Answer:

O = 4 Diamond = 18 Δ = - 5

Step-by-step explanation:

The O is 4 because in clue 2 we see that 3 x 4 = 12

Now we can solve clue 1.

Diamond + 2 = 5 * O

Diamond + 2 = 5 * 4

Diamond + 2 = 20 Subtract 2 from each side

Diamond = 20 - 2

Diamond = 18

And now we can solve clue 3 for the Δ

2 * O = Diamond + 2 * Δ

2 * 4 = 18 + (2 * Δ)

8 = 18 + (2 * Δ) Subtract 18 from both sides.

8 - 18 = (2 * Δ)

- 10 = (2 * Δ) Divide each side by 2

- 10 / 2 = (2 * Δ) / 2 The 2 on the right will cancel

- 10 / 2 = Δ

-5 = Δ

So O = 4 Diamond = 18 Δ = - 5

Lera25 [3.4K]

Answer:

$A = 68.8 inches^{2}$

Step-by-step explanation:

Given : Jennifer got a box of chocolates. the box is a right triangular prism shaped box. it is 7 in long. and the triangular base measure 2in times 3in times 4in.

a = 2

b=3

c=4

To Find : what is the surface area of the box of chocolates?

Solution: The first thing we should know is the area of the triangular base.

Triangular base area:

$A1 =\sqrt{(s * (s-a) * (s-b) * (s-c)) }$

Where, s is the semi-meter of the triangle:

$s =\frac{ (a + b + c) }{ 2}$

a, b, c: sides of the triangle.

Substituting:

s = (2 + 3 + 4) /2=4.5

$A1 = \sqrt{ (4.5 * (4.5-2) * (4.5-3) * (4.5-4))}$

A1 = 2.90

Then, you must know the area of each rectangle associated with each side of the triangular base.

Rectangle area 1: Ar1 = (a) * (l)

Ar1 = (2) * (7)

Ar1 = 14

Rectangular area 2: Ar2 = (b) * (l)

Ar2 = (3) * (7)

Ar2 = 21

Rectangular area 3: Ar3 = (a) * (l)

Ar3 = (4) * (7)

Ar3 = 28

Finally the surface area is: A = Ar1 + Ar2 + Ar3 + 2 * A1

A = (14) + (21) + (28) + 2 * (2.90)

$A = 68.8 inches^{2}$

Hence the surface area of the box of chocolates is

$A = 68.8 inches^{2}$

Answer: I’m wasnt sure if u r supposed to round up. I assumed that we round down at the hundredth decimal cuz money. Also, make sure to include money signs when you write the numbers down.

A. 42.57

b. 50.96

C. 49.44

D. 63631.44

E. 127.05

F. 3805.49

G. 3.76

H. 2687.61

I. 9526.21

J. 3453.78

Step-by-step explanation:

A. 30 x 1.419= 42.57

B. 45 x 1.13250= 50.9625

C. 56/ 1.13250= 49.44812362

D. 478.90 x 132.87= 63631.443

E. 89.54 x 1.419= 127.05726

F. 5400/ 1.417= 3805.49682875

g. 500/ 132.87= 3.76307669

H. 4500/ 1.67435= 2687.61011735

i. 5689.50 x 1.67435= 9526.214325

I give brainalist and points for an answer and explanation

irina [24]

Answer:

option D

Step-by-step explanation:

diameter of two small circle i.e 14cm

radius of two small circle =7cm

area of the small circle =πr²

area of the small circle=22/7 x7²

area of the small circle=154cm²

Radius of bigger circle =14cm
Area of bigger circle=πr²

Area of bigger circle=22/7×14²

Area of bigger circle=616cm²

Area of shaded region =area of bigger circle -area of small circle +area of small circle

area of shaded region =616-154+154

area of shaded region=308cm²

i.e approximately 282.74cm²
