Answer:
The value of b = -2.7
Step-by-step explanation:
Given
As the equation is given by
[tex]-5=b-2.3[/tex]
To determine
Solve the equation for b
Given the equation
[tex]-5=b-2.3[/tex]
switch the sides
[tex]b-2.3=-5[/tex]
Add 2.3 to both sides
[tex]b-2.3+2.3=-5+2.3[/tex]
Simplify
[tex]b=-2.7[/tex]
Therefore, the value of b = -2.7
Answer:
b = -2.7

PLEASE HELP!!!!! Find the magnitude and direction of the vector <2,7>. Round angles to the nearest degree and other values to the nearest tenth.
7.3; 73°
7.3; 74°
7.4; 73°
7.4; 74
Answer:
It's 7.3; 74!
Step-by-step explanation:
This was a lucky guess for me on my homework and it was correct sooooo.... I don't really have an explanation...
Definition: For vector [tex]v=<a,b>[/tex], the magnitude is defined as [tex]|v|=\sqrt{a^{2} +b^{2} }[/tex], and the direction of the vector is defined as [tex]tan^{-1}(\frac{b}{a} )[/tex].
Here, [tex]v=<2,7>[/tex].
Then, magnitude is:
[tex]|v|=\sqrt{2^{2}+7^{2} } \\|v|=\sqrt{4+49 } \\|v|=\sqrt{53} \\|v|=7.3[/tex]
The direction is:
[tex]tan^{-1}(\frac{7}{2} )=74^{o}[/tex].
So, the correct option is 7.3,74°.

Geometry help please and thank you
Answer:
125°
Step-by-step explanation:
By exterior angle theorem:
(3x - 70)° = 60° + x°
(3x - 70)° - x°= 60°
(3x - 70 - x)° = 60°
(2x - 70)° = 60°
2x - 70 = 60
2x = 60 + 70
2x = 130
x = 130/2
x = 65
(3x - 70)° = (3*65 - 70)° = (195 - 70)° = 125°

Answer this question for 20 points.
Answer:
I believe the answer would be the option that says: "An elephant walks with a speed of 15 steps a minute. How long was the elephant walking if she walked without stopping for 480 steps?"
Answer:
C. An elephant walks with a speed of 15 steps a minute. How long was the elephant walking if she walked without stopping for 480 steps?
Step-by-step explanation:
C yields the equation of [tex]15x=480[/tex], because 15 stands for steps/minute, 480 for steps, so [tex]x[/tex] must stand for minutes.
For your entertainment:
A gives [tex]x = 480 \cdot 15[/tex].
B gives [tex]x=32-15[/tex].
D gives [tex]x=480+15[/tex].
solve for x 5x + 3 - 2x = 24 (also don't have the answer be a fraction)
Answer:
x=7
Step-by-step explanation:
Let's solve your equation step-by-step.
5x+3−2x=24
Step 1: Simplify both sides of the equation.
5x+3−2x=24
5x+3+−2x=24
(5x+−2x)+(3)=24(Combine Like Terms)
3x+3=24
3x+3=24
Step 2: Subtract 3 from both sides.
3x+3−3=24−3
3x=21
Step 3: Divide both sides by 3.
Answer: x=7
Step-by-step explanation:
Given
5x + 3 - 2x = 24
Subtract both sides by 3
5x + 3 - 3 - 2x = 24 - 3
5x - 2x = 21
Simplify
3x = 21
Divide both sides by 3
3x / 3 = 21 / 3
x=7

The relationship between the intensity of sound((w)/(m^(2)))and the distance from the source of sound is represented by the equation (i)=((k)/(d^(2))).If you sit only one meter away from the stage at a rock concert the intensity of sound is about 0.1(w)/(m^(2)). If vanessa does not want the sound intensity to be more than 0.001(w)/(m^(2)) how close to the stage can she sit?
Answer:
10 m
Step-by-step explanation:
We are given that the relationship between intensity of sound and distance from the source is given by
Intensity (I)=[tex]\frac{k}{d^2}[/tex]
Where I=Intensity
d=Distance of sound from the source
If distance d=1m
Intensity, I=0.1[tex]w/m^2[/tex]
We have to find how close she can to the stage if vanessa does not want the sound intensity to be more than 0.001(w)/(m^(2)).
Using the formula
[tex]0.1=\frac{k}{1}[/tex]
[tex]k=0.1[/tex]
[tex]\frac{0.1}{d^2}\leq 0.001[/tex]
[tex]\frac{0.1}{0.001d^2}\leq 1[/tex]
[tex]\frac{0.1}{0.001}\leq d^2[/tex]
[tex]100\leq d^2[/tex]
[tex]10\leq d[/tex]
[tex]d=10 m[/tex]
Hence, she can sit 10 m away from the stage.
