Geometry help please? Find the variable

True [87]3 years ago

So if your doing #14, then this is trying to find what x,y,and z are. The way to find this knowing that a triangle is always 180 degrees. If a triangle is always 180 degrees, then that means that the right triangle is 54 degrees + the other two points, which will add up to 180. The box on the bottom left of the right triangle is showing that this angle is a right angle, meaning it's 90 degrees. So you have 90 degrees plus 54 degrees, which equals to 144 degrees. This isn't 180, so what number is needed to make it 180? 36 degrees is the answer, because if you have 54+90+ y= 180 then you find y, 144+y=180, what's y? 36 degrees is y to make it 180 degrees. The same is for the left triangle. Z is the same angle as the right angle on the right triangle, so z is 90 degrees. So we have the problem 52+90+x= 180, meaning 142+x=180. X is 38 degrees, because that is the number needed to make the triangle 180 degrees. So you have y= 36 degrees, x= 38 degrees, and z= 90 degrees. Hope this helps

Can someone tell me if i got this right? its all i need
Alexxx [7]

Answer:

No, the answer is 120 plants per square foot

Step-by-step explanation:

What I did was first figure up the area of the triangle. You want to do this because the area will tell you how many square feet are in the garden. In order to find this, you need to use this formula: 1/2 b·h

Plug in the numbers like this: 1/2·15·8

15 is the base of the triangle, while 8 is the height of the triangle. Now solve your equation.

15·8=120

1/2·120=60

Area = 60

Now you know that the area is 60ft². So there are 60 square feet in the whole garden. But, we're not done yet. Jessica wants to put 2 plants in every 1 square foot. So now, we need to multiply 60 by 2 in order to get 2 plants in every 1 square foot.

60·2=120

Jessica can put 120 plants in the garden if she is wanting 2 plants per square foot.

I hope this makes sense and is easy to understand. Please let me know if you need any more help or clarification. I'm always happy to help! Have a great day and good luck!!

irakobra [83]

Answer:

5 1/3 hours.

Step-by-step explanation:

Ashley prepares 1 bag in 2/3 minutes.

One friend takes 2/3 + 3/4 * 2/3 = 7/6 minutes to make 1 bag.

4 of her friends can make 1 bag in 7/6 * 1/4 = 7/24 minutes.

If it takes x minutes for  Ashley and 4 friends to make one bag then we have:

1 / 2/3  + 1 / 7/24 = 1 / x

3/2 + 24/7 = 1/x

Multiply through by 14x:

21x + 48x = 14

x = 14/69 minutes.

So the  time to make 1575 bags = 1575 * 14/69

=  320 minutes.
