If a bottle rotates through 250 degrees in 50 min,how many degress will it rotate in 5 min

1 answer:

3 0

There is more than one way to solve this.
250° : 50min.
You can divide each side by ten for 5 minutes.
50/10 = 5 minutes
250/10 = 25°

Last winter Armand had StartFraction 5 Over 6 EndFraction of a row of stacked logs. At the end of the winter, he had StartFracti

Nataly_w [17]

Answer:

3/10

Step-by-step explanation:

According to the Question,

Given, Last winter Armand had 5/6 of a row of stacked logs & At the end of the winter he had 8/15 of the same row left.

Now, First We have to make the Fraction even so their denominators must have to be equal.

So. 15×2 = 30(denominator), Multiply with numerator too 8×2=16.

And, 6× 5 = 30(denominator), Multiply with numerator too 5×5=25.

Now. We get New Ratio's now with equal denominator, We can say that

⇒Armand had 25/30 of a row of stacked logs & At the end of the winter he had 16/30 of the same row left.

So, on Simply we get (25-16)/30 ⇒ 9/30 ⇒ 3/10 Wood he burns Over the winter.

If using the method of completing the square to solve the quadratic equation x^2 -4x +10 =0, which number would have to be added

Delvig [45]

Answer:

4 would have to be added to complete the square.

Step-by-step explanation:

We are given the following quadratic equation the question:

$x^2 -4x +10 =0$

We have to form a whole square to solve the quadratic equation.

$x^2 + ax + b\\=(x+c)^2+d\\\text{where}\\\\c = \dfrac{a}{2}$

We add and subtract the square of the coefficient of x.

$x^2 -4x =-10\\x^2 -4x + 4=-10+4\\(x-2)^2=-6\\x-2 =\pm \sqrt{6}i\\x = 2+\sqrt6i , 2-\sqrt6i$

Thus, we added and subtracted 4 in the quadratic equation to make it a complete square.

How to do this question plz answer me step by step plzz

finlep [7]

Answer:

30, 85, 95, 150

Step-by-step explanation:

The angles of a quadrilateral add to 360

Let x be the smallest angle

x+55

x+65

x+120 are the other three angles

Add the 4 angles together and they sum to 360

x+x+55 x+65+ x+120 = 360

Combine like terms

4x+240 = 360

Subtract 240 from each side

4x+240-240 = 360 -240

4x = 120

Divide by 4

4x/4 = 120/4

x = 30

x+55= 30+55 = 85

x+65 = 30+65 = 95

x+120 = 30+120 = 150

Svetlanka [38]

Answer h=-80
vvv STEP BY STEP vvv
Multiply both sides of the equation by
52-h=28

Move constant to the right-hand side and change its sign
-h=28+52

Add the numbers
-h=80

Change the signs on both sides of the equation
h=-80
