The answer is 6.4 x 8 in.
The scale 5 : 4 means that the old photo is 5 and the new photo is 4.
Now, let's find the new dimensions using the proportion for each side separately.
5 : 4 = 8 : x
x = 4 * 8 : 5
x = 6.4 in
_____
5 : 4 = 10 : y
y = 4 * 10 : 5
y = 8 in
Answer:
37.68
Step-by-step explanation:
the radius is half of the circle, u multiplied by two to get the diameter and then multiply by 3.14 (pi)
Answer:
23 Pa
Step-by-step explanation:
According to ideal gas law, PV = nRT. If V is constant, then:
P/T = P/T
Remember that P and T are absolute. So °F must be converted to either Rankine or Kelvin.
To convert °F to Rankine, add 459.67.
30°F + 459.67 = 489.67 R
80°F + 459.67 = 539.67 R
21 Pa / 489.67 R = P / 539.67 R
P = 23.1 Pa
Rounded to two significant figures, the pressure is 23 Pa.
Answer:
32.38 square m
Step-by-step explanation:
Diameter of semicircle = 5 m
Hence, radius = 5/2 = 2.5 m
Area of figure = Area of rectangle - 2 times area of one semicircle
