This works when it is not close to noon
put the yardstick next to the pole
measure the shadow of the pole, call it x
measure the letngh of the shadow of the yardstick
measure the height of the yardstick

the ratio of the height of the yardstick to the shadow of the yardstick should be close to the ratio of the height of the pole to the legnth of the shadow of the pole

You need 4/5 cups of strawberriers to make 1 pie how much cups will u need to make 2 pies
Annette [7]

Answer:

1 \frac{3}{5} cups of strawberries

Step-by-step explanation:

To find how much you will need for 2 pies, multiply 4/5 by 2:

4/5(2)

= 8/5

Simplify this to a mixed number:

= 1 \frac{3}{5}

So, you will need 1 \frac{3}{5} cups of strawberries to make 2 pies

Help me with my geometry please
Sergio [31]

Answer:

see explanation

Step-by-step explanation:

the exterior angle = 180° - interior angle

(17)

exterior angle = 180° - 144° = 36°

The sum of the exterior angles of a polygon = 360°

Hence the number of sides n is

n = \frac{360}{36} = 10

(18)

exterior angle = 180° - 156° = 24°

n = \frac{360}{24} = 15

(19)

exterior angle = 180° - 160° = 20°

n = \frac{360}{20} = 18

In the following 2 questions we are using that the sum of the interior angles of a quadrilateral is 360°

(20)

summing the angles and equating to 360

2x + 15 + 3x - 20 + x + x + 15 = 360

7x + 10 = 360 ( subtract 10 from both sides )

7x = 350 ( divide both sides by 7 )

x = 50

∠J = 2x + 15 = 100 + 15 = 115°

∠K = 3x - 20 = 150 - 20 = 130°

∠M = x = 50°

∠N = x + 15 = 50 + 15 = 65°

(21)

6x - 4 + 2x + 8 + 6x - 4 + 2x + 8 = 360

16x + 8 = 360 ( subtract 8 from both sides )

16x = 352 ( divide both sides by 16 )

x = 22

∠R = ∠T = 6x - 4 = 132 - 4 = 128°

∠S = ∠U = 2x + 8 = 44 + 8 = 52°

Cade covered the outside of a box shaped like a rectangular prism with paper. The box is 3.5 feet long, 2.2 feet wide, and 4.1 f
Orlov [11]

Answer:

The total surface area of this box is  62.14 square feet

Step-by-step explanation:

Given:

Length = 3.5 feet

Width  =  2.2 feet

Height =  4.1 feet

To Find:

The Surface area of the prism = ?

Solution:

The box is the shape of rectangular prism

Then the surface area of the prism = 2(lh +hw +wl)

Where

l is the length

w is the width

h is the height

Substituting the values

The surface area of the prism =2((3.5 \times  4.1) +(4.1\times + 2.2) +(2.2 \times 3.5))

The surface area of the prism = 2(14.35 + 9.02 + 7.7)

The surface area of the prism = 2(31.07)

The surface area of the prism = 62.14 square feet
