Parallelogram ABCD is shown. Point E is the midpoint of segment AB. Point F is the midpoint of segment CD.

Which transformation carries the parallelogram onto itself?

a reflection across line segment AC

a reflection across line segment EF
a rotation of 180 degrees clockwise about the origin

a rotation of 180 degrees clockwise about the center of the parallelogram

For the length of BC = 8 cm which represents 200%, the length of a line segment that is 75% is 3cm.

The length of a line segment that is 75% can be calculated by using a proportion. If BC represents 200% and has a length of 8 cm, and let length of a line segment that is 75% be x, then we can set up the following proportion:

200%/8 cm = 75%/x cm

Cross-multiplying gives us:

200% * x cm = 75% * 8 cm

Simplifying gives us:

x = (75% * 8 cm) / 200%

x = 3 cm

Therefore, the length of a line segment that is 75% is 3 cm.

Note: The question is incomplete. The complete question probably is: The length of BC is 8 cm. If BC represents 200%, what is the length of a line segment that is 75%.

A. 1/6

B. 1

Step-by-step explanation:

A. 9/j x j/54= 9/54 = 1/6

B. 6k/8m : 3k/4m = 6k/8m : 4m / 3k = 2/2 =1

Answer:

a. 3/2

b. 1

Step-by-step explanation:

A. To simplify the expression, we can cancel out the common factor of j:

9/j * j/54 = (9/1 * 1/6) = 3/2

Therefore, 9/j * j/54 simplifies to 3/2.

B. To divide fractions, we can multiply the first fraction by the reciprocal of the second fraction. That is,

(a/b) ÷ (c/d) = (a/b) x (d/c)

Using this rule, we can simplify the given expression as follows:

6k/8m ÷ 3k/4m = (6k/8m) x (4m/3k)

             = (6/8) x (4/3)  

             = 2/2

             = 1

Given: The fence costs $1.50 per footTo find: The shortest possible length for a side of the flower bed.

Step 1: The perimeter of the triangle flower bed Perimeter of the triangular flower bed = AB + AC + BC ftAB = a ftAC = aftBC = (a + 4) ftPerimeter = a + aft + (a + 4)ft = 2a + 5ft

Step 2: The cost of the fence The cost of the fence = $1.50/foot × (Perimeter)

The compound inequality can be written as:60 ≤ $1.50/foot × (2a + 5ft) ≤ 75

Divide the whole inequality by 1.5.40 ≤ 2a + 5ft ≤ 50

Subtracting 5 from all sides:35 ≤ 2a ≤ 45Dividing by 2, we get:17.5 ≤ a ≤ 22.5

Therefore, the shortest possible length for a side of the flower bed is 17.5 feet.

Answer:

Y=75x+125

Step-by-step explanation:

Your answer is correct. It is c. The equation is y=Mx+b where m is the slope and b is the y intercrept.

To get M (the slope), get the difference of y-y/x-x. You can use any value of y and x. So, 575-500/6-5=75/1 ot 75. Therefore 75 is m in the equation y=Mx+b.

To get b, you figure out what y is when x is 0. So, looking at the numbers, subtract 75 from 350, which means that  y is 275 when x is 2. Subtract 75 again to get 200 (275-75) when x is 1. Subtract 75 one more time to get y when x is 0. 200-75=125. 125 is the y intercept.

Going back to the equation y-Mx+b. Fill in m and b. Y=75x+125.

The work done on a 28.0 kg crate initially moving with a velocity of 4.20 m/s at 37.0∘ west of north to change its velocity to 5.62 m/s at 63.0° south of east is 309 Joules.

To solve this problem, we need to use the work-energy principle, which states that the work done on an object is equal to the change in its kinetic energy. The formula for kinetic energy is

KE = 1/2mv^2

where m is the mass of the object, and v is its velocity.

We can find the initial kinetic energy of the crate using its initial velocity

KE1 = 1/2(28.0 kg)(4.20 m/s)^2

KE1 = 249 J

We can also find the final kinetic energy of the crate using its final velocity

KE2 = 1/2(28.0 kg)(5.62 m/s)^2

KE2 = 558 J

The change in kinetic energy is therefore:

ΔKE = KE2 - KE1

ΔKE = 558 J - 249 J

ΔKE = 309 J

Since the work done on the crate is equal to the change in its kinetic energy, we can find the work using

W = ΔKE

W = 309 J

Therefore, the amount of work that must be done on the crate to change its velocity is 309 Joules.

