Try this option (<u>not for all the tasks!</u>):
1) rule for n-angle is: S=180°(n-2), where n - number of the sides. S₁₅=180*13=2340°;
2) S₂₅=180*23=4140°;
4) this is deltoid;
5) this is paralelogram;
6) x=130°; y=50°;
10) x=90°; y=30° (it is deltoid);
12) not enough info for parallelogram (the same for deltoid);
14) it is enough: according to a property of a parallelogram (it means that a square and rombus are parallelograms);
15) it is enough according to the properties of parallelograms;
16) x=2; y=1;
18) poit S(0;0); point T(b+c;d). The coordinates of the midpoint are (0.5b+0.5c;0.5d); slope=arctg(d/(b+c)).

That’s not enough information to say how long he could do it. He could go slower or faster than her but by how much if so. So it’s not enough info.

You order plant seeds from a catalog. Each packet cost 0.90 each. The shipping charge is 2.50. If you have 18.50 to spend, how m
kramer
<h2>Answer:</h2>

17

<h2>Step-by-step explanation:</h2>

Cost per Packet * Number of Packets + Shipping =  Amount to Spend

0.90 * b + 2.50 = A

You can spend a maximum of $18.50

A < 18.50

Rearrange the formula to find b

Number of Packets  =  Amount to Spend - Shipping / Cost per Packet

18.50 - 2.50 = 16.00 / 0.9 = 17.7...

You can't have 0.7 of a packet so you have to round down to 17.

Now if you put it into the original formula:

0.90 * 17 + 2.50 = 17.80

And 17.80 is less than 18.50.
