Answer:

104+3(90.5)

Step-by-step explanation:

(127.50+23.50)+3(86.50+4)

Let's take the bracket one after another

(127.50-23.50)

104.00

3(86.50+4)

3(90.50)

271.50

Back to the question

151.00+271.50

422.50

So the answer is 104+3(90.50)

What is 4/p = 11/2 plz help :)
makkiz [27]
Cross multiply
4/p=11/2
(4)*(2)=11*p
8=11p
Flip the equation
11p=8
Divide both sides by 11
11p/11=8/11
p=8/11
hope this helps!

Raise r to the 7th power, then double the result
Minchanka [31]

Answer:

\huge\boxed{\bf\:2r^{7}}

Step-by-step explanation:

Let the variable be taken as 'r'.

Then, by raising it to the 7th power, we'll get the result as \downarrow

 \sf\:Raise \: r \: to \: the \: 7^{th} \: power = r \: with \: 7 \: as \: its \: exponent.\\\\\sf\:Then,\\\dashrightarrow \underline{\bf\:r \: ^{7}}

Now, by doubling the result....

\sf\:To \: double \: the \: result = multiply \: the \: result \: by \: 2.\\\\\sf\:Then,\\\dashrightarrow \sf\:r \: ^{7} \\=\boxed{\bf\: 2r\:^{7}}

\rule{150pt}{2pt}

The answer is not 3,815.10 I checked already but hellpp

The volume of a cylinder is represented by: \pi  r^{2}h

We know that r is equal to \frac{1}{2}d, and d in this case is 9 in. Therefore, r = 4.5 in.

Then, using 3.14 for \pi, and 15 in. for height, we can solve for the volume of the cylinder:

V=3.14 (4.5)^{2} (15)

V=3.14*20.25*15

V=953.775 in^{3}

By using this equation, we were able to determine that the volume of this cylinder is 953.775 in^{3}.