The moment of inertia of a cube with mass m = 0.500kg and side lengths s = 0. 030m about an axis which is both normal (perpendicular) to and through the center of a face of the cube is I = 2.205x10^-4 kg/m^2.

Here Given mass m = 0.5 kg

And side length = 0.03 m

Moment of inertia I = mass x radius of rotation squared

I = mr^2

In this case, the radius of rotation is about an axis which is both normal (perpendicular) to and through the center of a face of the cube.

Calculating from the dimensions of the the box, the radius of rotation r = 0.021 m

Therefore, I = 0.5 x 0.021^2 = 2.205x10^-4 kg/m^2

Hence the answer is the moment of inertia of a cube with mass m = 0.500kg and side lengths s = 0. 030m about an axis which is both normal (perpendicular) to and through the center of a face of the cube is I = 2.205x10^-4 kg/m^2.

The solutions of the given quadratic equation 8x² = 6 + 22x will be x = -1/4 and x = 3 thus, option (B) and (C) is correct.

An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, and a must not be zero.

For example, 3x² + 6x + 8 = 0 here x has the highest term as 2 and the coefficient of x² is not zero.

As per the given quadratic equation,

8x² = 6 + 22x

The roots must satisfy the above equation,

8(-3)² = 6 + 22(3)

72 = 72

And,

8(-1/4)² = 6 + 22(-1/4)

8/16 = 6 - 11/2

1/2 = 1/2

LHS = $2000

RHS =

so LHS NOT EQUAL TO RHS HENCE THE INTEREST GIVEN IS NOT CORRECT

SI = interest + principle

SI = 163.3632 + 29.92

Answer:

218.57

Step-by-step explanation:

Since it is an isoceles triangle, the sides are 32, 32, and 14.

Using Heron's Formula, which is Area = sqrt(s(s-a)(s-b)(s-c)) when s = a+b+c/2,  we can calculate the area.

(A+B+C)/2  = (32+32+14)/2=39.

A = sqrt(39(39-32)(39-32)(39-14) = sqrt(39(7)(7)(25)) =sqrt(47775)= 218.57.

What is an angle?

An angle is a shape made up of two rays that share an endpoint and is known as the vertex of the angle. These rays are known as the sides of the angle. The plane that contains the rays contains the angles created by two rays. The meeting of two planes can also result in an angle. They are referred to as dihedral angles.

The orientation of a line with another line or plane is represented by its angular position. How far the body has been rotated from the reference position is used to measure angular position.

The current when the resistance is 90 ohms is 2.7 amperes (rounded to one decimal place), with units of amperes.

The relationship between current and resistance is given by the equation I = V/R, where I is the current in amperes, V is the voltage in volts, and R is the resistance in ohms. If we assume that the voltage is constant, then we can use the fact that the current is inversely proportional to the resistance to find the current when the resistance is 90 ohms.

To do this, we can use the formula I1R1 = I2R2, where I1 and R1 are the initial current and resistance, and I2 and R2 are the final current and resistance. Plugging in the values given, we get:

1.2 A x 200 ohms = I2 x 90 ohms

Simplifying, we get:

I2 = (1.2 A x 200 ohms) / 90 ohms

I2 = 2.67 A

Therefore, the current when the resistance is 90 ohms is 2.7 amperes (rounded to one decimal place), with units of amperes.

The chances that the coin is unbiased are 0.08 or 8%.

Probability is the measure of the likelihood of an event occurring.

Probability is calculated by dividing the number of successful events by the total number of possible events.

The probability of an event ranges between 0 and 1.

An event with a probability of 0 has no chance of occurring, whereas an event with a probability of 1 is certain to occur.

In the given question, a coin was tossed 500 times.

The result was heads 230 times and tails 270 times.

Let us calculate the probability of getting heads when the coin is tossed.

P(h) = Probability of getting heads = Number of heads/Total number of tosses = 230/500 = 0.46

Similarly, let us calculate the probability of getting tails when the coin is tossed.

P(t) = Probability of getting tails = Number of tails/Total number of tosses = 270/500 = 0.54

The coin is unbiased if the probability of getting heads is equal to the probability of getting tails when the coin is tossed.

P(h) = P(t)0.46

= 0.54 0.54 - 0.46

= 0.08

Thus, the chances that the coin is unbiased are 0.08 or 8%.
