I think it would be x > 2 because if you subtract 2 from 2 and 12 the 2 disappears and then you have 10 and 5 Divided by 10 = 2.

It would be the first box, when multiplying exponents, you add the exponents and just keep the base. So it be 2^17

The ratio of the perimeters of two similar triangles is 4:7. The sides of the larger triangles are 10, 12, and 13cm,

rjkz [21]

Answer:

Perimeter = 20cm

The perimeter is 35 for the larger triangle = 7:4 ratio

the perimeter for the smaller triangle = 4:7 ratio

We add up 4+7 = 11 and multiply 35 x 2 = 70.

so that the smaller triangle = 40 = 40:70

35 = 7 and 20 = 4

To find measurements of 20

we have any number over 10 combined will make the smaller sides possible,

Where hypotenuse would be under 10.

H = 6.5 Sides = 6 + 5 does not add up to 20

H = 9 Sides = 7 + 4 does have near equal spaced symmetry.

H = 9 Sides = 5 + 6 is wrong as no symmetry in measure

H = 8 Sides = 7 + 5 is wrong as no symmetry in measure

H = 7 Sides = 6 + 7 is wrong as equal sides

H = 6 sides = 6.5 + 6.5 is wrong as equal sides

H = 11 Sides = 6 + 3 is wrong has no symmetry.

The measurements must be 9cm, 7cm and 4 cm for the smaller triangle

The perimeter adds up to 20cm.

2. Ms.A buys 7 boxes of snacks. Each box has 12 packets of fruit snacks and 18 packets of cashews.

timurjin [86]

Answer: 210

Explanation:

Each box has 12 packets of fruit snacks and 18 packets of cashews. That gives 12+18 = 30 packets overall per box. Since we have 7 boxes, that tells us the total count is 7*30 = 210

The amount of paint that David needs to cover a cube is directly proportional to the surface area. If David can completely cover

Inessa05 [86]

Answer:

The cube must be 21.125 feet long.

Step-by-step explanation:

David can completely cover a cube of side length equal to 2 feet, using 16 quarts of paint.

With this we make a conversion factor:

$\frac{2}{16}$ feet/quarts = 0.125 feet/quarts

This means that with each quart of paint you can paint a 0.125-foot long cube

We need to know how big is the length of a cube that can be covered with 169 quarts of paint

Then we use the conversion factor found earlier

$\169quarts * \frac{2pies}{16quarts} = 21.125 feet.$

The cube must be 21.125 feet long.
