Answer: 50 Words
Step-by-step explanation: We know Kyle can write a 300-word essay in an hour or 1 hour. We want to know how many words Kyle would have in his essay if he wrote one in 10 minutes.
First, find how many words Kyle can write per minute. Simply do this by dividing 300 by 60, since there are 60 minutes in a hour.
300/60 = 5. So, Kyle can write 5 words per minute.
Now, simply multiply 5 by 10 to find how many words Kyle would write in 10 minutes.
5 x 10 = 50. So, Kyle can write 50 words in his essay if he writes for 10 minutes.
in a community center 15 bottles are evenly spaced 12 cm apart from each other in a row for a competition
what is the distance from the fourth bottle to the tenth bottle?
Answer:
72 cm
Step-by-step explanation:
Relative to the first bottle, there are n - 1 spaces between the first bottle and the nth bottle. Since, each bottle is placed relative to the first bottle.
Now, for the fourth bottle, that is, n = 4, there are 4 - 1 = 3 spaces between the first and fourth bottle.
Since each space is 12 cm, the distance between the first and fourth bottle is 12 cm × 3 = 36 cm.
Now, for the tenth bottle, that is, n = 10, there are 10 - 1 = 9 spaces between the first and fourth bottle.
Since each space is 12 cm, the distance between the first and fourth bottle is 12 cm × 9 = 108 cm.
So, the distance between the fourth bottle and tenth bottle is distance between tenth bottle to first bottle minus distance between fourth bottle to first bottle = 108 cm - 36 cm = 72 cm

Which expression represents the volume of the pyramid? StartFraction x cubed + 2 x squared Over 3 EndFraction cm3 StartFraction x squared + 2 x squared Over 2 EndFraction cm3 StartFraction x cubed Over 3 EndFraction cm3 StartFraction x cubed + 2 x squared Over 2 EndFraction cm3
Answer:
(x³+2x²)/3 cm³Step-by-step explanation:
Find the diagram attached
Volume of a pyramid = 1/3 * Base area * height
Base area = x*x
Base area = x²
Height = x+ 2
Get the volume:
Volume of the pyramid = 1/3 * x² * x+2
Volume of the pyramid = x²(x+2)/3
Volume of the pyramid = (x³+2x²)/3 cm³
Answer:
D aka (x³+2x²)/3 cm³

i’ll make u brainliest if u answer
Answer:
The solution set is (5,6).
Step-by-step explanation:
Given equations are:
-6x + 6y= 6 Eqn 1
-6x + 3y=-12 Eqn 2
Subtracting Eqn 2 from Eqn 1
(-6x+6y)-(-6x+3y)= 6-(-12)
-6x+6y+6x-3y=6+12
3y = 18
Dividing both sides by 3
[tex]\frac{3y}{3}=\frac{18}{3}\\y=6[/tex]
Putting y=6 in Eqn 1
-6x+6(6)=6
-6x+36=6
-6x=6-36
-6x=-30
[tex]\frac{-6x}{-6}=\frac{-30}{-6}\\x=5[/tex]
Hence,
The solution set is (5,6).

in one year dog's weigh from 64 pounds to 80 pounds . by what percentage did the dog's weght increase
Answer:
15%
Step-by-step explanation:
First, let's find how many pounds the dog's weight increased by during the year.
80 - 64 = 16
Now, knowing that the dog's weight increased by 16 pounds, we can use that to figure out the percentage of 16 out of 64 (divide them, then multiply by 100 to get a percentage).
[tex]\frac{16}{64}[/tex] • 100 = 0.25 • 100 = 25%
3. Problem 2: Suppose a radio manufacturer has the total cost function C (x) = 43x + $ 1850 and the revenue function R (x) = $ 80x. Where "x" is the number of radios manufactured and sold. Find:
plissssssssssssss helpppp
Given that,
Total cost function, C (x) = 43x + $1850
The revenue function R (x) = $80x
To find,
The number of units that must be produced and sold to break even.
Solution,
At break even, cost = revenue
43x + $1850 = $80x
Subtract 80x from both sides.
43x + 1850 -80x = $80x -80x
1850 = 80x-43x
37x = 1850
x = 50
So, the required number of units are 50.
Write an equation for the statement. Then, solve the equation:
The volume of a can varies jointly as the height of the can and the square of its radius. A can with an 8 inch
height and 4 inch radius has a volume of 402.12 inches cubed. What is the volume of a can that has a 2 inch
radius and a 10 inch height?
PLZZ help
Answer:
V = 125.6 in³
Step-by-step explanation:
let V be volume, h the height and r the radius, then the equation relating the quantities is
V = khr² ← k is the constant of variation
To find k use the condition V = 402.12, h = 8, r = 4
402.12 = k × 8 × 4² = 128k ( divide both sides by 128 )
3.14 = k [ note 3.14 is π )
V = 3.14hr² ← equation of variation [ V = πr²h ]
Given r = 2 and h = 10, then
V = 3.14 × 10 × 2² = 3.14 × 40 = 125.6

