His error was he put 180 rather than 90 because it’s and acute angle so the number you minus by would be 90 done and then you finish the equation like he did

It’s a 90 degree angle. So the equation so be 28+2x =90 and find x from there.

28+2x=90
-28 -28
2x= 62
x=31

ASAP someone please simply two exponents

zhannawk [14.2K]

Answer:

1.) $m^{15}$

2.) $=\frac{1}{y^{15}}$

Give me a comment if you want the explanation.

1.) $\mathrm{Apply\:exponent\:rule:\:}\left(a^b\right)^c=a^{bc},\:\quad \mathrm{\:assuming\:}a\ge 0$

$\left(m^3\right)^5=m^{3\cdot \:5}$

$\mathrm{Multiply\:the\:numbers:}\:3\cdot \:5=15$

$=m^{15}$

2.) $\mathrm{Apply\:exponent\:rule:\:}\left(a^b\right)^c=a^{bc},\:\quad \mathrm{\:assuming\:}a\ge 0$

$\left(y^{-3}\right)^5=y^{-3\cdot \:5}$

$=y^{-3\cdot \:5}$

$=y^{-15}$

$\mathrm{Apply\:exponent\:rule}:\quad \:a^{-b}=\frac{1}{a^b}$

$=\frac{1}{y^{15}}$

A cylindrical container that contains three tennis balls that are 2.7 inches in diameter is lying on its side and passes through

wolverine [178]

Let's take this problem step-by-step:

Let's take the case of the tennis ball first:

⇒ the diameter of the balls are 2.7inches

⇒ therefore they are spheres with diameters of 2.7 inches

⇒ for an x-ray they are circles with a diameter of 2.7in

Now for the cylinder container:

⇒ It has a width of 2.7inches

⇒ Its height:

⇒ is three balls stacked together

⇒ Height is 3 * 2.7in = 5.4 inches

⇒ Overall dimension: A rectangle that is 2.7 in x 8.1 in

Answer:

A circle with a diameter of 2.7 in
A rectangle that is 2.7 in x 8.1 in

Hope that helps!
