Answer:
12x - 73
Step-by-step explanation:
DFE + CFD = 12x + 7
DFE + 90 = 12x + 7
DFE = 12x + 7 - 90
DFE = 12x - 83
therefore
DFE = AFB ( vertically opposite angles are equal)
AFB = 12x - 83

Lana had 475 Pokemon cards. She gave her little brother 125 of her cards. What percentage of her cards did Lana give away?
So, Lana gave away 26.32% of he Pokemon cards to her little brother.
To find the percentage of cards Lana gave away, we can use the formula:(Quantity given away / Total quantity) * 100.
In this case, Lana gave away 125 cards out of her total collection of 475 cards.Plugging these values into the formula, we have:
(125 / 475) * 100 = 0.2632 * 100 = 26.32%.
Lana gave away 26.32% of her Pokemon cards to her little brother.
Alternatively, we can calculate the percentage by subtracting the remaining cards from the total and finding the ratio:
Percentage given away
= (Cards given away / Total cards) * 100
= (125 / 475) * 100
= 26.32%.

Step-by-step explanation: Brainliest pls:)
If segment BD is congruent to segment BC, BD=4x-18, BC=x+3, and AC=34, find AB
If segment BD is congruent to segment BC, and BD = 4x - 18, BC = x + 3, and AC = 34, then AB = 31/x.
What is meant by Congruent angles?Congruent angles are two or more angles that are exactly the same. As a result, the lengths of these angles are equal. Angle measurement is the same for congruent angles. A regular pentagon, for example, has five sides and five angles, each of which is 108 degrees. Angles in a regular polygon will always be congruent regardless of size or scale. Congruent angles are another name for equal angles. Angles that are congruent are those that are vertically opposite each other. Congruent angles are those formed by the intersection of two parallel lines and a transversal.Let the equation be AB + BC = AC
substitute the values in the above equation, we get
AB + x + 3 = 34
simplifying the value of x,
Subtract A B from both sides AB + x + 3 - AB = 34 - A B
x + 3 = 34 - AB
Subtract 3 from both sides,
x + 3 - 3 = 34 - AB - 3
x = -AB + 31
Plug in this value of x into the line segments to find BC and AC.
Where, BC = x + 3
substitute the value of x in the above equation, we get
BC = [-AB + 31 ] + 3
BC = -AB + 34
Then, AB + BC = AC
x = -AB + 31
AB = 31/x
Hence, If segment BD is congruent to segment BC, and BD = 4x - 18,
BC = x + 3, and AC = 34, then AB = 31/x.

Answer:
$163
Step-by-step explanation:
Bob worked 26 hours and earn $7 per hour. Multiply 26 with 7:
26 x 7 = 182
Bob made a total of $182 last month.
Bob then spent $19. Subtract 19 from the total earned:
182 - 19 = 163
Bob has $163 left.
~
Answer:
He has $163 dollars left
Step-by-step explanation:
Because first we needed to find out how much did he make in 26 hours, 29 (hours) x $7 (per hour) = $182
Then he spent $19, $182 (how much he made in 26 hours) - $19 (how much he spent) = $163

if a = 1 3 5 and b equals to 1 3 5 find a into B and Plot the co-ordinate in graph paper
To find the result of multiplying vector a by vector b, we use the dot product or scalar product. The dot product of two vectors is calculated by multiplying the corresponding components and summing them up.
Given:
a = [1, 3, 5]
b = [1, 3, 5]
To find a · b, we multiply the corresponding components and sum them:
\(a . b = (1 * 1) + (3 * 3) + (5 * 5)\\ = 1 + 9 + 25\\ = 35\)
So, a · b equals 35.
Now, let's plot the coordinate (35) on a graph paper. Since the coordinate consists of only one value, we'll plot it on a one-dimensional number line.
On the number line, we mark the point corresponding to the coordinate (35). The x-axis represents the values of the coordinates.
First, we need to determine the appropriate scale for the number line. Since the coordinate is 35, we can select a scale that allows us to represent values around that range. For example, we can set a scale of 5 units per mark.
Starting from zero, we mark the point at 35 on the number line. This represents the coordinate (35).
The graph paper would show a single point labeled 35 on the number line.
Note that since the coordinate consists of only one value, it can be represented on a one-dimensional graph, such as a number line.

