A car is worth $300

Step-by-step explanation:

A board game allows players to trade and sell game pieces of equal value

We need to find how much the car is worth

Assume that the car is worth $x and the house is worth $y

∵ Player 1 traded three cars plus $100 for a house

∴ 3 x + 100 = y

- Subtract 100 from both sides

∴ 3 x = y - 100

- Subtract y from both sides

∴ 3 x - y = - 100 ⇒ (1)

∵ Player 2 sold two houses and a car for $2300

∴ x + 2 y = 2300 ⇒ (2)

Now we have system of equation to solve it

Multiply equation (1) by 2 to eliminate y

∵ 6 x - 2 y = - 200 ⇒ (3)

- Add equations (2) and (3)

∴ 7 x = 2100

- Divide both sides by 7

∴ x = 300

A car is worth $300

Option C: y = 80x is the right answer

Step-by-step explanation:

Varying directly means that the increase/decrease in one quantity will cause increase/decrease in other quantity.

If y varies directly with x it is given by::

y ∝ x

When the proportionality symbol is removed, a proportionality constant is introduced

y = kx

If x = 1/2 and y = 40

then

[tex]40 = k * \frac{1}{2}\\k = 40*2\\k = 80[/tex]

Putting the value of k, we get

y = 80x

Hence,

Option C: y = 80x is the right answer

Answer:

MOP = DAB

Step-by-step explanation:

the sides have to be matched up as well. the side with only one dash (MO) has to correspond with the side with one dash from the other triangle (DA). Thus, the letters in the sequence (MOP) have to match up in the same order (DAB)

The correct congruency statement with regards to the congruence of the triangles is the fourth statement

The details of the steps by which the congruence statement can be found can be presented as follows;

The marks on the segment indicates;

PO is congruent to BA

MO is congruent to DA

PM is congruent to BD

Therefore, the triangle MOP is congruent to the triangle DAB

The order in which the markings on the triangles are located can also be used to find the correct congruence statement

The name of the triangle MOP indicates that the vertice of the triangle between the segment with three marklings, III, and the segment with one marking, I, is considered first, which is the vertice M and D on each triangle

The next mentioned vertice is the vertice between the segment with one marking and the segment with two markings, which is the vertice O and A on each triangle

The third considered vertice is the third vertice on both triangles, which corresponds to the vertice P and B on each triangle

The congruency statement is therefore ΔMOP ≅ ΔDAB

Answer:

The sell price of the truck rental after applying the coupon of 20 % is       $ 120  .

Step-by-step explanation:

Given as :

The regular rented price for the truck = $ 150

The discount as off coupon = 20 %

Let The sell price for truck after discount = x

So , Discount % = [tex]\dfrac{\textrm market price - \textrm Selling price}{\textrm market price}[/tex]

Or, 20 % = [tex]\dfrac{\textrm 150 - \textrm x}{\textrm 150}[/tex]

Or, [tex]\dfrac{x}{150}[/tex] = 1 -  [tex]\dfrac{20}{100}[/tex]

Or,  [tex]\dfrac{x}{150}[/tex] = [tex]\dfrac{100 - 20}{100}[/tex]

or,  [tex]\dfrac{x}{150}[/tex] = [tex]\dfrac{80}{100}[/tex]

∴ x = [tex]\frac{80\times 150}{100}[/tex]

I.e x = 8 × 15

Or, x = 120

Hence the sell price of the truck rental after applying the coupon of 20 % is $ 120  . Answer

Answer:

the % is 80% and the price $120

Answer:

Biker will catch the cyclist after 2 hr and 40 min.

Step-by-step explanation:

Given:

Speed of Bicyclist = 20 km/h

Travelling time = 4 hrs

∴ Distance = Speed × Time = [tex]20\times4=80 \ km[/tex]

Also he rest for 1 hr.

So we can say that, after 5 hrs Bicyclist is 80 km ahead when the biker Started.

Now Biker rate is given 50 km/h

And Bicyclist rate is 20 km/h

So, for each hour, biker advances 50 - 20 = 30 kilometers

now bicyclist distance is 80 km

and biker advances 30 per hour.

Therefore to catch up bicyclist at 80 km i.e time taken to reach 80 km with 30 km rate per hour.

Time = [tex]\frac{80}{30}=2 \frac{2}{3} h[/tex]

Hence, Biker will catch the cyclist after 2 hr and 40 min.

