The time taken by the family to reach is T = 7 hours
What is Speed?Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude
Speed = Distance / Time
Given data ,
Let the speed be represented as S
Now , the value of S is
S = D / T
speed = distance / time = 204 miles / 3.4 hours = 60 miles per hour
where , the distance D = 420 miles
And , T = 420 / 60
T = 7 hours
Hence , the time taken for 420 miles is 7 hours

how do you find the x-intercepts if given the following polynomial in factored form?
X(x-2)^2(x+4)(x+1)
Answer:
Step-by-step explanation:
You know the intercepts occur at x = 0, so set each part of the factored form equal to zero and solve for x.
The first part, plain X = 0, so X = 0 is a root, an x-intercept
The second part (X-2)^2 = 0, so X = 2 is another root. Since the function is being squared, this root will happen twice. The function crosses this root twice.
The third part (x+4) = 0, so x = -4 is another root.
Finally, (x+1) so x = -1 is another root.
So you have X = 0, X = 2, X = -4, X = -1 as your x-intercepts

6x - 18 = 2x + 10
4x = 28
x = 7
Answer:
x = 7
Step-by-step explanation:
In order to find the value of x, isolate it in the equation.
1) First, distribute the 2 to the terms inside the set of parentheses.
[tex]2 (3x - 9) = 2x + 10 \\6x - 18 = 2x + 10 \\[/tex]
2) Next, move all the x terms to one side and all the other terms to the other side. Subtract both sides by 2x and add both sides by 18.
[tex]6x - 18 = 2x + 10 \\4x = 28[/tex]
2) Divide both sides by 4 to finally isolate x.
[tex]4x = 28 \\x = 7[/tex]
Thus, x = 7.

How many vehicles are at Nam's Gas Station?
Answer:
23
Step-by-step explanation:
The number of car are in the y-intercept line so just add each one of the for every different bar.
3 + 4 + 5 + 6 + 3 + 2 = 23
So there are 23 vehicles in total.
The number of vehicles are at Nam's Gas Station is 23
Calculation of the number of vehicles:Since The number of cars are in the y-intercept line
So here the no of vehicles should be
= 3 + 4 + 5 + 6 + 3 + 2
= 23
Here we added according to the given graph
Therefore, we can conclude that The number of vehicles are at Nam's Gas Station is 23

Tamara finds the sum of two number cubes rolled at the same time. The chart below shows all possible sums from the 36 possible combinations when rolling two number cubes. How many times should Tamara expect the sum of the two cubes be equal to 4 if she rolls the two number cubes 216 times?
Answer:
18 times
Step-by-step explanation:
Sample space ; roll of 2 number cubes = 6^2 = 36
Sum of 4 in 2 cube rolls = 3
Probability = required outcome / Total possible outcomes
P(sum of 4) = 3 / 36 = 1 / 12
If number cube is rolled 216 times :
Probability on 1 roll * Number of rolls
(1 / 12) * 216
0.0833333 * 216
= 18

PLEASE HELP AND EXPLAIN YOUR ANSWER!
Answer:
24w - 16u + 48
Step-by-step explanation:
by distributive property you have to distribute the number on the outside to the number inside the parenthesis
Answer:
24w - 16u + 48
Step-by-step explanation:
Ok so,
to distribute means to multiply -8 with all of the numbers inside of the parentheses in order to get rid of it. So it should look like this.
-8 x -3w = 24w
-8 x +2u = -16u
-8 x -6 = 48
Now you just take all of the numbers and put them together which will be
24w - 16u + 48
