Answer:
25/4 or 6.25
Step-by-step explanation:
Given that the general equation of a quadratic equation is given as
ax^2 + bx + c = 0, to complete the square, we subtract c from both sides of the equation and add the square of (b/2a) to both sides.
Hence given x^2-5x-19=0, to complete the square, we add
(-5/2)^2 to both sides following the illustration given.
This is 25/4 or 6.24

A store sells memory cards for $25 each.
The markup for each memory card is 25%. How much did the store pay for 50 memory cards?
Answer:
$937.50
Step-by-step explanation:
25 decrease 25% =
25 × (1 - 25%) = 25 × (1 - 0.25) = 18.75
18.75 × 50 = 937.50
The amount that the store pays for 50 memory cards will be $1,000.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
A store sells memory cards for $25 each. Then the cost price of each memory card is given as,
⇒ $25 / 1.25
⇒ $20
The amount that the store pays for 50 memory cards will be given as,
⇒ $20 x 50
⇒ $1,000
The amount that the store pays for 50 memory cards will be $1,000.

Answer:
8/3 meters (I wrote it as an improper fraction to avoid the hassle of writing repeating decimals)
Step-by-step explanation:
Don't try to include the timber in this problem. It is unnecessary. So, let's focus on the fact that the triangle with 3cm, 1.6m, and a portion of the timber is similar to the triangle with (3+2) cm, ?m, and the full length of the timber. Now, to find the ratio; we know that the side with 3 cm is similar to the side in the other triangle with a measure of 3+2=5 cm. So the ratio is 5/3. Now, we want to find out how far up the timber will go up the wall. This means you want to find the vertical measurement. So, multiply 1.6 (8/5) by 5/3, equaling 8/3.
Henry places £6000 in an account which pays 4.6% compound interest each year
Calculate the amount in his amount after 2 years
Answer:
£ 6,564.70
Step-by-step explanation:
Henry places £6000 in an account which pays 4.6% compound interest each year. Calculate the amount in his amount after 2 years
Compound Interest formula =
A = P(1 + r/n)^nt
A = Final Amounrt
P = Principal = £6,000
r = Interest rate = 4.6%
t = Time in years = 2 years
n = Compounding frequency = Yearly = 1
First, convert R percent to r a decimal
r = R/100
r = 4.6%/100
r = 0.046 per year,
Then, solve our equation for A
A = P(1 + r/n)^nt
A = 6,000.00(1 + 0.046/1)^(1×2)
A = £ 6,564.70
The amount in his account after 2 years = £ 6,564.70

In the laundry basket there are 4 black socks, 7 pink socks, and 10 white socks. Allison will randomly select 2 socks from the basket one at a time without replacement. What is the probability that Allison will select 2 pink socks?
Answer: [tex]\dfrac{1}{10}[/tex]
Step-by-step explanation:
Given: In basket, we have
4 black socks, 7 pink socks, and 10 white socks.
Total socks = 4+7+10 = 21
Probability that first sock is pink = [tex]\dfrac{\text{Number of pinks socks}}{\text{Total}}=\dfrac{7}{21}=\dfrac13[/tex]
Now basket has 6 pink socks left and total socks left= 20
Probability that second sock is pink =[tex]\dfrac{6}{20}=\dfrac{3}{10}[/tex]
The probability that Allison will select 2 pink socks = [tex]\dfrac13\times\dfrac{3}{10}=\dfrac{1}{10}[/tex]
Hence, the probability that Allison will select 2 pink socks = [tex]\dfrac{1}{10}[/tex]

A gift store owner used 9 rolls of wrapping paper to wrap his customers’ gifts last week. Each roll was 66 1/2 in. long. How many gifts did he wrap if a 9 1/2 in. long piece of wrapping paper was used to wrap each gift?
Answer:
Answer is 7
Step-by-step explanation:
If the roll was 66 1/2 rolls long, we have to calculate and know how many pieces of wrapping paper for the roll so if each wrapping paper is 9 1/2 then you would have to divide 66 1/2 by 9 1/2 so you would need 7 wrapping papers.

TUJ = 29
Step-by-step explanation:
178-149
Answer:
m∠ TUJ = 29°
Step-by-step explanation:
Although this question looks hard, it really is not.
Since we know that TUV = 178° and we know that JUV = 149° we can easily figure out TUJ.
First, since we know that the total is 178° (TUV) we can subtract angle JUV from TUV to get TUJ
178° - 149° = ?
178° - 149° = 29°

Write an equation in slope intercept form (y=max+b) for the line passing through the points. Show your algebraic solving steps.
(-2, -1) and (2,3)
Find the gradient first
m = (y2-y1)/(x2-x1) = 3-(-1)/2 - (-2) = 4/4 = 1
then find the equation of the... slope ._.
y - y1 = m(x - x1)
y - (-2) = 1(x - 3)
y + 2 = x - 3
y =x -3 - 2
y = x - 5
So the equation is y = x - 5
