A rectangular prism measures 5 m by 8 m by 9 m. If the dimensions of the box were all halved, how would the surface area of the box change?

Answer:

91

Step-by-step explanation:

given perimeter = 273

perimeter of equilateral triangle = 3a

3a = 273

a = 273/3

a = 91

hence, length of side of the triangle is 91

Answer:

[tex]\sf \boxed{\sf volume=\frac{16}{9} \ ft^3}[/tex]

Explanation:

Cube volume: Length x Width x Height

Volume of the entire cuboid:

Length x Width x Height

(1/3 x 4) x (1/3 x 3) x (1/3 x 4)

4/3 x 1 x 4/3

16/9

Volume of the cuboid

Answer:

16:3

Step-by-step explanation:

Thats the way ratios work

y=-2x+5

First of all we need to determine the slope of the line perpendicular to y = 1/2x - 5 .

The slopes of perpendicular lines are opposite reciprocals.

So we take 1/2 , turn it over , and change it's sign :

[tex]^1/_2\:\:\:--- > ^2/_1\:\:\:--- > 2\:\:\:--- > -2[/tex]

The slope of the line perpendicular to y = 1/2x-5 is -2 .

Since we're also given a point that the line crosses , we can write the line's equation in point - slope form :

y-y₁=m(x-x₁)

y-7=-2(x-(-1)

y-7=-2(x+1)

Now convert to slope intercept :

y-7=-2x-2

add 7 on both sides :

The sum of the interior angles of a triangle = 180

so

(180-124)   +  (180-6x)   +  2x = 180

x = 14

Answer:

  5,450,000

Step-by-step explanation:

The population can be modeled by an exponential function with a growth rate of 1% per month. The time of interest, 5 years, is 60 months.

__

  population = (initial value) × (1 + growth rate per month)^(months)

  p = 3,000,000 × (1.01^60) . . . . . . population in 60 months

  p ≈ 5,450,000 . . . . in 5 years

The estimated population of rats in nyc is about 5,450,000 in 5 years.

Answer:

12/35

Step-by-step explanation:

tan = opposite side / addjesent side

Tan (A) = 12 / 35

The size of the angle QUP in the system formed by the equilateral triangle QUR, the equilateral triangle PUT and the square RUTS is equal to 150°.

By Euclidean geometry we know that squares are quadrilaterals with four sides of equal length and four right angles and triangles are equilateral when its three sides have equal length and three angles with a measure of 60°. In addition, a complete revolution has a measure of 360°.

Finally, we must solve the following equation for the angle QUP:

m∠QUR + m∠QUP + m∠PUT + m∠RUT = 360

60 + m∠QUP + 60 + 90 = 360

m∠QUP + 210 = 360

m∠QUP = 150

The size of the angle QUP in the system formed by the equilateral triangle QUR, the equilateral triangle PUT and the square RUTS is equal to 150°. [tex]\blacksquare[/tex]

Step-by-step explanation:

step-by-step explanation: so ( x-2y)^7 expanded is: x^7-14 x^6y+84x^5y^2-280x^4y^3+560x^3 y^4-672x^2y^5+448xy^6-128y^7. The x^4y^3 term would then be -280 x^4y^3,meaning the coefficient (the number before the variables) here is 280

Step-by-step explanation:
To calculate a rectanglars prism all you have to do is multiply the length, width and height together.

There are many things happening on the streets and some of them are bad. There is a high likelihood that if you are on the streets you will see bad things happening.

Answer:

b

Step-by-step explanation:

the volume (V) of a cone is calculated as

V = [tex]\frac{1}{3}[/tex]πr²h ( r is the radius , h is the height )

here diameter = 12 , so r = 12 ÷ 2 = 6 and h = 22 , then

V = [tex]\frac{1}{3}[/tex]π × 6² × 22

   = [tex]\frac{1}{3}[/tex]π × 36 × 22

    = [tex]\frac{1}{3}[/tex]π × 792 ( cancel 3 and 792 by 3 )

    = π × 264

    ≈ 829.4 m³ ( to the nearest tenth )

Answer:

Let's use the formula for the volume of a rectangular prism;

V = l · w · h

Where 'l' represents the length, 'w' stands for the width, and 'h' displays as the height. (V evidently stands for the volume)

What we know:

What we need to find out:

Let's plug in what we know into the formula:

V = l · w · h

240 = 4 · 4 · h

Now let's solve for h:-

240 = 16 · h

240 = 16h

Get rid of h's co-efficient by dividing 16 from both sides because the inverse operation of multiplication(since 16 is being multiplied by h) is division.

÷16    ÷16

Finally, you would end up with a result of:

15 = h

Hence, the height of this prism is 15 feet.

Answer:

203.67

Step-by-step explanation:

all those numbers are confusing, but this is what i get from the picture

triangle area formula = 1/2 base * height

rectangle area formula = L * W

AB = 1/2 base * height, = 1/2 * 9 * 4, = 18

ab is the same as AB                        =18

C = 8.1 * 4.5                                      = 36.45

D = 8.1 * 7.2                                        = 58.32

E = 8.1 * 9                                          = 72.9

added together = 203.67

Answer:

-18

Step-by-step explanation:

1. Subtract 7 from both sides:

13x = -234

2. Divide 13 from both sides:

13x/13 = -234/13

x = -18

Answer: 60 square inches

Step-by-step explanation:

Answer:

66 square inches

Step-by-step explanation:

10 times 6 equals 60 and 60 plus 6 is 66. You add the six because that is the area of the triangle and you get 60 from multiplying 10 and 6 because that is the area of the rectangle.
