y=x-3

Step-by-step explanation:

Graph y=x-5 and the point (1,-2). You want your slope to be the same for the lines to be parallel. The slope in the given equation is 1/1. Type into a graphing calculator y=x- and pick a number greater than negative five since the point (1,-2) is above the given line. Guess and checking reveals -3 to be the correct answer. Therefore, your answer is y=x-3.

x=120

The value of x for the given expression will be equal to 120.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given expression is 0.25(x +4) -3 = 28.

Conver the value 0.25 into fractions,

0.25=1/4

Apply the mathematical operations to get the value of x below,

1(x+4)-12=112

x+4-12=112

x-8=112

x=120

Therefore, the value of x for the given expression will be equal to 120.

Zahra runs a 500-meter race at a constant speed. Which graph shows her distance from the finish line during the race?

Answers

Answer: The answer is the third figure. Attached the image.

Step-by-step explanation: Given that Zahra runs a 500-meter race at a constant speed. We are to select the correct graph from the four options that will show her distance from the finish line during the race.

We can see in graph 2, the distance covered by Zahra in metres increases at the same rate as the time increases in minutes.

But, since we are considering from the finish line, so option (#) will be right, because Zahra starts at 500 metres, decreases in the same manner as the increase of time and goes down to 0 on the positive X-axis.

Also,

Thus, the attached graph, which is the third option is the correct graph.

A motorboat travels 440 km in eight hours going upstream and 510 km in six hours going down stream what is the rate of the boat in Still water and what is the rate of the current

Answers

Answer:

Rate of boat in still water = 70 km/hr

Rate of current = 15 km/hr

Step-by-step explanation:

Let the speed of motorboat in still water = [tex]u\ km/hr[/tex]

Let the speed of current = [tex]v\ km/hr[/tex]

Equivalent Speed upstream = [tex](u-v)\ km/hr[/tex]

Equivalent Speed downstream = [tex](u+v)\ km/hr[/tex]

Distance traveled upstream = 440 km

Time taken upstream = 8 hours

Using the formula:

[tex]Speed = \dfrac{Distance}{Time}[/tex]

[tex]u-v = \dfrac{440}{8}\\\Rightarrow u -v=55 ..... (1)[/tex]

Distance traveled downstream = 510 km

Time taken downstream = 6 hours

[tex]u +v = \dfrac{510}{6}\\\Rightarrow u+v=85 ...... (2)[/tex]

Adding (1) and (2):

[tex]2u = 140\\\Rightarrow u = 70\ km/hr[/tex]

By equation (1):

[tex]v = 85-70\\\Rightarrow v =15\ km/hr[/tex]

Therefore, the answer is:

Rate of boat in still water = 70 km/hr

Rate of current = 15 km/hr

And question 2 is use your knowledge of central and inscribed angles to find M.

Answer:

∠ RQS = 138°

Step-by-step explanation:

Since PR and PS are tangents to the circle, then

∠ QRP = ∠ QSP = 90°

The sum of the interior angles of PRQS = 360°

Subtract the sum of the interior angles from 360° for ∠ RQS

∠ RQS = 360° - (90 + 90 + 42)° = 360° - 222° = 138°

Assume that you remove all of the hearts from a normal deck of cards. Now, with this new hearts-only deck, how many possible five-card hands can you draw? (A normal deck of cards has 52 cards, 4 suits, and numbers 2-10, Jack, Queen, King, Ace.)

a. 4,669,920
b. 311,875,200
c. 154,440
d. 6,497,400

Answers

Answer:

c

Step-by-step explanation:

The possible way to draw 5 cards hand from set of  hearts-only deck is  15,4440 .

What is permutation?

Permutations are different ways of arranging objects in a definite order. It can also be expressed as the rearrangement of items in a linear order of an already ordered set. The symbol [tex]P_{r} ^{n}[/tex] is used to denote the number of permutations of n distinct objects, taken r at a time.

Formula of permutation

[tex]P_{r} ^{n}[/tex] = [tex]\frac{(n!)}{(n-r)!}[/tex]

According to the question

Remove all of the hearts from a normal deck of cards.

i.e,

Total normal deck of cards = 52

On Removing hearts cards(n) = 13  

Now, with this new hearts-only deck, how many possible five-card hands can you draw .

Card to draw (r)= 5

Applying formula of  permutation

[tex]P_{r} ^{n}[/tex] = [tex]\frac{(n!)}{(n-r)!}[/tex]

n = 13

r = 5

Substituting the values

[tex]P_{r} ^{n}[/tex] = [tex]\frac{(13!)}{(13-5)!}[/tex]

[tex]P_{r} ^{n}[/tex] = [tex]\frac{(13*12*11*10*9*8!)}{(8)!}[/tex]

[tex]P_{r} ^{n}[/tex] = 15,4440

Hence, the possible way to draw 5 cards hand from set of  hearts-only deck is  15,4440 .
