Answer:
x = sqrt(147)
Step-by-step explanation:
This is a right triangle, so we can use the Pythagorean theorem.
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse.
x^2 +7^2 = 14^2
x^2 +49 = 196
Subtract 49 from each side
x^2 = 147
Take the square root of each side
sqrt(x^2) = sqrt(147)
x = sqrt(147)
Answer:
[tex]7\sqrt{3}[/tex] or 12.12
Step-by-step explanation:
The pythagorean theorem states that a^2 + b^2 = c^2, with a and b representing the legs and c representing the hypotenuse.
7^2 + x^2 = 14^2
49 + x^2 = 196
x^2 = 147
x = [tex]7\sqrt{3}[/tex] or 12.12

Can someone answer my question please
Answer:
Step-by-step explanation:
Arc length=∅/360×2πr (can't find the symbol of theta, use ∅ instead LOL)
[tex]\frac{\theta }{360}\cdot 2\pi \left(11\right)=16[/tex]
[tex]\frac{\theta }{360}=\frac{16}{22\pi }[/tex]
[tex]\theta \:=\frac{16}{22\pi \:}\cdot 360[/tex]
[tex]{\theta}=83.34[/tex]
Answer:
≈ 1.5 radians
Step-by-step explanation:
The arc length is calculated as
arc = circumference of circle × fraction of circle
Here arc = 16 , then
2πr × [tex]\frac{0}{2\pi }[/tex] = 16 ← cancel the 2π on numerator/denominator
11 ×θ = 16 ( divide both sides by 11 )
θ ≈ 1.5 radians ( to the nearest tenth )

in order to get an A Mark needs to get at least 90% of the 650 points possible in the class. How many points must he earn of the 150-point final if he averaged 92 points on each of the five 100-point test
Answer:
at least 125 points on the final
Step-by-step explanation:
90% of 650 = 585
He needs at least 585 points to get at least 90%
Since he averaged 92 on the first 5 tests, he already has 5(92) = 460 pts
That means he needs to get at least 585 - 460 = 125 pts on the final exam

A company sells widgets. The amount of profit, y, made by the company, is related to
the selling price of each widget, x, by the given equation. Using this equation, find out
the maximum amount of profit the company can make, to the nearest dollar.
y= -2x^2 + 105x – 859
Answer:
519
Step-by-step explanation:
or 519.125
The maximum amount of profit the company can make, to the nearest dollar should be considered as the $519.
Calculation of the maximum amount of profitSince the amount of profit made expressed as [tex]y=-2x^2+105x-859[/tex]
Now
At maximum profit, dy/dx = 0
So,
dy/dx = -4x + 105
0 = -4x + 105
4x = 105
x = 105/4
x = 26.25
Now
[tex]y=-2x^2+105x-859\\\\y=-2(26.25)^2+105(26.25)-859[/tex]
y = - 1,378.125+2,756.25-859
y = 519.125
Hence the maximum amount of profit the company can make is $519.

A line that passes through the points whose coordinates are (1,1) and (5,7)
is dilated by scale factor of 3 and centered at the origin. The image of the line
a) is perpendicular to the original line
b) is parallel to the original line
c) passes through the origin
d) is the same line
Answer:
B
Step-by-step explanation:
The image that the line will produce would be:
b). is parallel to the original line.
Given that,
Coordinates = [tex](1,1) and (5,7)[/tex]
Scale factor [tex]= 3[/tex]
As we know,
Slope [tex]= \frac{y_{2} - y_{1} }{{x_{2} - x_{1}} }[/tex]
where;
[tex]y_{2} = 7[/tex]
[tex]y_{1} = 1[/tex]
[tex]x_{2} = 5[/tex]
[tex]x_{1} = 1[/tex]
By putting these values,
Slope [tex]= (7 - 1)/(5-1)[/tex]
[tex]= 6/4[/tex]
[tex]=[/tex] [tex]1.5[/tex]
∵The image of the line would be ║ to the original line.
Thus, option b is the correct answer.

5(x-4)+2x=14 help me find the answer x=?
Answer:
x = - 6/7
Step-by-step explanation:
Distribute 5 (x - 4) first --> 5x - 20
Combine like-terms: 5x - 20 + 2x = 14 --> 7x - 20 = 14
Subtract 20 on both sides: 7x = -6
Divide both sides by 7: x = -6/7

If the scale factor is 5/3 what is the width of the new rectangle?
Answer:
If 24 is the width then the answer is 40 and if 30 is the width then the answer is 50
Step-by-step explanation:
We multiply both sides by the scale factor to find both sides of the new rectangle. 30 * 5/3 = 50 and 24 * 5/3 = 40, so the sides of the new rectangle are 50 and 40. It matters whether 24 or 30 are the length or width, but if 24 is the width then the answer is 40 and if 30 is the width then the answer is 50

Daniel buys 17 raffle tickets.
A total of 280 tickets were sold
What’s the probability that Daniel does not win the prize
Answer:
263 / 280
Step-by-step explanation:
Given that :
Number of tickets bought = required outcome = 17
Total number of raffle = total possible outcomes = 280
Probability = required outcome / Total possible outcomes
P(winning) = 17 / 280
P(not winning) = 1 - 17/ 280
= 263 / 280
