Answer:

Product: Iphone 6s plus box

W= 3in L= 6in H= 3in

And then use the surface area equation ( SA = 2lw + 2wh + 2lh)

To get your volume use the equation ( V = lwh)

And then divide those two SA / V and you get your ratio

Let us assume the following units of measure:
Length = 10 inches
Width = 5 inches
Height = 8 inches

Surface area = 2lw + 2wh + 2lh
S.A = 2(10in * 5in) + 2(5in * 8in) + 2(10in * 8in)
S.A = 2(50in²) + 2(40in² + 2(80in²)
S.A = 100in² + 80in² + 160in²
S.A = 340 in²

Volume = lwh
V = 10 in * 5 in * 8 in
V = 400 in³

ratio of the surface area to volume?
340 in² / 400 in³ = 34 / 40 in = 17/20 in

Explanation:

1.angels on a straight line add up to 180degrees

2.when you see the signs at number 6 and 7 it means it is 90 degrees

EG. number 6.it will be 90degrees+29degrees=119degrees remember that all angles on a straight line add up to 180 degrees. to get angel xwy you will subtract 119 degrees from 180 degrees =xwy which is 61 degrees

The algebraic expression 0.07d^3/2 describes the duration of a storm, in hours, whose diameter is d miles. use a calculator to d

Shkiper50 [21]

Answer:

1.30 hours

Step-by-step explanation:

Put the given number in the formula and do the arithmetic. The value of "d" is given as 7, so you are evaluating the expression ...

duration = 0.07×7^(3/2) . . . . put 7 where "d" is in the expression

= 0.07×18.520 . . . . . . . . . . . . evaluate 7^(3/2)

= 1.2964 . . . . . . . . . . . . . . . . . do the multiplication

≈ 1.30 . . . . rounded to hundredth

The duration of a storm 7 miles in diameter is predicted to be 1.30 hours.

With a suitable calculator, this can all be done at once.

Find the perimeter and the area of the figure.

Gwar [14]

$\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

the given figure is a composition of a rectangle as well as a right angled triangle !

we've been given the two sides of the rectangle and we're required to find out the height of the triangle , so as to find it's area ~

we know the the opposite sides of a rectangle are equal , therefore we can break the longest side ( length = 9.5 cm ) into two parts ! the first part of length = 7 cm which is the length of the rectangle and the rest 2.5 cm ( 9.5 - 7 = 2.5 ) will become the height of the triangle !

<h3>For perimeter of the figure -</h3>

$perimeter \: of \: figure = perimeter \: of \: rectangle + perimeter \: of \: triangle \\ \\$

now ,

perimeter of rectangle = 2 ( l + b )

where ,

l = length

b = breadth

$\longrightarrow \: perimeter = 2(7 + 6) \\ \longrightarrow \: 2(13) \\ \longrightarrow \: 26 \: cm$

and ,

$perimeter \: of \: \triangle = 6.5 + 2.5 + 6 \\ \longrightarrow \: 15 \: cm$

Perimeter of figure in total = 26 cm + 15 cm

thus ,

$\qquad\quad\bold\red{perimeter \: = \: 41 \: cm}$

<h3>For area of the figure -</h3>

$area \: of \: figure = area \: of \: rectangle + area \: of \: rectangle \\$

now ,

area of rectangle = l × b

where ,

l = length

b = breadth

$area \: of \: rectangle = 7 \times 6 \\ \longrightarrow \: 42 \: cm {}^{2}$

and ,

$area \: of\triangle = \frac{1}{2} \times base \times height \\ \\ \longrightarrow \: \frac{1}{\cancel2} \times \cancel6 \times 2.5 \\ \\ \longrightarrow \: 3 \times 2.5 \\ \\ \longrightarrow \: 7.5 \: cm {}^{2}$

Area of figure in total = 42 cm² + 7.5 cm²

thus ,

$\qquad\quad\bold\red{Area \: = \: 49.5 \: cm^{2}}$

hope helpful :)
