Answer:60, 6.75

Step-by-step explanation:

To solve the first prompt, we must create an equality statement.

[tex]\frac{10}{45}=\frac{x}{270}[/tex] X being the distance he can go in 4.5 hours.

In order to have came up with 270, we needed to take 4.5 hours and turn it into a measure of minutes to correspond to the minute value of 45.

This is found by multiplying 4.5 by 60.

Now that we have this done, we can cross multiply the equality statement.

[tex]10\cdot270=45x[/tex]

Simplify the first side

[tex]2700=45x[/tex]

Divide both sides by 45

[tex]\frac{2700}{45}=\frac{45x}{45}[/tex]

[tex]60=x[/tex]

This means that Jacob can bike 60 miles in 4.5 hours.

For the second prompt, we need to find how long it would take for him to bike 90 miles given the amount of time it took for him to bike 10 miles.

We can use an equality statement like this:

[tex]\frac{45}{10}=\frac{x}{90}[/tex]

Now we cross multiply:

[tex]45\cdot90=10\cdot x[/tex]

Simplify:

[tex]4050=10x[/tex]

Now we can divide both sides by 10.

[tex]\frac{4050}{10}=\frac{10x}{10}[/tex]

[tex]405=x[/tex]

This means that it would take Jacob 405 MINUTES to bike 90 miles.

To turn this into a measure of hours, we need to divide 405 by 60, which comes out to 6.75.

It would take Jacob 6.75 hours to bike 90 miles.

The decision meets each of the criteria by: Buying 500 popsicles at $0.50 each and 200 ice cream sandwiches at $1.50 each enables the purchase of 700 frozen delights within the $400 budget and satisfies the objective of producing at least $800 in profit.

I have made the decision to buy 500 popsicles at $0.50 each and 200 ice cream sandwiches at $1.50 each in order to fulfil the requirement of buying 700 frozen delights at a price of no more than $400.

Cost of purchasing 500 popsicles = (500 * $0.50)

Cost of purchasing 500 popsicles = $250

Cost of purchasing 200 ice cream sandwiches =(200 * $1.50)

Cost of purchasing 200 ice cream sandwiches  = $300

So, Total cost of purchasing all 700 frozen treats is $550 ($250 + $300) which is within the budget of $400.

I intend to sell the popsicles for $1.50 each and the ice cream sandwiches for $3.00 each in order to meet the requirement of turning a profit of at least $800. This would bring in $1350 in income for the ice cream sandwiches and $750 for the popsicles (500 * $1.50 and 200 * $3.00 respectively).

The objective of producing a profit of at least $800 is met after deducting the expense of buying the frozen treats from the overall income.

Net profit =($1350 - $550)

Net profit = $800

Therefore purchasing  500 popsicles at $0.50 each and 200 ice cream sandwiches at $1.50 each satisfies the objective of producing at least $800 in profit.

Answer:

-7≤y≤2

Step-by-step explanation:

The range measures the highest and lowest numbers up and down on the y-axis for a line. In order to determine range, start with the smallest number (the farthest place the line touches going down) then write less than or equal to. This is because the two dots are closed, meaning they include what the line touches. Afterward, add another less than or equal to, and then add the biggest number (the highest place the line touches going up). The range basically gives you your boundaries, and tells you how high or low the line you are describing is. And after that, you're done!

This capital gain  problem that can be modelled using this equation is one that relates to the price of a stock or share.

It can be writen as follows.....

Suppose that one purchased 900 shares of a stock at a price of $  12.55 per share .

After a year, the stock price rose to $ 13.25 per share, but you sold the shares at a price of $8. 14 per share due to financial difficulties.

You also incurred a transaction cost of $25.

What is the capital gain or loss made on the stock?

given the above question, if we solved for for the problem, we would get....

Solving for x, we get:

((900 )(x )-(900 )(x)(.01))-(900) (x-4)  +25)

= 15,740

Simplifying this expression, we get:

(0.99900x) - (36 x 900) + 25

= 15,740

0.99900 x = 15,655

x = 17.39

The data value corresponding to z = 0.55 is approximately 87.6075.

