Answer: x=500
Step-by-step explanation:
Twenty more (+20) of a fifth of a number (.2x) is equal to 120. So, the equation would be .2x+20=120. To isolate x, subtract 20 from each side. So now we have .2x=100. To get rid of the .2 or 1/5, we have to multiply everything by the reciprocal of 1/5, or 5. So, 100(5)=.2x(5), or simplified, x=500. Hope this helps!

Identify the 31st term of an arithmetic sequence where a1 = 26 and a22 = −226.
−334
−274
−284
−346
Answer:
a31 = -334
Step-by-step explanation:
Given:
a1 = 26
a22 = -226
Find:
a31
Computation:
a22 = a + 21d
-226 = 26 + 21d
d = -12
a31 = a + 30d
a31 = 26 + 30(-12)
a31 = 26 - 360
a31 = -334
a1 = 26 and a22 = −226.
Answer:
A) −334
A circle is centered at (0,0) and has a radius of 2\sqrt{3}
Where does the point M(−3,2) lie?
Answer:
Outside of the circle
Step-by-step explanation:
First, find the equation of the circle by plugging in the center point and radius:
(x - h)² + (y - k)² = r²
(x - 0)² + (y - 0)² = ([tex]2\sqrt{3}[/tex])²
x² + y² = 12
Plug in point M to see where it lies:
x² + y² = 12
(-3)² + (2)² = 12
9 + 4 = 12
13 ≠ 12
Since this statement is false, point M lies outside of the circle.
Can someone actually help me with this
Answer: X = 30*
All circles = 360*
we can subtract 260 from that because we know the length of one so we know the other is 130.
We are then left with only 100 and we know the two sides are equivalent so 100 / 2 = 50

Troy drew the diagram below. The inner circle has a radius of 2 units, and the outer circle has a radius of 5 units. Troy says the two circles are similar.
Which statement best explains whether Troy is correct, and why?
He is correct because the inner circle is a dilation of the outer circle.
O
He is correct because the inner circle has the same center as the outer circle.
O
He is not correct because the inner circle's radius is less than the outer circle's radius.
He is not correct because the inner circle's radius is not half of the outer circle's radius.
o
Answer:A he is correct because the inner circle is a dilation of the outer circle
Step-by-step explanation: just did the test
The statement "He is correct because the inner circle is a dilation of the outer circle" is the best explanation.
What is dilation?Dilation is the process of modifying the size of an item or form by reducing or expanding its dimensions according to specific scaling variables.
The radius of the inner circle is 2 units, while the radius of the outer circle is 5 units.
Since dilations provide similar figures because multiplying by the scale factor yields proportionate sides while keeping the angle measure and form constant.
Troy is accurate if he claims the two circles are similar.
Hence, the statement (A) "He is correct because the inner circle is a dilation of the outer circle" is the best explanation.

Answer:
(n + 1) (5m + 4)
Step-by-step explanation:
⇒ (n + 1) (5m + 4)
⇒ 5mn + 4n + 5m + 4
⇒ 5mn + 5m + 4n + 4
Answer:
(n + 1)(5m + 4)
Step-by-step explanation:
Given
5mn + 5m + 4n + 4 ( factor the first/second terms and the third/fourth terms )
= 5m(n + 1) + 4(n + 1) ← factor out (n + 1) from each term
= (n + 1)(5m + 4)

ITS SO CONFUSINGNSKDN
Answer:
y=67.7 Degrees
Step-by-step explanation:
You're given the opposite and adjacent sides to angle Y, so we use Tan to find the angle:
Tan(y)= 100/41
We then inverse tan to isolate y
y=tan^-1 100/41
y=67.7 Degrees
Note: Use a calculate to find the final answer
Which of these strategies would eliminate a variable in
the system of equations?
8x + 8y = 2
8x + 5y = 1
Answer:x = -1 / 12
Step-by-step explanation: am i right??
8x + 8y = 2 -------(1)
8x + 5y = 1 -------(2)
subtract equation (2) from equation (1)
The 8x will be eliminated, leaving us with;
3y = 1
Divide bothside of the equation by 3
y = 1/3
substituting y = 1/3 in equation (1)
8x + 8y = 2
8x + 8(1/3) = 2
8x + 8/3 = 2
subtract 8/3 from both-side
8x + 8/3 -8/3 = 2 -8/3
8x = 2 - 8/3
8x = 6 - 8 / 3
8x = - 2/3
Divide both-side of the equation by 8
8x / 8 = -2/3 ÷ 8
x = -2/3 × 1/8
x = -1 / 12

Answer: The walking path around it.
Step-by-step explanation:
Remember the Pythagorean's theorem, for a triangle rectangle with catheti A and B, and with hypotenuse H, we have:
A^2 + B^2 = H^2
or
H = √(A^2 + B^2)
Here, A + B is the total distance for the path, while the hypotenuse is the distance for the bridge
Here we can see that:
A = 1170 ft
B = 520 ft
Then:
H = √( (520 ft)^2 + (1170 ft)^2) = 1280.4 ft
Now, let's compute the costs.
For the bridge, we know that each foot costs $11, then for 1280.4 ft the cost is:
Cost of the bridge = (1280.4)*$11 = $14,084.4
And for the walking path, the cost is $6 per foot, then the total cost of the path is:
Cost of the path = (520 ft + 1170 ft)*$6 = $10,140
We know that the bridge is preferred if it is within the range of $1500 for the path's cost.
This range is:
($10,140 - $1,500, $10,140 + $1,500) = ($8,640, $11,640)
Here we can see that the cost of the bridge does not belong to this range, (is higher) so the option we should recommend is the walking path around.
