Multiply. (3+√2)(4+√2)
The multiplication of the expression ( 3 + √2)( 4 +√2 ) is 14 + 7√2.
Multiplication in elementary algebra is the process of figuring out the outcome of multiplying a number by a number b. The product of a and b is the outcome of multiplication, and each of the integers a and b is referred to as a factor of the product ab.
Consider the expression,
y = ( 3 + √2)( 4 +√2 )
Using the distributive property,
a( b + c ) = ab + ac
y = ( 3 + √2)( 4 +√2 )
y = 3( 4 + √2 ) + √2( 4 + √2 )
y = 3 × 4 + 3 × √2 + √2 × 4 + ( √2 )²
y = 12 + 3√2 + 4√2 + 2
y = 14 + √2( 3 + 4 )
y = 14 + 7√2
The value of the expression ( 3 + √2)( 4 +√2 ) when simplified is 14 + 7√2.

What is 16,504÷55. Using 2 digit divisors write the remainder as a fraction.
16504 divided by 55 equals
300+ 4/55.
First we know about -
Divisor: The number by which the dividend is divided.
Quotient: The result of division.
Remainder: The amount that is left over after division.
Rules for the Division -
1. Take the first digits of the dividend, the same number of digits that the divisor has. If the number taken from the dividend is smaller than the divisor, you need to take the next digit of the dividend.
2. Divide the first number of the dividend (or the two first numbers if the previous step took another digit) by the first digit of the divisor. Write the result of this division in the space of the quotient.
3. Multiply the digit of the quotient by the divisor, write the result beneath the dividend and subtract it. If you cannot, because the dividend is smaller, you will have to choose a smaller number in the quotient until it can subtract.
4. After subtraction, drop the next digit of the dividend and repeat from step 2 until there are no more remaining numbers in the dividend.

A laptop has a listed price of $887.99 before tax. If the sales tax rate is 9.75%, find the total cost of the laptop with sales tax included.
The total cost of the laptop, including the sales tax, is $974.57.
How is the total cost determined?The total cost of the laptop is the addition of the listed price and the sales tax (dollars).
The listed price refers to the retailer's (seller's) price before the addition of the sales tax.
After adding the sales tax to the listed price, the total cost is obtained.
Therefore, sales tax, which is a proportional tax, increases the cost of goods and services to consumers.
Data and Calculations:Listed price before tax = $887.99
Sales tax rate = 9.75%
Total cost after tax = $974.57 ($887.99 x 1.0975)
Thus, the total cost of the laptop after factoring in the sales tax is $974.57.

The loudness in decibels dB of a sound is defined as 10 log I/I₀ , where I is the intensity of the sound in watts per square meter (W / m²) . I₀ , the intensity of a barely audible sound, is equal to 10⁻¹²W/m². Town regulations require the loudness of construction work not to exceed 100 dB . Suppose a construction team is blasting rock for a roadway. One explosion has an intensity of 1.65x10²W/m² . Is this explosion in violation of town regulations?
a. Which physical value do you need to calculate to answer the question?
a) The explosion does violate the town regulation
b) The two physical quantities are the I(intensity of the sound) and
[tex]I_{o}[/tex] (detectable intensity)
The values that we have been given are
L = loudness of the sound = 10 log(I/[tex]I_{o}[/tex])
I = intensity of the sound in watts per square meter = [tex]1.65 * 10^{2} W/m^{2}[/tex]
[tex]I_{o}[/tex] = intensity of barely audible sound = [tex]10^{-12} W/m^{2}[/tex]
Putting the required value in the equation of the loudness we get
a) L = [tex]10 log(\frac{1.65*10^{2} }{10^{-12} } )\\[/tex]
L = 10 * 14.217 dB = 142.17 dB
And according to the town regulation the loudness of the construction work should not exceed 100dB.
Thus the explosion is in violation of the town regulation as it exceeds 100dB.
b) the two physical value we have to calculate are I which is intensity of the sound in watts per square meter and [tex]I_{o}[/tex] which is intensity of barely audible sound. The respective values are
I = intensity of the sound in watts per square meter = [tex]1.65 * 10^{2} W/m^{2}[/tex]
[tex]I_{o}[/tex] = intensity of barely audible sound = [tex]10^{-12} W/m^{2}[/tex]

The vertex F(−2, 4) in the dilated image has coordinates of (−6, 12) option (B) F' is correct.
What is dilation?The transformation dilation is used to resize an item. Dilation is a technique for making items appear larger or smaller. The image created by this transformation is identical to the original shape.
It is given that:
The coordinates are:
Rectangle EFGH has vertices E(−3, 4), F(−2, 4), G(−2, −2), and H(−3, −2).
After applying dilation with a scale factor of 3:
E(−3, 4) → E'(-3x3, 4x3) = E'(-9, 12)
Similarly,
F(−2, 4) → F'(-6, 12)
G(−2, −2) → G'(-6, -6)

Given that there are 6 circles and 3 squares, the simplest ratio of squares to circles is 1 : 2 or 1 to 2 or 1/2.
Ratio is the relationship between two quantities, normally expressed as the quotient of one divided by the other.
It can be expressed in different ways:
1) Use the ":" to separate the values : a : b
2) Use the word "to" : a to b
3) Write it in fraction: a / b
If there are 6 circles and 3 squares. then the ratio of squares to circles can be written as:
3 : 6 or 3 to 6 or 3/6
