Answer: 12
Step-by-step explanation:
law of cosines states that f^2 = t^2 + p^2 - 2tp cos(F)
so f^2 = 5^2 + 7^2 - 2*5*7*cos(175)
f^2 = 74 - (-69.7336)
f^2 = 143.7336
f = 11.9889
which rounds to 12
Answer:
<h2><u><em>
no</em></u></h2>
Step-by-step explanation:
Can 10 people be divided into two groups with a ratio of 1 : 2?
Explain.
10 : 3 = 3.33
or 10 : 3 = 9 remaining 1
since it is not possible to divide a person into three parts, your answer is no
Closer to 1 because it’s nearly a 7/7 which is also known as 1.
Answer:
x = -5/4, x= -7
Step-by-step explanation:
Using the zero product property to solve this equation,
<u>4x+5 = 0</u>
4x = -5
4x/4 = -5/4
x = -5/4
<u>x+7 = 0</u>
x = -7
Answer:
(a-b) = -25
Step-by-step explanation:
(a+b) = -5
a*b=-150
So one of the letters have to be negative as you can only get a negative product from a positive and negative
There is probably a better way to do this, but I just plug in numbers that I think will work
So, (a*b) = -150, (-15*10) = -150
Okay that works so lets try the other one
(-15+10) = -5
This also works, so lets do the third one
(-15-10) = -25
