Step-by-step explanation:
Maya and Edward cut lawns in the summer to earn spending money. Maya has a newer lawnmower, so Edward takes 15 minutes longer to cut a lawn than Maya. Working together they can both cut a lawn in 18 minutes. How long would it take Edward to cut a lawn alone?
Answer:
The answer would be 45 minutes.
Step-by-step explanation:
Just skipped to the answer on Edementum.
A fraction is a way to describe a part of a whole. The time it takes Edward to cut the lawn alone is 45 minutes.
What is a Fraction?A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.
Let the time taken by Maya to lawn the garden be x.
The rate at which Maya lawn = 1/x
Maya has a newer lawnmower, so Edward takes 15 minutes longer to cut a lawn than Maya. Therefore,
The rate at which Edward lawn = 1/(x+15)
Working together they can both cut a lawn in 18 minutes.
The rate at which they both work = 1/18
Now, the rate of working can be compared as,
1/x + 1/(x+15) = 1/18
(x+ x + 5)/x(x+15) = 1/18
(2x + 15)18 = x(x+15)
36x + 270=x² + 15x
x²-21x-270=0
x = 30, -9
Since time can not be negative. Therefore, the time it takes Edward to cut the lawn alone is,
x + 15
= 30 + 15
= 45 minutes
Hence, the time it takes Edward to cut the lawn alone is 45 minutes.

The amount of concrete, c, needed to make a walkway around a circular swimming pool varies directly as the square of the diameter, d, of the
pool. Which statement is true?
OA If the diameter of the pool is doubled, the amount of concrete needed is multiplied by 2.
•B. If the diameter of the pool is doubled, the amount of concrete needed is multiplied by 4.
OC. If the diameter of the pool is halved, the amount of concrete needed is multiplied by 2.
OD. If the diameter of the pool is halved, the amount of concrete needed is multiplied by 4.
Answer:
Step-by-step explanation:
For all Plato users
The amount of concrete needed after doubling the diameter of the circle will be multiplied by 4 by the initial amount. Hence, the correct option is (B).
What are direct proportions?Direct proportions are the proportions where a variable changes with another variable by direct mean so the coefficient of constant will be direct.
For example y ∝ x² here y varies with respect to x square.
y = Kx² where k will be the coefficient of constant.
Given that amount is Amount ∝ d²
Amount = k d²
By doubling the diameter
Amount = k (2d)²
Amount = 4 kd²
Amount = 4 × initial amount hence, the amount will be multiplied by 4.

9. Anna wants to take horseback riding lessons.
She is given $200 for her birthday to cover the
cost. She has to pay $20 for grooming supplies.
If the lessons are $30 an hour, how many lessons
can Anna take?
The answer is x = 6
Let us first define x to be the number of hours of riding lessons she can take.
X = Hours of lessons
Now, she has $200, she needs to pay $20 for grooming supplies, and the lessons cost $30 an hour. We to find the maximum amount of hours of lessons she can take, so in other words, we want to make her broke. To do this, we first convert the words into an equation:
200 - 20 - 30x = 0
Simplifying, we get
180 = 30x

A cork has a mass of 3 grams and a volume of 16 cm3
. Calculate the density.
Answer:
0.1875, or 3/16
Step-by-step explanation:
The formula for density is mass/volume.
I hope this helps :)
Answer:
[tex]{\boxed {\sf \frac{3}{16} \ g/cm^3}}[/tex]
or
[tex]\boxed {\sf 0.1875 \ g/cm^3}}[/tex]
Step-by-step explanation:
Density can be found by dividing the mass by the volume.
[tex]\rho= \frac{m}{v}[/tex]
The mass of the cork is 3 grams and the volume is 16 cubic centimeters.
[tex]m= 3 \ g\\v= 16 \ cm^3[/tex]
Substitute the values into the formula.
[tex]\rho = \frac{3 \ g }{16 \ cm^3}[/tex]
Divide.
[tex]\rho=\frac {3}{16} \ g/cm^3[/tex]
[tex]\rho=0.1875 \ g/cm^3[/tex]
The density of the cork is 3/16 or 0.1875 grams per cubic centimeter.

