all together is 62

Answer:

-16 =n

Step-by-step explanation:

Let n= number

4n -21 = 6n +11

Subtract 4n from each side

4n-4n -21 = 6n-4n +11

-21 = 2n+11

Subtract 11 from each side

-21-11 = 2n

-32 = 2n

Divide by 2

-32/2 = 2n/2

-16 =n

Answer : -16 =n

Step-by-step explanation:

Let n= number

4n -21 = 6n +11

Subtract 4n from each side

4n-4n -21 = 6n-4n +11

-21 = 2n+11

Subtract 11 from each side

-21-11 = 2n

-32 = 2n

Divide by 2

-32/2 = 2n/2

-16 =n

Answer:

2513.41 mm³

Step-by-step explanation:

Given that,

The diameter of ball 1 = 39.5 mm

Radius of ball 1 = 19.75 mm

The volume of ball 1 is :

[tex]V_1=\dfrac{4}{3}\pi r^3\\\\=\dfrac{4}{3}\pi \times 19.75^3\\\\=32269.32\ mm^3[/tex]

The diameter of ball 2, = 40.5 mm

Radius = 20.25 mm

Volume of ball 2,

[tex]V_2=\dfrac{4}{3}\pi \times 20.25^3\\\\=34782.73\ mm^3[/tex]

Difference in volume = V₂ - V₁

= 34782.73 - 32269.32

= 2513.41 mm³

So, the difference in volume of the ball is equal to 2513.41 mm³.

Answer:

Sample Space

Step-by-step explanation:

A set of all possible outcomes of an experiment is called a sample space. Sample space is simply the set of all possible sample points of a given experiment.

Hope this helps!

Answer:

We have the variables:

x = hours that she mows lawns per week.

y = hours that she babysits per week.

She earns $10 per hour mowing lawns and $8 per hour babysitting.

Then she earns a total of:

x*$10 + y*$8

We also know that she wants to earn at least $160 per week.

Then we have the inequality:

Total weekly earnings ≥ $160

This can be written as:

x*$10 + y*$8  ≥ $160

Now we want to find the x-intercept of the inequality.

The x-intercept is the possible y-values when x = 0 (the x-axis)

Then we just need to set x = 0 and find the possible solutions for y.

0*$10 + y*$8 ≥ $160

y ≥ $160/$8 = 20

y ≥ 20

The x-intercept of the inequality is the set of all the points (0, y) such that:

y ≥ 20

Answer:

(x - 5)² + (y - 2)² = 9

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r the radius

Here (h, k ) = (5, 2 ) and r = 3 , then

(x - 5)² + (y - 2)² = 3² , that is

(x - 5)² + (y - 2)² = 9

The radius of the circle is  17.54 cm

Consider an arc of a circle.

Suppose it subtends θ angle on the rest of the part of the circumference (at any point). Then it subtends 2θ angle on the center of that circle.

Given that Chord 12 cm long subtends an angle of 40 degrees at the center of a circle.

θ= 40° = 0.698 radian

Let R be the radius of circle.

Chord Length = 2Rsin(θ/2)

12=2R sin (0.698 /2)

R= 17.54

Hence Radius of circle = 17.54 cm

Answer:

4:10 PM

Step-by-step explanation:

The time at which the passenger train is 61.5 miles west of Kalamazoo and the freight train is now 49.5 miles east of Kalamazoo  4:10 pm

Speed is the ratio of distance travelled to time taken. It is given by:

Speed = distance / time

Let a represent the speed passenger train and b for the freight train.

The passenger train averages 16 miles per hour faster than the freight train, hence:

a = b + 16   (1)

Also:

a = 61.5/t

t = 61.5/a

b = 49.5/t

t = 49.5/b

61.5/a = 49.5/b

61.5b = 49.5a    (2)

From both equations:

a = 82 mph, b = 66 mph

t = 61.5/82 = 0.75 hour = 45 minutes

Time = 3:25 p.m + 45 minutes = 4:10 pm

The time at which the passenger train is 61.5 miles west of Kalamazoo and the freight train is now 49.5 miles east of Kalamazoo  4:10 pm

To find:

The correct values for the quadratic formula.

Solution:

If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then the quadratic formula is:

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

We have,

[tex]16x^2-20x-6=0[/tex]

Here, [tex]a=16,b=-20, c=-6[/tex]. Substituting these values in the above quadratic formula, we get

[tex]x=\dfrac{-(-20)\pm \sqrt{(-20)^2^2-4(16)(-6)}}{2(16)}[/tex]

Therefore, the quadratic formula for the given equation is [tex]x=\dfrac{-(-20)\pm \sqrt{(-20)^2^2-4(16)(-6)}}{2(16)}[/tex].
