Answer:
p = 20, q = 20, r = 30
Step-by-step explanation:
The triangle to the left of OA is isosceles ( 2 equal radii ), then the base angles are congruent, so
p = 20
The 3 angles in this triangle sum to 180°, then the angle at O is
180 - (20 + 20) = 180 - 40 = 140°
AB is a straight line so angle in triangle containing q is 180 - 140 = 40
The triangle containing q is also isosceles ( 2 equal radii ) then base angles are congruent, then
q = [tex]\frac{180-140}{2}[/tex] = [tex]\frac{40}{2}[/tex] = 20
The triangle to the right of OA is also isosceles ( 2 equal radii ) then the base angles are congruent, so
r = 30
Then p = 20, q = 20, r = 30

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
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?
Answers
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]

When there is a negative in front of the exponent it makes a fraction. It is usually just 1/the number it equals if it were positive.
Answer:
[tex] \frac{1}{81} [/tex]
Step-by-step explanation:
express that with a positive exponent using this:
[tex] {a}^{ - n} \frac{1}{ {a}^{n} } [/tex]
so ..
[tex] {9}^{ - 2} = \frac{1}{ {9}^{2} } [/tex]
now you have to evaluate the exponent/ power
so..
[tex] \frac{1}{ {9}^{2} } = \frac{1}{81} [/tex]
why 81 ?
because the exponent of 9 is 2 so you have to multiple 9 by itself so
9x9=81
so the answer is
[tex] \frac{1}{ {81}^{} } [/tex]

Which ordered pair is a solution of the equation y = 10x?
A. (−6, −60)
B. (8, 90)
C. (8, 70)
D. (−10, −80)
Answers
Basically, you have to plug in your coordinate to the equation. Plug in -60 for y and -6 for x. Now it should look like:
-60 = 10(-6)
Multiply 10 by -6 to get:
-60 = -60
That is a true statement because -60 equals -60. So, A is a solution to the equation. Hope this helped!
