Answer 1

Step-by-step explanation:

Using Pythagoras theorem,

Let the ratio of the sides be x

B²=H²-P²

B²= (25x)²-(21x)²

B²=625x²-441x²

B²=184x²

B=13.56x.

hope this helps you.

Answer 2

Answer:

Your answer is [tex]\sqrt{184}[/tex] or 13.5646599663...

Step-by-step explanation:

[tex]A^{2} +B^{2} =C^{2} \\A^{2} +21^{2} = 25^{2} \\A^{2} = 25^{2} - 21^{2} \\A^{2} = 625-441\\A^{2} = 184\\A = \sqrt{184}[/tex]

Hope this helps!

andwer? 6.11#16 yan po

Answer:

6 11/15

Step-by-step explanation:

So the equation is 6 9/10 - 1/6, you gotta have similar denominators to have an easy subtraction process. So 9/10 - 1/6. Both numbers go into 60. 10×6 so that becomes the new denominator. Now your numerator, the 9 is times 6 because the 10 gets times by 6 so 9 times 6 = 54. You got your first fraction done and you put I back with the whole number so 6 54/60. So 1/6 10 times 6 equals 60 so now 1/60 times the 1 by 10 whatever you do to the bottom you do to the top 1 times 10 is 10 so we got out second fraction 10/60 so now it's 6 54/60 - 10/60, 54 - 10 = 44 so your answer is 6 44/60 but we can simplify so 44 ÷ 2 = 22 and you do it to the bottom 60 ÷ 2 = 30 now we got 22/30 we can divide by 2 again and we get 11/15. Put it back with the whole number and we get 6 11/15

Consider triangle ABC where AB=X+5, BC=X-2, area is 30cm squared. Find X by solving X^2+3X-70=0, and find the perimeter.

Answers

Answer:

What the hell AC is not given so you can't find the Perimeter

Step-by-step explanation:

x^2+3x-70=0(x-7)(x+10)=0x-7=0

       x+10=0

x=7

       x=-10

AB=x+5

AB=12

        AB=-5

BC=x-2

BC=5

        BC=-12

Area of ABC = 30cm2

Perimeter of ABC = AB+BC+AC

which is an equation of the line with a slope of 1/4 and a y-intercept of -2?

Answers

Answer:

y = 1/4x -2

Step-by-step explanation:

If the slope is 1/4, then you must multiply x by 1/4. If we plug 0 into 1/4x, we get 0, but we need -2, so we must subtract 2 in the equation.

Leila runs at 12 miles per hour. Find the number of miles she can travel if she runs for 3 more than t hours.

Answers

Answer:

If she runs for three hours, then she'll run 36 miles

Going at the speed she is going, Leila can travel a distance of 12(3 + t).

The distance that a person can travel is found by:

= Speed x time

The speed here is 12 miles per hour

Time = 3 more than t hours = (3 + t hours)

The distance Leila would have gone is therefore:

= 12 x (3 + t)

= 12 (3 + t)

In conclusion, as the question is not complete, the relevant expression to find the distance is 12 ( 3 + t)

Find the unknown sizes of angles:​

Answers

First we find X:
3x+x=180
4x=180
x=180/4
x=45.

3x=135

135+y=180
y=180-135
y=45

45+z=180
z=180-45
z=135

In conclusion, x=45, 3x=135, y=45 and z =135

Also note that the opposite angles are equal so you can just find 3x and that will be equal to z and x will be equal to y.

Hope this helped

Step-by-step explanation:

We have ,

x = y ( vertically opposite angles ) 3x = z ( ,, )

As we know ,

Complete angle = 360° x + y + 3x + z = 360° x + x + 3x + 3x = 360° 8x = 360° x = 45°

Hence ,

x = 45° y = x = 45° z = 3x = 45*3 = 135° 3x = 135°.

Do u think temperature and pressure have any effect on gasses ​

Answers

Answer:

Gay Lussac's Law - states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. If you heat a gas you give the molecules more energy so they move faster. This means more impacts on the walls of the container and an increase in the pressure.

Step-by-step explanation: An increase in the number of gas molecules in the same volume container increases pressure. A decrease in container volume increases gas pressure. An increase in temperature of a gas in a rigid container increases the pressure

Answer:

yes I think that temperature makes it hotter or

colder depending on the temperature of it or the surroundings and the pressure I don't honestly don't think it effects them
