Answer:

70 centimeters.

1 meter = 100 centimeters

--> 100-30=70 centimeters.

Answer:

There are 100 cm in 1 m.

So with that, if you put 4.5 m in cm you get 450 cm of ribbon.

Then divide 450 by 4.5 to see how many times you can take out 4.5 cm from the amount you have.

450/4.5 = 100

So you can get 100 pices of ribbon each 4.5 cm

from 4.5 m of ribbon

Center: (2,-6)

Radius: 8

Answer:

Step-by-step explanation:

They say  "solve" the triangle,  means just find all the sides and all the angles is all they are asking by "solve"   .. saying "solve" sounds so ominous  :/  like.. good luck with this... nobody can do it..  :D ..  which there are math questions like that.  soooo anyway,  let's find AC , I'll call is side b , then using law of cosines, where AC = b  , a = 9 and c=21, and angle B = 91°,  then

b = sq rt[ a^2+c^2 - 2*a*c*cos(B) ]

b = sq rt[ 9^2 +21^2 -2*9*21*cos(91)]

b = sq rt [ 81 +441 -378 * (-0.0174524 )]

b = sq rt [ 522 + 6.597]

b = sq rt [528.597]

b = 22.991

side AC = 23.0  ( rounded to nearest 10th)

now that we have all three sides lets use law of sines to solve the angles, b/c it's easier  :P    call me "lazy"  maybe ?    or call me "maybe"   :D :D  the song, ofc.   :D anyway

sin(91) / 22.991 = sin(C) /21

arcSin [ 21*sin(91) / 22.991] = C

arcSin[ 0.91326 ] = C

65.96 ° = C

C = 66.0 °

and then the same for angle A

Sin(91)/22.991 = sin(A) / 9

arcSin [ 9* sin(91) / 22.991 ] = A

arcSin [ 0.3913979 ] =A

23.04 ° = A

A = 23.0 °

let's add up the 3 angles to see if we get 180 or very very close

180.0015 °  ohh that's pretty close , nice I think the answers are right :P

23 +66+91=180  so the rounding to the nearest 10th makes them perfect , great ,  :)

Answer:

9. option D ---> (3, -5)

10. option D ---> E = 4.5H + 35

Step-by-step explanation:

9. According to the rule of reflecting across the y-axis :-

(x, y) ---> (-x, y)

(-3, -5) ---> (3, -5)

3 was already a negative, so we would flip the signs making it positive and keeping -5 as it is.

10. When we read the questions it gives us some information that is useful to form an equation.

Now we can put all of the information into an equation.

E = 4.5H + 35

I would appreciate if you give me the branlist or not. Hope this helps and stay safe, happy, and healthy, thank you :) !!

Answer:

Roberto can buy up to 7 video games max.

Step-by-step explanation:

max Roberto can spend = $200

video game = $25.50 each

equation:

25.50g = 200

divide each side by 25.50:

[tex]\frac{25.50g}{25.50} = \frac{200}{25.50}[/tex]

= 7.84

7 video games x 25.50 each = 178.50

200 - 178.50 = 21.50 remaining

Step-by-step explanation:

Answer:

78

Step-by-step explanation:

Remark

There are two similar triangles in the diagram: ΔYZX and  ΔVWX.

That being true a ratio can be set up as

VW / ZY = WX / XZ

Givens

VW = 104

ZY = 8

WX = ?

XZ = 6

Solution

104 / 8 = WX / 6

104 * 6 / 8 = WX

WX = 78

So the width of the lake is 78 meters

Yes, it is Quadratic.

D. Yes; it can be rewritten in the form y = ax2 + bx + c.

There is no b, so you would skip over it

3y = -7x + 8

isolate the y (divide 3 from both sides)

(3y)/3 = (-7x + 8)/3

y = (-7x + 8)/3 would be your answer

D. Yes; it can be rewritten in the form y = ax2 + bx + c. (is actual answer)

hope this helps

Answer:

3 hours times 6.80= 20.40

2 hours times 6.20= 12.40

20.40 + 12.40 = 32.80

32.80 ÷ the 5 hours= $6.56 per hour average

Answer: The answer is listening to others and benefits.

Step-by-step explanation: I got it right here's proof.

Answer: listening to others and benefit

Step-by-step explanation:

Answer:

Expected benefit under this policy = $ 2694

Step-by-step explanation:

Given - An insurance policy on an electrical device pays a benefit of

            4000 if the device fails during the first year. The amount of the

            benefit decreases by 1000 each successive year until it reaches 0.

            If the device has not failed by the beginning of any given year, the

            probability of failure during that year is 0.4.

To find - What is the expected benefit under this policy ?

