Answer:

97 boxes

Explanation:

4,830÷50= 96.6

You then have to round 96.6 up and you get 97.

To check your answer:

97×50= 4,850

Even though having 97 boxes leaves more room for envelopes, having 96 boxes will leave all the boxes full with remaining envelopes. 96 boxes isn't enough for 4,830 envelopes.

Answer:

Step-by-step explanation:

A.

Given parameter:

  Side length  = 9cm

Unknown;

Area of the square  = ?

Solution:

The shape given is a square.

 Area of a square  = L²

 L is the side length

  Insert the parameters and solve;

     Area of the square  = 9²  = 81cm²

B.

Given parameters:

Area of the square = 9cm²

Unknown:

Side length  = ?

Solution:

The shape is a square;

  Area of a square  = L²

         9  = L²

          L = √9 = 3cm

Answer:

The probability is  [tex]P( 0.2 < p < 0.3) = 0.89751[/tex]

Step-by-step explanation:

From the question  we are told that

   The population proportion is  p =  0.25

   The sample size is  n  =  200  

Generally given that the sample size is large the mean of this sampling distribution is mathematically represented as [tex]\mu_{x} = p = 0.25[/tex]

 Generally the standard deviation is mathematically represented as

        [tex]\sigma = \sqrt{ \frac{ p (1- p ) }{n} }[/tex]

=>     [tex]\sigma = \sqrt{ \frac{ 0.25(1- 0.25 ) }{200} }[/tex]

=>     [tex]\sigma = 0.03062[/tex]

Generally the probability that between 20% (0.2) to 30% (0.3) of the households in the sample have a burglar alarm is mathematically represented as  

      [tex]P( 0.2 < p < 0.3) = P(\frac{ 0.2 - 0.25}{ 0.03062 } < \frac{p- \mu_{x}}{\sigma } < \frac{ 0.2 - 0.25}{ 0.03062 } )[/tex]

[tex]\frac{p -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \  p )[/tex]

=>   [tex]P( 0.2 < p < 0.3) = P(-1.6329 < Z <1.6329 )[/tex]

=>   [tex]P( 0.2 < p < 0.3) = P( Z< 1.6329) - P( Z <- 1.6329 )[/tex]

From the z table  the area under the normal curve to the left corresponding to  1.6329 and  -1.6329  is

    [tex]P( Z< 1.6329) = 0.94875[/tex]

and

    [tex]P( Z <- 1.6329 ) = 0.051245[/tex]

So

   [tex]P( 0.2 < p < 0.3) = 0.94875 - 0.051245[/tex]

=> [tex]P( 0.2 < p < 0.3) = 0.89751[/tex]

Answer:

Step-by-step explanation:

The equation of shifted function y = ax² is y = a(x-h)²+k, where h tells us how many units we move left (h<0) or right (h>0) and k tells how many units up (k>0) or down (k<0)

y = x² - 20 = 1(x - 0)² + (-20)   ⇒  k = -20<0

So it's shifted 20 units down.

Answer:

y = -10/3x - 17/3

2- Equilateral triangle

3- Isosceles triangle

4- Equilateral triangle

Here's the explanation if you need it :

For a scalene triangle, all the sides are different whereas an Equilateral triangle has equal sides. And finally for an Isosceles triangle, two sides are equal.

Answer:

20cm Perimeter: 90

Step-by-step explanation:

Hope this helps!(^-^)

Step-by-step explanation:

area of rectangular sheet is 500 CM square

length =25cm

area =l×b

500cm2=25cm×b

500cm2÷25cm=b

20cm=b

b=20cm

again,

perimeter =2(l+b)

perimeter =2(25cm+20)

perimeter =2×45

perimeter =90cm

Answer:

Domain

[tex]x\in [0\,s,30\,s][/tex]

Range

[tex]h \in [0\,ft,330\,ft][/tex]

The h-Intercept represents the initial height of the balloon. The balloon has an initial height of 330 feet.

The x-Intercept represents the time when the balloon reaches the ground. The balloon takes 30 seconds to descend and reach the ground.

The slope represents the ratio of the change in the elevation of the balloon to the change in time. A slope of -11 means that balloon descends 11 feet per second.  

Step-by-step explanation:

Both the time (domain), measured in seconds, and the height (range), measured in feet, are positive variables. The hot air balloon start at a height above and descends to the ground. Which means that domain and range of the function are, respectively:

Now we find the upper bound of the height of the hot air balloon. If we know that [tex]t = 0\,s[/tex], then the upper bound is:

[tex]h(0) = -11\cdot (0)+330[/tex]

[tex]h(0) = 330\,ft[/tex]

Range

[tex]h \in [0\,ft,330\,ft][/tex]

Now we find the upper bound of time. If we know that [tex]h = 0\,ft[/tex]. then the upper bound is:

[tex]-11\cdot x +330 = 0[/tex]

[tex]11\cdot x = 330[/tex]

[tex]x = 30\,s[/tex]

Domain

[tex]x\in [0\,s,30\,s][/tex]

The h-Intercept represents the initial height of the balloon. The balloon has an initial height of 330 feet.

The x-Intercept represents the time when the balloon reaches the ground. The balloon takes 30 seconds to descend and reach the ground.

The slope represents the ratio of the change in the elevation of the balloon to the change in time. A slope of -11 means that balloon descends 11 feet per second.

Answer:

there are 114

Step-by-step explanation:

Ratio of red marbles to black marbles is 19:1. (Data from 3rd sentence)

19+1= 20

20 units= 120 (Data from 1st sentence)

1 unit= 120/20= 6

19 units= 120-6= 114 (Values solved in working above)

Answer:

680 oranges

15 levels

Step-by-step explanation:

Add 2, add 3, add 4, add 5.....

1+3+6+10+15+21+28+36+45+55+66+78+91+105+120=680

15 levels

He can’t add a 16th level, because it would have 136 oranges, which would put him over 800.

Answer:

15 levels, 680 oranges.

Step-by-step explanation:

Guess an check. The first 15 add to 680. The 16th is 136. 680+136=810, which is over 800.

Finding the Common Ratio:

We know that the formula for the common ratio of a GP is:

r = aₙ / (aₙ₋₁)        (Where n is any integer)

replacing the values, taking n=2

r = -21 / 7

r = -3

Solving for the 15th Term:

We know that the Formula for the nth term of a GP:

G(n) = a * r ⁿ⁻¹     (where a is the first term and r is the common ratio)

replacing the values (taking n = 15 since we need the 15th term)

G(15) = 7 * (-3)¹⁴

G(15) = 33480783

Hence, the 15th term of the given GP is 33480783
