Cheese sticks that were previously priced at "10 for $1" are now "4 for $1". Find each percent change
Answers
Answer:
The price per cheese stick was increased by 150%.
The amount of cheese sticks per $1.00 has decreased by 60%.
Step-by-step explanation:
The price per cheese stick was $0.10
1.00 (dollar) divided into 10 (cheese sticks) gives you 0.1, which means each cheese stick costs $0.10The current price per cheese stick is $0.25
1.00 (dollar) divided into 4 (cheese sticks) gives you 0.25, which means each cheese stick costs $0.25That means the price per cheese stick was raised by 150%.
That also means the amount of cheese sticks you could buy for $1.00 has decreased by 60%.
Which of the following constants can be added to x^2- 3x to form a perfect square trinomlal?
A. 2 1/4
B. 1 1/2
C. 4 1/2
Answers
Answer:
A 21/4
Step-by-step explanation:
When forming a perfect square trinomial you need to "complete the square".
All of the steps to completing the square when solving an equation:
1. The leading coefficient must be 1.
2. Divide b by 2.
3. Square (b/2)
4. Add (b/2)^2 to both sides to keep the polynomial balanced.
5. You can now write the perfect square trinomial and solve.
x^2 - 3x
-3/2
(-3/2)^2 = 9/4 = 2 1/4

Jennifer's grandma bought her a $50 savings bond when she was born. When Jennifer is 30 years old, the bond will have earned 110% in interest. How much will the bond be worth when Jennifer is 30 years old?
Answers
Answer:
105$
Step-by-step explanation:
We are told that she starts with 50$
We are also that after 30 years she earns 110% on interest
Given this information we need to find the value of the bond after the 30 years
To do so we take 110% of the initial value (50$) and add that to the initial value
So the answer = 110%(50) + 50
110%*50=55
55+50=105
So in 30 years the bond will be worth 105$

There's no "supereasy" way to solve it, except by computation or approximation.
e.g. 2 3 6 couldn't work, because 2+3 < 6 so it's not even a triangle
125^2 cannot equal 122^2 + 30^2, because 125^2 is odd and 122^2 and 30^2 are even
23^2 + 18^2 = 529 + 324 < 900 < 31^2
So it has to be the last one, and after verification we find it checks out and 28^2 + 195^2 = 197^2

Answer:
x = 42.5
Step-by-step explanation:
A triangle formed inside of a circle using the diameter as one of its side lengths is a right triangle
The right angle would be the angle opposite of the diameter (∠C)
A right angle has a measure of 90°
That being said we use this equation to solve for x
90 = 2x + 5
step 1 subtract 5 from each side
90 - 5 = 85
5 - 5 cancels out
now we have 85 = 2x
step 2 divide each side by 2
85/2=42.5
2x/2=x
we're left with x = 42.5
