Answer:
The expression related pounds of each kind of meat you could buy at the store with $30 is .
Step-by-step explanation:
Given:
Total Money = $30
Cost of Roast beef per pound = $4.29
Cost of Turkey per pound = $3.99
Let Number of pounds Roast beef be x
Also Let Number of pounds Turkey be y
Hence the expression related to to the pounds of each kind of meat you could buy at the store with $30 is given by.
Total Money is equal to Cost of Roast beef per pound multiplied by Number of pounds Roast beef plus Cost of Turkey per pound multiplied by Number of pounds Turkey.
The mathematical form for above statement can be written as;
Hence the expression related pounds of each kind of meat you could buy at the store with $30 is .
Answer:
<em>Scale factor: 2</em>
<em>PR = 14</em>
<em>Perimeter = 34</em>
Step-by-step explanation:
<u>Similar Triangles</u>
Similar triangles are those who have their corresponding side lengths proportional, i.e. the ratio of the corresponding sides is equal.
The figure shows similar triangles ABC and PQR. We can also see corresponding sides BC and QR have lengths 6 and 12 respectively.
The scale factor is
The rest of the sides can be calculated by using the per-image triangle ABC side lengths and the new-found scale factor. Thus:
PR = AC*2 = 7*2 = 14
PR = 14
PQ = AB*2 = 4*2 = 8
The perimeter of the triangle PRQ is the sum of its side lengths:
P = 12 + 14 + 8 = 34
Answers:
Scale factor: 2
PR = 14
Perimeter = 34
