Answer: $173.96

Step-by-step explanation: If I'm not mistaken first you have to take 106 and multiply it by 2 to count for the round trips so that makes 212 miles for one trip, then you have to multiple by 8 to figure out how many miles in total which equals  1696, then you divide by the 35 to figure out how many gallons she use, which is 48.457(rounded) then you multiple that by the rate of gas which is 3.59 which means she spent 173.96(rounded to the nearest tenth)

Answer:

See below

Step-by-step explanation:

Present Value = 400

Period = 1 month      8 years is    n =   96 periods

Interest per period in decimal form     i =  .076 / 12 = .0063333

Fv = PV ( 1 + i)^n  

Fv = 400 ( 1 + .076/12)^96 = 733.29 dollars

4. The greatest change in elevation is on Checkpoint 4.

5. The change in elevation on the final checkpoint is of: -62.1 feet.

The change in elevation for each checkpoint is given by the subtraction of the final elevation by the initial elevation. Both these elevations are given on the table.

Hence, for each checkpoint, the changes are given as follows:

Hence the greatest change is of 210.4 feet on checkpoint 4.

The final elevation is of 148.3 feet, hence the change in elevation on the final stage is obtained as follows:

148.3 - 210.4 = -62.1 feet.

The amount of loan after 2 years will be $6491.4.

What is Simple interest?

A quick and easy method of calculating the interest charge on a loan is called a Simple interest.

Given that;

Interest rate = 4.5%, compounded continuously.

Time = 2 years

Initial value = $3100

Now,

We know that;

The formula for amount after continuous compound interest is,

⇒ [tex]A = P e^r^t[/tex]

Where,  P is principal, r is rate per year, t is time in year.

Substitute all the values, we get;

⇒ [tex]A = P e^r^t[/tex]

⇒ [tex]A = 3100 e^{0.045 * 2}[/tex]

⇒ [tex]A = 3100 e^{0.09[/tex]

⇒ [tex]A = 3100 * 1.094[/tex]

⇒ [tex]A = 6491.4[/tex]

Thus, The amount of loan after 2 years will be $6491.4.

Answer:

(a.):  m∠ ACB = 40°; (b.):  m ∠CBA = 25°; (c.):  m ∠CAB = 115°

Step-by-step explanation:

Because Lines AB and DE are parallel, we can use the angle relationships to find the angles.

(For context of the problem, we can label the 40° angle as ∠C and the 155° as ∠B)

(a.) Angles C and ACB are vertical angles, which means they're congruent.  Thus m ∠ACB = 40°.

(b.) AB is a straight line and angles B and CBA are supplementary angles.  This means their total sum is 180°.  We need to subtract angle B from 180 to find m ∠CBA:

[tex]180-155=CBA\\25=CBA[/tex]

(c.) We know that the sum of all the angles is 180°.  Thus, we can subtract the sum of angles CBA and CBA from 180 to find the m ∠CAB:

[tex]180-(40+25)=CAB\\180-65=CAB\\115=CAB[/tex]

Answer:

Equation: y = -4x + 1

Slope: -4

Y-intercept: y = 1

Step-by-step explanation:

To find the equation of the line you need the gradient and the y-intercept

To find the gradient we need to divide the change in y by the change in x:

As the graph has a negative correlation the gradient would have a minus which is why it would be -4!

To find the y-intercept we need to find the number on the y-axis that the line crosses which in this case would be y = 1!!

Hope this helps, have a great day!!

Answer:

equation:y=4x+1

y-intercept:1

slope:4/1 or 4

Step-by-step explanation

the equation has to be in slope intercept form which is [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept. the y-intercept is when x is 0 in this case when x is 0 y is 1 (0,1) so the y-intercept is 1. the slope is rise/run so pick two points that cross the grid perfectly and count the units rise and run. this line rises 4 and runs 1 so the slope is 4/1 so 4 hence the equation [tex]y=4x+1[/tex]

The value of x is 10, in the diagram, Vertically opposed angles

What is Vertically opposed angles?

