Carolyn is 6 years older than alfred. six years ago she was twice as old as him. how old is each now?

Answer: i can answer the first one but the second one i might get wrong

Step-by-step explanation:

for the first question answer B because external lights do not help unless it is dark, you need your battery to start the car and your fluids to keep the car running, your windshield's keep the raid and weather from entering your car as well as stopping you from flying out the window. Your mirrors help you keep track of whats behind you and showing you if you have enough space to turn.

now for the second question i would say in the manual of your car because every car has a manual to read on how to work the car/fix it

Answer:

It would fall on the upper line.

Step-by-step explanation:

I can look at each line and see the equation for each.

The equation for the upper line y = x + 5 and the equation for the lower line is y = x - 3. I then substitute the aforementioned point into each equation and see which is correct. The point is a solution of the first equation, therefore it falls on the upper line.

Answer: False

Step-by-step explanation:

To determine if (1, -1) is a solution to the inequality y > -4x + 6, we need to substitute x = 1 and y = -1 into the inequality and see if it is a true statement.

-4(1) + 6 = 2, so the inequality becomes -1 > 2.

This is false, so (1, -1) is not a solution to the inequality y > -4x + 6.

Therefore, the statement is False.

Answer:

  x = 12

Step-by-step explanation:

Tangents to a circle from a common point are the same length:

  4x -7 = 2x +17

  2x = 24 . . . . . . . . add 7-2x

  x = 12 . . . . . . . divide by 2

Variable: y

Sum: (4y + 8) ÷ 6 – 12

Quotient: (4y + 8) ÷ 6

The measure of [tex]\angle D[/tex] is 13.

Vertical angles are formed when two lines meet each other at a point. They are always equal to each other.

given:

[tex]m\angle C=-3x+58[/tex] and [tex]m\angle D=x-2[/tex]

As, [tex]\angle C[/tex] and [tex]\angle D[/tex] are vertical angles

so,

[tex]m\angle C= m\angle D[/tex]

[tex]-3x+58 = x-2[/tex]

[tex]-3x -x = -2-58[/tex]

[tex]-4x = -60[/tex]

[tex]x= 15[/tex]

So, [tex]m\angle D= x-2= 15-2 = 13[/tex]

The required perimeter of the given triangle EFG is 25.7 units.

A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes.

Triangle ABC is the designation for a triangle with vertices A, B, and C.

In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.

The easiest approach I've found to know for sure if an angle is 90 degrees is to use the 3:4:5 triangle.

So, the formula that will be used here would be:

d = √(y₂-y₁)²+(x₂-x₁)²

Get EF:

E(-8,1) = (x1, y1)

F(1,1) = (x2, y2)

Substitute the values:

EF = √[(1−(−8))² + (1−1)²]

EF = √[(9)² + (0)²]

EF = √81

EF = 9 units

Get FG:

F(1,1) = (x1, y1)

G(-3,8) = (x2, y2)

Insert the values as follows:

FG = √[(−3−1)² + (8−1)²]

FG = √[(−4)² + (7)²]

FG = √65

FG ≈ 8.1 units

Obtain EG:

E(-8,1) = (x1, y1)

G(-3,8) = (x2, y2)

Insert the values:

EG = √[(−3−(−8))² + (8−1)²]

EG = √[(5)² + (7)²]

EG = √74

EG ≈ 8.6 units

Perimeter of triangle EFG = 9 + 8.1 + 8.6

The perimeter of triangle EFG = 25.7 units

Therefore, the required perimeter of the given triangle EFG is 25.7 units.

The required perimeter of the given figure is 68 units.

A boundary is a closed path that encloses, surrounds, or outlines either a two-dimensional shape or a one-dimensional length.

The circumference of a circle or ellipse is called the perimeter.

Perimeter calculations have several practical applications.

Perimeter is the distance around the object.

For example, your house has a fenced garden.

The perimeter is the length of the fence.

If the yard is 50 feet by 50 feet, the fence length will be 200 feet.

So, the perimeter of the given figure:

= 10 + 4 + 2 + 12 + 6 + 6 + 6 + 2 + 12 + 4 + 4

= 68 units

Therefore, the required perimeter of the given figure is 68 units.

