3 + 1.2 x > 13.50
can someone please help me

Answers

Answer:

The answer is x > 8.75.

Step-by-step explanation:

1) Subtract 3 from both sides.

[tex]1.2x > 13.50 - 3[/tex]

2) Simplify 13.50 - 3 to 10.5.

[tex]1.2x > 10.5[/tex]

3) Divide both sides by 1.2.

[tex]x > \frac{10.5}{1.2} [/tex]

4) Simplify 10.5/1.2 to 8.75.

[tex]x > 8.75[/tex]

Thus, the answer is x > 8.75.

A cash withdrawal of R5000 was made at signet blue on the 20/05/2019.Calculate what percentage the withdrawal fee is of the transaction amount

Answers

Answer: 1%

Step-by-step explanation:

Question is incomplete as it lacks the details of the withdrawal fee.

We shall assume one so that we can use it for calculation so that you can understand the methods.

Assume withdrawal fee of R50.

The withdrawal amount was R5,000 and the cost to withdraw was R50.

The percentage of the withdrawal fee in relation to the total amount is:

= Withdrawal amount / Total amount * 100%

= 50 / 5,000 * 100%

= 1%

If you use sin- you get 0.5 but if you round it I’m pretty sure it rounds to 0.6. I put 4 divided by 8 then sin (90) in my calculator and got 0.5. It’s 90° because it’s a right triangle. So I think the answers 0.6 since there’s no 0.5 option. I’m hoping that helped!! Lol

Carl's baseball team is selling
trash bags to raise money for
uniforms and equipment. Each
player starts with a credit of $50
towards their sales, and each roll of
trash bags sells for $8. Determine
how many rolls of trash bags each
person must sell to make $300.

Answers

Answer:

32

Step-by-step explanation:

One member would make 250$ by selling 31.25 rolls. Which if you round up you get 32. You can't sell a quarter of a roll so you must go up one therefore the answer is one person must sell 32 rolls in order to make 300$ including the 50$ already towards his credit.

Answer:

area = 57√3 cm²

Step-by-step explanation:

lower polygon:

14-8 = 6, 6/2 = 3

3 is the base of the lower left triangle

cos 60° = 3/hypotenuse

hypotenuse = 6

height of triangle² = 6² - 3² = 45

height of triangle² = 36 - 9 = 27

height of triangle = √27 = √(9 x 3) = 3√3

area of lower polygon = 1/2(8+14)(3√3) = 33√3 cm²

upper parallelogram:

area = 8(3√3) = 24√3 cm²

total area = 24√3 + 33√3 = 57√3 cm²
