Answer:
x = 26
Step-by-step explanation:
6x + 6x + (x-2) + (x-2) = 360
14x - 4 = 360
14x = 364
x = 26
6(26) = 156
(26 - 2) = 24

Ambika borrowed Rs. 8000 from a bank at 8% per annum and kept it with her
for 3 years. How much amount should she pay to clear the debt after 3 years?
Hope it helps u mate........
Answer:
9920
Step-by-step explanation:
S.I=PTR/100
A=P+SI
so, we can say A=P+PTR/100
calculate it
Principal is given 8000
SI=8000×8×3/100=1920
A=8000+1920=9920
so amount 9920 should be payed after 3 year to clear her debt

y = -23x^2 + 1317x - 10749
Answer:
Step-by-step explanation:
y=-23x^2+1317x-10749
dy/dx=-64x+1317, d2y/d2x=-64, since d2y=-65, a global max occurs when dy/dx=0
-64x+1317=0, x=1317/64=20.578125
y(20.578125)=$6612.83

The Corresponding Angles Conjecture states that if two
parallel lines are cut by a transversal, the corresponding
angles are congruent. The picture below shows this
relationship
Answer:
B
Step-by-step explanation:
Corresponding angles form a sideways U when you connect the angles.
b is the only one that does that.
1 and 4 are consecutive angles.
1 and 3 are vertical angles
4 and 3 are linear pair angles.
Find the area and Perimeter of the shape made
by connecting the following
points in order.
P (0,5) V (2,8) H (5,8) (5,5)
Answer:
area = 12 units²
perimeter = 17.61 units
Step-by-step explanation:
line VP² length = 2² + 3²
line VP = 3.61 units
perimeter = 5+3+3+3.61 = 17.61 units
area = (3)(3) + (1/2)(2)(3) = 12 units²

The number is 5.
Step-by-step explanation:
Finding the Number
To find the number, we have to form the algebraic equation first by translating the given mathematical problem above to algebraic expression. The algebraic equation is a statement that shows the equality of two algebraic expressions.
Equation:
Let "x" be the number.
"four times the square of a number" = 4x²
"20 times that number" = 20x
"four times the square of a number equals 20 times that number"
4x² = 20x
Solution:
4x² = 20x
4x²/4x = 20x/4x
x = 5
Final Answer:
The number is 5.
Checking:
To check, substitute the number.
4x² = 20x
4(5²) = 20(5)

Find the area of this circle. Use 3 for pi.
Answer:
Area= 48 cm²
Step-by-step explanation:
Since the radius is 4, to get area, you must get 4 squared(4 x 4), which is 16. Then, multiply 16 to 3(pi), and the answer is 16 x 3 = 48.

PLZ ANSWER WILL GIVE 25 POINTS AND WILL MARK BRAINLIEST!! PLEASE I NEED ASAP
Answer:
7 quarters and 3 dimes
Step-by-step explanation:
x: quarter y: dime
25x + 10y = 205
x+y=10
y = 10-x
25x + 10*(10-x) = 205
25x+100 -10x = 205
15x = 105
x = 7
7 = 10-7 = 3

Lydia is an architect. She has to design a courtyard garden inside a new hotel. On her blueprint, which is 1/20 the size of the actual garden, the width of the garden is 36 inches. What is the width of the actual garden?
Answer:
720 inches
Step-by-step explanation:
On her blueprint, which is 1/20 the size of the actual garden
the width of the garden is 36 inches.
What is the width of the actual garden?
Let width of the actual garden = x
1/20 of x = 36
1/20 * x = 36
x = 36 ÷ 1/20
x = 36 * 20/1
x = 720
x = 720 inches
The width of the actual garden = 720 inches
shown is a regular pentagon, find y.
Answer:
Step-by-step explanation:
Each angle of regular pentagon = 108
Given triangle is an isosceles triangle
In this triangle,
y + y + 108 = 180 {angle sum property}
2y + 108 = 180
2y = 180 - 108
2y = 72
y = 72/2
y = 36
As we know that,
[tex]\star[/tex] Each angle of regular pentagon = 108°.
The triangle given to us is a Isosceles Triangle.
In the given triangle,
[tex]\longrightarrow\rm{y + y + 108 = 180 \: ... \: (Angle \: sum \: property)} \\ \\ \longrightarrow\rm{2y + 108 = 180} \\ \\ \longrightarrow\rm{2y = 180 - 108} \\ \\ \longrightarrow\rm{2y = 72} \\ \\ \longrightarrow\rm{y = \frac{\cancel{72}}{\cancel{2}}} \\ \\ \longrightarrow\rm{y = 36} \: \bigstar[/tex]Henceforth;
The value of y is 36.