Proof -

Let us suppose that,

The benefit = y

Given that, the probability of failure during that year is 0.4

⇒Probability of non-failure = 1 - 0.4 = 0.6

Now,

If the device fail in second year , then

Probability = 0.6×0.4

If the device fail in third year, then

Probability = 0.6×0.6×0.4 = 0.6² × 0.4

Going on like this , we get

If the device is failed in n year, then

Probability = 0.6ⁿ⁻¹ × 0.4

Now,

The probability distribution is-

Benefit , x       4000       3000             2000            1000              0

P(x)                 0.4         0.6×0.4         0.6² × 0.4     0.6³ × 0.4     1 - 0.8704

                      (0.4)       (0.24)            (0.144)         (0.0864)       (0.1296)

At last year, the probability = 1 - (0.4+ 0.24+ 0.144+ 0.0864) = 1 - 0.8704

Now,

We know that,

Expected value ,

E(x) = ∑x p(x)

       = 4000(0.4) + 3000(0.24) + 2000(0.144) + 1000(0.0864) + 0(0.1296)

       = 1600 + 720 + 288 + 86.4 + 0

       = 2694.4

⇒E(x) = 2694.4 ≈ 2694

∴ we get

Expected benefit under this policy = $ 2694

Answer:

the answer is 0.1 dime

Step-by-step explanation:

2 1/2 % = 2.5%

2.5% of 4 = 4 * 2.5/100

= 0.1 dime

Amount left with Mathew = 4 - 0.1 = 3.9 dimes

Mathew has 3.9 dimes left with him.

Answer:

a) the probability that a randomly selected person fails to meet the activity guidelines or eats a poor diet is 0.83

b) the probability that a randomly selected person is leading a healthy lifestyle is 0.17

c) the probability that they all 4 people eat a poor diet assuming independence is 0.05308

d) the probability that the first one meets the Physical Activity Guidelines and the last two do not is 0.1364

Step-by-step explanation:

Given the data in the question;

Let E represent the events

E1 = P( person fails to meet CDC Physical Activity Guidelines ) = 0.77

E2 = P( person eats a poor diet ) = 0.48

E3 = P(E1 ∩ E2) = P( both ) = 42

a) What is the probability that a randomly selected person fails to meet the activity guidelines or eats a poor diet?

the probability that a person eats a poor diet or fails to meet the activity guidelines will be;

P( E1 ∪ E2 ) = P(E1) + P(E2) - P(E1 ∩ E2)

so we substitute

P( E1 ∪ E2 ) = 0.77 + 0.48 - 0.42 = 0.83

Therefore, the probability that a randomly selected person fails to meet the activity guidelines or eats a poor diet is 0.83

b) Find the probability that a randomly selected person is leading a healthy lifestyle. That is, they meet the Physical Activity Guidelines and eat a diet that is not poor?

In the light of De-Morgan’s Laws

P( [tex]E_1^c[/tex] ∩ [tex]E_2^c[/tex] ) = 1 - P( E1 ∪ E2 )

so

P( [tex]E_1^c[/tex] ∩ [tex]E_2^c[/tex] ) = 1 - 0.83 = 0.17

Therefore, the probability that a randomly selected person is leading a healthy lifestyle is 0.17

c)  If you randomly select 4 people, what is the probability that they all eat a poor diet assuming independence?

if we select 4 people;

E2 = P( person eats a poor diet ) = 0.48

so

P = ( 0.48 )⁴ = 0.05308

Therefore, the probability that they all 4 people eat a poor diet assuming independence is 0.05308

d)  If you randomly select 3 people, what is the probability that the first one meets the Physical Activity Guidelines and the last two do not?

we select 3 people;

P( person fails to meet CDC Physical Activity Guidelines ) = 0.77

P( person meet CDC Physical Activity Guidelines ) = 1 - 0.77 = 0.23

so

P = 0.23 × ( 0.77)²

P = 0.1364

Therefore, the probability that the first one meets the Physical Activity Guidelines and the last two do not is 0.1364

Hello.

In your question, we can see that the points Q, P, and R can be assumed that they are in a straight line, meaning that the angle measures will add up to 180 (think of half a circle, which is 360 degrees).

This means that every angle added up will add up to 180 degrees.

Meaning we can set up the below equation:

[tex](8b-12)+(b)+(2b+5)=180[/tex]

[tex]8b-12+b+2b+5=180[/tex]

[tex]11b-7=180[/tex]

[tex]11b=187[/tex]

[tex]b=17[/tex]

After finding [tex]b[/tex], we can plug it back in to each expression for each angle measure.

∠QPS = [tex]8b-12=8(17)-12=124[/tex]

∠SPT = [tex]b=17[/tex]

∠TPR = [tex]2b+5=2(17)+5=39[/tex]

Hope this helps!
