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

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

Answer:

-36

Step-by-step explanation:

We were given the expression as

(c3+d2)

Where our

c=-4

Then d= 10

Then substitute for the values of "c and d" in given expresion, we have

(c3+d2)

(-4)^3 + (10)^2

=-64 + 100

= -36

Answer:

x = 3

Step-by-step explanation:

Solution: Shift all alphabets to one side and numbers/fractions to the other side.

Shift 1/4 to the other side, it'll become negative.

5x = 61/4 - 1/4 = 60/4

5x = 60/4

x = 60/4 ÷ 5 = 3

Answer: 19.26

Step-by-step explanation: 40% of 30 can be found like 30(0.40), which equals 12, since the game is 40% of they are getting $12 off. 30-12=18. The sales tax is 7% or 0.07 so you can find it by doing 18(0.07) which is 1.26, now you just add 1.26 and 18 which is 19.26.

bceuse  8 is the radius

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.

Given:

The quadratic equation is:

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

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].

Answer:

D since I had a test question of this and got it right.

Step-by-step explanation:

Option D is correct, credit cards can help you stay within budget since you can't spend more than what's in your linked bank account.

A credit card is a payment card issued to users to enable the cardholder to pay a merchant for goods and services based on the cardholder's accrued debt.

Credit cards can help you stay within budget since you can't spend more than what's in your linked bank account is not accurate because credit cards actually allow users to spend more than what's in their linked bank account, which can lead to overspending and accumulating debt.

Unlike debit cards, which are linked directly to a checking account, credit cards allow users to borrow money from a lender up to a certain credit limit.

This means that users can potentially spend more than they have available in their bank account and then pay off the balance over time with interest.

Hence, Option D is correct, credit cards can help you stay within budget since you can't spend more than what's in your linked bank account.

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:

-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
