The expression that is equivalent to 0.40a is \frac 25a

<h3>What are equivalent expressions?</h3>

Equivalent expressions are expressions that have equal values, when evaluated or simplified

The expression is given as:

0.40a

Rewrite the above expression as a fraction

\frac 4{10}a

Simplify the fraction

\frac 25a

Hence, an equivalent expression of 0.4a is \frac 25a

A surveyor standing on top of a cliff found that the angle of depression of a boat as sea is 22°. if the top of the cliff is 15m
Alex73 [517]

Answer:

From the photo above i interpreted the question and drew a triangle to make it easier to solve

Tan is used to solve the question as we were given opposite (as height of the cliff) and to find Adjacent ( the distance between the foot of the cliff to the boat)

Tan θ =Opp/Adj

Tan 22°=15/a

Cross Multiply

aTanθ=15°

Divide both sides by Tan 22

aTan22/Tan22 = 15/Tan 22

a = 15/Tan 22°

a = 37.13 m

Therefore the distance between the foot of the cliff to the boat is 37.13 metres

Solve the equation <br> 14(3x-1)=2x-23
irina1246 [14]

Answer:

x=\frac{-9}{40} \\

Step-by-step explanation:

Given Equation:

           14(3x-1)=2x-23

Solving the bracket on L.H.S

        (14)(3x)-1(14)=2x-23

             42x-14=2x-23

Taking the terms of 'x' to one side and the constants to other side

                 42x-2x=-23+14\\\\40x=-9\\\\x=\frac{-9}{40} \\

The value of 'x' after solving the equation is:

                            x=\frac{-9}{40} \\

Chris answered 61 out of 66 questions correctly on a test. What is his test average to the nearest thousandth
mars1129 [50]
If you divide 61 by 66, you will get .9242424. The thousandths place is the third number, so you base it off of the four number. If the fourth number is under 5, the third number stays the same and all numbers after it disappear. If the number is above 5, the third number rounds up 1 and the rest disappear. Because the 3rd number is 4 and the 4th number is 2, you will get the answer of .924
