Aiko is selling books for $12 each. She wants to make more than $180 in book sales. The inequality 12b > 180 can be used to determine the number of books, b, she must sell in order to meet her goal. Which number line best represents the solution to the inequality?For which equation is x=5 a solution?
Answers
b > 15
The third number line shows the inequality.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
Aiko is selling books for $12 each. She wants to make more than $180 in book sales.
and, the inequality 12b > 180 can be used to determine the number of books, b.
Now, solving the inequality
12b > 180
b > 180/12
b > 15
Hence, the third number line shows the inequality.

A 7.12 µC charge is moving at one half the speed of light perpendicular to a magnetic field of 4.02 mT. How large is the force on the charge?
A.) 4.29 N
B.) 32.90 x 10^(1) N
C.) 4.29 x 10^(12) N
D.) 1.00 x 10^(16) N
Answers
Answer:
The correct option is A: 4.29 N.
Step-by-step explanation:
The magnetic force is given by:
[tex] F = qv\times B = qvBsin(\theta) [/tex]
Where:
q: is the charge = 7.12x10⁻⁶ C
v: is the speed = c/2 = 1.5x10⁸ m/s
B: is the magnetic field = 4.02x10⁻³ T
θ: is the angle = 90° (the speed is perpendicular to the magnetic field)
Hence, the force on the charge is:
[tex]F = qvBsin(90) = 7.12 \cdot 10^{-6} C*1.5 \cdot 10^{8} m/s*4.02 \cdot 10^{-3} T = 4.29 N[/tex]
Therefore, the correct option is A: 4.29 N.
I hope it helps you!

What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
From the equation, the y-intercept is 10. Then the equation is given as,
y = mx + 10
From the graph, the line is passing through (2, 8). Then the slope is given as,
8 = m(2) + 10
8 = 2m + 10
- 2 = 2m
m = - 1
The equation for the line shown in the graph will be y = - x + 10. Then the correct option is D.

* A Frog sits on a number line at point −10. It is allowed to make up to 4 jumps. First, it can make a jump of 8 units in either direction, or it can skip this jump. Then, it can make a jump 4 units long or skip this jump. Then, it can make a jump 2 units long, or skip this jump. And, finally, it can make a one-unit jump or skip it. Where can it be at the end? Answer: The possible numbers where frog could be are from
Answers
Answer and explanation:
Assuming the frog jumps from -10 for all jumps, if the frog decides to make all 4 jumps then :
8 units jump= -2 or -18
4 units jump= -6 or -14
2 units jump= -8 or -12
1 unit jump = -9 or -11
If the frog decides to make one jump then skip the others then:
Either it makes 8 units jump= -2 or -18
Or 4 units jump= -6 or -14
Or 2 units jump= -8 or -12
Or 1 unit jump = -9 or -11
If it decides to make 2 jumps and skip the others then:
Either it makes 8 units jump= -2 or -18
and 4 units jump= -6 or -14
Or 2 units jump= -8 or -12
and 1 unit jump = -9 or -11
Or any other mix of units of jump twice
If it decides to make 3 jumps and skip the others then:
Either it makes 8 units jump= -2 or -18
and 4 units jump= -6 or -14
and 2 units jump= -8 or -12
Or 1 unit jump = -9 or -11
and 4 units jump= -6 or -14
and 2 units jump= -8 or -12
Or any other mix of 3 jumps
If it decides to make no jump at all then the frog would remain at -10
