I thought of a two-digit number. The unit digit of my number is 7 more than the tens digit cubed. What is my number?
Answer:
18.
Step-by-step explanation:
If the tens digit is x^3 the unit digit is x^3 + 7
So 10 * x^3 + x^3 + 7 < 100 (as its a 2 digit number).
11x^3 < 93
x^3 < 8 5/11
x < 2.04
As x must be an integer it is either 1 or 2.
It cannot be 2 as 2^3 = 8 and 8+7 = 15 which cannot be the tens digit so it must be 1.
The answer is 1 and (1+7) = 18.
Answer:
18.
Step-by-step explanation:
If the tens digit is x^3 the unit digit is x^3 + 7
So 10 * x^3 + x^3 + 7 < 100 (as its a 2 digit number).
11x^3 < 93
x^3 < 8 5/11
x < 2.04
As x must be an integer it is either 1 or 2.
It cannot be 2 as 2^3 = 8 and 8+7 = 15 which cannot be the tens digit so it must be 1.
The answer is 1 and (1+7) = 18.

Suppose that a tea company estimates that its monthly cost is C(c) = 500x² + 100x and its monthly revenue is R(2) = -0.6x3 + 700x2 – 400x + 300, where x is in thousands of boxes of tea sold. The profit is the difference between the revenue and the cost. What is the profit function, p(X)?
O A. P(x) = 0.6x3- 200x2 + 500x+ - 300
OB. P(x) = -0.6x3 + 1200x2 – 300x + 300
O C. P(x) = -0.6x3 + 200x2 – 500x + 300
D. P(xl = 0.6x3 + 200x2 – 500x + 300
Answer:
p(x) = 0.6x³ - 200x² + 500x- 300
Step-by-step explanation:
Given the cost function and revenue function as:
C(x) = 500x² + 100x
R(x) = -0.6x³ + 700x² – 400x + 300
To get the profit function:
p(x) = C(x) - R(x)
p(x) = 500x² + 100x -(-0.6x³ + 700x² – 400x + 300)
open the parenthesis
p(x) = 500x² + 100x + 0.6x³ - 700x² + 400x - 300
p(x) = + 0.6x³+500x² - 700x² + 100x+ 400x- 300
p(x) = 0.6x³ - 200x² + 500x- 300
Hence the profit function is expressed as p(x) = 0.6x³ - 200x² + 500x- 300

Step-by-step explanation:
Andy is scuba diving. He starts at sea level and then descends 10 feet in 212 minutes.
Descent = 10 feet
Time required = 2 1/2 minutes.
The rate of descent = (10 feet)/(2.5 mn) = 4 ft/min
In 6 minutes, the descent will be
(4 ft/min)*(6 min) = 24 ft
Answer:
(a) 4 feet/minute
(b) 24 feet
The farmer decided that he ordered enough planks for an arena that measured 115 1/4 ft by 63 1/2 ft. Is he correct? Explain.
What questions do you need to answer this question? Please help
Answer:
The question we need to answer is what is the perimeter of the arenaStep-by-step explanation:
The question we need to answer is what total length of plank did the farmer ordered for the arena.
to solve for the length of plank to cover the arena we need to solve for the perimeter of the arena.
given data
length L= 115 1/4 ft = 115.25ft
width W= 63 1/2 = 63.5ft
perimeter= 2L+2W
perimeter= 2(115.25)+2(63.5)
perimeter= 230.5+127
perimeter= 357.5ft
This means that the farmer ordered a total length of 357.5ft of plank
R is the midpoint of segment PS. Q is the midpoint of segment RS. P is located at (8,10), and S is located at (12,-6). What are the coordinates of Q
Answer:
(10,2)
Step-by-step explanation:
To find the midpoint you have to:
Add both "x" coordinates then divide by 2. 12+8=20 20/2=10
Add both "y" coordinates then divide by 2. 10+(-6)=4 4/2=2

Convert to a fraction: 0.18
Answer:
9/50 = 0.18
-----------------------------------------
Convert decimal to fraction
0.18 = 18 over 100
18/100
Simplify
18 over 100
= 9 over 50
9/50, Reduce fraction to lowest terms.
18/100 = 18 divided by 2 over 100 divided by 2 = 9 over 50

Step-by-step explanation:
The mean mass of the 15 players in a rugby team is 85.2kg the mean mass of the team plus a substitute is 85.4kg what is the mass of the substitute ?
Answer:
88.4 kg
Step-by-step explanation:
Since we are given the mean we will need to multiply the mean by how many players there are on the team to find the total mass. (The second mean will be multiplied by 16 because it is the number of players on the team plus the substitute)
85.2 x 15 = 1,278
85.4 x 16 = 1,366.4
Subtract the first mass from the second because this will remove the mass of the 15 other players.
1366.4 - 1278 = 88.4
88.4 kg is the mass of the substitute.

