Answer:
No
Step-by-step explanation:
To turn 15 into 30, you multiple 15*2=30.
If you do that to the bottom of the fraction, you should be able to do it to the top however, 2*2=4 not 3 so they are not proportional.

Snow Dome Ski Resort has 65 inches of snow. It is currently snowing there at a rate of 1 inch per hour. Mt. Winterpark Ski Resort has 74 inches of snow. Currently it is snowing there at a rate of ½ inch per hour.
a) Write equations that show the amount of snow at each resort as a function of the number of hours of snow.
b) If the snow continues at this rate, when will Snow Dome have more snow than Mt. Winterpark? Show your solution process clearly.
Answer:
a) Equation for Snow Dome Ski Resort:
[tex]I_s = 65+t[/tex]
Equation for Mt. Winterpark Ski Resort:
[tex]I_m = 74+\frac{t}{2}[/tex]
b) After 19 hours, Snow dome will have more snow.
Step-by-step explanation:
Given that:
Initial snow at Snow Dome Ski Resort = 65 inches
Snowing rate at Snow Dome Ski Resort = 1 inch per hour
Initial snow at Mt. Winterpark Ski Resort = 74 inches
Initial snow at Mt. Winterpark Ski Resort = [tex]\frac{1}{2}[/tex] inch per hour
a) To write equations that show amount of snow at each resort.
Let the time in hours be represented by [tex]t[/tex].
Snow increased in [tex]t[/tex] hours by snowing at Snow Dome Ski Resort = [tex]1\times t = t[/tex] inches per hour
Snow increased in [tex]t[/tex] hours by snowing at Mt. Winterpark Ski Resort = [tex]\frac{1}{2}\times t = \frac{t}{2}[/tex] inches per hour
Equation for Snow Dome Ski Resort:
[tex]I_s = 65+t[/tex]
Equation for Mt. Winterpark Ski Resort:
[tex]I_m = 74+\frac{t}{2}[/tex]
b) Time at which Snow Dome has more snow.
Using the above equations, we can write the following inequality:
[tex]65+t>74+\dfrac{t}{2}\\\Rightarrow t-\dfrac{t}{2}>74-65\\\Rightarrow \dfrac{t}{2}>9\\\Rightarrow t>18\ hours[/tex]
After 18 hours have passed, they will have equal amount of snow.
After 19 hours, Snow dome will have more snow.
Lillian is comparing the amount of water in her bathtub and her sink. Her bathtub is 0.65 full of water. Her sink is 0.9 full of water.
Which statement is true about comparing the amount of water Lillian has in her bathtub and sink? (MGSE4.NF.7)
There is more water in the bathtub because 65 > 9
These amounts cannot be compared because decimals can only be compared if they have the same-sized whole.
These amounts cannot be compared because decimals can only be compared if the have the same place value
There is more water in the sink because 65/100 < 90/100
Answer:
Step-by-step explanation:

A beach lifeguard wants to create the largest triangular area he can with three lengths of rope to provide beach goers with maximum amount of space to play and swim in the water. Multiple buoys are attached to each rope in order to identify the designated swimming area. The first rope is 42 feet long, the second is 50 feet long, and then the third is 107 feet long. The lifeguard can only cut one of the ropes in order to create a triangle with the largest possible perimeter. How much rope, in feet, will be remaining after the lifeguard creates the designated swimming triangle? (Note: answer should be a whole number.)

x = 2
5(2 • 2 - 6) + 20

Mrs. Thompson wants to buy centerpieces to use at a party. It will cost $49 to have the centerpieces delivered plus $0.89 per centerpiece.
Part A
Let c be the number of centerpieces that Mrs. Thompson purchases. Choose the expression that shows the amount of money she will pay altogether for each centerpiece.
49c + 0.89
0.89 + c + 49
c(0.89 + 49)
49 + 0.89c
Part B
Evaluate the expression to find out how much Mrs. Thompson will pay if she orders 400 centerpieces.
Enter your answer in the box.
Answer:
a. 49 + 0.89c
b. $400
Step-by-step explanation:
Given
Delivery = $49
Cost per Centrepiece = $0.89
Solving (a): Expression that represents the equation.
From the question, we have that the number of centrepiece is represented by c
The expression can be gotten by the following formula.
Cost of Delivery + Cost per centrepiece * Number of centrepieces
This gives
49 + 0.89 * c
49 + 0.89c
Hence, the expression that represents the scenario is 49 + 0.89c
Solving (b): Payment for 400 centrepieces
To solve this, we simply substitute 400 for c in the expression in (a)
This gives:
Payment = 49 + 0.89 * 400
Payment = 49 + 356
Payment = 405
Hence, Mrs. Thompson will pay $405 for 400 centerpieces
How many ways can you arrange the word HOCKEY using only 5 letters
if each letter can only be used once?
Answer:
Total arrangement = 720
Step-by-step explanation:
Given:
Total letter n = 6
Using letter r = 5
Computation:
Total arrangement = nPr
Total arrangement = !n / !(n-r)
Total arrangement = !6 / !(6-5)
Total arrangement = 6 x 5 x 4 x 3 x 2
Total arrangement = 720

Option 4: [tex]3\frac{3}{18}[/tex] is the correct answer.
Step-by-step explanation:
The given fractions are mixed fractions. the mixed fractions have to be converted into proper fractions before performing any operation like addition, subtraction etc.
Given fractions are:
[tex]5\frac{3}{6}-2\frac{1}{3}[/tex]
Converting into proper fractions
[tex]=\frac{33}{6} - \frac{7}{3}[/tex]
Making the denominator same
We have to multiply first fraction by 3 and second by 6
[tex]=\frac{33*3}{6*3} - \frac{7*6}{3*6}\\=\frac{99}{18}-\frac{42}{18}\\=\frac{99-42}{18}\\= \frac{57}{18}[/tex]
Converting into mixed fraction: [tex]=3\frac{3}{18}[/tex]
Hence,
Option 4: [tex]3\frac{3}{18}[/tex] is the correct answer.
