Answer:
-3< x ≤ 4
Step-by-step explanation:
There is an open circle at -3, so -3 is not included
There is a closed circle at 4, which means 4 is included
The line is between which means x is between
-3 is less than x which is less than or equal to 4
-3< x ≤ 4
This type of graph is called a segment.
To write the inequality, read the segment from left to right.
We would start with the endpoint on the left which is a -3,
our variable x would be in the middle, and we would finish
things off with the endpoint on the right, which is 4.
Since we have an open dot at -3, we use a less than
sign between the -3 and the x and since we have a closed at 4,
we use a less than or equal to sign between the x and 4.
When representing a segment by reading it from left to right,
you will only use less than or less than or equal to between the parts.
So the solution for the inequality is read {x: -3 < x ≤ 4}.

A store owner wants to prepare 100 lb of a candy mix that she will sell for $1.36 per lb. She mixes 20 lb of jelly beans that cost 20 cents per lb with sugar candies. How much does 1 lb of sugar candies cost. I WILL MARK BRAILIEST, PLEASE HELP ME! I don't get it!
Answers
Answer: 1.65
I hope this isn't too late : )
The cost of 1 lb of sugar candies is $1.65.
What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
here, we have,
Explanation
Given to us
weight of candy mix = 100 lb,
weight of jelly beans = 100 lb,
Cost of jelly beans = 20 cent per lb = $0.20 per lb,
Cost of candy mix = $1.36 per lb.
Total cost of candy mix:
Total cost of candy mix = weight of candy mix * Cost of candy mix
= 100 lb * $1.36
Total cost of Jelly beans:
Total cost of Jelly beans = weight of Jelly beans * Cost of Jelly beans
= 20 lb* $0.20
Weight of Sugar candies:
weight of Sugar candies = weight of candy mix - weight of jelly bean
= 80 lb
Total cost of sugar candies:
Total cost of candy mix = Total cost of jelly beans + total cost of sugar candies
100 lb * $1.36 = 20 lb* $0.20+ 80lb*x
solving we get,
x = 1.65
Hence, the cost of 1 lb of sugar candies is $1.65.

Answer:
x = 65
Step-by-step explanation:

An aeroplane flew from Qatar to Bahrain. The distance flown was 135 km. The average speed was 180 km/h. Work out the time taken. Give your answer in minutes
Answers
Given:
The distance flown was 135 km.
The average speed was 180 km/h.
To find:
The time taken by the airplane.
Solution:
We know that,
[tex]Speed=\dfrac{Distance}{Time}[/tex]
[tex]Time=\dfrac{Distance}{Speed}[/tex]
Putting Distance = 135 and Speed = 180, we get
[tex]Time=\dfrac{135}{180}[/tex]
[tex]Time=0.75[/tex]
The time taken by the airplane is 0.75 hours.
We know that,
1 hour = 60 min
0.75 hour = 0.75 × 60 min
0.75 hour = 45 min
Therefore, the time taken by the airplane is 45 min.

Answer:
Step-by-step explanation:
First, we need to find the hypotenuse, so we need to apply the equation from the Pythagorean Theorem
A^2+B^2=C^2.
We know A^2 and B^2, so we need to substitute that into the equation
2^2+4^2=C^2
so now, simplify.
4+16=C^2
20=C^2
Square root of 20 is about 4.5
so 4.5 is the length of the sides of the square.
4.5x4.5=20.25

Find the compound interest on 5000 at 12% interest for 15 years.
if the interest is compounded semi-annually.
Answers
18000
Step-by-step explanation:
5000*12%= 600 600× 30= 18000 15 years semi annually = 30 x
The compound interest on $5,000 at 12% interest for 15 years compounded semi-annually is $22,243.58
To find the compound interest on $5,000 at 12% interest for 15 years compounded semi-annually, we can use the formula:
A = P(1 + r/n)^(n*t)
where:
P = principal amount = $5,000
r = annual interest rate = 12% = 0.12
n = number of times compounded in a year = 2 (compounded semi-annually)
t = time period in years = 15
A = amount after t years
Plugging in the values, we get:
A = 5000(1 + 0.12/2)^(2*15)= $27,243.58
So, the amount after 15 years is $27,243.58. To find the compound interest, we can subtract the principal amount from the amount after 15 years:
Compound interest = A - P
= $27,243.58 - $5,000
= $22,243.58
Therefore, the compound interest on $5,000 at 12% interest for 15 years compounded semi-annually is $22,243.58.