In general, any symmetrical object will have a net torque of zero if the axis of rotation is through its center of mass.
It seems that the list of examples is missing from your question, so I'll provide a general explanation of situations where the net torque is zero. Please feel free to provide a list of examples for a more specific answer.
A net torque of zero about an axis perpendicular to the page and extending from the center means that the total clockwise torque is equal to the total counterclockwise torque. This can occur when:
1. There are no external forces acting on the system, so there is no torque.
2. The external forces are acting along the line of the axis, causing no rotation and hence no torque.
3. The clockwise and counterclockwise torques cancel each other out, resulting in a net torque of zero.
Some examples of objects that have a net torque of zero about the axis perpendicular to the page and extending from the center of the object are a sphere, a cube, a cylinder, and a cone.
Please provide the list of examples you'd like me to evaluate, and I'll be glad to help you determine which have a net torque of zero.

where would you put the decimal point in 201 x 15 to make it equal 30.15
201 x 15 = 30.15
Answer:
2.01 x 15 = 30.15
Step-by-step explanation:
2.01 x 15 = 30.15
or
201 * .15 = 30.15
Answer:
201 changes to 2.01 or 15 changes to 0.15
2.01 · 15 = 30.15
201 · 0.15 = 30.15
Step-by-step explanation:
Since 201 · 15 = 3015, and we want 30.15
We move the decimal two place to the left.
Since we did this on one side of the equation, we must do it on the other as well.
201 becomes 2.01. You could also change 15

Joaquín compró una docena y media de factura la docena son parte de grasa dos tercios tiene dulce de leche y el resto son medialunas cuántas son de grasa Cuánto tiene dulce de leche Cuántas medialunas compró
Answer:
2 facturas de grasa.
12 facturas con dulce de leche
4 medialunas
Step-by-step explanation:
Una docena contiene 12 facturas y media docena contiene 6 facturas. Entonces Joaquin compro un total de 18 facturas (12+6). Si la novena parte (1/9) de las facturas son de grasa entonces solo multiplicamos esta fraccion por la totalidad de las facturas.
18 * (1/9) = 2 facturas de grasa.
La cantidad de facturas que tienen dulce de leche son dos tercios (2/3) de la totalidad. Entonces multiplicamos esta fracion for la totalidad.
18 * (2/3) = 12 facturas con dulce de leche
Por final, la cantidad de media lunas es el resto de las facturas, entonces descontamos las facturas de grasa y con dulce de leche de la totalidad para saber cuantas facturas son medialunas
18 - 2 - 12 = 4 medialunas

correlation will not show whether or not there is weight loss. which tool would be more appropriate?
The following ways of measuring weight loss are more appropriate than correlation, i.e.,Skin calipers, Impedance scales, DEXA scanning, Body measurements.
What is meant by weight loss?Calories factor into the equation while trying to maintain a healthy weight. The key to losing weight is to burn more calories than you consume. You may do this by consuming fewer calories than you need and increasing the number of calories you burn via physical exercise.
A realistic, efficient, and lasting weight loss plan might be difficult to follow even if it may appear straightforward.
You don't have to do it by yourself, though. Seek advice from your doctor, family, and friends. Consider whether this is the right time and whether you're prepared to make the essential changes.

Result: \(\boldsymbol{20}\)
The result is rational because it can be written as the ratio of two integers and its decimal expansion does terminate or repeat.
=============================================
Explanation:
Let's simplify the expression to get...
\(2\sqrt{16}+4\sqrt{9}\\\\2\sqrt{4^2}+4\sqrt{3^2}\\\\2*4+4*3\\\\8+12\\\\20\\\\\)
Therefore, \(2\sqrt{16}+4\sqrt{9}=20\\\\\)
Since \(20 = \frac{20}{1}\), we have a rational number here. It's a fraction of two integers
\(\text{rational number} = \frac{\text{integer}}{\text{integer}}\)
We cannot have zero in the denominator.
One property of rational numbers is that the decimal expansion either terminates or it repeats (one option only).
In this case, we have a terminating decimal because 20 = 20.0; ie the decimal doesn't go on forever.
In contrast, something like 1/3 = 0.33333... has the '3's go on forever to be a repeating decimal.

Rose uses 8.3 pints of white paint and blue paint to paint her bedroom walls. 3 4 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?
Answer: Rose used 2.075 pints of blue paint for her bedroom walls
Step-by-step explanation:
Amount of white and blue paint used for bedroom walls=8.3 pints
Amount of white paint used =3/4 x8.3 pints =6.225 pints
Amount of blue paint used = Amount of white and blue paint used for bedroom walls-Amount of white paint used
8.3 pints - 6.225 pints=2.075 pints
The work W required to move a particle from a far distance to within radius r of another particle varies jointly as the product of the two particles' charges q1 and q2 and inversely as the radius r. Write a formula that models this proportion. (Use k as the constant of variation.)
Answer:
W = kq1q2 / r
Step-by-step explanation:
W varies jointly as the product of q1 and q2 and inversely as radius r
Product of q1 and q2 = q1q2
W = (k*q1"q2) / r
W = kq1q2 / r
Where,
W = work
q1 = particle 1
q2 = particle 2
r = radius
k = constant of proportionality
The answer is W = kq1q2 / r
Using proportions, it is found that the formula is:
\(W = k\frac{q_1q_2}{r}\)
Work varies jointly as the charges, thus, the charges are in the numerator.Inversely as the radius, thus, the radius is in the denominator.There is a constant of proportionality k, which multiplies the fraction;Then, the formula is:
\(W = k\frac{q_1q_2}{r}\)
