What is the product? 3 1/2 × 2 2/3

Answer:

center : (0, 2.25)

radius: 14/13

Step-by-step explanation:

x^2+(y-2.25)^2=196/169

Rewrite x^2+(y-2.25)^2=196/169

(x-0)^2+(y-2.25)^2=(14/13)^2

c=(0,2.25),r= (14/13)

hope this helps<3

Final answer:

The center of the circle described by the equation is at (0, 2.25), and its radius is 14/13 units.

Explanation:

The equation given is x^2 + (y-2.25)^2 = 196/169. This equation is of the form (x-h)^2 + (y-k)^2 = r^2, where (h, k) is the center of the circle, and r is the radius. To find the center and radius, we compare the given equation to the standard form.

Center: By comparison, h=0 and k=2.25, so the center is at (0, 2.25).

Radius: The radius is the square root of 196/169, which is 14/13. Therefore, the radius is 14/13 units.

Step-by-step explanation:

Answer:

sum

Step-by-step explanation:

We know that, 'multiplication of two or more quantities can be expressed as the SUM of the same quantities'.

This means that 'multiplication of two or more terms is equal to adding as many copies of one of them'.

i.e. a × b = a + a + .... ( 'b' number of times ) = b + b + ... ( 'a' number of times )

Let us consider few examples,

A.  2 × 4 = 8

So, we can have that,  

2 × 4 = 2 + 2 + 2 + 2 = 8 i.e. we add the number 2 four times.

2 × 4 =  4 + 4 = 8 i.e. we add the number 4 two times.

B. 3 × 7 = 21

3 × 7 = 3 + 3 + 3 + 3 + 3 + 3 + 3 = 21 i.e. we add the number 3 seven times.

3 × 7 = 7 + 7 + 7 = 21 i.e. we add the number 7 three times.

Hence, 'The multiplication of two or more quantities may be expressed as the SUM of the same quantities'.

Answer:

d

0(10 - 0) = 0 × 10 = 0 < 4 → 0 is not a solution

Answer:

Final answer:

To find the quotient of 3 ÷ 2 1/3, convert the mixed number to an improper fraction (7/3), find the reciprocal (3/7), and multiply it by 3 to get 9/7, which is the answer in lowest terms.

Explanation:

The quotient of 3 ÷ 2 1/3 can be found by first converting the mixed number 2 1/3 to an improper fraction. The mixed number 2 1/3 is equal to ⅔, which when summed (2 * 3 + 1), gives us 7/3. To divide by a fraction, you multiply by its reciprocal. Thus, we have 3 × ⅓ (which is 3/7). Multiplying these we get 9/7, which cannot be further simplified. Therefore, the quotient in lowest terms is 9/7.

The quotient of 3 ÷ 2 1/3 is found by converting 2 1/3 to an improper fraction (7/3), taking the reciprocal (3/7), and multiplying it with 3. The result is the fraction 9/7, which is already in lowest terms.

To find the quotient of 3 ÷ 2 1/3, we first convert the mixed number to an improper fraction. The mixed number 2 1/3 is equivalent to 7/3 (because 2 × 3 + 1 = 7). To divide by a fraction, we multiply by its reciprocal. Therefore, we need to multiply 3 by the reciprocal of 7/3, which is 3/7.

The multiplication is straightforward: 3 × 3/7. We multiply the numerators (3 × 3) to get 9, and the denominators (1 × 7) to get 7, so we have 9/7. Since 9 and 7 have no common factors other than 1, 9/7 is already in its lowest terms. Thus, the quotient is 9/7 or 1 2/7 when expressed as a mixed number.

Step-by-step explanation:

Answer: x = 2  11/36

Step-by-step explanation:

x-2 1/4 = 1/18

Isolate x: x - 2 1/4 + 2 1/4 = 1/18 + 2 1/4

x = 4/72 + 2 18/72

x = 2 22/72

x = 2 11/36

Check:

2 11/36 - 2 1/4 = 1/18

2 11/36 - 2 9/36 = 1/18

2/36 = 1/18

1/18 = 1/18

Answer:

Jacket A would be $86 and

Jacket B would be $12.. You would add them together and get the $98..

Step-by-step explanation:

Answer:

Equation:

xᵃ + xᵇ= 98

xᵃ=xᵇ-12

Jacket A costs $43

Jacket B costs $55

Step-by-step explanation:

We have 2 equations

Knowing

xᵃ= cost of jacket A

xᵇ= cost of jacket A

xᵃ + xᵇ= 98

xᵃ=xᵇ-12

If we replace xᵃ in the first equation

xᵇ-12 + xᵇ= 98

2xᵇ-12= 98

2xᵇ=98+12=110

xᵇ=110/2=55

xᵇ=55

xᵃ=xᵇ-12

xᵃ=43

For a 30 second flight, the airplane will travel 4.5 miles. To cover a distance of 12.75 miles, it will take 85 seconds.

The relationship between the distance an airplane travels and the time it takes is given by the equation [tex]d=0.15t[/tex].

Here, d stands for distance in miles and t for time in seconds. The coefficient 0.15 in this equation represents the speed of the airplane in miles per second.

To find how fast the airplane is flying, we must convert this speed to a more familiar unit, such as miles per hour.

