What is 490% written as a decimal?

1 answer:

5 0

If we first convert it to a fraction, we get 490/100. Now if we actually do 490 ÷ 100, we get 4.9, which is the answer. I hope this helps!

Solve the inequality. 2(4+2x)>5x+5 oxs-2 O X2-2 xs3 x23

mafiozo [28]

For this case we must resolve the following inequality:

$2 (4 + 2x)> 5x + 5$

Applying distributive property on the left side of inequality we have:

$8 + 4x> 5x + 5$

Subtracting 5 from both sides of the inequality:

$8-5 + 4x> 5x\\3 + 4x> 5x$

Subtracting 4x from both sides of the inequality:

$3> 5x-4x\\3> x$

Thus, the result is $x$

Answer:

$x$

Is D the right answer please help!

Leto [7]

The correct answer is C.
-5 is not greater than -3. Negatives are tricky; remember that the closer a negative is to zero, the greater that quantity actually is.

A 25-foot ladder is placed against a vertical wall. Suppose the bottom of the ladder slides away from the wall at a constant ra

dsp73

Answer: The ladder is sliding down the wall at a rate of $5\dfrac{17}{50}\ ft/sec$

Step-by-step explanation:

Since we have given that

Length of ladder = 25 foot

Distance from the wall to the bottom of ladder = 15 feet

Let base be 'x'.

Let length of wall be 'y'.

So, by pythagorus theorem, we get that

$x^2+y^2=25^2\\\\15^2+y^2+625\\\\225+y^2=625\\\\y^2=625-225\\\\y^2=400\\\\y=\sqrt{400}\\\\y=20\ feet$

$\dfrac{dy}{dx}=-4\ ft/sec$

Now, the equation would be

$x^2+y^2=625\\$

Differentiating w.r.t x, we get that

$2x\dfrac{dx}{dt}+2y.\dfrac{dy}{dt}=0\\\\2\times 15\dfrac{dx}{dt}+2\times 20\times -4=0\\\\30\dfrac{dx}{dt}-160=0\\\\\dfrac{dx}{dt}=\dfrac{160}{30}=5.34\ ft/sec$

Hence, the ladder is sliding down the wall at a rate of $5\dfrac{17}{50}\ ft/sec$

Evaluate. 25/23 A) 1 B)28 C)4 D)8

Gwar [14]

25 divided by 23 will not come out as a whole number. 23 goes into 25 1 time so the answer would be 1..... But I guess the answer would be A since that's the closest answer choice.
