Answer:

Isolate x by multiplying by 4 to each side of the inequality

Step-by-step explanation:

You have x in a fraction, and you want to have x by itself on one side of the equation. In this case, you need to multiply by 4 to each side of the inequality to cancel the 4 on the left hand side of the inequality and leave x on its own. The final inequality is $x>52$ .

If I helped, a brainliest answer would be greatly appreciated!

Answer:

a = 50°, b = 130°, c = 20°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles in the right triangle

a + 40° + 90° = 180°

a + 130° = 180° ( subtract 130° from both sides )

a = 50°

a and b are adjacent angles and sum to 180° , so

a + b = 180°

50° + b = 180° ( subtract 50° from both sides )

b = 130°

Then sum the angles in the top triangle, that is

30° + 130° + c = 180°

160° + c = 180° ( subtract 160° from both sides )

c = 20°

Find the measure of the arc or central angle indicated. Assume that lines which appear to be diameters are actual diameters.

vfiekz [6]

The measure of the Central Angle indicated is; 45°

<h3>How to find the central angle of a circle?</h3>

The central angle will be the angle subtended at the center by arc FE and arc CB.

Now, we see that angle ∠FOB = 135° and since we know that sum of angles on a straight line is 180°, then we can say that;

Central Angle = 180° - 135° = 45°

Angle subtended by Arc CD at the center is;

θ = 180 - (81 + 45)

θ = 54°

Which expression is equal to 5^4 x 5^8 ? <br><br> A: 5^12<br> B: 5^4<br> C: 5^2<br> D: 5^−4

galben [10]

Something to remember is how to multiply terms with same bases, but different exponents:

$a^b \cdot a^c = a^{(b+c)}$

Essentially, we add the exponents.

Using the information above, we can find our answer:

$5^4 \cdot 5^8 = 5^{(4+8)} = \boxed{5^{12}}$

Our answer is $\boxed{5^{12}}$ , or A.
