The answer is B, rad 2 over 2
Answer:
A
Step-by-step explanation:
Distinguish exact and uncertain numbers; Correctly represent uncertainty in quantities using significant figures.
a) You are given the rate as 7.4m/min,
The equation would become d = 7.4t where d is the total distance and t would be the total number of minutes.
b) d would be a positive number because the diver is ascending, which means he is moving up towards the surface.
c) To find how long it took the diver, replace d with 41.36 ( how deep the diver was) and solve for t:
41.36 = 7.4t
To solve for t, divide both sides by 7.4:
t = 41.36 / 7.4
t = 5.59 minutes ( 5 minutes and 35 seconds)
The value of x is 8.
Solution:
Given
.
DG = 60, NQ = 48, DN = 15, NV = x + 4
<u>To find the value of x:</u>
<em>Property of similar triangle:</em>
If two triangles are similar then the corresponding angles are congruent and the corresponding sides are in proportion.


Do cross multiplication.


Subtract 240 from both side of the equation.


Divide by 60 on both sides of the equation.


Hence the value of x is 8.
