on a map the scale shown is 1 inch = 5 miles if a park is 75 square miles what is the area of the park on the map
Answer:
75 miles squared
Step-by-step explanation:
First we have to convert 1 inch = 5 miles to square miles as that is what we are trying to get
So, 1 inch squared = 25 miles squared
To get 75 miles squared, we multiply both sides by 3.
So 3 * 1 inch squared = 3 * 25 miles squared
Gets us 3 inch squared = 75 miles squared
Make M the subject of the expression T = WP [ M² - ( M-S)² ]
Answer:
see below (I hope this helps!)
Step-by-step explanation:
T = WP [ M² - (M - S)² ]
T = WP [ M² - (M² - 2MS + S²) ]
T = WP (2MS - S²)
T = 2WPMS - WPS²
T + WPS² = 2WPMS
M = (T + WPS²) / (2WPS)
The length of a rectangle is 6 meters less than twice its width. If the area of the rectangle is 308 m2, what are its dimensions?
Answer:
length = 22cmwidth = 14cmStep-by-step explanation:
Area of a rectangle = l × w
where
l is the length
w is the width
From the question
Area = 308 m²
The length of a rectangle is 6 meters less than twice its width is written as
l = 2w - 6
Substitute this into the above formula and solve for the width
We have
308 = (2w - 6)w
2w² - 6w = 308
2w² - 6w - 308 = 0
Divide both sides by 2
We have
w² - 3w - 154 = 0
( w + 11)( w - 14) = 0
w + 11 = 0 w - 14 = 0
w = - 11 w = 14
Since the width cannot be negative
w = 14
Substitute w = 14 into l = 2w - 6
That's
l = 14(2) - 6
l = 28 - 6
l = 22
Therefore
length = 22cm
width = 14cm

Mrs. Grundy has two children. Given that Mrs. Grundy has at least one child born on a Monday, what is the probability that both her children were born on Mondays? Assume that each child was equally likely to be born on any day of the week, and that the two birthdays are independent (Mrs. Grundy doesn't have twins!).
Answer:
1/7
Step-by-step explanation:
If one child was born on a Monday, then we don't have to consider that when solving the question, as it asks if both children were born on a Monday.
Thus, we only need to find the probability that the second child is born on a Monday. Since there are 7 days in a week and equally likely that the child is born on any day, then the probability of the child being born on a Monday would be 1/7.

A circular go-kart track has a diameter of 75 meters. Approximately how long is the track? A225 meters B100 meters C750 meters D500 meters
Answer:
235 metersStep-by-step explanation:
This problem is on the mensuration of flat shapes, a circular shape.
the problem also requires that we find the perimeter of the circular track
the expression for the perimeter of a circle is given as
[tex]C= 2\pi r[/tex]
Given
diameter of the circular track = 75 meters
radius of circular track = d/2 = 75/2= 37.5 meters

2(4x-6) = 4(3x-7) what is x
Answer:
The value of x in this equation is -4.
Step-by-step explanation:
2(4x - 6) = 4(3x - 7)
Distribute 2 to (4x - 6) and distribute 4 to (3x - 7)
8x - 12 = 12x - 28
Subtract 12x form both sides of the equation.
-4x - 12 = -28
Add 12 to both sides of equation.
-4x = 16
Divide -4 on both sides of the equation.
x = -4
The value of x is -4.
Answer:
x=4
Step-by-step explanation:
Starting with 2(4x-6) you apply the distributive law: a(b-c) = ab - ac
a =2, b=4x, c=6
2(4x-6) = 2*4x-2*6 Then multiply the numbers 2*4
8x-2*6 = multiply 2*6
8x-12
Then for 4(3x-7) you apply the distributive law.
a =4, b=3x, c=7
4*3x-4*7 multiply 4*3
12x-4*7 multiply 4*7
12x-28
Then the equation would be 8x-12 = 12x-28. Add 12 to both sides.
8x=12x-16 Subtract 12x to both sides
-4x=-16 divide both sides by -4
then you'll get Positive 4 as your x.
help..help..!! ASAP..
so you divide the rational number if the decimal on both sides if one is greater and the other less than the number that's greater should have the greater sign. but, if theres a number that's less then you should put the less than sign and if both numbers are the same number you should put the equal sign
Please help me with question
Answer:
4 hours 7 minutes
Step-by-step explanation:
Since Trevon takes 10 hours to clean the attic, he cleans 1/10, 10% or .1 of the attic per hour. Since Cody takes 7 hours to clean the attic, he cleans 1/7, 14.3% or .143 of the attic per hour.
Together, that means they clean .1 + .143 of the attic per hour. That's an hourly rate of:
.1 + .143 = .243
The portion of the attic they clean in x hours is .243x. We'd like to know how long it will take them to clean 100% or 1 of the attic. So:
.243x = 1 Divide each side by .243
x = 1/.243
x ≈ 4.115
Let's convert .115 to minutes by multiplying by 60
.115 * 60 = 6.9 round to 7 for 7 minutes
It will take them around 4 hours 7 minutes to clean the attic.

