The length of a rectangle flower bed is 5ft longer than its width. A sidewalk with a width of 3ft surrounds the bed. If the total area of the bed and sidewalk is 546ft^2, what are the dimensions of the flower bed ?
Answer:
[tex]W=15ft[/tex]
[tex]L=20ft[/tex]
Step-by-step explanation:
From the question we are told that:
Length of Bed [tex]L=5+W[/tex]
Width of sidewalk [tex]W_s=3ft[/tex]
Area of the bed and sidewalk [tex]A_t= 546ft^2[/tex]
Generally the equation for Area of the bed and sidewalk[tex]A_t[/tex] is mathematically given by
[tex]Area=L*B[/tex]
[tex]A_t=((3+3)+L)*((3+3)+W)[/tex]
Therefore
[tex]546=((3+3)+(5+W))*((3+3)+W)[/tex]
[tex]0=((6+(5+W))*((6)+W)-546[/tex]
[tex](11+W)*(6+W)-546=0[/tex]
[tex]W^2+17B-480=0[/tex]
Solving the Quadratic Equation
[tex]W=15ft[/tex] (Using only positive root)
Generally the Length L is mathematically given by
[tex]L=5+15[/tex]
[tex]L=20ft[/tex]
HOW TO DO THIS QUESTION PLEASE
Answer:
34
Step-by-step explanation:
[tex]\frac{2}{5}*85[/tex]
Long way
multiply the two numeratorsmultiply the two denominatorssimplify the new fractions[tex]\frac{85}{1}*\frac{2}{5} \\ \\ \frac{170}{5} \\ \\ =34[/tex]
short way
-can be simplified before mulitplying
factor out common factors in the numerator and denominator[tex]\frac{85}{1} *\frac{2}{5} \\ \\ \frac{17}{1}*\frac{2}{1} =34[/tex]
Think 85 and 5 as nickels. You need 20 nickels to make 100. Subtract 100 by 85 to get 15. You get 3 nickels and 17 nickels. 17 is the common factor. Multiply 17 by 2 to get your answer.

Answer:
x=34
Step-by-step explanation:
Again we are given an angle's ( x to be more specific ) opposite side length and the adjacent side length so we will use trig ratio tangent
Recall that tan = opposite over hypotenuse
[tex]tan(x)=\frac{29}{43}[/tex]
* multiply each side by the inverse of tan ( [tex](tan)^-^1[/tex] )
[tex]tan(x)*tan^-^1=x\\tan^-1*\frac{29}{43} =33.99645915\\x=33.99645915[/tex]
Finally we round to the nearest tenth of a degree and get that x = 34
what's equivalent to (9 7/8 + 2 4/5) - 1/2
Answer:
12.175
Step-by-step explanation:
also
Step-by-step explanation:
C) 9 7/8 - (- 2 4/5) - (- 1/2) =
= 9 7/8 + 2 4/5 + 1/2 (F)
D) - (- 9 7/8 + 2 4/5) - 1/2) =
= 9 7/8 - 2 4/5 - 1/2 (F)
E) 9 7/8 - (- 2 4/5 - 1/2) =
= - 7/8 + 2 4/5 + 1/2 (F)
Answer:
12 7/40
Step-by-step explanation:
9 7/8 = 9 35/40
2 4/5 = 2 32/40
add: 11 67/40
67/40 = 1 27/40
11 + 1 27/40 = 12 27/40
12 27/40 - 20/40 = 12 7/40

Elisa ran a total of 8 4/5 miles on Saturday and Sunday. If she ran 5 1/4 miles on Saturday, how many miles did she run on Sunday?
Answer: [tex]3\dfrac{11}{20}\ \text{miles}[/tex]
Step-by-step explanation:
Given
Elisa run a total of [tex]8\frac{4}{5}[/tex] miles on Saturday and Sunday.
If she runs [tex]5\frac{1}{4}[/tex] miles on Saturday
Then, distance traveled on Sunday is given by
[tex]\Rightarrow 8\dfrac{4}{5}-5\dfrac{1}{4}\\\\\Rightarrow \dfrac{44}{5}-\dfrac{21}{4}\\\\\Rightarrow \dfrac{44\times 4}{5\times 4}-\dfrac{21\times 5}{4\times 5}\\\\\Rightarrow \dfrac{71}{20}\\\\\Rightarrow 3\dfrac{11}{20}\ \text{miles}[/tex]

