Use the formula for volume=LWH
Answer:
h = 31.92
Step-by-step explanation:
v = πr^2 h, so
25πh = 2507
Answer:
The standard form is: y = -3x² +18x -24.
Step-by-step explanation:
Given is y = -3(x-2)(x-4)
Using FOIL method to expand the parentheses:-
y = -3(x-2)(x-4)
y = -3(x² -2x -4x +8)
Combining like terms:-
y = -3(x² -6x +8)
Distributing -3 to the terms inside parentheses:-
y = -3x² +18x -24.
Hence, standard form is: y = -3x² +18x -24.
a) n° + n°+ 42 = 180°
2n + 42 = 180
2n = 180 – 42
2n = 138
n = 138 /2
n° = 69°
_____o___o____
b) ( x+10) + x + ( x+5 ) = 180
x + 10 + x + x + 5 =180
3x + 15 =180
3x =180 – 15
3x = 165
x = 165 /3
x° = 55°
_____o___o___
c) 3q + q + q = 180
5q =180
q = 180/5
q=36°
___o___o____
d) m + 2m + ( m+10) = 180
m+2m+m+10=180
4m + 10=180
4m = 180 – 10
4m = 170
m=170 / 4
m = 42.5°
____o___o___
e) y + (y – 30 ) + 90° = 180°
y + y – 30 + 90 = 180
2y + 60 = 180
2y = 180 – 60
2y = 120
y = 120/2
y = 60°
____o___o____
f) ( t + 10.5 ) + 2t + 90 = 180
t + 10.5 + 2t +90=180
3t + 100.5 = 180
3t = 180 – 100.5
3t = 79.5
t = 79.5/3
t =26.5°
I hope I helped you^_^
1. add the factors in the parentheses together first (275+192) - end up with 467
2. add 622 and 467 (end up with 1,089)
3. subtract 513 from both sides of the equation
4. you will end up with the equation of (259+x) = 576
5. subtract 259 from both sides of the equation
FINAL ANSWER
x = 317
hope this helps:)