Step-by-step explanation:

We need to divide the distances into  2+3 segments then add two of these as follows

for x   from   -5 to 6 is +11   divide by 5  = +11/5  add two of these to -5 to get   x = -0.6

The tax rate for social security is 6.0%, and the amount of wages subject to this tax is $350,000, Social security tax =$21,000 , Medicare tax = $5,250 , State unemployment tax =$2,835 , Federal unemployment tax =  $420 and Total taxes = $29,505 .

To calculate the amount of taxes that Widmer Company owes for the week ended June 17, we need to calculate each tax separately and then add them together.

First, let's calculate the social security tax. The tax rate for social security is 6.0%, and the amount of wages subject to this tax is $350,000. So:

Social security tax = 6.0% x $350,000 = $21,000

Next, let's calculate the Medicare tax. The tax rate for Medicare is 1.5%, and the amount of wages subject to this tax is also $350,000. So:

Medicare tax = 1.5% x $350,000 = $5,250

Now let's calculate the state unemployment tax. The tax rate for state unemployment is 5.4%, and the amount of wages subject to this tax is $52,500. So:

State unemployment tax = 5.4% x $52,500 = $2,835

Finally, let's calculate the federal unemployment tax. The tax rate for federal unemployment is 0.8%, and the amount of wages subject to this tax is also $52,500. So:

Federal unemployment tax = 0.8% x $52,500 = $420

Now let's add up all of the taxes:

Total taxes = Social security tax + Medicare tax + State unemployment tax + Federal unemployment tax

Total taxes = $21,000 + $5,250 + $2,835 + $420

Total taxes = $29,505

This means that Widmer Company owes $29,505 in taxes for the week ended June 17.

Additionally, we are told that the total amount withheld from employee wages for federal taxes was $70,000. This means that the company must remit this amount to the federal government as federal income tax on behalf of its employees. The $70,000 does not affect the company's own tax liability, but rather is an amount owed to the federal government by the employees themselves.

We can write an equation:

7x + 4 = 8x - 20

subtract 7x from both sides.

4 = x - 20

add 20 to both sides

24 = x

Then, the question asks for the measure of AngleB.

AngleB

Based on inductive reasoning the next two numbers in pattern -243 and 729.

Based on inductive reasoning:

The given pattern seems to be based on multiplication by -3. Each term in the sequence is obtained by multiplying the preceding term by -3. Specifically, to get from 9 to -27, we multiply 9 by -3; to get from -27 to 81, we multiply -27 by -3, and so on.

Using this pattern, we can find the next two numbers in the sequence as follows:

To find the 5th term, we need to multiply the 4th term (81) by -3. Thus, the 5th term will be -243.

To find the 6th term, we need to multiply the 5th term (-243) by -3. Thus, the 6th term will be 729.

The next two numbers in the pattern are -243 and 729.

We can also express this pattern using a recursive formula, where nth term is given by:

2. Number of microstates consistent with the macrostate 6 Heads and 1 Tails is (d) 7.

Let's discuss it further below.

(a) To find the probability of observing the microstate HHTHHH, you need to calculate the probability of getting each result in the sequence. Since it is a fair coin, the probability of getting heads (H) is 1/2 and tails (T) is also 1/2.

Step 1: Calculate the probability for HHTHHH.
Probability = (1/2)⁶ = (1/64) = 0.015625 = 1.56e-02

So, the answer for the probability of observing the microstate HHTHHH is (a) 5.47e-02.

(b) To find the number of microstates consistent with the macrostate 6 Heads and 1 Tails, you need to find the number of ways to arrange 6 H's and 1 T in a sequence of 7 coin tosses.

Step 2: Use combinations formula: C(n, k) = n! / (k!(n-k)!)
In this case, n=7 (total coin tosses) and k=6 (number of heads).

C(7, 6) = 7! / (6!(7-6)!) = 7! / (6!1!) = 7

So, the answer for the number of microstates consistent with the macrostate 6 Heads and 1 Tails is (d) 7.
