Angle of elevation is 15 degrees and we're trying to solve for the hypotenuse of the right triangle given the adjacent is 7.11 m. 

We could use primary trig ratios to solve - COS. 

Let x represent the length of the ramp (hypotenuse) 

Cos15= ADJACENT/HYPOTENUSE 
Cos15= 7.11/x 
x=7.11/cos15 
x=7.36 m 

<span>Therefore, the ramp is 7.36 m in length.

ioda

An equivalent ratio would be 4/10, and the number of cattle would be 136,000.Explanation:The question asks for an equivalent ratio. This means a fraction that is equivalent to the fraction between 700-799, which is 2/5.To create an equivalent fraction, we multiply the numerator and denominator by the same number. Multiplying both by 2, we get (2*2)/(5*2) = 4/10.Tenths are useful when dealing with thousands, because taking a tenth involves getting rid of a zero. This means that 1/10 would be 34000; 4/10 would be 4 times that: 4(34000) = 136000.

Choose all that correctly solve for x.
Tamiku [17]

Answer:

Options: A, B, and C correctly solve for x.

Step-by-step explanation:

A).

\frac{5}{2} x = \frac{15}{2}

Multiplying both sides by 2 gives;

5x = 15

x = 15 ÷ 5 = 3

∴ This option correctly solve for x.

B).

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

x = 7 - \frac{7}{2} = \frac{14}{2} -\frac{7}{2} = \frac{7}{2}

∴ This option correctly solve for x.

C).

x + 3 = \frac{21}{5}

x = \frac{21}{5} - \frac{15}{5}  = \frac{6}{5}

But the option give x as 5/6 hence this option does not correctly solve for x.

D).

5x = 11/2

x = 11/2 ÷ 5 = 11/2 × 1/5 = 11/10

But the option gives x as 10/11 so it does not correctly solve for x.
