Step-by-step explanation:
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
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
Hope this helps!

Angle TVZ makes a linear pair with angle ZVW so the measure of angle TVZ plus the measure of angle ZVW=180 degrees. Angle ZVW is also a linear pair with angle RVW. Angle RVW is a vertical angle to angle TVZ. Use these relationships to determine the measure of angle TVZ.
Answer:
Step-by-step explanation:
2x +15 +2x +5 = 180
4x = 180 - 20
x = 160/4
x = 40
TVZ + 2x +5 =180
TVX +2(40) = 180 -5
TVX = 175 - 80
TVX = 95
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?
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 )
Given that ∠ ABD ≅∠ RQS and m DBC = 33, what is m ∠RQS?
Answer:
57°
Step-by-step explanation:
57°
∠ ABD =∠ RQS , ∠DBC = 33°
∠ ABD = 90° - 33° = 57°
∠ RQS = 57°

eats 54 nathan's hot dogs in 12 minutes. number of hot dog per minute rate of change
Answer:
4.5 hot dogs per minute
Step-by-step explanation:
rate of change=hot dog/minutes=54/12=4.5
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.
This can be simplified to 4.5 as the rate of change.
a train travels 24 miles in 30 minutes at this rate how many minutes will it take the train to travel 36 miles?
Answer:
45 minutes
Step-by-step explanation:
1/2 of 24 is 12
24 + 12 is 36
1/2 of 30 is 15
30 + 15 is 45
Answer:
The answer is 42
Step-by-step explanation:
36 miles minus 24 mil3s equals 12 so you plus 30 minutes 12 eq 42 minute.

help i need to know what k is
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.

Answer:
y axis: (0, 12)
x axis: (18, 0)
Quadrant I: (4.5, 10.6)
Quadrant II: (-15, 21)
Quadrant III: (-3/4, -4 1/9)
Quadrant IV: (3, -7)
Step-by-step explanation:
Integers used for each Quadrant.
Quadrant one: x axis = positive, y axis = positive
Quadrant two: x axis = negative, y axis = positive
Quadrant three: x axis = negative, y axis = negative
Quadrant four: x axis = positive, y axis = negative
(0,12) = goes to the y axis
(3,-7) = goes to quadrant 4
(-15,21) = goes to quadrant 2
(18,0) = goes to the x axis
(4.5,10.6) = goes to quadrant 1
(-3/4, -4 1/9) = goes to quadrant 3

Answer:
Interestingly, there would be 100 of each the half dollars and the quarters.
Step-by-step explanation:
100 quarters, each quarter being 1/4 of a dollar, 100x.25= 25. And 100 half dollars, 1/2 of a dollar, 100x.50=50

A car has a speed of 25 m/s. What is its speed in km/hr? (1 km = 1000 m) (1
hr = 3600 s)
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.
so if each equation for x x / a - 5 equals B

The price of a video game is marked up by 35%. What is the new price of the game before the markup was 40$? (help <3)
Answer:
Solution :
Selling price (S.P) = (100 + m)% ⋅ C.P
Here,
M = 35, C.P =40$
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:
$54Step-by-step explanation:
Given:
Initial price = $40Mark up = 35%Find the mark up price:
$40 + 35% = $40 + 0.35*$40 = $40 + $14 =$54A map of Pennsylvania has a scale of ¾ inch to 25 miles. If Pittsburgh and Philadelphia are 9 inches apart on the map, how many miles apart are the two cities?

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
