48√2 is the right answer.ou go to the store and buy jeans for $40, a shirt for $20, and a jacket for $60. You have a coupon for 35% off. What is the sale price?
Answer:
SAME AS THIS
Explanation:
County A: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!
$75 * 0.0725 = $5.4375
Add the original price and the sales tax.
$75 + $5.4375 = $80.4375
County B: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!
$70 * 0.08 = $5.6
Add the original price and the sales tax.
$70 + $5.6 = $75.6
Then take the difference.
80.4375 – 75.6 = 4.8375
Round to the nearest hundredth: $4.84
Answer:
the sale price would be $78
Step-by-step explanation:
add up all the prices to get 120
35% taken off of 120 is 78
#1: Solve the inequality below.
-3x + 5 < -19
Explanation: Just like any of your two-step equations,
in this inequality, start by isolating the x term which in this
case is -3x by subtracting 5 from both sides.
That leaves you with -3x < -24.
To get x by itself, divide both sides by -3 but watch out.
When you multiply or divide both sides of an inequality by a
negative number, you must switch the direction of the inequality sign.
So we have x < 8 and put your final answer in
set notation and it look like this → {x: x < 8}.

Step-by-step explanation:
Classify the triangles as acute obtuse or right
Answer:
Acute
Obtuse
Right
Acute
Step-by-step explanation:
To see if a triangle is acute, right, or obtuse, you use something similar to the pythagorean theorem:
Let a and b be the shorter sides, c be the longest side.
If a^2+b^2 > c^2, then the triangle is acute.
If a^2+b^2 = c^2, then the triangle is right.
If a^2+b^2 < c^2, then the triangle is obtuse.

jenny has £20 to spend she also wants to but some plates, which are £1.57 each.
what is the greatest number of plates jenny she can buy
Answer:
5
Step-by-step explanation:
1.24 times 3 = 3.72
.95 (the value of pence to a pound in decimal form) = 2.85
6.18 for the teapot
2.72+2.85+6.18=11.75
She now has £8.25 left (20-11.75).
8.25/1.57=the amount of plates she can buy: 5.25477707006, so 5 with some money left

~AH1807D'Angelo bought two shirts at a special sale. He paid the full price of $19.99 for one shirt and got a second shirt of the same price for half off. If the sales tax rate is 8.5%, how much sales tax did D'Angelo pay for the two shirts?
Answer: $2.55
Step-by-step explanation:
He bought the second shirt for half off the first shirt's price. He therefore bought it at:
= 19.99/2
= $10.00
Total paid for both shirts is therefore:
= 19.99 + 10
= $29.99
Sales tax is 8.5% so he paid:
= 29.99 * 8.5%
= 2.54915
= $2.55

Answer:
Area of gray region = [tex]8x^2+8x-7[/tex]
Step-by-step explanation:
The area covered by the furniture can be subtracted from the total area of the room to calculate the area of the gray region.
Total area of the room: [tex]13x^2+7x-2[/tex]
Area taken up by furniture: [tex]5x^2-x+5[/tex]
Area of gray region = total area of the room - area taken up by furniture
Area of gray region = [tex]13x^2+7x-2-(5x^2-x+5)[/tex]
Remember to distribute the negative sign:
Area of gray region = [tex]13x^2+7x-2-5x^2+x-5[/tex]
Combine like terms:
Area of gray region = [tex]8x^2+8x-7[/tex]
Answer:
8x^2+6x+3
Step-by-step explanation:
13x^2+7x-2
- 5x^2- x+3

solve equation
x^2+6x+1=0
give your answer to 2 decimal places
Step-by-step explanation:
x² + 6x + 1 = 0
(x + 3)² - 8 = 0
(x + 3)² = 8
x + 3 = √8 or x + 3 = -√8
x = √8 - 3 or x = -√8 - 3
x = -0.17 or x = -5.83.
The solution of the given quadratic equation x² + 6x + 1 = 0 will be x = -0.17 or x = -5.83.
What is a quadratic equation?An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, and a must not be zero.
For example, 3x² + 6x + 8 = 0 here x has the highest term as 2 and the coefficient of x² is not zero.
As per the given quadratic equation,
x² + 6x + 1 = 0
Make the whole square as
(x + 3)² - 8 = 0
(x + 3)² = 8
x + 3 = √8 or x + 3 = -√8
x = √8 - 3 or x = -√8 - 3
x = -0.17 or x = -5.83.
Hence "The solution of the given quadratic equation x² + 6x + 1 = 0 will be x = -0.17 or x = -5.83".
