The average speed of the runner is 12.7 mph and 20.4 km/h
Given that the runner ran 26.2 mile in 2hr and 4 minutes, we start of by converting the time from hours and minutes into minutes and finally hours, since hours is what we need. So, we have
2hr = 120mins
+ 4 mins = 124 mins
124 mins ÷ 60 hour/mins = 2.06 hours.
This means that the runner finished the race in 2.06 hours.
If we are to find the average speed in mile per hour, we have
Average speed = distance ran ÷ time taken
Average speed = 26.2 ÷ 2.06
Average speed = 12.7 mph
From the speed in mph, we can directly convert it to km/hr by saying
1 mph = 1.609 km/h
12.7 mph = 12.7 * 1.609 = 20.4 km/hr

If the length of a sea turtle is
directly proportional to its age,
and a 2-year old sea turtle is 3
inches long, how many feet long
is a 80-year old sea turtle?
Answer:
10 feet
Step-by-step explanation:
Let the length and the age of the sea turtle be L inches and A years old respectively.
Since its length is directly proportional to its age,
L= kA, where k is an unknown constant.
Let's find the value of the constant k.
L= kA
When L= 3, A= 2,
3= k(2)
2k= 3
k= 3 ÷2
[tex]k = \frac{3}{2} [/tex]
Substitute the value of k back into the equation:
[tex]L = \frac{3}{2} A[/tex]
When A= 80,
[tex]L = \frac{3}{2} (80)[/tex]
L= 120
Length of sea turtle
= 120 inches
= (120 ÷12) feet
= 10 feet

1. Successive y-values have neither a common difference nor a common ratio. The table is neither linear nor exponential.
__
2. Successive y-values differ by 4. The table is linear.
__
3. Successive y-values have a ratio of 3. The table is exponential.
_____
Additional comment
For evenly-spaced x-values, the y-values will have a common difference for a linear function, and a common ratio for an exponential function.
If the table can be represented by a polynomial function, the level at which differences are constant will tell the degree of the polynomial. First differences are constant for a degree 1 (linear) function. Second differences are constant for a degree 2 (quadratic) function. This is the case in Table 1, where second differences are 2.

Let y = total hours Suzette biked. Use substitution to solve for x and y. Show your work. Check your solution. (a) How many hours did Suzette run? (b) How many hours did she bike? Answer:
Answer:
answer
First we need to write system of 2 equations with 2 variables:
x*6 + y*12.5 = 34
x+y = 3.5
for substitution we express one of variables in one of equations and put it in other equation.
x = 3.5-y
(3.5 - y)*6 + 12.5*y = 34
21 - 6y + 12.5y = 34
6.5y = 13
y = 2
x = 3.5 - y = 3.5 - 2 = 1.5
she ran for 1.5 hours and biked for 2 hours.
check:
1.5*6 + 2*12.5 = 9 + 25 = 34 = 34

The length and breadth of the plot in metres are in the ratio 10:3.The perimeter
of the plot is 312 m.
Answer:
I hope this could be of good assistant
Step-by-step explanation:
L:B = 10:3
make L subject of formula
L = 10B/3
perimeter = 312
2( L + B ) = 312
L + B = 312/2
L + B = 156
10B/3 + B = 156
multiply all through by 3
10B + 3B = 156 X 3
10B + 3B = 468
13B = 468
B = 468/13 = 36
B = 36m
L = 10B/3
L = 10 X 36/3
L = 10 X 12 = 120m
L = 120m
Hence if your were asked to find the area
L X B
120 X 36 = 4320m²

What is $158,035.41 rounded to the nearest 10 dollars?
Answer:
$158,035.41 rounded to the nearest 10 dollars is $158,040
Step-by-step explanation:
Look to the next smallest place value, the digit to the right of the place value you're rounding to. For example, if you want to round to the nearest ten you'd look at the ones place. If the digit in the next smallest place value is less than five (0, 1, 2, 3, or 4), you leave the digit you want to round to as-is.

the scale drawing of a rectangular room measures 10 cm long by 6 cm wide. the actual width of the room is 15 feet. what is the actual perimeter of the room, in feet?
Answer:
80 feet
Step-by-step explanation:
6 cm = 15 feet
1 cm = 5/2 feet
32 cm = 90 feet
The actual perimeter of the room is 90 feet.
What is a scale factor?A scale factor is defined as the ratio between the scale of a given original object and a new object,
We have,
The scale drawing of a rectangular room measures 10 cm long by 6 cm wide.
The actual width of the room is 15 feet.
This means,
6cm = 15 feet
1 cm = 15/6 feet
1 cm = 5/2 feet
Now,
The perimeter of the rectangular room.
= 2(10 + 6)
= 2 x 16
= 32 cm
1 cm = 5/2 feet
So,
32 cm = 32 x 5/2 feet
32 cm = 16 x 5 feet
32 cm = 90 feet
Thus,
The actual perimeter of the room is 90 feet.

If a baby weighs 7 lbs at birth and 12 Ibs after 20 weeks, how much did the baby weigh after 4 weeks, assuming linear growth? [?] lbs
Answer: 8lbs
Step-by-step explanation:
The baby gained one pound
Assuming linear growth, the baby would weigh approximately 8 lbs after 4 weeks.
How to determine the weight of the babyAssuming linear growth, we can use the concept of a slope to estimate the baby's weight after 4 weeks.
Given information:
Weight at birth (0 weeks): 7 lbs
Weight after 20 weeks: 12 lbs
We can calculate the rate of change (slope) of the baby's weight per week:
Slope = (Change in weight) / (Change in weeks)
Slope = (12 lbs - 7 lbs) / (20 weeks - 0 weeks)
Slope = 5 lbs / 20 weeks
Slope = 0.25 lbs/week
Now, using the slope, we can estimate the baby's weight after 4 weeks:
Estimated weight change = Slope * Number of weeks
Estimated weight change = 0.25 lbs/week * 4 weeks
Estimated weight change = 1 lb
So, the baby's weight after 4 weeks would be the initial weight (7 lbs) plus the estimated weight change (1 lb):
Estimated weight after 4 weeks = Initial weight + Estimated weight change
Estimated weight after 4 weeks = 7 lbs + 1 lb
Estimated weight after 4 weeks = 8 lbs
