21 degrees C ????????????
Answer:
486 in³
Step-by-step explanation:
Area of base = l*b = 81sq. inches
h = 6 inches
Volume of the box = lbh = 81 * 6 = 486 cubic inches
Answer: C
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
y = mx + b
150 = 15x + 25
15x + 25 = 150
15x + 25 = 150 (el 25 se cancela)
-25 -25
15x = 125 (divide cada lado por 15) (y el 15 se cancela dejando la x sola)
15 15
x = 8.3 (pero como necesitas un numero completo lo redondeas al 10 mas sercano que seria 8)
x = 8
Answer:
-8/7
Step-by-step explanation:
First, find the slope of line c.
(x1, y1) = (9, 10)
(x2, y2) = (1, 3)
The slope formula is:
Solve for the slope using the given values:
The slope of line c is 7/8. To find the slope perpendicular to it, you need to find the negative reciprocal of that number. An example of that would be 2 and -1/2. Basically, flip the fraction and the +/-.
In this case, the negative reciprocal of 7/8 is -8/7. The image below doesn't account for the y-intercept, but it does show that the slopes are perpendicular.
