sharia has a full time job and earns 475$ each week but she starts looking for ways to increase her weekly earnings . sharia finds a part-time job which would pay 11$ per hour. How many hours would sharia need to work each week at the part-time job in order to raise total weekly income to at least $600?
Answer:
12 hours
Step-by-step explanation:
Full time job:
Earning per week = $475
Part time job :
Earning per hour = $11
Number of working hours per week at per time job to increase weekly earning to atleast $600 ;
Let number of hours = h
Full time earning + earning per hour * (number of hours) ≥ 600
$475 + ($11 * h) ≥ 600
$475 + $11h ≥ 600
11h ≥ 600 - 475
11h ≥ 125
h ≥ 125 / 11
h ≥ 11.36
Hence, sharia will need to work for 12 hours per week
Find x and y so the quadrilateral is a parallelogram.
9514 1404 393
Answer:
x = 7y = 4Step-by-step explanation:
The diagonals of a parallelogram cross at their midpoints. This means the segments of each diagonal are equal in length:
RT = PT
x = 5x -28
28 = 4x . . . . . add 28-x
7 = x . . . . . . . .divide by 4
__
QT = ST
5y = 2y +12
3y = 12 . . . . .subtract 2y
y = 4 . . . . . . divide by 3
The values of x and y that make the figure a parallelogram are x=7 and y=4.

During a food drive, a local middle school collected 8,872 canned food items. Each of the 33 classrooms that participated in the drive donated about the same number of items. Estimate the number of items each classroom donated.
Each class donated about_________ cans
Answer: 321
Your explanation
There where 28 classrooms that donated. If we are to estimate the total, then we must round the canned items. They're 8982 canned items. If you round that number, you get 9000. So you want to divide 9000 and 28.

Solve 7x=56 what is x?
Answer:
8
Step-by-step explanation:
X=56÷7=8
By moving 7 to other side
And change the sign to divide
Becz if it multiplication it will change to divide and if plus it will change it sign to negative
The value of x in the equation 7x = 56 is 8.
To solve the equation 7x = 56 for x, we can isolate x by dividing both sides of the equation by 7.
7x/7 = 56/7
Simplifying:
x = 8
Therefore, x is equal to 8.

Find the values of X and why in the following equation.
(x+yi)+(4+9i)=9-4i
Answer:
The values of x and y are x = 5 and y = -13 ⇒ B
Step-by-step explanation:
If the complex numbers are A = (a + bi) and B = (c + di), then
A + B = (a + c) + (b + d)i
(a + c) is the real part(b + d) is the imaginary partLet us solve the question
∵ (x + yi) + (4 + 9i) = 9 - 4i
→ Add the real parts and the imaginary parts on the left side
∵ x, 4 are the real parts, and y and 9 are the imaginary parts
∴ (x + 4) + (y + 9)i = 9 - 4i
→ Compare the two sides, and equate the like terms
∵ 9 is the real part and -4 is the imaginary part
∴ x + 4 = 9
→ Subtract 4 from both sides
∴ x + 4 - 4 = 9 - 4
∴ x = 5
∵ y + 9 = -4
→ Subtract 9 from both sides
∵ y + 9 - 9 = - 4 - 9
∴ y = -13
Answer:
x = 5 and y = -13

Answer:
The function y = 5 [tex](.98)^{x}[/tex] represents exponential decay
The percentage rate of change is 2%
Step-by-step explanation:
The formula of the exponential growth is y = a [tex](1+r)^{x}[/tex], where
a is the initial valuer is the rate of increase in decimal ⇒ (1 + r) > 1The formula of the exponential decay is y = a [tex](1-r)^{x}[/tex], where
a is the initial valuer is the rate of decrease in decimal ⇒ (1 - r) < 1Let us solve the question.
∵ y = 5 [tex](.98)^{x}[/tex]
→ Compare it with the forms above
∴ a = 5
∵ The rate of change is .98
∵ .98 < 1
→ That means the rate of change is decreasing
∴ The function y = 5 [tex](.98)^{x}[/tex] represents exponential decay
→ From the 2nd form above
∵ (1 - r ) = .98
→ Subtract 1 from both sides
∴ 1 - 1 - r = .98 - 1
∴ - r = - .02
→ Divide both sides by -1
∴ r = .02
→ Multiply it by 100% to change it to a percentage
∵ .02 × 100% = 2%
∴ r = 2%
∴ The percentage rate of change is 2%

Answer:
Perimeter: 52 Area: 181-16i?
Step-by-step explanation:
Perimeter
The formula for perimeter is 2l+2w, so you plug in the binomials they give you:
2(11-4i)+2(15+4i)
expand:
22-8i+30+8i
combine like terms (which cancels out 8i and -8i):
22+30=52
Area
"i" is not a real number and thus should not be part of the area here, meaning this answer as it is is wrong and I don't know how one would change that.
Here's what I did to get 181-16i, in any case:
The formula for area is l*w, so I plugged in the numbers:
(11-4i)(15+4i)
expanded:
165+44i-60i-16i*i
and combined like terms:
181-16i
*i is [tex]\sqrt{-1}[/tex], so [tex]i^{2}[/tex]=-1 and -1*-16=16.
