what is the complement of 14 17'
The complement of the angle 14° 17' would be; 75° 43'
What is the Complement of the Angle?We want to find the complement of the angle 14° 17'
The complement of 14° is the angle that when added to 14° forms a right angle (90° ).
Now, when an apostrophe is found in the word angles, it means 'angular minutes, while " denotes angular seconds. For instance, "75degree 20′ 39" means "75 degrees, 20 minutes, and 39 seconds."
Thus, 14° 17' means 14 degrees, 17 minutes.
Now, 17 minutes when converted to degree is;
17/60 degrees = 0.283. Thus; 14° 17' = 14.283
Now, the complement of 14° 17' would be;
90 - 14° 17' = 75° 43'

Kadeem has $680 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.
• He buys a new bicycle for $470.65.
• He buys 2 bicycle reflectors for $7.87 each and a pair of bike gloves for $15.18.
• He plans to spend some or all of the money he has left to buy new biking outfits for $50.98 each.
Write and solve an inequality which can be used to determine x, the number of outfits Kadeem can purchase while staying within his budget.
Total money with Kadeem = $680
Money spent by him on a new bicycle = $470.65
Money left with him after buying a new bicycle = 680 - 470.65 = 209.35
Money spent by him on 2 bicycle reflectors = 7.87*2 = $15.74
Money left with him after buying reflectors = 209.35 - 15.74 = $193.61
Money spent by him on bike gloves = $15.18
Money left with him after buying biking outfits: 193.61 - 15.18 = $178.43
Cost of each outfit = $50.98
Let the number of outfits Kadeem can buy be x, therefore formulating the equation we get:
50.98x< = 178.43
x< = 3.5
So, Kadeem can buy 3 outfits while staying within budget

I need to estimate then find the product 416x9 =3,744 why is the estimate 3,600?
First of all we know about the Estimation.
What is the Estimation?
To estimate the result of multiplication (product), round the numbers to some close numbers that can easily multiply . One method of estimation is to round all factors to the biggest digit (place value) they have.
General rule for rounding:
1 ) If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.
2 ) If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.
So the last digit of number is 44 which is less then 50 so the number is down to its 10's.
thats the reason why when we estimate the product of 416x9 =3,744 is 3,600.

Answer: Graph D
The inequality solves to [tex]\text{x} \le 36[/tex]
=====================================================
Explanation:
The goal is to solve for x.
Multiply both sides by 2 to go from
[tex]\frac{1}{2}\text{x} \le 18[/tex]
to
[tex]\text{x} \le 36[/tex]
The inequality sign does not flip. It would only do so if you multiplied or divided both sides by a negative number.
The graph will have a closed filled in circle at 36, with shading to the left. This is to visually show the set of all x values that are 36 or smaller. The endpoint 36 is included in the solution set (an open hole would be used if you wanted to exclude it from the solution).

Solve for n
s = 4n+4v
We get the equation in terms of n as n = s / 4 - v.
Equation:
An equation is an expression with an equal sign.
For example:
3 x + 4 y = 5
2 x + 5 y = 9 etc.
We are given an equation:
s = 4 n + 4 v
We have to solve this for n.
First we will subtract 4 v from both sides:
s - 4 v = 4 n + 4 v - 4 v
s - 4 v = 4 n
4 n = s - 4 v
Now divide both the sides by 4:
4 n / 4 = (s - 4 v) / 4
n = s / 4 - v
Therefore, we get the equation in terms of n as n = s / 4 - v.

Step-by-step explanation:
In the problem you are given two pairs of numbers. These are both a pair of inputs and outputs, (x, y):
(390, 3100) also,
(490, 3700)
Write an equation by finding and filling in m and b in the following equation:
y = mx + b
To find m, which is the slope of the line, subtract y-y and put that on top. Then subtract x-x and put that on the bottom. See image.
Next, find b by use EITHER pair of numbers to find b.
I used (390, 3100).
see image.
m = 6 and b = 760
Fill these into
y= mx + b
y = 6x + 760
In case they ask, this means each calculator takes $6 to make and it costs $760 to set up your operation even before you have made any calculators.

The perimeter of a rectangular window is 324 cm .
If the width of the window is 73 cm , what is its length?
Answer:
The length is 89 cm============================
Perimeter equationP = 2(l + w), where
P- perimeter, l- length, w- widthGivenP = 324 cm,w = 73 cmFind the value of l:
324 = 2( l + 73)l + 73 = 324/2l + 73 = 162l = 162 - 73l = 89Answer:
L = 89 cm
Step-by-step explanation:
Formula we use,
→ P = 2(L + W)
Then the value of its length is,
→ P = 2(L + W)
→ 324 = 2(L + 73)
→ 324 = 2L + 146
→ 2L = 324 - 146
→ L = 178/2
→ [ L = 89 cm ]
Hence, the length is 89 cm.

Step-by-step explanation:
It is given that, Diane got a prepaid debit card with $25 on it. For her first purchase with the card, she bought some bulk ribbon at a craft store. The price of the ribbon was 12 cents per yard.
Now, if after that purchase there was $22.84 left on the card, let's calculate how many yards of ribbon did Diane buy in total and for that we need to;
Furthermore, based on the given conditions, we will be formulating the following;
=> (25-22.84) / 12
=> 2.16/12
=> 216/100 × 1/12
=> 9/25 × 1/2
=> 9 / (25×2)

Answer:
8. HI = 25 cm
9. HJ = 27.5 cm
10. IK = 5.5 cm
Step-by-step explanation:
Given segments JK=3 cm and IJ=2.5 cm of 30.5 cm length HK having points H, I, J, K in sequence, you want to find missing segment lengths.
Segment sum theoremThe segment sum theorem tells you the length of a line segment is the sum of the lengths that make it up. That means ...
HI +IJ +JK = HK
This lets you find the lengths of the various segments without concerning yourself with the value of x.
8. HIUsing the given lengths in the above sum, we have ...
HI +2.5 +3 = 30.5
HI = 30.5 -5.5 = 25
The length of HI is 25 cm.
9. HJThe overall length is the sum of its parts:
HI +IJ = HJ
25 +2.5 = 27.5 = HJ
The length of HJ is 27.5 cm.
10. IKThe overall length is the sum of its parts:
IJ +JK = IK
2.5 +3 = 5.5 = IK
The length of IK is 5.5 cm.

In case you actually want to find x, you can find it from ...
HI = 3x +4
25 = 3x +4
21 = 3x . . . . . . subtract 4
7 = x . . . . . . . divide by 3.
