Step-by-step explanation:
(2 × 1/2 × 20 × 15) + (16 ×15) + (20 × 16) + (25×16)
300 + 240 + 320 + 400 = 1260 ft²
Use the greater simbol because 0.26 is larger than 0.4
Answer:
115.5 cm cubed
Step-by-step explanation:
The volume of a prism is found using V = l*w*h where l = 3.5, w = 6, and h = 5.5. Substitute the values and simplify.
V = 3.5*6*5.5 = 115.5
Answer:
58.3
Step-by-step explanation:
58.3 has the highest unit (the number left of the dot)
Answer:
y = - 3x + 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
x - 3y = 3 ( subtract x from both sides )
- 3y = - x + 3 ( divide all terms by - 3 )
y =
x - 1 ← in slope- intercept form
with slope m = ![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= - 3, then
y = - 3x + c ← is the partial equation
To find c substitute (5, - 9) into the partial equation
- 9 = - 15 + c ⇒ c = - 9 + 15 = 6
y = - 3x + 6 ← equation of perpendicular line
