Step-by-step explanation:
[tex] \sin(a) = \frac{7}{25} = 0.28 \\ \sin(b) = \frac{24}{25} = 0.96 \\ \cos(a) = \frac{24}{25} = 0.96 \\ \cos(b) = \frac{7}{25} = 0.28 [/tex]
tan(A)= 7/24= 0.29
tan(B)= 24/7=3.42
A=16.26°
B=73.73°

Given that 3x – 8y = 39
Find y when x = 3
Give your answer as an improper fraction in its simplest form.
Answer:
- [tex]\frac{15}{4}[/tex]
Step-by-step explanation:
Given
3x - 8y = 39 ← substitute x = 3 into the equation
3(3) - 8y = 39
9 - 8y = 39 ( subtract 9 from both sides )
- 8y = 30 ( divide both sides by - 8 )
y = [tex]\frac{30}{-8}[/tex] = - [tex]\frac{15}{4}[/tex]
A dog weighs 60 N on planet Earth. On the moon, he would weigh about
176 (one-sixth) of what he does on Earth. How much does the dog weigh on
the moon?
Answer:
16.09N
Step-by-step explanation:
Answer:
[tex]\boxed{\purple{\textsf{The weight of the dog on moon is \textbf{10 Newtons. }}}}[/tex]
Step-by-step explanation:
Given that the weight of the dog on the earth is 60N . We need to find the weight of dog on the moon. So we know that the weight of an object is one sixth the weight of an object on the moon. In other words the acceleration due to gravity is one sixth on the moon that of earth. We can use a formula as ,
[tex]\qquad\boxed{\boxed{\sf Weight_{(On \ moon )}= \dfrac{1}{6}\times Weight_{(On \ earth )}}}[/tex]
On substituting the respective values :-
[tex]\sf\implies Weight_{(On \ moon )} = \dfrac{1}{6}\times Weight_{(On \ earth )} \\\\\sf\implies Weight_{(On \ moon )} =\dfrac{1}{6}\times 60 N \\\\\sf\implies\boxed{\pink{\frak{ Weight_{(On \ moon )}= 10 \ Newtons }}}[/tex]

make m the subject of the formula
G = √m-5 /2
g² = m-5 /2
2 × g² = m - 5
2g² = m - 5
2g² + 5 = m
So, m = 2g² + 5
Answer:
m = 2G²+5
Step-by-step explanation:
G²= m-5/2
2g² = m-5
2g² +5 = m
m = 2G²+5
