In this case, the straight vertical side of Figure A is 6 units, and the straight vertical side of Figure B is 2. So 6 divided by 2 is 3. That means that the scale factor of the triangle is of 3.

5. A 12-ounce jar of jam costs $2.40. A 16-ounce jar costs $4.00. What is the
scoray [572]

The difference in the cost per ounce is $0.05 per ounce

<h3>Fractions and proportion</h3>

Fractions are written as the ratio of two integers

If a 12-ounce jar of jam costs $2.40, the cost per ounce will be:

Unit cost = 2.40/12

Unit cost = $0.2

Similarly, if a 16-ounce jar costs $4.00, the price of a ounce will be:

Unit cost = 4/16

Unit cost. =$0.25

difference = $0.25 - $0.2

difference = $0.05

Hence the difference in the cost per ounce is $0.05 per ounce

Step-by-step explanation:

Question not written well

The equation of the ball is meant to be in a parabola or trajectory form.

So, h = -4.912t² + 24.5t + 1

The ball will hit the ground when the height is 0

I.e. h= 0

Therefore,

-4.912t² + 24.5t + 1 = 0

Using almighty formula,

a = -4.912 b = 24.5 c = 1

t = (-b±√b²-4ac) / 2a

t = (-24.5±√24.5²-4×-4.912 × 1) / 2 × -4.912

t = (-24.5±√600.25 + 19.648) / 9.824.

t = (-24.5 ± 24.898) / 9.824

So,

t = (-24.5 + 24.898) / 9.824

t = 0.398 / 9.824

t = 0.04seconds

Or

t = (-24.5 - 24.898) / 9.824

t = -5.03 seconds

So, we are going to discard the negative time,

t = 0.04 second is the correct time the ball will hit the ground
