Solve the area formula for a circle, A = πr2, for r2.
r2 = Aπ
r2 = A – π
Answer:
The solution of r² is r² = [tex]\frac{A}{\pi }[/tex]
Step-by-step explanation:
To solve an equation for one of its variables, do that
Separate the term of this variable on one side and the other terms on the other sidesMake the coefficient of the variable equals1 (if it is not 1)Let us solve the question
∵ The formula of the area of the circle is A = π r²
∵ The subject is r² ⇒ The variable which we need to solve for it
→ By using the 1st step up divide both sides by π to move it from the right
side to the left side
∵ [tex]\frac{A}{\pi }[/tex] = [tex]\frac{\pi r^{2}}{\pi }[/tex]
∴ [tex]\frac{A}{\pi }[/tex] = r²
→ Switch the two sides
∴ r² = [tex]\frac{A}{\pi }[/tex]
Is x=|y| with inputs x=1, x=2, and x=3 a function? Explain
Answer: This is not a function
======================================================
Explanation:
If x = 1, then,
x = |y|
1 = |y|
|y| = 1
y = plus/minus 1
y = 1 or y = -1
The input x = 1 leads to more than one output y = 1 and y = -1 at the same time.
Similar situations occur with x = 2 and x = 3.
This means we do not have a function. A function can only be possible if each input leads to exactly one output.

Answer:
linear
Step-by-step explanation:
linear means that is gains and loses in a straight line. if you were to graph the points on a chart the line will be straight
you can see in set 1 there is one ball
1:1
set 2 is 2 balls
2:2
and set 3 is 3 balls
it increases at a steady rate
therefore it is linear
Does anyone know the answer to these?? Please answer quickly and please don’t joke around .

7.0 x 10^3 + 2.0 x 10^2
Answer:
7200
Step-by-step explanation:
Find the exponents first.
10^3 = 1000
10^2 = 100
So..
7 x 1000 + 2 x 100
Do the multiplication first (BEDMAS - Brackets Exponents Division Multiplication Addition Subtraction).
7000 + 200 = 7200

Divide £320 in the ratio 3:5
Answer:
£120 : £200
Step-by-step explanation:
sum the parts of the ratio, 3 + 5 = 8 parts
Divide the amount by 8 to find the value of one part
£320 ÷ 8 = £40 , then
3 parts = 3 × £40 = £120
5 parts = 5 × £40 = £200
Then £320 in the ratio 3 : 5 is £120 : £200
The division of £320 in the ratio of 3: 5 is £120: £200.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
For example = 2 + 8 + 9
Subtraction = Minus of any two or more numbers with each other called subtraction.
For example = 4 - 8
Division = divide any two numbers or variable called division.
For example 4/8
Multiplication = to multiply any two or more numbers or variables called multiplication.
For example 5 × 7.
Given the amount of £320
Now,
The ratio is 3: 5 so divide 320 by 3 + 5 to find the per unit ratio value.
So,
320/8 = 40
Now,
Multiply by 3 ⇒ 3 × 40 = 120
Multiply by 5 ⇒ 5 × 40 = 200
So ratio 120/200 = £120: £200.
Hence "The division of £320 in the ratio of 3: 5 is £120: £200".

Write the equation of the line that passes through the point (1,4) and is parallel to y=5
Answer:
The equation of the desired line is thus y = 4
Step-by-step explanation:
A line parallel to y = 5 is a horizontal line. The x-coordinate of every point on this line can take on any x-value; the y-coordinate is always 5.
The line that passes through the point (1, 4) has the constant y-coordinate 4, whereas x can take on any value.
The equation of the desired line is thus y = 4; this line passes through (1, 4) as required and is parallel to y = 5.
solve for x. round to the nearest tenth

Noa is making a circular party cake for her sister Léa. He only has the icing left to put on his cake which measures 22cm in radius and which has a height of 11cm. He ran to the store with his remaining $ 5.33 and chose two types of ice cream. The most beautiful but the most expensive will cost him $ 0.20 / 100cm2. Can he buy it or must he take the one that is less expensive?
I WILL GIVE BRAINLIEST
Answer:
C = 2π22 = 138.230076
138.230076 X 11 = 1520.53084
π22^2 = 1520.53084
1520.53084 + 1520.53084 = 3041.06168
3041.0 cm squared
divide by 100 = 30.41
30.41 X 0.2 = 6.082
$6.08
he must take less expensive
A basketball costs $15.00. If the sales tax is 6%, which equation can be used to find the amount of tax?
Answer:
Tax amount = $15.00 x 0.06 =0.9
Total amount of the basketball = $15.00 x 1.06 = $15.90
Answer:
Tax amount = $15.00 x 0.06 =0.9Total amount of the basketball = $15.00 x 1.06 = $15.90
Step-by-step explanation:
Point M is on line segment LN. Given MN = 3x, LN = 4x + 9, and
LM 2x + 7, determine the numerical length of LM.
Answer:
LM = 11 units
Step-by-step explanation:
Given M is on LN , then
LM + MN = LN , substitute values
2x + 7 + 3x = 4x + 9
5x + 7 = 4x + 9 ( subtract 4x from both sides )
x + 7 = 9 ( subtract 7 from both sides )
x = 2
Thus
LM = 2x + 7 = 2(2) + 7 = 4 + 7 = 11

A 6-сm long toy car is 4% of the length of the official scale model of the Batmobile. How long is the official scale model? Show your work (you may use a linear model if you'd like)
Answer:
[tex]150\:\mathrm{cm}[/tex]
Step-by-step explanation:
Let [tex]x[/tex] represent the length of the official scale model. We can set up the following proportion:
[tex]x\cdot 0.04=6[/tex].
Solving, we get:
[tex]x=\frac{6}{0.04}=\fbox{$150\:\mathrm{cm}$}[/tex].

The rational number lies between −67/7 and−78/8
Pls explain and pls don't write bad answer pls
9514 1404 393
Answer:
-135/14
Step-by-step explanation:
There are an infinite number of rational numbers between any pair of numbers you name. These two number have the decimal values ...
-67/7 = -9 4/7 = -9.571428... (repeating)
-78/8 = -9 3/4 = -9.75
So, numbers like -9.6 = -48/5, or -9.7 = -97/10 are rational numbers that lie in the range you specified.
If you like, you can convert these numbers to ones with a common denominator (56).
-67/7 = -536/56
-78/8 = -546/56
These limits suggest several possible rational numbers with 56 as a denominator: -540/56 = -135/14, for example.
