Area of square = side * side
= 4 * 4
= 16 sq.ft
Area of triangle = [tex]\frac{1}{2}*base*height\\[/tex]
[tex]= \frac{1}{2}*4*2\\\\= 4 sq.ft[/tex]
Area of the figure = area of square + area of triangle
= 16 + 4

1. a circle has a circumfrance 88cm find its radius
2.a sector with angle 45 degrees has ab arc length 44cm find it radius and perimeter speratly
pls answer asap i will give u the brainliest
Step-by-step explanation:
Number 1
Circumference = 88cm
Circumference = 2πr
2πr = 88
πr = 88/2
πr = 44
22r/7 = 44
22r = (44 × 7)
r = (44 × 7)/22
r = 2 × 7
r = 14cm
Number 2
Length of arc = 44cm
Angle = 45°
L = ∅/360 × 2πr
44 = 45/360 × 2πr
44 = ⅛ × 2πr
44 = ¼ × πr
πr = 44 × 4
22r/7 = (44 × 4)
22r = (44 × 4 × 7)
r = (44 × 4 × 7)/22
r = 2 × 4 × 7
r = 2 × 28
r = 56cm
Perimeter = L + 2r
P = 44cm + 2(56cm)
P = 44cm + 112cm
P = 156cm

The ratio of the measures of the angles in a triangle is 11:2:5 find the measures of the largest angle
9514 1404 393
Answer:
110°
Step-by-step explanation:
The total of the ratio units is 11 +2 +5 = 18. These stand for the total of angles, 180°, so each ratio unit stands for 180°/18 = 10°.
The largest angle is 11 ratio units, or 11×10° = 110°.
Nathan and his children went into a grocery store and he bought $12 worth of apples and bananas. Each apple costs $1.50 and each banana costs $0.60. He bought a total of 11 apples and bananas altogether. By following the steps below, determine the number of apples, x,x, and the number of bananas, y,y, that Nathan bought.
Determine three ways to have a total of 11 apples and bananas:
Step-by-step explanation:
X= apple y=banana 1 apple cost $1.50 and a1 banana cost $0.60 nathan buy 11banana and apple 1.50×11 = 16.5 0.60×11= 6.6. 16.5 +6.6 =23.1
The wholesale price for a dozen pairs of socks is $4.30. The retail price for the same dozen pairs of socks is $9.25. What is the mark-up the retailer used? Write your answer as a complete sentence.
Answer:
the mark up used by the retailer is 115.12% of the wholesale price
Step-by-step explanation:
Mark-up is the percentage increase of the retail price over the wholesale price
Mark-up = (difference between retail and whole sale price / retail price ) x 100
difference between retail and whole sale price = $9.25 - $4.30 = $4.95
(4.95 / 4.3) x 100 = 115.12%.

Step-by-step explanation:
The sign shows that any number that is equal to, or more than, 36 is a valid answer. It can't be 3 because 3 x 9 is 27, and 27 is less than 36, so that wouldn't be true. 4 x 9 is 36, and 36 = 36, so that would be true, and obvoiusly all the other numbers that are over 4, when multiplied by 9, will equal more than 36, so they are all correct, except for the 3 and none answers. I hope this helps you out :)

The interquartile range is (the middle of the upper half) - (the middle of the lower half). To find this list out all of the values and find the median, then find the center of the upper half and the lower half.
1 2 2 3 3 3 4 4 5 6 Here I have made a small diagram of how you were to find the middle of each half with the underline being each half, the bold being the sides for each half, and the italicized being the value. For this question the middle of the upper half is 4 and the middle of the lower half is 2, so 4-2 = 2.

The amount y (in dollars) that you earn by working x hours is represented by the equation y = 9x. A) What is the slope? B) What does the slope mean? Interpret! C) How much money would you make if you worked 40 hours?
Answer:
360 dollars
Step-by-step explanation:
Equation;
y = 9x
A) What is the slope?
The slope in an equation is the coefficient of the x variable. In this question, the slope is 9.
B) What does the slope mean? Interpret!
The slope shows the relationship between the x and y values.
This means that for every single unit change of x, y changes by 9 times.
C) How much money would you make if you worked 40 hours?
x = working hours
y = Amount
y = 9 (40) = 360 dollars
Find an nth-degree polynomial function with real coefficients satisfying the given conditions. If you are using a graphing utility, use it to graph the function and verify the real zeros and the given function value.
n=3
4 and 4i are zeros;
f(-1)=85
F(x) = ________
Givem that at n = 3: 4 and 4i are zero;
Then;
[tex](x - 4)(x - 4i)(x + 4i) \: (x - 4)( {x}^{2} - ( {4i)}^{2} \\ (x - 4)(x - 4i)(x + 4i) \: (x - 4)( {x}^{2} + 16) \\ (x - 4)(x - 4i)(x + 4i) \: {x}^{3} + 16x - {4x}^{2} - 64 \\ (x - 4)(x - 4i)(x + 4i) \: {x}^{3} - {4x}^{2} + 16x - 64[/tex]
Hence the function is:
[tex]f = {x}^{3} - {4x}^{2} + 16x - 64[/tex]
Scarlett went shopping for a new pair of pants. Sales tax where she lives is
4%. The price of the pair of pants is $41. Find the total price including tax.
Round to the nearest cent.
Answer:
39.36
Step-by-step explanation:
1% of 41 is .41, so you multiply that by 4 to get 1.64. Then do 41-1.64=39.36
The total price including tax is $42.64
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
Price of pants= $41
Sales tax= 4%
So, the tax is
= 41 x 4%
= 41 x0.04
= $1.64
Now, the price of pants after tax
= 41 + 1.64
= $42.64
Hence, the total price including tax is $42.64

-(1/2) or -0.5
Step-by-step explanation:
select two coordinates. for example, (2,2) and (4,1).
do (y2 - y1) ÷ (x2 - x1).
in this case, (1 - 2) ÷ (4 - 2). you should end up with -(1/2), or -0.5
