Answer:
What error did the salesman make?
The salesman made an error when convert 270 square feet to yards.
What should be the actual cost of the carpet?
The actual cost of the carpet is $360
Step-by-step explanation:
From the question, we are told that:Tisha orders a carpet for a room that measures 270 square feet.
This means the room needs 270 square feet of carpet
But from the question, we know that the carpet is sold in square yards
We convert square feet to square yards
For our conversion rates
3 ft = 1 yard
9 ft² = 1 square yards(yd²)
270 ft² = x
Cross Multiply
9 ft² × x = 270ft² × 1 yd²
x yd²= 270ft² × 1 yd²/9 ft²
x = 30 yd²
Hence, 270ft² = 30yd²
Cost of carpet =
1 yd² = $12.00
30 yd² =
Cross Multiply
= 30 × $12.00
= $360.00
The actual cost of the carpet is $360
What error did the salesman make?
The salesman made an error when convert 270 square feet to square yards.
He said 270 square feet = 90 square yards
But he was wrong.
270 square feet = 30 square yards.
What should be the actual cost of the carpet?
The actual cost of the carpet is $360

Jack and Sara went out to lunch. They spent $28.72 on
their meal. Jack and Sara wanted to leave the waitress a
15% tip. What is the final cost?
Tip = $28.72 x 15% = $4.308
=> Final cost = $28.72 + $4.308 = $33.208
Answer:
33.03
Step-by-step explanation:
you multiply 28.72 by 15%or (.15) you will get 4.308, then you add 4.308 and 28.72 and you will get 33.028 then you round it up and get 33.03
Michael is saving to buy a car. He has 1/4 what he needs to buy the car. His savings account has a balance of $1000. How much more does he need to save?
Answer:
3000
Step-by-step explanation:
If you take the amount he already has (1000) and multiply by the reciprocal (4) you'll get $4000, the amount that the car costs. From there subtract the amount he already has (1000) and you get the amount he still needs (3000).

What is the slope of the line that passes through the points (-2, -1) and (2, -3)?
Answer:
[tex]m=\frac{-1}{2}[/tex]
Step-by-step explanation:
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Simply plug in the 2 coordinates into the slope formula to find slope m:
[tex]m=\frac{-3-(-1)}{2-(-2)}[/tex]
[tex]m=\frac{-3+1}{2+2}[/tex]

DESCRIBE how a power with a zero exponent (a^0) and a power with a negative exponent (a^−n) can be simplified.
Answer:
[tex]a^{-n}[/tex] is [tex](\frac{1}{a})^{n}[/tex] OR [tex]\frac{1}{a^{n} }[/tex]
[tex]a^{0}[/tex] = 1, where a ≠ 0
Step-by-step explanation:
To simplify the exponents, you must put it in positive value
Example:
The simplest form of [tex]2^{-3}[/tex] is to change the exponent from negative value to positive value.
You can do that by reciprocal the number, [tex]2^{-3}=(\frac{1}{2})^{3}[/tex]You can write it [tex]\frac{1}{2^{3}}[/tex], because 1 to any power equal 1That means if you want to simplify [tex]a^{-n}[/tex], reciprocal a and change the sign of the power from -n to n
The simplest form of [tex]a^{-n}[/tex] is [tex](\frac{1}{a})^{n}[/tex] OR [tex]\frac{1}{a^{n} }[/tex]
For any number, a (a ≠ 0), 1 × a = a, so, the reason that any number to the zero power is 1 because any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, (1)
Example:
The value of [tex](5)^{0}[/tex] = 1, because it is the product of no numbers, so it is equal to the multiplicative identity (1)
That means [tex]a^{0}[/tex] = 1, where a ≠ 0
Very important note:
[tex](0)^{0}[/tex] is undefined value
10 + 6x = 15 + 9x – 3x
Answer:
No solution
Step-by-step explanation:
Step 1: Write equation
10 + 6x = 15 + 9x - 3x
Step 2: Solve for x
Combine like terms: 10 + 6x = 15 + 6xSubtract 6x on both sides: 10 ≠ 15Here, we see that x would equal no solutions. You can also think of it as parallel lines; they have the same slope but different y-intercepts, so they will never intersect.

Make a table of ordered pairs for the equation.
y=−1/3x+4
Then plot two points to graph the equation.
Let's pose x as 0, 1, 2, and 3, substituting for y to receive the "ordered pairs"
y = - 1/3(0) + 4 = 0 + 4 = 4
y = - 1/3(1) + 4 = - 1/3 + 4 = - 1/7
y = - 1/3(2) + 4 = - 2/3 + 4 = 10/3
y = - 1/3(3) + 4 = - 1 + 4 = 3
Table of ordered pairs:
x | y
0 | 4
1 | - 1/7
2 | 10/3

What values of a and b make this equation true?
(4 + ✓–49) – 2(/(-4)2 + V–324) = a + bi
Answer:
-4 , -29
Step-by-step explanation:
The values of a and b that make the equation true are -28 and -9, respectively
How to determine the true values of a and b?The equation is given as:
(4 + √-49) – 2((-4)² + √–324) = a + bi
Evaluate the exponents
(4 + 7i) – 2(16 + 18i) = a + bi
Expand the bracket
4 + 7i – 32 - 16i = a + bi
Collect like terms
4 – 32 + 7i - 16i = a + bi
Evaluate like terms
-28 -9i = a + bi
By comparison, we have:
a = -28 and b = -9
Hence, the values of a and b that make the equation true are -28 and -9, respectively

Karen is saving money to buy a game . So far he saved $15 , which is three fourths . How much does the game cost ?
Answer:
$25
Step-by-step explanation:
Let X = total cost of game
(3/5) X = $15
Multiply both sides of equation by 5/3
(5/3)(3/5) X = (5/3) $15
X = $25
cost of game is $25
It costs Ruth $12.50 a week to wash and dry her clothes at the laundromat. If a
washer and dryer cost a total of $940, how many weeks will it take for Ruth's laundry
cost to equal the cost of the washer and dryer?
Answer: 75.2 per week
Step-by-step explanation:
A 76 weeks for Ruth's laundry cost to equal the cost of the washer and dryer.
To find out how many weeks it for Ruth's laundry cost to equal the cost of the washer and dryer, to set up an equation.
Let's assume it takes "x" weeks for Ruth's laundry cost to equal the cost of the washer and dryer.
In one week, Ruth's laundry cost is $12.50. Therefore, in "x" weeks, her total laundry cost would be 12.50 × x.
The cost of the washer and dryer is $940.
Now set up the equation:
12.50 × x = 940
To solve for "x," divide both sides of the equation by 12.50:
x = 940 / 12.50
x = 75.2
Therefore, it will take approximately 75.2 weeks for Ruth's laundry cost to equal the cost of the washer and dryer. Since the number of weeks cannot be fractional, round up the answer to the nearest whole number.
