Answer:
13,680millimetres of water are blown
Step-by-step explanation:
1/100litre of water is equaled to 10 millilitres
:• 4/100 litres= 40millilitres
they are 342 guests if each guest blows a bottle of bubble containing 40millilitres the to get the total of milliliters blown u gotta multiply the amount of guest by the total millitres for one bottle to set down u will put
342 guests × 40 millitres= (13680) amount of bubble blown
Answer:
17.2°
Explanations
To find angle A, use the cosine rule.
a^2 = b^2 + c^2 - 2 × a × c cos A
4^2 = 7^2 + 10^2 - 2 × 7 × 10 cos A
16 = 49+ 100 - 140 × cosA
16 = 149 - 140cosA
16- 149 = - 140cosA
-133 = - 140cosA
cosA = 133/140
cosA = 0.95
A = 17.2°
The Pythagorean theorem states:
where a and b are the lengths of the legs and c is the length of the hypotenuse of a right triangle.
Substituting with a = 80 and b = 39, we get:

Answer:
28.0001
Step-by-step explanation:
im pretty sure
2t+3n=9 2(2)+3n=9
+5t-3n=5 (the 3n cancel out) 4+3n=9
7t=14 3n=5
t=2 n=5/3 or 1.67
