Answer:

14.8 pounds

Step-by-step explanation:

Here, we want to get the actual value made of fat from the body weight

What we have to do here is to multiply the percentage by the body weight

Mathematically, we have this as;

18.8% of 127 pounds

= 18.8/100 * 127 = 14.80 pounds

Step-by-step explanation:

Given data

let adults be x

and student be y

so

6x+15y= 48-----------1

and

8x+7=38-----------2

solve eqn 1 and 2

6x+15y= 48-----------1X 8

8x+7=38-----------2X 6

48x

+15y= 40

48x+7y= 38

subtract

8y=2

y= 2/8

y= 1/4

y= $0.25

from 8x+7=38

put y= 0.25

8x+7(0.25)=38

8x+1.75= 38

8x=38-1.75

8x=36.25

x=36.25/8

x=$4.5

Answer its rhombus

Step-by-step explanation: i took the test

The quadrilateral formed by the taping together of two equilateral

triangles is a rhombus.

The given types of triangles that form the quadrilateral are equilateral

triangles.

Given that the triangles have congruent side lengths, we have;

1) The side lengths of the quadrilateral formed are equal.

2) A pair opposite angles of the quadrilateral formed are equal to the interior angle of an equilateral triangle which is 60°.

3) The other pair of opposite angles are also equal to 60° + 60° = 120°.

The altitude of an equilateral triangle is perpendicular to the base.

Which gives;

4) The diagonals bisect each other at right angles.

Therefore;

The adjacent angles are supplementary

Which gives;

5) The opposite sides are parallel.

The above properties are the properties of a rhombus

Therefore;

Answer:

The small box contains 21 cans

Step-by-step explanation:

Represent the small box with S and the large with L.

For Estelle:

[tex]3L + 5S = 170[/tex]

For the boy:

[tex]4L + 4S = 184[/tex]

Required

Determine the cans in the small box

[tex]3L + 5S = 170[/tex] --- (1)

[tex]4L + 4S = 184[/tex] --- (2)

Divide (2) through by 4

[tex]L + S = 46[/tex]

Make L the subject

[tex]L = 46 -S[/tex]

Substitute 46 - S for L in (1)

[tex]3L + 5S = 170[/tex]

[tex]3(46 - S) + 5S = 170[/tex]

Open bracket

[tex]128 - 3S + 5S = 170[/tex]

[tex]128 + 2S = 170[/tex]

Collect Like Terms

[tex]2S = 170-128[/tex]

[tex]2S = 42[/tex]

Divide both sides by 2

[tex]S = 21[/tex]

Hence, the small box contains 21 cans

Answer: 387 1/2 miles

Step-by-step explanation:

From the question, we know that 20 gallons can be used for 500 miles. Therefore, the gallons of gas per mile will be:

= 500/20

= 25 gallons per mile.

The number of miles that a 15 1/2 gallons will use will be:

= 25 × 15 1/2

= 387 1/2 miles
