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

No

Step-by-step explanation:

it is not a function because 9 and three are a pair but so are 27 and 3. that makes it not a function

No, the given relation is not a function. A function is a connection between inputs in which each input is connected to precisely one output.

A function is a relationship between a number of inputs and outputs. A function is an association of inputs where each input is coupled with exactly one output. There is a range, co-domain, and domain for every function.

Given, a table where points are denoted as inputs and outputs.

To prove the relation is a function:

A relation between a collection of inputs and outputs is known as a function.

A function is a connection between inputs in which each input is connected to precisely one output.

But here, input value of 3 have two outputs.

Which gives us contradiction.

Therefore, a given relation is not a function.

Answer:

The measure of the largest interior angle is [tex]87.5^{o}[/tex].

Step-by-step explanation:

Given one of the interior angles of the triangle =  40°. Let the other interior angles be represented by b and c.

Sum of angles in a triangle is [tex]180^{o}[/tex].

So that;

b + c +  40° = [tex]180^{o}[/tex]

b + c = [tex]180^{o}[/tex] - 40°

b + c = [tex]140^{o}[/tex]

But, b and c are in the ratio 3:5

Thus,

b = [tex]\frac{3}{8}[/tex] x [tex]140^{o}[/tex]

  = [tex]52.5^{o}[/tex]

b = [tex]52.5^{o}[/tex]

c = [tex]\frac{5}{8}[/tex] x [tex]140^{o}[/tex]

  = [tex]87.5^{o}[/tex]

c = [tex]87.5^{o}[/tex]

Check:

[tex]52.5^{o}[/tex] + [tex]87.5^{o}[/tex] = [tex]140^{o}[/tex]

The measure of the largest interior angle is [tex]87.5^{o}[/tex].

Answer:

24000

Step-by-step explanation:

Step-by-step explanation:

Total number of people =3000

Let

the number of fans=17x

The number of staff=3x

[tex]{:}\longrightarrow[/tex][tex]\sf 17x+3x=3000 [/tex]

[tex]{:}\longrightarrow[/tex][tex]\sf 20x=3000 [/tex]

[tex]{:}\longrightarrow[/tex][tex]\sf x={\dfrac {3000}{20}}[/tex]

[tex]{:}\longrightarrow[/tex][tex]\sf x=150 [/tex]

500 more fans arrived

Now the new ratio=

[tex]{:}\longrightarrow[/tex][tex]\sf {\dfrac {7}{1}}[/tex]

[tex]{:}\longrightarrow[/tex][tex]\sf 7:1 [/tex]

[tex]\therefore[/tex]New ratio of fans to staff is 7:1.

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)

Ans: There are 114 red marbles.

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

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

[tex]2\frac{6}{9}[/tex] - [tex]1\frac{3}{9}[/tex] as a mixed number in its simplest form is  [tex]1\frac{1}{3}[/tex].

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

Given:

The mixed numbers are [tex]2\frac{6}{9}[/tex] and [tex]1\frac{3}{9}[/tex].

Now, subtracting the numbers,

[tex]2\frac{6}{9}[/tex] - [tex]1\frac{3}{9}[/tex],

= 24/9 - 12/9

= 12/9

= 4/3

= [tex]1\frac{1}{3}[/tex].

Therefore, the value is  [tex]1\frac{1}{3}[/tex].

Step-by-step explanation:

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.
