Please help.

Answer:
27.1 cm
Step-by-step explanation:
The area of the solid is the lateral area of the cylinder plus the total area of the cone of unknown height. In terms of the cone's slant height (s), the total area of the solid is ...
A = πdh +πr(r +s) . . . . diameter d, height h, radius r, slant height s
458 = π(6·18 +3(3+s))
145.786 = (108 +9 +3s)
28.786 = 3s
s = 9.595
Then the height of the cone is found from the Pythagorean theorem as ...
√(s² -3²) ≈ 9.1 . . . . cm
The total height of the solid is about ...
18 cm +9.1 cm = 27.1 cm

3x -2y = -6 and y = x+5
Answers
Answer:
x = 4, y = 9.
Step-by-step explanation:
3x -2y = -6 and y = x+5
Substitute y = x + 5 in the first equation:
3x - 2(x + 5) = -6
3x - 2x - 10 = -6
x = -6 + 10
x = 4
So y = 4 + 5 = 9.

Answers
Answer:
2= 95 degrees
3= 25 degrees
1= 60 degrees
5= 25 degrees
4= 95 degrees
Step-by-step explanation:
2) Straight line is 180 degrees so
180-85=95 degrees
3) I got 25 degrees because it's a corresponding angle of X, which is parallel to 25.
1) A triangle is always 180 degrees, 95+25=120 180-120=60
5) Its another corresponding angle to 25
4) Straight line is 180 degrees 60+25=85 180-85=95
Or you could of worked out the bottom 85 and minus it from 180 which will also correspond to 4

Answer:
18 6/7 ft
Step-by-step explanation:
The circumference is given by the formula ...
C = 2πr
The circumference of the larger circle is then ...
C' = 2π(r+3) = 2πr +6π
The difference in circumference is ...
C' -C = (2πr +6π) -(2πr) = 6π
For the given value of π, the difference in circumference is ...
(22/7)(6 ft) = 132/7 ft = 18 6/7 ft
The circumference of the outer circle is greater by 18 6/7 ft.

Step-by-step explanation:
If I'm reading your shorthand correctly you want this to be rounded to 3 digits.
There are two answers:
1) 8.27 * 10^2 which is the best way to show 3 significant digits or
2) 827 which works but is not as good as the scientific notation.
The reason is that you cannot be absolutely sure how many digits there are. It might just be a convenient way to show a number informally without worrying about significant figures.

= -3x² (2x+4)
= -6x³ - 12x²
b). f(g(-1))
g(-1) = 2(-1) + 4
= -2 + 4
= 2
f(2) = -3x²

Answer:
2.4 cm
Step-by-step explanation:
We know the length of segment AB and the length of segment BC. To find their midpoints, we can divide their length by 2.
Let's find the midpoint of AB.
Segment AB: 10 cm Midpoint of AB: 10/2 = 5 cmNext let's find the midpoint of BC.
Segment BC: 5.2 cmMidpoint of BC: 5.2/2 = 2.6 cmIn order to find the difference between these midpoints, we can subtract the midpoint of AB by the midpoint of BC.
5 cm - 2.6 cm = 2.4 cmTherefore, the difference between the midpoints of AB and BC is 2.4 cm.

Step-by-step explanation:
Un coeficiente es un número o símbolo multiplicado por una variable o una cantidad desconocida en un término algebraico, polinomio, una serie o cualquier expresión.
a) 5x² + 4x + 2 = 0
El coeficiente de x² = 5, el coeficiente de x = 4
b) –x² + 3x + 4 = 0
El coeficiente de x² = -1, el coeficiente de x = 3
c) x² - 4x + √7 = 0
El coeficiente de x² = 1, el coeficiente de x = -4
d) x² + 8 = 0
El coeficiente de x² = 1, el coeficiente de x = 0
