Answer:

10 units

Step-by-step explanation:

We are given that

BD=x+29

AD=x+39

AC=20

BC=x+19

AC=AB+BC

20=AB+x+19

AB=20-x-19=1-x

AD=AB+BD

x+39=1-x+x+29

x=30-39=-9

Substitute the value of x=-9

Then , we get BC=-9+19=10 units

Answer: BC=10 units

If neither a nor b are equal to zero, which answer most accurately describes the product of (a + bi)(a - bi)?
Scrat [10]

Answer:  the correct option is

(D) The imaginary part is zero.

Step-by-step explanation:  Given that neither a nor b are  equal to zero.

We are to select the correct statement that accurately describes the following product :

P=(a+bi)(a-bi)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

We will be using the following formula :

(x+y)(x-y)=x^2-y^2.

From product (i), we get

P\\\\=(a+bi)(a-bi)\\\\=a^2-(bi)^2\\\\=a^2-b^2i^2\\\\=a^2-b^2\times (-1)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~[\textup{since }i^2=-1]\\\\=a^2+b^2.

So, there is no imaginary part in the given product.

Thus, the correct option is

(D) The imaginary part is zero.

Alenkinab [10]
The inequality should be
12 \leqslant 12x  < 180
The sign on the right is only a 'smaller than' sign because he spent less than 180.
On the left, assuming that even if Calvin took nobody (poor Calvin), we should assume that he at least went himself, hence he spent a minimum of $12.

Pls help me so I can pass
Sholpan [36]

Answer:

A

Step-by-step explanation:

V = (0.04)*H (Company P)

V = (0.06)*H (Company S)

V represents the vacation hours and H is the hours worked

If they both work 2080 hours

V1 = (0.04)*(2080) = 83.2 vacation hours (Company P)

V2 = (0.06)*(2080) = 124.8 vacation hours (Company S)

124.8 - 83.2 = 41.6 hrs
