A ∩ B =  {2, 4}.

Answer:

Melisa's height = 150 cm

Step-by-step explanation:

Initially, we are told there are 4 girls and their average height is 152 cm.

Now, the formula for this average is;

Average height = total sum of heights/number of girls

Thus;

152 = total sum of heights/4

We cross multiply to get;

Total sum of heights = 152 × 4

Total sum of 4 girls height = 608 cm

Now we are told that melissa joins them and the average height of the 5 of them is now 151.6.

Let melissa's height be x.

Thus;

Total height of 5 girls is now; (608 + x)

So, from the formula for average initially;

151.6 = (608 + x)/5

Cross multiply to get;

151.6 × 5 = (608 + x)

758 = 608 + x

Subtract 608 from both sides to get;

758 - 608 = x

x = 150 cm

[tex]\frac{7}{24}[/tex]

Step-by-step explanation:

We can solve like so:

[tex]1-\frac{3}{8}-\frac{1}{3}=mushroomcaps\\\\\frac{24}{24} -\frac{9}{24}-\frac{8}{24} =mushroomcaps\\\\\frac{15}{24}-\frac{8}{24}=mushroomcaps\\\\\frac{7}{24}=mushroomcaps[/tex]

[tex]\frac{7}{24}[/tex] of the barbecued items are mushroom caps.

Answer:

E. [tex]x=\frac{7}{24}[/tex]

Step-by-step explanation:

[tex]\frac{3}{8} + \frac{1}{3} +x = 1\\[/tex]

[tex]\frac{3*3}{8*3} + \frac{1*8}{3*8} +x = 1\\\\\frac{9}{24} + \frac{8}{24} +x = 1\\\\\frac{17}{24} +x=1\\[/tex]

[tex]x=1-\frac{17}{24}= \frac{24}{24}-\frac{17}{24} =\frac{7}{24}\\ x=\frac{7}{24}[/tex]

Answer:

It would require 40 teaspoons

Step-by-step explanation:

Given that;

A cookie recipe requires 3 teaspoons of baking soda for 36 cookies

The amount of teaspoons of baking soda required per cookie is;

r = 3/36 teaspoons per cookie

So, for 480 cookies i would require;

N = r × 480 cookies

Substituting r, we have;

N = 3/36 teaspoons per cookie × 480 cookies

N = 40 teaspoons

It would require 40 teaspoons

44.64 milles

Step-by-step explanation:

Van haver de fer una excursió a una casa rural que està a 72 quilòmetres del seu poble.

El primer dia viatgen 2/3 de camí. Aquest dia, van viatjar:

2/3 * 72 = 48 quilòmetres

En el segon dia viatgen 1/4 de camí. Aquest dia, van viatjar:

Answer: y=-6x+26

Step-by-step explanation: We can find the slope of a line that is perpendicular to another line by taking the negated reciprocal of the slope of the original line. So our slope for the perpendicular line is: -6. Now we can put this in a equation to find the y-intercept. So the equation is y=-6x+26

C. 2/15

Step-by-step explanation:

So since 5 eggs weigh 2/3 of a pound, you have to divide 2/3 by 5 to find how much each egg weighs.

2/3/5 is the same as multiplying 2/3 by 1/5.

This gives you 2/15.

Answer:

108πin³

Step-by-step explanation:

The volume of a cone = ⅓ of the volume of a cylinder

Thus, volume of cylinder = 2πr²h

Where, r = radius, h = height of cylinder.

Volume of cone = ⅓×πr²h

So therefore, the volume of a cone given = ⅓ of the volume of a cylinder with the same height and and base of the cone

Thus,

If Volume of cone = 36πin³ , volume of cylinder would be 3 × 36πin³

Volume of cylinder = 108πin³

Answer:

The ratio APBQ : APBC is 4:21, AAQP : AABC is 3:28

Step-by-step explanation:

Data provided in the question

AP : PC = 1 : 3

So let us assume AP = x and PC = 3x.

And, If AQ : QB = 3 : 4

So, let us assume AQ = 3y and QB = 4y.

