to make the proportion we make the ratio of the similar sides
For example
4/8 = 12/x
or we can write it as 4/12 = 8/x
or 12/x = 4/8
So last option is correct
Answer:
See below.
Step-by-step explanation:
1 ÷ loga ab + 1 ÷ logb ab
= 1 / (loga ab) + 1 / (loga ab / loga b) { change of log base)
= 1 / (loga ab) + loga b / (loga ab)
= (1 + loga b) / loga ab
= (1 + loga b) / (loga a + loga b) Now loga a = 1 so we have:
((1 + loga b) / (1 + loga b)
= 1.
Answer:
a) There will be approximately a water depth of 7.5 meters after 3h
b) Approximately 2.5 hours have passed when there is 8 m of water in the tank.
Step-by-step explanation:
a) Look for the y-value when the x-value is 3.
b) Look for the x-value when the y-value is 8.
*The y-axis is the depth (m), and the x-axis is the time (h).
Considering the surface area of the rectangular box, it is found that since it is of 502 in² < 1,350 in², she will not need more than 5 cups of paint.
<h3>What is the surface area of a rectangular prism?</h3>
The surface area of a rectangular prism of length l, width w and depth d is given by:
S = 2(lw + ld + wd).
In this problem, we have that the dimensions, in inches, are given by l = 13, w = 8, d = 7. Hence, the <em>surface area</em> in in² is given by:
S = 2(13 x 8 + 13 x 7 + 8 x 7) = 502 in².
Since the surface area of the box is of 502 in² < 1,350 in², she will not need more than 5 cups of paint.
