All you have to do is make a equation. Which would be p5+3 =v  the answer should be 8 because if you plug 8 in you get (8)5+3=v  40+3= 43 then you add 8 to 43 and get 51 so i believe the answer to your question is 8

Answer: There are 8 pepperoni pizzas she order.

Step-by-step explanation:

Since we have given that

Number of vegetable pizzas and pepperoni pizzas for the eighth grade party = 51

Let the number of pepperoni pizzas be 'p'.

Let the number of vegetable pizzas be 'v'.

According to question,

v=5p+3

So, it becomes,

v+p=51\\\\5p+3+p=51\\\\6p+3=51\\\\6p=51-3\\\\6p=48\\\\p=\dfrac{48}{6}\\\\p=8

Hence, there are 8 pepperoni pizzas she order.

One hundred grams of radium are stored in a container. The amount RR (in grams) of radium present after tt years can be modeled
drek231 [11]

Answer:

6967 years

Step-by-step explanation:

Given the exponential function :

R=100e−0.00043t

Time = t in years

R = final amount

Number of years in which only 5 grams of radium will be present :

R = 5

Plugging into our formula :

5 = 100 * e^−0.00043t

5 / 100 = e^−0.00043t

0.05 = e^−0.00043t

Take the In of both sides

−2.995732 = - 0.00043t

t = −2.995732 / - 0.00043t

t = 6966.819

t = 6966.819 years

t = about 6967 years
