10(x - 5) = -80 find the value of
Answer:
the value of x = -3
Step-by-step explanation:
10 (x-5) = -80
10x - 50 = -80
10x = -30
x = -3
CHECK:
10 ( -3 - 5) = -80
10 (-8) = -80
-80 = -80
Factor -x^3+17x^2-70x

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

Question 11Angles B with A are complementary, so as angles F with D
15 + 75 = 90
The triangles are similar by AA
---------------------------------------
Question 10The missing angle E:
m∠E = 180° - (44° + 30°) = 106°The corresponding angle B is not congruent with E:
106° ≠ 116°The triangles are not similar
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

similarity of right angle triangle
Answer:
The triangles pictured are similar (SSS), that is the corresponding sides are in the same ratio. Hence the matching angles are the same. For any right-angled triangle similar to triangle ABC, the ratio of the matching sides will be the same.
Use the bar graph to find the experimental probability of the event. The experimental probability of spinning a 4 is __.
Answer:
Assuming the spinner has 6 parts: 1/6 chance of landing on 4 (theorectical probability)
Step-by-step explanation:
Since you did not give me the bar graph, I cannot see the results of the experiment and so I assume that there are 6 equal parts in the spinner.
To figure out the Ex. Pro., do favorable outcome/possible outcome.

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.

Find the height of the square prism if the volume is 1344 cubic meters and the base edge is 12 meters
Answer: 9.33 meters (9 1/3 meters)
Step-by-step explanation:
If the base edge is 12 m and the base is a square, square the edge length. (12*12=144). The volume of a prism is the area of the base times the height, so the height is the volume divided by the area of the base. Divide 1344 by the area of 144 (1344/144=9.33 or 9 1/3)
Answer:
9.33 meters
Step-by-step explanation:
The formula to find the volume of a square prism is [tex]V=a^2h[/tex]. To solve for [tex]h[/tex], the formula becomes [tex]h=\frac{V}{a^2}[/tex].
Plug in the base edge and the volume.
[tex]h=\frac{1344}{12^2}[/tex]
[tex]\frac{1344}{12^2}[/tex] [tex]=[/tex] 9.33.
The height of the prism, then, is 9.33 meters.
I hope this helps ^^ Good luck :]
The large sphere has a diameter of 20 feet. Which expression represents the volume, in cubic units, of the shaded part of the sphere? 4f 0 (106) + M4 ㅇ (10) - [4) ㅇ (20) + (4) ㅇ (20) - (43)
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.
