Sholpan [36]
To solve this expression, we need to plug r into the equation.

1 + (5)2 - (5)
= 1 + 10 - 5
= 11 - 5
= 6

Hope this helps!

One number is 3 less than another number if their sum is 49
Musya8 [376]
One number is 26 the other is 23


x+y=49

Y=x+3,X (now substitute it in the equation)

x+3+x=49

2x+3=49

2x=46. X=23


Y=x+3. Y=23+3 =26 for checking 23+26=49

2(5m^4n^-1)^3 simplify show work please
dangina [55]

Answer:

\large\boxed{2(5m^4n^{-1})^3=250m^{12}n^{-3}=\dfrac{250m^{12}}{n^3}}

Step-by-step explanation:

\text{Use}\\\\(ab)^n=a^nb^n\\\\(a^n)^m=a^{nm}\\\\a^{-n}=\dfrac{1}{a^n}\\-------------------\\\\2(5m^4n^{-1})^3=2(5)^3(m^4)^3(n^{-1})^3=2(125)m^{3\cdot4}n^{-1\cdot3}=250m^{12}n^{-3}=\dfrac{250m^{12}}{n^3}

I’m confused on this one
Elina [12.6K]
The question is asking for the sector arc length WZ,which can be find through the sector formula:
2\pi \: r \times  \frac{angle}{ {360}^{o} }
Since both cz and wz are the radius, they have the same length
cz=wz=5 in.

In this case,
2丌(5)× 122°/360°
=10丌×61/180
=61/36 ×丌
≈5.32in.

Thus 5.32in. is the answer.

Hope it helps!
