Step-by-step explanation:
1) The area of rectangle is ( 30x²y + 20xy ) cm² and its breadth is 10xy cm .Find its length....
= Solution ,
Length ( L ) = ?
breadth ( b ) = 10xy cm
area ( a ) = ( 30x² + 20xy )
Now ,
area ( a ) = l × b
or, ( 30x²y + 20xy ) = L × 10xy cm
2) Subtract the quotient when 20x⁴y² is divided by 5x³y from the product of 2x and 3y.
= Solution,
The product of 3x and 4y = 6xy
= 6x - 4xy
hope it helped !!!!
Answer:
10 tickets
Step-by-step explanation:
25 + 5x = 35 + 4x
solve for x:
subtract 25 from both sides...
5x = 35 - 25 + 4x
subtract 4x from both sides...
5x - 4x = 10
x = 10, 10 tickets.
Answer:
<u>Population : all the steaks Tessa can cook</u>
<u>Parameter : minimum internal temperature of 160 degrees Fahrenheit</u>
<u>Sample : two random thermometer readings</u>
<u>Statistic : minimum sample reading of 165 degrees Fahrenheit</u>
Step-by-step explanation:
Let's recall the definitions of these statistical concepts and match it with the information that were provided to us:
- Populations can be the complete set of all similar items that exist, in our case, all the steaks that Tessa can cook.
- Parameter is is a value that describes a characteristic of an entire population, such as the minimum temperature of the steaks Tessa is cooking in Fahrenheit degrees.
- Sample is a subset of the population, in our case, the two random readings of the thermometer Tessa did.
- Statistic is a characteristic of a sample, for our problem, it's the minimum reading of 165 degrees Fahrenheit.
Answer:
A = amount left
so i think the answer could be:
A=9-3x
Answer: 104$
Explanation:
She is paid 7$ for each of the first 7 demo
And she is paid 11$ for each demo over the 7 demo
But she did 12 demo, which mean the first 7 demo she got paid 7$ each and for the last 5 demo she got paid 11$ for each demo.
(7 • 7) + (11 • 5)
= 49 + 55
= 104$
