Answer:

−28hw+9w+3

Step-by-step explanation:

5w(1-8h) = 5w-40wh

+12wh = -28hw

-28hw+5w+5w = -28hw+10w

-w = -28hw+9w

+3 = -28hw+9w+3

Answer:

25%

Step-by-step explanation:

Divide 89.99 or 90 (since you are rounding) by 120, and you get .7499 or 75%.  You have 25% ($30) as the discount because 90 is 75% of $120.

A)

   a

———=8       :a=64

5+3  

Steps:Multiply both sides by 8

     ———-=8  ·   8

      5+3

B)

3b/7 - 1 = 5

Add 1 in both sides

3b/7 - 1 + 1 = 5 + 1

3b/7 = 6

Multiply both sides by 7 and then divide by 3.

3b/7 . 7/3 = 6 . 7/3

b = 2.7

b = 14

Answer: 44%

Step-by-step explanation:

Area of the first hole = 30 × 30 = 900

Area of second hole = (30+6) × (30+6) = 36 × 36 = 1296

Percentage increase = (1296 - 900) / 900 × 100

= (396 / 900) × 100

= 44%

Answer:

Step-by-step explanation:

this system doesnt have any solutions

if you multiply the first equation by 2 you will get

2x-6y=14

second equation is

2x-6y=12

the result will -12=14

no solutions

Equation of the ellipse = 3x² + 5y² = 32

The equation of an ellipse is given by,

[tex]\sf \dfrac{x^2}{a^2} +\dfrac{y^2}{b^2} =1[/tex]

Given that the ellipse passes through the point (-3, 1)

Hence,

[tex]\sf \dfrac{(-3)^2}{a^2} +\dfrac{1^2}{b^2} =1[/tex]

Cross multiplying we get,

Multiply by 4 on both sides,

Also by given the ellipse passes through the point (2, -2)

Substituting this,

[tex]\sf \dfrac{2^2}{a^2} +\dfrac{(-2)^2}{b^2} =1[/tex]

Cross multiply,

Subtracting equations 2 and 1,

Substituting in 2,

Substituting the values in the equation for ellipse,

[tex]\sf \dfrac{x^2}{32/3} +\dfrac{y^2}{32/5} =1[/tex]

[tex]\sf \dfrac{3x^2}{32} +\dfrac{5y^2}{32} =1[/tex]

Multiplying whole equation by 32 we get,

3x² + 5y² = 32

Answer:

3 miles

Step-by-step explanation:

Slope is simply the change in position per unit rate. We could conclude that the steepness of the Applachian is the rate of change in position per unit time. Since the distance hiked on the Applachian is said to be 3 miles per hour, then we can conclude that the slope of the applachian is 3 miles

This is the change in miles / change in time.

Chang in miles = 3

Change in time = 1

Slope = 3/1

Slope = 3

Answer:

0.42

Step-by-step explanation:

given:

P (penny) = 1/4

P (dime) = 1/3

since the only other possibility is to pick a nickel, hence

P (nickel)

= 1 - 1/4  - 1/3

= 5/12

= 0.4166667

= 0.42 (nearest hundredth)

Answer:

Correct Answer is B. The first equation in B is the sum of the equations in A, while the other is obtained  by multiplying the first equation in A by 2.

Step-by-step explanation:

As given,

A : 6x + 8y = -10     .......equation (1)

     2x - 5y = 12      .......equation (2)

B : 8x + 3y = 2         .......equation (1)

  12x + 16y = - 20    .......equation (1)

Correct Answer is B. The first equation in B is the sum of the equations in A, while the other is obtained  by multiplying the first equation in A by 2.

Proof :

The first part says that ,

Sum of equation (1) of A and equation (2) of A = Equation (1) of B

Firstly , find the Sum of equation (1) of A and equation (2) of A

⇒6x + 8y + 2x - 5y = -10 + 12

⇒8x + 3y = 2

this is same as equation (1) of B

So, it satisfies the first part

The second part says that,

The equation (2) of B is obtained by multiplying the first equation in A by 2.

It means , if the equation (1) is multiplied by 2 = equation (2) of B

Firstly , if the equation (1) is multiplied by 2 , we get

2 ( 6x + 8y = -10 )

⇒ 2 ( 6x + 8y ) = 2 ( -10)

⇒ 12x + 16y = -20

this is same as equation (2) of B

So, it satisfies the second part.

Answer:

the number of hours does sidney skate in all is 9.8 hours

Step-by-step explanation:

The computation of the number of hours does sidney skate in all is as follows:

= Last month + this month

[tex]= 1 \frac{1}{10} + 8 \frac{7}{10}\\\\= \frac{11}{10} + \frac{87}{10}\\\\= \frac{98}{10}[/tex]

= 9.8 hours

Hence, the number of hours does sidney skate in all is 9.8 hours

Answer:

a.) PED = 5

b.) PED = 5

c.) PED = 0.05

Step-by-step explanation:

Here , PED = Price elasticity of demand

a.)

Given - The price of a smartphone is currently £200, and the quantity demanded is 4m. Next year the price falls to £180 and the quantity demanded rises to 6m.

PED = (Change in quantity demanded)×[tex]\frac{Initial Price}{Initial Quantity demanded}[/tex]

Now,

Change in quantity demanded = [tex]\frac{6 - 4}{180 - 200}[/tex] = [tex]\frac{2}{20} = \frac{1}{10}[/tex]

⇒PED = [tex]\frac{1}{10}[/tex]×[tex]\frac{200}{4}[/tex] = 5

b.)

Given -The price of pens today is £1, and the quantity demanded is 1m. Next year the price rises to £1.10 and the quantity demanded falls to 950,000.

Change in quantity demanded = [tex]\frac{1000000 - 950000}{1.10- 1}[/tex] = [tex]\frac{50000}{0.10} = 500000[/tex]

⇒PED = [tex]500000[/tex]×[tex]\frac{1}{1000000}[/tex] = 5

c.)

Given -The price of a daily newspaper today is £1.50p, and the quantity demanded is 2m. Next year the price falls by 30p and the quantity demanded rises to 2.2m

Change in quantity demanded = [tex]\frac{2.2 - 2}{30 - 1.50}[/tex] = [tex]\frac{0.2}{28.50} = \frac{20}{2850} = \frac{2}{285}[/tex]

⇒PED = [tex]\frac{2}{285}[/tex]×[tex]\frac{1.50}{2}[/tex] = [tex]\frac{15}{2850}[/tex]= [tex]\frac{1}{190}[/tex] = 0.005
