Answer:
The value of p at q = 5 is 406.25
Step-by-step explanation:
∵ p varies directly as the cube of q
→ That means p ∝ q³
∴ The equation of variation is p = kq³, where k is the constant of variation
∵ p = 26 when q = 2
→ Use them to find the value of k
∵ 26 = k(2)³
∴ 26 = k(8)
∴ 26 = 8k
→ Divide both sides by 8
∴ [tex]\frac{26}{8}=\frac{k}{8}[/tex]
∴ 3.25 = k
→ Substitute it in the equation of variation
∴ p = 3.25 q³ ⇒ equation of variation
∵ q = 5
→ Substitute it in the equation of variation to find p
∴ p = 3.25 (5)³
∴ p = 406.25
∴ The value of p at q = 5 is 406.25

1. James wants to buy snacks for his friends for a movie. The cost of one box of popcorn
is $3 and the cost of one soda is $2 but James only has $15 to spend. Write and
equation to represent this situation. Remember to define the variables!
2. If James buys 3 boxes of popcorn how many sodas can he buy?
Answer:
1.) 15-3-2=x
2.) He can buy 3 sodas
Step-by-step explanation:
1.) 15 is how much he has, -3 is the price of the popcorn, -2is the price of the soda. =x is what needs to be solved in the equation (its 10 if you need the answer)
2.) He can buy 3 sodas because 3 boxes of popcorn is $9 since one box is $3, he has $15 you take away $9 and you are left with $6 and 6 divided by 2 is 3.

Step-by-step explanation:
The total cost, C, to attend a swim meet for a swimmer competing in x events can be modeled using a linear function. Each swimmer will pay a $3.00 entry fee for each event and $8.00 for lunch. Each swimmer may sign up for a maximum of 5 events. What is the range of the function for this situation?
Answer:
The range is between $11 to $23Step-by-step explanation:
let the total cost be c
let the number of events be x
the linear model is
c=3x+8
therefore for 1 event
c=3(1)+8
c=3+8
c=11
=$11
therefore for 5 events
c=3(5)+8
c=15+8
c=23
=$23
The range is between $11 to $23

Jason had one hundred fifty-nine dollars to spend six books.After buying them he had fifteen dollars.How much did each book cost.
Answer:
11.5
Step-by-step explanation:
Divide: 159:6-15
Calculate: 26.5-15
\\11.5//
Answer:
24.8333 with 3 repeating.
Step-by-step explanation:
Lets make an equation for this.
159 - x = 15
X is what we are loooking for so lets isolate it.
Subtract 159 on both sides.
-x = -149
Since both are negative we need to simply cross it out.
x = 149
Now he bought six books, so divide 149 by 6.
You would get 24.8333 with the 3 repeating.

What value of p makes the equation true?
-3p + 1/8 = -1/4
Answer:
p = 1/8
Step-by-step explanation:
Hi there !
⁸⁾-3p + 1/8 = ²⁾- 1/4
- 24p + 1 = - 2
- 24p = - 2 - 1
- 24p = - 3 | (-)
24p = 3
p = 3⁽³/24

Step-by-step explanation:
Write the equation of the line fully simplified slope-intercept form.I need help with this so someone please answer this .
Answer:
y= -x+6
Step-by-step explanation:
The equation format for slope-intercept form is y=mx+c, where m is the slope of the line and c is the y-intercept.
To find the slope, we need to pick two definite points and find the slope from that. The formula to find the slope is 'rise/run'. Rise is the difference between the y-values of the two points, and the run is the difference between the x-values of the two points.
Let's use the points (0,6) and (1,5).
The rise is -1 (5-6=-1) and the run is also 1 (1-0=1). This means that the slope is -1 (-1/1=-1). The slope is negative because the line is 'going downwards'.
So our equation so far is:
y=-x+c
The y-intercept is where the line crosses the y-axis and the x-value is 0. We can see from the graph that the line crosses the y-axis at the point (0,6), therefore the y-intercept is 6.
So our final equation for the line is y= -x+6.

17 × 45 how to solve it
Answer:
765
Step-by-step explanation:
3
17 Multiply 7x5 and 1x5 first. 7x5=35, so we move the 3 above 1 and
x 45 add it to the product of 1x5. 1x5=5+3=8
85 Before we multiply 7x4 and 1x4, put a zero in the ones place.
+680 7x4=28, so we move the 2 above 1 and add it to the product of 1x4.
765 1x4=4+2=6 Add the products, and 765 is the answer!!

Kristen invests $5,000 in a bank. The bank pays 6% interest
compounded quarterly. Find, to the nearest cent, the balance
in the account after 5 years. To the nearest year, how long
must she leave the money in the bank for it to double?
Answer:
1. ) $6,734.30
2) 12 years
Step-by-step explanation:
1. we use the compound interest formula for this
Mathematically;
A = P( 1 + r/n)^nt
where P is the principal which is the amount deposited = $5,000
r = rate = 6% = 6/100 = 0.06
n = number of time per year we compound = 4 since it is quarterly
t = number of years = 5
Substituting all of these, we have;
A = 5,000( 1 + 0.06/4)^(4)(5)
A = 5,000( 1 + 0.015)^20
A = 5,000(1.015)^20
A = $6,734.28 which to the nearest cent = $6,734.30
2) For the money to double means that A becomes 2P
Thus;
2P = P( 1 + 0.015)^4t
divide both sides by P
2 = (1.015)^4t
Fine the ln of both sides
ln 2 = 4t ln 1.015
divide both sides by ln 1.015
4t = ln 2/ ln 1.015
4t = 46.56
t = 46.56/4
t = 11.63 which is approximately 12 years
