Step-by-step explanation:
Hey there! :)
Answer:
16 minutes.
Step-by-step explanation:
Create an equation in the form y = mx + b to solve this problem. Begin by solving for the rate of change of the table using the slope formula:
Plug in values from the table into the equation:
Simplify:
m = 6.
Plug in the slope and a point from the table into the equation
y = mx + b
40 = 6(5) + b
40 = 30 + b
40 - 30 = b
b = 10.
Rewrite the equation:
y = 6x + 10
To solve for how long it took her to ride 1 km, plug 1 into the equation:
y = 6(1) + 10
y = 6 + 10
y = 16 minutes.
Answer:
C. x + 5 = (x + 5) − 5, which has no solution
Step-by-step explanation:
Jenna's age Jessica's age
today x x + 5
in 5 years x+5
5 years ago x + 5 - 5
Equality x + 5 = x + 5 - 5
=> x + 5 = x
The equation is x + 5 = ( x + 5 ) -5
V=4/3pi(r^3)
V=4/3pi(9^3)
V=3,054 inches^3
Think this is right
Answer with Step-by-step explanation:
A candle is 4 inches tall and burns at the rate of 0.6 inch per hour.
i.e. after 1 hour height of candle=4-0.6 inches
After 2 hours height of candle=4-0.6-0.6 inches
after x hours height of candle=4-0.6x
Also,
If the height of the candle after x hours is 1.5 inches
⇒ 4-0.6x=1.5
⇒ 0.6x=4-1.5
⇒ 0.6x=2.5
⇒ x=2.5/0.6
⇒ x=4.166
Hence, equation to represent the situation. is:
4-0.6x=1.5
and the expected number of hours in which the candle melted to 1.5 inches is:
4.166 hours
