Answer:
777 fewer belts

SOH-CAH-TOA..............
Answer:
Step-by-step explanation:
oh nice, SOH CAH TOA :P
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
SOH CAH TOA is really helpful, it also reminds me of south pacific for some reason :D
Anyway back to math
we want to find an angle and we have the Hyp and the adj sides
to that angle soooo
let's pick CAH since it's got Adj / Hyp , which we know and will find that unknown angle for us.. :)
Cos(Ф) = Adj / Hyp
Ф = arcCos( adj / Hyp)
Ф = arcCos( 14 /28 )
Ф = arcCos(.5) ( if you happen to be good with trig functions you can already tell what it's going to be :P w/o using the calculator)
Ф = 60 °
1a = 60 °
for 1b we know the opp and they hyp and want to find the angle. So let's use SOH
sin = Opp / Hyp
sin(Ф) = 5/20
Ф = arcSin(5 /20)
Ф = arcSin ( 1/4)
Ф = 14.4775 °
1b = 14 ° ( rounded to nearest degree )

Answer:
[tex]\huge\boxed{960}[/tex]
Step-by-step explanation:
To find the volume of a rectangular prism we use the formula
Volume = length x height x width
the following dimensions are given
12 - width
10 - height
8 - length
so all we have to do is plug in the values into the formula
volume = 12x10x8=960
so we can conclude that the volume of the ice cooler is 960
Answer:
12 times 8 equals 96 times 2 equals 192
10 times 8 equals 80 times 2 equals 160
10 times 12 equals 120 times 2 equals 240
240 plus 160 plus 192 equals 592

please, please, please, help me. this is 100 points. I only have 20 more minutes, if you could help that'd be amazing. Im running out of time and am really stressed. Attached is my question.
Answer:
Step-by-step explanation:
If you complete the square and double the time to get back to the surface you will have your answer.
d = 2(t^2 - 4t) - 10; Take 1/2 of - 4 and square it. Add the result inside the brackets.
d = 2(t^2 - 4t + (4/2)^2 ) - 10
d = 2*(t^2 - 4t + 4) - 10 - 2*4
Did you notice I put the 2*4 outside the brackets and turned it into a minus. The reason that happened is to offset what is inside the brackets that was added here.
d = 2(x - 2)^2 - 18; t^2 - 4t + 4 is a perfect square. that 2 inside the brackets is critically important.
The 18 is the maximum depth below the surface of the water. (Poor choice of words. Technically - 18 is a minimum). But you want to use t - 2 to make it into 0. t - 2 = 0 ; t =2
What that means is that it took 2 minutes to get 18 meters below the surface of the water. He will break the surface of the water 2 minutes later. I don't exactly know how to answer the question. It is 2 minutes to get from the minimum depth to the surface. It is 4 minutes to get to the surface when he begins his dive.
Come back to the surface means d=0
2t²-8t-10=02t²-10t+2t-10=02t(t-5)+2(t-5)=0(2t+2)(t-5)=0t=-1 and t=5Take positive
t=5s
S varies inversely as G. If S is 9 when G is 2.4, find S when G is 6. a) Write the variation. b) Find S when G is 6
Answer:
S = 21.6/G
S = 3.6
Step-by-step explanation:
Inverse variation:
y = k/x
For this problem:
S = k/G
We use the given values of S and G to find k.
9 = k/2.4
k = 9 * 2.4
k = 21.6
The equation is
S = 21.6/G
For G = 6,
S = 21.6/6
S = 3.6

Juan has 36 in of string how many 3 and 1/4 in pieces can one cut from the string? a. 8 b.9 c.11 d.12?
Answer:
c. 11
Step-by-step explanation:
36 divided by 3.25 is a little over 11. That little extra is a remainder and cannot be put into 3.25 again, and so 11 is the right answer.
Juan can cut a maximum of 11 pieces from the string.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
We have two types of fractions.
Proper fraction and improper fraction.
A proper fraction is a fraction whose numerator is less than the denominator.
An improper fraction is a fraction where the numerator is greater than the denominator.
Example:
1/2, 1/3 is a fraction.
3/6, 99/999 is a fraction.
1/4 is a fraction.
We have,
To find out how many 3 and 1/4-inch pieces Juan can cut from his 36-inch string, we can divide the length of the string by the length of each piece.
First, we need to convert 3 and 1/4 inches to a decimal form:
3 and 1/4 inches = 3.25 inches
Now we can divide the length of the string by the length of each piece:
36 inches ÷ 3.25 inches/piece ≈ 11.08 pieces
Thus,
Since Juan cannot cut a fraction of a piece, he can cut a maximum of 11 pieces from the string.
