Question:
Solve each calculation. Be sure to report your answer with the correct number of significant figures.
5.61000 dg × 1.1010 dg
12.0 m ÷ 3.1415 m
Answer:
1. 
= 
2. 
Step-by-step explanation:
1. 5.61000 dg × 1.1010 dg
We start by representing each digit using scientific notation
Then, Multiply both numbers
First, rearrange
From law of indices, 
;
So, we have
Because 5.61000 is given in 3 significant figures and 1.1010 is given in 4 significant figures, we approximate the result to 4 significant figures
This gives 
Hence, =
2.
12.0 m ÷ 3.1415 m
Using proper notation
12.0 m ÷ 3.1415 m = 
We start by representing 3.1415 using scientific notation
By substitution;
Take 
to the numerator
From law of indices, 
= 10000
Multiply
Divide
Because 12.0 is given in 2 significant figures and 3.1415 is given in 5 significant figures, we approximate the result to 5 significant figures
Answer:
New height = 6
Step-by-step explanation:
The water is going to be the same volume no matter how the tank is orientated.
So you can do this 2 ways.
First way
Find the volume in the tank when the water goes up 24 cm on the height.
V = L*W*h
L = 8
W = 10
H = 24
V = 1920 cm^3
Now do it using the
L = 40
W = 8
h = ?
1920 = L * W * h
1920 = 40 * 8 * h
1920 = 320 * h
h * 320 = 1920
h = 1920/320
h = 6
Or you can do it without finding the 1920
L*W*h = L1 * w1 * h1
8*10*24 = 40 * 8 * h The 8's cancel
10*24 = 40*h Divide both sides by 10
24 = 4h Divide by 4
h = 6
Same as you got before.
Answer:
(7/3, -1). 7/3 is the missing coordinate.
Step-by-step explanation:
Plug in -1 for y. You get:
3x+4=11.
Subtract 4 on each side:
3x=7
Divide each side by 3:
x=7/3
Step-by-step explanation:
first find two numbers u multiply to get 7 and add to get 8: (1×7)=7,(1+7)=8
so in the first bracket u put (x +1) n in the other (x+7)
ans: (x+1)(x+7)
Disjunction would be statements connected with <span>or.
