Answer: Veronica spent $26.8
Explanation:
5 x $1.79= $8.95
15 x $1.19= $17.85
$8.95 + $17.85= $26.8
A volcano is an inverted cone and with that, the volume can be solved through the equation,
V = (1/3)(area of the base)(height)
We solve the area of the base first,
area of the base = (pi)(r²)
= 3.14(6 in)²
= 113.04 in²
Substituting these calculated values and the other givens above to the first equation,
V = (1/3)(113.04 in²)(12 in) = 452.16 in³
Thus, the volume of the model is approximately equal to 452.16 in³.
Answer:
90/1.5=60 mph
Step-by-step explanation:
I assume that the train is traveling at constant speed.
Between 12:45 pm and 2:15 pm the train has traveled 180-90=90 miles. So 90 miles in 1.5 hours which means that its speed is 90/1.5=60 mph
Answer: 8
<u>Step-by-step explanation:</u>
The formula for the sum of the angles of a polynomial is:
1080 = 180(n - 2)
1080 = 180n - 360
1440 = 180n
8 = n