The intensity,I, of light received at a source varies inversely as the square of the distance, d, from the source. If the light intensity is 33 foot-candles at 20 feet, find the light intensity at 5fee
Answer:
The light intensity is 528 foot-candles at 5 feet
Step-by-step explanation:
If x and y are in inverse variation, then x y = k, where k is the constant of variation
In the given question
∵ The intensity I, of light received at a source, varies inversely as the
square of the distance d, from the source
→ That means I × d² = k, where k is the constant of variation
∴ I × d² = k
∵ I = 33 foot-candle at d = 20 feet
→ Substitute them in the rule above to find k
∴ 33 × (20)² = k
∴ 33 × 400 = k
∴ 13200 = k
→ Substitute the value of k in the equation
∴ I × d² = 13200 ⇒ equation of variation
∵ d = 5
→ Substitute it in the equation to find I
∵ I × (5)² = 13200
∴ I × 25 = 13200
→ Divide both sides by 15
∴ I = 528
∴ The light intensity is 528 at 5 feet

The graphs below have the same shape what is the equation of the blue graph
Answer: g(x) = (x-2)^2 + 1. Choice C
===========================================================
Explanation:
The graphs have the same shape, which means they have the same 'a' value.
In this case, a = 1.
The vertex of the red graph is (0,0).
The vertex of the blue parabola is (2, 1)
The red curve has been shifted 2 units to the right and 1 unit up.
Since the vertex of the blue graph is (2,1), this means h = 2 and k = 1.
Plug a = 1, h = 2 and k = 1 to get...
y = a(x-h)^2 + k
y = 1(x-2)^2 + 1
g(x) = (x-2)^2 + 1
Answer:
C.
Step-by-step explanation:
Since the blue graph shifted up by 1 unit, it would be +1 at the end of the quadratic function. Then, because the graph also shifted to the right 2 units, the blue graph subtracts from f(x)=x^2 (it does the opposite).
Duane recorded the temperature outside his window one morning. On the second day, the temperature went up 7 degrees. On the third day, the temperature went down 10 degrees. On the fourth day, the temperature went down 6 degrees, and it was 1°F. What was the temperature on the first day?
Answer:
The temperature on the first day was 10 °F.
Step-by-step explanation:
Let's find the temperature in every single step starting from the fourth day:
[tex]T_{4} = T_{3} - 6 F = 1 F[/tex]
[tex] T_{3} = 1 F + 6 F = 7 F [/tex]
Then, the temperature of the third day was 7 °F
On the third day:
[tex] T_{3} = T_{2} - 10 F = 7 F [/tex]
[tex] T_{2} = 7 F + 10 F = 17 F [/tex]
Hence, the temperature on the second day was 17 °F.
Now, on the second day:
[tex]T_{2} = T_{1} + 7 F = 17 F[/tex]
[tex] T_{1} = 17 F - 7 F = 10 F [/tex]
Therefore, the temperature on the first day was 10 °F.
I hope it helps you!

C.B. Clothing ordered sweaters at a wholesale cost of $20 each. The store marked up the price 50 percent above the wholesale cost to use as their selling price. After every month that the sweater didn't sell, the store reduced the selling price by 20 percent. After how many monthly price reductions did the price dip below the wholesale cost? after 1 monthly price reduction after 2 monthly price reductions after 3 monthly price reductions after 4 monthly price reductions
Answer: after 2 monthly price reductions
Step-by-step explanation:
Given that :
Wholesale cost = $20 each
Markup = 50%
Selling price = $20 + (50% * 20) = $30
After each month selling price reduces by 20%;
Dip in price per month for which item didn't sell ;
Let m = Number of months
$30 - 0.2(30)m = $30 - 6m
After how many monthly price reductions did the price dip below the wholesale cost?
$30 - 6m < $20
-6m < $20 - $30
-6m < - $10
m > 10/6
m > 1.667
m = 2
After 2 monthly price reduction
