Answer:
For cylinder TSA this is simple equation TSA - TBA = LSA
total surface area subtract the total base area and we get the lateral.
To find base it is 2pi r^2
so 2pi x r x h - 2 pi x r^2 = lateral surface area
Step-by-step explanation:
Answer:
Measure of angle M = 41°
Step-by-step explanation:
From the figure attached,
NM ≅ NO [Given]
Therefore, ∠O ≅ ∠M [Opposite angle of the equal sides]
By triangle sum theorem,
m∠O + m∠N + m∠M = 180°
m∠O + m∠N + m∠O = 180° [Since, ∠M ≅ ∠O]
By substituting the values of the given angles,
(4y - 15)° + (7y)° + (4y - 15)° = 180°
(15y - 30) = 180
15y = 210
y = 14
Therefore, m∠M = (4y - 15)°
= 4(14) - 15
= 56 - 15
= 41°
Multiplicative inverse makes the numver 1 so it multiplies by 1 which cancles the number
examle
1/3x=10
to make 1/3 into 1
we multiplyu it by its mutlipcative invers which is 3/1
1/3 times 3/1=3/3=1
1/3x times 3/1=3/1 times 10
1x=30
additive inverse makes the number 0 to cancel it out
so example
x+3=10
add the inverse of 3 to make it 0
inverse of 3 is -3
3+-3=0
so x+3-3=10-3
x+0=7
x=7
(a) 2.49 * 6 = 14.94 <== what they spent on goodie bags
(b) 150 for 8 hrs = 150/8 = 18.75 per hr
(c) 182.53 - (150 + 14.94) = 182.53 - 164.94 = 17.59...they spent 17.59 more
