The distance between two towns is 600km,correct to the nearest 10km
A car takes 8 hours 40minute, correct to the nearest 10 minute, to travel this distance
Calculate the lower bound for the average speed of the car in km/h
Answer:
Below
Step-by-step explanation:
rate X time = distance
rate = distance / time <=====we want minimum of this so make denominator as large as possible and numerator as small as possible
distance = 595 KM ( rounds up to 600 km)
time = 8 hr 44 min rounds down to 8 :40 you could make it 8:44.99)
595 km / (8 + 44.99/60) hr = 68 km/hr

What is Simultaneous equation?Simultaneous equations are two or more algebraic equations that share variables e.g. x and y . They are called simultaneous equations because the equations are solved at the same time. For example, below are some simultaneous equations: 2x + 4y = 14 4x − 4y = 4.
Represent the number of children by x and the number of adult by y
this means;
x+y = 455 equation 1
1.75x + 2.5y = 952.25 equation 2
using substitution method,
x = 455-y
substitute 455-y for x in equation 2
1.75(455-y) + 2.5y = 952.25
796.25-1.75y+2.5y = 952.25
0.75y = 952.25-796.25
0.75y = 156
divide both sides by 0.75
y = 156/0.75
y = 208
substitute 208 for y in equation 1
x = 455-208
x = 247
therefore the number of children and adults in the pool are 247 and 208 respectively.

a steel plate contains 20 bolts. assume that five bolts are not torqued to the proper limit. four bolts are selected at random, without replacement, to be checked for torque. (a) what is the probability that all four of the selected bolts are torqued to the proper limit?
The probability that all four of the selected bolts are torqued to the proper limit is approximately 0.28.
To calculate the probability that all four of the selected bolts are torqued to the proper limit, we need to find the number of combinations of 4 bolts out of 20 that have been torqued to the proper limit.
Let's call the number of proper bolts n = 20 - 5 = 15.
The number of combinations of 4 proper bolts out of 15 is given by the binomial coefficient nCk, where n is the number of bolts and k is the number of bolts selected.
nCk = n! / (k! (n - k)!).
So, the number of combinations of 4 proper bolts out of 15 is:
15C4 = 15! / (4! (15 - 4)!) = 15! / (4! 11!) = 1365.
Therefore, the probability of selecting all 4 proper bolts out of 20 is:
P = number of combinations of 4 proper bolts / number of combinations of 4 bolts = 1365 / 20C4 = 1365 / 4845 = 0.28
So, the probability that all four of the selected bolts are torqued to the proper limit is approximately 0.28.

there are c different types of coupon, and each coupon obtained is equally likely to be any one of the c types. find the probability that the first n coupons which you collect do not form a complete se
The probability that the first n coupons which you collect do not form a complete set is (c^n - (c-1)^n) / c^n.
To find the probability that the first n coupons collected do not form a complete set, we need to count the number of ways in which the first n coupons can be collected so that they do not form a complete set and divide it by the total number of ways in which n coupons can be collected, which is c^n.
Let S be the set of all possible complete sets of coupons. The number of ways in which the first n coupons can form a complete set is the number of ways to choose any one of the complete sets in S, multiplied by the number of ways to order the coupons within that set. There are (c choose n) ways to choose n coupons out of c, and for each complete set of n coupons, there are n! ways to order them. Therefore, the number of ways to choose n coupons that form a complete set is (c choose n) * n!.
The total number of ways to choose n coupons out of c is c^n.
So, the probability that the first n coupons collected do not form a complete set is:
P = 1 - [(c choose n) * n! / c^n]
Alternatively, we can count the number of ways in which the first n coupons can be collected so that they do form a complete set. There are (c-1)^n ways to choose n coupons out of c-1 types of coupons, and for each set of n coupons, there is exactly one way to add the missing coupon to form a complete set. Therefore, the number of ways to choose n coupons that form a complete set is c^n - (c-1)^n.
So, the probability that the first n coupons collected do not form a complete set is:
P = (c^n - (c-1)^n) / c^n

The required equation represents the inverse function b(a), which takes the trapezoid's area is B(a) = a/6 - 9.
What is a trapezoid?A trapezoid is a quadrilateral having two parallel bases and one set of other sides called as legs.
We have been given that the trapezoid's base is nine and its height is twelve.
As an outcome, 'b' is the base's parallel side.
The function that represents the trapezoid's area is given by:
A(b) = [12(b + 9)]/2
Let's consider A(b) = a
Then, a = [12(b + 9)]/2
Now solving for b, we get
2a = 12(b + 9)
a = 6(b + 9)/2
a = 6b + 54
6b = a - 54
b = (a - 54)/6
b = a/6 - 9
Assuming that the length of the side parallel to the base 'b' = B(a), the equation will be:
B(a) = a/6 - 9
Thus, the correct answer would be option A. B(a) = a/6 - 9.

John can buy any amount of chocolate between 0 and 2.2 pounds (rounded to one decimal place) and still have enough money to buy the jelly beans.
John brings $15 to the candy store and buys a bag of jelly beans for $4. He plans to buy some chocolate that costs $5 per pound. Let x be the number of pounds of chocolate John could buy.
The cost of the chocolate John plans to buy is $5 per pound, so the total cost of x pounds of chocolate is 5x. John's total budget is $15, so he must have enough money to buy the jelly beans and the chocolate. Therefore, the inequality that represents this situation is:
4 + 5x ≤ 15
To solve for x, we can begin by isolating the variable on one side of the inequality. We can do this by subtracting 4 from both sides of the inequality:
5x ≤ 11
Next, we can isolate x by dividing both sides of the inequality by 5:
x ≤ 11/5
Therefore, the possible values of x, the number of pounds of chocolate John could buy, are all real numbers less than or equal to 11/5. However, since John cannot buy a negative amount of chocolate, we must also restrict x to be greater than or equal to 0. Therefore, the solution to the inequality is:
0 ≤ x ≤ 11/5

The equation is......
It will take.....days for the water level to be 26 feet.
The equation is y = (-0.5)x + 34 and it will take 16 days for the water level to be 26 feet.
What is equation?A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("="). For illustration, 2x - 5 = 13.
Two expressions are combined in an equation using an equal symbol ("="). The "left-hand side" and "right-hand side" of the equation are the two expressions on either side of the equals sign. Typically, we consider an equation's right side to be zero.
Let the number of days = x, and the water level = y.
Given that,
Water level of river = 34 ft (initial value/y-intercept)
Rate of change = -0.5 ft per day (slope)
The equation of the line is given as:
y = mx + c
where, m is the slope
c is the y-intercept.
Substituting the values we have:
y = (-0.5)x + 34
The number of days in which the water level will reduce to 26 ft is:
26 = (-0.5)x + 34
26 - 34 = -0.5x
x = 16 days.
Hence, it will take 16 days for the water level to be 26 feet.
