Let the age of Junior be x,
age of grandpa schmidt = 7x + 9
7x + 9 = 75
7x = 66
x = 66/7
= 9.43 (to three significant figures)
Junior is 9.43 years old.
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
The expanded form of the expression y (0.5 + 6) is
0.5y + 6y
<h3>What is an expression?</h3>
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
y (0.5 + 6)
Expanding we get,
y x 0.5 + 6y
0.5y + 6y
Thus,
The expanded form of the expression y (0.5 + 6) is
0.5y + 6y

Each candle in the set is a different size.
The smallest candle has a radius of 0.5 inches and a height of 3 inches.
The other two candles are scaled versions of the smallest, with scale factors of 2 and 3.
How much wax is needed to create one set of candles?
in cubic inches
Answer
pi 0.5^2 *3 = 0.75pi is the volume of the first candle.
The second volume is 8 * 0.75pi = 6pi.
And the last volume is 27 * 0.75 pi = 20.25 pi So in total we just take the sum and that is 27pi
Answer:
x = 168.75°
Step-by-step explanation:
<u>Angle Measurement Units</u>
To convert from different units for angle measurements, we have to recall that:
180 degrees = π radians
If we are given the angle in degrees, multiply by π/180 to convert it to radians.
If the angle is given in radians, multiply by 180/π to convert to degrees.
We are given the angle:
Multiplying by 180/π:
Simplifying:
x = 168.75°
