What is the perimeter of a square if its area is 50 cm??
Answer:
28.4 (rounded)
Step-by-step explanation:
7.1 times 7.1 is 50. To calculate area, you need to multiply 2 of the sides. so, that is the side length.
then, you multiply it by 4 for all four sides. that would be 28.4.
Answer:
54 or 30
Step-by-step explanation:
Perimeter is adding all the sides together. Area is multiplying LxW and 50 can be gotten by multiplying 5 by 10, or 25 by 2. So if you went by 5x10, both lengths would be 5 and the widths would be 10 or vice versa. Same goes for if you multiplied 25 by 2.

Kevin claims that the smallest angle of rotation through the center of a regular 15-gon that carries it onto itself is 156° since 180(15−2)15=156. Decide if Kevin is correct. If Kevin is correct, enter 156 below. If Kevin is incorrect, enter the correct value of the smallest angle of rotation through the center of a regular 15-gon that carries it onto itself.
Answer:
Step-by-step explanation:
The formula for calculating the interior angle of a polygon is expressed as;
sum of internal angle = (n-2)180 where;
n is the number of sides of the polygon in consideration.
Given a 15 sided polygon, n = 15
sum of internal angle = (15-2)180
sum of internal angle = (13)180
sum of internal angle = 2340
Hence kevin is wrong, the correct answer is 2340

Jan says that 2 is between 0 and 3/4 on a number line. Do you agree? Why or why not?
Answer:
No
Step-by-step explanation:
2 is a positive whole number with a value greater than 1. 3/4 is NOT greater than 1. So 2 is greater than both 0 AND 3/4 and cannot be between the two numbers.
No, Jan is wrong because 2 is not in between 0 and 3/4 on a number line.
What is Number line?
Number line is a horizontal line where numbers are marked at equal intervals one after another form smaller to greater.
Given that;
Jan says that 2 is between 0 and 3/4 on a number line.
Here, The numbers on the number line are 0 and 3/4.
⇒ 3 / 4 = 0.75
So, We get;
⇒ 2 > 0
And, 3/4 < 2
Thus, The number 2 is not in between 0 and 3/4 on a number line.

How the equation changes
Flip over x-axis: __________ the entire function by a negative number
Flip over y-axis: __________ every x in the function by a negative number
Answer:
When you flip over the the x-axis, the y-coordinate becomes the additive inverse. I.e. ; if I flipped over the x-axis, a (x,4) would become (x,-4). When you flip over the y-axis the x becomes the additive inverse. (x,4) will become (-x,4)

Does the system of equations below have no solution, 1 solution, or infinite solutions
= 2 − 1
= 2 + 4
Answer:
no solution
Step-by-step explanation:
y = 2x - 1 → (1)
y = 2x + 4 → (2)
substitute y = 2x - 1 into (2)
2x - 1 = 2x + 4 ( add 1 to both sides )
2x = 2x + 5 ( subtract 2x from both sides )
0 = 5 ← not possible
This indicates the system has no solution

there is a loss of 20% by selling a photocopy machine for rs 60000 at what price will the machine be sold to gain 12% find it
Answer:
Step-by-step explanation:
Loss is 20%
S.P=Rs60000
C.P=S.P*100/100-loss%
=60000*100/80=Rs75000
So he brought is at Rs75000
Now he wants 12% profit
So
S.P=(100+profit%)/100*C.P
=100+12/100*75000
=112/100*75000=Rs 84000
He will have to sell Rs14000 more to gain profit of 12%

y= 30,000x - 2000
y= -2000x +30,000
Answer:
y = -2000x + 30,000 is the correct answer.
Step-by-step explanation:
For slope intercept equation we first determine the intercept on the axis.
The intercept is a constant value, c, in the slope intercept equation.
In this case, the constant value is 30,000.
Our height, y, is directly proportional to minute,x, taken to descend.
y = mx + c
M is the slope/ gradient which is -2000 since the airplane is descending.
Since the plane descends 2000 feet per minute, its height after 1 minute should be:-
y = -2000(1) + 30,000
y = 28,000
This calculation confirms our above answer.
Your annual salary is $28,460 your State personal deductions total $88 for a weekly pay period. The state tax rate is 3.6% of taxable income. The city rate is 1.7% of gross pay. Medical and group life insurance is paid by the company. Social security and Medicare are withheld .Union dues are $156 per year. FIT is $67 per pay period what is your net pay for each weekly pay period
Answer:
First, in one year you win:
$28,460
Now yearly we can subtract:
3.6% for the taxable income
1.7% for the gross pay:
(Those apply to the complete annual salary)
3.6% + 1.7% = 5.3%
This in decimal notation is 0.053, then paying those two things we have left:
$28,460*(1 - 0.053) = $26,951.62
Now we need to subtract the union dues, which are $156 per year.
$26,951.62 - $156 = $26,795.62
Now, this is yearly, and we want to know the weekly pay.
In one year we have 365 days.
One week has 7 days.
Then in one year, we have:
365/7 = 52.14 weeks.
Then the pay per week is:
$26,795.62/52.14 = $513.92
And now, each week we must pay $88 for state personal deductions, and $67 for FIT.
Then we have:
$513.92 - $88 - $67 = $358.92
Then the net pay for each weekly pay period is: $358.92

What is the area of this composite figure
189.25 in2
228.5 in2
150 in2
78.5 in2
Answer:
189.25 in²
Step-by-step explanation:
First, let us find the area of the rectangle.
Area = Length × Width
= 15 in × 10 in
= 150 in²
Then let us find the area of the semicircle.
Area = [tex]\frac{1}{2}[/tex] × π r²
= [tex]\frac{1}{2}[/tex] × 3.14 × 5 × 5
= 0.5 × 3.14 × 25
= 1.57 × 25
= 39.25 in²
Now let us find the total area of the composite figure.
Total area = Area of the rectangle + Area of the semi-circle.
= 150 in² + 39.25 in²
= 189.25 in²
