Find the exact value of the expression: -6 3/5 - (-7 4/15) + 2 1/5

Answers

Answer:

Step-by-step explanation:

-6 3/5 - (-7 4/15) + 2 1/5

Combine the first and third terms first

-6 3/5 + 2 1/5 = - 4 2/5

Now deal with the second term

- (- 7 4/15) = 7 4/15

7 4/15 - 4 2/5      

7 4/15 - 4 6/15           Add 15/15 to 7 4/15 Subtract 1 from the 7

6 19/15 - 4 6/15

Find the hypotenuse of a right triangle that has a 13cm leg and a height of 7cm

Answers

Answer:

14.76 cm

Step-by-step explanation:

Use the pythagorean theorem:

a² + b² = c²

Plug in the side lengths and solve for c:

7² + 13² = c²

49 + 169 = c²

218 = c²

14.76 = c

So, the hypotenuse is approximately 14.76 cm

help solve please!!!!

Answers

Answer:

60 squared cm

Step-by-step explanation:

If half of the top of the shape is 3, that means the whole top is 6.

6 x 10 = 60

Area = Length x Width

So, 3cm is only half so I think it would have to be changed to 6cm to be the full width. Then, is length X width, so 6 X 10 meaning it would be 60cm^2, I think.

Find the total package price from each store and then calculate how much you"lol save if you purchase the less expensive package

Answers

Complete Question:

You're planning to buy a new computer, monitor, and printer for your office. You've received the following prices from two stores:

Store 1                                                        Store 2

Computer: 2,500                                     Computer: 2,350

Monitor: 595                                            Monitor: 435

Printer: 398                                              Printer: 349

Find the total package price from each store and then calculate how much you'll save if you purchase the less expensive package.

Answer:

[tex]Total = 3493[/tex] --- Store 1

[tex]Total = 3134[/tex] --- Store 2

[tex]Saved = 359[/tex]

Step-by-step explanation:

From store 1, the total cost is:

[tex]Total = 2500 + 595 + 398[/tex]

[tex]Total = 3493[/tex]

For store 2, the total cost is

[tex]Total = 2350 + 435 + 349[/tex]

[tex]Total = 3134[/tex]

By comparison: It is cheaper to buy from store 2

Because [tex]3134 < 3493[/tex]

Amount saved is calculated by subtracting the cheaper cost from the expensive cost:

i.e.

[tex]Saved = 3493 - 3134[/tex]

[tex]Saved = 359[/tex]
