Am I right do radio waves have the lowest frequency?
Answer:
yes you are correct
Step-by-step explanation:
Answer:
YES YOU ARE RIGHTStep-by-step explanation:
Radio wave, wave from the portion of the electromagnetic spectrum at lower frequencies than microwaves. The wavelengths of radio waves range from thousands of metres to 30 cm.

What is 3x+6 if x =2
Answer:
12
Step-by-step explanation:
Answer:
The Answer would be 12
Step-by-step explanation:
This is because, if you replace x with 2, you will be able to compute the following:
y = 3(2) + 6
y = 6 + 6
y = 12

Answer:
13.5 feets
1 inch
Step-by-step explanation:
Given :
Blueprint length (in.) __2 4 6 8 10 12
Actual length (ft) _____3 6 9 12 15 18
From the data:
Blueprint : actual
2 in : 3 feets
Length of wall on blueprint = 9 inches
Actual length of wall :
2 inches = 3feets
9 inches = x
Cross multiply
2x = 27
x = 27 /2
x = 13.5 feets
B.)
For actual width = 1.5 feets
2 inches = 3feets
x = 1.5 feets
3x = 2 * 1.5
3x = 3
x = 3/3
x = 1 inch

The measure of the side length (that is hypotenuse) of the right-angle triangle will be √202 units.
What is a Pythagoras theorem?The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The Pythagoras theorem formula is given as
H² = P² + B²
Let the missing side of this right triangle be х.
Then the measure of the side length (that is hypotenuse) of the right-angle triangle will be
x² = 9² + 11²
x² = 81 + 121
x² = 202
x = √202

What is the center of the circle for this equation:
(x - 6)² + (y + 9)² = 25
Answer:
Step-by-step explanation:
Knowing this information, we can deduce that the center of the circle is at
(
6
,
−
2
)
, and the radius measures 3 units.
x
=

is a vertical line, while the circle will extend equal length in all direction, in function of it's radius. Looking at the centre and adding 3 to the x value, we get the point
(
9
,
−
2
)
. This point doesn't only lie on the circle; it also lies on the line
x
=
9
. Furthermore, this is the furthest possible distance from the center, so the line will only pass through this one point. Therefore, we can state that the line x = 9 is tangent to

Does anyone know the answer to -8=16x + 9
Answer:
x = -17/16
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtraction Property of EqualityStep-by-step explanation:
Step 1: Define
-8 = 16x + 9
Step 2: Solve for x
[Subtraction Property of Equality] Subtract 9 on both sides: -17 = 16x[Division Property of Equality] Divide 16 on both sides: -17/16 = xRearrange/Rewrite: x = -17/16Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -8 = 16(-17/16) + 9Multiply: -8 = -17 + 9Add: -8 = -8Here we see that -8 does indeed equal -8.
∴ x = -17/16 is the solution to the equation.
There are 3 seventh- grade boys,4 seventh-grade girls, 5 eighth grade boys, and 8 eight grade girls that have parts in the school play. One cast member will have the responsibility of introducing the play. That cast member will be chosen randomly. What is the probability that the student introducing the play will be a boy?
Answer:
40%
Step-by-step explanation: 3 + 5 = 8 boys total 4 + 8 = 12 girls total 8 + 12 = 20 kids total. To find out the probability of randomly choosing a boy you have to do the number of boys over the total amount of kids (8/20) which will equal 40%.

. Liliana is renting a beach house for a family vacation. The house charges a $75 cleaning fee plus $95 per night. If Liliana wants to spend a maximum of $645 on the rental, which inequality represents “n”, the number of nights can she afford to rent the beach house?
Answer:
6 nights
Step-by-step explanation:
Set up your equation:
645=95n+75
then subtract the cleaning fee from the total to remove it from both sides
570=95n
then divid the remaining budget by the $95 per night charge
570/95= n =6
Meaning that she can afford 6 nights in the beach house at that price
