A box weighs 90 grams.Write down in terms of b ,the weight of b boxes
iogann1982 [59]

Let B = the weight of box B

Let 2B = the weight of box A

Let 2B + 30 = the weight of box C

B + 2B + 2B + 30 = 640

5B = 610

B = 122 pounds, weight of box B

2B = 2(122) = 244 pounds, weight of box A

2B + 30 = 2(122) + 30 = 274 pounds, weight of box C

hope this helps

PLEASE HELP OMG the side lengths of triangle MNO are given: MN=5, NO=4, OM=2.5. the triangle is dilated by a scale factor of k w
elena-14-01-66 [18.8K]

The value of the scale factor k, is 1.5

<h3>Perimeter</h3>

The perimeter of a shape is the sum of the side lengths of the shape

<h3>Dimensions </h3>

The dimensions of the triangle MNO are given as:

MN = 5

NO = 4

OM = 2.5

Calculate the perimeter of the triangle as follows:

MNO=5 + 4 +2.5

MNO=11.5

Divide 17.25 by 11.5 to calculate the scale factor (k)

k = \frac{17.25}{11.5}

k = 1.5

Hence, the scale factor is 1.5
