Answer:
x = 24
Step-by-step explanation:
Complete question
Y and x have a proportional relationship, and y = 24 when x = 16 What is the value of x when y = 36?
If y is proportional to x, then;
y = kx
24 = 16k
k = 24/16
k = 1.5
Recall that y = kx
36 = 1.5x
x = 36/1.5
x = 24
Hence the required value of x is 24

An event management company purchases a new van. The value of the van, x years after the purchase, is shown in the table.
Time (years) 0 1 2 3
Value (dollars) 20,000 18,000 16,200 14,580
Which statement is true?
A.
The situation can be modeled by an exponential decay function with a percent change of -10%.
B.
The situation can be modeled by an exponential growth function with a percent change of 11%.
C.
The situation can be modeled by an exponential decay function with a percent change of -11%.
D.
The situation can be modeled by an exponential growth function with a percent change of 10%.
The situation can be modeled by an exponential decay function with a percent change of -10%, option A is correct.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
The ratio between the value after 1 year and the value after 0 years is 18,000/20,000 = 0.9.
The ratio between the value after 2 years and the value after 1 year is 16,200/18,000 = 0.9.
The ratio between the value after 3 years and the value after 2 years is 14,580/16,200 = 0.9.
Since the ratio between consecutive values is constant and less than 1, we can conclude that the situation can be modeled by an exponential decay function.
r = (18,000/20,000) - 1 = -0.1
So the percent change per year is -10%, which means that statement A is true.
Hence, the situation can be modeled by an exponential decay function with a percent change of -10%, option A is correct.

Volume without holes = 3 x 6 x 11 = 198 cubic inches.
Calculate volume of one hole:
3.14 x 0.5^2 x 3 = 2.355 cubic inches
There are 3 holes: 3 x 2.355 = 7.065
Subtract volume of the holes from the brick:
198 - 7.065 = 190.935 cubic inches.
Rounded to the nearest tenth: 190.9 cubic inches.
Answer:
190.9 inches^3
Step-by-step explanation:
First of all we have to find the total volume:
V = dimension 1 x dimension 2 x dimension 3
V = 3 x 6 x 11 = 198 inches^3
now we have to find the volume of the cylinders:
V= radius^2 x pi x height = 0.5^2 x 3.14 x 3 = 2.355 inches^3
the cylinders are three so:
V = 2.355 x 3 = 7.065 inches^3
at least we have to subtract this value at the total volume:
V= 198 - 7.065 = 190.935 = 190.9 inches^3

Answer:
more than half are being used
Step-by-step explanation:
Perhaps easiest to understand is the most straightforward: figure the total number of seats and the number of seats being used. Check to see if that is more than half.
The 1 first-class carriage has usage of ...
(3/8)(64 seats) = 24 seats.
The 6 standard carriages have usage of ...
(7/13)(6 · 78 seats) = 252 seats.
The total number of seats used is ...
24 + 252 = 276 . . . . seats used
__
The total number of seats on the train is ...
1·64 +6·78 = 532 . . . . seats on the train
Half of the seats on the train will be ...
532/2 = 266 seats . . . . half the seats
The 276 used seats are more than half of the total number. More than half the seats are being used.
_____
Alternate solution
Another way to look at this is to compare utilization to 1/2 in each carriage class.
In first class 1/2 -3/8 = 1/8 of 64 seats = 8 seats fewer than 1/2 the seats are being used.
In standard class, 7/13 -1/2 = 14/26 -13/26 = 1/26 of 78 seats = 3 seats more than 1/2 the seats are being used. There are 6 standard class carriages, so 6·3 = 18 more than half the seats in the standard-class carriages are being used.
This number is 10 more than the 8 under-utilized seats in first class, so more than half the train seats are being used.

Answer:
it would be (10)- (4)
Step-by-step explanation:
The expression for the volume of the shaded part of the sphere is (4/3)π(10)³, or 4,188.7902 cubic feet.
What is diameter?Diameter is a straight line passing through the centre of a circle or other safe, or the length of first as millimetre centimetre inches and feet.
here, we have,
The expression that represents the volume of the shaded part of the sphere is (4/3)πr³,
where r is the radius of the sphere,
which is 10 feet (1/2 the diameter).
Therefore, the expression for the volume of the shaded part of the sphere is
(4/3)π(10)³,
or 4,188.7902 cubic feet.
Hence, The expression for the volume of the shaded part of the sphere is (4/3)π(10)³, or 4,188.7902 cubic feet.

Solve the system of equations using subtraction. 2x-4y= -12 2x+y=8 plz help
Answer:
x=2, y= 4
Step-by-step explanation:
Equation 1 is 2x-4y = -12
Equation 2 is 2x+y = 8
Subtracting the two equations gives -4y-y = -12-8 (The 2x and the other 2x cancel each other out).
Simplifying we get -5y = -20 and y =4
Substituting y =4 into original equation back we get 2x -4(4) =-12
This equals 2x -16 =-12 and 2x = 4 and x =2

Rob is on vacation in Paris, France. When Rob visited the Eiffel Tower today, he climbed 1,000 stairs in 25 minutes. Tomorrow, Rob will climb 280 stairs at Montmartre. If he climbs at the same rate, how many minutes will it take Rob to climb the stairs tomorrow?
Answer:
7 minutes
Step-by-step explanation:
The computation of the number of minutes that climbs the stairs tomorrow is shown below:
Given that
He claimed 1000 stairs in 25 minutes
So for 280 stairs, he would take
= 280 × 25 minutes ÷ 1000 minutes
= 7000 ÷ 1000
= 7 minutes
hence, 7 minutes would be taken
