Mariane buys 16 bags of potting soil for her father that comes in 3/4 pound bags. Part 1 How many pounds of potting soil does Marianne buy? Use the drop downs to put the correct number into the box to complete the statement. If Marianne's father calls and says he needs 15 pounds of potting soil, how many additional bags should she buy? Use the drop downs to put the correct number into the box to complete the statement.
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

PLEASE HELP!50 POINTS! Brainiest if you know how to do it. I will report you if you're just guessing or very wrong. How do I find the least common denominator in these?
Which of the following is the least common denominator for w-5/w-7 and w+8/3w?
A. 3w (w − 7)
B. w (w − 7)
C. 3w − 7
D. 3(w + 7)
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:
A. 3w (w − 7)Step-by-step explanation:
GivenFractions
(w- 5)/(w-7) and (w + 8)/3wTo findCommon denominatorSolutionWe 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:
3w(w - 7)Correct option is A
what is y when the equation is x^2 - 3xy -4y^2 =0
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))

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]

Step-by-step explanation:
2x-14x+47=0
16x+47=0
16x=-47
x=-2.9375
Answer:
x=7+√ 2 or x=7-√ 2
Step-by-step explanation:
x^2-14x+47=0
Completing the square,
x^2-14x+49-2=0
x^2-14x+49=2
x^2-7x-7x+49=2
x(x-7)-7(x-7)=2
(x-7)^2=2
x-7=√ 2 or x-7=-√ 2
x=7+√ 2 or x=7-√ 2
In 2016, the cost of 2 ounces of pure gold was $2,640. Complete the double number line to show the cost for 1, 3, and 4 ounces of gold.
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.

How do you change -3 in x^-3 to be positive?
Answer:
x^-3=1/x^3
This is how we do it.
Answer:
Take the reciprocal. 1/x^3
Step-by-step explanation:
When you take the reciprocal of a number or a variable, the exponent changes sign.
Find the inverse function of
y =x-5/6
[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]

A biker travels the 120 mi from New York , NY to Wilmington, DE in 8 hours. A bus, a truck, and a rider on a horse take the same route as the biker. At what speed does each of them travel if it takes them 2 hours, 2.5 hours, and 18.75 hours respectively to reach Wilmington? Do the speed and the time vary directly or inversely proportional when the same distance is traveled? Explain why.
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.

The ratio of books
to magazines in the
children's section at the
library is 5-2. If there
are 225 books, calculate
the number of
magazines.
50 magazines
because ratio is division and 225/5 is 25 and you multiply the 2 by 25 and you get 50
There are 64 magazines in the library.
What is mean by Ratio?A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.
We have to given that;
The ratio of books to magazines in the children's section at the library is 5: 2.
Let number of books = 5x
And, Number of magazines = 2x
Here, There are 225 books in the library.
Hence, We can formulate;
⇒ 5x + 2x = 225
⇒ 7x = 225
⇒ x = 32
Hence, Number of magazines = 2x
= 2 × 32
= 64
