The correct equation is:

216 = \frac{7}{8} \times x - 8

The volume of second cylinder is 256 centimeter cubed

<em><u>Solution:</u></em>

Given that,

One cylinder has a volume that is 8cm less than 7/8 of the volume of a second cylinder

The first cylinder’s volume is 216 centimeter cubed

From given,

Let "x" be the volume of second cylinder

Therefore,

Volume of first cylinder = 7/8 of the volume of a second cylinder - 8

216 = \frac{7}{8} \times x - 8

216 = \frac{7x}{8}-8\\\\216 = \frac{7x-64}{8}\\\\7x - 64 = 8 \times 216\\\\7x - 64 = 1728\\\\7x = 1728 + 64\\\\7x = 1792\\\\Divide\ both\ sides\ by\ 7\\\\x = 256

Thus the volume of second cylinder is 256 centimeter cubed

A rectangular parking lot is 120 feet long and 75 feet wide. Diego made another scale drawing of the parking lot at a scale of 1
andrew11 [14]

Answer:

We kindly invite you to read carefully the explanation detailed below for further details.

Step-by-step explanation:

At first we understand that Diego converted length and wide units from feet to inches (1\,ft = 12\,in) and then he divided each term by 180, since he was using a reduction scale, so that rectangular parking lot can be represented on paper. That is:

Step 1 - Unit conversion:

l = 120\,ft (l - Length)

l = 120\,ft\times \frac{12\,in}{1\,ft}

l = 1440\,in

w = 75\,ft (w - Width)

w = 75\,ft\times \frac{12\,in}{1\,ft}

w = 900\,in

Step 2 - Applying scaling:

l' = \frac{l}{180} (l' - Scaled length)

l' = \frac{1440\,in}{180}

l' = 8\,in

w' = \frac{w}{180} (w' - Scaled width)

w' = \frac{900\,in}{180}

w' = 5\,in

Find the measures of the numbered angles in the isosceles trapezoid.
torisob [31]

Answer:

Step-by-step explanation:

in an isocelles trapezoid, we have the properties:

the lower base angles are congruent

the upper base angles are congruent

we have an angle= 44

the angle #3= 44 because of the properties

so the lower base angles are equal and equal to 44

sum of the angles in trapezoid=360

360-(44*2)=360-88=272

upper base angles are equal

272/2=136

angle1=angle2=136
