Nomonde earns a total salary of R63 420 p.a . Deductions from her salary amount to R5 785 for the year . Her other expenses are

R130 rent per week , R3 890 transport for the year , R1 200 food, groceries and entertainment per month , R400 phone and internet per month , R7 220 clothes, books , stationery for the year .
Is the amount she earns enough to cover her annual expenses? to answer this question, first sort out the weekly , monthly, and annual expenses listed above. Multiply each weekly expense by 52, and each monthly expense by 12 . Then add their subtotals to the other annual expenses to get her total expense for the year . Then subtract this total from Nomonde's total annual salary

Answer: R63 420 p.a. earning is enough to cover her annual expenses and get R20 565 extras

Step-by-step explanation:

Let's do a simple calculation,

Her total earning = R63 420 per year

Deduction from salary = R 5 785 per year

Now

1 year has 52 weeks and 12 months approximately

So, convert all expenses in per year by calculating with no. of week and months,

Rent deduction = 52 weeks × R130 = R6760 per year

Transport deduction = R3 890 per year

Food, entertainment = R1 200 × 12 month = R14 400 per year

Phone and internet = R400 × 12 month = R4 800 per year

Stationary and clothers = R7 220 per year

Now lets Subtract all deduction from total salary, we get

Extras = Total salary per year - Total deduction per year

Extras = R63 420 - (R5 785 + R6 760 + R3 890 + R14 400 + R4 800 + R7 220)

Extras = R20 565

So after dudction of all expense she has extra R20565, i.e the amount she earns is enough to cover her annual expenses.

A grain silo is in the shape of a cylinder with a hemisphere top. They cylinder is 20 feet tall. The volume of the silo is 2106
andreyandreev [35.5K]

Answer:

The radius of the silo is 5.788 feet.

Step-by-step explanation:

Since the silo has the shape of a cylinder, then;

Volume of the silo = Volume of a cylinder = \pir^{2}h

Where: r is the radius of the silo, and h is the height.

Given that: volume = 2106 cubic feet, and height = 20 feet.

Then,

2106 = \frac{22}{7} x r^{2} x 20

2106 = \frac{440}{7}r^{2}

2106 x 7 = 440r^{2}

14742 = 440r^{2}

r^{2} = \frac{14742}{440}

r^{2} = 33.5045

⇒ r = \sqrt{33.5045}

     = 5.78831

r = 5.788 feet

The radius of the silo is 5.788 feet.

Solve for the sqrt(x-2)+8=x
kirza4 [7]
<h3>Answer:  x = 11</h3>

==============================================

Work Shown:

\sqrt{x-2}+8=x\\\sqrt{x-2}=x-8\\\left(\sqrt{x-2}\right)^2=(x-8)^2 \text{ square both sides}\\x-2=x^2-16x+64\\0=x^2-16x+64-x+2\\0=x^2-17x+66\\x^2-17x+66 = 0\\(x-11)(x-6) = 0\\x-11 = 0 \text{ or } x-6 = 0\\x = 11 \text{ or } x = 6\\

Those are the two possible solutions . We need to check each possible solution.

Plug in x = 11 then simplify. If we get the same number on both sides, then x = 11 is confirmed.

\sqrt{x-2}+8=x\\\sqrt{11-2}+8=11\\\sqrt{9}+8=11\\3+8=11\\11=11\\

We get 11 on both sides, so the solution x = 11 is confirmed.

Repeat for x = 6 as well

\sqrt{x-2}+8=x\\\sqrt{6-2}+8=6\\\sqrt{4}+8=6\\2+8=6\\10=6\\

We do not get the same thing on both sides, so x = 6 is not a solution. We consider this extraneous.

Calculate the discriminant: 5x² + 2x − 2 = 0
Darya [45]

Answer:

44

Step-by-step explanation:

The equation is of the form  a x ²+bx +c = 0 where

a = 5, b= -2, c= -2

The Discriminant is given by:

Δ= b²− 4  * a  *  c

=  (−2²)−  ( 4  *  5  *  ( −  2 ) )

=  4 +  40

= 44
