When y=48, x=4.2. If the value of y varies directly with x, what is the value of y when the value of x is 10.6?

Answers

Answer 1
i used ratios which i get that y=121.14 not sure tho
Answer 2

Answer:

y = 121.14

Step-by-step explanation:

For this, we will need to start by cross multiplying.

(4.2 * y) = (48 * 10.6)

4.2y = 508.8

to isolate the varible, we need to divide both sides by 4.2

y = 121.14

Step-by-step explanation:

To find the first answer add the starting height and ending height. To find how much it grew convert the total ending height of the tree to cm by multiply by 100, so 275. Then subtract 356 by 275 because you are finding out how much it grew. Take away 275 from 356 and you get 81

Eric has 240 coins in his collection. 11\20 of his coins are pennies. 4\20 of the coins are nickels. The rest f the coins are quarters. How many of the coins are quarters? Explain how you got your answer.

Answers

Answer:Number of coins that are quarters =60

Step-by-step explanation:

Total coins in possession of Eric=240

Number of coins that are pennies=11\20 x 240= 132

Number of coins that are nickels=4\20 x 240= 48

Since the rest are quarters,

Number of coins that are quarters =Total coins in possession of Eric -( Number of coins that are pennies+ Number of coins that are nickels)

=240-(132+48)

=240-180

=60

Pete and Marsha are going to buy a swimming pool. Mike wants a rectangular one that is 18 feet wide, 20 feet long, and 6 feet deep, and Marsha wants a circle shaped pool that is 20 feet across and 6 feet deep. They decide to buy the pool that cost less to fill. If the price of water is 25 cents per cubic foot, which pool do they buy and how much does it cost?

Answers

Answer:

The pool that they buy is the circular pool which Marsha wants

The cost of the circular pool is $471.25

Step-by-step explanation:

The parameters of the swimming pools which each of Pete and Marsha wants to buy is given as follows;

The dimensions of the pool Pete wants = 18 feet wide, 20 feet long and 6 feet deep

The dimensions of the circle shaped pool Marsha wants = 20 feet across and 6 feet deep

The price of water, P = 25 cents per cubic foot

The pool they decide to buy = The pool that costs less to fill

The volume of water to fill the pool Pete wants, V₁ = 18 ft. × 20 ft. × 6 ft. = 2,160 ft.³

The cost of filling the pool Pete wants, C₁ = V₁ × P

∴ C₁ = 2,160 ft.³ × 25cents/ft.³ = 54,000 cents = 540 Dollars

The volume of water to fill the pool Marsha wants, V₂ = π·(20 ft.)²/4 × 6 ft. ≈ 1,884.96 ft.³

The cost of filling the pool Marsha wants, C₁ = V₁ × P

∴ C₁ ≈ 1,884.96 ft.³ × 25 cents/ft.³ ≈ 47,124 cents = 471.24 Dollars

The pool that they buy is the circular pool that Marsha wants and it costs $471.24 to fill

Terry uses a ladder that is 12 feet tall. To be safe the ladder must make an angle of elevation of between 70-85 degrees to be safe. If he places the ladder 3 feet from the wall, is it safe?

Answers

Answer:

It is safe

Step-by-step explanation:

Using trigonometry :

Cosθ = adjacent / hypotenus

Hypotenus = length of ladder = 12 feets

Adjacent = distance between ladder and wall = 3 feets

Cosθ = 3 /12

Cosθ = 0.25

θ = cos^-1(0.25)

θ = 75.522°

To be safe ladder must be between (70 - 85)°

Sijce ladder is at an elevation of 75.22° ; then it is safe.

hey! can u help me with this?! 6 divided by 3/5 in fraction form!?!?!!?

Answers

Answer:

10/1

Step-by-step explanation:

You do

6÷ 3/5

Flip the 3/5 then multiply

6 ° 5/3

Reduce the numbers with the greatest common factor 3

So 2•5

And that's 10

Ans is 10.

