Factor the difference of squares.
x2 - 400
The factored form of x2 - 400 is
Answer:
The factored form of x²-400 is (x+20)(x-20).
Step-by-step explanation:
Given the expression
[tex]x^2\:-\:400[/tex]
As the square of 20 is 400. Therefore, rewrite 400 as 20²
⇒ [tex]x^2-20^2[/tex]
[tex]\mathrm{Apply\:Difference\:of\:Two\:Squares\:Formula:\:}x^2-y^2=\left(x+y\right)\left(x-y\right)[/tex]
Thus, the expression becomes
[tex]x^2-20^2=\left(x+20\right)\left(x-20\right)[/tex]
Thus, the factored form of x²-400 is (x+20)(x-20).
Another car dealership sells a truck for the wholesale price of $12,000. During a special sales event, the dealership offers a 10% discount off of the price. After the discount, how much will a customer pay for this vehicle? Show your work.
Answer:
$10,800
Step-by-step explanation:
Given that:
Wholesale price of the truck = $12,000
At the special sales event, the discount offered on the price = 10% of the wholesale price
Therefore the discount can be calculated as follows:
10% of Wholesale price
Wholesale price is given as $12,000.
[tex]\Rightarrow \dfrac{10}{100} \times 12000\\\Rightarrow \bold{\$1200}[/tex]
Now, we have to find the price to be paid by customer after the discount being offered due to the special sales event.
Discounted price = Wholesale price - Discounted offered due to special sales event.
Discounted price = $12000 - $1200 = $10,800
Therefore, the answer is:
$10,800

Carl is making accessories for the soccer team. He uses 666.96 inches of fabric on headbands for 39 players and 3 coaches. He also uses 333.06 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?
Answer:
The amount of fabric was used on :
a) headband for each player = 15.88 inches of fabric
b) wristband for each player = 8.54 inches of fabric
Step-by-step explanation:
From the above question, we were told:
For headbands
Carl is making accessories for the soccer team. He uses 666.96 inches of fabric on headbands for 39 players and 3 coaches.
Total number of persons = 39 players + 3 coaches = 42 persons
42 persons = 666.96 inches
1 person = x
Cross Y
42x = 666.96 inches
x = 666.96 inches/42
x = 15.88 inches
For wristbands
He also uses 333.06 inches of fabric on wristbands for just the players.
We have 39 players
Hence:
39 players = 333.06 inches
1 players = x
Cross Multiply
39x = 1 × 333.06 inches
x = 333.06 inches/3
x = 8.54 inches
The amount of fabric was used on :
a) headband for each player = 15.88 inches of fabric
b) wristband for each player = 8.54 inches of fabric
Question 8 (5 points)
(02.07 MC)
In the figure shown, what is the measure of angle x? (5 points)
150 degrees
110 degrees
105 degrees
100 degrees
Given:
Consider the below figure attached with this question.
To find:
The value of x.
Solution:
According to the exterior angle theorem, the exterior angle of a triangle is equal to the sum of two opposite interior angles.
In triangle ABC, using exterior angle theorem, we get
[tex]\angle ACD=\angle ABC+\angle BAC[/tex]
[tex]x=75^\circ +30^\circ [/tex]
[tex]x=105^\circ [/tex]
The value of x is 105 degrees.
Therefore, the correct option is C.

Write the equation of the line passing through the points (28,4) and (-4,-4).
Answer:
The general equation of a straight line is y = mx + c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis. The equation of a straight line with gradient m and intercept c on the y-axis is y = mx + c.

[tex]\huge\boxed{\sf \frac{-16}{147} }[/tex]
Step-by-step explanation:
Multiplicative Inverse of [tex]\sf 3\frac{1}{2} (\frac{7}{2} )[/tex] = [tex]\sf \frac{2}{7}[/tex]
Multiplicative inverse of any number is the reciprocal of that number.
Additive inverse of [tex]\sf 2\frac{5}{8}(\frac{21}{8} )[/tex] = [tex]\sf -\frac{21}{8}[/tex]
Additive Inverse of any number is the number that has the opposite sign.
Solution:
[tex]\sf \frac{2}{7} / - \frac{21}{8} \\\\\frac{2}{7} * - \frac{8}{21} \\\\= \frac{2*(-8)}{7*21} \\\\= \frac{-16}{147} \\\\\rule[225]{225}{2}[/tex]

Dasher wrapped 16 of the 54 presents for Christmas.
Please represent how many presents his contribution was as a fraction and as a percent.
9/27 and 30%
Step-by-step explanation:
16/ 54 then reduced to 9/27
to find percent divide 16/54 to get 0.296 then round that to 0.30 multiple by 100 to change to percent which is also just moving decimal over 2 places so 30%

What are the factors of -24 that have a sum of 5?
Answer:
Step-by-step explanation:
5 Easy as 1-2-3
5 is a prime number.
Prime factorization: 5 is prime.
The exponent of prime number 5 is 1. Adding 1 to that exponent we get (1 + 1) = 2. Therefore 5 has exactly 2 factors.
Factors of 5: 1, 5.
Factor pairs: 5 = 1 x 5.
5 has no square factors that allow its square root to be simplified. √5 ≈ 2.236.
