Answer:
x= 5 / 12
Step-by-step explanation:
Simplify both sides of the equation.
12x=5+5−5
12x=5+5+−5
12x=(5+5+−5) (Combine Like Terms)
12x=5
12x=5
Step 2: Divide both sides by 12.
12x / 12
x = 5 / 12
12x = 5 + 5 - 5
12x = 10 - 5
12x = 5

The equation of a circle is x 2 + y 2 + 6 y = 7 x 2 + y 2 + 6 y = 7 . What are the coordinates of the center and the length of the radius of the circle?
Answer:
Vertex: (0,-3)
Radius: 4
Step-by-step explanation:
Complete the square
[tex]x^2+y^2+6y=7\\\\x^2+y^2+6y+9=7+9\\\\x^2+(y+3)^2=16[/tex]
The equation of a circle takes the form of [tex](x-h)^2+(y-k)^2=r^2[/tex] where its center is [tex](h,k)[/tex] and its radius is [tex]r[/tex].
Hence, the vertex is [tex](0,-3)[/tex] and the radius is [tex]4[/tex].

Answer:
585 m^2.
Step-by-step explanation:
Surface area = area of base + 4 * area of a triangular side
= 13^2 + 4 * 1/2 * 13 * 16
= 169 + 26 * 16
= 585
Answer:
585 m²
Step-by-step explanation:
The surface area of the given pyramid is made up of 4 congruent triangles and a square base.
Area of a triangle = 1/2 × base × height
= 1/2 × 13 × 16
= 104 m²
Area of a square = (base edge)²
= 13²
= 169 m²
Total Surface Area = area of 4 triangles + area of base square
= (4 × 104) + 169
= 416 + 169
= 585 m²

Y=-2X, Y=5X+3 how do I solve this equation using substitution or elimination
Answer:
y= -2x........eqn i
y=5x+3......eqn ii
substituting the value of Y from eqn i in eqn ii, we get,
-2x=5x+3
-7x=3
x= -3/7
so, y= -2x= -2× (-3/7)
so, y= 6/7

A triangle has sides with lengths of 10 millimeters, 25 millimeters, and 28 millimeters, is it a right triangle
Answer:
No, it is not a right triangle.
Step-by-step explanation:
Let's take it as,
→ Hypotenuse = 28 mm
→ Perpendicular = 25 mm
→ Base = 10 mm
Now use Pythagoras theorem,
→ Hypotenuse² = Perpendicular² + Base²
→ 28² = 25² + 10²
→ 784 = 625 + 100
→ 784 ≠ 725
→ [ LHS ≠ RHS ]
Hence, it does not forms a right triangle.
A function and its inverse are shown on the graph. Which statement describes the relationship between the function and its inverse? The range of both f(x) and f–1(x) is all real numbers. The domain of both f(x) and f–1(x) is all real numbers. The range of f(x) is y > 0 and the domain of f–1(x) is x > 0. The domain of f(x) is x > 0 and the range of f–1(x) is y > 0.
Answer:
Option (C)
Step-by-step explanation:
Domain of function is defined by the set of x-values (input values) and Range of a function is a set of y-values (output values).
From the graph attached,
Domain of f(x) → Set of all real numbers
Range of f(x) → y-values > 0
Domain of [tex]y > 0[/tex] → Set of all real numbers
Range of [tex]y > 0[/tex] → y < 2
Therefore, domain of both the functions is a set of all real numbers.

What is Area of Trapezium?The area of a trapezium can be calculated using the lengths of two of its parallel sides and the distance (height) between them.
As the yard is in shape of Trapezium.
We have to find the area of trapezium.
Area of piece of property = Area of Triangle + Area of rectangle + Area of Triangle
Area of Triangle I,
base = [tex]\sqrt{(13)^{2}{-(12)^{2}}[/tex] = [tex]\sqrt{169-144}[/tex]= 5yds
Area = [tex]\frac{1}{2}*b*h[/tex]
=0.5 x 5 x 12
= 30 squared yds
Area of rectangle = length x breadth
= 10 x 12
= 120 squared yds
Area if Triangle II, base = [tex]\sqrt{(15)^{2}{-(7)^{2}}[/tex]= [tex]\sqrt{225-49}[/tex]= [tex]4\sqrt{11}[/tex]
Area= [tex]\frac{1}{2}*b*h[/tex]
=0.5 x [tex]4\sqrt{11}[/tex] x 12
= [tex]24\sqrt{11}[/tex] squared yds
Area of piece of land = 30 + 120 + [tex]24\sqrt{11}[/tex]
= 150 +[tex]24\sqrt{11}[/tex] squared yards
Hence, the area of piece of land= 150 +[tex]24\sqrt{11}[/tex] squared yards

