Answer:

12%

Step-by-step explanation:

Your equation would be 160=2000xRx2/3 (8 months=2/3

First, multiply 2000x2/3 which equals 1333.33

So now we have 160=1333.33r

Second, divide 160 by 1333.33 which equals 0.1200003

Lastly, move the decimal two spots over to get your percent which is 12%

Answer:

[tex]I=\frac{P}{V}[/tex]

Step-by-step explanation:

We are given the equation [tex]P=I*V[/tex], and we need to solve the equation for [tex]I[/tex]. Solving an equation for a variable means that we manipulate the equation so it is in the form (variable being solved for) = ?, where the ? is any expression.

To solve for [tex]I[/tex], we need to isolate the variable. This is the process of getting the equation into the form mentioned above by essentially getting all [tex]I[/tex] terms on one side and all [tex]\text non-I[/tex] terms on the other side.

In this case, we need to "get rid" of the [tex]V[/tex] from the right-hand side (RHS). Notice that it is being multiplied by the variable we are solving for. Therefore, to remove it from the RHS, we will need to perform the opposite operation, which is division. We will use what's called the Division Property of Equality to do this, which states that in order to maintain equality, you need to divide both sides of an equation by the same number.

Dividing both sides by [tex]V[/tex], we get:

[tex]P=I*V[/tex]

[tex]\frac{P}{V}=\frac{I*V}{V}[/tex]

[tex]\frac{P}{V} = I[/tex] (simplify RHS)

[tex]\bf I=\frac{P}{V}[/tex] (this uses the Symmetric Property of Equality - if a = b then b = a)

Answer:

A. 260°

Step-by-step explanation:

The measure of the arc in the circle given is 260°

A circle is the set of all points in the plane that are a fixed distance (the radius) from a fixed point (the centre). Any interval joining a point on the circle to the centre is called a radius. By the definition of a circle, any two radii have the same length.

Given is a circle, with an inscribed angle of 50°, we need to find the arc ABC,

So, according to the inscribed angle theorem,

∠ BAC = 1/2 arc BC

So, arc BC = 2 x ∠ BAC

arc BC = 2 x 50

∠ BAC = 100°

Now,

arc ABC = 360° - arc BC

Since, we know that the whole circle, measures 360°

So,

arc ABC = 360° - 100°

arc ABC = 260°

Hence, the measure of the arc in the circle given is 260°

Answer:

Step-by-step explanation:

By the Isosceles Triangle Theorem, if 2 sides of a triangle are congruent to each other, than the angles opposite those sides are also congruent. We see by the markings on the triangle that WX and WY are congruent. That means that angle Y (which is across from WX) and angle X (which is across from WY) are the same measure. We can set them equal to each other  because of this:

6y - 2 = 4x + 20

But we have a problem because we have 2 unknowns.

Let's try this out: the Triangle Angle-Sum Theorem says that all the angles of a triangle have to add together to equal 180. That means that

52 + 6y - 2 + 4x + 20 = 180.

But we STILL have a problem with those 2 unknowns. BUT...

If angle X and angle Y are the same, then we don't need both 6y - 2 AND 4x + 20.  We only need 1 of those multiplied by 2 because they're the same measure. Changing things up a bit to reflect that:

52 + 2(4x + 20) = 180 and

52 + 8x + 40 = 180 and

8x = 88 so

x = 11.

That means that

4(11) + 20 = 64 which is the measure of both angles X and Y.

Let's check:

64 + 64 + 52 better equal 180. And it does, so we're good.

The value of x is found this way:

4x + 20 = 64 and

4x = 44 so

x = 11 which we already knew. Now for y:

6y - 2 = 64 and

6y = 66 and

y = 11 also.

Answer:

Amount of string let out by Jim will be 156.9 m.

Step-by-step explanation:

Distance between Jim and Patty = 200 m

Angle of elevation of the kite from Jim = 85°

Angle of elevation of the kite from Patty = 40°

Angle between the lines joining Jim and kite and Patty and the kite = 180° - (85 + 40)° = 55°

By applying Sine rule in the triangle formed by the kite, Jim and Patty,

[tex]\frac{\text{sin}55}{200}=\frac{\text{sin}40}{x}[/tex]

x = [tex]\frac{200\times \text{sin}40}{\text{sin55}}[/tex]

x = 156.94

  ≈ 156.9 m

Therefore, amount of string let out by Jim will be 156.9 m.

SV = 41 units

QT = 21 units

Step-by-step explanation:

Please refer to the attached figure.

It is given that line segment TV has a perpendicular bisector as line N which intersects on line on TV at point R.

