Find the value of r.
Note: Write your answer as a decimal.
Answers
Answer:
[tex]\huge\boxed{\sf r = 10.5}[/tex]
Step-by-step explanation:
Since it is a right-angled triangle, it has base, perpendicular and hypotenuse.
Base = r
Perpendicular = 14
Hypotenuse = r + 7
Using Pythagoras theorem:
[tex](Hypotenuse)^2 = (Base)^2+(Perp)^2[/tex]
Put the values
(r + 7)² = (r)² + (14)²
Using formula a² + 2ab + b² = (a + b)²
r² + 14r + 49 = r² + 196
Subtract r² to both sides
14r + 49 = 196
Subtract 49 to both sides
14r = 196 - 49
14r = 147
Divide 14 to both sides
r = 147 / 14
r = 10.5

You earn $1,166 gross taxable income every week, and have claimed no exemptions. assuming that you have no other sources of income, what is the amount of income tax withheld each week? for weekly gross income between 1,160 and 1,170 dollars and claiming no exemptions, 340 dollars will be withheld each week. a. $323 b. $337 c. $340 d. $344
Answers
They are exempt from income tax and we would get the income tax withheld as $340
What is income tax?Income tax is a tax applied on individuals or entities concerning income or profit earned by them.
You earn $1,166 gross taxable income every week and have claimed no exemptions. assuming that you have no other sources of income.
Gross taxable Income = $ 1,166
Rate of Income tax = 30%
Amount of income tax = 30 % of 1,166
= 30/100 × 1,166
= $339.6
= $340
Therefore. they are exempt from income tax and we would get the income tax withheld as $340.

Sasha’s daily tips this work week were $43, $32, $65, $88, $50, and $72. Is Sasha correct in thinking that the mean accurately represents how much money she makes in daily tips? Yes, Sasha is correct. The mean amount she makes is $58. 33 in a day. Yes, Sasha is correct. The mean amount she makes is $65. 33 in a day. No, Sasha is not correct. The median amount she makes is $53. 00 in a day. No, Sasha is not correct. The median amount she makes is $60. 00 in a day.
Answers
Answer: Yes Sasha is correct she makes $58.33 a day
Step-by-step explanation: First add all the tips

Answers
363
Step-by-step explanationT1= a= -92
T2= -85
common difference d = T2-T1
d = -85 -(-92)
= -85 +92

Tn = a + (n-1)d
T66 = -92 + (66-1)7
= -92 + (65)7
= -92 + 455

If \cos\theta = \frac{2}{\sqrt{14}}cosθ= 14 2 and angle \thetaθ is in Quadrant I, what is the exact value of \tan 2\thetatan2θ in simplest radical form?
Answers
θ is in quadrant I, so cos(θ) and sin(θ) and hence tan(θ) are all positive.
Recall that
sec²(θ) = 1 + tan²(θ)
We have
cos(θ) = 2/√14 ⇒ sec(θ) = √14/2 = √(7/2)
Then
tan(θ) = +√(sec²(θ) - 1) = √(5/2)
Also recall the identities
sin(x + y) = sin(x) cos(y) + cos(x) sin(y)
cos(x + y) = cos(x) cos(y) - sin(x) sin(y)
from which we get
tan(x + y) = (sin(x) cos(y) + cos(x) sin(y)) / (cos(x) cos(y) - sin(x) sin(y))
tan(x + y) = (tan(x) + tan(y)) / (1 - tan(x) tan(y))
so that
tan(2θ) = 2 tan(θ) / (1 - tan²(θ)) = -(2√10)/3
Which sum is rational?
A. 1 + 18
B. 25 + 1.75
C. V3 + 5.5
D. I+V2
Answers
Answer: B. √25 + 1.75.
Step-by-step explanation: Rational Numbers are numbers that terminate or don't need to be terminated. For example, 1/3 is a repeating number, but we can terminate the value, whereas pi is never ending, and there is no terminating with that value. Numbers like 5.56 and 7/8 are rational because they don't need to be terminated to be rational. √25 is 5, no decimals to terminate or anything, and that makes the value rational. 1.75 is also rational, and that's why equation c is fully rational. √3 and √2 can't terminate, because both are 1.73205080757 and 1.41421356237, which means that they still can't terminate. Pi cannot terminate, so that's why the answer choices with pi aren't rational.

y = 4x + 7
X-intercept: ( __ , __ )
Y-intercept: ( __ , __ )
Answers
Answer:
y intercept is (0,7) & x is (7/4,0)
Step-by-step explanation:
you put 0 for y or x and solve to get the intercept. for y int, you put 0 where the x is. for x int, put 0 at y.
y intercept is (0,7).
y = 4(0) + 7
y = 0 + 7
y = 7
x intercept is (7/4,0)
0 = 4x + 7
7 = 4x
7/4 = 4x/4
7/4 = x

Find the area and circumference of the circle if It is 13 in
Answers
Answer:
Area: 531 in²
Circumference: 82 in
Step-by-step explanation:
Given:
radius = 13 inchesπ = 3.14round to nearest whole numberTo find:
AreaCircumferenceArea of Circle:
[tex]\displaystyle \large{A=\pi r^2}[/tex]
A = areaTherefore:
[tex]\displaystyle \large{A=3.14 \cdot 13^2}\\\displaystyle \large{A=530.66 }[/tex]
Round to nearest whole number:
If the digit is at least or greater than 5, round to 1.If the digit is less than 5, don’t do anything.Therefore, the area is 531 inches squared
Circumference of Circle:
[tex]\displaystyle \large{C=2\pi r}[/tex]
C = circumferenceTherefore:
[tex]\displaystyle \large{C=2\cdot 3.14 \cdot 13}\\\displaystyle \large{C=81.64}[/tex]
Round to nearest whole number:
Hence, the circumference is 82 inches