24. Critical Thinking Anika wants to determine the maximum
number of tulip bulbs (t) she can purchase if each bulb costs $1.50.
She will also need to purchase separate pots for each bulb at $1.25
each and a bag of potting soil for $10.00. Set up an inequality to
determine how many tulip bulbs Anika can purchase without
spending more than $20.00, and solve it. Can Anika buy exactly
enough bulbs and pots to spend the full $20.00? Explain. Can you
think of a better inequality to describe the answer?

What is the maximum height of the triangle?
Klein
Tanis
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Cost per bulb = $1.50
Cost per pot = $1.25
Bag of potting soil = $10.00
Budgeted amount to spend ≤ 20
Cost :
Bag of potting soil + (Cost per bulb + cost per pot)*number of tulip bulbs ≤ 20
$10 + ($1.50 + $1.25)t ≤ $20
$10 + 2.75t ≤ 20
$2.75t ≤ $20 - $10
$2.75t ≤ $10
t ≤ $10/$2.75
t ≤ 3.636
Hence, t = maximum number of tulip bulbs she can purchase is 3.636,
Since the exact number of tulip bulb she can purchase is a decimal which is impossible in an actual scenario. Hence, In other to spend not more than $20.00
t ≤ 3
explain why the quadratic relation y=2x^2+3x+5 would have no zeros
Complete the square to rewrite the quadratic:
2 x² + 3 x + 5 = 2 (x² + 3/2 x) + 5
... = 2 (x² + 3/2 x + 9/16 - 9/16) + 5
... = 2 (x² + 3/2 x + (3/4)²) + 5 - 9/8
... = 2 (x + 3/4)² + 31/8
Any real number squared becomes non-negative, so the quadratic expression has a minimum value of 31/8, which is greater than 0, and so there are no (real) x for which y = 0.

Use the GCF and the distributive property to express the sum as a product 35+25
Answer:
5(5+7) = 5(5) + 5(7)Step-by-step explanation:
Given the expression 25+35.
Given A, B and C, according to distributive property:
A(B+C) = AB + BC
A is distributed over B and C where A is the GCF in this case. Applying this in the expression given
25 = 5 * 5
35 = 5* 7
25+35 = (5*5)+(5*7)
25+35 = 5(5+7)
5(5+7) = 5(5) + 5(7) (Distributive property)
Use the work shown below to find the simplified product.

Answer:
a. [tex]\frac{5x}{(x+3)}[/tex]
b. [tex]\frac{5x}{(x+3)}[/tex]
Step-by-step explanation:
Given that:
a. [tex](\frac{25x^{2} }{2x+6})[/tex] x [tex](\frac{2}{5x})[/tex] = [tex]\frac{50x^{2} }{5x(2x+6)}[/tex]
= [tex]\frac{50x^{2} }{10x^{2} +30x}[/tex]
= [tex]\frac{(50x)x}{(10x+30)x}[/tex]
= [tex]\frac{50x}{(10x+30)}[/tex]
= [tex]\frac{5x}{(x+3)}[/tex]
b. [tex](\frac{25x^{2} }{2(x+3)})[/tex] x [tex](\frac{2}{5x})[/tex] = [tex]\frac{50x^{2} }{10x(x+3)}[/tex]
= [tex]\frac{5x}{(x+3)}[/tex]
Therefore,
[tex](\frac{25x^{2} }{2x+6})[/tex] x [tex](\frac{2}{5x})[/tex] = [tex](\frac{25x^{2} }{2(x+3)})[/tex] x [tex](\frac{2}{5x})[/tex] = [tex]\frac{5x}{(x+3)}[/tex]

Ruby is moving from Minneapolis to Chicago, which is 400 miles away. She is traveling at an average speed of 50 miles per hour. Ruby stops for gas after a couple of hours and wonders how much further she needs to go. If y represents distance and x represents time, which linear equation would indicate the amount of miles Ruby still has to travel to Chicago?
Answer:
y = 400 - 50x
Step-by-step explanation:
From Minneapolis to Chicago = 400 miles
Speed of travel = 50 miles per hour
y = distance ; x = time
Distance = speed * time
Distance moved before stopping for gas:
50 * x = 50x
y = distance left to cover ;
400 m = total distance
50x = distance already moved
Therefore,
y = 400 - 50x
Answer:
Step-by-step explanation:
y= -50x + 400
