What is the radius and diameter of the following circle? 4.2cm Please help
Answers
Answer:
The radius is 4.2 and the diameter is always twice the amount of the radius so its 8.4.
Step-by-step explanation:
Answer: R = 4.2cm and D = 8.4cm
Step-by-step explanation: The diameter of a circle is the full line across the circle. The radius of a circle is half of its diameter. The line shown go's halfway through the circle so its the radius. To find the diameter you multiply the radius by 2.
[tex]4.2 * 2 = 8.4[/tex]

Answer: output = -1n + 7 or -n + 7
n can represent any number.
Step-by-step explanation: using the slope-intercept form y = mx + b
y is the output. x is any input. m is the slope. b is the constant.
Calculate the slope: rise ÷ run
You see all the inputs in the chart are going up by 1. This is the run +1
You see all the outputs going down by 1. This is the rise: -1
So the slope, m, is rise / run . -1/1 = -1
To find the constant, use the slope with any pair of inputs and outputs from the chart in place of y and x in the slope-intercept equation.
y = mx + b becomes 6 = -1(1) + b . Solve for b
6 = -1 + b
6 +1 = -1 +1 + b
7 = b
Now set up the equation that answers the question using the calculated values of m and b.
y = -1(x) + 7 . We can answer the question with this equation rewritten a bit:
Output = -1n + 7
or -n + 7 as 1 is usually implied.

Andre drank 1.5 liters of water he brought. If he drank 80% of his entire hike, how much did he drink?
Answers
Answer:
about 1.25
Step-by-step explanation:
Andre drank 1.2 liters out of 1.5 liters of water.
What is a expression? What is a mathematical equation?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.We have Andre who drank 1.5 liters of water he brought. He drank 80% of his entire hike.
Assume that he drank [x] liters of water. Then -
x = 80% of 1.5 liters
x = (80/100) x 1.5
x = 8/10 x 1.5
x = 1.2 liters
Therefore, Andre drank 1.2 liters out of 1.5 liters of water.

24 is 40% of what number? Use the percent equation.
Answers
Divide 24 by 40%
24 / 0.40 = 60
The answer is 60
Using the percentage equation, 24 ( twenty four ) is 40% ( forty percent ) of 60 ( sixty ).
What is Percentage?Percentage is simply number or ratio expressed as a fraction of 100.
The perecent equation is expressed as;
Percentage = ( Part / Whole ) × 100%
Given the data in the question;
Percentage = 40%Part = 24Whole = ?We determine the number, we substitute our given values into the expression above.
Percentage = ( Part / Whole ) × 100%
40% = ( 24 / Whole ) × 100%
40/100 = ( 24 / Whole ) × 100/100
40/100 = 24 / Whole
We cross multiply
40 × Whole = 24 × 100
40 × Whole = 2400
Whole = 2400 / 40
Whole = 60
Therefore, using the percentage equation, 24 ( twenty four ) is 40% ( forty percent ) of 60 ( sixty ).
