Answer:
Jack needs to run at a speed of 1/12 mph
Step-by-step explanation:
Mathematically;
speed = distance/ time
Distance = speed * time
10 minutes = 10/60 h = 1/6 hours
The distance to the school will be
Distance = 3 * 1/6 = 1/2 = 0.5 miles
Now, he needs to be at school 4 minutes earlier, time will now be 10 - 4 = 6 minutes
To get the speed here;
Recall that the distance from above does not change
So speed = 0.5/6 mph 0r 1/12 mph

10 POINTS PLEASE HELP ASAP!!! What is the length of the altitude of the equilateral triangle below?
Step-by-step explanation:
Hey there!
Looking on figure we find that triangle ABC is a Right angled triangle.
Taking reference angle as C, we get;
Perpendicular (p) = a
Base(b) = 5
And hypotenuse (h)= 10
Now;
Using Pythagoras relation, we get;
[tex]p = \sqrt{ {h}^{2} - {b}^{2} } [/tex]
Put all values.
[tex]a = \sqrt{ {10}^{2} - {5}^{2} } [/tex]
[tex]a = \sqrt{100 - 25} [/tex]
[tex]a = \sqrt{75} [/tex]
[tex]a = 5 \sqrt{3} [/tex]
Therefore, answer is Option E.
Hope it helps..

The sum of the first 44 positive odd numbers is
nothing ______
Answer:
1936
Step-by-step explanation:
The sum of the first n odd numbers is n^2
This can be proven, but for 5 odd numbers, 1,3,5,7,9, the sum should be 5^2, or 25, which it is
So for the first 44 odd numbers, the sum is n^2=44^2=1936
Mr. and Mrs. Wagner are getting ready to drive across the USA from Philadelphia, PA to Los Angeles, CA in five days. The distance is approximately 3,000 miles. The average price of gasoline is about $2.10 per gallon. They plan to stay in a hotel for four nights and budget the cost of meals be about $45 per day per person.
Answer:
(a) $ 84.
Step-by-step explanation:
Given that, the distance between the PA to CA = 3000 miles.
Time of travel, t = 5 days.
The average price of gasoline, r = $ 2.10/ gallon
Cost of meal for one person, c = $ 45/ day
Total number of persons, n = 2 (Mr. and Mrs. Wagner)
(a) The average of van = 75 mpg.
So, to cover 75 miles, the amount of gasoline required = 1 gallon
By using the elementary method, the amount of gasoline required to cover 1 mile = 1/75 gallons.
So, the amount of gasoline required to cover 3000 miles
= (1/75)x 3000= 40 gallons.
Now, cost for gasoline = 40 x 2.10=$84
Hence, the total cost of the gas for the trip is $84.
What is the slope of the line that passes through the
points (-4, 10) and (2, 22).
Answer:
2
Step-by-step explanation:
slope= (y2-y1)/x2-x1)
= (22-10)/(2--4)
= 12/(2+4)
= 12/6
=2
Find the square root of the
following numbers by prime factorisation method :
(iii) 3136
Reduce: -8/40 (pls answer)
Answer:
-1/5
Step-by-step explanation:
The first step you do is to find what are the numbers GCF which in this case it is 8
which now with the GCF you divide -8 by 8 and 40 by 8
which -8 divided by 8 is -1
and 40 divided by 8 is 5
so the fraction is -[tex]\frac{1}{5}[/tex]

How does the side length of the square relate to the square root?
Answer:
The sides can be found by taking the square root of the area. , where = side.
Step-by-step explanation:
Answer:
the area of any quadrilateral can be determined by multiplying the length of its Base by its height. since we know the shape here is square we know that all sides are of equal length. from this we can work backwards by taking the square root of the area to find the length of one side.

hello !
if a line has a slope of 2/3 a line that is perpendicular has a slope of what
Answer: -3/2
Step-by-step explanation:
The slope of this line is 2/3, so the slope of the line perpendicular will have the opposite reciprocal as a slope, which is -3/2.

While on vacation, your family traveled 2660 miles in 7 days. Your average speed was 380 miles per day.
a. Find the independent and the dependent variables.
b. Write a linear function that models the distance that your family traveled each day.
c. Use the model to find the distance traveled after 1.5 days of travel
Answer:
see below
Step-by-step explanation:
a. The independent variable is the speed
The dependent variable is the number of miles traveled because it depends on your speed
b. miles = s *day
miles = 380 * days
c. miles = 380 * 1.5
=570 miles

How to estimate a non-perfect square root to the hundredths place without using a calculator?
Answer:
Approximate between two whole numbers by finding the perfect squares nearest to the target number. Identify which value the non-perfect square root is closest to, then use the iterative process to approximate further to the tenths place, and then further to the hundredths place.

Which of the following tables represents the rule, y equals seven less than four times a number?
Answer:
the second table.
Step-by-step explanation:
I used process of elimination to determine which one fits.
here's how I know I'm correct:the rule is, y = 4x - 7
if you put in the numbers from table 2
-3 = 4(1) - 7
-3 = 4-7
-3 = -3
13 = 4(5) - 7
13 = 20 - 7
13 = 13
Dolbear’s law states the relationship between the rate at which snow a tree crickets chirp and the air temperature of their environment the formula is T = 50+ N - 40 over 4 where T is a temperature in degrees Fahrenheit and N is a number of chirps per minute if N = 66 find the temperature in degrees Fahrenheit. T
Answer:
T=76
Step-by-step explanation:
If the formula is T=50+N-40 and N=66 then you just substitute 66 in for N then you have T=50+66-40 where as T=76
