A band will sell CDs of their music at their concert for $5.00 each. The band ordered 300 CDs at a cost of $1.25 each. Which inequality represents the number of CDs, n, the band needs to sell to make a profit of at least $500?
1. x is greater to or equal to 99
2. x is greater to or equal to 100
3. x is greater to or equal to 133
4. or x is greater to or equal to 134
Given:
Selling price of each CD = $5.00
Cost price of each CD = $1.25
Number of CDs ordered = 300
Profit must be at least $500.
To find:
The number of CDs needs to sell.
Solution:
Let n be the number of CDs needs to sell.
Selling price of each CD = $5.00
Selling price of x CDs = $5n
Cost price of each CD = $1.25
Cost price of 300 CDs = 300×$1.25
= $375
We know that,
[tex]Profit=S.P.-C.P.[/tex]
[tex]Profit=5n-375[/tex]
Profit must be at least $500. it means profit must be greater than or equal to $500.
[tex]5n-375\geq 500[/tex]
[tex]5n\geq 500+375[/tex]
[tex]n\geq \dfrac{875}{5}[/tex]
[tex]n\geq 175[/tex]
All options are incorrect. The required inequality is n is greater than or equal to 175.

Answer:
x = 10[tex]\sqrt{2}[/tex]
Step-by-step explanation:
this is a 45-45-90° Δ and the leg to hypotenuse ratio is always 1 : [tex]\sqrt{2}[/tex]
so we can set up a proportion:
20 / [tex]\sqrt{2}[/tex] = x / 1
cross-multiply:
[tex]\sqrt{2}[/tex]x = 20
x = 20 / [tex]\sqrt{2}[/tex], which simplifies to 10[tex]\sqrt{2}[/tex] if you rationalize the denominator

Lauri is picking out material for her new quilt. At the fabric store, there are 1919 solids, 99 striped prints, and 1212 floral prints that she can choose from. If she needs 33 solids, 33 floral prints, and 33 striped fabrics for her quilt, how many different ways can she choose the materials
Answer:
1,79,07,120 ways
Step-by-step explanation:
Ways in which 3 solids can be chosen from 19 solids = 19 c 3
33 striped prints can be chosen from 99 striped prints in 9 c 3 ways
33 floral prints can be chosen from 121 floral prints in 12 c 33 ways
So, total ways = (19 c 3) (9 c 3) (12 c 3)
(969) (84) (220)

What are the truck ID’s of trucks that have carried small shipments. Small shipments are defined as those that weigh less than 800 pounds? (HInt: Avoid duplcates.)
Table for the question is attached in the picture below :
Answer:
SELECT distinct(TRUCK_ID), WEIGHT from SHIPMENT where WEIGHT < 800 ;
Step-by-step explanation:
The Structured query language (SQL) defined above, returns only the TRUCK_ID and Weight column from the shipment table as they are the only two columns listed after the select keyword. The condition is added using the WHERE keyword on the weight table, this filters the result returned to include only rows where the weight value is less than 800. The distinct keyword used alongside the TRUCK_ID column ensures that a certian TRUCK_ID value isn't returned more than once (Hence, it is used to avoid duplicates).

what is 7/8 x 4/7 in simplest form?
The expression (7/8) x (4/7) simplified to its simplest form is 1/2.
To simplify the expression (7/8) x (4/7), you can multiply the numerators together and the denominators together, and then simplify the resulting fraction if possible.
(7/8) x (4/7)
= (7 x 4) / (8 x 7)
= 28 / 56
To simplify this fraction, we can divide both the numerator and the denominator by their greatest common divisor (GCD), which is 28:
28 / 56
= (28 ÷ 28) / (56 ÷ 28)
= 1 / 2
Therefore, (7/8) x (4/7) simplified to its simplest form is 1/2.

How much does 2.5 L of oil cost if 2,000 mL costs $5.00?
Show work
Answer:
$6.25
Step-by-step explanation:
2000ml = 2 litres
2.5L - 2L = 500ml
So now we know that without the 500ml, it is 5 dollars.
Find out how much 500 ml cost.
2000ml = 5.00
1ml = 5.00 ÷ 2000 = 0.0025
500ml = 0.0025 x 500 = 1.25
2L + 500 ml = 2.5L (which 2.5L costs 6.25)
A suitcase is 27 inches long and
24 inches wide. What is the
diagonal length of the suitcase?
Answer:
The diagonal is 30 inches
step-by-step explanation:
The diagonal is 30 inches
Step-by-step explanation:
Assuming a rectangular suitcase (with right angles), we can use the Pythagorean theorem to solve this
a² + b² = c²
so we plug our two values to find the diagonal (hypotenuse)
24² + 18² = c²
576 + 324 = c²
900 = c²
c = √900
c = 30
The diagonal is 30 inches
