Answer:

125 meters squared

Step-by-step explanation:

Surface area of initial pyramid:

  • A= 10²+4*1/2*10*15= 400 m²

Surface area of extended pyramid:

  • A= 10*15+2*1/2*15*15+2*1/2*10*15= 525 m²

The difference is:

  • 525- 400= 125 m²

What is the y-intercept of the line passing through the point (9-7) and has a slope of -1/8
Lina20 [59]
Y - y1 = m(x - x1)
y + 7 = (-1/8)(x - 9)
y + 7 = (-1/8)x + 1.125
Subtract 7 from both sides
y = -1/8x - 5.875

Solve the one step equations- 3.7+w=9.24
mariarad [96]
<span>Simplifying -3.7 + w = 9.24 Solving -3.7 + w = 9.24 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '3.7' to each side of the equation. -3.7 + 3.7 + w = 9.24 + 3.7 Combine like terms: -3.7 + 3.7 = 0.0 0.0 + w = 9.24 + 3.7 w = 9.24 + 3.7 Combine like terms: 9.24 + 3.7 = 12.94 w = 12.94 Simplifying w = 12.94</span>

12x + 2y =6a. solve for yb. what is the slope and what is the y-intercept?
diamong [38]

The equation of a line in the slope intercept form is expressed as

y = mx + c

where

m represents slope

c represents y intercept

The given equation is

12x + 2y = 6

we would make this equation to look like the slope intercept equation.

12x + 2y = 6

If we subtract 12x from both sides of the equation, it becomes

12x - 12x + 2y = 6 - 12x

2y = 6 - 12x

2y = - 12x + 6

Dividing both sides of the equation by 2, it becomes

y = - 6x + 3

Thus, by comparing with the slope intercept equation,

slope = - 6

y intercept = 3

One warehouse had 185 tons of coal, another one had 237 tons. The first warehouse delivered 15 tons of coal to its clients daily
lianna [129]

Answer:

In 9 days will the second warehouse have 1.5 times more coal than the first one

Step-by-step explanation:

The coal left in warehouses after x days can be found using the equation:

  • first warehouse: 185 - 15x
  • second warehouse= 237-18x

Let the second warehouse have 1.5 times more coal than the first one after n days then  

  1. 1.5 ×(185 - 15n)=237-18n  which gives:
  2. 277,5-22,5n=237-18n and
  3. 40,5=4,5n
  4. 9=n
