Answer:

42 minutes

Step-by-step explanation:

70% x T = 98

7T/10 = 98

7T = 980

T = 140 mins

140 - 98

= 42 minutes

Answer: 42 mins

Step-by-step explanation: 70% / 7 x 3 = 98 / 7 x 3 = 14 x 3 = 42 minsDivide 70% by 7 to find 10%. Subtract 70 from 100 equals 30, so multiply 10 by 3 to find the remaining 30%.

I'm really stuck on this math problem. I never learned this in school. Can someone please help me out? Thank you
romanna [79]
Hehe, these are fun to do. There are two ways to do this kind of problem. You can use the pythagorean theorem or we can use the distance formula.
Distance formula:
d= \sqrt{(x2-x1)^2+(y2-y1)^2}

Pythagorean Theorem:
a^2+b^2=c^2

Distance formula is better if you're finding distance between two coordinates. The Pythagorean Theorem only really works for independent values. If I had 2 sides of a triangle, and I needed to find the third, I'd use this equation to find it. In this case, we'll use the distance formula.

I'll work the first one out for you:
 x1   y1     x2  y2  
(3,   2) & (7,   4)

d= \sqrt{(7-3)^2+(4-2)^2}
                           v
d= \sqrt{(4)^2+(2)^2}
                           v
d= \sqrt{(16+4}
                           v
d= \sqrt{20}

There's your answer!

Which polyhedron is represented by the net shown
irina1246 [14]

Answer:

triangular pyramid

Step-by-step explanation:

Let's make the central triangle the "base", or the bottom face, of our polyhedron. Try to visualise what will happen if we fold up the three triangles so that their top vertices meet at the center top (see diagram).

If we can do that, we'll see that it's a pyramid with a triangular base, so it's a triangular pyramid.
