Answers
Question:
An hour before show time, only 155 people are seated for rockfest. According to the ticket sales, 95% of the people have yet to arrive. How many tickets were sold?
Answer:
3100 tickets
Step-by-step explanation:
Given
[tex]p = 95\%[/tex] --- Yet to arrive
[tex]Seated = 155[/tex]
Required
Determine the total number of people
If 95% are yet to arrive, then 5% have arrived (i.e. 100% - 95%)
So, the total number of people is calculated as:
[tex]5\% * x = 155[/tex]
Where x represents the total number of tickets
Make x the subject
[tex]x = \frac{155}{5\%}[/tex]
[tex]x = \frac{155}{0.05}[/tex]
[tex]x = 3100[/tex]

A fossil contains 19% of the carbon-14 that the organism contained when it was alive. Graphically estimate its age. Use 5700 years for the half-life of carbon-14.
The fossil is approximately _years old.
(Round to the nearest integer as needed.)
Answers
.5=e^5700k
To figure out k here take the natural log of both sides:
ln(.5)=5700k
Then solve for k:
k=ln(.5)/5700 ~~ -1.216*10^-4
Now that we know what k is, we can go back to the original question and plug in everything we know! Our new equation should look like this:
.04=e^((ln(.5)/5700)t)
Solving for t works the same as solving for k, take the natural log of both sides:
ln(.04)=(ln(.5)/5700)t
Then solve for t:
t=ln(.04)/(ln(.5)/5700) ~~ 26469.98 years

Answers
Answer:
A. Y-68=-5(x-14)
Step-by-step explanation:
Mary is spending money at the average rate of $5 per day. After 14 days she has $68 left. The amount left depends on the number of days that have passed. write an equation for the situation
We find the equation using the point slope equation of a line. This is given as:
y - y1 = m(x-x1)
The slope intercept form will be
y = -5x + b
since the amount decreases by $5 per day...
Our slope is -5 so m=-5
We have a point (x1,y1) = (14, 68)
Hence, we have:
y-68 = -5(x-14)

6 is the given width at the top and because it’s a parallelogram, that means the bottom is equal to 6 as well. So that makes the base 6 units. The formula to find the area of a parallelogram is b x h and because you’re given two values, you just plug them into the formula and solve for the missing one. You’ll get 24 = 6 x h. You can solve this by dividing both sides by 6 and you’ll end up with h = 4.

Answers
Answer:
Step-by-step explanation:
Simplifying
10 = 4y
Solving
10 = 4y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-4y' to each side of the equation.
10 + -4y = 4y + -4y
Combine like terms: 4y + -4y = 0
10 + -4y = 0
Add '-10' to each side of the equation.
10 + -10 + -4y = 0 + -10
Combine like terms: 10 + -10 = 0
0 + -4y = 0 + -10
-4y = 0 + -10
Combine like terms: 0 + -10 = -10
-4y = -10
Divide each side by '-4'.
y = 2.5
Simplifying
y = 2.5
Rachel bought 15 packs of colored pencils with four pencils in each pack. She also
bought 32 packs of glitter pencils with two pencils in each pack. Write and evaluate an
expression to find the total number of pencils she bought.
Answers
Answer:
124
Step-by-step explanation:
15 x 4=60
32 x 2=64
64+60=124
Rachel bought a total of 124 pencils.
What is a numerical expression?A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.
To find the total number of colored pencils Rachel bought, you can multiply the number of packs she bought by the number of pencils in each pack. Since she bought 15 packs of colored pencils with four pencils in each pack, the expression would be:
15 packs × 4 pencils/pack = 60 pencils
To find the total number of glitter pencils Rachel bought, you can use the same process. Since she bought 32 packs of glitter pencils with two pencils in each pack, the expression would be:
32 packs × 2 pencils/pack = 64 pencils
To find the total number of pencils Rachel bought in total, you would add the number of colored pencils to the number of glitter pencils. The expression would be:
60 pencils + 64 pencils = 124 pencils
Hence, she bought a total of 124 pencils.
