Solve for a.

Pythagorean Theorem: a^2+b^2=c^2

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

Answer:

28

Step-by-step explanation:

-4+-7=28 you just reverse the division problem

Answer:

x/-7=-4

to get rid of -7, multiply -7 on both sides of the equation

(-7)x/-7=-4(-7)

x=28

 [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:

it would be 16u2-81s2 using a2-b2 formula

Answer:

13=2a+2b+c

Step-by-step explanation:

The product of terms 2 and the associated variable, is the result of double the variable. For example, a(2)= 2a.

The equation (specifically the expression and its terms on the right) cannot be simplified furthermore as there are no like terms that are able to be combined.

Answer:

[tex]x^{6}[/tex]/[tex]z^{-1}[/tex]

Step-by-step explanation:

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.

Answer:

Kindly check explanation

Step-by-step explanation:

Given the equation :

X - 5y = 20

x - 20 = 5y

(x - 20) / 5 = y

x = - 5

y = (-5 - 20) / 5 = -5

x = 0

y = (0 - 20) / 5 = - 4

x = 5

y = (5 - 20) / 5 = - 3

x = 10

y = (10 - 20) / 5 = - 2

X : _____ - 5 ___ 0 ____ 5 ____10

y : _____ - 5 ___- 4 ___ - 3 ___ - 2

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:  They would cost 48 dollars

Step-by-step explanation:

Answer:

$48

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.

Ways to find 20% of 60

Answer:

Mountain climber Joe climbed the steepest mountain

Step-by-step explanation:

In order to figure out who climbed the mountain you have to solve using the puthagreom theorem a squared + b squared = c squared

In this case you have multiply 12000 by 2 to replace a squared, you multiply 1500 by 2 to replace b squared and you leave c squared

Once you have that add the two numbers together, 2400+3000, this equals 5400

now you have 5400 = c squared, to solve you have to find the square root of 5400 giving you the rounded number of 73.48=c

After you have completed do the exact same thing with Mountain climber Bob. This gives you the rounded number of 61.64.

therefore, mountain climber Joe has climbed the steepest hill

i think bob climbed the steeper mountain

im pretty sure it's A but I may be wrong

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°.

Hope it helps...
