Answer:

Since x is an integer we conclude that there are 10 trucks needed to carry away 45 tones of debris.

Step-by-step explanation:

First we will find the volume of the dump truck:

V = 10*15*6.5

V = 975 ft^3

1 ton = 200 ft^3

45 tons = 45*200 ft^3

45 tons = 9,000 ft^3

Let x represent the number of trucks needed to carry away 45 tones of debris:

975*x = 9000

Answer:

10

Step-by-step explanation:

Each trailer of each truck can cart away (10)(15)(6.5) = 975 cubic feet of debris.

To cart 45 tons of debris i.e. 200 x 45 = 9000 cubic feet of debris away, we need

9000/975 = 9.23 trucks.

Since you need at least 9.23 trucks, and you cannot have a decimal number of trucks, 10 trucks are needed to cart away 45 tons of debris from a demolition site.

What is the volume of a pyramid that is 15mm , 18mm , 21mm in cubic millimeters
Ugo [173]

Answer:

V=1890mm

Step-by-step explanation:

You must use its formula: which is

V=(Length x height x width) / 3

V=(15x18x21)/3

V=5670/3

V=1890mm

If 32^2c=8^c what is the value of c? 1 2 3 5
Elina [12.6K]

Answer:

  • as written, c ≈ 0.000979 or c = 4
  • alternate interpretation: c = 0

Step-by-step explanation:

<em>As written</em>, you have an equation that cannot be solved algebraically.

  (32^2)c = 8^c

  1024c = 8^c

  1024c -8^c = 0 . . . . . . rewrite as an expression compared to zero

A graphical solution shows two values for c: {0.000978551672551, 4}. We presume you're interested in c = 4.

___

If you mean ...

  32^(2c) = 8^c

  (2^5)^(2c) = (2^3)^c . . . . rewriting as powers of 2

  2^(10c) = 2^(3c) . . . . . . . simplify

  10c = 3c . . . . . . . . . . . . . .log base 2

  7c = 0 . . . . . . . . . . . . . . . subtract 3c

  c = 0 . . . . . . . . . . . . . . . . divide by 7

Write the equation of a line that is perpendicular to y=3x-2 that passes trough the point (-9,5)
ElenaW [278]

\huge\boxed{y-5&=-\frac{1}{3}(x+9)}

First, we'll find the slope of the new line. The first line has a slope of 3. Take the negative reciprocal of this (Flip the numerator and denominator, then multiply by -1) to get -\frac{1}{3} for the new slope.

Then, we'll use the point-slope form to make the new equation, where m is the slope and (x_1,y_1) is a point on the line:

\begin{aligned}y-y_1&=m(x-x_1)\\y-5&=-\frac{1}{3}(x-(-9))\\y-5&=-\frac{1}{3}(x+9)\end{aligned}
