The vertices of quadrilateral MNPQ are M(−3,−2),N(−1,4),P(2,4), and Q(4,−2). Translate quadrilateral MNPQ using the vector ⟨3,−4⟩.


The vertices of M′N′P′Q′ after the translation are?

Answers

Answer:

see explanation

Step-by-step explanation:

A translation using the vector < 3, - 4 > , means

Add 3 to the x- coordinate and subtract 4 from the y- coordinate, so

M (- 3, - 2 ) → M' (- 3 + 3, - 2 - 4 ) → M' (0, - 6 )

N (- 1, 4 ) → N' (- 1 + 3, 4 - 4 ) → N' (2, 0 )

P (2, 4 ) → P' (2 + 3, 4 - 4 ) → P' (5, 0 )

Q (4, - 2 ) → Q' (4 + 3, - 2 - 4 ) → (7, - 6 )

Answer:

41. s = semiperimeter

s = (a + b + c) /2

s = (120+170+250) /2

s = 270m

d is the correct option.

42. b is the correct option.

43. P = a + b + c

P = 120+170+250

P = 540m

a is the correct option.

9x-3x +17= 3x-3x -5

6x+ 17+ 5= -5+5

6x/6= -22/6

x= -3.6

3x-5= 6y+1 ( vertical angles)

The price of a video game is marked up by 35%. What is the new price of the game before the markup was 40$? (help <3)

Answers

Answer:

Solution :

Selling price (S.P) = (100 + m)% ⋅ C.P

Here,

M = 35, C.P =40$

Then,

S.P = (100 + 35)% ⋅ 40

S.P = 135% ⋅ 40

S.P = 1.35 ⋅ 40

S.P = 54

So, the selling price is $54.

Answer:

$54

Step-by-step explanation:

Given:

Initial price = $40Mark up = 35%

Find the mark up price:

$40 + 35% = $40 + 0.35*$40 = $40 + $14 =$54

help i need to know what k is

Answers

Answer:

k = 5

Step-by-step explanation:

The formula for coefficient of proportionality is y = kx.

In the given problem, the Area of a rectangle corresponds to "y" in the constant of proportionality formula, and "x" is still the same. Since the formula for the area of a rectangle is: A = L × W, then:

A = y

L = k

W = x

y = kx is the same as A = LW or A =  L × W

Thus, we're looking for the value for k, which corresponds to the length (L) (which has a constant value).

Below are the calculations for the missing values in the table:

We'll start with x = 0.14, and A = 0.7 since we're given the values for them. We could plug these values into the formula for the Area of a rectangle to find the constant value of the length (L):

A = L * W

0.7 = L * 0.14

Divide both sides by 0.14 to isolate L:

0.7/0.14 = (L * 0.14)/0.14

5 = L  ←← Keep in mind, this is the coefficient of proportionality.

x = 3.1:

A = L * W

A = 5 * 3.1

A = 15.5

x = 2.5:

A = 5 * 2.5

A = 12.5

x = 1.2:

A = 5 * 1.2

A = 6

x = 0.9:

A = 5 * 0.9

A = 4.5

Next, we're given the values for the Area, but we're missing the values for x. However, we already have the value for L = 5. We could still follow the same process by plugging in the values into the formula:

A = 0.3:

A = L * W

0.3 = 5 * W  

Divide both sides by 5 to solve for W:

[tex]\frac{0.3}{5} = \frac{5 * W}{5}[/tex]

0.06 = W

A = 0.1:

A = L * W

0.1 = 5 * W  

Divide both sides by 5 to solve for W:

[tex]\frac{0.1}{5} = \frac{5 * W}{5}[/tex]

0.02 = W

Therefore, k = 5.

Two cards are randomly drawn. (5 blue cards and 3 yellow cards) What is the probability of drawing two blue cards if the fist card is not included in the second draw? simlify your answer completely

Answers

Answer:

5/14

Step-by-step explanation:

The probability of drawing a particular coloured card is the number of cards that are that colour, divided by the total number of cards:

The probability of drawing a blue card on your first draw would be 5 out of (5 + 3) = 5/8

The next draw would be the same principle, but the denominator (bottom number of the fraction) would be 1 less, because you have just taken out 1 card on your first draw:

The probability of drawing a blue card on your second draw (after drawing a blue card first) would be 4 (since you have already taken one) out of (8 - 1) = 4 / 7

To find the probability of both these steps combined, you multiply the two fractions together:

5/8 x 4/7 = 20/56

The question asks you to simplify, which means that the final answer is 5/14

A car has a speed of 25 m/s. What is its speed in km/hr? (1 km = 1000 m) (1
hr = 3600 s)

Answers

Step-by-step explanation:

the car went 25 meters in 1 second.

that creates this ratio 25 m/s or

formally fully correct 25/1 m/s.

to get the speed in km/h we need to bring the denominator of that ratio from 1 second to 1 hour.

we do that by multiplying it by 3600, as there are 3600 second in 1 hour.

to keep the overall value of the ratio we need to multiply also the numerator with the same factor.

so,

25/1 × 3600/3600 = (25×3600)/3600 =

= 90000 meters /1 hour

how many km (kilometers) are 90000 meters ?

1 km = 1000 m

so,

90000 m = 90000/1000 km = 90 km

therefore, or full answer is

the car's speed was 90 km/h.

Step-by-step explanation:

Answer:

4.5 Hotdogs per Minute

Step-by-step explanation:

Rate of change is found by dividing the total amount of an object, in this case the hotdogs, by the amount of time.

We know that Nathan has 54 hotdogs and that he eats them in 12 minutes.

Therefore: [tex]\frac{54}{12}[/tex] is the rate of change.

Rotting nets, hung out to dry in the last century, decorated their weathered walls. Their broken faces spun stories in our minds. The fishermen who, tanned and wrinkled from sun and salt, hauled their nets full of splashing mullet in to cheers from the waiting crowds.