A store owner buys cell phones for $40 and marks up the price by 25%. What is the sale price of a phone?
Answer:
$50
Step-by-step explanation:
Price of the cell phone bought p = $40
% of markup in price = 25%
Selling price of the cell phone = p + (%)p
Selling price of the cell phone = P + (0.25)p
Selling price of the cell phone = p + 0.25p
Selling price of the cell phone = 1.25p
Selling price of the cell phone = 1.25 * $40
Selling price of the cell phone = $50
I = $60, P = $750, r = 4%, t = ?. Find the amount of time
Answer:
The time required to accumulate simple interest of $ 60.00
from a principal of $ 750.00 at an interest rate of 4% per year is 2 years.
Step-by-step explanation:
Given
Interest I = $60Principle P = $750Interest rate r = 4% = 0.04To determine
Time period t = ?
Using the formula
I = Prt
t = I / Pr
substitute I = $60, P = $750 and r = 0.04 in the equation
t = 60 / ( 750 × 0.04 )
t = 2 years
Therefore, the time required to accumulate simple interest of $ 60.00
from a principal of $ 750.00 at an interest rate of 4% per year is 2 years.

Answer: 1.72.......
Step-by-step explanation: 4.3x + 7 + 5x = 16 + 7
=> 7 + (5x + 4.3x) = 16 + 7
7 + 9.3x = 23
9.3x = 23 - 7 [ 7 becomes -7 when transferred to RHS]
9.3x = 16
x = 16 /9.3 [ 9.3 becomes 1/9.3 when transferred to RHS]
x = 1.72......

At 10 AM horn and Tyler both started running toward each other from opposite ends of a 10 mile path along the river. On runs out a piece of 12 minutes per mile. Tyler is it a piece of 15 minutes from now. How far is home run after half an hour
Complete question :
At 10:00 am, Han and Tyler both started running toward each other from opposite ends of a 10 mile path along a river. Han runs at a pace of 12 minutes per mile Tyler runs at a pace of 15 minutes per mile how far does Han run after a half hour
Answer:
2.5 miles
Step-by-step explanation:
Given :
Distance between Horn and Tyler = 10 miles
Horn's pace = 12 minutes per mile
Tyler's pace = 15 minutes per mile
Horn's distance after half an hour :
Time = Half an hour = 30 minutes
Horn's speed = distance / time
Horn's speed = 1 mile / 12 minutes = 0.83333 miles per minute
Hence, Horn's distance after half an hour :
Distance = speed * time
Distance = 0.83333 miles per minute * 30 minutes
Distance = 2.5 miles
You run the same speed every day. Saturday you ran 4 miles in 32 minutes. On Sunday you ran 3 miles in m minutes.
36 minutes
12 minutes
28 minutes
24 minutes
Step-by-step explanation:
4 miles =32
3 miles=m
32×3=4m
96=4m
m=96/4
=24
Solving Quadratic Equations using the Square Root Property
[tex]x^2+7x+10=0[/tex]
but the teacher's guide says the answer is 17i
Answer:
[tex] x = -2 [/tex] or [tex] x = -5 [/tex]
Step-by-step explanation:
You need to complete the square before you can take the square root of both sides.
[tex] x^2 + 7x + 10 = 0 [/tex]
Subtract 10 from both sides.
[tex] x^2 + 7x = -10 [/tex]
To complete the square, you need to add the square of half of the x-term coefficient to both sides.
The x-term coefficient is 7. Half of that is 7/2. Square it to get 49/4. Now we add 49/4 to both sides of the equation.
[tex] x^2 + 7x + \dfrac{49}{4} = -10 + \dfrac{49}{4} [/tex]
[tex] (x + \dfrac{7}{2})^2 = -\dfrac{40}{4} + \dfrac{49}{4} [/tex]
[tex] (x + \dfrac{7}{2})^2 = \dfrac{9}{4} [/tex]
Now we use the square root property, if
[tex] x^2 = k [/tex], then
[tex] x = \pm \sqrt{k} [/tex]
[tex] x + \dfrac{7}{2} = \pm \sqrt{\dfrac{9}{4}} [/tex]
[tex] x + \dfrac{7}{2} = \pm \dfrac{3}{2} [/tex]
[tex] x + \dfrac{7}{2} = \dfrac{3}{2} [/tex] or [tex] x + \dfrac{7}{2} = -\dfrac{3}{2} [/tex]
[tex] x = -\dfrac{4}{2} [/tex] or [tex] x = -\dfrac{10}{2} [/tex]
[tex] x = -2 [/tex] or [tex] x = -5 [/tex]