To find the data value corresponding to a given z-score, we need to use the formula:

z = (x - μ) / σ

where z is the standard score, x is the data value, μ is the mean, and σ is the standard deviation.

Rearranging this formula, we get:

x = z * σ + μ

Substituting the given values, we get:

x = 0.55 * 4.85 + 85.3

x = 87.6075

Therefore, the data value corresponding to z = 0.55 is approximately 87.6075.

Answer:

The answer is A.

A graph passes through a point if its equation is equal to the coordinate of this point. In this exemple:

5x+4y=8

we replace the variables with 4 and -3 (x with 4 and y with -3):

5(4)+4(-3)=8

20-12=8

8=8 so it passes.

NOW , for the slope:

slope = - 5/4 ( the equation is 5x+4y=8 , the cartesian equation is 5x+4y-8=0. THE cartesian equation with variables is ax+by+c=0) NOW this is linked with the slope bcz the slope is linked to the director vector (-b;a) that gives (-4;5), this is the director vector's formula that we're going to call U. THEN with this formula you get the slope: Y of U / X of U = 5/-4 = - 5/4 (bcz you dont leave the denominator with a negative sign).

Answer:

12 - 6n

Step-by-step explanation:

As this sequence decreases, rather than increases, this tell us that the nth term of this sequence will be minus. The difference from 6 and 0 is 6, telling us that the decrease is by 6 each time. So now we know the nth term of this sequence; -6n, but the sequence of -6n is -6,-12,-18 and so on. We need 6,0,-6. To find out the second part of the nth term find the difference from the sequence given and the sequence of -6n. The difference is 12 because the 6--6 = 12. So now we get the nth term of the sequence -6n + 12 which is written as 12-6n.  

The minimum height the second beaker must be so it does not overflow is 9.55 inches.

Given that a beaker has a radius of 1.8 inches and height of 4.6 inches. we need to find the height of another beaker which has the radius of 1.25 in and has same volume,

Volume of a cylinder = π × radius² × height

= 3.14 × 1.8² × 4.6

= 46.8 in³

Now, the second beaker =

46.8 = 3.14 × 1.25² × h

h = 46.8 / 3.14 × 1.25²

h = 9.55

The total gain at the end of the second year for both accounts combined is $509.09.

We have,

Amount saved = $8500

40% of 8500 is saved in saving account = 0.4 x 8500 = $3400

Remainder amount in stock plan = 8500 - 3400 = 5100

Working for savings plan

A = P(1 + r/n[tex])^{nt[/tex]

A = 3400(1 + 0.042/1)²

A = $3691.60

So, we gain = 3691.6 - 3400 = $291.6

Working for stock plan:  

The stock plan decreases 3% in the first year

= 5100 x 0.97

= $4947

and increases 7.5% in the second year.

= 4947 x 1.75

= $5318.03

So, we gain = 5318.03 - 5100 = $218.03

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

1. x⁴ + 5x³ + 7x² -3x - 10 = 0

= (x-1)(x+2)(x² + 4x + 5)

Thus, the rational roots are 1 and -2.

2. 3x² -4 = - x⁴

x⁴ + 3x² -4 = 0

(x-1)(x+1)(x² + 4) =0

Thus, the zeroes are 1, -1, -2i, +2i.

3. We can write the zeroes as

p(x)=(x-1)(x-2)(x+2)(x+3).

So, p(x) = x⁴ + 2x³ -7x² -8x +12

4. x³ -3x² +4x- 12=0

(x-3)(x²+4) =0

x= 3, -2i, 3i

5.  x= 1,2,4,6,8,10,11

y= 0,-1,0,4,8,9,8

y = -1(x-1)

y + x +1=0

6. x= 2,5,12,20 and y= 30,12,5,3

k = 30/2

k = 15

So, the relationship is y= 15x.

7. cn = constant(k)
