The Charles River in Massachusetts is 130 km long.
How long will it be on a map drawn at the scale 1:2,000,000?
Answer: 6.5 cm
Step-by-step explanation: 1 km = 100,000 cm, so 130 km= 130,000,00 cm, 130,000,00÷2,000,000=6.5 cm
The Charles river will be "6.5 cm" long. A complete solution is provided below.
On the map,
→ 1 : 2,000,000
As we know,
The conversion of kilometer in to centimeter is:
→ [tex]1 \ km = 100,000 \ cm[/tex]
then,
→ [tex]130 \ km= 130,000,00 \ cm[/tex]
hence,
The river will be:
= [tex]\frac{130,000,00}{2,000,000}[/tex]
= [tex]6.5 \ cm[/tex]
Thus the above answer is the appropriate.

Please help!!! How many pages can be read in 45 minutes? Answer with a decimal point rounded to the nearest tenth if necessary.
Answer:
157.5 pages
Step-by-step explanation:
First, find your rate. You want to know how many pages you can read per minute. We can use any nuber, but using 2 minutes will be the simplest solution:
2m = 7
--- --- <---- Here we divide both sides of the equal sign by 2
2 2
m = 3.5 <---- we read 3.5 pages per minute
45 x 3.5 = 157.5 (We multiplied 45 because it's the number of minutes we have, by the 3.5 pages we read each minute. This gives us our total of 157.5 pages in 45 minutes.

Answer:
The answer is 36.87°Step-by-step explanation:
Since it's a right angled triangle we can use trigonometric ratios to find the value of B
To find the value of B we use cosine
That's
cos∅ = adjacent / hypotenuse
From the question
adjacent = 4
hypotenuse = 5
We have
[tex] \cos(B) = \frac{4}{5} \\ B = { \cos }^{ - 1} ( \frac{4}{5}) \\ = 36.869897645...[/tex]

Find the missing value so that the line passing through the points has the given slope
(10,y) and (3,4) m= -2/7
Answer:
y = 2Step-by-step explanation:
Using slope formula and solving for y
m = (y2 - y1)/(x2 - x1)
-2/7 = (4 - y)/(3 - 10)-2/7 = (4 - y)/-72 = 4 - yy = 4 - 2y = 2Answer:
y = 2
Step-by-step explanation:
Using slope formula and solving for y
m = (y2 - y1)/(x2 - x1)
-2/7 = (4 - y)/(3 - 10)
-2/7 = (4 - y)/-7
2 = 4 - y
y = 4 - 2

bentonville high school’s student council is planning a fundraiser. a local coffee shop has agreed to make a flag donation of $500 and also give a percent of their total sales over a specified weekend. the total donation can be modeled by the function rule D(s)=500+0.05s, where s represents the total sales at the coffee shop during the fundraising weekend in dollars. find the value of D(2750), showing your work. What does this quantity mean in the context of the problem solution
Answer: D(2750) = 637.5
if total sales = $2750 then total donation = $637.5
Step-by-step explanation:
GIven: A local coffee shop has made a flat donation of $500 and also give a percent of their total sales over a specified weekend.
The total donation can be modeled by the function rule D(s)=500+0.05s,
where s = total sales at the coffee shop during the fundraising weekend in dollars.
Now, D(2750) = 500+0.05(2750)
= 500+ 137.5
= 637.5
i.e. if total sales = $2750 then total donation = $637.5

The sum of one and three fifths of a number is at most 42.(i need help with this)
Answer:
Step-by-step explanation:
Let x=smaller number
Then x+5=larger number
Now we are told the following:
1/5(x+x+5)=x-5 multiply each side by 5
x+x+5=5x-25 subtract 5x and also 5 from both sides
x+x+5-5-5x=5x-5x-25-5 collect like terms
-3x=-30 divide both sides by -3
x=10-----------------------smaller number
x+5=10+5=15 ---------larger number

plz use the image below
Part (i)
Answer: m/n
--------------------
Explanation:
You divide the total bill over the number of people at the dinner. This leads to the quotient and the amount each person pays (each person pays the same amount).
====================================================
Part (ii)
Answer: 80 dollars
--------------------
Explanation:
Plug in m = 400 and n = 5 to get
m/n = 400/5 = 80
====================================================
Part (iii)
Answer: m = 7x
--------------------
Explanation:
x = m/n
x = m/7
7x = m ... multiply both sides by 7
m = 7x
The total bill is 7 times of what each person paid.
====================================================
Part (iv)
Answer: 7 people
--------------------
Explanation:
x = 20 is the amount each person paid
m = 140 is the total bill
n = number of people who went to dinner
x = m/n
20 = 140/n
20n = 140 ..... multiply both sides by n
n = 140/20 ..... divide both sides by 20
n = 7
Seven friends went to do dinner, splitting a $140 bill, paying $20 each
Answer:
m/n; $80; 7*x; 7 friends
Step-by-step explanation:
(I) $x=$m/n
(II) $x=400/5=$80
(III) $m=7*x
(IV) n=140/20=7

Given parameters:
Length of the gift box = 8 inches
Width of the box = 3 inches
Height of the box = 4 inches
Unknown :
Length of its longest diagonal = ?
Solution:
This is a rectangular box.
To find the diagonal of such box, let us use the formula below;
Diagonal = [tex]\sqrt{l^{2} + w^{2} + h^{2} }[/tex]
l is the length
w is the width
h is the height
Input the parameters and solve;
Diagonal = [tex]\sqrt{8^{2} + 3^{2} + 4^{2} }[/tex] = 9.4inches
The diagonal of the box is 9.4inches

An inchworm is crawling up a tree. It begins 18 inches above the ground and climbs up 3 inches every minute. Let t represent the number of minutes since the worm began climbing. Veronica wants to know when the inchworm will be more than 60 inches above the ground. Which inequality should she use?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Starting point = 18 inches
Rate or speed = 3 inch per minute
t = number of minutes since climbing began
When will worm be more than 60 inches above the ground.
Height (t) = starting point + (rate * time)
18 + 3t > 60
3t > 60 - 18
3t > 42
t > 42/3
t > 14
Hence, inequality to use is : 60 > 18 + 3t
