Answer:
1/5+1/2²+3/10•5=1/7²+15/100
The resultant of the expression (1/5+1/2)^2+3/10⋅5 in mixed number will be 1 99/100.
What is a number system?The number system is a way to represent or express numbers.
Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.
As per the given expression,
(1/5+1/2)^2+3/10⋅5
⇒ (1/5+1/2)²+ 15/10
Take LCM in the bracket as 10
⇒ [(2 + 5)/10]² + 15/10
⇒ (7/10)² + 15/10
⇒ 49/100 + 15/10
Take LCM as 100
⇒ (49 + 150)/100 = 199/100
⇒ 1 99/100
Hence "The resultant of the expression (1/5+1/2)^2+3/10⋅5 in mixed number will be 1 99/100".

Answer:
Area: [tex]5x[/tex], Perimeter: [tex]2x+10[/tex]
Step-by-step explanation:
a)
We know that for any rectangle the area is [tex]l*w[/tex], where [tex]l[/tex] is the length and [tex]w[/tex] is the width.
Because the width is [tex]x[/tex] and the length is [tex]5[/tex], the area is [tex]x*5[/tex] or [tex]5x[/tex].
b)
We know that for any rectangle the perimeter is [tex]2(l+w)=l+w+l+w[/tex], where [tex]l[/tex] is the length and [tex]w[/tex] is the width.
Because the width is [tex]x[/tex] and the length is [tex]5[/tex], the perimeter is [tex]2(x+5)=2x+10[/tex].
So, the answers are [tex]Area:5x,~Perimeter:2x+10[/tex]

Step-by-step explanation:
Flowers - Samantha and Maria purchased flowers. Samantha bought five roses for "r" dollars each and four daises for "d" dollars each. Altogether, Samantha spent $32 on flowers. Maria purchased one rose for "r" dollars apiece and six daisies for "d" dollars apiece - spending $22 total.
a) Write a system of equations (two linear equations) using appropriate variables.
b) Solve the system to find the cost of roses and daisies. Use any strategy that you've learned.
Answer:
part a[tex]5r + 4d = 32[/tex]
[tex]r + 6d = 22[/tex]
part bthe value of roses is 4 dollars a pieces and that of daisies is 3 bucks a piece
Step-by-step explanation:
part afor part a just denote r for roses and rerecord the question in terms of a function of roses and daisies the right hand side should be the prices or cost
part bsolve the two equations simultaneously or by substitution.
let's do simultaneous
multiply the secondequation by 5
[tex]5r + 4d = 32[/tex]
[tex]5r + 30d = 110[/tex]

Solve for x.
1/4 + 1/2 + x = −3/4
Enter your answer in the box.
x =
Answer:
x=-1.5
Step-by-step explanation:
To solve for x, you need to rearrange so the x is on one side of the "=" by itself.
So To do that, first you need to subtract 1/4 on both sides of the "=". This leaves you with 1/2+x=-3/4-1/4. You can simplify the -3/4-1/4 to -1 (-4/4). So, you now have 1/2+x=-1.
The next step is to subtract 1/2 on both sides of the "=". This leaves you with x=-1-1/2. Again, you can simplify the -1-1/2 to -3/2 which can be written as -1.5. So, you now have x=-1.5, which is the final answer.
The question may ask you to write your answer in the form of a fraction, in which case your answer x=-3/2. If the questions wants it written as a mixed number, your answer would be -1 1/2.

If the temperature is 30, what is the temperature in Fahrenheit?
Answer:
The answer is 86° Fahrenheit.
Step-by-step explanation:
The equation for converting between Fahrenheit and Celsius is °F = 1.8 x °C + 32. So you would just plug 30 in for the °C.
°F = 1.8 x 30° + 32.
°F = 54 + 32
°F = 86°
Answer:
30ºC = 86ºF
Step-by-step explanation:
The temperature T in degrees Fahrenheit (ºF) is equal to 30 degrees Celsius (ºC) times 9/5 plus 32:
T(ºF) = 30ºC × 9/5 + 32 = 86ºF

