Answer:

14 2/21 cm²

Step-by-step explanation:

Area = length × width

= 2 2/7 × 6 1/6

= 16/7 × 37/6

= 296/21

= 14 2/21

Answer:

11.8095238095 or 11.81

Step-by-step explanation:

The way to figure out the area of a rectangle is by multiplying the width by the length. In your case, you would multiply 5 1/6 by 2 2/7 to get 11.8095238095 but we can always round it to 11.81. I hope this helps...

Romashka-Z-Leto [24]

Answer

p/q = 8/6

Make p the subject

p = 8q/6........equation 1

This year the price was reduced by 4

p-4/q-4 = 7/5

Cross multiple

5(p-4) = 7(q-4)

5p-20 = 7q-28

5p - 7q = -8 .......equation 2

Sub 8q/6 for p in equation 1

5(8q/6) - 7q = -8

Multiply through by 6

40q-42q=-48

-2q=-48

q=24

Sub 24 for q in equation 1

p= 8(24)/6

p= 192/6

p= 32.....

Check the answer for confirmation.

Thanks.

Find f (25/29) if f (x)=-5x+5

devlian [24]

Answer:

f(25/29) = $\frac{20}{29}$

Step-by-step explanation:

In order to do this problem, we need to plug in $\frac{25}{29}$ for x. When we plug it in we get $f(x) = -5(\frac{25}{29}) + 5$ . After this we can start by multiplying. When we multiply $-5(\frac{25}{29} )$ we get $(\frac{-125}{29}) + 5$ . Since the fraction cannot be simplified any further, we can now add 5. In order to add 5 we need to find a common denominator, which in this case will be 29. Changing the denominator to 29 gives us $(\frac{-125}{29}) + \frac{145}{29}$ because when changing the denominator we have to multiply the numerator by the same number. After adding these fractions we get our answer of $\frac{20}{29}$ .
