Answer:

114

Step-by-step explanation:

so lets call shelf 1 x

shelf 2 is twice size + 18 of shelf 1 so it is 2(x)+18

shelf 3 is 12 less than shelf 1 so x-12

shelf 4 is four more so x+4

Add them all together and it should be 5x+10= 2.5 m or 250 cm

Solve for x using cm

then plug into shelf 2 equation

By <em>trigonometric</em> functions we find that the measure of angle A is approximately 0.12π radians.

<h3>How to determine the missing angle in a right triangle</h3>

In this question we have a <em>right</em> triangle, of which the length of two sides are known (AB, BC). We can know the measure of angle A by <em>trigonometric</em> functions:

\tan A = \frac{BC}{AC}

\tan A = \frac{2}{5}

A ≈ 0.12π radians

(SAT Prep) In △ABC, AB = BC = 20, DE ≈ 9.28. Approximate BD.
OLga [1]

The measure of BD ≈ 5.36

<u>Step-by-step explanation</u>:

  • The side BC = BD+DE+EC.
  • The measure of BC = 20 and DE ≈ 9.28
  • The angles ∠BD and ∠EC are both equal to 15°
  • If the angles are same, then their sides are equal.

Let 'x' be the measure of BD and EC.

BC = x+9.28+x

20 = 9.28 + 2x

2x = 20-9.28

x = 10.72/2

x = 5.36 (approx.)

∴ The measure of BD ≈ 5.36

X+y=3<br> y+x= 5<br><br> help please
Oksana_A [137]
Solve by elimination ie eliminate x or y from the equations by performing operations on them.
first label the equations , to follow the process.
x - y = 5 ----------------(1)
x+ y = 3 ----------------(2)
If (1) and (2) are added then y will be eliminated.
(1) + (2) gives : 2x = 8 → x = 4
now substitute this value of x into either of the 2 equations and solve for y.
let x = 4 in (1) : 4 - y = 5 → -y = 1 → y = -1
check in (1) : 4-(-1) = 4+1 = 5
check in(2) : 4 - 1 = 3


So your answer is x = 4 , y = -1

Find the value of (64/25)^-1/2 Give your answer as fraction in its simplest form.​
Elis [28]

Answer:

\frac{5}{8}

Step-by-step explanation:

(\frac{64}{25})^{-\frac{1}{2} } has a negative, fractional indice; this negative sign in this context means to make the base fraction a reciprocal (flip it!):

(\frac{25}{64})^{\frac{1}{2}} The denominator is the value by which we should root, then the numerator is the power the fraction should be raised to: [root and then raise]

\frac{(\sqrt{25})^{1}  }{(\sqrt{64})^{1}  } This fraction then becomes:

\frac{5}{8}