Li incorrectly added 64 and 17 to get 71, but the correct sum is 81 pages. This mistake was likely due to adding the tens place incorrectly.

Li made a mistake in her addition. When adding 64 and 17, she erroneously stated that the sum was 71 pages. To clarify what Li did wrong, we can simply add the two numbers together properly.

Start by adding the ones place: 4 (from 64) + 7 (from 17) equals 11. Write down 1 and carry over the 1 to the tens place.

Next, add the tens place: 6 (from 64) + 1 (from 17) + 1 (carried over) equals 8.

Combine the numbers in the tens and ones place to get 81.

Therefore, the correct sum of 64 and 17 is 81 pages. This is how many pages Li read in all.

Final answer:

To find the probability that the product of two standard dice is prime or ends in a 5, we need to count the favorable outcomes and divide it by the total number of possible outcomes. The probability is 1/4 or 0.25.

Explanation:

To find the probability that the product of two standard dice is prime or ends in a 5, we need to count the favorable outcomes and divide it by the total number of possible outcomes.

To have a prime product, the possible combinations are: (2,2), (2,3), (2,5), (3,2), (3,3), (3,5), (5,2), (5,3), (5,5)

To have a product that ends in 5, the possible combinations are: (1,5), (2,5), (3,5), (4,5), (5,5), (6,5).

The total number of favorable outcomes is 9.

When two dice are rolled, there are 36 total possible outcomes (6 possible outcomes for the first die multiplied by 6 possible outcomes for the second die).

Therefore, the probability that the product is prime or ends in a 5 is 9/36, which simplifies to 1/4 or 0.25.

y=-\frac{11}{13}x+\frac{8}{13}

Step-by-step explanation:

Answer:

y = -(11/13)x + (8/13)  

Step-by-step explanation:

recall slope intercept form of a linear equation takes the general form:

y = mx + b

In this case, simply rearrange the given equation such that it looks like the general equation above.

11x+13y=8  (subtract 11x from both sides)

13y = -11x + 8  (divide both sides by 13)

y = -(11/13)x + (8/13)    (answer)

Answer:

The value of angle of elevation is 44.4°  .

Step-by-step explanation:

Given as :

The measure of the rope of hot air balloon = 100 m

The height of balloon above the ground = 70 m

Let The angle of elevation = Ф

Now, According to question

Sin angle = [tex]\dfrac{\textrm Perpendicular}{\textrm Hypotenuse}[/tex]

Or, SinФ =  [tex]\dfrac{\textrm Height of baoolon above ground}{\textrm measure of rope}[/tex]

Or, SinФ = [tex]\frac{70}{100}[/tex]

Or, SinФ = [tex]\frac{7}{10}[/tex]

∴ Ф = [tex]Sin^{-1}[/tex]([tex]\frac{7}{10}[/tex])

I.e Ф = 44.4°

Hence The value of angle of elevation is 44.4°  . Answer

Draw the situation.

Apply sinθ  [tex]= \frac{opposite}{hypotenuse}[/tex]

sinθ [tex]=\frac{70}{100}[/tex]

θ = [tex]sin^{-1}[/tex][tex](\frac{70}{100} )[/tex]

Step-by-step explanation:

The conditions state, being x, N, M positive integers:

[tex]x-64=N^2[/tex]         [1]

[tex]x+25=M^2[/tex]       [2]

Subtracting the [1] from [2]

[tex]89=M^2-N^2=(M-N)(M+N)[/tex]

Since 89 has no other prime factors except 1 and itself, we can write

[tex](M-N)(M+N)=(1)(89)[/tex]

[tex]M+N=89[/tex]

[tex]M-N=1[/tex]

This system of equations results in [tex]M=45, N=44[/tex]

Replacing in [1] or [2] results

[tex]x=2000[/tex]

Proof:

[tex]2000-64=1936 =44^2[/tex]

[tex]2000+25=2025=45^2[/tex]

4y=-6x+10

y=-6/4x+10/4

simplify

y=-3/2x+5/2

The equation 6x + 4y = 10 written in slope-intercept form is y = -3/2x + 5/2.

The equation Y = mx + b exists in the slope-intercept form of the equation of a straight line. In the equation y = mx + b, m exists the slope of the line and b exists the intercept.
