Answer:

At 15:15

Step-by-step explanation:

Given,

the 1st boy can run a lap in 15 minutes

the 2nd boy can run a lap in 25 minutes

the 3rd boy can run a lap in 10 minutes

Now if they start running at 12:45,they will meet after the time which will be equal to the L.C.M. of their time need to run a lap.

[tex]L.C.M.[/tex] of 15,25 & 10 = 150

So,they will pass each other after 150 minutes or 2 hours & 30 minutes.

If we add it with 12:45 we'll get 15:15 or 3:15 pm

Answer:

Step-by-step explanation:

  √24 = 2√6

  √48 = 4√3

Then the sum is ...

  √24 +√48 = 2√6 +4√3

Factoring out √3, we have ...

  = (2√2 +4)√3

Matching this to the form a√b, we have

  (2√2+4)√3   ⇒   a=2√2+4, b = 3

Step-by-step explanation:

Answer:

A)yes

B)yes

c)no

d)yes

e)yes

f)no

Part A

This is the same as saying 2(AB+BC). A more written out version is AB+BC+CD+DA, though it's not needed since the opposite sides are congruent (AB = CD and BC = DA)

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

Part B

The diagonals of any parallelogram bisect each other. They cut each other in half.

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

Part C

The adjacent sides of a parallelogram aren't always equal in length. It only happens when we have a rhombus.

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

Part D

The angles mentioned are alternate interior angles. They are congruent due to AD and BC being parallel.

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

Part E

We can use the SSS or SAS congruence theorem to prove these triangles are congruent.

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

Part F

These are adjacent angles that aren't always the same measure. Diagonal AC does not bisect angle DAB. This only happens if we had a rhombus.

Answer:

The integers are -58, -57, -56.

Step-by-step explanation:

The difference between two consecutive integers is 1.

If you let the smallest of the three consecutive integers equal x, then the next greater one is x + 1, and the greatest of the three is x + 2.

Integers: x, x + 1, x + 2

The sum of the first and third is: x + x + 2

3 times the sum of the first and third is: 3(x + x + 2)

That product equals -342.

3(x + x + 2) = -342

3(2x + 2) = -342

Divide both sides by 3.

2x + 2 = -114

Subtract 2 from both sides.

2x = -116

Divide both sides by 2.

x = -58

x + 1 = -57

x + 2 = -56

The integers are -58, -57, -56.

Answer:

the opposite of 9

Step-by-step explanation:

the absolute value of nagative 9, is positive 9.

the absolute value of postive 9, is postive 9.

the distance between 0 and nagative 9 on a line would be a count of postive 9.

the opposite of postive 9 is negative 9 (the only one with a diffrent outcome)

Answer:

35

Step-by-step explanation:

Order of Operations: BPEMDAS

Step 1: Write out expression

3 + 2(13 - 17)²

Step 2: Parenthesis subtraction

3 + 2(-4)²

Step 3: Exponent

3 + 2(16)

Step 4: Parenthesis multiplication

3 + 32

Step 5: Add

35

Answer:

Equal

Step-by-step explanation:

The absolute value of any number is the same as the value between the lines, but instead, it is positive. The lines (|x|)represent the amount of units/numbers |-5| and |-(-5)| is away from 0. They are both 5 numbers away from it, so it is equal.

Answer: Yes it is equal.

Step-by-step explanation:

when a number is an absolute, always assume it is possitive number.

Example: l-2l = 2 or l2l = 2

i hope that made sense.

Step-by-step explanation:

Precision means that a measurement using a particular tool or implement produces similar results every single time it is used. For example, if you step on a scale five times in a row, a precise scale would give you the same weight each time. In math and science, calculating precision is essential to determine if your tools and measurements work well enough to get good data. You can report precision of any data set using the range of values, the average deviation, or the standard deviation.

Answer:

C. Circle X, circle Z, circle Y

Step-by-step explanation:

Given

Circles X, Y and Z

Required

Order from greatest to highest

First, we need to simplify the given areas;

For Circle X

[tex]A = 9\pi[/tex]

Take [tex]\pi[/tex] as 3.14

[tex]A = 9 * 3.14[/tex]

[tex]A = 28.26[/tex]

For Circle Y

[tex]A = \frac{\sqrt3}{2}[/tex]

This gives

[tex]A = \frac{1.732}{2}[/tex]

[tex]A = 0.866[/tex]

For Circle Z

[tex]A = 27.5[/tex]

By comparing the above areas;

X has the largest area; followed by Z and then Y

Hence,

option C answers the question

Answer:

Just say, "No, 7 to 4 is not the same as 4 to 7. I don't know why, but I just know because you taught me it wasn't."

Step-by-step explanation:

It worked for me lol

Answer:

4 to 7 is pretty much 4 divided by 7 which = 4/7 and 7/4 is 1 3/4. which is obviously greater. So they both equal different answers.

Answer: Choice D.  [tex]6.44 \times 10^{-4}[/tex]

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

Work Shown:

We multiply the coefficients 9.2 and 7 to get 64.4, which is the same as 6.44*10^1 in scientific notation. When multiplying exponential expressions with the same base, we add the exponents

This is what the steps could look like

[tex]\left(9.2 \times 10^{-9}\right)\times\left(7 \times 10^{4}\right)\\\\\left(9.2\times7\right)\times\left(10^{-9} \times 10^{4}\right)\\\\\left(64.4\right)\times\left(10^{-9+4}\right)\\\\\left(6.44\times 10^{1}\right)\times\left(10^{-5}\right)\\\\6.44\times\left(10^{1}\times 10^{-5}\right)\\\\6.44\times\left(10^{1+(-5)}\right)\\\\6.44\times 10^{-4}\\\\[/tex]

The final result is in scientific notation as the coefficient c is restricted such that [tex]0 \le c < 10[/tex]
