Johan is mixing paint he mixes 2 2/3 pints of blue paint and 4 1/6 pints of yellow paint. Which of the following has a ratio of blue paint to yellow paint that is proportional to amounts used in johans paint mixture
Answer:
R = 16:25
Step-by-step explanation:
Given that,
Johan mixes 2 2/3 pints of blue paint and 4 1/6 pints of yellow paint.
We need to find the ratio of blue paint to yellow paint. It can be calculated as follows :
[tex]R=\dfrac{\text{blue paint}}{\text{yellow paint}}\\\\=\dfrac{2\dfrac{2}{3}}{4\dfrac{1}{6}}\\\\=\dfrac{\dfrac{8}{3}}{\dfrac{25}{6}}\\\\=\dfrac{8}{3}\times \dfrac{6}{25}\\\\=\dfrac{16}{25}[/tex]
So, the required ratio is 16:25.

Step-by-step explanation:
the formula for calculating the perimeter of a circle (the circumference C) is:
2π * r
And the area is:
π * r²
r is the radius.
Radius is the half of the diameter. The diameter here is equal to two square. One square is 5 of side.
The diameter is 10 and the radius is 5
C = 2 * 3.14 * 5 = 31.4A = 3.14 * 5² = 3.14 * 25 = 78.5It is the same for the other circle

Step-by-step explanation:
Find the next term of the Taylor series.
f⁽⁰⁾(x) = x^⅓
f⁽¹⁾(x) = ⅓ x^-⅔
f⁽²⁾(x) = -²/₉ x^-⁵/₃
f⁽³⁾(x) = ¹⁰/₂₇ x^-⁸/₃
f⁽⁴⁾(x) = -⁸⁰/₈₁ x^-¹¹/₃
So the fourth term would be:
(-⁸⁰/₈₁ z^-¹¹/₃) (x − 1)⁴ / 4!
For 0.8 ≤ z ≤ 1.2, │f⁽⁴⁾(z)│is a maximum at z = 0.8. Therefore:
│R₃(x)│≤ │(-⁸⁰/₈₁ (0.8)^-¹¹/₃) (0.8 − 1)⁴ / 4!│
│R₃(x)│≤ 0.00014923
Looks like you accidentally wrote an extra zero.

Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
-3(x - 1) = x - 5
Step 2: Solve for x
Distribute -3: -3x + 3 = x - 5Add 3x to both sides: 3 = 4x - 5Add 5 to both sides: 8 = 4xDivide 4 on both sides: 2 = xRewrite: x = 2Step 3: Check
Plug in x to verify it's a solution.
Substitute: -3(2 - 1) = 2 - 5Subtract: -3(1) = -3Multiply: -3 = -3Here we see that -3 does indeed equal -3.
∴ x = 2 is a solution of the equation.

Suppose you like to keep a jar of change on your desk. Currently, the jar contains the following:
13 Pennies 15 Dimes
29 Nickels 26 Quarters
What is the probability that you reach into the jar and randomly grab a dime and then, without replacement, a nickel?
Answer:
The probability is 435/6,806
Step-by-step explanation:
Firstly, the total number of coins in the jar is
13 + 15 + 29 + 26 = 83
The probability of selecting a dime is 15/83
Now we want to grab a nickel
Since we already selected a dime and we did not replace it, the number of total coins in the jar will be 83-1 = 82
So the probability of selecting a nickel this time is
29/82
So the total probability of the event in the described order is;
15/83 * 29/82
= 435/6,806

It costs $480.00 to rent an apartment on the Gold Coast for a weekend. Last year it cost $400.00.
What method below shows how you would calculate the % increase?
Answer:
The third choice.
(480 - 400) / 400 * 100.
Step-by-step explanation:
(480 - 400) / 400 * 100
= 80/400 * 100
= 1/5 * 100
= 20%.
The percentage increase method will be { [ 480 - 400 ] / 400 } x 100. The correct option is C.
What is the percentage?The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
The rent of an apartment is increased from $400 to $480.
The percentage change will be calculated as:-
Subtract $400 from $480 and you will get 80. Then divide 800 by 400 (because 100% = total) and you will get which means 20 %. Her hourly wage increased by 18%.
Percentage change = ( 480 - 400 ) / 400
Percentage change = 80 / 400
Percentage change = 0.2 x 100 = 20 %
Therefore, the percentage increase method will be { [ 480 - 400 ] / 400 } x 100. The correct option is C.

What is the slope of a line that is perpendicular to the line to the line represented by the equation y=1/3x+4
Answer:
C.
Step-by-step explanation:
Perpendicular slope means it's the opposite, meaning the perpendicular slope of 1/3 is -3 because -3 = -3/1. [note: if it's positive it should come out negative and just the opposite if it's a negative (the fraction should also be flipped)]

What is the equation of the line below?
Answer:
[tex] y = -\frac{2}{3}x + 1 [/tex]
Step-by-step explanation:
The equation of the line shown can be expressed in the slope-intercept formula as [tex] y = mx + b [/tex]
Let's find m = slope, and b = y-intercept.
Using two points on the line, (0, 1) and (1½, 0),
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{0 - 1}{\frac{3}{2} - 0} = \frac{-1}{\frac{3}{2}} = - \frac{2}{3} [/tex]
y-intercept, b is where the line intercepts the y-axis = 1.
To create an equation for the line, substitute m = -⅔, b = 1 in [tex] y = mx + b [/tex].
✅The equation would be:
[tex] y = -\frac{2}{3}x + 1 [/tex]
