An entertainment firm offers several DJ choices and light shows that range in price based on the rental time period. The DJ's cost between $219.00 and $369.00 per night and the light shows cost between $159.00 and $309.00 per night. If you are booking both a DJ and a light show, write a compound inequality that represents the possible total amount you would pay, x.

Answers

Answer 1
Answer: 219.00 + 159.00 = 378.00, the lowest cost of DJ & lights 369.00 + 309.00 = 678.00, the highest cost of DJ & lights This means the lowest cost would be $434.00, and the highest cost would be $678.00, which written as our compound inequality: $378.00 ≤ x ≤ $678.00 If we wanted to write it as an interval format, it would look like: [$378.00, $678.00] (We use brackets because it's less/greater than or equal to those amounts.)

Find the real-number root.001O no real rootsO 0.1O 0.1 and 0.1O 0.1 I need help

Answers

for cube roots of a positive number, it could have a real number of a negative number but has to contain 2 negatives if it does and one positive. Eg. (-)*(-)* (+) = +

0.001 can be made by multiplying 3 0.1's (0.1^3)
However, we are finding the root here so my explanation above tells us that a cuberoot of a positive number is never a negative.

So the answer is 0.1
0.1

0.1^3 = 0.1*0.1*0.1 = 0.01*0.1 = 0.001

The largest state in the US is Alaska, covering 663,267 square miles (including water). What is the approximate radius of a sphere with the same surface area as the area of Alaska?

Answers

So we wan't to calculate the radius of a sphere that has the area of Alaska that is A=663.267 square miles. First, lets see what is the formula for the area of the sphere: A= 4*pi*r^2. Here we can solve the equation to get the radius: r^2=A/(4*pi) and the last step is: r= sqrt ( A/(4*pi) ). After we input the numbers we get: r= 224.54 miles.

Answer:

answer is C

Step-by-step explanation:

Select the correct answer. The sum of two numbers is -18. If the first number is 10, which equation represents this situation, and what is the second number? A. The equation that represents this situation is 10 − x = -18. The second number is 28. B. The equation that represents this situation is 10 + x = -18. The second number is -28. C. The equation that represents this situation is x − 10 = -18. The second number is -8. D. The equation that represents this situation is -10 + x = -18. The second number is -8.

Answers

Answer:-28

Step-by-step explanation:

Let A is the second number

the first number is 10.

The total is -18

=> 10 + A =-18 <=> A=-18-10=-28

a snail moves at a speed of 2.394 inches per minute . If the snail keeps moving at this rate, about how many inches will it travel in 7.489

Answers

2.394 inches per minute x 7.489 minutes = 17.928666 inches.

So, about 18 inches.
(2.394in)/(1min) *  (7.489min)/(1) = 17.928666in

Or 17.93in with significant digits.


To break it down, you can set up your information as a fraction (which I did for the first fraction.) Then you want your units to cancel out, so I put the 7.489 minutes on the top of the next fraction and multiplied them. The min canceled out and left me with in, so I know I had the correct answer.
