This is probably in the context of a discussion of significant figures and accuracy.
When we record a measurement of 4.15 cm with two significant figures, that means we believe the exact value is in the range from 4.145 cm to 41.155 cm
Similarly 7.34 really means between 7.335 and 7.345 cm.
The minimum area rectangle is
The maximum area rectangle is
Choice A
It takes 42 minutes for 6 people to paint 7 walls
<em><u>Solution:</u></em>
It takes 54 minutes for 4 people to paint 6 walls
To find: Minutes required for 6 people to paint 7 walls
If 
men can do 
work in 
days working 
hours per day and 
men can do 
work in 
days working 
hours per day, then
M = Number of men
D = Number of days
H = Number of hours per day
W = Amount of work
Here in this sum,
<em><u>54 minutes for 4 people to paint 6 walls</u></em>
<em><u>Minutes required for 6 people to paint 7 walls</u></em>
<em><u>Substituting the values in formula, we get</u></em>
Thus it takes 42 minutes for 6 people to paint 7 walls
Answer:
C. x < 40
Step-by-step explanation:
x/5 - 3 < 5
x/5 -3 + 3 < 5 + 3
x/5 < 8
(5/1) x/5 < 8 (5/1)
x < 40
The relation represented by the arrow diagram is {(-3, 4), (-1, 5), (0, 7), (2, 2), (5, 7)}.
Option: C.
<u>Step-by-step explanation:</u>
A function is a relation in which each input value(domain) results in one output value(range). It is represented diagrammatically using the mapping method.
It shows how each element of domain and range are paired. That is like a flowchart it shows the input values marking its corresponding output value.
In the given diagram,
The values given in the left are domain and values given in the right are range.
Thus, -3 marks to 4, then can be written as (-3,4).
Similarly,
-1 marks 5 = (-1,5).
0 marks 7= (0,7).
2 marks 2= (2,2).
5 marks 7 =(5,7).
⇒ The complete points sequence is {(-3, 4), (-1, 5), (0, 7), (2, 2), (5, 7)}.
Step-by-step explanation:
log2x = 1 - log(x+4)
log2x = log10 - log(x+4)
log2x = log[10/(x+4)]
2x = 10/(x+4)
2x(x+4) = 10
2x² + 8x - 10 = 0
÷2 both sides of equation
x² + 4x - 5 = 0
(x+5)(x-1) = 0
x = -5, 1
x isn't be -5 because logA, A need to be > 0
So, x value is 1
