Hi!

Option d. Sedimentary rock →melting →solidification → metamorphic rock is a process that cannot happen.

Please check the attached image for the diagram of rock cycle. In it, the sedimentary rocks melt to form magma and solidifies into igneous rocks, not metamorphic rocks

Answer:

Perimeter is 12mm, height is \(2\sqrt3\)mm in simplest radical form, and 3.5mm in approximate decimal form.

Step-by-step explanation:

The perimeter is easy; since it's an equilateral triangle, all sides are the same length of 4, so you can just do 3*4 (3 sides, 4mm each) to get a perimeter of 12.

For the height, you can see that it forms two right triangles, each with a given base of 2 and a hypotenuse of 4. We can apply the pythagorean theorem (\(a^2+b^2=c^2\)) here to find the missing leg length of the smaller right triangles, which is equal to the big triangle's height.

I've enclosed an attachment for that.

Hope this helps!

Answer

original speed X=10

Step-by-step explanation:

We know that Speed= distance/ time

Then

time =distance/speed

We were told the cyclist travels 40 km at a speed of x km/h.

Which means

Distance= 40km

speed =x km/h

Then time t =40/x

Again we we were told his speed was

reduced by 2 km/h

Then speed= (x-2)

But the Distance is still 40km

But we were told the difference in time is 1 hour

Time t=40/(x-2)

Then if we find the difference between the time t of the first condition and second condition we have

40/(x-2) - (40/x) =1

[40x-40(x-2)]/ x(x-2)= 1

80=x(x-2)

x^2-2x-80=0

This is a quadratic equation , if we solve using factorization we have

(x+8)(x-10)

x+8=0 or x-10= 0

X= -8 or 10

But we cannot have a negative value for speed then

X=10

Therefore, original speedX=10

Answer:

5.62

Step-by-step explanation:

5.62 is bigger than 5.5

5.62 is bigger by 0.12

You can prove this by subtracting 5.5 from 5.62

If you were to subtract 5.62 from 5.5 you'd end up with a negative number, so obviously 5.62 is bigger

Answer:

x=30

Step-by-step explanation:

firstly, Cross multiply

21 × x = 18 × 35

x = 630 ÷ 21

x=30

Hope it helps!

Mark as brainliest please!

Answer:

Step-by-step explanation:

Given proportion,

→ 21/35 = 18/x

Now we have to,

→ Find the required value of x.

Let's find the value of x,

→ 21/35 = 18/x

→ 21x = 18 × 35

→ 21x = 630

→ x = 630/21

→ [ x = 30 ]

Hence, the value of x is 30.

Answer:

120

Step-by-step explanation:

5x-5

Let x = 25

Substitute into the expression

5(25) - 5

Multiply

125 -5

Subtract 120

Answer:

120

Step-by-step explanation:

If X = 25

where you see X , you put 25 there

5X - 5

5(25) - 5

125 - 5

= 120

Answer:

i would say the answer is C) simple random sampling

Step-by-step explanation:

this is because an example of a simple random sample would be the names of 25 employees being chosen out of a hat from a company of 250 employees. In this case, the population is all 250 employees, and the sample is random because each employee has an equal chance of being chosen. This is similar to your question where it chooses 100 random people.

hope this helps ;)

Answer:

\(\frac{16}{27}\)

Step-by-step explanation:

From the table, we notice that the total number of students is:

\(3+10+8+6=27\)

Then, along the second column of the table, we notice that the number of students who do not have a brother is:

\(10+6=16\)

So, the probability that a randomly chosen student does not have a brother is:

\(\frac{\text{number of students who do not have a brother}}{\text{total number of students}}=\frac{16}{27}\)

Answer:

The Bravo is more expensive by $19 than the Inferno

Step-by-step explanation:

Inferno:

2,000+12,000=14,000

14,000+438=15,038

Bravo:

3,000+11,340=14,340

14,340+717=15,057

--

15,057-15,038=19

The Bravo is more expensive by $19 than the Inferno.

Answer:

m ≥ 1

Step-by-step explanation:

Step 1: Isolate the variable. (Add 3 to both sides.)

m - 3 + 3 = -2 + 3

m ≥ 1

Answer: m ≥ 1

Step-by-step explanation:

Set up the equation

Add three to both sides

-3 + 3 = 0

-2 + 3 = 1

m ≥ 1

 Short answer: How many digits are repeated? 2, exactly (1 and 5). So 2 digits, you have 99. If you have one digit repeated (like 0.3333...) then its 9. So, because of its 99. The answer is 15/99. Try to get what I mean.  Long answer: 0.151515151515.... x = 0.151515151515... 100x = 15.1515151515.....                         (to get this equation you multiply the above by 100) Based on the red above, use elimination. 99x = 15                    (solve for x) x = 15/99
