Answer:

Step-by-step explanation:

We are told that the perimeter is 48 = 2L + 2W.  This reduces to

24 = L + W.  Next, substitute, one by one, the 3 widths 10 cm, 3.6 cm and w cm:

a)  If W = 10 cm, 24 = L + W becomes 24 = L + 10, or L = 14 cm

b)  If W = 3.6 cm, 24 = L + W becomes 24 = L + 3.6, or L = 20.6 cm

c)  If W = w, 24 L + W becomes 24 = L + w, so that L = (24 - w) cm

Step-by-step explanation:

You know that it costs $60 and it is marked DOWN by 20%. Therefore, you want to find 20% of 60 which is 12. Then, you subtract $12 from the original amount to get the cost now.

Answer:

3x°

Step-by-step explanation:

50°+2x°+3x°=180°

50°+5x°=180°

collect the like terms

5x°=180°-50°

5x°=130°

x°=130°÷5°

x°=26°

2x°=2×26°=52°

3x=3×26°=78°

Answer:

0.576

Step-by-step explanation:

First, you would change the percent to a decimal which is 0.0008

Second, you would multiply that by 720 (0.0008 x 720)

Third you would find your answer by calculating it, which is 0.576.

Another way

0.0008/ 100 ×  a/720 ≡ 0.576

The value of 0.08% of 720 is 0.576.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

0.08% of 720

= 0.08/100 x 720

= 0.576

Thus,

0.576 is the value of 0.08% of 720.

Answer:

  4 + 4 = 8

  5 + 5 = 10

Step-by-step explanation:

If we assume Mr Noris restricted himself to integer facts, we require both ...

  2n > 6

  n < 6

Dividing the first inequality by 2 gives ...

  n > 3

Writing the two inequalities as a compound inequality, we have ...

  3 < n < 6

There are two integers that satisfy this requirement:

  n = 4 or n = 5

So, the doubles fact could have been either of ...

  4 + 4 = 8

Answer: y = 3b

Step-by-step explanation:

Equation of given relationship model is y = 3b.

Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is equal.

Given,

∵ each blanket requires 3 skeins of yarn

∴ b blanket requires 3b skeins of yarn

Total number of skeins = y = 3b

Hence, y = 3b

 [tex]n = 33[/tex]

1d

 [tex]n = 19[/tex]

Step-by-step explanation:

From the question we are told that

   The  probability of telesales representative making a sale on a customer call is  [tex]p = 0.15[/tex]

     The mean is  [tex]\mu = 5[/tex]

Generally the distribution of sales call  made by a  telesales representative follows a binomial distribution  

i.e  

         [tex]X  \~ \ \ \  B(n , p)[/tex]

and the probability distribution function for binomial  distribution is  

      [tex]P(X = x) =  ^{n}C_x *  p^x *  (1- p)^{n-x}[/tex]

Here C stands for combination hence we are going to be making use of the combination function in our calculators  

Generally the mean is mathematically represented as

     [tex]\mu = n* p[/tex]

=>  [tex]5= n * 0.15[/tex]

=>  [tex]n = 33[/tex]

Generally the least number of calls that need to be made by a representative for the  probability of at least 1 sale to exceed 0.95 is mathematically represented as

      [tex]P( X \ge 1) = 1 - P( X < 1 ) > 0.95[/tex]

=>    [tex]P( X \ge 1) = 1 - P( X =0 ) > 0.95[/tex]

=>    [tex]P( X \ge 1) = 1 - [ ^{n}C_0 *  (0.15 )^0 *  (1- 0.15)^{n-0}] > 0.95[/tex]

=>    [tex] 1 - [1  *  1*  (0.85)^{n}] > 0.95[/tex]

=>    [tex]  [(0.85)^{n}] > 0.05[/tex]

taking natural  log of both sides

[tex]n = \frac{ln(0.05)}{ln(0.85)}[/tex]

=>  [tex]n = 19[/tex]

Answer:

a

Step-by-step explanation:

Answer:

A. Both factors are negative, so the product will be positive

Step-by-step explanation:

Remember negative times negative will always be positive

And use the process of elimination:

You know that negative times negative is not negative so that eliminates B.

And there are two negatives in the equation not one positive and one negative so it is not choice C.

The same concept applies is for choice D.

Step-by-step explanation:

Answer:

X = 30°, y = 15° and z = 150°.

Reason: Look below.

Step-by-step explanation:

Hey there!

When we look into the figure, we find that;

For x:

x+ 2x + 90° = 180° {Being linear pair}

or, 3x = 180°-90°

or, 3x = 90°

or, x= 90°/3

Therefore, X = 30°.

For y :

2y = x = 30° {Alternate angles are equal}

or, 2y = 30°

y = 30°/2

Therefore, y = 15°

For z:

2y + z = 180° { Being linear pair}

or, 30°+z = 180°

or, z = 180°-30°

or, z = 150°

Therefore, z = 150°.

The reflection across the x-axis is an illustration of transformation, and the coordinates of the transformed point is (-4,-5)

The point is given as:

Point = (-4,5)

The rule of reflection across the x-axis is:

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

So, we have:

(x,y) -> (-4,-5)

Hence, the coordinates of the transformed point is (-4,-5)
