After the subtraction, the simplified form of the mixed number is 33/4

Mixed numbers

Mixed fraction means a fraction represented with its quotient and remainder.

Given,

Here we have the mixed numbers 12 5/12 - 4 1/6

Now, we have to perform the subtraction in it and then we have to simplifies it.

Firs we have to convert the mixed numbers into normal fraction, for that we have to do the following:

12 5/12 = (12 x 12) + 5/12

=> (144 + 5)/12

=> 149/12

Similarly, when we simplifies the second one, then we get,

=> 4 1/6 = (6 x 4) + 1/6

=> (24 + 1) / 6

=> 25/6

Here the fractions have unlike denominators.

So, first we have to find the Least Common Denominator and rewrite the fractions with the common denominator.

Therefore, the LCD(149/12, 25/6) = 12

Now, we have to multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD.

=> 149/12 - 50/12

The two fractions now have like denominators so you can subtract the numerators.

Then:

=> 99/12

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 99 and 12 using GCF(99,12) = 3

So, the simplified form of the fraction is

=> 33/4

The measure of angle B is 78°.

∠A = (2x - 9)°

∠B = (2x + 4)°

∠C = x°

In triangle ABC,

      ∠A + ∠B + ∠C = 180°

2x - 9 + 2x + 4 + x = 180

                   5x - 5 = 180

                        5x = 180 + 5

                        5x = 185

                          x = 185/5

                          x = 37

∠B = 2x + 4

Answer: y = 4

Step-by-step explanation:

First, we have to look at the triangle and understand which sides match each other. The side measure of EF matches the side of KH. Since we know these are congruent sides, we can set them equal to each other in an equation. So,

7y - 11 = 17.00

Now we add 11 to both sides, isolating the variable.

7y = 28.00

Now, we divide by 7 on both sides.

7y/7 = 28/7

y = 4

£5,900 in taxes

Step-by-step explanation:

How much Income Tax would be paid by someone earning £41,000 in a tax year when the basic rate of Income Tax is 20% and the annual tax-free personal allowance is £11,500?

41,000 - 11,500 = 29,500 taxable

The required equation is y = 14.85x + 110.25.

The slope-intercept form of a line is y = mx +c where m is the slope of the line and c is the y-intercept.

Given that, Jake collects $311.95 after receiving 21 texts.

Therefore, he collected $311.95/21 per text.

$311.95/21 = $14.85

The collection balance was $422.20, therefore, Jake already has $422.20-$311.95 = $110.25.

Let Jake receives x texts, then he will get $14.85x, and Jake already has $110.25, therefore, the total collection after receiving x texts is:

y = 14.85x + 110.25

Hence, The required equation is y = 14.85x + 110.25.

The equation that represents the proportional relationship is y=14x. The correct option is D.

Given the table which shows a proportional relationship X=1,2,3 and Y=14,28,42.

We want to find an equation that represents the proportional relationship.

We will find the proportional relationship by dividing Y with X.

When X=1 and Y=14 then proportional relationship is

Y/X=14/1

Multiply both sides by X, we get

(Y/X)X=14X

Y=14X.....(1)

When X=2 and Y=28 then proportional relationship is

Y/X=28/2

Y/X=14

Y=14X.....(2)

When X=3 and Y=42 then proportional relationship is

Y/X=42/3

Y/X=14

Y=14X......(3)

From equation (1),(2) and (3) we get that the proportional relationship is Y=14X.

Hence, an equation that represents the proportional relationship when the table shows a proportional relationship is Y=14X.

Answer:  [tex]h = \frac{3}{4}y[/tex] is the cone's height.

==================================================

Work Shown:

Let's set up each volume equation.

[tex]\text{VL} = \text{volume of cylinder}\\\\\text{VL} = \pi*r^2*h\\\\\text{VL} = \pi*x^2*y\\\\[/tex]

[tex]\text{VC} = \text{volume of cone}\\\\\text{VC} = \frac{1}{3}*\pi*r^2*h\\\\\text{VC} = \frac{1}{3}*\pi*(2x)^2*h\\\\\text{VC} = \frac{4}{3}\pi x^2*h\\\\[/tex]

Then we're told that VL and VC are the same value. Let's equate the right hand sides and solve for h.

[tex]\text{VL} = \text{VC}\\\\\pi x^2y = \frac{4}{3}\pi x^2 h\\\\x^2y = \frac{4}{3}x^2 h\\\\3x^2y = 4x^2 h\\\\h = \frac{3x^2y}{4x^2}\\\\h = \frac{3y}{4}\\\\h = \frac{3}{4}y\\\\[/tex]

Answer:

3y

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{4 cm}\underline{Volume of a cylinder}\\\\$V=\pi r^2 h$\\\\where:\\ \phantom{ww}$\bullet$ $(r)$ is the radius. \\ \phantom{ww}$\bullet$ $h$ is the height.\\\end{minipage}}[/tex]   [tex]\boxed{\begin{minipage}{4 cm}\underline{Volume of a cone}\\\\$V=\dfrac{1}{3} \pi r^2 h$\\\\where:\\ \phantom{ww}$\bullet$ $(r)$ is the radius. \\ \phantom{ww}$\bullet$ $h$ is the height.\\\end{minipage}}[/tex]

Given dimensions of the cylinder:

Therefore, the equation for the volume of the cylinder is:

[tex]\implies V_{\sf cylinder}=\pi x^2y[/tex]

Given dimensions of the cone:

Therefore, the equation for the volume of the cone is:

[tex]\implies V_{\sf cone}=\dfrac{1}{3} \pi x^2 h[/tex]

As the cylinder and the cone have the same volume, substitute the equation for the volume of the cylinder into the equation for the volume of the cone an solve for h:

[tex]\begin{aligned}V_{\sf cylinder}&=V_{\sf cone}\\\implies \pi x^2 y&=\dfrac{1}{3} \pi x^2 h\\y&=\dfrac{1}{3} h\\3y&=h\\h&=3y\end{aligned}[/tex]

What do you mean by percentage?

A percentage in mathematics is a number or ratio that is expressed as a fraction of 100. The abbreviations "pct.", "pct.", and occasionally "pc" are also used to indicate it, though the percent sign, "%," is most frequently used. A percentage has no dimensions and no standard measurement.

According to data in the given question,

We have given data:

A local little league has a total of 60 players of whom 20% are right-handed.

Let x be the total number of players that are right-handed.

The value of x can be found as follow:

x = 20% of 60

x = (20/100)60

x = 0.2(60)

x = 12

Therefore, the total number of players that are right-handed is 12, if the local little league has a total of 60 players of whom 20% are right-handed.

Step-by-step explanation: Follow PEMDAS (Parentheses, exponent, multi, divi, add, subtract.)

Step-by-step explanation:

since it is a right-angled triangle, the principle of Pythagoras has to be fulfilled :

c² = a² + b²

c being the Hypotenuse (the side opposite of the 90° angle), which is in our case (x + 32).

a and b are the legs.

so

(x + 32)² = x² + (x + 31)²

x² + 64x + 1024 = x² + x² + 62x + 961

2x + 1024 = x² + 961

x² - 2x - 63 = 0

as 63 = 7×9

and -9 + 7 = -2

we can conclude that this quadratic equation is the same as the following factorization :

(x + 7)(x - 9) = 0

we have 2 solutions :

x = -7

x = 9

as x is also the length of a side, the negative solution does not make any sense.

so, x = 9 is our solution.

that means the sides of the triangle are

x = 9

x + 31 = 40

x + 32 = 41

and the perimeter of the triangle is

9 + 40 + 41 = 90
