Answer:
m<A = 98.25
m<B = 81.75
m<C = 113
m<D = 113
m<E = 67
Step-by-step explanation:
3x + 12 + 5x - 18 = 180
8x - 6 = 180
8x = 186
x = 23.25
3x + 12
3(23.25) + 12
81.75
5x - 18
5(23.25) - 18

16y = 192
y = 12

What is the radius of
this cylinder if the
volume is 75.4 in^3 and
the height is 6 inches
Answer:
Radius of cylinder = 2 inch (Approx.)
Step-by-step explanation:
Given:
Volume of cylinder = 75.4 in³
Height of cylinder = 6 inches
Find;
Radius of cylinder
Computation:
Volume of cylinder = πr²h
Volume of cylinder = (3.14)r²(6)
75.4 = (18.84)r²
(Radius of cylinder )² = 75.4 / 18.84
(Radius of cylinder )² = 4.002123
(Radius of cylinder) = 2
Radius of cylinder = 2 inch (Approx.)

5(9-x)/3 +1 less than 11
find x
Answer:
x > [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
[tex]\frac{5(9-x)}{3+1}<11[/tex]
Add 3 and 1 to get 4.
[tex]\frac{5(9-x)}{4}<11[/tex]
Use the distributive property to multiply 5 by 9−x.
[tex]\frac{45-5x}{4}<11[/tex]
Subtract 45/5 from both sides.
[tex]-\frac{5}{4}x<11-\frac{45}{4}[/tex]
Since 44/4 and 45/4 have the same denominator, subtract them by subtracting their numerators.
[tex]-\frac{5}{4} x<-\frac{1}{4}[/tex]
Multiply both sides by -4/5, the reciprocal of -5/4. Since -5/4 is negative, the inequality direction is changed.
[tex]x>-\frac{1}{4} (-\frac{4}{5} )[/tex]
Multiply -1/4 times -4/5 by multiplying numerator times numerator and denominator times denominator.
[tex]x>\frac{-(-4)}{4 x 5}[/tex]
[tex]x>\frac{1}{5}[/tex]
A company's revenue from selling x units of an item is given as R=1700x-2x^2 . If sales are increasing at the rate of 25 units per day, how rapidly is revenue increasing ( in dollars per day ) when 250 units have been sold
Answer:
The daily rate is: 17500 units per day
Step-by-step explanation:
Given
[tex]R = 1700x - 2x^2[/tex]
[tex]\frac{dx}{dt} = 25[/tex]
Required
Find [tex]\frac{dR}{dt}[/tex] when [tex]x = 250[/tex]
We have:
[tex]R = 1700x - 2x^2[/tex]
Differentiate both sides with respect to time
[tex]\frac{dR}{dt} = 1700\frac{dx}{dt} - 4x\frac{dx}{dt}[/tex]
Factorize
[tex]\frac{dR}{dt} = (1700- 4x)\frac{dx}{dt}[/tex]
Substitute: [tex]\frac{dx}{dt} = 25[/tex] and [tex]x = 250[/tex]
[tex]\frac{dR}{dt} = (1700- 4x)\frac{dx}{dt}[/tex]
[tex]\frac{dR}{dt} = (1700- 4*250)*25[/tex]
[tex]\frac{dR}{dt} = (1700- 1000)*25[/tex]
[tex]\frac{dR}{dt} = 700*25[/tex]
[tex]\frac{dR}{dt} = 17500[/tex]

The perimeter of a rectangular hall is 120m. If its breadth is 25m, find the length
Answer:
[tex] 35m [/tex]
Step-by-step explanation:
Given :-
The perimeter of a rectangular hall is 120m.Its breadth is 25m .And we need to find the length of the rectangle . We can use the formula to find the perimeter of rectangle , as ,
Perimeter of rectangle :-
[tex]\implies Perimeter = 2( l + b)[/tex]
Let the length of the rectangle be x . Plug in the respective values ,[tex]\implies 120m = 2 ( x + 25m) \\\\\implies x + 25m =\dfrac{120m}{2}\\\\\implies x + 25m = 60m \\\\\implies x = 60m - 25m \\\\\implies x = 35m [/tex]
Hence the length of the rectangle is 35 m .