The numbers in 6 divided by 3/5 are labeled below:

6 = whole number

3 = numerator

5 = denominator

To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:

6 x 5/3 = 30/3

Thus, the answer to 6 divided by 3/5 in fraction form is:

30/3

To make the answer to 6 divided by 3/5 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:

30 / 3 = 10

The answer is rounded to the nearest two decimal points if necessary.

30/3 can be simplified to 10/1.

10/1 is an improper fraction and should be written as 10.

Here are the marks of a student in four exams.

65 80 76 69

The student takes a fifth exam.
His mean mark for the five exams is 70

Work out his mark in the fifth exam.

Answers

Answer:

61 marks

Step-by-step explanation:

Given,

Marks of the four exams = 65, 80, 76, 68

Let the mark for the fifth exam be = x

Mean of the five exams = 70

Therefore,

By the problem,

[tex] = > \frac{65 + 80 + 76 + 68 + x}{5} = 70[/tex]

[tex] = > \frac{289 + x}{5} = 70[/tex]

=> 289 + x = 70 × 5

=> 289 + x = 350

=> x = 350 - 289

=> x = 61

Hence,

Marks of the fifth exam is 61 (Ans)

Cubic equation that has been transformed from the parent function with a vertical compression, reflected over the y-axis and shifted up.

Answers

Question is incomplete

Answer:

See Explanation

Step-by-step explanation:

Let the cubic function be

[tex]f(x) = (x,y)[/tex]

First transformation: Vertical compression

Let the scale factor be a where [tex]0 < |a| < 1[/tex]

The new function becomes:

[tex]f'(x) = (x,ay)[/tex]

Next: Reflection over y-axis

The rule is: [tex](x,y)=>(-x,y)[/tex]

The new function becomes:

[tex]f"(x) = (-x,ay)[/tex]

Lastly: Shifted up

Let the units up be b

The rule is: [tex](x,y)=>(x,y+b)[/tex]

So, the new function becomes:

[tex]f"'(x) = (-x,ay+b)[/tex]

Using the rules states above, assume the cubic function is:

[tex]f(x) = x^3[/tex]

Vertical compress [tex]f(x) = x^3[/tex] by [tex]\frac{1}{2}[/tex]

[tex]f'(x) = \frac{1}{2}x^3[/tex]

Reflect [tex]f'(x) = \frac{1}{2}x^3[/tex] over y-axis

Rule: [tex]f"(x)= f'(-x)[/tex]

Solving f'(-x)

[tex]f'(x) = \frac{1}{2}x^3[/tex]

[tex]f'(-x) = \frac{1}{2}(-x)^3[/tex]

[tex]f'(-x) = -\frac{1}{2}x^3[/tex]

So:

[tex]f"(x) = -\frac{1}{2}x^3[/tex]

Lastly: Shift [tex]f"(x) = -\frac{1}{2}x^3[/tex] by 3

Rule: [tex](x,y)=>(x,y+b)[/tex]

[tex]f'"(x) = f"(x + 3)[/tex]

Solving: f"(x + 3)

[tex]f"(x) = -\frac{1}{2}x^3[/tex]

Substitute x + 3 for x

[tex]f"(x + 3) = -\frac{1}{2}(x + 3)^3[/tex]

So:

[tex]f'"(x) = f"(x + 3)[/tex]

[tex]f"'(x) = -\frac{1}{2}(x + 3)^3[/tex]

Answers

Answer:

The probability of not spinning a 3 is [tex]\frac{8}{9}[/tex]

Step-by-step explanation:

The probability of spinning a 3 is 1/9. What is the probability of not spinning a 3?

Spinning a 3 and not spinning a 3 are complementary events, which means that the sum of their probabilities is decimal 1. So

[tex]\frac{1}{9} + p = 1[/tex]

[tex]p = 1 - \frac{1}{9} = \frac{9}{9} - \frac{1}{9} = \frac{8}{9}[/tex]

The probability of not spinning a 3 is [tex]\frac{8}{9}[/tex]
