Mathematics

Answer:

x=12

Step-by-step explanation:

5x+4+64+52=180

We move all terms to the left:

5x+4+64+52-(180)=0

We add all the numbers together, and all the variables

5x-60=0

We move all terms containing x to the left, all other terms to the right

5x=60

x=60/5

x=12

Marci needs to rent a storage unit. She needs to determine the volume of the storage unit to decide if the storage unit is big e
stealth61 [152]

Answer:

Volume = 176ft^3

Step-by-step explanation:

Given

Height = 8

See attachment for base dimension

Required

Determine the volume of the storage unit

From the attachment, we can split the base dimension into two rectangles.

CDEF and ABCG

And the dimensions are:

<u>CDEF</u>

EF = CD = BD - BC = 5 - 2 = 3

ED = FC = FG +AB = 4 + 2 =6

So, the area of CDEF is:

Area = EF * ED

Area = 3 * 6

Area = 18

<u>ABCG</u>

<u></u>AB= GC = 2<u></u>

<u></u>AG = BC = 2<u></u>

<u></u>

<u></u>Area = AB * AG<u></u>

Area = 2 * 2

Area = 4

So, the base area is:

Base\ Area = 18 + 4

Base\ Area = 22

The volume is then calculated as:

Volume = Base\ Area * Height

Volume = 22 * 8

Volume = 176

Can someone solve this?
aleksley [76]

Answer:

Considering the Law of Cosines:

c^2=a^2+b^2-2ab*cosC

a=14mi; b=24mi; c=CA; C=91degrees

\cos \left(91^{\circ \:}\right)=-0.01745\dots

c^2=14^2+24^2-2(14)(24)*\cos \left(91^{\circ \:}\right)\\c^2=196+576-672*\cos \left(91^{\circ \:}\right)\\c^2=772-672*\cos \left(91^{\circ \:}\right)\\c^2=772-672*(-0.01745)\\c^2=772+11.7264\\c=\sqrt{772+11.7264} \\c=\sqrt{783.7264}\\c=27.99mi

aev [14]

Answer:

x=2

Step-by-step explanation:

5x+\frac{4}{2} = 7

5x+4 =7 (2)

5x+4=14

5x=14-4

5x=10

\frac{5x}{5} = \frac{10}{5}

x=2