medi Shashi Rimoko earns $620 per week as a chef. He has group
medical and dental insurance. Medical coverage costs $9,560
a year and dental coverage costs $172 a year. The restaurant
pays 80% of the medical and 65% of the dental insurance. How
much is deducted each week for insurance
Out of the weekly amount that Shashi Rimoko makes, a deduction of $37.93 is made for insurance.
The total Medical cost is $9,560 and out of this, the amount paid by Shashi per year is:
= Amount x (1 - percentage paid by restaurant)
= 9,560 x ( 1 - 80%)
= $1,912
The amount he pays for Dental coverage is:
= Amount x (1 - percentage paid by restaurant)
= 172 x (1 - 65%)
= $60.20
The total amount he pays for insurance per year is:
= Medical + Dental
= 1,912 + 60.20
= $1,972.20
The weekly deduction is:
= Year amount / No. of weeks in year
= 1,972.20 / 52
= $37.93
In conclusion, $37.93 is deducted from his paycheck every week.

Write the slope-intercept equation of the line passing through (4,6) and (0,-8).
Answer:
Answer:
[tex]y=\frac{7}{2} x -8[/tex]
Step-by-step explanation:
We are given that a line contains these 2 points: (4,6) and (0,-8), in slope-intercept form
Slope-intercept form is given as y=mx+b, where m is the slope and b is the value of y at the y intercept
First, we need to find the slope of the line
The slope can be calculated using the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points
Even though we have 2 points, let's label their values to avoid any confusion and mistakes when calculating:
[tex]x_1=4\\y_1=6\\x_2=0\\y_2=-8[/tex]
Now substitute into the formula
m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m=[tex]\frac{-8-6}{0-4}[/tex]
Subtract
m=[tex]\frac{-14}{-4}[/tex]
Divide
m=[tex]\frac{7}{2}[/tex]
The slope is 7/2
Here is the equation of the line so far:
[tex]y=\frac{7}{2}x + b[/tex]
We now need to find b
As the equation passes through (4,6) and (0,-8), we can use either one of them to help solve for b.
Taking (4,6) for instance:
[tex]6=\frac{7}{2}(4) + b[/tex]
Multiply
[tex]6=14 + b[/tex]
Subtract
-8 = b
The equation therefore is:
[tex]y=\frac{7}{2} x -8[/tex]

The solution of the inequality ( - 5 / 2 ) ( 3x- 2 )< 6 - 2x. will be x < ( 18 / 11 ).
What is inequality?
inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.
Given inequality will be solved as below:-
( - 5 / 2 ) ( 3x - 2 ) < 6 - 2x
Multiply the other hand by 2 and solve further.
( - 5 ) ( 3x - 2 ) < 2 ( 6 - 2x )
( - 5 ) ( 3x - 2 ) < ( 12 - 4x )
Take like terms to the same side and solve.
-15x + 30 < 12 - 4x
-15x + 4x < 12 - 30
-11x < - 18
x < 18 / 11
Therefore, the solution of the inequality ( - 5 / 2 ) ( 3x- 2 )< 6 - 2x. will be x < ( 18 / 11 ).

Hey could some one please answer this question ?
Rakim's goal is to have at least $500 in his checking
account at the end of the year. The table shows his
activity for the month of January. Will Rakim make his
goal if the month of January's activity is representative
of how much he will save and spend each month?
Explain.
Answer:
Each month he will save $ 50
Each month he will spend $1,250
Raking will have $600 in his checking account at the end of the year.
Step-by-step explanation:
1300 - 500 - 750 = $50
$50 x 12 month = $600
The required amount Rakim saves and sped each month is $50 and $1250.
Given that,
Rakim's goal is to have at least $500 in his checking account at the end of the year. The table shows his activity for the month of January. Will Rakim make his goal.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
According to the question,
Total money he has = 1300
Total money spend = 750 + 500 = 1250
Money he save = 1300 - 1250 = 50
For the condition of at end of the year he must have at least $500
So,
Yearly saving = 50 × 12 = $600, which greater than $500.
The required amount Rakim saves and sped each month is $50 and $1250.

Answer:
(- 3, 0 ) and (5, 0 )
Step-by-step explanation:
To find the x- intercepts let f(x) = 0 , that is
x² - 2x - 15 = 0
Consider the factors of the constant term (- 15) which sum to give the coefficient of the x- term (- 2)
The factors are - 5 and + 3 , since
- 5 × 3 = - 15 and - 5 + 3 = - 2 , then
(x - 5)(x + 3) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 5 = 0 ⇒ x = 5
x + 3 = 0 ⇒ x = - 3
The x- intercepts are (- 3, 0 ) and (5, 0 )
