Answer:

20 years apart.

Step-by-step explanation:

Daughter is 10 years old, and mother is 3 times older. This makes mother 30 years old.  There is a 20 year difference between them.

Ten years later, the daughter is 20 years old. Since the mother is 20 years older, she is now 40, which is 2 times older than the daughter.

Jason rolls a fair number cube labeled 1 through 6, and then he flips a coin. What is the probability that he rolls a 3 and flip
qwelly [4]

The answer is 1/12

The chance of getting a 3 on a six-sided dice is 1/6

The possibility of getting heads on a two-sided coin is 1/2

6 multiplied by 2 is 12

1 multiplied by 1 is 1

Hope it helps!

John and Elijah are both driving from New York City to Richmond. John leaves
alina1380 [7]

Elijah will pass John after 5 hours, and they each will have traveled 310 miles. Then the correct option is C.

<h3>What is speed?</h3>

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.

We know that the speed formula

Speed = Distance/Time

John and Elijah are both driving from New York City to Richmond.

John leaves at 7:20 and averages 60 mph (miles per hour) on the way.

Elijah leaves at 7:30 and averages 62 mph on the way.

The situation is modeled by this system, where x is the number of hours after Elijah leaves and y is the distance each will travel.

y = 60x + 10 ...1

y = 62x        ...2

The time is taken by Elijah to cross John will be

62x = 60x + 10

 2x = 10

   x = 5 hours

The distance traveled in 5 hours will be

y = 62 (5)

y = 310 miles

Elijah will pass John after 5 hours, and they each will have traveled 310 miles.

Then the correct option is C.

More about the speed link is given below.

Explain how you could write a quadratic function in factored form that would have a vertex with an x-coordinate of 3 and two dis
skad [1K]
<span>The definition of quadratic function is given by:

</span>(1) \ f(x)=ax^{2}+bx+c \\ \\ where \ a, b, c \ are \ real \ values<span>

So the problem asks for two conditions:

<em>1. Write the quadratic function in factored form. </em>
<em>2. The vertex has an x-coordinate of 3.</em>

Then the equation (1) must be written as follows:

</span>f(x)=(x-m)(x-n) \\ \\ where \ m \ and \ n \ are \ the \ roots<span>

To satisfy the two conditions:

\frac{m+n}{2}=3

So we are free to choose the value of one root, say:

m=1

Thus:

n=6-1=5

Finally, the answer is:

f(x)=(x-1)(x-5)

The graph of this function is shown in the figure below.</span>

A positive integer is 11 more than 18 times another. Their product is 6030. Find the two integers.
allsm [11]

Answer:

18 and 335

Step-by-step explanation:

y = 18x + 11

x * y = 6030

x * (18x + 11) = 6030

18x^2 + 11x = 6030

18x^2 + 11x - 6030 = 0

(18x + 335)(x - 18) = 0

18x + 335 = 0                 x - 18 = 0

18x = -335                      x = 18

x = -335/18

x is gonna have to be a positive number...so x = 18

y = 18x + 11

y = 18(18) + 11

y = 324 + 11

y = 335

so ur numbers are 18 and 335
