Answer:
They will meet in 7 hours.
Step-by-step explanation:
They are traveling toward each other, which means that their relative speed is the sum of their speeds.
Bill travels 20 mph and Michael travels 14 mph
This means that their relative speed is of 20 + 14 = 34 mph, that is, they get 34 miles closer each hour.
Michael and Bill are 238 miles apart, how long until they meet?
Each hour, they will be 34 miles closer. How many hours for 238 miles?
1h - 34 miles
x h - 238 miles
By rule of three
[tex]34x = 238[/tex]
[tex]x = \frac{238}{34} = 7[/tex]
They will meet in 7 hours.
The points (0,4) and (1, 9) fall on a particular line. What is its equation in slope-intercept
form?
Answer:
The equation is y = 5x + 4.

Step-by-step explanation:
☆Remember: [tex]m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
☆Slope-intercept: [tex]y = mx + b[/tex]
---
☆We need to find the slope first. So just plug in according to the slope formula!
[tex]m = \frac{9 - 4}{1 - 0} = \frac{5}{1} = 5[/tex]
---
☆Now we need to find the y-intercept. We are going to plug in the slope and a set of coordinates to find the y-intercept.
[tex]y = mx + b \\ 9 = 5(1) + b \\ 9 = 5 + b \\ \frac{ - 5 = - 5 \: \: \: \: \: \: \: \: \: \: \: \: }{4 = b \: \: \: \: \: \: \: \: \: } [/tex]
---
☆Now all we need to do is plug in and we are done!
[tex]y = 5x + 4[/tex]

Answer:
y = 0.2·0.5^x
Step-by-step explanation:
An exponential function is generally of the form ...
y = a·b^x
where 'a' is the function value when x=0, and b is the ratio between values for x=1 and x=0.
In the given table, y = 0.2 for x = 0, so a = 0.2.
We find that the value for x = 1 is 0.1, so the value of b is ...
b = 0.1/0.2 = 0.5
Then the exponential function is ...
y = 0.2·0.5^x

Written as a simplified polynomial in standard form, what is the result when
(2x + 2)2 is subtracted from 1?
Answer:
[tex]1-(2x+2)^2=-4x^2-8x-3[/tex]
Step-by-step explanation:
Polynomials
Simplify the result of:
[tex]1-(2x+2)^2[/tex]
Expanding the square of the binomial:
[tex]1-(2x+2)^2=1-[(2x)^2+2(2x)2+2^2][/tex]
Operating:
[tex]1-(2x+2)^2=1-(4x^2+8x+4)[/tex]
[tex]1-(2x+2)^2=1-4x^2-8x-4[/tex]
Collecting like terms:

Explain what is the difference between the solutions to 2x=10 and 2x > 10
Answer:
See explanation below
Step-by-step explanation:
Explain what is the difference between the solutions to 2x=10 and 2x > 10
Given the equations;
2x = 10
x = 10/2
x = 5
For the equation 2x > 10
x > 10/2
x > 5
The first equation has only one solution which is 5 while the second equation has infinite number of solutions since the values of x can take any value that is greater than 5
The line passes through the point (-7,-5) and has slope of -8
Answer:
[tex]y=-8x-61[/tex]
Step-by-step explanation:
The slope-intercept form of the equation is y=mx+b where m is the slope and b is the y intercept. We know so far, that the slope is -8. We plug that in for m.
[tex]y=-8x+b[/tex]
Now, we need to find the y-intercept. The question gives us the point (-7,-5). We plug in -7 for x, and -5 for y.
[tex]-5=-8(-7)+b[/tex]
Then, we solve.
[tex]-5=56+b[/tex]
Subtract 56 from both sides.
[tex]-61=b[/tex]
Finally, we get this equation:
y=-8x-61

Noah bought a digital camera for $90. The tax rate is 6%.
What is the total amount Noah paid for the digital camera?
Answer:
$95.4
Step-by-step explanation:
6% in decimal form is 0.06
we need to find what 6% of 90 is to see how much sales tax there is on this item
0.06*90=5.4
the sales tax is 5.4
5.4 is 6% of 90 so we need to add 5.4 to 90
90+5.4=95.4
$95.4---total amount noah paid(normal price+ sales tax)

Calculate the probability that 200 rolls of two dice rolls will include
a) more than 30 sums of 5
b) between 30 and 40, inclusive, sums of 5
Answer:
[tex]P_x=0.7407407407 \approx 0.74[/tex]
Step-by-step explanation:
From the question we are told that
Dice rolls n=200
Number of dice =2
Generally sample space for Two 6-sided dice is [tex]n=36[/tex]
The sums of five bears the following events
[tex]E={(1,4)(2,3)(3,2)(4,1)}=>4[/tex]
Probability of getting a sum of 5 in a roll
[tex]P(sum 5)=\frac{4}{36}[/tex]
Generally the probability that two dice rowed will include 30 sums of 5
[tex]P_x=\frac{4(200)}{36(30)}[/tex]
[tex]P_x=0.7407407407 \approx 0.74[/tex]
The probability of getting more than 30 sums of 5 out of 200 rolls is 1/6.
What is probability?Probability is the measurement of possibilities.
Number of rolls =200
Number of dice =2
Sample space for a sum of 5 will be (1,4) (2,3), (3,2),(4,1)
Total outcomes = 36
So, the probability of getting 5 as a sum in a single roll= 4/36 =1/9
So, the probability of getting more than 30 sums of 5 out of 200 rolls
= 1/9 *30/200
=1/6
Hence, the probability of getting more than 30 sums of 5 out of 200 rolls is 1/6.
