Two sides of a triangle have the following measures. Find the range of possible measures for the third side.
12, 8
Answer:
between 4 and 20......................
The number should be bigger than difference of both sides and smaller than sum of both sides.
So
12+8=20
12-8=4
So it should be 4<x<20
which means between 4 and 20
Do you really have brown eyes?
Answer:
4 < x < 20
Step-by-step explanation:
Given 2 sides of a triangle then the third side x is in the range
difference of 2 sides < x < sum of 2 sides , that is
12 - 8 < x < 12 + 8
4 < x < 20 ← range of values for third side
use the substitution method to solve.

Answer:
width = 40 cm
Step-by-step explanation:
Since the pentagons are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{4x}{x}[/tex] = [tex]\frac{48}{x+2}[/tex] ( cross- multiply )
4x(x + 2) = 48x ← distribute left side
4x² + 8x = 48x ( subtract 48x from both sides )
4x² - 40x = 0 ← factor out 4x from each term on left side
4x(x - 10) = 0
Equate each factor to zero and solve for x
4x = 0 ⇒ x = 0
x - 10 = 0 ⇒ x = 10
However, x > 0 then x = 10
Thus width = 4x = 4 × 10 = 40 cm
How much of an alloy that is 10% copper should be mixed with 600 ounce of an alloy that is 70%copper in order to get an alloy that is 30%copper?
Answer:
1200 ounces
Step-by-step explanation:
How much of an alloy that is 10% copper should be mixed with 600 ounce of an alloy that is 70%copper in order to get an alloy that is 30%copper?
Let us represent
Number of ounce of 10% copper = x
Hence, our Equation =
x × 10% + 600 × 70% = (x + 600) × 30%
0.1x + 420 = (x + 600)0.3
0.1x + 420 = 0.3x + 180
Collect like terms
0.3x - 0.1x = 420 - 180
0.2x = 240
x = 240/0.2
x = 1200 ounces

A shop sold 250 CDs last week. The sales of CDs increased by 16% this week. Find the sales volume of this week.
Answer:
Cds sold= 290
Step-by-step explanation:
Giving the following information:
A shop sold 250 CDs last week. The sales of CDs increased by 16% this week.
To calculate the number of CDs sold this week, we need to use the following formula:
Cds sold= Cds sold last week*(1 + percentage increase)
Cds sold= 250*1.16
Cds sold= 290

What are the coordinates of the point on the directed line segment from (-6,9) to
(4, -1) that partitions the segment into a ratio of 1 to 4?
Answer:
Step-by-step explanation:
difference of x-coordinates = 4-(-6) = 10
difference of y-coordinates = -1-9 = -10
partition the differences into a ratio of 1:4
10 × 1/(1+4) = 2
-10 × 1/(1+4) = -2
(-6+2,9-2) = (-4,7)
Blake bought a new car. He borrowed $12,500 from the bank. After 4 years he had paid off the loan and paid $1500 in interest. What rate did he borrow at? Include the steps you used to solve the problem and your answer
Answer:
3%
Step-by-step explanation:
Blake bought a new car. He borrowed $12,500 from the bank. After 4 years he had paid off the loan and paid $1500 in interest. What rate did he borrow at?
This is a simple interest question
The formula to find the rate is given as:
Equation:
r = (1/t)(A/P - 1)
t = time = 4 years
P = Principal = $12500
I = Simple Interest = $1500
A = Total Amount = Principal + Simple Interest = $12500 + $1500
= $14000
Calculation:
Solving our equation:
r = (1/4)((14000/12500) - 1) = 0.03
r = 0.03
Converting r decimal to R a percentage
R = 0.03 * 100 = 3%/year

If x^2 + y^2 = 10 and xy = -3, what is the value
of (x - y)^2?
A) 12
B) 16
C) 20
D) 25
Answer:
Step-by-step explanation:
[tex]xy=-3,\ x=-\frac{3}{y}\\ \\ x^2+y^2=10\\ \\ \frac{9}{x^2}+x^2=10\\ \\ x^4+9=10x^2\\ \\ x^4-10x^2+9=0\\ \\ (x^2-1)(x^2-9)=0\\ \\ (x-1)(x+1)(x-3)(x+3)=0\\ \\ x=-3,-1,1,-3\ y=1,3,-3,-1\\ \\ (x-y)^2\\ \\ (-3-1)^2=(-4)^2=16[/tex]
A quadratic function, f(x) = x2 + bx + 9, is such that there is only one real root. Which of the following are possible values of b?
I. b = 2
II. b = 6
III. b = -6
IV. b = -2
A. I, II, III, and IV
B. I and IV only
C. II and III only
D. I only
Answer:
C
Step-by-step explanation:
Remember that we can use the discriminant to determine the amount of roots that a quadratic function has.
If the determinant equals 0, then we only have one real root.
Our function is given by:
[tex]f(x)=x^2+bx+9[/tex]
Then the discriminant will be:
[tex]\Delta = b^2-4(1)(9)=b^2-36[/tex]
We only have one real root, thus our discriminant must be 0:
[tex]0=b^2-36[/tex]
Solve for b:
[tex]b^2=36[/tex]
Thus:
[tex]b=\pm 6[/tex]
The answer is both II and III.
The final answer, then, is C.
