Answer:
Stanley needs 31 feet and 2 inches of fencing.
Step-by-step explanation:
In order to answer this problem, you need to find the perimeter of the dog run.
Since: [tex]P=2(l+w)[/tex]
and [tex]l=149[/tex] inches & [tex]w=56[/tex] inches
Plug in what we know :
[tex]P=2(149+56)[/tex]
and solve:
[tex]P=410[/tex] inches
The dog run has a perimeter of 410 inches.
However, now we need to subtract 36 inches since the gate doesn't need fencing.
[tex]410-36=374[/tex] inches.
The dog run needs 374 inches of fencing.
In order to find out how many feet of fencing that is, divide it by 12.
[tex]\frac{374}{12}[/tex] = 31.16666667 OR [tex]31\frac{2}{12}[/tex], meaning 31 feet and 2 inches.
Answer:
31 feet and 2 inches of fencing :))<3

Michelle read 72 pages in 3 hours. What was her unit rate of pages read per hour?
Answer:
24 pages per hour
Step-by-step explanation:
72 pages = 3 hours
To find the rate of pages per hour, divide both sides by 3.
72/3 = 24, 3/3=1
24 pages per 1 hour, 24:1

Answer:

Step-by-step explanation:
Answer:
C
Step-by-step explanation:
First of all we can simplify the the first therm because a property of power says that we can simplify a power of power by multiply the exponents
a^4b^8c^2
For the same property 2c^5 becomes 8c^15
now we have
(a^4b^8c^2)(6a^3b)(8c^15)/4a^6b^12c^3
if we simplify the numbers we can obtain
(a^4b^8c^2)(6a^3b)(2c^15)/a^6b^12c^3
If we simplify the parameters we can obtain
12ac^14/b^3

This graph is from a publication of the Centers for Disease Control and Prevention (2017). The y-axis shows the percentage living with diabetes.
The Board of Directors of a medical school wants to use the trend to predict the percentage in 2020 so that they can help train enough doctors to handle the growing numbers. Use a visual estimate of the line of best fit to make a prediction. Do you think your estimated line of best fit will be accurate? Explain why or why not.
Answer:
My estimate is around 16 million cases by 2020
Step-by-step explanation:
I used the formula of rise over run
(The "Rise over Run" formula is y2-y1/x2-x1)
I used 2010's total of cases 22 million and 1960's 4 million
Now I subtract 2010 and 1960
Which is 40 or 4 in this case
Then I subtracted 22 million by 4 million which is 5.5
Round 5.5 to 6 (Since it is an estimate)
Divide 6 and 4
6/4= 1.5 which I rounded to 2 million now I start at 1960's 4 million case and add 2 million for 10 year or multiply 6 by 2 which is 12 and add it by 4 which is 16
Hence 16 million

Josh drops his phone from a height of 50 feet. The situation is best modeled by h = -16t^2 +50, where h is the height in feet and t is the time in seconds. How long will it take for the phone to hit the ground? Round to the nearest tenth.
It will take approximately 1.8 seconds for the phone to hit the ground.
What is meant by an Equation?A mathematical statement which includes two sides, namely, left and right hand side consisting of numbers or variables, which are connected by an "equal to" sign is called an equation.
Given in the question that,
Equation representing the situation of the height of the phone in t seconds, is,
h = -16t² + 50
where h is the height in feet and t is the time in seconds.
The phone hits the ground means that the height is 0 there.
Substituting h = 0,
-16t² + 50 = 0
-16t² = -50
t² = 50 / 16
t² = 3.125
t = 1.767 ≈ 1.8 seconds
Hence the time taken is 1.8 seconds to the nearest tenth.

what is angle ?A geometric shape known as an angle is created when two rays or line segments come together to form its vertex. The two rays or line segments are known as the angle's sides. Angles are used to describe the orientation, direction, and position of lines and forms in geometry. They are commonly measured in degrees or radians. The magnitude of an angle can range from 0 degrees (representing no rotation) to 360 degrees depending on how much the two sides or rays are rotating (corresponding to a full rotation).
given
We may utilise the Law of Cosines to determine the potential values of U:
A2 + B2 - 2ab cos = c2 (C)
where a and b are the lengths of the other two sides, and c is the length of the side that faces angle C. We'll write c for the length of side SU and a for the length of side ST.
Based on the facts provided, we can:
a=630 inches
b = u (unknown) (unknown)
C = ∠T = 7°
We can apply the Law of Sines to determine the length of b:
B = a / sin = b / sin(B) (A)
where A denotes the angle that faces side a, and B denotes the angle that faces side b. To solve for b, we obtain: b = a / sin(B) (A) .

If 5x + y = 20 and 10x - 2y = 50 are two linear equations in two variables. Find the value of x and y.
x = 1, y = 1
x = 2, y = 1/2
x = 9/2, y = -5/2
x = 1, y = 5/2
Answer:
x = 9/2, y = -5/2
Step-by-step explanation:
5x + y = 20
10x - 2y = 50
There's multiple ways to do this, but I will solve using substitution.
Isolate variable y on the first equation.
5x + y = 20
y = 20 - 5x
Substitute the value of y for 20 - 5x in the second equation.
10x - 2(20 - 5x) = 50
Use distributive property:
10x - 40 + 10x = 50
Combine like terms:
20x - 40 = 50
20x = 90
x = 90/20
x = 9/2
Substitute x for 9/2 and solve for y:
y = 20 - 5(9/2)
y = 20 - 45/2
y = 40/2 - 45/2
y = -5/2
Answer:
x =9/2, y = -5/2
Step-by-step explanation:
5(9/2) + -(5/2)= 20
45/2 + -5/2 = 20
40/2 = 20
10(9/2) - 2(-5/2) = 50
90/2 + 10/2 = 50
45 + 5 = 50

You roll a 6-sided die.
What is P(5)?
Answer:
1/6
Step-by-step explanation:
you have a 6 sided die that is numbered 1, 2, 3, 4, 5, and 6.
you roll it once, so the probability that you will roll a five is 1/6
this is because you only want one specific number so that goes on the numerator of the fraction.
then, you have to multiply how many sides you have on the die to the number of rolls. in this case we have one roll and six sides. so the six goes on the denomerator side of the fraction

Answer:

Step-by-step explanation:
Breakeven quantity are the number of units produced and sold at which net income is zero
Breakeven quantity = fixed cost / price – variable cost per unit
Fixed costs are costs that do not vary with output. e,g, rent, mortgage payments
If production is zero or if production is a million, Mortgage payments do not change - it remains the same no matter the level of output.
Hourly wage costs and payments for production inputs are variable costs
Variable costs are costs that vary with production
fixed cost = $2450
Variable cost = $75
price = $145
(2450) / (145 - 75) = 35
