Three years ago, Daniel bought a baseball card for $20. The baseball card gains a value of $10 each year for the next three years. A friend offers to buy the baseball card foe twice the value, how much would the friend pay?
Answers
Answer:
The friend would pay $100
Step-by-step explanation:
The price of the card was $20 when Daniel bought it, it gained a value of $10 every year,
since Daniel bought it 3 years ago we will add $30 to $20 as the value increased by $10/year
so the price becomes $50, but his friend says he'll pay twice the value so,
$50×2= $100

Answer:
[tex]\frac{6247}{375000}[/tex]
Step-by-step explanation:
Hey, Ace here!
We have the equation [tex](6*10)^{-1} - (5*10)^{-3}[/tex]
Let's simplify by doing the parenthesis first:
[tex]60^{-1} - 50^{-3}[/tex]
According to our exponent rules, [tex]a^{-b}=\frac{1^{b}}{a^{b}}[/tex]
So let's simplify:
[tex]\frac{1^{1}}{60^{1}} - \frac{1^{3}}{50^{3}}[/tex]
Simplify further:
[tex]\frac{1}{60} - \frac{1}{125000}[/tex]
Find a common denominator (which, yes, is a pain):
[tex]\frac{1*6250}{60*6250} - \frac{1*3}{125000*3}[/tex]
Simplify:
[tex]\frac{6250}{375000}-\frac{3}{375000}[/tex]
Now perform the subtraction:
[tex]\frac{6247}{375000}[/tex]

What is important to remember when multiplying radicals?
Answers
Answer:
A radical is basically a fractional exponent and is denoted by the radical sign (√). The expression x2 means to multiply x by itself (x × x), but when you see the expression √x, you're looking for a number that, when multiplied by itself, equals x. Similarly, 3√x means a number that, when multiplied by itself twice, equals x, and so on. Just as you can multiply numbers with the same exponent, you can do the same with radicals, as long as the superscripts in front of the radical signs are the same. For example, you can multiply (√x × √x) to get √(x2), which just equals x, and (3√x × 3√x) to get 3√(x2). However, the expression (√x × 3√x) can't be simplified any further.
This equation has one solution.

Answers
Answer: -16/3
Step-by-step explanation:
[tex]3(x - 2) + 4x = 10(x + 1)\\3x - 2(3) + 4x = 10x +1(10)\\3x - 6 + 4x = 10x + 10\\7x - 6 = 10x + 10\\7x - 10x = 10 + 6\\-3x = 16\\x = \frac{16}{-3} =-\frac{16}{3}[/tex]
Answer:
-16/3
Step-by-step explanation:
3(x – 2) + 4x = 10(x + 1)
Step 1 distribute the 3 to the x and -2
Outcome: 3x - 6 + 4x = 10(x + 1)
Step 2 distribute the 10 to the x and 1
Outcome: 3x - 6 + 4x = 10x + 10
Step 3 combine like terms
Outcome: 7x - 6 = 10x + 10
Step 4 add 6 to both sides
Outcome: 7x = 10x + 16
Step 5 subtract 10x from both sides
Outcome: -3x = 16
Step 6 divide both sides by -3
Outcome: x = -16/3

the letter v has an unknown value. If you multiply v by 16, the product is 4.what is the value of v?
Answers
Answer:
v = 0.25
Step-by-step explanation:
v = ?
v x 16 = 4 (given)
v = 4/16
v = 0.25
Checking:
[ 0.25 x 16 = 4]
Answer:
1/4 or 0.25 (as a decimal)
Step-by-step explanation:
We know that v has an unknown value.
When it is multiplied by 16, we would get the product.
Turn it into an equation:
16x = 4
Find x:
4 ÷ 16 = 0.25 or 1/4
Now we’ve find x:
16 x 1/4 = 4
Which is a true equation
So x equals 0.25 or 1/4 (as a fraction)

Answers
Answer:
Programmed
Step-by-step explanation:
Programmed Decisons may be classified as those actions which are routinely carried out or performed based on existing rules and protocol. In programmed decision making, the rules are in place, therefore once the criteria or requirement for which the rule or routine is to be enforced arises, programmed Decisons are made. In the scenario, the superintendent required that a programmed Decison be made in cases or situations where enrollment increases by 35 student beyond capacity, Hence, with this, every time this occurs the additional teachers will be hired.