HELP PLEASE The value of a stock can be modeled by this equation. V = 23n + 42; where V is the value, in dollars, and n represents the number of months since purchase. Which statements correctly interpret the slope of the line? A. The slope of the line is 42. This means that the value of the stock increases $42 for each additional month since purchase. B. The slope of the line is 42. This means that the initial value of the stock was $42. C. The slope of the line is 23. This means that the initial value of the stock was $23. D. The slope of the line is 23. This means that the value of the stock increases $23 for each additional month since purchase.
Answer:
D. The slope of the line is 23. This means that the value of the stock increases $23 for each additional month since purchase.
Step-by-step explanation:
In the basic equation y = mx + b, m is the slope. In this situation, 23 is the slope because it is the coefficient.
42 is not the slope because it is the y-intercept.
D is the correct answer because the slope is 23, which means in this situation that the stock's value increases by $23 for each additional month after the purchase.
Answer:
D.
Step-by-step explanation:
The slope is the coefficient of n ( the month) which is 23.
This means the stock increases each month by a factor of 23.
Multiply the trinomials.

for each diagram, determine whether angles 1 & 2 form a linear pair, heeelp please :(
Answer:
only (12) has a linear pair
Step-by-step explanation:
Recall that for two angles to be called a "Linear Pair", they need to satisfy several conditions:
1) The two lines must intersect at a shared point (i.e common vertex)
2) The two angles must be adjacent (i.e immediately next to one another)
3) The two angles must add up to 180 degrees.
In our case,
in (9), the angles are not adjacent and they do not add up to 180 deg, so this is NOT a linear pair
in (10), the angles are not adjacent and they do not add up to 180 deg, so this is NOT a linear pair
in (11), the lines do not intersect at a shared point(they do not have a common vertex). Plus we cannot be 100% sure that they add up to 180 deg. Hence this is not a linear pari
in (12), we can see that the angles satisfy all 3 conditions above. This is a linear pair.

Full question :
A man buys a certain number of oranges at 20 for Rs. 60 and an equal number at 30 for Rs. 60. He mixes them and sells them at 25 for Rs. 60. What is the gain or loss percent?
Answer:
4% loss(percentage loss on cost price)
Step-by-step explanation:
we will be employing algebra in solving this problem :
20 oranges at 60 Rs=60Rs/20 per orange=3Rs per orange
Say x oranges bought at 3Rs per orange=3Rsx
Equal number of oranges at 30 oranges for 60 Rs=60Rs/30 per orange=2Rs per orange
Say x oranges bought at 3Rs per orange=2Rsx
Total Cost Price = 3Rsx + 2Rsx = 5Rsx
He then sells all oranges at 25 for 60 Rs
Therefore price per orange=60/25=12/5Rs
since he sold x+x oranges(from the above calculations)
Total selling price=total oranges *12/5Rs=2x oranges*12/5Rs=24x/5Rs
Profit or loss=24x/5-5x=-x/5
therefore we have a loss =-x/5
Percentage of loss(on cost price)
=x/5÷5x∗100=
=1/25∗100=4%
hydrogen and oxygen come pouring out it drips and it dribbles and it comes from a spout
Answer:
[tex]\Large \boxed{\mathrm{Water}}[/tex]
Step-by-step explanation:
Hydrogen and oxygen are elements that form the compound known as water.
Water comes pouring out, it drips, it dribbles, and it comes from a spout.
Answer:
Water
Step-by-step explanation:
Most of the water in our world is a combination of "ordinary" hydrogen atoms with "ordinary" oxygen atoms, but there are actually three different istopes (atomic varieties) of hydrogen and each of those can combine with oxygen to give a different kind of water.
If deuterium (hydrogen whose atoms contain one neutron and one proton instead of just one proton by itself) combines with oxygen, we get something called heavy water, which is about 10% heavier than normal water.
Similarly, tritium (hydrogen with two neutrons and one proton) can combine with oxygen to make something called super heavy water.
Water comes pouring out it drips and it dribbles and it comes from a spout.
