Answer:

108 inches square.

Step-by-step explanation:

Here

base= b= 4 inches

height = h=w=  3.5 inches

and length = l= 9  inches

The surface area is the total area of all the sides of the prism. So the area of the 2 triangles is given by

Area of the 2 Δs= b* h= 4*3.5=  13.5 inches square

Area of the 3 rectangles = l*w(3)= 3( 9*3.5)= 94.5  inches square.

Total area = 13.5 + 94.5 = 108 inches square

This can be found by applying another formula.

Surface area of the triangular prism = bh + ( s1+s2+s3) H

                                                         = 4*3.5 + (9+9+9)3.5

                                                          = 13.5 + 94.5= 108 inches square.

where H is the width of the recatngles which is equal to the height of the triangles.

Answer:

Step-by-step explanation:

First use distributive property: a(b + c) = a*b + a*c

3n - 6 = -8(6 + 5n)

3n - 6 = 6 * (-8) + 5n *(-8)

3n - 6 = -48 - 40n

Now add 40n to both sides

3n - 6 + 40n = -48 - 40n + 40n

43n - 6 = -48

Now add 6 to both sides

43n - 6 + 6 = -48 + 6

           43n = -42

               n = -42 /43

Answer:

0.98

Step-by-step explanation:

3n-6=-8(6+5n)

3n-6=-48-40n

3n=-48-40n+6

40n+3n=-42

43n=-42

n=0.98 (I rounded it)

Answer:

12 ¼

Step-by-step explanation:

if you add the 16ths its up to 4 16ths, simplified that is ¼. then you add the 3s, 3 × 4 is 12. add the two, 12 ¼

Answer:

No, the triangles are not similar.

Step-by-step explanation:

For ΔNOP, since all triangles' angles equal 180°, to find the missing angle you subtract the given angles from 180

180-70=110, 110-58=52       ∠N = 52°

since ΔQRS does not have any angle measures of 58° or 52°, the triangles are not similar becasue similar triangles have congruent angles.

Answer:

The value of x is approximately 5

Step-by-step explanation:

Answer:

x=6.36

Step-by-step explanation:

In a right triangle where the angles are 45, 45 and 90, the hypotenuse is equal to [tex]\sqrt{2}[/tex] multiplied by the length of the legs. Knowing this, we can set up the following equation:

[tex]9=x\sqrt{2}[/tex]

Multiply both sides by [tex]\sqrt{2}[/tex]

[tex]9\sqrt{2} =x\sqrt{2}*\sqrt{2}\\9\sqrt{2} =2x[/tex]

Divide both sides by 2

[tex]\frac{9\sqrt{2}}{2}=\frac{2x}{2}\\\frac{9\sqrt{2}}{2}=x[/tex]

[tex]x=6.36[/tex] (this answer is approximate)

Therefore, x is equal to 6.36.

Answer:

2.5x + 20 = y

Step-by-step explanation:

first, assign a variable to each unknown:

since we don't know how many videos were rented, that can be x, and we don't know the person's total cost, which can be y

x = number of videos rented

y = total cost

so there's always a $20 that's added on as a membership fee, which means that theres going to be a + 20 somewhere.

So, the equation is 2.5x + 20 = y

Answer:

8 feet squared

Step-by-step explanation:

The area of bedroom 1 is 2 length and 3 width. multiply them and you get 6ft^2 plus the 2 squares on the right.

The area of Bedroom 1 is,

⇒ 32 feet²

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

To find square feet of flooring are needed to cover the entire floor of Bedroom 1.

Here, We have;

1 in = 4 feet

Hence, Length of bedroom 1 = 8 feet

Width = 4 feet

Thus, The area of Bedroom 1 is,

⇒ 8 x 4 = 32 feet²

Hence, The area of Bedroom 1 is,

⇒ 32 feet²

Answer:

2. 19.47 in

3. 153.86 square centimeters

Step-by-step explanation:

2. The circumference of a circle is π times the diameter, so in this case it is 6.2 * 3.14 = 19.47 in (rounding to nearest hunderdth).

3. The area of a circle is π/4 times the diameter squared, so in this case it is 14^2 * 3.14 / 4 = 153.86 square centimeters.

glow bowling costs $0.75 more per game

Step-by-step explanation:

1. divide $22.50 by 5 games to find the price per game for glow-bowling, which comes out to $4.50

2. divide $30.00 by 8 games to find the price per game for the early-bird special, which comes out to $3.75

3. subtract $3.75 (early-bird bowling) from $4.50 (glow-bowling) and it = $0.75
