Answer:

-1x+10

Step-by-step explanation:

The equation that shows how the number of fluid ounces of nectar remaining (y) depends on the number of days since Logan filled it (x) is:

y = 10 - x.

The relationship between the number of fluid ounces of nectar remaining (y) and the number of days since Logan filled the hummingbird feeder (x) can be represented using a linear equation.

Initially, when Logan fills the hummingbird feeder to its capacity of 10 fluid ounces, the nectar remaining is 10 fluid ounces.

As each day passes, 1 fluid ounce of nectar is released.

Therefore, the equation that shows how the number of fluid ounces of nectar remaining (y) depends on the number of days since Logan filled it (x) is:  y = 10 - x.

Here's an explanation of each component of the equation:

y: This represents the number of fluid ounces of nectar remaining.

As the days pass, this value will decrease as nectar is released.

10: This is the initial amount of nectar in the feeder when Logan fills it to its capacity of 10 fluid ounces.

x: This represents the number of days that have passed since Logan filled the feeder.

Each day, the amount of nectar decreases by 1 fluid ounce, hence the subtraction of "x."

This equation forms a linear relationship where the nectar remaining decreases by 1 fluid ounce for each day that passes.

Answer:

1.25

Step-by-step explanation:

The answer in decimal is 1.25

35/28= 1.25

= 35 ÷ 28

by 1

=35 - 28 = 7

Introducing decimals

= 70 to 28

by 2

= 70 - 56 = 14

adding zero to 14

= 140 to 28

by 5

= 140 - 140 =0

the answer is 1.25

Simply stack the numbers (lining up the decimals) and add right to left.

[tex] {5}^{2} + {x}^{2} = {8}^{2} [/tex]

[tex]25 + {x}^{2} = 64[/tex]

Subtract both sides 25

Answer:

A=18km B=equation is 9t

Step-by-step explanation:

Here's how I found the answer!

A: Here is our current proportion:

9km

--------

1 hr

Here is what we want:

9km       xkm

------- = --------

1h            2h

Now, what did I do to 1 to get to 2? I multiplied by 2.

Since this is a ratio, it needs to be proportional.

So, we need to do the same thing for the numerator, 9.

9*2=18.

A=18km

B: This question is asking for an expression, which would be 9t. 9 is the amount he jogs per hour, and t is the hour that is unknown.

The distance travelled by Elliot's is 18 hours.

Given that, Elliot's jogging rate is 9 km/h.

The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.

a) The formula to find the distance is Distance = Speed × Time

= 9 × 2

= 18 hours

b) Distance = 9 × t

=9t hours

Therefore, the distance travelled by Elliot's is 18 hours.

Answer:

she will pay $19 for each day

Step-by-step explanation:

94-18=76

76÷4=19

The rental cost of each day Tara used the kayak is $19 if Tara stayed at the Merry Mountain campgrounds last weekend. She paid a rental fee to use a kayak for 4 days.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

Tara stayed at the Merry Mountain campgrounds last weekend. She paid a rental fee to use a kayak for 4 days.

Let x be the rental cost of each day Tara used the kayak.

4x + 18 = 94

4x = 94 - 18

4x = 76

x = 76/4

x = $19

Thus, the rental cost of each day Tara used the kayak is $19 if Tara stayed at the Merry Mountain campgrounds last weekend. She paid a rental fee to use a kayak for 4 days.

Using the binomial distribution, it is found that:

For each person, there are only two possible outcomes, either they prefer saving, or they prefer spending. The preferences of each person are independent of any other person, hence, the binomial distribution is used to solve this question.

Binomial probability distribution

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

The expected value is:

[tex]E(X) = np[/tex]

The standard deviation is:

[tex]\sqrt{V(X)} = \sqrt{np(1 - p)}[/tex]

In this problem:

Then:

[tex]E(X) = np = 4(0.6) = 2.4[/tex]

[tex]\sqrt{V(X)} = \sqrt{np(1 - p)} = \sqrt{2.4(0.6)(0.4)} = 0.76[/tex]

Answer:

Step-by-step explanation:

the rectangle = 12 * 5 = 60

plan A:

the triangle A with H = (13 - 5)/2 = 8/2 = 4

then triangle A = [tex]\frac{1}{2}[/tex] * 6 * 4 = 24/2 = 12

total triangles = 12 * 4 = 48

hexagon area = 60 + 48 = 108

plan B:

there 13 - 5 = 8

because there are identical triangles, so we can shape both of it being a rectangle with short line is 8/2 =4, and long line is 12

then we calculate that rectangle area = 12 * 4 = 48, then total of the hexagon = 60 + 48 = 108

Answer:

y^2 = 8x

or

x = 1/8 y^2.

Step-by-step explanation:

The general form for this type of parabola is

y^2 = 4ax where the focus is at (a, 0) and the directrix  is x = -a

So the equation is y^2 = 4*2x

[tex]\huge\boxed{4\dfrac{1}{2}:5\dfrac{2}{5}=5:6}[/tex]

Step-by-step explanation:

[tex]4\dfrac{1}{2}:5\dfrac{2}{5}[/tex]

we convert a mixed number to an improper fraction

[tex]4\dfrac{1}{2}=\dfrac{4\cdot2+1}{2}=\dfrac{9}{2}\\\\5\dfrac{2}{5}=\dfrac{5\cdot5+2}{5}=\dfrac{27}{5}[/tex]

Therefore

[tex]4\dfrac{1}{2}:5\dfrac{2}{5}=\dfrac{9}{2}:\dfrac{27}{5}=\dfrac{9\!\!\!\!\diagup^1}{2}\cdot\dfrac{5}{27\!\!\!\!\!\diagup_3}=\dfrac{1}{2}\cdot\dfrac{5}{3}=\dfrac{1\cdot5}{2\cdot3}=\dfrac{5}{6}=5:6[/tex]

The ratio 4 1/5 to 5 2/5 is equivalent to the simplified fraction 7/9.

To write the ratio 4 1/5 to 5 2/5 as a simplified fraction, we need to convert both mixed numbers to improper fractions and then find their ratio.

Step 1: Convert the mixed numbers to improper fractions:

4 1/5 = (4 * 5 + 1) / 5 = 21 / 5

5 2/5 = (5 * 5 + 2) / 5 = 27 / 5

Step 2: Find the ratio by dividing the first fraction by the second fraction:

Ratio = (21 / 5) / (27 / 5)

Step 3: To divide by a fraction, multiply by its reciprocal:

Ratio = (21 / 5) * (5 / 27)

Step 4: Simplify the fraction:

Ratio = (21 * 5) / (5 * 27)

Ratio = 105 / 135

Step 5: Simplify the fraction further by dividing both the numerator and denominator by their greatest common divisor, which is 15:

Ratio = (105 / 15) / (135 / 15)

Ratio = 7 / 9