Now we have to find the area of ΔAQP and ΔABC

[tex]A_{AQP}=\dfrac{1}{2}\cdot AP\cdot AQ\cdot \sin\angle A=\dfrac{1}{2}\cdot x\cdot 3y\cdot \sin\angle A;[/tex]

[tex]A_{ABC}=\dfrac{1}{2}\cdot AC\cdot AB\cdot \sin\angle A=\dfrac{1}{2}\cdot (x+3x)\cdot (3y+4y)\cdot \sin\angle A=\dfrac{1}{2}\cdot 4x\cdot 7y\cdot \sin\angleA[/tex]

Therefore

[tex]\dfrac{A_{APQ}}{A_{ABC}}=\dfrac{\frac{1}{2}\cdot x\cdot 3y\cdot \sin\angle A}{\frac{1}{2}\cdot 4x\cdot 7y\cdot \sin\angleA}=\dfrac{3}{28}.[/tex]

Now

[tex]\dfrac{A_{APQ}}{A_{ABP}}=\dfrac{\frac{1}{2}\cdot x\cdot 3y\cdot \sin\angle A}{\frac{1}{2}\cdot x\cdot (3y+4y)\cdot \sin\angle A}=\dfrac{3}{7}.[/tex]

Now after solving these two ratios we can find

[tex]A_{ABP}=\dfrac{7}{3}A_{APQ}\Rightarrow A_{PBQ}=A_{APB}-A_{APQ}=\dfrac{7}{3}A_{APQ}-A_{APQ}=\dfrac{4}{3}A_{APQ}[/tex]

[tex]A_{ABC}=\dfrac{28}{3}A_{APQ}\Rightarrow A_{PBC}=A_{ABC}-A_{APB}=\dfrac{28}{3}A_{APQ}-\dfrac{7}{3}A_{APQ}=7A_{APQ}.[/tex]

Therefore

[tex]\dfrac{A_{PBQ}}{A_{PBC}}=\dfrac{\frac{4}{3}A_{APQ}}{7A_{APQ}}=\dfrac{4}{21}.[/tex]

Hence, we applied the above equation so that we can get to know the ratios

Answer:

[tex]\frac{y-x}{x+y}[/tex]

Step-by-step explanation:

We are given that fraction

[tex]\frac{\frac{1}{x}-\frac{1}{y}}{\frac{1}{x}+\frac{1}{y}}[/tex]

We have to find the expression which is equivalent to given  fraction .

[tex]\frac{1}{x}-\frac{1}{y}=\frac{y-x}{xy}[/tex]

[tex]\frac{1}{x}+\frac{1}{y}=\frac{x+y}{xy}[/tex]

Substitute the values  then, we get

[tex]\frac{\frac{y-x}{xy}}{\frac{y+x}{xy}}[/tex]

We know that

[tex]\frac{\frac{a}{b}}{\frac{x}{y}}=\frac{a}{b}\times \frac{y}{x}[/tex]

Using the property then, we get

[tex]\frac{y-x}{xy}\times \frac{xy}{x+y}[/tex]

[tex]\frac{y-x}{x+y}[/tex]

This is required expression which is equivalent to given expression.

The equivalent fraction of the given fraction is needed.

The equivalent fraction is [tex]\dfrac{y-x}{y+x}[/tex]

The given fraction is

[tex]\dfrac{\dfrac{1}{x}-\dfrac{1}{y}}{\dfrac{1}{x}+\dfrac{1}{y}}[/tex]

Simplifying the fraction

[tex]\dfrac{\dfrac{y-x}{xy}}{\dfrac{y+x}{xy}}\\ =\dfrac{y-x}{xy}\times \dfrac{xy}{y+x}\\ =\dfrac{y-x}{y+x}[/tex]

The equivalent fraction is [tex]\dfrac{y-x}{y+x}[/tex]

Area of the semicircle = 509.004 cm²

When an arc of a circle with its endpoints on the diameter cuts a circle into two equal halves, those halves are called semicircles.

Given,

radius of semicircle = 18cm

π = 3.142

Area of the semicircle = πr²/2

                                     = 3.142 × 18×18/2

                                     = 3.142 × 18×9

                                     = 56.556×9

                                     = 509.004 cm²

Hence, 509.004 cm² is the area of the semicircle.
