Can I get help with this please
drek231 [11]

Answer:

3)  1 5/6 mi

4)  a. 4 cm, 6 ft

    b. 6.4 cm, 9.6 ft

    c. same as part a

Step-by-step explanation:

3) Each of the given distances appears twice in the sum of side measures that is the perimeter. Hence by walking the perimeter twice, Kyle walks each of the given distances 4 times. His total walk is ...

  4×1/3 + 4×1/8 = 4/3 + 4/8

  = 1 1/3 + 1/2 = 1 2/6 + 3/6

  = 1 5/6 . . . . . miles

___

4) Since the figure is rectilinear (all angles are right angles, and all sides are straight lines), the sum of partial dimensions in one direction is equal to the whole dimension in that direction.

a. 8 cm = 4 cm + x

  8 cm - 4 cm = x = 4 cm

The distance in the room is ...

  (4 cm)×(1.5 ft/cm) = 6 ft

b. 10.3 cm = 3.9 cm + y

  10.3 cm - 3.9 cm = y = 6.4 cm

The distance in the room is ...

  (6.4 cm)×(1.5 ft/cm) = 9.6 ft

c. The answer to part b was obtained in the same way as the answer to part a.  The unknown dimension is the difference of given dimensions. The actual length in the room is the model length multiplied by the inverse of the scale factor.

the grocery store has a special deal on potato chips where if you buy 1 bag you get the second bag for 50% off. if the sales tax
Taya2010 [7]
<span>The price for the three bags of chips is (3 x 2.50) - 2.50/2, because one of the bags will have 50% off. This makes $6.25. Divide this by 100 to find 1%, then multiply by 5 to find 5% — this tells you the amount of sales tax to add on. (6.25/100) x 5 = 0.31 to two decimal places. The final amount for the total purchase is 6.25 + 0.31 = $6.56.</span>

3. The functions f and g are defined by f: x → ax – b where a and b are constants and g: x → X+4.
valentinak56 [21]

Answer:

fg(2) = 9 means that f(g(2)) = 9

We know that g(2) = 6

So f(6) = 9 which means that

6a - b = 9 (note 1)

And we know that g(f(1/2)) = 2

And we know that f(1/2) = 1/2(a) - b

So g(1/2(a) - b) = 2

Meaning that 1/2(a) - b + 4 = 2

So 1/2(a) - b = - 2 (note 2)

Using note 1 and 2 we can solve the equation

11/2(a) = 11 so a = 2 and b = 3
