What is mean by Inequality?A relation by which we can compare two or more mathematical expression is called an inequality.
We have to given that;
The expression of the inequality is,
⇒ m/ 8 < 4
Now, We can simply the expression as;
⇒ m/ 8 < 4
⇒ m/ 8 - 4 < 0
⇒ (m - 32)/8 < 0
⇒ m - 32 < 0
⇒ m < 32
Therefore, The solution of inequality m/8 < 4 is,

Casey is trying to run a certain number of miles by the end of the month if Casey is 60% of the way to achieving our goals and she has already ran 24 miles how many miles is she trying to run by the end of the month
Answer:
40 miles is her goal.
Step-by-step explanation:
The problem says that 24 miles is 60% of her goal for that month.
You cab make a proportion with x being the goal for the whole month.
24/x = 6/10
You cross multiply and get:
6x = 24 x 10
6x = 240
x = 40
40 miles is the answer.
Which of the following is NOT a ratio?
A- (1,2)
B- 1:2
C- 1/2
D- 1 to 2
Answer:
A is not a ratio
Step-by-step explanation:
Answer:
A. - (1,2)
Step-by-step explanation:
We can represent the ratio as a fraction (like in C.), by using the preposition "to" just like in D, and by using a ":" sing just like in number B. So that leaves us with only one option which is A.

A lug nut is used to secure a wheel on a vehicle. Most lug nuts are shaped like regular pentagons or regular hexagons. However, some lug nuts are shaped like regular heptagons (7 sided). What is the measure of each interior angle of a regular heptagon lug nut? Round your answer to the nearest degree
Answer:
[tex]129^{\circ}[/tex]
Step-by-step explanation:
n = Number of sides of a polygon = 7
The interior angles of a polygon is given by
[tex]\theta=\dfrac{(n-2)180^{\circ}}{n}[/tex]
[tex]\Rightarrow \theta=\dfrac{(7-2)\times 180^{\circ}}{7}[/tex]
[tex]\Rightarrow \theta=\dfrac{5\times 180^{\circ}}{7}[/tex]
[tex]\Rightarrow \theta=\dfrac{900^{\circ}}{7}[/tex]
[tex]\Rightarrow \theta=128.57^{\circ}\approx 129^{\circ}[/tex]
Each interior angle of a heptagonal nut is [tex]129^{\circ}[/tex].

Answer:
(b) see below
Step-by-step explanation:
These tables all have x-values that are consecutive integers, including 0.
The equation has an x-coefficient of -1/2, so as x increases by 1, y should decrease by 1/2 from one row of the table to the next. This is only the case for table B.
__
As another check, the y-value for x=0 is the constant in the equation, -1. That is not the case for table C, further evidence that C is incorrect.
A pyrotechnician plans for two fireworks to explode together at the same height in the air. They travel at speeds shown below. Firework B is launched 0.25 s before Firework A. How many seconds after Firework B launches will both fireworks explode? Firework A 240 ft/s Firework B 200 ft/s
Answer: 1.50 seconds
Step-by-step explanation:
Let x = Time taken by Firework A to explode( in seconds ).
Time taken by Firework B = x+ 0.25 seconds
Distance covered = Time × Speed
Distance covered by Firework A = 240 x
Distance covered by Firework B = 200 (x+0.25) = 200x+50
When both at same height , then
240x = 200x+50
⇒ 240x- 200x =50
⇒40x =50
⇒ x = 1.25
Total time = x+ 0.25 = 0.25+ 1.25 = 1.50 seconds
Hence. after Firework B launches it will take 1.50 seconds to launch.
(2,-8) and has a slope of 4
Answer:
The equation of the line is;
y = 4x - 16
Step-by-step explanation:
Here, we want to find the equation of a line that passes through the point (2,-8) and has a slope of 4
To get this equation, we are going to use the point-slope form
Thus, we have it that;
y-y1 = m(x-x1)
y -(-8) = 4(x-2)
y + 8 = 4x - 8
y = 4x -8-8
y = 4x - 16

Answer:
x is 5
ST is 45
Step-by-step explanation:
In the given figure
∵ m is the bisector of the segment SU
→ That means m intersects SU at the midpoint of SU
∵ m ∩ SU at point T
∴ T is the midpoint of SU
→ The midpoint of a segment divides it into two equal parts
∵ The point T divides SU to ST and TU
∴ ST = TU
∵ ST = 9x
∵ TU = 4x + 25
→ Equate them
∴ 9x = 4x + 25
→ Subtract 4x from both sides
∵ 9x - 4x = 4x - 4x + 25
∴ 5x = 25
→ Divide both sides by 5
∴ x = 5
→ Substitute the value of x in ST
∵ ST = 9(5) = 45
∴ ST is 45

Step-by-step explanation:
Given
[tex]\angle J=90^{\circ }[/tex]
HI=88 ft
IJ=62 ft
From the figure, we can write
[tex]\cos I=\frac{IJ}{HI}=\frac{62}{88}=\frac{31}{44}\\I=\cos^{-1} (\frac{31}{44})=45.207^{\circ }\approx 45.21^{\circ }[/tex]