Answer:
y=x+3
Step-by-step explanation:
when you connect all the dots it makes a straight linear line. then you can use the format y=mx+b
y is the y value
m is the slope (change in y divided by change in x or, rise over run)
x is the x value
b is the y intercept (the y value where the line will touch the y axis/vertical line)
to make the equation
y=mx+b
y and x are variables so you dont need to write them
the slope is rise/run just pick two points such as the first point (0,3) and the second point (1,4)
between these points it changes one unit to the right (1) and one unit up vertically meaning 1/1
=1
when the slope is 1 you get
y=1x+b which is just y=x+b
then the y intercept
the first dot is touching the y axis line and it's y value is 3
y=x+3
hope this helps

An object is thrown straight up from the top of a building 150 feet tall with an initial velocity of 12 feet per second. The height of the object as a function of time can be modeled by the function y = –16x2 +12x + 150, where y is the height of the object (in feet) and x is the time in seconds after it is thrown.
Answer:
will this work or help ?
Step-by-step explanation:
The given equation governs the height versus time of the object. h(0) = 64, so the ground is considered at h = 0. The question is at what time is h = 0? So, set h = 0 and solve for t.
-16t^2 + 48t + 64 = 0
We can divide both sides of this equation by -16 for simpler numbers. We get
t^2 - 3t - 4 = 0
We can factor this equation:
(t - 4)(t + 1) = 0
So, t = 4 and t = -1 are solutions.
But, time must be positive, so t = -1 makes no sense, so we discard it. This leaves
t = 4 sec.
A 20-ounce soda bottle is supposed to contain 20 ounces of soda. The distribution of the actual amount of soda in a 20-ounce soda bottle is approximately normal. A curious student randomly selects fifteen 20-ounce soda bottles from various retailers and carefully measures their content to see if the soda company is cheating the customers. The mean and standard deviation of the fifteen bottles is 19.4 ounces and 0.25 ounces, respectively. Which of the following is the test statistic for the appropriate test to determine if the average amount of soda that is contained in their 20-ounce soda bottles is significantly less than 20-ounces?ghtly news dropping? In a survey taken in 2013, 24 out of 40 adults surveyed responded that they had watched the local TV news at least once in the last month. In a similar survey in 2010, 40 out of 50 adults said they had watched the local TV news at least once in the last month. Is this convincing evidence that the proportion of adults watching the local TV news dropped between 2010 and 2013? For a significance test with the hypotheses where p1 is the proportion of all adults who watched the local news at least once a month in 2013, and p2 is the proportion for 2010, which of the following is closest to the standard error for the test statistic?
Answer:
A
Step-by-step explanation:
The appropriate inference procedure in this case is a one-sample t test for a mean. The test statistic for this test is [tex]t=\frac{19.4-20}{\frac{0.25}{\sqrt{n} } }[/tex].
The test statistic for this test is ;
t = 19.4 - 20/ 0.25/√n
What does "normal" describes in statistics?Normal usually refers to the word "normal" in normal distribution.
The word normal is used when something occurs that have occured frequently. The normal distribution is somewhat similar where the main observation (mean or its surrounding) occurs frequently and as we go far from mean, its chances decrease.
We are given that 20-ounce soda bottle is supposed to contain 20 ounces of soda. The distribution of the actual amount of soda in a 20-ounce soda bottle is normal.
The appropriate procedure in this case is a one-sample t test for a mean.
The test statistic for this test is ;
t = 19.4 - 20/ 0.25/√n

The complete table is shown in attached figure.
The graph of y = 2x + 3 is shown in attached figure.
What is linear expression?
A linear expression is an algebraic statement where each term is either constant or variable raised to the first power.
Given that;
The equation is y = 2x + 3
Now, For Complete the table we can calculate as;
For first column;
The value of x = -2
Hence, The value of y is calculated as;
y = 2x + 3
y = 2 × -2 + 3
y = -4 + 3
y = -1
Thus, For first column of table;
x = -2 and y = -1
And, For third column;
The value of x = 0
Hence, The value of y is calculated as;
y = 2x + 3
y = 2 × 0 + 3
y = 0 + 3
y = 3
Thus, For third column of table;
x = 0 and y = 3
And, For fourth column;
The value of x = 1
Hence, The value of y is calculated as;
y = 2x + 3
y = 2 × 1 + 3
y = 2 + 3
y = 5
Thus, For fourth column of table;
x = 1 and y = 5
And, For sixth column;
The value of x = 3
Hence, The value of y is calculated as;
y = 2x + 3
y = 2 × 3 + 3
y = 6 + 3
y = 9
Thus, For sixth column of table;
x = 3 and y = 9
Thus, The complete table is shown in attached figure.
The graph of y = 2x + 3 is shown in attached figure.
