Answer:
39.53
Step-by-step explanation:
Multiply 61 by .4. The answer is 24.4. Subtract 24.4 from 61. This is the sale price after the discount but before the sales tax. The answer to that is 36.6. Multiply 36.6 by .08, the answer is 2.928. Round to the nearest hundreths. Add this to 36.6. You're final answer is 39.53.

7. A cone has a volume of 942 cubic inches
and a height of 9 inches. What is the radius of
the cone?
Answer:
Step-by-step explanation:
V of a cone V=3.14* r^2*h/3
942=3.14*r^2*9/3
r^2=942/(3.14*3)=100
r=sqrt100=10
The radius of the cone when the volume of 942 cubic inches and a height of 9 inches should be 10.
Calculation of the radius of the cone;
Since there is a volume of 942 cubic inches and a height of 9 inches
We know that
Volume of a cone V=[tex]3.14* r^2*h/3[/tex]
So,
[tex]942=3.14*r^2*9/3\\\\r^2=942/(3.14*3)=100[/tex]
r =[tex]\sqrt 100[/tex]
=10
hence, The radius of the cone when the volume of 942 cubic inches and a height of 9 inches should be 10.

how do you work out this equation?
solve simultaneous equations by substitution
x + y =3
5x + y = 15
Step-by-step explanation:
x + y = 3. => y = 3 - x
5x + y = 5x + (3 - x) = 15.
=> 4x + 3 = 15
=> 4x = 12, x = 3.
Therefore y = 3 - (3) = 0.
The solutions are x = 3 and y = 0.
Answer:
Step-by-step explanation:
x+y=3
5x+y = 15
I method:
y = 3 - x. substitute this in 2nd equation
5x + (3-x) = 15
5x + 3 - x = 15
4x = 12
x=3
y=0
II method:
subtracting 2nd equation and 1st equation we get
4x +0y = 12
x = 3
y = 0

What is the solution to the system of equations below?
y- x-3 and x = -10
0 (-10,-7)
0 (-10,-1)
0 (-7, -10)
0 (-1,-10)
Answer:
(-10,-7)
Step-by-step explanation:
the given equations: y=-3 and x=-10
we can substitute the x in the first equation as -10.
y=(2/5×-10)-3
simplify
y=(2/1*-2)-3
y=-4-3
y=-7
the y value is -7
we actually have the x value given as -10 (in the system)
So the answer is (-10,-7)

The prism shown has a volume of 35 cm'.
Work out h, the height of the triangular cross section.
h
7 cm
4 cm
The height of the triangular cross section of the prism will be [tex]2.5 \ cm[/tex] .
What is prism ?Prism is a polyhedron comprising an [tex]n-[/tex]sided polygon base, a second base which is a translated copy of the first, and [tex]n[/tex] other faces, necessarily all parallelograms, joining corresponding sides of the two bases. All cross-sections parallel to the bases are translations of the bases.
And,
Volume of prism [tex]= Base\ Area\ *\ Length[/tex]
We have,
Volume of prism [tex]=35 cm^3[/tex]
Length of prism [tex]=7cm[/tex]
Height of prism [tex]=h\ cm[/tex]
We also have,
Base of triangle [tex]=4\ cm[/tex]
One of the side of triangle [tex]=5\ cm[/tex]
As we have Triangular prism so Base area of prism will be the area of triangle.
so,
Area of triangle [tex]=\frac{1}{2}*base*Height[/tex]
[tex]=\frac{1}{2} * 4*h[/tex]
Area of triangle [tex]=2h[/tex]
Now,
Volume of prism [tex]= Base\ Area\ *\ Length[/tex]
[tex]35=2h*7[/tex]
[tex]h=\frac{5}{2}[/tex]
[tex]h=2.5 \ cm[/tex]
So, the height of prism is [tex]2.5\ cm[/tex] .
Hence, we can say that the height of the triangular cross section of the prism will be [tex]2.5 \ cm[/tex] .

A small aircraft flies a 2160-mi round trip in a 45 mi/h wind. Find the average rate of speed for the trip if the aircraft can fly 225 mi/h with no wind.
9514 1404 393
Answer:
216 mi/h
Step-by-step explanation:
The time for the trip with the wind is ...
(1080 mi)/(225 +45 mi/h) = 4 h
The time for the trip against the wind is ...
(1080 mi)/(225 -45 mi/h) = 6 h
The average speed for the entire round trip is ...
(2160 mi)/(4 +6 h) = 216 mi/h

Answer:
The sets of the domain and the range of T are, respectively:
[tex]Dom \{T\} =\{-3,0,3\}[/tex]
[tex]Ran\{T\} = \{-4.-3,2,3\}[/tex]
Step-by-step explanation:
The values of the relation T that belongs to the domains correspond with the values on the x-axis and associated with the given points, whereas the range corresponds with the respective values of the y-axis. Let [tex]T = \{(x,y)|(-3,3),(3,2),(0,-3),(3,-4)\}[/tex]
