Answer:
width = 5 feet
length = 13 feet
Step-by-step explanation:
length of a rectangular vegetable bed is 3 feet more than twice the width
l = 2x + 3
length of the fence around the bed is 36 feet
p = 2(l + x)
36 = 2(l + x)
18 = l + x
Substitute for l
18 = (2x + 3) + x
18 = 3x + 3
15 = 3x
x = 5
l = 2(5) + 3 = 13
Answer:
width= 5
length=13

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
98.25
6y - 5 + 10y - 7 = 180
16y - 12 = 180

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 "freshman 15" is the name of a common belief that college students, particularly women, gain an average of 15 pounds during their first year of college. In one study of 110 female first‐year college students (Psychology of Women Quarterly, vol 17, pp.119‐126, 1993), the mean weight was 130.6 pounds at the beginning of the study and 131.4 pounds six months later. The standard deviation was about 20 pounds at each time.
Required:
a. Estimate the change in the mean weight over this six‐month period.
b. Is this sufficient information to find a confidence interval or conduct at estimate about the change in the mean over six months? If not what else do you need to know?
Answer:
A) - 0.8 Ibs
B) There isn't enough information
The standard deviations of the difference scores is needed
Step-by-step explanation:
N = 110 female first year college students
Mean weight at beginning of study = 130.6 Ib
Mean weight after six ( 6 ) months = 131.4 Ib
standard deviation = 20 pounds
A) Determine the change in the mean weight over the six(6) months period
mean weight at beginning - mean weight after six(6) months
= 130.6 - 131.4
= -0.8 Ibs
B) Determine if there is sufficient information to find a confidence interval
There isn't sufficient information to determine the confidence interval but in other to determine the confidence interval or conduct an estimate You need standard deviations of the difference scores to calculate the standard error of mean

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 .
Determine the area of this triangle...
Answer:
650,000 cm²
Step-by-step explanation:
10x6.5=65 METERS squared. They want it in CENTIMETERS squared.
65m² = 650,000cm²
Answer:
32.5[tex]m^{2}[/tex]
Step-by-step explanation:
The coloured triangle with the blank triangle area =
(14m x 6.5m)÷2 = 45.5[tex]m^{2}[/tex]
The blank triangle area =
[(14-10m) x 6.5m]÷2 = 13[tex]m^{2}[/tex]
Therefore:
The coloured triangle area =
(45.5 - 13)[tex]m^{2}[/tex]
=32.5[tex]m^{2}[/tex]
Find the side lengths of the triangle in this picture.
Answer:
Hypotenuse: 41 meters, Long leg: 40 meters, Short leg: 9 meters.
Step-by-step explanation:
According to the statement, we have the following information about the lengths of the right triangle:
Hypotenuse
[tex]3\cdot x + 14[/tex]
Long leg
[tex]3\cdot x + 13[/tex]
Short leg
[tex]x[/tex]
By the Pythagoric Theorem, we have the following expression:
[tex](3\cdot x + 14)^{2} = x^{2} + (3\cdot x + 13)^{2}[/tex] (1)
[tex]9\cdot x^{2}+84\cdot x + 196 = x^{2} + 9\cdot x^{2} + 78\cdot x + 169[/tex]
[tex]9\cdot x^{2} + 84\cdot x + 196 = 10\cdot x^{2} + 78\cdot x +169[/tex]
[tex]x^{2} -6\cdot x -27 = 0[/tex]
[tex](x-9)\cdot (x+3) = 0[/tex]
As length is a positive variable by nature, then the only possible solution is [tex]x = 9[/tex]. Lastly, the side lengths of the right triangle are:
Hypotenuse: 41 meters, Long leg: 40 meters, Short leg: 9 meters.
Find the length of the third side of each triangle - Find Hypotenuse

Which one of the following is an ordered pair?
{-3, 5}
(2, 4, 0)
(0, 6)
1, 3
9514 1404 393
Answer:
(c) (0, 6)
Step-by-step explanation:
Conventionally, an "ordered pair" is a pair of items in parentheses, separated by a comma. The items don't have to be numbers. (0, 6) is an ordered pair.
__
Comments on the other answer choices
Curly braces are usually used as delimiters of a set, not an ordered pair.
Three items do not constitute a "pair." Rather, they are a "triple."
Items without any particular indicator of grouping are usually not considered a "pair."
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]
Natalie paid $20.7 for 3 small pizzas and a salad which was $3.
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.
Find the length of a to the nearest tenth using the Pythagorean theorem
Answer:
Ab^2 = CA^2 + BC^2
8^2 = 6^2 + a^2
64 = 36 + a^2
64-36 = a^2
28 = a^2
square root of 28 = square root of a^2
5 ,29 = a

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.
