Equivalent fractions are fractions that represent the same value or amount, despite having different numerators and denominators.

In other words, equivalent fractions have the same ratio or proportion, but may be written in different forms.

For example, the fractions 1/2 and 2/4 are equivalent fractions because they represent the same amount, which is half of a whole.

Also, 3/5 and 6/10 are equivalent fractions because they both represent three-fifths or 60% of a whole.

Answer:

A≈78.5

Step-by-step explanation:

Formula : pie * r^2

3.14 * 5^2

3.14 * 25

78.5

= ( 3x² + 3x + 5 ) ( 6x + 4 )

= 18x³ + 18x² + 30x + 12x² + 12x + 20

= 18x³ + 30x² + 42x + 20

Answer:

The answer is "19.77%"

Step-by-step explanation:

Given:

[tex]\mu = 19.7\\\\ \sigma = 2\\\\\to P(x >21.4 ) = 1 - P(x< 21.4)\\\\[/tex]

                        [tex]= 1 - [\frac{P(x -\mu)}{ \sigma }< \frac{(21.4-19.7)}{2}]\\\\= 1 - P(z < 0.85)\\\\= 1 - 0.8023\\\\=0.1977\\\\=19.77\%[/tex]

Answer:

Step-by-step explanation:

Mean: all the numbers added then divided by the total number of numbers

[tex]m=\frac{2+2+3+3+3+4+5+5+5+6+8+14}{10}\\m= \frac{60}{10}\\\\m=6[/tex]

Mode: number(s) that is most often listed in the list of numbers.

Answer:

12   never     mind it is 72

Step-by-step explanation:

6x6=36

36x2=72

Answer:

6 x 6

Step-by-step explanation:

because when You multiply x2 is by the same number

so it's 6 x6 = 36

Answer:

H = 42

Step-by-step explanation:

18 ÷ 108 = [tex]\frac{1}{6}[/tex]

7 ÷ [tex]\frac{1}{6}[/tex] = 42

You can check to make sure your answer is right by entering your proportions into a calculator. For example, [tex]\frac{42}{108}=0.38888888888...[/tex] and [tex]\frac{7}{18}[/tex] also equals [tex]0.38888888888...[/tex] so since they match, we know it is correct.

Answer:

0.058863

Step-by-step explanation:

Answer: 160 children and 174 adults

Step-by-step explanation:

Let x represent the children and y represent the adults.

Create two equations:

x+y=334

1.50x+2y=588

Subtract 1.50x from the equation, then divide by 2:

y=294 - 0.75x

Plug it into the first equation then solve.

x+294-0.75x=334

x=160

Subtract 160 from 334 to get y:

y=174

Answer:

No, 10/24 is not equal to 8/20

Step-by-step explanation:

Answer:

x=29

Step-by-step explanation:

3x-8 is an exterior angle so we use the exterior angle theorem to solve this problem

3x-8=2x+21

x=29

Answer:

k = -2

Step-by-step explanation:

2 way to solve:

1st: 8x²-13x-4k = 8(x²-(13/8)x-(k/2))

if 2 roots: a and 1/a

8(x-a)(x-1/a) = 8(x²-(13/8)x-(k/2))

x²-(a+1/a)x+1 = x²-(13/8)x-(k/2)

1 = -(k/2)

k = -2

2nd: 2 roots of 8x²-13x-4k      x=(-b±√b²-4ac)/2a

x = (13±√169-4*8*(-4k))/16 = (13±√169+128k)/16

(13+(√169+128k))/16 = 16/ (13-(√169+128k))  ... root1=1/root2

(13+(√169+128k))*(13-(√169+128k)) = 16*16

13² - (√169+128k)² = 256

169-169-128k = 256

-128k = 256

k = -2

Answer: what?

Step-by-step explanation:

I don’t know

Answer:

Just multiple each fraction by 2 on the denominator and numerator.

For the drawing part, all you have to do is draw lines until you get the number of the denominator.

Step-by-step explanation:

For. Example, 2/4 times 2 equals 4/8

So for this u would draw lines till you count that there are 8 lines.

I hope this helped you.

Have a nice day.

Answer:

192.5 ft²

Step-by-step explanation:

Area of the shaded region (A) = Area of the major sector + Area of the triangle.

