The value of the inequality is x ≤ 20/3
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
3x + 10 ≤ 30 be equation (1)
On simplifying , we get
Subtracting 10 on both sides , we get
3x ≤ ( 30 - 10 )
3x ≤ 20
Divide by 3 on both sides , we get
x ≤ 20/3
x ≤ 6.333
Therefore , the value of x is less than or equal to ( 20/3 )
Hence , the inequality is x ≤ 20/3

Solve the right triangle.
Answer:
UW=[tex]2\sqrt{66}[/tex] (already solved for you)
UV=[tex]2\sqrt{33}[/tex]
m∠V=45°
Step-by-step explanation:
You're solving for sine because opp/hyp
sin(45°)*[tex]2\sqrt{66}[/tex]=UV
UV=[tex]2\sqrt{33}[/tex]
2) Now you need to solve for an inverse, and since you know UV, you can use inverse cosine (cos^-1) to find your answer

What is the value of c?
the answer is c=8
hope that helps lolol
Answer: c=8
Step-by-step explanation: All three angles in a triangle add up to 180 degrees so 9c+66+42=180. First add 66 and 42 which is 108, so now you have 9c+108=180. Then subtract 108 from both sides to get 9c=72. Finally, divide each side by 9 to isolate c and you get c=8

Fact :: Reason
∠DCE = 90° :: sin ∠EDC = sin 30° = 1/2 = 8/16 = CE/DE
∠ACB = 90° :: ∠DCE and ∠ACB are vertical angles
∠ABC = 60° :: 180 - ∠CAB - ∠ACB = 60°
∠CED = 60° :: 180 - ∠EDC - ∠DCE = 60°
△CDE ⁓ △ABC :: Same angles (AAA)
2)
Let's solve for AB
sin 30° = 1/2
sin 30° = BC/AB = 15/AB
1/2 = 15/AB ⇒ AB = 30
AB = 30 in
Let's solve for AC (using another way)
AC/12 = 15/8
AC = 12 * 15 / 8 = 22.5
AC = 22.5 in

The population of a city has been increasing 3.6% each year. The population in 2005 was 80,000.
You can invest $200 at 8% for 3 years. Find the simple interest.
Answer:
$48
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 8%/100 = 0.08 per year,
then, solving our equation
I = 200 × 0.08 × 3 = 48
I = $ 48.00
The simple interest accumulated
on a principal of $ 200.00
at a rate of 8% per year
for 3 years is $ 48.00.

Answer:
(a)Yellow=10
Green=38
Relative Frequency of Blue =0.32
Relative Frequency of Red =0.2
Relative Frequency of Green =0.38
(b)50 Red balls
Step-by-step explanation:
In 100 trials, the following were recorded.
Frequency of Blue Balls = 32
Frequency of Red Balls = 20
Relative Frequency of Yellow Balls =0.1
Now, Relative Frequency =Number of Outcome of an Event ÷ Total Number of Trials in the Experiment
Total Number of Trials =100
Therefore:
Therefore, Number of Outcomes of Green balls=100-(32+20+10)
=100-62
Number of Outcomes of Green balls=38
(b)If the Number of Trials is Increased to 250
Expected Outcome of Red Balls =Relative Frequency of Red Balls X 250
She should expect 50 red balls.
The sales tax on a $750 computer at J&M Computers is $48.75. What is the sales tax rate?
Answer:
Step-by-step explanation:
So 750 and 48.75
so tax is a percent of the whole or 750
750=100%
48.75=x%
750/100=48.75/x
solve for x
multiply both sides by x
750x/100=48.75
multiply both sides by 100
750x=4875
divide both sides by 750
x=6.5
the asnwe ris 6.5%

Ben earns $10 per hour and $6 for each delivery he makes. He wants to earn more than $155 in an 8-hour workday. What is the least number of deliveries he must make to reach his goal? a) Write an inequality to model the situation. Use d to represent the number of deliveries
Answer:
the number of deliveries would be 13
And, the equation is d ≥ 12.50
Step-by-step explanation:
The inequality function is given below:
Let us assume the d be the number of deliveries
10 × 8 + 6 × d ≥ 155
80 + 6d ≥ 155
6d ≥ 155 - 80
6d ≥ 75
d ≥ 75 ÷ 6
d ≥ 12.50
hence, the number of deliveries would be 13
And, the equation is d ≥ 12.50
