Answer:

46?

Step-by-step explanation:

23*2=46

Answer:

37.31 cm

Step-by-step explanation:

∡ AB = 180 - 148 = 32° = ∡ DE

∡ CD = 360 - ∡ AE - ∡ AB - ∡ BC - ∡ DE = 360 - 148 - 32 - 87 - 32 =61°

∡ CE = 61 + 32 = 93°

arc length = 2[tex]\pi[/tex]r [tex]\frac{angle}{360}[/tex] = 2×3.14×23×[tex]\frac{93}{360}\\[/tex] = 37.31 cm

Step-by-step explanation:

Use the slope formula

Taking two points on the line:

(0,3) and (-5,0)

3-0/0+5

You will get: 3/5 as your slope

The y-intercept is (0,3)

Therefore:

y = 3/5x + 3

Answer:

B (0, -2)

Step-by-step explanation:

Since the line intercepts at -2 on the y-axis, -2 is the y-intercept.

Answer:

  20 hours

Step-by-step explanation:

The volume of water when the pool is 80% full can be found using the proportion ...

  2250/75% = v/80%

  v = (80/75)(2250) = 2400 . . . cubic meters

Emptying at the rate of 120 m³/h will take ...

  time = volume/rate

  time = (2400 m³)/(120 m³/h) = 20 h

It will take 20 hours to empty the pool from 80% full.

Answer:

no

Step-by-step explanation:

the x values repeat itself

The given relation is not a function.

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

Given a table of x and y values.

We have to determine the relation is a function or not.

By the definition of functions, a relation is a function if an input value does not map to two output values.

That is, an x value will not map to two y values.

From the table,

x = 1 maps to two y values -2 and -3.

This is not possible for functions.

So this is not a function.

Hence the relation is not a function.

Answer:

y = 6

x = 4

How to find 'x':

4x - y = 10

y = 2x - 2

First, you need to substitute the 'y' into the first equation.

4x - 2x - 2 = 10

Next, add the x's together. As it's a negative 2x then take away 2 from 4.

2x - 2 = 10

3. Now that it's a normal equation, you can add 2 to cancel out the -2

2x = 8

4. Then divide the 8 by 2 and you will get the answer to x which is 4

x = 4

How to find 'y':

1. Now that we have found out 'x'. Let's go back to y = 2x -2 and use the x to found the answer out. It should be something like this:

y = 2x - 2

y = 2(4) - 2

y = 8 - 2

8 - 2 = 6

y = 6

Conclusion:

So the answer would be:

y = 6

x = 4

You can see if it's correct by putting y into 4x - y = 10.:

4x - 2 = 10

4(4) - 6 = 10

16 - 6 = 10

So that means that y and x are the correct answer.

Answer:

  y-intercept: (0, 5/2)

  x-intercept: (5/3, 0)

Step-by-step explanation:

The y-intercept is found by setting x=0 and dividing by the coefficient of y.

  0 +2y = 5

  y = 5/2

The x-intercept is found by setting y=0 and dividing by the coefficient of x.

  3x +0 = 5

  x = 5/3

The intercepts are ...

  y-intercept: (0, 5/2)

  x-intercept: (5/3, 0)

Answer:

430 > 33.73x + 27      ---->         x < 11

Step-by-step explanation:

The inequality describes the total amount that can be spent for a whole number of days. To solve for the number of days, solve for x (x<11.95). Because she can't rent for only a part of a day, and because she can't spend more than $430, the inequality becomes x<11.

Answer:

Step-by-step explanation:

33.73x + 27 <= 430

0.06 is for every mile. She plans to drive 450 miles. So 0.06 times 450. Which is 27.

Then your have the 33.73 for each day for the rent of the car. We don't know how many days so we'll just put x.

Answer:

11.59 hours  {Basically 12 hours]

Step-by-step explanation:

Sarah's coin rate is 23 coins/8 minutes, or 2.875 coins/minute

Rate * Time(X) = Coins

(2.875 coins/min)*(X) = 2000 coins

X = (2000 coins)/(2.875 coins/min)

X =  695.65 minutes

(695.65 minutes)*(1 hour/60minutes) = 11.59 hours

Answer:

N=3

Step-by-step explanation:

use cross multiplication to find 28N=84 and then divide both sides by 28 to get N=3

Answer:

N = 3

Step-by-step explanation:

Given Δ ABC is similar to Δ DEF , then the ratios of corresponding sides are in proportion, that is

[tex]\frac{AB}{DE}[/tex] = [tex]\frac{BC}{EF}[/tex] , substitute values

[tex]\frac{21}{N}[/tex] = [tex]\frac{28}{4}[/tex] = 7 ( multiply both sides by N to clear the fraction )

21 = 7N ( divide both sides by 7 )

3 = N

Answer:

negative numbers don't have square roots. a square is either positive or 0, so your questions answer doesn't exist. if you want positive 7 though, 5.291502... etc

Answer:

Well to solve this I’m gonna use substitution

So

2x-3y=-14

5x+9y=14

I‘m gonna isolate ”x” on the first equation

So it’ll be

2x-3y=-14

2x=-14+3y

x=-7+1.5y

X is -7+1.5y

Now you can subsitute into other equations to find what Y is worth

So lets use the second equation

5(-1+1.5y) + 9y = 14

Now solve for y which is -2

If you subsitute Y back in an equation you’d get -4 for x

So y = -2

and X= -4

Answer:

y= 0.75x + -0.50

A or B is what im guessing

An object at point A moving to point B is displaced in the direction of

r = (5i - 2j) m - (2i + j) m = (3i - 3j) m

(I assume distance is measured in meters)

If the force is F = (10 N) (3i - 4j), then the work performed by F in the direction of r is

F • r = (10 N) (3i - 4j) • (3i - 3j) m = (10 N) (9 + 12) m = 210 J
