Answer:
Rate for 100 miles = $ 6 / miles
Rate for 250 miles = $ 3.3 / miles
Step-by-step explanation:
Given that cost for covering 100 miles by flight is $600.
As rate is the cost of covering unit distance (in miles).
So, the rate to cover 100 miles by flight = $ 600/ 100 miles = $ 6 /miles.
Similarly, the cost of covering 250 miles by flight is $825.
So, the rate to cover 250 miles by flight = $ 825/ 250 miles = $ 3.3 /miles.

A building casts a shadow 100 m long. At the same time, a nearby pole 4 m high casts a shadow 8 m long. What is the height of the building? Round your answer to the nearest tenth, if necessary.
Answer:
50m
Step-by-step explanation:
Calculation for the height of the building
First step:
Let x represent the building height
Second step:
100m/8m = x/4
Third step is to Cross multiply:
100m(4) = 8x
400m= 8x
x=400m/8
x=50m
Therefore the height of the building will be 50m

Which of the following tables represents a proportional relationship?
Answer:
C
Step-by-step explanation:
A is incorrect because as x goes from 0 to 1, y jumped from 0 to 4
B is incorrect because as x goes up by 2, y at first goes up by 2 but then jumped to 4.
C is correct because as x goes up by 1, y goes up by 3
D is incorrect because y jumped from 0 to 10 and first but lowered to 5 after.

Step-by-step explanation:• When working with variables and numbers, you have to put the variables first (in alphabetical order) and then the numbers.
• To evaluate an algebraic expression, we find the value of the expression when the variable is replaced by a given number.
• To evaluate an expression, we substitute the given number for the variable in the expression and then simplify the expression using the order of operations.
• When we are not given a number for the variable in the expression, we have to group like-terms.
Example: 5x + 6 + 3x - 2 - y1st: group 5x and 3x (add the terms together) = 8x2nd: group 6 and -2 (add the terms together) = 43rd: Since -y has no like-terms, we can't group it = -yFourth, put the terms in order (variables = alphabetical order and then numbers) = 8x - y + 41. 4x + 12 - 3x + 8
4x - 3x = 1x = x12 + 8 = 20x + 202. -8x + 1 + 2x - 1 + 6x
-8x + 2x + 6x = -8x + 8x = 01 - 1 = 003. 4x - 3 - 2x - 5
4x - 2x = 2x-3 - 5 = -82x - 84. 100x + 5 - 5x + 5
100x - 5x = 95x5 + 5 = 1095x + 105. -4x - 4 - 2 - 5x
-4x - 5x = -9x-4 - 2 = -6-9x - 66. 2x - 1 + 2x - 4 + y
2x + 2x = 4x-1 - 4 = -54x + y - 57. 5y - x + 2y - y + 5
5y + 2y - y = 5y + 1y = 6y-x + 6y + 58. -15 + 3y - 3x - 2y + 4x
3y - 2y = 1y = y-3x + 4x = 1x = xx + y - 159. 4 - 3y + 3x - 2x - y
-3y - y = 4y3x - 2x = 1x = xx + 4y + 4Hope I helped you, if I did can you please mark me the Brainliest?

Chirstine baked a pumpkin pie. She ate 1/6 of the pie. Her brother ate 1/3 f it ang gave leftovers to his friends. What fraction of the pie did he give to his freinds?
Answer:
1/2
Step-by-step explanation:
Let the total pie be 2
She ate 1/6
Her brother ate 1/3
If she gave her Friend the remaining, the fraction of the amount her friend collected is expressed as:
1-(1/6+1/3)
= 1-((1+2)/6)
= 1-3/6
= 1 - 1/2
=1/2
Hence the fraction she gave her friend is 1/2

Can someone substitute this? Please and thank you
Step-by-step explanation:
soln
given
y=2x+3 -----(i)
y=-x-9 ------(ii)
now, putting value of equation (i) in (ii)
y= -x-9
or, 2x+3 = -x-9
or, 2x+x = 9-3
or, 3x = 6
or, x = 6/3
or, x = 2
again,
y = 2x+3
or, y = 2×2+3
or, y = 7
therefore, value of X and Y are 2 and 7 respectively.
solve 3(6b-1)-7(2b+3)=0
Answer:
24/13 or 1.8
Step-by-step explanation:
27b -3 - 14b -21 = 0
13b - 24 = 0
13b = 24
b = 24/13 or 1.8
Answer:
B = 6
Step-by-step explanation
1. (Do the parentheses) 3(6b-1)-7(2b+3) = 18b-3-14b-21
2. (Simplify) 18b-3-14b-21 = 4b-24
3. (Add 24 to both sides) 4b-24+24=0+24
4. (Simplify) 4b = 24
5. (Divide by 4) b = 6
I got some money for my birthday. I save and spend in the ratio 2:3. I save £32. How much money did I receive for my birthday?
Answer:
80 i think
Step-by-step explanation:
32.3=80
Step-by-step explanation:
Amount of money saved : spent = 2 : 3.
Since amount of money saved = £32,
Amount of money spent = £32 * (3/2) = £48.
Total amount of money = £32 + £48 = £80.
Therefore I received £80 for my birthday.

Which expression is equivalent to 2d^2-6/d^2+2d-48 / d-3/2d+16if no denominator equals zero?
Please help. On Pluto
Answer:
B; 4/d-6
Step-by-step explanation:
We want to perform a division here
Flipping the right hand side while changing the sign to multiplication, we have that;
(2d - 6)/ (d^2 + 2d -48) * (2d + 16)/d-3
= 2(d-3)/(d^2 + 2d - 48) * 2d + 16/d-3
= 2/(d^2 + 2d - 48) * 2d + 16/1
2/(d-6)(d + 8) * 2(d + 8)/1
= 2/d-6 * 2/1
= 4/d-6

Answer:
[tex]\bold{m=-\dfrac92=-4.5}[/tex]
Step-by-step explanation:
[tex]\bold{slope\, (m)=\dfrac{change\ in\ Y}{change\ in\ X}=\dfrac{y_2-y_1}{x_2-x_1}}[/tex]
(2, -9) ⇒ x₁ = 2, y₁ = -9
(-2, 9) ⇒ x₂ = -2, y₂ = 9
So the slope:
