when will they be equal......so set them equal to each other
20 + 1.25d = 2.50d
20 = 2.50d - 1.25d
20 = 1.25d
20 / 1.25 = d

A right triangle, DEF, is shown below. What is sin FDE?

RoseWind [281]

Answer:

22.6°

Step-by-step explanation:

Reference angle = <FDE

Side opposite to <FDE = 5

Hypotenuse = 13

The trigonometric ratios to apply is:

$sin(\theta) = \frac{opp}{hyp}$

Plug in the values

$sin(\angle FDE) = \frac{5}{13}$

$sin(\angle FDE) = 0.3846$

$\angle FDE = sin^{-1}(0.3846)$

$\angle FDE = 22.6$ (nearest tenth)

$\LARGE{ \underline{\underline{ \sf{\pink{ Required\: answer:}}}}}$

<h2>GIVEN - </h2>

Water tank which is in a shape of right rectangular prism

Dimensions = 6 feet × 4 feet × 7 feet

Surface area of tank

<h2>SOLUTION - </h2>

Using formula of surface area of right rectangular prism -

Surface area =

$2(wl + hl + hw)$

L = length

w = width

h = height

( assumimg 6 feet = L , 4 feet = W , 7 feet = h)

Putting value of L, W and H in the equation. we get,

=2(4 × 6 + 7 × 6 + 7× 4)

= 2(24 + 42 + 28)

= 2( 94)

= 2 × 94

= 188

Lapatulllka [165]

Answer:

The number of ways this can be done is 1,260 ways

Step-by-step explanation:

In this question, we are asked to calculate the number of ways in which the letters of the word balloon can be arranged.

To do this, we take into consideration those letters that are repeated and the number of times repeated. The letters are l and o and are repeated two times each.

The number of ways = 7!/2!2! = 5040/4 = 1,260 ways
