The inches of wooden stick required to outline the perimeter of the banner in order to attach the interior material is 42 inches.

<h3>Perimeter of a triangle</h3>

The perimeter of a triangle is the sum of the whole three sides.

Therefore, the perimeter of the triangle can be found by adding the whole sides of the triangle.

The remaining sides of the triangle can be found using Pythagoras theorem.

c² = a² + b²

where

a and b are the legs

c = hypotenuse

Therefore,

a² = 13² - 5²

a² = 169 - 25

a = √144

a = 12 inches

Therefore,

b² = 15² - 12²

b² = 225 - 144

b = √81

b = 9 inches

Therefore,

perimeter = 13 + 15 + 5 + 9 = 42 inches

Therefore, the inches of wooden stick required to outline the perimeter of the banner in order to attach the interior material is 42 inches.

Use substitution to solve each of the following pairs of simultaneous equations.

Ronch [10]

Answer:

I will go for a part the rest You can do by yourself

Step-by-step explanation:

Multiply the second equation to get same amount of x in both equations

2x=2-3y/2

multiply both equations by 2 to get rid of the fraction in second equation

4x+14y=34

4x=4-3y

subtract equation(2) from equation(1)

14y=30+3y

11y=30

y=30/11, x=-23/22

Kindly i need solution of these both parts a and b which are attached below

Answer:

a) 252 cm³, 252 cm², 705.6 g

b) 240 cm³, 252 cm², 672 g

Step-by-step explanation:

The volume of each figure can be computed as the product of the base area (the side facing the viewer) and the "height" of the prism (the distance between bases).

The surface area of the prism is the sum of the two base areas and the "lateral area" consisting of the product of the base perimeter and the "height" of the prism.

The mass will be the product of volume and density.

ai) The base is a 3 cm by 8 cm rectangle together with a trapezoid with bases 3 cm and 6 cm, and height 7 - 3 = 4 cm.

B = (3 cm)(8 cm) +(1/2)(3 cm +6 cm)(4 cm) = 24 cm² +18 cm² = 42 cm²

The "height" is 6 cm, so the volume is ...

V = Bh = (42 cm²)(6 cm) = 252 cm³

aii) The perimeter of the base is the sum of its side lengths. Clockwise from left, the lengths are ...

(8 +3 +2 +5 +3 +7) cm = 28 cm

Then the lateral area is ...

LA = Ph = (28 cm)(6 cm) = 168 cm²

Adding this to the areas of the two bases, we get the total surface area:

A = LA +2B = (168 cm²) + 2(42 cm²) = 252 cm²

aiii) The mass is the product of volume and density:

M = ρV = (2.8 g/cm³)(252 cm³) = 705.6 g

____

bi) This trapezoidal prism has a base that has bases of 6 and 9 cm, and a height of 4 cm. The area of the base is ...

B = (1/2)(b1 +b2)h = (1/2)(6 cm + 9cm)(4 cm) = 30 cm²

Then the volume is ...

V = Bh = (30 cm²)(8 cm) = 240 cm³

bii) The lateral area is the perimeter of the base times the height of the prism:

LA = Ph = (4 +6 +5 +9 cm)(8 cm) = 192 cm²

The total area is this area plus that of the two bases:

A = LA +2B = (192 cm²) +2(30 cm²) = 252 cm²

biii) M = ρV = (2.8 g/cm³)(240 cm³) = 672 g

Ellen deposits $6,773 into an account earning 1% annually, After seven years what will Ellen's balance have grown to, including

lara31 [8.8K]

<span>If Ellen deposited 6 773 dollars in her account and did not withdraw any amount for 7 years.
Then she will earn this amount.
=> 1% interest rate per year
=> first year = 6 773 x .01 = 67.73
=> 6773 + 67.73 = 6840.73
=> Second year = 6840.76 * .01 = 68.4073
=> 68.4073 + 6840.76 = 6909.1673
=> Third year = 6909.1673 * .01 = 69.09
=> 6909.1673 + 69.09 = 6978.26
=>4th year = 6978.26 * .01 = 69.78
=> 6978.26 + 69.78 = 7004
=> 5th year = 7004 *.01 = 70.04
=> 7004 + 70.04 = 7074.04
=> 6th year = 7074.04 * .01 = 70.74
=> 70.74 + 7074.04 = 7144.78
=> 7th year = 7144.78 *.01 = 74.45
=> 7144.78 + 74.45 = 7216.23</span>
