Answer:
420m
Step-by-step explanation:
250m = 5cm
50m = 1cm
? = 8.4cm
50 x 8.4=
420m = 8.4cm
Step-by-step explanation:
firstly we need to find the scale factor
firstly we know that 250m=25000cm
25000/5=5000
so 1:5000 is scale factor.
Now let us find the distance between Sam's school and the library
if they are 8.4 cm apart on map it means that in actual distance they are
(8.4)*5000=42000 cm in reality

April is going to the bakery to purchase donuts and cinnamon rolls for the office personnel. She must purchase at least 30 items. She has collected only $30, so total cost must be no more than $30. If d represents donuts that cost $0.75 each and r represents cinnamon rolls that cost $1.25 each, which system of inequalities can be used to represent the region for the number of donuts and cinnamon rolls April could purchase?
A.d + r ≥ 30
0.75d + 1.25r ≤ 30
B. d + r ≥ 30
1.25d + 0.75r ≤ 30
C. d + r ≤ 30
0.75d + 1.25r ≥ 30
D. d + r ≤ 30
1.25d + 0.75r ≥ 30
Please answer quickly :)
The system of inequalities that can be used to represent the region for the number of donuts and cinnamon rolls April could purchase is $0.75d + $1.25r ≤ $30
April cannot spend more than $30. Thus, the inequality sign that would be used is ≤ (the less than or equal to sign).
April wants to purchases two items, cinnamon rolls and donuts. The donuts cost $0.75 per dollar and cinnamon rolls cost $1.25 per dollar.
The total amount April can spend on donuts = $0.75 x d = $0.75d
The total amount April can spend on cinnamon rolls = $1.25 x r = $1.25r
The sum of $0.75d and $1.25r has to be less than $30
This can be represented with this inequality: $0.75d + $1.25r ≤ $30

PLEASE HELP!! Find the market equilibrium point for the following demand and supply equations
9514 1404 393
Answer:
(p, q) = (16, 20)
Step-by-step explanation:
You can add the two equations together to make one from which q can be eliminated:
(4p) +(3p -q) = (-q +84) +(28)
7p -q = -q +112 . . . . simplify
7p = 112 . . . . . . . . . . add q
p = 112/7 = 16
Using this value in the second equation, we get ...
3·16 -q = 28
48 -28 = q = 20 . . . . . add q-28
The equilibrium point is (p, q) = (16, 20).
You are given space that limit as h rightwards arrow 0 of fraction numerator g (3 + h) - g (3)/h = 7 and g (3) = 9. Find m and b so that the tangent space line of g (x) at x = 3, y = m x +b.
Answer:
m = 7 and b = -12 therefore y = 7x - 12
Step-by-step explanation:
From the question we are given the first derivative of the function g to be 7, and it is known that the first derivative of a function is the slope, therefore the slope, m = 7.
Since we are looking for 'b' at x = 3 and we know that our slope is 7, we have:
g(3) = 7*3 + b. We are given g(3) = 9 so we have:
9 = 21 + b and b = -12.
Therefore, m = 7 and b = -12 and the equation of the line is y = 7x - 12.

The decline of salmon fisheries along the Columbia River in Oregon has caused great concern among commercial and recreational fishermen. The paper 'Feeding of Predaceous Fishes on Out-Migrating Juvenile Salmonids in John Day Reservoir, Columbia River' (Trans. Amer. Fisheries Soc. (1991: 405-420)) gave the accompanying data on
y= maximum size of salmonids consumed by a northern squaw fish (the most abundant salmonid predator) and
x= squawfish length, both in mm.
Use the following statistics to give the equation of the least squares regression line.
x=524.880,
y=413.975,sx=12.251,sy=12.300,
r=0.9562
options:
a) ^y=0.960xâ89.910
b) ^y=0.960x+89.910
c) ^y=â89.910x+0.960
d) ^y=0.952x+89.910
e) ^y=0.952xâ89.910
f) None of the above
Answer:
the correct answer is not there. here it is:
^y = 0.960x - 89.910
Step-by-step explanation:
we have regression line equation as:
^y = a+bx
we have the following details available
x = 524.88
y = 413.975
Sx = 12.251
Sy = 12.300
r = 0.9562
we have to find values of a and b
b = rSy/Sx
= 0.9562(12.3)/12.251
= 11.76126/12.251
= 0.960
a = y - intercept
= 413.975-0.96(524.88)
= 413.975-503.8848
= - 89.9098
a = -89.910
putting these values into the equation, we have:
^y = -89.910 + 0.9600x
which is also
^y = 0.960x - 89.910

A wheel of a child's bicycle has a circumference that is 50% of the circumference of a child's mountain bicycle wheel. The child's bicycle wheel has a circumference of 37.7 inches. a. What is the radius (to the nearest inch) of the child's bicycle wheel? of the child's mountain bicycle wheel? b. The child's mountain bicycle wheel takes 2 seconds to make 3 revolutions . How fast(to the nearest inch per second) is the bicycle moving?
Answer:
36960in per minute
Step-by-step explanation:
Answer:
a) 6 inchesb) 113 inches per secondStep-by-step explanation:
Let the child bicycle wheel radius be x
Then its circumference is
C = 2πxa) Solving for x
37.7 = 2*3.14xx = 37.7/6.28x = 6.0 inb) Mountain bicycle has twice the circumference of a child bicycle
In 2 seconds it makes 3 revolutions
It makes the distance of
d = 3*2*37.7 = 226.2 inches in t = 2 secondsSpeed = d/t
Speed is:
226.2/2 = 113 inches/second
