- To find the commission, just convert the percentage into a decimal (divide by 100) and multiply it by the sales.

3.5% = 0.035

122,591 x 0.035 = <em>$4,290.69</em>

We are given the following conversion factor:

$10\text{ miles=}16\text{ km}$

We are asked to determine how many miles are 140 km. To do that we use the quotient of the conversion factor where the unit we want to convert to is in the numerator and the given unit in the denominator. Since we want to find miles we use the following quotient:

$\frac{10\text{ miles}}{16\text{ km}}\times140\operatorname{km}$

Solving the operations we get:

$\frac{10\text{ miles}}{16\text{ km}}\times140\text{ km=87.5 miles}$

Ms. Snyder is giving a 28-question test that is made up of multiple choice questions worth 2 points each and open response quest

zlopas [31]

Answer:

x *2 + (28-x)*4 = 100

Step-by-step explanation:

Given

Total number of questions in the paper = 28

Out of these 28 questions let us say that x number of questions are of 2 points and 28-x questions are of 4 points.

Also, the complete test is of 100 marks

Thus, the linear equation representing the

x *2 + (28-x)*4 = 100
