Answer:
[tex]A : B = 8 : 5[/tex]
Step-by-step explanation:
Given
Truck A
[tex]Distance = 24 miles[/tex]
[tex]Time = 3 hours[/tex]
Truck B
[tex]Distance = 20 miles[/tex]
[tex]Time = 4 hours[/tex]
Required
Determine the ratio of their speeds
Speed is calculated as:
[tex]Speed = \frac{Distance}{Time}[/tex]
For A:
[tex]A= \frac{24}{3}[/tex]
[tex]A = 8[/tex]
For B:
[tex]B = \frac{20}{4}[/tex]
[tex]B = 5[/tex]
So, the ratio is:
[tex]Ratio = A : B[/tex]
[tex]A : B = 8 : 5[/tex]

A meal that cost $50 had a 20% tip and 5% sales tax. How could you calculate your final total bill?
Answer:
$57.50
Step-by-step explanation:
find 10% of 50 first, which is 5, because 5 × 10 = 50, then add $10 to the $50 beacause 50 × 0.2 = 10, next, remove 5%, to do this divide 10% by 2 to get $2.50, 60 - 2.5 = 57.5

Which of the following is a correct method to verify that two functions
are INVERSES of each other?
the graphs of the functions are a reflection across the line y = -x.
the graphs of the functions are a reflections across the y axis.
the graphs of the functions are a reflection across the line, y = x.
O The correct or complete answer is not in any of the choices.
Answer:
C) the graphs of the function are a reflection across the line, y = x
Step-by-step explanation:
Inverse functions have graphs that are reflections over the line y = x and thus have reversed ordered pairs.
HOPE THIS HELPS!!!! <33333
-Silver
When that two functions are INVERSES of each other then
The graphs of the functions are a reflection across the line y = x
Option C
Given :
The two functions that are inverse to each other
When two functions are inverse to each other then
the domain of function f is the range of inverse function
The range of function f is the domain of inverse function
x values of function f = y values of inverse function
y values of function f = x values of inverse function
Hence we can say that the graph of function are reflection across y=x
The graphs of the functions are a reflection across the line y = x

A and B are correct
Step-by-step explanation:
if x:y is 1:3 then x is 1 and y is 3
1/3 of 3 is 1 so A is correct
3/4(1+3) is 3 so B is correct
But
1/4 × 3 is not 1 so C is not correct
3/4 ×1 is not 3 so D isn't correct

a large painting has a length of 18 inches and width of 12 inches. If each dimension is reduced by x inches to make the ratio of length to width 5 to 3, what is the value of x
Answer:
The value of x = 3.
Step-by-step explanation:
The ratio between length and width is given by:
[tex]\frac{L}{W}=\frac{5}{3}[/tex]
Where:
L represents the new length W represents the new widthNow, we know that each dimension is reduced by x inches, it means:
[tex]L=18-x[/tex]
[tex]W=12-x[/tex]
Then, we will have:
[tex]\frac{18-x}{12-x}=\frac{5}{3}[/tex]
Finally, we just need to solve it for x.
[tex]3(18-x)=5(12-x)[/tex]
[tex]5x-3x=60-54[/tex]
[tex]2x=6[/tex]
[tex]x=3[/tex]
Therefore, the value of x = 3.

Anyone know the answer to this?
Answer:
hello again
Step-by-step explanation:
the radius of the circle is 6mm
for having the circumference we need diameter
for having diameter we should multiply in 2
so:
[tex]d = 2r \\ \\ d = 2 \times 6 = 12mm \\ v = \pi \: d \\ v = 12\pi \: mm[/tex]

2. A water tank is in the shape of a right circular cylinder with a height of 9
feet and a volume of 225 pi cubic feet. What is the diameter of the water
tank? *
Answer:
10 ft.
Step-by-step explanation:
V = Bh where B = area of the base, which is a circle in your problem.
So, B = [tex]\pi r^{2}[/tex]
225π = π[tex]r^{2}[/tex](9)
[tex]r^{2}[/tex] = 25
r = 5 ft
diameter = 2r = 10 ft.
