Answer:

Additional bags required = 4

Step-by-step explanation:

Marianne buys number of bags of potting soil = 16

Each bag weighs = [tex]\frac{3}{4}[/tex] pounds

Total weight of 16 soil bags = [tex]16\times \frac{3}{4}=12[/tex] pounds

If Marianne's father requires potting soil = 15 pounds

Amount of additional soil he will require = 15 - 12

                                                                   = 3 pounds

Therefore, number of additional soil bags required = [tex]\frac{\text{Weight of soil required}}{\text{Soil in each bag}}[/tex]

                                                                                     = [tex]\frac{3}{\frac{3}{4}}[/tex]

                                                                                     = [tex]3\times \frac{4}{3}[/tex]

                                                                                     = 4 bags

Additional bags required by Marianne= 4

The answer to your question is x=200

Step-by-step explanation:

1/5x-10+10=30+10(add 10 both sides)

1/5x=40

x=200

Answer:

The slope

Step-by-step explanation:

[tex]f(x) = y = x - \frac{5}{6} \\ [/tex]

Subtract the sides of the equation plus 5/6

[tex]y + \frac{5}{6} = x \\ [/tex]

So ;

[tex] {f}^{ - 1}(x) = x + \frac{5}{6} \\ [/tex]

Answer:

sin2x = [tex]\frac{30}{34}[/tex]

Step-by-step explanation:

Given

tanx = [tex]\frac{3}{5}[/tex] = [tex]\frac{opposite}{adjacent}[/tex]

This is a right triangle with legs 3 and 5

Let the hypotenuse be h , then using Pythagoras' identity

h² = 3² + 5² = 9 + 25 = 34 ( take the square root of both sides )

h = [tex]\sqrt{34}[/tex]

Thus

sinx = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{3}{\sqrt{34} }[/tex]

cosx = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{5}{\sqrt{34} }[/tex]

Hence

sin2x = 2sinxcosx = 2 × [tex]\frac{3}{\sqrt{34} }[/tex] × [tex]\frac{5}{\sqrt{34} }[/tex] = [tex]\frac{2(3)(5)}{\sqrt{34}(\sqrt{34}) }[/tex] = [tex]\frac{30}{34}[/tex]

Answer:

c(10)=40

c(15)=52.5

Step-by-step explanation:

c(10) means you plug 10 into your x same with (c15) you plug in 15 so for c(10) it would be 2.5(10) + 15 which is 40

The value of c(10) and c(15) is 40 and 65 respectively.

The given function is c(x) = 2.5x + 15.

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.

Now, c(10)=2.5(10)+15=40

c(15)=2.5(15)+15=52.5

Given c(20) = 65

So, 65=2.5x+15

⇒50=2.5x

⇒x=20

Therefore, the value of c(10) and c(15) is 40 and 65 respectively.

Step-by-step explanation:

The Proportionality Constant is used to compare values that are proportional.

When two variables are proportional to each other , change in one cause the change in the other .

There are two types of proportion, Direct and Indirect.

When on increasing one variable the other increases and vice versa it is called direct proportion .

When on increasing one variable the other decreases and vice versa it is called indirect proportion .

Answer:

Step-by-step explanation:

Answer:

First, remember the relation:

Distance = Speed*Time.

We know that the distance is 120mi.

A) For the biker we know that:

Time  = 8hours.

Speed = Distance/Time = 120mi/8h = 15 mi/h.

B) For the bus we know that:

Time = 2 hours.

Speed = Distance/Time = 120mi/2h = 60 mi/h.

C) For the truck we know that:

Time = 2.5 hours.

Speed = Distance/Time = 120mi/2.5h = 48 mi/h.

D) For the rider on a horse we know that:

Time = 18.75 hours.

Speed = Distance/Time = 120mi/18.75h = 6.4 mi/h.

E) The equation for the speed is:

Speed = Distance/Time.

You can see that time is in the denominator, this means that if for a fixed distance, the time increases, then the denominator increases, which would imply that the speed decreases.

Then the speed is inversely proportional to the time when the distance is fixed.

Answer:

A) 3w(w-7)

Step-by-step explanation:

[tex]\frac{w-5}{w-7} and \frac{w+8}{3w}[/tex]

w-7 is a binomial, and 3w is a monomial. Because you cannot put one denominator into the other or multiply both denominators by a number when you have this type of difference where multiplying by a number won't get you the same result, you must multiply them each other.

Therefore:

3w(w-7) would be your LCD.

Answer:

Step-by-step explanation:

Fractions

We observe that the fractions can't be simplified any more and they are in the simplest form

Next, the denominators w - 7 and 3w don't have common factors

Therefore the common denominator is the product of denominators:

Answer:

y = 1/8 (5 sqrt(x^2) - 3 x) or y = 1/8 (-3 x - 5 sqrt(x^2))

Step-by-step explanation:

Solve for y:

-4 y^2 - 3 x y + x^2 = 0

Hint: | Multiply both sides by a term to make the coefficient of y^2 positive.

Multiply both sides by -1:

4 y^2 + 3 x y - x^2 = 0

Hint: | Using the quadratic formula, solve for y.

y = (-3 x ± 5 sqrt(x^2))/8:

Answer: y = 1/8 (5 sqrt(x^2) - 3 x) or y = 1/8 (-3 x - 5 sqrt(x^2))

Step-by-step explanation:

Answer:

1 would be 1320

3 would be 3960

4 would be 5280

Step-by-step explanation:

The cost of 1, 3 and 4 ounces of gold in 2016 was $1,320, $3,960 and $5,280 respectively.

Cost of 2 ounces of gold in 2016 = $2,640

Cost of 1 ounce of gold in 2016 = Cost of 2 ounces of gold in 2016 ÷ 2

= $2,640 ÷ 2

= $1,320

Cost of 3 ounces of gold in 2016 = Cost of 1 ounce of gold in 2016 × 3

= $1,320 × 3

= $3,960

Cost of 4 ounces of gold in 2016 = Cost of 1 ounce of gold in 2016 × 4

= $1320 × 4

= $5,280

Therefore, the cost of 1, 3 and 4 ounces of gold in 2016 are $1,320, $3,960 and $5,280 respectively.

Answer:

d=7

Step-by-step explanation:

Answer: There are 16 quarters and 10 dimes.

Step-by-step explanation:

Let x = Number of quarters

y= Number of dimes.

As per given,

x+y = 26  (i)

x= y+6  (ii), substitute this in (i), we get

y+6+y= 26

⇒2y+6=26

⇒ 2y = 26-6=20

⇒ 2y =20

⇒ y =10   [Divide both sides by 2]

Put this in (ii),  x= 10+6 =16

So there are 16 quarters and 10 dimes such that 16 (0.25)+10(0.10)= $5 .
