Answer:
Undefined slope.
Step-by-step explanation:
The formula should be y2 - y1 over x2 - x1
Points ( 20,-16 ) and ( 19, -16 )
So ( -16 - ( -16 ) ) over ( 19 - 20 )
0 over -1
The slope is 0. Undefined.
Answer:
20.875
Step-by-step explanation:
18+24+17+21+24+16+29+18=167/8=20.875
Answer:
$42.12
Step-by-step explanation:
35% off means she has to pay:
100 - 35 = 65% of the marked price.
65/100 × 60 = 39
Tax: 8%
8/100 × 39 = 3.12
To pay:
39 + 3.12 = 42.12
Answer:
The mass of the object is 2.6 grams
Step-by-step explanation:
The density of an object is the ratio between its mass and its volume
The equation of the is d =
, where
Let us use this equation to solve the question
∵ An object has a density of 1.3 g/cm³
∴ d = 1.3 g/cm³
∵ Its volume is 2 cm³
∴ V = 2 cm³
→ Substitute them in the equation of the denisty above
∵ 1.3 = ![\frac{m}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bm%7D%7B2%7D)
→ Multiply both sides by 2
∴ 2 × 1.3 = 2 × ![\frac{m}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bm%7D%7B2%7D)
∴ 2.6 = m
∴ The mass of the object is 2.6 grams