Two lines intersecting at a point create vertical angles. Every time they are on an equal footing. Alternatively stated, four angles are created anytime two lines cross or intersect. Two opposed angles are equal and are referred to as vertical angles, as we can see. Due to their position opposite one another, they are also known as "Vertically opposed angles."

Angles that are vertically opposed to one another at a certain vertex are formed by two straight lines intersecting. The equality of the vertically opposed angles has been established.

Here in the diagram 5x = 2y

y = 5X/2

We have 2y+2y+8x = 180 in a straight line.

So 4y+8x = 180

4(5x/2) +8x = 180

10x+8x = 180

x = 180/18

x = 10

Hence, the value of x is 10, in the diagram.

Answer:

The y-intercept is 12

Step-by-step explanation:

the equation is: x - 1/2y = -6

We need to find the y-intercept which is the y value when x=0.

Knowing that, we can just substitute 0 for x to get:

0 - 1/2y = -6

From there, it's just algebra so:

0 - 1/2y = -6

-1/2y = -6

-0.5y = -6

y = 12

0.7778 = 77.78%.

The mass probability formula is presented as follows:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are listed as follows:

In this problem, the values of these parameters are listed as follows:

The probability of having at least one white one is:

P(X > 0) = 1 - P(X = 0).

In which:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 0) = h(0,10,5,2) = \frac{C_{2,0}C_{8,5}}{C_{10,5}} = 0.2222[/tex]

The answer is earthquakes: open up large cracks in Earth’s crust tsunamis: erosion of beaches.

What is tsunamis?

Giant waves that are brought on by ocean floor movement are known as tsunamis. Landslides, underwater volcanic eruptions, earthquakes, and even meteorite collisions can cause the ocean floor to tremble. These are often referred to as seismic sea waves, albeit they are sometimes misidentified as tidal waves. A tsunami is a set of waves that are caused by a disturbance in the ocean or another body of water, such as an earthquake, landslide, volcanic eruption, or meteorite strike.

Mr. Baker moves 2 meters per second while standing on the moving sidewalk, and he walked 20 meters to get to the moving sidewalk. which is the correct answer would be an option (C).

Distance is defined as the product of speed and time.

The function shows Mr. Baker's distance (d), in meters, from the check-in counter while he has been standing on the moving sidewalk for s seconds. d = 2s + 20.

Here He travels at a speed of two meters per second while standing on the moving sidewalk, and he walked 20 meters to get there.

The equations for Mechanic G is y = 30x and for mechanic K is y = 20x + 30

Rate is a ratio that compares two different quantities which have different units. For example, if we say John types 50 words in a minute, then his rate of typing is 50 words per minute. The word "per" gives a clue that we are dealing with a rate.

for mechanic G since he charges 30 dollars per hour, for x hours his charge will be 30x

so that y = 30x

For K since he charges at rate of 20 dollars per hour, his charge after x hours will be 20x. if he takes 30 dollars reservation fee

then his total cost is y = 20x + 30

In conclusion, the equations for mechanic G and K are y = 30x and y = 20x + 30 respectively.

The positive solution for the given equation is 7 .

In the question ,

it is given that ,

when a number 14 is subtracted from the square of number ,

then the result is 5 times the number .

let that number be "x" .

These triangles can be proven congruent by using ASA RULE.

What is congruent triangles and its rules ?

When two triangles are congruent, their three sides and their three angles match precisely.

If there is a turn or a flip, the equal sides and angles might not be in the same place, but they are still present.

ASA rule stands for Angle-Side-Angle rule which means two angles and a side of both triangles are equal.

Main Body:

In ΔTUV and ΔTWV

VT =VT                 ----(1)

∠VTU=∠TVW      -----(2)

As TUVW is a parallelogram

so, ∠T = ∠U
