Answer:
(7√3)/3
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relation between sides of a right triangle and angles.
Tan = Opposite/Adjacent
That means ...
tan(30°) = x/7
Multiplying by 7, we have ...
x = 7·tan(30°)
x = (7√3)/3
Multiply(-7)(2)(-2)

Answer:
[tex]\frac{7x}{8}-\frac{1}{40}[/tex]
Step-by-step explanation:
[tex](\frac{3x}{4}-\frac{5}{8})+(\frac{x}{8}+\frac{3}{5})[/tex]
By combining the like terms,
= [tex](\frac{3x}{4}+\frac{x}{8})+(\frac{3}{5}-\frac{5}{8})[/tex]
= [tex](\frac{6x}{8}+\frac{x}{8})+(\frac{3}{5}\times \frac{8}{8}-\frac{5}{8}\times \frac{5}{5} )[/tex]
= [tex]\frac{7x}{8}+(\frac{24}{40}-\frac{25}{40})[/tex]
= [tex]\frac{7x}{8}-\frac{1}{40}[/tex]
Therefore, by solving the given expression we find the answer as [tex]\frac{7x}{8}-\frac{1}{40}[/tex].

area of rectangle = l*b
= (3x-y+4) ( X+7)
= 3x²-xy + 4x+21x-7y+28
= 3x²-xy +25x-7y +28
Area of square = l²
= (x-2)²= x²- 4x +4
area of shaded region=( 3x²-xy +25x-7y +28) -(x²- 4x +4)
=2x²-xy +29x-7y+24

23, 25, and 26
Please will make brainiest
If transversal t cuts parallel lines r and s, then the angles ∠3, ∠5 and ∠6 are congruent to ∠2.
What is Coordinate System?Coordinate systems are used to describe the (linear) position of points and the angular position of axes, planes, and rigid bodies.
A transversal is a line, ray, or line segment that intersects other lines, rays, or line segments on a plane at different intersecting points.
Congruent angles are two or more angles that are identical to each other.
The angle ∠2 measure is equal to ∠3.
∠2 measure is equal to ∠6.
∠6 measure is equal to ∠5.
The measures ∠3, ∠5 and ∠6 are equal to the measure of ∠2.
∠3, ∠5 and ∠6 are congruent to ∠2
Hence, if transversal t cuts parallel lines r and s, then the angles ∠3, ∠5 and ∠6 are congruent to ∠2.

the sum of rs 2400 compounded to rs 2646 in 2 years find the rate of interest
Answer:
principal (p) = 2400
Amount (A) =2646
time (t) = 2 years
Interest = A-p
=2646-2400=246
T = I * 100/(P*T)
= 246*100/(2400 *2) = 5.125%
Step-by-step explanation:
The rate of interest will be 5.125% for the given data.
What is compound interest?Compound interest, also known as interest on principal and interest, is the practice of adding interest to the principal amount of a loan or deposit.
Given that the sum of rs 2400 compounded to rs 2646 in 2 years. The compound interest will be calculated as,
principal (p) = 2400
Amount (A) =2646
time (t) = 2 years
Interest = A-p
=2646-2400=246
T = I x 100/(P x T)
T = ( 246 x 100) / (2400 x 2)
T = 5.125%
Hence, the interest rate will be %5.125.

An auto shop has 2 used vehicles for sale, 1 car and 1 truck. The truck is 3 years older than the car but 7 years older than one-half the car’s age. How many years old is the car?
Answer:
The car is 13 years old
Step-by-step explanation:
Lets say Car is x and the Truck is y, so the trucks age = x + 3 = y
Lets find the value of the Car or x
x + 3 = 1/2(x + 7)------- >
first we will divide x by 1/2 and 7 by 1/2, So...
x + 3 = (x / 1/2 + 7 / 1/2)------- >
x + 3 = 1/2x + 3.5------->
next Isolate variable x,
x + 1/2x = 3 + 3.5
1/2x = 6.5, So...
x = 13 and in turn, y = 13 + 3

5) x^2 +y^2 -8x -16y +54 = 0
6) x^2 +y^2 -10x -12y +36 = 0
Step-by-step explanation:
2) The standard form equation for a circle is ...
(x -h)^2 +(y -k)^2 = r^2
You are given the center: (h, k) = (3, -2) and a point on the circle. So, the equation will be ...
(x -3)^2 +(y +2)^2 = r^2
Since we know a point on the circle we know that ...
(7 -3)^2 +(1 +2)^2 = r^2 = 16 +9 = 25
So, the circle's equation is ...
(x -3)^2 +(y +2)^2 = 25 . . . . . matches choice C
__
5) As in the previous problem, the standard form equation is ...
(x -4)^2 +(y -8)^2 = (-1-4)^2 +(7-8)^2 = 25+1 = 26
To put this in general form, we need to subtract 26 and eliminate parentheses.
x^2 -8x +16 +y^2 -16y +64 -26 = 0
x^2 +y^2 -8x -16y +54 = 0
__
6) A circle tangent to the y-axis will have a radius equal to the x-value of the center point.
(x -5)^2 +(y -6)^2 = 5^2
x^2 -10x +25 +y^2 -12y +36 = 25
x^2 +y^2 -10x -12y +36 = 0

Here we have the formula for the area of a triangle: [tex]A = \frac{1}{2}bh[/tex]. Our goal is to isolate h on one side of the equation.
To do this, let’s treat the rest of the equation as if there were no variables.
Multiply both sides by 2:
[tex]2a = bh[/tex]
Divide both sides by [tex]b[/tex]:
[tex]\frac{2a}{b} = h[/tex]

[tex]\boxed {\tt x=3}[/tex]
Step-by-step explanation:
We are given the equation:
[tex]5x-2=3x+4[/tex]
We want to solve for x, therefore we must isolate x on one side of the equation.
First, move all the constants to one side of the equation. 2 is being subtracted from 5x. The inverse of subtraction is addition. Add 2 to both sides.
[tex]5x-2+2=3x+4+2[/tex]
[tex]5x=3x+4+2[/tex]
[tex]5x=3x+6[/tex]
Next, move all the terms with variables to one side. 3x is being added to 6. The inverse of addition is subtraction. Subtract 3x from both sides.
[tex]5x-3x=3x-3x+6[/tex]
[tex]5x-3x=6[/tex]
[tex]2x=6[/tex]
x is being multiplied by 2. The inverse of multiplication is division. Divide both sides of the equation by 2.
[tex]\frac{2x}{2} =\frac{6}{2}[/tex]
[tex]x=\frac{6}{2}[/tex]
[tex]x=3[/tex]
