Spot eats of a can of dog food each day

Mathematics
1 answer:
Anit [1.1K]3 years ago
6 0

Answer:

$110

Step-by-step explanation:

First we would need to find out how many cans of dog food are required.

To find that you would divide 60 by 3.

60/3 = 20

You would then have to multiply that number by how much it costs for each pair of 3 cans, that being $5.50.

20 * 5.50 = $110

Multi-step K is the midpoint of JL, JL=4x-2, and JK=7. Find x, KL, and JL
ddd [48]
If K is midpoint of JL then JK = 0.5JL

JL = 4x - 2; JK = 7

The equation:
0.5(4x - 2) = 7
2x - 1 = 7      |add 1 to both sides
2x = 8        |divide both sides by 2
<u>x = 4</u>

<u>JL</u> = 4(4) - 2 = 16 - 2 = <u>14</u>

<u>KL</u> = JK =<u> 7</u>

What is the scale factor, perimeter ratio, surface ratio, and the volume ratio?????????????????????????????
tamaranim1 [39]

Answer:

Scale factor = \frac{4}{9}

Perimeter ratio = 4 : 9

Surface area ratio = 16 : 81

Volume ratio = 64 : 729

Step-by-step explanation:

Volume ratio = \frac{\text{volume of small prism}}{\text{Volume of large prism}}

                      = \frac{128}{1458}

                      = \frac{64}{729}

                      = 64 : 729

Scale factor = \sqrt[3]{\frac{\text{volume of small prism}}{\text{Volume of large prism}}}

                    = \sqrt[3]{\frac{64}{729}}

                    = \frac{4}{9}

Perimeter ratio = Scale factor

                         = \frac{4}{9}

                         = 4 : 9

Surface area ratio = (Scale factor)²

                              = (\frac{4}{9})^{2}

                              = \frac{16}{81}

                              = 16 : 81

Tara uses:

  • 1 \dfrac{1}{4}\ kg=1 \ kg\ 250 \ g=1250\ g of rice
  • 500 g of vegatables
  • 410 g of meat

In total, Tara uses

1250+500+410=2160\ g of ingredients.

She is making dinner for 9 people, so the weight of each serving is

2160:9=240\ g
