Answer:

  • 41 cm and 166 cm

Step-by-step explanation:

<u>As per question we have:</u>

  • 2(l + w) = 414 ⇒ l + w = 207
  • l = 5w - 39

<u>Solve it for l by substitution:</u>

  • 5w - 39 + w = 207
  • 6w = 207 + 39
  • 6w = 246
  • w = 246/6
  • w = 41

<u>Find l:</u>

  • l = 207 - 41 = 166

Moses has a bakery, and he is expecting a new shipment of flour today.
rjkz [21]

Answer:

I = 60 + 18k

Step-by-step explanation:

Data provided in the question:

The function for number of  loaves, N that Moses bake

⇒ N(k) = 10 + 3k

here,

k is the kilograms of floor received

and,

Income in dollars, I(x) = 6x

here, x is the number of loaves baked

thus,

when k kilograms of flour is received,

x = N(k) = 10 + 3k

substituting x in income function,

we get

I = 6(10 + 3k)

or

I = 60 + 18k

A dinner platter is in the shape of a regular decagon. The platter has an area of 161 square inches and a side length of 4.6 inc
REY [17]

When I saw this, I said to myself  "Self !  We don't know anything about
decagons.", and then I went searching online for stuff about decagons.
This just goes to show how stupid I can be when I don't take a little time
to THINK before I go running around screaming.

-- When you draw all the lines from the center to the vertices of the
decagon, you'll have 10 little triangles.

-- The area of the whole thing is 161 square inches, so the area of each
little triangle is 1/10 of that . . . . . <em>16.1 square inches</em>.

-- The area of each little triangle is  (1/2) (base) (height), just like
every other triangle.
The base is the 4.6 inches of one side of the decagon.
              
                                                  Area = (1/2) (base) (height)

Multiply each side by 2:         2 x area = (base) x (height)

Divide each side by (base):  (2 x area) / (base) = height

                              Height = (2 x 16.1) / (4.6) =  <em>7 inches</em> .

Let that be a lesson to both of us.
THINK before you jump.