Step-by-step explanation:
A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the maximum height reached by the rocket, to the nearest tenth of a foot.
y=−16x^2+
180x+63
Answer:
To find the maximum of a function in ax^2 + bx + c form, you can use the formula: maximum = c - (b^2 / 4a).
In this question, a = -16, b = 180, and c = 63.
Maximum = 63 - (180^2/4(-16))
Maximum = 569.25
Finally, rounding this to the nearest tenth of a foot, the final answer is 569.3 ft.
Let me know if this helps!
find the surface area of the triangular prism
Answer:
608 ft²
Step-by-step explanation:
1) Find the area of the bases
[tex]A=\frac{1}{2} bh[/tex] where b is the base length and h is the height
Plug in b and h
[tex]A=\frac{1}{2} (12)(8)\\A=48[/tex]
Multiply the answer by 2 (because there are 2 bases)
A=96
Therefore, the area of the two bases is 96 ft².
2) Find the area of the two sides facing up
[tex]A=lw[/tex] where l is the length and w is the width
Plug in l and w
[tex]A=10*16\\A=160[/tex]
Multiply the answer by 2 (because there are 2 sides)
A=320
Therefore, the area of these two sides is 320 ft².
3) Find the area of the bottom side
[tex]A=lw[/tex] where l is the length and w is the width
Plug in l and w
[tex]A=12*16\\A=192[/tex]
Therefore, the area of this side is 192 ft².
4) Add all the areas together
96 ft² + 320 ft² + 192 ft²
= 608 ft²
Therefore, the surface area of the triangular prism is 608 ft².
I hope this helps!
Answer:
608
Step-by-step explanation:
first off you have to find the area of the base
the base is 16 by 12 feet.
so you multiply them and you get
16*12=192 you will have to come back later for this number
next, you find the two outsides of the triangular prism.
they are 10 by 16
10*16=160 and there are two of them so you double it and get 320
now save the 320 too with the 192
now we are going to find the triangles
the formula for an area of a triangle is A=1/2h*w
so we plug in the height which is 8 and the width which is 12
A=1/2(8)*(12)
Simplify
A=48 once again there are two of them so we double it to make it 96
now take all your saved numbers and add them all up
96+320+192
this should give you an answer of 608
hope this helps! have a nice day:)
If cos(2/3(x) + 20) ° = sin(2x – 10)”, find the acute angles of the corresponding right triangle.
recall that
sin(x) = cos(90-x)
therefore
cos((2/3)x + 20) = cos(90 - [2x - 10])
(2/3)x + 20 = 100 - 2x
2x + (2/3)x = 80
divide through by 2
x + (1/3)x = 40
(4/3)x =40
4x = 40*3
4x = 120
x = 30
since it is a right angled triangle, the angles are 30, 60 and 90
Answer: A=40 B=50

Camden is deciding between two parking garages. Garage A charges an initial fee of
$12 to park plus $4 per hour. Garage B charges an initial fee of $8 to park plus $5 per
hour. Let A represent the amount Garage A would charge if Camden parks for t
hours, and let B represent the amount Garage B would charge if Camden parks for t
hours. Write an equation for each situation, in terms of t, and determine the hours
parked, t, that would make the cost of each garage the same.
Answer:
4 hours
Step-by-step explanation:
A = 12 + 4t
B = 8 + 5t
12 + 4t = 8 + 5t
t = 4
The cost of each garage would be the same when Camden parked the car for 4 hours
can someone please help with this. Thank you! :)

The cost of the circular carpet, $C, varies as the square of the radius,
r metres. If C = 200 when r= 2
Find the cost of the circular carpet when r= 3
Answer:
$450
Step-by-step explanation:
C = k[tex]r^{2}[/tex]
200 = k([tex]2^{2}[/tex]) = 4k
k = 50
C = 50[tex]r^{2}[/tex] = 50([tex]3^{2}[/tex]) = 50(9) = $450
What is X equal to in this problem?
Answer: X=80
Step-by-step explanation:
Know that all angles COMBINED in a triangle is 180, so we can use the two angles to setup the equation for the last one, since the total angle must be 180 then x added to those angles must add up to 180.so we get the equation x+59+41=180.x+100=180, subtract 100 from both sides to isolate x.x=80.