Find the equation of the perpendicular bisector of the side QR
Answers
Answer:
Step-by-step explanation:
Find the slope of QR. From that we can find the the slope of the line perpendicular to QR.
Q(-2, -5) & R(8,1)
[tex]Slope \ = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{1-[-5]}{8-[-2]}\\\\=\frac{1+5}{8+2}\\\\=\frac{6}{10}\\\\=\frac{-3}{5}[/tex]
So, the slope of the line perpendicular to QR = -1/m - 1÷ [tex]\frac{-5}{3} = -1*\frac{-3}{5}=\frac{3}{5}[/tex]
Bisector of QR divides the line QR to two half. We have find the midpoint of QR.
Midpoint = [tex](\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2})[/tex]
[tex]=(\frac{-2+8}{2},\frac{-5+1}{2})\\\\=(\frac{6}{2},\frac{-4}{2})\\\\=(3,-2)[/tex]
slope = 3/5 and the required line passes through (3 , -2)
y - y1 = m(x-x1)
[tex]y - [-2] = \frac{3}{5}(x - 3)\\\\y + 2 = \frac{3}{5}x-\frac{3}{5}*3\\\\y=\frac{3}{5}x-\frac{9}{5}-2\\\\y=\frac{3}{5}x-\frac{9}{5}-\frac{2*5}{1*5}\\\\y=\frac{3}{5}x-\frac{9}{5}-\frac{10}{5}\\\\y=\frac{3}{5}x-\frac{19}{5}[/tex]
Find the measure of the missing angle using exterior angle sum theorm

Assuming 145 is the exterior angle, the interior is 35. 180-145=35
Add 110 to 35 and get 145 degrees. Which leads the remaining angle 35 degrees
Answer:
35

The exterior sum theorem states the exterior angle is equal to the sum of the opposite interior angles
145 = ?+110
145 - 100 = ?

why can two prime numbers only have one common factor?

A prime number has exactly two factors, 1 and itself. For example, 13 is a prime number because the only factors of 13 are 1 and 13. The number 8 is not prime because it has four factors: 1, 2, 4 and 8. The number 1 is not a prime number because it only has one factor (itself).
(Algebra ll) Given the function below
Answers
Answer: B
Step-by-step explanation:
To find the values of x, we first need to write the function into an equation. We can derive 2 equations from the problem.
Equation 1: y=2|x+6|-4
Equation 2: y=6
Now, we can substitute.
2|x+6|-4=6
Let's solve for x.
2|x+6|-4=6 [add both sides by 4]
2|x+6|=10 [divide both sides by 2]
|x+6|=5 [subtract both sides by 6]
x=-1
Now that we know x=-1 is one of the solutions, we can eliminate C and D.
We know that the absolute value makes the number inside positive always. Therefore, let's solve for x with -5 instead.
|x+6|=-5 [subtract both sides by 6]
x=-11
Therefore, we know that B is the correct answer.
Chang knows one side of a triangle is 13 cm. Which set of two sides is possible for the lengths of the other two
sides of this triangle?
5 cm and 8 cm
6 cm and 7 cm
7 cm and 2 cm
8 cm and 9 cm
Answers
Answer:
8 cm and 9 cm
Step-by-step explanation:
Hi there!
The sum of the lengths of two sides of a triangle must always be greater than the length of the third side.
5 cm and 8 cm ⇒ 5+8=13; not greater than 13
6 cm and 7 cm ⇒ 6+7=13; not greater than 13
7 cm and 2 cm ⇒ 7+2=9; not greater than 13
8 cm and 9 cm ⇒ 8+9=17; greater than 13
Therefore, the last set of two sides is possible for the lengths of the the other two sides of this triangle.
I hope this helps!
5+8=13
6+7=13
7+2=9
8+9=17