31 Answer:
Solve: 0.75% of 93 = n n = _____
Step-by-step explanation:
13.
132 miles in 3 h = 132miles/3hours = 132/3 miles/h =
= 44 miles/h
so,
how long for 110 miles ?
speed = distance/time
time = distance/speed = 110 miles / 44 miles/h =
= 110/44 h = 55/22 h =
= 5/2 h = 2.5 h
14.
60% = 60/100 = 6/10 = 3/5
15.
300% = 300/100 = 3
16.
116 2/3% = (348 + 2)/3% = 350/3% = 350/3/100 =
= 350/300 = 1 50/300 = 1 1/6
17.
19% = 19/100
18.
3.8% = 3.8/100 = 38/1000 = 19/500
19.
166 2/3% = (498 + 2)/3% = 500/3% = 500/3/100 =
= 500/300 = 5/3 = 1 2/3
20.
4/5 = 0.8 = 80%
21.
7/4 = 1.75 = 175%
22.
1/3 = 0.3333333... ≈ 33.33%
23.
2 = 200/100 = 200%
24.
0.4 = 40%
25.
0.375 = 37.5/100 = 37.5%
26.
80% of 60 = 60×80/100 = 60×4/5 = 48
27.
24% of 65 = 65×24/100 = 65×6/25 = 13×6/5 =

115% of 138 = 138×115/100 = 138×23/20 =

18.3% of 74 = 74×18.3/100 = 74×183/1000 =

What is the surface area, in square inches, of the square pyramid?
Answer:
261 in²
Step-by-step explanation:
The surface area of a square pyramid can be found from the formula ...
A = s(s +2h)
where s is the side length of the base and h is the slant height of a face.
__
For s = 9 in, and h = 10 in, the surface area is ...
A = (9 in)(9 in +2×10 in) = (9·29) in² = 261 in²
The surface area of the square pyramid is 261 square inches.
Pema is 85 months old and Rinzin is 7⅔ years old. who is older? How do you know?
help me slove this please
Answer:
Rinzin is older
Step-by-step explanation:
The reason is that since you probably already know that there are 12 months in a year it would be 85/12=7.0833 years and 23/12=7.666 so that makes rinzin older
Hope that helps :)
Pema is older than Rinzin if Pema is 85 months old and Rinzin is 7⅔ years old.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Pema is 85 months old and
Rinzin is 7⅔ years old.
We have to check who is older.
We know that 1 year = 12 months
So if 85 months are conveted to years by dividing 85 by 12
Pema, 85/12 years= 7.08 years
Rinzin, 7⅔ years = 7.06 years
We know that 7.08>7.06
Hence, Pema is older than Rinzin if Pema is 85 months old and Rinzin is 7⅔ years old.

If you deposit $25,000 now at 6.5% compounded quarterly, how much will you have in 30 years?
Answer:
$172,984.44
Step-by-step explanation:
We can use the formula
[tex]A = P(1 + \frac{r}{n})^{nt}[/tex] to compute the final amount
Here P is the principal amount, the original deposit = $25,000
r is the annual interest rate = 6.5% = 0.065 in decimal
n is the number of times the compounding takes place. Here it is quarterly so it is 4 times a year
t is the number of time periods ie 30 years
A is the accrued amount ie principal + interest
Computing different components,
[tex]nt = 4 \times 30 = 120[/tex]
[tex]r/n = 0.065/4 = .01625[/tex]
[tex]1 + r/n = 1.01625[/tex]
[tex](1 + r/n)^{nt} = 1.01625^{120}[/tex]
Therefore
[tex]A = 25000 \times 1.0625^{120} = 172,984.44[/tex]

What is the slope of the line?
m=
Answer:
The slope is [tex]-\frac{4}{3}[/tex]
Step-by-step explanation:
Standard form for a linear equation/graph:
[tex]y = mx + b[/tex]
[tex]m[/tex] is the slope, and [tex]b\\[/tex] is the Y- intercept (basically where the graph crosses the y axis).
[tex]m[/tex] can be shown by a fraction: [tex]\frac{Rise}{Run}[/tex]
In this graph, measuring from the two points of contact, the rise is 4 and the run is -3. If the graph moves towards the left while rising, then the run part of the slope should be negative, and vice versa.
Thus, the slope of this graph is [tex]-\frac{4}{3}[/tex]
Here's the function for the line if you need it:
[tex]y = - \frac{4}{3} x + 3[/tex]