A = (πr²θ/360)+(r²sinα)/2............. Equation 1

From the diagram,

Given: r = 8.35 ft, α = 100°, θ = 360-100 = 260°

Substitute these values into equation 1

A = (3.14×8.35²×260/360)+(8.35²×sin100×1/2)

A = 158.16+34.33

A = 192.49 ft²

A  = 192.5 ft²

Hence the area of the shaded region = 192.5 ft²

Answer:

x² - 3x + 0.25 = 0

Step-by-step explanation:

Given a root x = a then the corresponding factor is (x - a)

Given roots x = 1.5 + [tex]\sqrt{2}[/tex] and x = 1.5 - [tex]\sqrt{2}[/tex] then the factors are

(x - (1.5 + [tex]\sqrt{2}[/tex] ) ) and (x - (1.5 - [tex]\sqrt{2}[/tex] ) ) , that is

(x - 1.5 - [tex]\sqrt{2}[/tex] ) and (x - 1.5 + [tex]\sqrt{2}[/tex] )

The equation is then the product of the factors

(x - 1.5 - [tex]\sqrt{2}[/tex] )(x - 1.5 + [tex]\sqrt{2}[/tex] ) = 0 ← expand factors using FOIL

(x - 1.5)² - ([tex]\sqrt{2}[/tex] )² = 0

x² - 3x + 2.25 - 2 = 0

x² - 3x + 0.25 = 0

Answer:

The answer is D.

Step-by-step explanation:

28/7 = 4 and 19-4 = 15.

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

Explanation:

We're told that 1 square foot is 144 square inches (this is from 12*12 = 144, since 12 inches = 1 ft).

So because of this, 360 square feet converts to 360*144 = 51,840 square inches.

One gallon of paint can cover 51,840 square inches.

Now let's find the surface area of the sphere, aka ball.

It has a radius of r = 4.75 inches, so,

SA = 4*pi*r^2

SA = 4*pi*(4.75)^2

SA = 90.25pi

SA = 283.528736986479 which is approximate

The surface area of one ball is roughly 283.528736986479 square inches.

Divide the amount of area the paint can cover over the surface area of one basketball:

(51,840)/(283.528736986479) = 182.838609415709

This rounds down to 182. We round down because we won't have enough paint to cover the 183rd basketball.

One gallon of paint can cover 182 basketballs.

Answer:

(1) article 6 : coffee may show slow decline in women.

(2) Description:

study by ishani gungali.

Mon august 6 ,4:56 PM ET

Washington ( Reuters): consumption of more than 3 cups coffee protect older women against some

age related memory decline. although it does not effects men's the same way.

(3) I womens those who have 3 or more cups of coffee than those of having 1 or fewer cups of coffee has lower odds of 33% of memory loss and 18 % visual and spatial decline. Also women it is seen that 80 repeaing women's are more benefits in comparison of who were 10 to 15 year younger.

(4) Karen Ritchie at the French National institute of Medical Research whose work appears in the journal neurology.

(5) Reading the above article I came to acknowledge that the women's only benefiting has to do something the way it metabolizes in them unlike in men's.

(6) lifestyle choices may protect one with mild form of age related memory loss from future decline. Essentially what is healthy for body is healthy for brain.

Step-by-step explanation:

Answer:

The missing numbers are 12 and 39 respectively

Step-by-step explanation:

From the table, we can see that the ratio of the left column to the right is 3/5

So at any point in time, the values on a particular row of the table must conform

to this ratio

In other light, we have to multiply what we have on the left by 5/3 to get what’s on the right

and we have to multiply what we have on the right by 3/5 to get what’s on the left

We have this as follows;

20 * 3/5 = 12

and;

65 * 3/5 = 39

Answer:

x=2

Step-by-step explanation:

Answer:

The sum is;

x⁸ + x²

Step-by-step explanation:

Here, we want to add two polynomials

To add, we check the power of both values in the expression

As we can see, the power is not the same

What this mean is that we can not add the two terms beyond this written expression

So we have the value of the polynomial expression as still being the same

no solution is the answer

Answer:

180000

Step-by-step explanation:

Solve

Given: Both Raised $240,000, Blin raised $60,000 more than Alex

To find: How much money Blin raised

Firstly, since two people raised that amount, divide the amount by 2 of them

240,000 ÷ 2 = 120,000

Nextly, subtract 60,000 from Alex's share; because Brin has more so Alex has less, less means subtract.

120,000 - 60,000 = 60,000

Now, Add that amount to Brin's share; again, Brin has more so Alex has less, less means subtract.

60000 + 120,000 = 180,000

Therefore, Brin raised $180,000

Confirm: 180,000 + 60,000 = 240,000

(For your information, Alex has $60,000)
