Answer:
6.49 × 10⁷ years
Step-by-step explanation:
For Dinosaurs
Dinosaurs have been extinct for about 6.5×10 exponent seven years
6.5 × 10⁷ years
For Neanderthals
Neanderthals have been extinct for about 3.0×10 exponent four years
= 3.0 × 10⁴ years
How many longer is calculated by Subtraction
6.5 × 10⁷ years - 3.0 × 10⁴
= 64970000 years
= 6.49 × 10⁷ years
56 772
- 34 895
= 21 877
Rounds off to
22 000
Answer:
x = -28
Step-by-step explanation:
x-(-5) = x + 5
x + 5 = -23
-23 - 5 = -28
x = -28
a constant of proportionality is a number you have to multiply x by to get y.
y=kx is the equation that expresses the proportionality of x and y
in this case, 10 video games cost $145
the question's basically asking what you have to multiply 10 by to get 145
y= 145; x=10
k= y/x = 145/10=14.5
the constant of proportionality is 14.5
Answer:
The formula to calculate the total surface area of a cylinder is given as, the total surface area of cylinder = 2πr(h + r), while the curved surface area of cylinder formula is, curved/lateral surface area of cylinder = 2πrh, where 'r' is the radius of the base and 'h' is the height of the cylinder.
