what is the range of possible sizes for x?
Answer:
0.5 < x < 15.5
Step-by-step explanation:
Triangle Inequality Theorem
Let y and z be two of the side lengths of a triangle. The length of the third side x cannot be any number. It must satisfy all the following restrictions:
x + y > z
x + z > y
y + z > x
Combining the above inequalities, and provided y>z, the third size must satisfy:
y - z < x < y + z
The two side lengths given in the triangle of the figure are y=8.5, z=8.0, thus the possible values of x lie in the interval
8.5 - 8.0 < x < 8.5 + 8.0
0.5 < x < 15.5
How much must be added to each of the three number 1, 11, and 23 so that together they form a geometric progression?
Answer:
49
Step-by-step explanation:
Let the three numbers be a1, a2, a3
Let the number to be added to form a geometric progression = x
a1 = 1 + x ; a2 = 11 + x ; a3 = 23 + x
For a geometric progression :
a2 = a1 * r
a2 = (1+x)r
11+x = (1+x)r - - (1)
r = (11+x) / (1+x) ---(1)
a3 = a2 * r
a3 = (11+x)r
23+x = (11+x)r - - -
r = (23+x) / (11+x) - - (2)
Equate (1) and (2)
(11+x) / (1+x) = (23+x) / (11+x)
(11+x) * (11+x) = (23+x) * (1+x)
121 + 22x + x² = 23 + 24x + x²
121 + 22x + x² - x² - 24x - 23 = 0
98 - 2x = 0
-2x = - 98
x = 98 / 2
x = 49

You decide to make and sell bracelets. The cost of your materials is $84. You charge $3.50 for each bracelet.
c. You will break even when the cost of your materials equals your income. How many bracelets must you sell to break even?
Answer:
You would need to sell 28 bracelets.
Step-by-step explanation:
28 x $3.50 = $85.48
27 bracelets is too little, 27 x $3.50 = $82.35
So it's 28

Dario is finding the percent of change from the original price of $75 to new price of $125.
Answer:
66.66666% increase (6 goes on forever, can be rounded to 66.67%)
Step-by-step explanation:
The change is 125 - 75 = 50, so it increased by 50/75 = 2/3 = 0.666666... = 66.6666%

Addison invested $440 in an account paying an interest rate of 2%
compounded continuously. Assuming no deposits or withdrawals are
made, how long would it take, to the nearest tenth of a year, for the
value of the account to reach $610?
Answer:
16.3
Step-by-step explanation:
Continuously compounding interest formula:
pe^(r*t)
we know that
440e^(.02x)=610
Sovle for x
e^.02x=1.38
.02x=ln1.38
.02x=.3267
x=16.3

The midpoint of \overline{\text{AB}} AB is M(5, 1)M(5,1). If the coordinates of AA are (3, 6)(3,6), what are the coordinates of BB?
Answer:
(7, -4)
Step-by-step explanation:
The formula for calculating midpoint is expressed as;
M(X, Y) = (x2+x1)/2, (y1+y2)/2
X = x1+x2/2
Y = y1+y2/2
Given
X = 5, Y = 1, x1 = 3, y1 = 6
Get x2
X = x1+x2/2
5 = 3+x2/2
10 = 3+x2
x2 = 10-3
x2 = 7
Get y2;
Y = y1+y2/2
1 = 6+y2/2
2 = 6+y2
y2 = 2-6
y2 = -4
Hence the coordinate of B is at (7, -4)