The graph shows two lines, A and B.
A graph is shown with x- and y-axes labeled from 0 to 6 at increments of 1. A straight line labeled A joins the ordered pair 2, 6 with the ordered pair 6, 2. Another straight line labeled B joins the ordered pair 0, 3 with the ordered pair 4.5, 6.
Part A: How many solutions does the pair of equations for lines A and B have? Explain your answer.
Part B: What is the solution to the equations of lines A and B? Explain your answer.
Answer:
(3, 5)Step-by-step explanation:

The volume of a cylinder is 121 cubic inches and its height is 4 inches.
a)
What is the radius of the cylinder?
b) What is the surface area of the cylinder? Give your answer in terms of īt.
Answer:
r=3.10in
SA= 138.22 in square
Step-by-step explanation:
Given data
Volume = 121 in^3
Height= 4 in
a) What is the radius of the cylinder?
We know that volume
V=πr^2h
121= 3.14*r^2*4
121= 12.56r^2
121/12.56= r^2
9.63=r^2
r= √9.63
r=3.10in
b) What is the surface area of the cylinder? Give your answer in terms of īt.
The surface area of cylinder is expressed as
SA=2πrh+2πr^2
SA= 2*3.14*3.1*4+ 2*3.14*3.1^2
SA= 77.872+60.3508
SA= 138.22 in square

Expand and simplify (x – 2)(2x + 3)(x + 1)
Answer:
Step-by-step explanation:
(x-2)(2x+3)(x+1)
=x(2x+3)-2(2x+3)(x+1)
=(2x^2+3x-4x-6)(x-1)
=(2x^2-x-6)(x-1)
=2x^2(x-1)-x(x-1)-6(x-1)
=2x^3-2x^2-x^2+x-6x+6
=2x^3-3x^2-5x+6
( x - 2 )( x + 1 )( 2x + 3 ) =
( x^2 - x - 2 )( 2x + 3 ) =
2x^3 - 2x^2 - 4x + 3x^2 - 3x - 6 =
2x^3 + ( -2 + 3 )x^2 + ( - 4 - 3 )x - 6 =
2x^3 + x^2 - 7x - 6

the flat fee doesnt chamge no matter how much he uses his data
the charge for every gigabyte does change
Ex: if he uses 3 gigabytes of data in one month, that's
5 + 5 + 5 = $5 x 3 = $15
So taking this into consideration youd write the following
$41.50 + $5x = $52.50 (since this is what we want to equal)
then solve for x

iq scores are normally distributed with a mean of 100 and a standard deviation of 15. What percentage of people have an IQ between 130 and 100 a)13.5% b)47.5% c)95% d)27%
Answer:
"approximately 47.%"
Step-by-step explanation:
Using the statistical function normalcdf( on my old TI-38 calculator:
normalcdf(100,130, 100, 15) returns the fraction 0.477,
so the final answer here is "approximately 47.%"
A small town has two local high schools. High School A currently has 750 students and is projected to grow by 45 students each year. High School B currently has 850 students and is projected to grow by 25 students each year. Let A represent the number of students in High School A int years, and let B represent the number of students in High School B after t years. Write an equation for each situation, in terms of t, and determine after how many years, t, the number of students in both high schools would be the same.
Answer: A=750 +75*t
B=900 +25*t
There would be 975 students in each high school in year 3 when they are expected to have the same number of students.
Step-by-step explanation:
A = B
750 +75*t=900 + 25*t
Solving:
75*t -25*t= 900 - 750
50*t= 150
t=3
This indicates that in year 3 both High Schools are projected to have the same number of students. To get that amount, you simply replace this value in the expressions:
A=750 +75*t= 750 +75*3= 975
B=900 + 25*t=900 + 25*3= 975
There would be 975 students in each high school in year 3 when they are expected to have the same number of students.

Enter an algebraic expression to model the given context. Give your answer in simplest form.
The principal amount P originally deposited in a bank account plus 0.8% interest
The algebraic expression is
Answer:
A=P(1.008t)
Step-by-step explanation:
Given data
Principal=P
Rate= 0.8%
The expression for the amount in a simple interest is given as
A=P(1+rt)
Hence the expression is
A=P(1+0.008t)
simplify
A=P(1.008t)