Since there are 3600 seconds in one hour, the airplane's speed in miles per hour (mph) is

[tex]0.15 miles/second \times 3600 seconds/hour = 540 mph[/tex]

Now, to determine how far the airplane will travel in 30 seconds, we substitute t with 30 in the original equation:

[tex]d = 0.15 \times 30[/tex], yielding a distance of 4.5 miles.

To calculate how long it will take the airplane to go 12.75 miles, we use the original equation but solve for t:

[tex]t = \frac{d}{0.15} t = \frac{12.75}{0.15}[/tex]

which simplifies to 85 seconds.

Answer:

2 and 3/4 lbs

Step-by-step explanation:

4 and 1/2 is equal to 9/2. If you multiply 4 by 2 and then add 1, you get 9, and put it over 2 because that is the denominator in the mixed number. Using the same method, we can find that 1 and 3/4 is equal to 7/4. However, the denominators are different, so we need to change that so they will be common. We can change 9/2 to 18/4 by multiplying both the numerator and the denominator by 2. This is technically the same as multiplying by 2/2, which is equal to 1, so the fraction will be equivalent, since anything multiplied by 1 is itself. Now we have 18/4 for the large carton and 7/4 for the small carton. Since the denominators are the same, they do not change. Just subtract the numerators to get 11, and then put it over 4 to get 11/4. In mixed number form, this is 2 and 3/4 lbs because 4 goes into 11 twice (8) and then you will have 3 left over. 8+3 = 11

Step-by-step explanation:

We are given the following information in the question.

The line passes through the point (6,6) and (-6,1).

We have to find the point slope form of the equation.

The point slope form of equation is given by:

[tex]y-y_1 = m(x-x_1)\\\text{where}\\m = \displaystyle\frac{y_2-y_1}{x_2-x_1}\\\\\text{Putting}\\(6,6) = (x_1,y_1), (-6,1) = (x_2,y_2)\\\\y - 6 = \frac{1-6}{-6-6}(x - 6)\\\\y-6 = \frac{-5}{-12}(x-6)\\\\12(y-6) = 5(x-6)\\12y - 72 = 5x - 30\\12y = 5x -30 + 72\\12y = 5x +42\\\\y = \frac{5}{12}x + \frac{42}{12}\\\\y = \frac{5}{12}x + \frac{21}{6}[/tex]

The above equation is the required slope intercept form of equation passing through the given points.

Answer:

150 miles

Step-by-step explanation:

If they drove the same speed throughout the trip, we can find the speed from

d= rt

Solving for r

d/t =r

300 miles/ 6 hours = r

50 miles per hour = rate ( or speed)

On the last day, the drove 3 hours.

d =rt

d = 50 miles per hour * 3 hours

d = 150 miles

Answer:

The area of figure is 304 square unit.

Step-by-step explanation:

The figure divided into 2 equal trapezoids.The height of each is 8. The basis of each trapezoid are 14 and 24. It means the length of the parallel sides are 14 and 24.

Area of a trapezoid is

[tex]A=\frac{a+b}{2}\cdot h[/tex]

Where, a and b are length of parallel sides and h is the height of trapezoid.

Area of a trapezoid is

[tex]A_1=\frac{24+14}{2}\times 8[/tex]

[tex]A_1=19\times 8[/tex]

[tex]A_1=152[/tex]

Therefore area of a trapezoid is 152.

The area of figure is twice of area of a trapezoid.

[tex]A=2\times A_1=2\times 152=304[/tex]

Therefore the area of figure is 304 square unit.

Answer:

To find the axis of symmetry.

A quadratic equation is in the form of :

[tex]ax^2+bx+c =0[/tex] where a, b and c are coefficients and x is the variable

Axis of symmetry is given by :

[tex]x = -\frac{b}{2a}[/tex]

First identify a, b and c in the equation

[tex]f(x) = 3x^2[/tex]

⇒ a= 3 , b= 0 and c =0

[tex]g(x) = x^2-4x+5[/tex]

⇒ a = 1 , b = -4 and c =5

and

[tex]h(x) = -2x^2+4x+1[/tex]

⇒ a = -2 , b =4 and c =1

Using above formula of the axis of symmetry:

[tex]x = -\frac{b}{2a}[/tex]

then;

In f(x)

Axis of symmetry: [tex]x = -\frac{0}{2 \cdot 3} = 0[/tex]

Total surface area =61.23 in ^2

Step-by-step explanation:

To find the total surface area of a cylinder, we use the formula

T . S . A . = 2 π r h + 2 π r^ 2

where r is the radius and h is the height

We know the radius is 1.5 and the height is 5

Substituting the values into the equation

T . S . A . = 2 π (1.5)(5) + 2 π (1.5) ^2

                  = 15  π +4.5  π

                   = 19.5  π

Using 3.14 for  π

                   = 19.5 * (3.14)

                  =61.23 in ^2

To find the new width of the photo, we can use the concept of proportions. Let's set up the proportion:

Original Height / Original Width = Reduced Height / New Width

Plugging in the given values, we have:

16 in / 8 in = 4 in / x

Cross multiplying, we get:

16x = 32

Dividing both sides by 16, we find:

x = 2
