Step-by-step explanation:
New York City has a population of 8.55 million and 300 square mile. Manhattan has 1.64 million and 23 square miles. How much greater is the population of Manhattan than New York City?
Given :
New York City has a population of 8.55 million and 300 square mile area .
Manhattan has 1.64 million and 23 square miles area .
To Find :
How much greater is the population density of Manhattan than New York City.
Solution :
Population density of New York City :
[tex]D_{NY}=\dfrac{8.55}{300}=0.029 \ million/mile^2\\\\D_{M}=\dfrac{1.64}{23}=0.071 \ million/mile^2[/tex]
Now ,
[tex]D_{M}-D_{NY}\\\\(0.071-0.029)=0.042\ million/miles^2[/tex]
Therefore , population density of Manhattan is [tex]0.042\ million/miles^2[/tex] greater than New York City .
Hence , this is the required solution .

Answer:
8h + 15 = 39
Step-by-step explanation:
The base fee is 15 so you shouldn't multiply the hours by it.
The question states 8 per hour which means that you should multiply the 8 by hours and add on the base fee which is 15.
Answer:
8h+15=39

Solve the following system of equations using the elimination method. 2x + 4y = 10 –2x + y = –15
Answer:
(7, - 1 )
Step-by-step explanation:
Given the 2 equations
2x + 4y = 10 → (1)
- 2x + y = - 15 → (2)
Adding the 2 equations term by term eliminates the term in x, that is
5y = - 5 ( divide both sides by 5 )
y = - 1
Substitute y = - 1 into either of the 2 equations and solve for x
Substituting into (1)
2x + 4(- 1) = 10
2x - 4 = 10 ( add 4 to both sides )
2x = 14 ( divide both sides by 2 )
x = 7
Solution is (7, - 1 )
(7, - 1 )
Step-by-step explanation:
Given the 2 equations
2x + 4y = 10 → (1)
- 2x + y = - 15 → (2)
Adding the 2 equations term by term eliminates the term in x, that is
5y = - 5 ( divide both sides by 5 )
y = - 1
Substitute y = - 1 into either of the 2 equations and solve for x
Substituting into (1)
2x + 4(- 1) = 10
2x - 4 = 10 ( add 4 to both sides )
2x = 14 ( divide both sides by 2 )
x = 7
Solution is (7, - 1 )

In triangle ABC, the measure of angle B is 50 degrees. Give possible values for the measures of angles A and C if ABC was an acute triangle.
Answer:
Step-by-step explanation:
An acute triangle is a triangle that has all the measures of its angles to be less than 90° i.e none of the angles is greater than 90°
Since of angles in a triangle is 180, hence <A + <B + <C = 180
Given
<B = 50
50 + <A + <C = 180°
<A + <C = 180-50
<A + <C = 130°
Note that all the angles of an acute triangle are also different
Hence the possible values of A and C are 60° and 70° (since their sum must give is 130°)
Another possible values are 55° and 75°
60° and 70°
55° and 75°

(2+1) - 4 x 5 + 31
Answer:
14
Step-by-step explanation:
Here's where you'll use the infamous PEMDAS, which just means how to solve the equation in order.
P means parentheses
E means exponents
M means multiplication
D means division
A means addition
S means subtraction
So start with P. Here we have (2+1) so that becomes 3. Which then turns the equation into: 3 - 4 × 5 + 31. Next Is E but since there are no exponents here you skip that step. Next is M. You have 4 × 5 which is 20 so the equation then becomes: 3 - 20 + 31. Next is D but since there's nothing to divide you can skip that too. You can actually go right ahead and solve it here because in PEMDAS you can actually just do all MD problems together from left to right, same as and AS problems in order from left to right, instead of doing M and then D or A and then S.

3(a - 1) + 2a = a + 1
Answer:
a = 1
Step-by-step explanation:
Step 1: Write equation
3(a - 1) + 2a = a + 1
Step 2: Solve for a
Distribute 3: 3a - 3 + 2a = a + 1
Combine like terms: 5a - 3 = a + 1
Subtract a on both sides: 4a - 3 = 1
Add 3 on both sides: 4a = 4
Divide both sides by 4: a = 1
Frank needs to fill juice cups for his sis there r 35 cups amd it holds 12 fluid ounces. The juice came in a 1 gallon bottle how many 1 gallon bottles of juice will he need to purchase?
Answer:
4 gallons
Step-by-step explanation:
He needs 105 over 3 to fill all the cups. 1 gallon would be 10 and 2 third cups or 32 over 3. 2 gallons would be 21 and 1 third cups or 64 over 3. 3 gallons would be 32 or 96 over 3. 4 gallons would be 42 and 2 third cups or 128 over 3. So 4 gallons would fill up all 35 of his sisters 12 ounces cups. That would leave 7 and 2 third cups that hold the same amount. His sister gets all 35 of her 12 ounces each cups filled and he gets 7 and 2 thirds of new and unused 12 ounces cups. Basically out of the 4 gallons there would be 512 ounces and his sister with all 35 cups that hold 12 ounces each she would get 420 ounces. Which would leave him with 92 ounces of juice for himself. Hope this understandable and helpful.
If T is the midpoint of SU, what are ST, TU, and SU.
*Question 16*
We have ST=5x, TU=3x+32 and they're equal if T is the midpoint:
5x = 3x + 32
2x = 32
x = 16
ST = 5x = 80
So TU = 80 and SU=160

Janel can make total of 12 bracelets.
DivisionWhat is division?One of the four fundamental operations, along with addition, subtraction, and multiplication, is division. A number is split in the straightforward action of division.
Relation of dividend, divisor, quotient and remainder:The following dividend formula can be used to find the dividend if the values of the divisor, quotient, and remainder are provided.
Dividend = Divisor x Quotient + Remainder
Calculation for the number of bracelets:Janel has total number of beads = 600.
Beads required to make one bracelet = 48.
To calculate the number of beads divide total number of beads by 48.
Beads = 600/48
Quotient comes out as 12 and remained comes out as 24.
Therefore, the total number of bracelets can made is 12.
After completion of 12 bracelets 24 beads will left.

We have to simplify and get the value of x from this inequality given:
Given inequality,
[tex]3(x - 4) > 5x + 2[/tex]
Now let's simplify by using distributive property,
[tex]3x - 12 > 5x + 2[/tex]
We need to find x, so let's isolate x to the letter side of the inequality for calculation at ease.
[tex]3x - 12 - 5x - 2 > 0[/tex]
[tex] - 2x - 14 > 0[/tex]
Now, dividing -2 from both sides.
Note : As we are dividing a negative number from both sides, the sign of the inequality will be reversed.
[tex] \dfrac{ - 2x - 14}{ - 2} > \dfrac{0}{ - 2} [/tex]
[tex]x + 7 < 0[/tex]
Now subtracting -7 from both sides,
[tex]x + 7 - 7 < 0 - 7[/tex]
[tex]x < - 7[/tex]
