Answer:

7 and 8: these are both proportional relationships because they grow at a constant rate of change

9: for every 40 miles that the car travels, it uses 2 gallons of gas.

10:  y= 20x

11: the graph would be steeper and have a greater rate of change. This car would be able to go farther on less fuel.

Answer:

  c) 1.8 miles

Step-by-step explanation:

Assuming Kayla walks at a constant speed, we have ...

  miles/minutes = 3.2/45 = x/25

  x = 25(3.2/45) = 1.777... ≈ 1.8 . . . . miles

Kayla walks about 1.8 miles in 25 minutes.

Answer:

C) 1.8 miles

Step-by-step explanation:

Let's use the elimination process for this one. 2.4 and 3.2 are way too large. 0.5 is too small, so the answer is c

The probability that none of the coupons reveal a discount of 50% is 0.28.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

We have,

Binomial distribution states that,

P = [tex]^nC_kp^k q^{n - k}[/tex]

Now,

30% of the coupons will reveal a discount of 50%.

This means,

p = 30% = 0.3

q = 70% = 0.7

Now,

Select 10 coupons:

n = 10

Now,

The probability that none of the coupons reveal a discount of 50%.

[ None means k = 0 ]

So,

P(k) = [tex]^nC_kp^k q^{n - k}[/tex]

P(0) = [tex]^{10}C_0(0.3)^0 (0.7)^{10 - 0}[/tex]

P(0) = 10 x 1 x 0.028

P(0) = 0.28

Thus,

The probability that none of the coupons reveal a discount of 50% is 0.28.

okay now let's find the number of students who chose running

122 - 46 - 18 = 58

now, I'll find the probability

Step-by-step explanation:

Answer:

x=20

Step-by-step explanation:

2.5x=50

[tex]\frac{2.5}{2.5} =\frac{50}{2.5}[/tex]

x = 20

Have a great day!!!!

PumpkinSpice1

the solution to the equation 2.5x = 50 is x = 20.

To solve the equation 2.5x = 50 and find the value of x, we can divide both sides of the equation by 2.5. By doing so, we eliminate the coefficient of x and isolate the variable.

Dividing both sides by 2.5, we have:

(2.5x) / 2.5 = 50 / 2.5

Simplifying, we get:

x = 20

Therefore, the solution to the equation 2.5x = 50 is x = 20. When we substitute x with 20 in the equation, we have 2.5 * 20, which indeed equals 50. Thus, x = 20 satisfies the equation, and it represents the value that makes the equation true.

Answer:

Nick gets 93 pounds

Step-by-step explanation:

June gets X

Nick gets 3X

Angad gets twice as much as Nick, so 2*(3X) = 6X

X+3X+6X=310

X= 31

We check

June gets 31 pounds

Nick gets 93 pounds

Angad gets 93x2 = 186 pounds

31+93+186 = 310. It's correct!

Answer:

64.8°

Step-by-step explanation:

A

Please see attached a rough sketch for your reference

Step one:

Given data

the distance you are standing from the building represent the adjacent =400ft

and the height of the building represents the opposite= 850ft

Step two:

Required is the angle of elevation

applying SOH CAH TOA

Tan ∅= opp/adj

Tan ∅= 850/400

Tan ∅=2.125

∅=Tan-1(2.125)

∅=64.8°

The angle of elevation 64.8°

You can use the fact that buildings are usually standing perpendicular to the ground and ground for smaller distance acts as if its a straight plane.

The measurement of angle of elevation is [tex]64.798^\circ[/tex]

What you see something higher than your eye level height, you need to see up, you elevate your head to see that thing. The angle from the straight horizontal level of eye to the current elevated level is measured and named as angle of elevation.

Similarly, there is angle of depression when the observer looks down.

See the figure attached below to understand the symbols used in calculations.

Since the building is 850 ft tall, we can assume that our height is almost 0 in comparison to this building (the angle deduced then will be approximately equal to the real angle).

Let you're standing on point O

Let the building's base is point A.

Let the top of the building is tagged as point E.

Then we have:

Length of OA = 400 ft.

Length of AE = 850 ft.

To find: angle AOE.

[tex]tan(\angle AOE) = \dfrac{AE}{OA} = \dfrac{850}{400} = 2.125\\\\ m\angle AOE = arctan(2.125) = 64.798^\circ \text{\: (from calculator)}[/tex]

Thus, the measurement of angle of elevation is [tex]64.798^\circ[/tex]

Answer: angle V = 41 degrees  (choice B)

======================================================

Explanation:

We're told that RS = ST = RT. This means triangle RST has all three sides equal to one another. This triangle is equilateral. Each interior angle is 60 degrees. This is because each angle is y, and y+y+y = 180.

Since each angle of triangle RST is 60 degrees, this means angle STR is 60 degrees.

Let z be the measure of angle UTV. Note how

(angleSTR)+(angleUTV) = 180

60+z = 180

z = 180-60

z = 120

Making angle UTV to be 120 degrees

------------------------------------

Now we can focus on triangle UTV since we have expressions for each interior angle

Add up those angles, set the sum equal to 180, solve for x

U+T+V = 180

(4x-9)+(120)+(5x+6) = 180

9x+117 = 180

9x = 180-117

9x = 63

x = 63/9

x = 7

Use that x value to find the missing angle measures

angle U = 4x-9 = 4*7-9 = 28-9 = 19 degrees

angle V = 5x+6 = 5*7+6 = 35+6 = 41 degrees

Note how

U+T+V = 19+120+41 = 180

which helps confirm our answer.
