A hiker is 3.5 miles from her campsite when she begins to walk back to it. She hikes back toward the campsite at a constant rate of 2.1 miles per hour.
Which equation models the distance of the hiker from her campsite? (Let m represent her distance, in miles from the campsite and h represent the number of hours since she begin walking back.)
O m= 3.5+ 2.1h
Om= 3.5h - 2.1
O m = 3.5h + 2.1
m = 3.5 - 2.1h

Step-by-step explanation: You must multuply the number of tacos by the money for all of them then you compare them and see if the see if they payed the same rate!P.S i'm in class too!!

Answer: They did not pay the same rate

Step-by-step explanation:

If they were to pay the same price the unit rate would be 1.25 but instead Ryan paid 1.25 for each taco and Maria paid 1.6 for each taco, which means they did not pay the same rate.

Answer:

6/12 or 1/2

Step-by-step explanation:

Since 11/12 and 5/12 have the same denominator (12), I didn't need to worry about anything pertaining to it. And because I didn't need to do anything that had to do with the denominator (12), I just did 11-5 (6), and made it 6/12, which is equivalent to 1/2. Hope this helped!

Answer:6/12

Step-by-step explanation: Step 1

Since our denominators match, we can subtract the numerators.

11 − 5 = 6

So the answer is:

6

12

Answer:

12x - 2

Step-by-step explanation:

Step 1: Write expression

4(3x + 2) - 6

Step 2: Distribute 4

12x + 8 - 6

Step 3: Combine like terms

12x - 2

12y = 4x + 8

A = 12y -4x + 8

B = 8yx = 8

C = yx =8/8

=yx = 1

Answer:

Jesse will have $120.

Step-by-step explanation:

First you need to set up your equation. We know Jesse has $60 already and that he charges $15 per lawn. Your equation will look something like this:

15x+60=?

Then you plug in the 4 lawns he did:

15(4)+60=

Then you solve and get 120! :)

PS Parenthesis mean you are multiplying. Same thing as saying

15 x 4 + 60= 120

Answer:

[tex]a_{n}[/tex] = 6n - 4

Step-by-step explanation:

There is a common difference between consecutive terms in the sequence, that is

8 - 2 = 14 - 8 = 6

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 2 and d = 6 , thus

[tex]a_{n}[/tex] = 2 + 6(n - 1) = 2 + 6n - 6 = 6n - 4

Thus the formula representing the sequence is

[tex]a_{n}[/tex] = 6n - 4

Step (1)

[tex](6w - 7) + (3x + 8) = 142[/tex]

[tex]6w + 3x - 7 + 8 = 142[/tex]

[tex]6w + 3x + 1 = 142[/tex]

Subtract sides -1

[tex]6w + 3x + 1 - 1 = 142 - 1[/tex]

[tex]6w + 3x = 141[/tex]

Divided sides by 3

[tex] \frac{6}{3}w + \frac{3}{3}x = \frac{141}{3} \\ [/tex]

[tex]2w + x = 47[/tex]

I call above equation (( Ω ))

_________________________________

Step (2)

[tex]180 - 142 = 38[/tex]

We have :

[tex](6w - 7) + 38 = (10w - 9)[/tex]

[tex]6w - 7 + 38 = 10w - 9[/tex]

[tex]6w + 31 = 10w - 9[/tex]

Subtract sides -6w

[tex]6w - 6w + 31 = 10w - 6w - 9 \\ [/tex]

[tex]31 = 4w - 9[/tex]

Plus sides 9

[tex]31 + 9 = 4w - 9 + 9[/tex]

[tex]40 = 4w[/tex]

Divided sides by 4

[tex] \frac{40}{4} = \frac{4}{4}w \\ [/tex]

[tex]w = 10[/tex]

_________________________________

Do u remember (( Ω )) ?

Of course u do...

[tex]2w + x = 47[/tex]

[tex]2(10) + x = 47[/tex]

[tex]20 + x = 47[/tex]

Subtract sides -20

[tex]20 - 20 + x = 47 - 20[/tex]

[tex]x = 47 - 20[/tex]

[tex]x = 27[/tex]

Answer:

I think that the answer is C) or the last one

I think it's the second one

[tex] - 9 {x}^{2} + 3x = 0 [/tex]

[tex]3x( - 3x + 1) = 0[/tex]

[tex]3 x = 0 \\ x = 0[/tex]

And

[tex] - 3x + 1 = 0 \\ - 3x = - 1 \\ x = \frac{ - 1}{ - 3} \\ x = \frac{1}{3} [/tex]

Answer:

0

Step-by-step explanation:

To solve this without L'Hopital's rule, you need to use this identity:

lim(x→0) (sin x / x) = 1

lim(x→0) (sin²x / x)

lim(x→0) (sin x / x) (sin x)

lim(x→0) (sin x / x) · lim(x→0) (sin x)

1 · 0

0

Alternatively, since plugging in x=0 gets 0/0, we can use L'Hopital's rule.  Replace the numerator and denominator with their derivatives.

lim(x→0) (sin²x / x)

lim(x→0) (2 sin x cos x / 1)

0

Answer:

C

Step-by-step explanation:

Both AB and AC have the length of 8, meaning that they're congruent.

This means that we have an isosceles triangle.

Angle B and Angle C are equal and all angles in a triangles add up to 180 degrees so:

30 + 30 = 60

180 - 60 = 120

So C would be your answer.

Please let me know if I'm incorrect :)

Answer:

120°

Step-by-step explanation:

This is an Isosceles triangle and that means angle C = angle B

Since the sum of interior angles in a triangle is equal to 180° the measure of angle A is = 120°

Answer:

Step-by-step explanation:

a

The square root of 20 = 4.47 so a for sure.

But the root of 20 is also -4.48 so that means that 2 and 3 are added to the list

Now what to do about - 8

(- 8)^2 = 64

The square root of 64 = +/- 8

It's kind of slippery but it depends on how you see the problem. It is a bit ambiguous.

I would eliminate - 8 but your instructor may not. Argue that it should not be included, but don't take the argument on forever. Let it go.

a for sure.

b and c I think so.

-8 is iffy.

Answer:

Step-by-step explanation:

Answer:

x^2-2x-24

Step-by-step explanation:

Answer:

125

Step-by-step explanation:

Measure of d will be,

⇒ d = 125°

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

Here, r and s are two parallel lines

And, q is the Transversal

Here, Uppercase left angle is 125 degrees

And, The bottom right angle is d degrees

We know that the sum of supplementary angles is 180°

Hence, By the figure, we get;

125 + x = 180

x = 180 - 125

x = 55°

Also we know that

Alternate interior angles are formed by a transversal intersecting two parallel lines . They are located between the two parallel lines but on opposite sides of the transversal, creating two pairs of alternate interior angles. Alternate interior angles are congruent, meaning they have equal measure.

So, Measure of d will also be,

d = 125°

Or,

d = 180 - 55

   = 125°
