PLEASE Find the value of x?
Answer:
Step-by-step explanation:
11 + 5 = big hipo = 16
16 / x = x / 5
x*x = 16*5
x² = 80
x = [tex]\sqrt{80}[/tex] (do this lame calculus)
x = 4[tex]\sqrt{5}[/tex]
y² = (4[tex]\sqrt{5}[/tex])² - 5²
y² = (4[tex]\sqrt{5}[/tex]) * (4[tex]\sqrt{5}[/tex]) - 25
y² = 16 + 4[tex]\sqrt{5}[/tex] + 4[tex]\sqrt{5}[/tex] + [tex]\sqrt{25}[/tex] - 25
y² = 16 + 8[tex]\sqrt{5}[/tex] + 5 - 25
y² = 16 + 8[tex]\sqrt{5}[/tex] - 20
y² = - 4 + 8[tex]\sqrt{5}[/tex]...

Graph a line representing the proportional relationship with slope 3 containing the point (2, 6).
To graph the line, plot two points on the line.
Answer:
(1, 3) and (0, 0)
Step-by-step explanation:
y = mx + b
m is the slope which is 3 (given)
b is the y intercept
(x, y) → (2, 6)
6 = 3(2) + b
6 = 6 + b
b = 0
so the equation is y = 3x
one point:
y = 3(1)
y = 3 when x = 1
(1, 3)
y = 3(0)
y = 0 when x = 0
(0, 0)

The soccer team played 7 games and scored the following number goals in each game: 2, 1, 3, 5, 3, 1, 4. What was the median number of goals the team scored for the seven games? goals
Answer:
3
Step-by-step explanation:
first put them in order
1 1 2 3 3 4 5
then cancel them down go from the front to the back so go like
1 then 5 then 1 again then 4 and etc
u would then end up with the last two numbers which is 3 and 3. if u had numbers like 5 and 7 u would have to find the number in the middle of which would be 6. in the case the two numbers you are left with is 3 and 3 since there both the same the answer would be 3

The wholesale price for a shirt is $7.50. A certain department store marks up the wholesale price by 80%. Find the price of the shirt in the
department store.
Round your answer to the nearest cent, as necessary.
Answer:
$13.50.
Step-by-step explanation:
80% = 0.80 as a decimal fraction.
The marked up price
= 7.50 + 0.80 * 7.50
= $13.50.
so the new price will just be 7.5 plus 80% of 7.5

5 1/8+ 2 1/3 = 7 1/2 -4 1/2+ 6 3/4= 2 1/4
Robert's 5 1/8 + 2 1/3 = 7 1/2 is wrong because if 5+2 = 7, I would have to change the denominator of both fractions so they are both the same.
What is the equation?A statement that the values of two mathematical expressions are equal.
The denominator would have to be 24.
That would make the fractions 3/24 and 8/24.
If you added them together, it would not be able to simplify to 1/2.
Casey is correct.
-4 1/2 + 6 3/4 = 2 1/4 is correct
because 4 - 6 = 2.
In order to make the fractions have the same denominator, you would have to multiply -1/2 by 2 on both numerator and denominator which would equal -2/4.
Now add -2/4 and 1/4 and you get 1/4.

At Goodies restaurant the quantity of large pizza sold is 200 at the unit price of $15. suppose the price elasticity of demand for pizza is $1.5, and you would to increase the quantity sold to 250,then the new price must be?
The new price of pizza when the quantity sold is increased to 250 is $12.45.
What is the new price of pizza?Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.
Price elasticity of demand = percentage change in quantity demanded / percentage change in price
Percentage change in quantity demanded = (250 / 200) - 1 = 25%
Percentage change in price = 25% / 1.5 = 16.67%
New price = (0.1667 x 15) - 15 = $12.45

So
We need base
cosA=Base/Hypotenusecos75=B/10B=10cos75B=2.58ftAnswer:
a) 67°
b) 2.6 ft
Step-by-step explanation:
Part (a)This problem can be modeled as a right triangle (see attachment 1), where the wall and the ground are the legs, and the ladder is the hypotenuse. Therefore, we can use the sine trig ratio to find the angle.
Trig Ratio
[tex]\sf \sin(\theta)=\dfrac{O}{H}[/tex]
where:
[tex]\theta[/tex] is the angleO is the side opposite the angleH is the hypotenuse (the side opposite the right angle)Given:
[tex]\theta[/tex] = xO = wall = 9.2H = ladder = 10Substituting the given values into the ratio and solving for x:
[tex]\implies \sf \sin(x)=\dfrac{9.2}{10}[/tex]
[tex]\implies \sf x=\sin^{-1}\left(\dfrac{9.2}{10}\right)[/tex]
[tex]\implies \sf x=67^{\circ}\:(nearest\:degree)[/tex]
Part (b)(see attachment 2)
Let y be the distance the foot of the ladder and the foot of the building
We can find y by using the cos trig ratio:
[tex]\sf \cos(\theta)=\dfrac{A}{H}[/tex]
where:
[tex]\theta[/tex] is the angleA is the side adjacent the angleH is the hypotenuse (the side opposite the right angle)Given:
[tex]\theta[/tex] = 75°A = grounds = yH = ladder = 10Substituting the given values into the ratio and solving for x:
[tex]\implies \sf \cos(75^{\circ})=\dfrac{y}{10}[/tex]

Five runners need to be arranged in 5 lanes for a race so that there is a runner in each lane. How many unique ways are there to arrange the runners in the 5 lanes?
Answer:
25
Step-by-step explanation:
When answer questions about unique combinations, there are usually two ways people go about finding the solutions.
First, sometimes it can take a while, but it often helps people visualize the question if they jot down or sketch each different combination. Then, they can just count them up at the end to find there answer.
The easeier way is to use a quick math trick. If you have 5 runners, with 5 potential lanes each runner could start in, you can just multiply these two variables together to get your answer of the number of possible options.
So,
5 runners * 5 lanes = 25 possible combinations for each lane and runner
The number of unique ways that the runner can be arranged in 5 lanes for a race is 120.
What are Combinations?Combinations are defined as the arrangement of objects or numbers in a way such that the order of the arrangement does not matter.
Total number of runners = 5
Total number of lanes = 5
Number of ways that 5 runners can be arranged = 5! = 120
Hence the number of ways is 120.

Answer:
Center: (-7, -4)
radius = 4
Explanation:
Equation: (x + 7)² + (y + 4)² = 16Circle formula:
(x - h)² + (y - k)² = r²(h, k) denotes the center of the circle, "r is radius"
Rewrite the following equation in standard form:
(x - (-7))² + (y - (-4))² = 4²From this identify:
h = -7, k = -4, radius = 4General equation
(x-h)²+(y-k)²=r²

(x+7)²+(y+4)²=16(x+7)²+(y+4)²=4²Center=(-7,-4)

Subtract 2x from both sides
46 = 5x - 9
Add 9 to both sides
55 = 5x
