tigry1 [53]3 years ago

Answer:

Area of cardboard required = 468 cm²

Step-by-step explanation:

Area of the cardboard required = Surface area of the triangular prism

Surface area of the triangular prism = Area of the lateral sides + Area of the triangular sides

Area of the one triangular side = \frac{1}{2}(\text{Base)}(\text{Height})

                                                    = \frac{1}{2}(12)(9)

                                                    = 54 cm²

Area of lateral sides = Perimeter of the triangular base × Height

Perimeter of the triangular base = 9 + 12 + 15

                                                     = 36 cm

Now area of the lateral sides = (36) × 10

                                                = 360 cm²

Surface area of the prism = 360 + 2(54)

                                          = 360 + 108

                                          = 468 cm²

Therefore, area of cardboard required for each box = 468 cm²

at the grocery store avocados can be purchased in a package of 6 for 11.10. of they are purchased separately each avocado cost 2
Romashka-Z-Leto [24]

The percentage mark up when purchasing avocados individually is 77.08%

Data;

  • 6 avocado = 11.10
  • cost of 1 avocado = 2.40

<h3>Percentage Mark up</h3>

To find the percentage mark up of one avocado, let's find the price of one avocado in 6 package of avocado.

6 avo = 11.10\\1 avo = x\\x = \frac{11.10}{6} \\x = 1.85

The percentage mark up can be calculated as

\% mark up = \frac{1.85}{2.40} * 100  = 77.08\%

The percentage mark up when purchasing avocados individually is 77.08%

HELP ASAP!!!
Gennadij [26K]

Answer:

-7

Step-by-step explanation:

The line (y-1)=(2/3)(x+1) contains point (a,-3)

=> (-3-1) = (⅔)(a+1)

-4 = (⅔)(a+1(

(a+1)= -4 ÷ ⅔

a + 1 = -4 × 3/2

a+ 1 = -6

a = -6-1

a = -7

Nikolay [14]

Answer:

a) 12 + 0.5d               d=day

b) 0.195/0.5=0.39d

Step-by-step explanation:

Answer

(a) Find out the  a rule to describe the function.

To prove

Let us assume that the days be represted by d .

Let us assume that the height of plant be represted by y.

As given

A zucchini plant in Darnell’s garden was 12 centimeters tall when it was first planted.

it has grown approximately 0.5 centimeter per day.

Than the function becomes

y = 12 + 0.5 × d

y = 12 + 0.5d

(b) Find out after how many days will the zucchini plant be 0.195 meter tall .

To prove

Let us assume that the days be represted by d .

As given

A zucchini plant in Darnell’s garden was 12 centimeters tall when it was first planted.

it has grown approximately 0.5 centimeter per day.

As

1meter = 100cm

0.195 meter convert into centimeter.

= 19.5cm

Than the equation becomes

12 + 0.5d = 19.5

0.5d = -12 + 19.5

0.5d = 7.5

d = 15 days

Therefore 15 days will the zucchini plant be 0.195 meter tall .