So, TR = RV

We are given that:

[tex]RV = 3 x + 2\\QV = 4 x + 1\\TS =9 x -4 \\TR = 17\ units[/tex]

Comparing the values of TR and RV:

[tex]3x +2=17\\\Rightarrow x = 5[/tex]

We can easily observe that due to the nature of the construction of this figure there is symmetry present.

As a result, we can draw the following conclusions:

1. [tex]QT = QV = 4x+1\\[/tex]

Putting value [tex]x=5[/tex]:

[tex]QT = 4\times 5+1\\\Rightarrow QT =21\ units[/tex]

2. [tex]TS =SV = 9x-4[/tex]

Putting value [tex]x=5[/tex]:

[tex]\Rightarrow SV = 9 \times 5-4\\\Rightarrow SV = 41\ units[/tex]

Answer:

16 millimeters

Step-by-step explanation:

Now:

Volume of a Prism=Base Area X Prism Length

Since we have a triangular base:

Volume of the Prism=(0.5 X Base X Height) X Prism Length

Substituting the given values, we obtain:

416=(0.5 X 13 X Height) X 4

416=26 X Height

Divide both sides by 26

Height of its triangular face=16 millimeters

Answer:

h = 16 mm

Step-by-step explanation:

Th volume of the prism is:

[tex] V = A*l [/tex] (1)

Where:

V. is the volume of the triangular prism = 416 mm³

A. is the area of the prism = ?

l: is the large of the prism = 4 mm

The area of the triangular face of the prism is:

[tex] A = \frac{1}{2}bh [/tex]  (2)

Where:

b: is the base of the triangular face = 13 mm

h: is the height of the triangular face = ?

From equation (1) we have:

[tex] V = A*l [/tex]

[tex] A = \frac{V}{l} = \frac{416 mm^{3}}{4 mm} = 104 mm^{2} [/tex]

Now, using equation (2) we can find the height of the triangular face:

[tex] A = \frac{1}{2}bh [/tex]

[tex] h = \frac{2A}{b} = \frac{2*104 mm^{2}}{13 mm} = 16 mm [/tex]

Therefore, the height of the triangular face is 16 mm.

[tex]=(5x+3)(5x+3)[/tex]

Answer:

[tex]=(5x+3)(5x+3)[/tex]

Answer: C. (5x+3)(5x+3)

Step-by-step explanation:

This is assuming this is a quadratic with 25x2 actually being 25x^2

We can start by simplifying the 25 to be 5^2

As well as the 9 to be 3^2

The expression now looks like: [tex]5^{2}x^{2} + 30x + 3^2[/tex]

Now we can apply an exponent rule to the 5^2 x^2

The rule states: [tex]a^{m}b^{m} = (ab)^m[/tex]

So this means: [tex]5^{2}x^{2} = (5x)^2[/tex]

We can now rewrite 30x as 2 * 5x * 3

The expression now looks like: [tex](5x)^{2} + 2 * 5x * 3 + 3^{2}[/tex]

Now this expression matches with the perfect square formula which states:

[tex](a+b)^{2} = a^{2} +2* a * b + b^{2}[/tex]

Our a value is 5x and our b value is 3.

So: [tex](a+b)^{2} = (5x+3)^{2}[/tex]

The answer is (5x+3)(5x+3)

Given the circle: [tex](x + 7)^2 + (y - 10)^2 = 13^2[/tex]

The point (x,y) which lie on the circle are the coordinate which satisfies the given equation of the circle.

We now consider the given options.

Option A (5,12)

When x=5, y=12

[tex](5 + 7)^2 + (12 - 10)^2 =12^2+2^2=148\neq 169= 13^2[/tex]

Option B (-7,-3)

When x=-7, y=-3

[tex](-7 + 7)^2 + (-3 - 10)^2 =0^2+(-13)^2= 169=13^2[/tex]

Option C (-6,-10)

When x=-6, y=-10

[tex](-6 + 7)^2 + (-10 - 10)^2 =1^2+(-20)^2=401\neq 169= 13^2[/tex]

Option D (6,23)

When x=6, y=23

[tex](6 + 7)^2 + (23 - 10)^2 =13^2+13^2=338\neq 169= 13^2[/tex]

We can see that only (-7,-3) satisfies the equation of the circle. Thus it is the point which lies on the circle.

The correct option is B.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 4 is an equation

3x + 5 = 3 is an equation

We have,

3x + 2 = (2x + 13) / 3

Multiply both sides by 3.

3 x (3x + 2) = 2x + 13

Remove the parentheses.

(3 x 3x) + 3 x 2 = 2x + 13

9x + 6 = 2x + 13

Subtract 2x on both sides.

9x + 6 - 2x = 13

7x + 6 = 13

Subtract 6 on both sides.`

7x + 6 - 6 = 13 - 6

7x = 7

Divide 7 on both sides.

x = 1

Thus,

The value of x after solving the equation is 1.
