Answer:

8

Step-by-step explanation:

1/2 goes to 3/4.. 5/8 goes to 3/4 as well, and both of them together would be 1

Answer:

  MP = 38

Step-by-step explanation:

Each of the lengths MP, NP, OP is the radius of the incircle, so they are all congruent.

  3x +14 = 9x -34

  48 = 6x . . . . . . . . . . . . . . add 34-3x to both sides

  24 = 3x . . . . . . . . . . . . . . divide by 2 (we don't need x; we need 3x or 9x)

  NP = 3x +14 = 24 +14 = 38

  NP = OP = MP = 38

Answer:

Step-by-step explanation:

step 1. since we have a right triangle we can use trigonometry

step 2. <A: 5 is the opposite and 8 is the hypotenuse so we use sine

step 3. sinA = opp/hyp = 5/8

step 4. A = 38.68° using inverse sine on your calculator.

Answer:

y = 1/2x + 4

Step-by-step explanation:

If it's parallel, then the slope will remain the same.

To find the y-intercept, you have to plug the coordinates into the equation.

y = 1/2x + b

6 = 1/2 (4) + b

6 = 2 + b

4 = b

Answer:

Hanno moves faster than Simone.

Step-by-step explanation:

Simone: 25x100=2500m or 2.5km in 25x12=300 seconds or 5 minutes

Hanno- 2.5 km in 4minutes

So, Hanno moves 1 minute faster.

Answer:

Yes

Step-by-step explanation:

The idea is to use the formula for perpendicular gradients,

meaning m1 * m2 = -1

Since L2 passes through 2 points and to find gradient we just need 2 points,

we can use the 2 given points given

L2 gradient is (9 - (-7)) / (7 - (-1)) = 16/8 = 2

x + 2y = 4 rewrite as  y = -(0.5)x + 2

so our m1 is -0.5 and m2 is 2

-0.5 * 2 = -1  which was what we wanted to show.

L1 and L2 are perpendicular

Yes, Michael is correct.

Thew lines L1 and L2 are perpendicular.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.

Given:

The straight line L1 has equation x + 2y = 4.

y = -x/2 + 2.

The straight line L2 passes through the points (-1, -7) and (7, 9).

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

m = 16/8

m = 2

Slope of L1 = -1/2 and slope of L2 = 2.

The slope of the lines are negative reciprocal of each other.

That means, the lines are perpendicular.

Therefore, lines are perpendicular.

Answer:

Percent of change each year = 5%

Step-by-step explanation:

P.S - The exact question is -

Given - The number of carbon atoms in a fossil is given by the function,

             y (x)= [tex]5100(0.95)^{x}[/tex], where x represents the number of years since

             being discovered.

To find - What is the percent of change each year? Explain how you arrived

              at your answer

Proof -

Given that, the number of carbon atoms in a fossil is y(x) = [tex]5100(0.95)^{x}[/tex]

Initially, the number of fossils be

y(0) = [tex]5100(0.95)^{0}[/tex] = 5100

After 1 year, The number of fossils be

y(1) = [tex]5100(0.95)^{1}[/tex] = 5100(0.95) = 4845

Now,

Change in 1 year = y(0) - y(1) = 5100 - 4845 = 255

Now,

Percent of chance  = [tex]\frac{255}{5100}[/tex] × 100%

                                = 0.05 × 100%

                                = 5%

⇒Percent of chance = 5%

∴ we get

Percent of change each year = 5%

Answer:

Step-by-step explanation:

the arc of an inscribed angle is equal to 2 x the inscribed angle

mXY

Answer:

8

Step-by-step explanation:

If you add the ratios together, it is equal to 9

Since NQ = 9, 9/9=1

So each unit is 1

Then you can just add 5*1 + 3*1

Which is 8

Answer:

60 pounds of meat

Step-by-step explanation:

Number of lions = 4

Pounds of meat consumed = 7 pounds each

Number of cubs = 8

Pounds e meat consumed = 4 pounds each

Amount of meat consumed each day by the lions = 4 × 7 + 8 × 4

Multiply first

= 28 + 32

= 60 pounds of meat

The lions consume 60 pounds of meat each day.

Answer:

5 text messages

Step-by-step explanation:

Given data

The total number of text= 25

20% of the text message were to your best friend

Let us find 20% of 25

=20/100*25

=0.2*25

=5

Hence the number of text sent to your best friend is 5 text messages

Answer:

2 dozens, $41

Step-by-step explanation:

Given data

Man Street Florist charges

$18 for a dozen roses and a

$5 delivery fee

let the number of dozens be x

and the total charge for x dozens be y

hence

y= 18x+5--------------1

Blooms and Bouquets

charges $20 for a

dozen roses and a $1

delivery fee.

let the number of dozens be x

and the total charge for x dozens be y

hence

y= 20x+1 -------------2

Equate 1 and 2 we have

18x+5=20x+1

20x-18x= 5-1

2x= 4

x= 4/2

x= 2

Hence the number of dozens is 2

the cost is (put x= 2 in eqn 1 or 2)

y= 20(2)+1

y= 40+1

y= $41
