Can someone help with this. Heads up it's ratios
ohaa [14]

Answer:

<em>The median side measures 92 yards</em>

Step-by-step explanation:

Let's call x, y, and z the measures of the sides of the triangle.

The ratios between them are:

\displaystyle \frac{x}{y}=\frac{4}{7}

\displaystyle \frac{x}{z}=\frac{4}{2}=2

The first ratio gives the relation:

\displaystyle y=\frac{7x}{4}

The second ratio can be solved for z:

\displaystyle z=\frac{x}{2}

Since the perimeter is 299 yards:

x+y+z=299

Substituting the above relations:

\displaystyle x+\frac{7x}{4}+\frac{x}{2}=299

Multiplying by 4:

4x + 7x+2x=1196

Joining like terms:

13x=1196

Dividing by 13:

x=1196/13

x=92

Now calculate y:

\displaystyle y=\frac{7\cdot 92}{4}

y = 161

\displaystyle z=\frac{92}{2}

z=46

The median side measures 92 yards

AleksandrR [38]

Answer:

Charges of Turkey is $6.25

Charges of French Fries is $1.90

Step-by-step explanation:

Given

Represent Turkeys with T and French Fries with F;

4T + 7F = 38.3

5T + 5F = 40.75

Required

Determine the values of T and F

5T + 5F = 40.75

Divide through by 5

T + F = 8.15

Make F the subject

F = 8.15 - T

Substitute 8.15 - T for F in the first equation

4T + 7F = 38.3

4T + 7(8.15 - T) = 38.30

4T + 57.05 - 7T = 38.30

Collect Like Terms

4T  - 7T = 38.30 - 57.05

-3T = -18.75

Solve for T

T = -18.75/-3

T = 6.25

Recall that:

F = 8.15 - T

F = 8.15 - 6.25

F = 1.90
