Answer:

The answer is B(s*12=96)

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: 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]

Answer:

10). 5x + (7x + 6) = 90

11). x = 7

Step-by-step explanation:

From the picture attached,

Sum of given angles measures 90°

Measures of the angles are (5x)° and (7x + 6)°

Therefore, equation to determine the values of x will be,

5x + (7x + 6) = 90

By combining similar terms of the equation,

12x + 6 = 90

12x = 90 - 6

12x = 84

x = [tex]\frac{84}{12}[/tex]

x = 7

Therefore, by solving the equation value of x will be 7.

Step-by-step explanation:

Is the 2 an exponent? if so:

Plug 9 into S

so rewrite as 4(9)^2+10=1306

If not: then 4(9)(2)+10= 82

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.

Answer:

THE SET OF ALL POINTS IN A PLANE THAT ARE THE SAME DISTANCE AWAY FROM SOME GIVEN POINT , WHICH WE CALL THE CENTER.

Step-by-step explanation:

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:

[tex]1.0736 \times 10^{19}[/tex] ways

Step-by-step explanation:

Given that:

Mikayla bought a bag of 84 pieces of candy.

she wants to divide them evenly and place them into bag such that they are not more than 20 bags.

Therefore, the number of possible ways she can do that is ;

[tex]^{84}C__{20}[/tex]

= [tex]\dfrac{84!}{20!(84-20)!}[/tex]

= [tex]\dfrac{84!}{20!(64)!}[/tex]

[tex]= 1.0736 \times 10^{19}[/tex] ways

The possible ways she can fill the bag = [tex]1.0736 \times 10^{19}[/tex] ways

Answer:

x = 3 or x = -2

Step-by-step explanation:

Solve for x over the real numbers:

(x + 2) (x - 3) = 0

Hint: | Find the roots of each term in the product separately.

Split into two equations:

x - 3 = 0 or x + 2 = 0

Hint: | Look at the first equation: Solve for x.

Add 3 to both sides:

x = 3 or x + 2 = 0

Hint: | Look at the second equation: Solve for x.

Subtract 2 from both sides:

Answer: x = 3 or x = -2

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 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:

Vertex: (-3, -1)

Domain: All real numbers or (-∞, ∞)

Range: (-∞, -1]

Step-by-step explanation:

Quadratic Function: f(x) = a(bx - h)² + k

(h, k) is vertex

Step 1: Find vertex

f(x) = -2(x + 3)² - 1

h = -3

k = 1

Vertex = (-3, 1)

Step 2: Graph

When we graph, we should see our domain and range.

Domain is all x-values that can be inputted into the function.

Range is all y-values that can be outputted from the function.

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

Answer : The measure of ∠WRS is 25°.

Step-by-step explanation :

As we know that vertically opposite angles are always equal.

In the given figure,

∠VRT = ∠WRS = (5x)°          (Vertically opposite angles)

And we know that the sum of all angle in a straight line is equal to 180°.

So,

∠TSR + ∠WRS = 180°

Given: ∠TSR = (25x + 30)°

∠TSR + ∠WRS = 180°

(25x + 30)° + (5x)° = 180°

30x + 30° = 180°

30x = 180° - 30°

30x = 150°

x = 5°

∠WRS = (5x)° = (5 × 5)°  = 25°  

Therefore, the measure of ∠WRS is 25°.

Answer: 25°

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.
