Answer:
144
Step-by-step explanation:
use formula (n-2)(180), n is the number of sides (in this case it is 10)
(10-2)(180)
(8)(180)
1440
then divide by number of sides in polygon
1440/10 = 144

The circumference of a circular garden is 28 feet. Which of the following expressions best represents the radius of the garden?
A. 28π28 over pi
B. 28(π)28 times pi
C. 282π28 over 2 pi
D. 28(2π)
Answer: The answer is ACTUALLY C
Step-by-step explanation:
REMEMBER: The radius is always half of the diameter.
So the question is asking us what is the radius of a garden with a circumference of 28. In order to find HALF of that you would need to divide 28 so the answer is ( C ) not d...
SOLID PROOF:
y=-2х - 4 y=x - 5 how many solutions does this have
Answer:
one solution
Step-by-step explanation:
-2x - 4 = x - 5
-3x - 4 = -5
-3x = -1
x = 1/3
y = 1/3 - 5
y = 1/3 - 15/3
y = -14/3
(1/3, -14/3)

Elise is standing on top of a 50 foot building and sees her friend, Molly. If Molly is 30 feet away from the base of the building, what is the angle of depression from Elise to Molly? Elise's eye height is 4.5 feet.
Answer:
59.04°
Step-by-step explanation:
Elise is standing on top of a 50 foot building and sees her friend, Molly. If Molly is 30 feet away from the base of the building, what is the angle of depression from Elise to Molly? Elise's eye height is 4.5 feet.
We solve using the Trigonometric function of Tangent
tan x = Opposite/ Adjacent
tan x= 50 ft/30ft
x = arc tan (50 ft/30 ft)
x = 59.036243468°
Approximately = 59.04°

question: solve for the solution using substitution.
Answer:
Step-by-step explanation:
6(2x+ 10) = x - 61
12x + 60 = x - 61
11x + 60 = -61
11x = -121
x = -11
6y= -11 - 61
6y = -72
y = -12
(-11, -12)
y=2x+10
Swap sides so that all variable terms are on the left hand side.
2x+10=y
Subtract 10 from both sides.
2x=y−10
Divide both sides by 2.
2
2x
=
2
y−10
Dividing by 2 undoes the multiplication by 2.
x=
2
y−10
Divide y−10 by 2.
x=
2
y
−5
SOLVE FOR Y
y=2(x+5)
6y=x−61
Swap sides so that all variable terms are on the left hand side.
x−61=6y
Add 61 to both sides.
x=6y+61
SOLVE FOR Y
y=
6
x−61
plssss help thankyou
Answer:
2nd answer choice No, 6/2 does not equal 2/24 :)
Step-by-step explanation:
6/2=3 while 24/10=2.4
Another way you could think about it:
6*2=12
2+2=4
6*3=18
4+2=6
6*4=24
6+2=8
So 24 ounces of the shake would only be 8 grams of protein.

The next week Jackie worked, her gross pay was $650. If she has to pay a $10 uniform fee, 1.45% in Medicare, and 4.2% in FICA, what is her net pay after these deductions?
a.) $613.27
b.) $603.27
c.) $604
Answer:
1.45%+4.2%= 5.65%
100%->650
5.65%-> 36.725
650- 36.725 - 10 = 603.275
~ 603. 27
hence answer is b

what is the least common denominator of the equation 3/4(x-3)-1/2=2/3
Answer: 3(x-3)/4-1/2=2/3
Step-by-step explanation:
The least common denominator will be the least common multiple of 4,2,3 which is the product of the highest occurring primes of the numbers prime factorization...
4=2*2, 2=2, 3=3, so the least common denominator is 2*2*3=12

The diagram shows triangle PQR.
PSR is a straight line.
size of angle PQS : size of angle SQR = 3:1
S
Work out the size of angle PSQ
Answer:
Angle PSQ is 61°
Step-by-step explanation:
In the triangle ΔPQR, we have;
m∠QPS = 65°
m∠PRQ = 43°
Line PSR is a straight line
m∠PQS : m∠SQR = 3:1
Therefore;
∠PQR = 180° - (∠QPS + ∠PRQ), by the angle sum theorem of a triangle
∴ ∠PQR = 180° - (65° + 43°) = 72°
∠PQR = 72°
∠PQR = m∠PQS + m∠SQR by angle addition postulate
m∠PQS : m∠SQR = 3:1
∴ m∠PQS = 3 × m∠SQR
∴ ∠PQR = m∠PQS + m∠SQR = 3 × m∠SQR + m∠SQR = 4 × m∠SQR
∠PQR = 4 × m∠SQR
∴ 4 × m∠SQR = ∠PQR = 72°
m∠SQR = 72°/4 = 18°
m∠PQS = 3 × m∠SQR = 3 × 18° = 54°
m∠PQS = 54°
∠PSQ = 180° - (∠QPS + ∠PQS) by the angle sum theorem
∴ ∠PSQ = 180° - (65° + 54°) = 61°
Angle ∠PSQ = 61°.
