The equation 9t = 27.99 models a constant rate situation. Drag and drop the value of 5t in the box. 5t = 3.11 15.55 18.99 36.99

Answers

Answer 1
5t = 15.55. Here's why:

Since in the equation 9t = 27.99 is basically multiply two numbers to get a product, divide 27.99 by 9:

27.99/9 = 3.11

3.11 is the value of t. So now that we've found the value of t, plug it into the equation 5t like so:

5*3.11 = 15.55

I hope this helped you out! :)
Answer 2
One way to do this would be to calculate t = 27.99/9.

Then 5t would be 5(27.99 / 9).

At the store deli, Rita spent $13.45 on 5 pounds of cheese. How much would it cost to buy 2 pounds of cheese?

Answers

Let x be he price of 2 pound of cheese. Then:
13.45/5 = x/2
x = 13.45*2/5
x = 5.38
The answer will be $5.38

Answer:

The cost would be $ 5.38.

Step-by-step explanation:

Given,

The price of 5 pounds of cheese = $ 13.45,

So, the price of 1 pounds of cheese = [tex]\frac{\text{Price of }5\text{ pounds of cheese}}{5}[/tex]

[tex]=\frac{13.45}{5}[/tex]

[tex]=\$ 2.69[/tex]

Thus, the price of 2 pounds of cheese = 2 × price of each pound of cheese

= 2 × 2.69

Niko uses 12 marshmallows and 8 graham crackers to make 4 s'mores. Drag marshmallows and graham crackers into the box to show how many Niko needs to make 3 s'mores.

Answers

 6 graham crackers and 9 marshmallows. 

Answer: Niko needs 9 marshmallows and 6 graham crackers to make 3 s'mores.


Step-by-step explanation:

Let x be the number of marshmallows , y be the number of graham crackers and z be the number of s'mores.

Then according to given question

Niko uses 12 marshmallows and 8 graham crackers to make 4 s'mores

gives the equation 12x+8y=4z

If we divide whole equation by 4 , we get the quantity of x and y to make z such that

[tex]\frac{1}{4}(12x+8y)=\frac{1}{4}(4z)\\\Rightarrow3x+2y=z[/tex]

Now to make 3 s'mores, we need to multiply the equation by 3 such that

[tex]3\times(3x+2y)=3\times\ z\\\Rightarrow\ 9x+6y=3z[/tex]

Thus Niko needs 9 marshmallows and 6 graham crackers to make 3 s'mores.


For a closed cylinder with radius r ⁢ cm and height h ⁢ cm, find the dimensions giving the minimum surface area, given that the volume is 40 cm3.

Answers

Final answer:

The dimensions that give the minimum surface area are a radius of approximately 2.83 cm and a height of approximately 0.64 cm.

Explanation:

To find the dimensions of the closed cylinder that give the minimum surface area, we need to express the surface area of the cylinder in terms of one variable.

Let's use the radius, r, as the variable.

The surface area of a closed cylinder is given by the formula: A = 2πr² + 2πrh, where h is the height of the cylinder.

Since we are given that the volume of the cylinder is 40 cm³, we can use the formula for the volume of a cylinder to express h in terms of r: V = πr²h = 40 cm³.

Substituting this expression for h in terms of r into the surface area formula, we get:

A = 2πr² + 2πr(40 / (πr²)) = 2πr² + (80 / r).

To find the dimensions that give the minimum surface area, we need to find the value of r that minimizes A.

To do this, we take the derivative of A with respect to r and set it equal to zero:

A' = 4πr - (80 / r²) = 0. Solving this equation, we find that r = √(20/π) ≈ 2.83 cm.

So, the radius that gives the minimum surface area is approximately 2.83 cm.

We can then use the volume formula to find the corresponding height: h = 40 / (π(2.83)²) ≈ 0.64 cm.

Therefore, the dimensions giving the minimum surface area are a radius of approximately 2.83 cm and a height of approximately 0.64 cm.

Find two numbers whose sum is 23 and whose product is a maximum.

Answers

Let x = the first numberLet y = the second number x + y = 23                    eq1       y = 23- x 
xy = Product                 eq2

Substitute eq1 into eq2.  Lets get eq2 in terms of x.  

Product = x(23 - x)Product = - x2 + 23x
 
we must find the vertex has coordinate (h, k). h = -b / 2a  where:a = -1b = 23
h= -23  / -2  =  11.5 

 x = 11.5   


Substitute this value of x into eq1 to find y. y = 23 - xy = 23 - 11.5y = 11.5

The two numbers that will give the largest product possible are 11.5 and 11.5.

The unknown numbers are 11.5 and 11.5

Let the unknown numbers be x and y

If the sum of the numbers is 23, hence;

x +  y = 23

x = 23 - y ............. 1

If the product is at maximum, hence;

xy = maximum ......... 2

Substitute equation 1 into 2

(23 - y )y = maximum

23y - y² = maximum

maximum = -y² + 23y

A(y) =  -y² + 23y

Since the product A(y) is at maximum, hence dA(y)/dy = 0 as shown:

dA(y)/dy= -2y + 23 = 0

-2y + 23 = 0

2y = 23

y = 23/2

y = 11.5

Since x + y = 23

x = 23 - y

x = 23 - 11.5

x = 11.5

Hence the unknown numbers are 11.5 and 11.5

A fair die is rolled 8 times.
a. what is the probability that the die comes up 6 exactly twice?

Answers

P(first 2 rolls = 6 and rest not 6)  = 1/6 * 1/6 * (5/6)^6 =   0.00930272

there are 8C2 ways  of obtaining  exactly 2 6's in 8 throws = 28 ways

so required probability is 0.00930272 * 28 =  0.26  to nearest hundredth

The probability of rolling a 6 exactly twice in 8 rolls of a fair die is approximately 33.5%.

The situation describes a binomial distribution where we have:

n = 8 (number of trials)k = 2 (number of successes, i.e., rolling a 6)p = 1/6 (probability of success on a single trial)

The binomial probability formula is given by:

[tex]P(X = k) = \binom{n}{k} \times p^k \times (1-p)^{n-k}[/tex]

First, calculate (n choose k) which is given by:

[tex]\binom{n}{k}= n! / [k! \times (n-k)!][/tex]

For our problem:

[tex]\binom{n}{k} = 8! / [2! \times (8-2)!] = 28[/tex]

Next, calculate the probability:

[tex]P(X = 2) = 28 \times (1/6)^2 \times (5/6)^6[/tex]

Evaluating the above:

P(X = 2) = [tex]28 \times (1/36) \times (15625/46656)[/tex] ≈ 0.335

Therefore, the probability that the die comes up a 6 exactly twice in 8 rolls is approximately 0.335 or 33.5%.

Step-by-step explanation:

Jim worked 40 regular hours last week, plus 8 overtime hours at the time and a half rate.

This means if he is paid $ x per hour working in regular hours.

Then he will be paid $ (1.5x) per hour working overtime.

( Since it is given that: he is paid time and a half rate for overtime)

Now, his gross pay is: $ 1248

i.e.

Amount working at regular hours for 40 hours+ Amount obtained for working 8 hours overtime= $ 1248

i.e.

40x+8(1.5x)=1248

i.e.

40x+12x=1248

i.e.

52x=1248

i.e.

x=24

Yeah it does. Just up the equation. 7/9=42/54 and cross multiply so 7x54=378 and 9x42=378.
Another way I did it was that I divided 9/7 to get 1.2857. I tried the same to 54/42 and I got the same answer. I then used 1.2857 to multiply that by 7 and it ended up giving me 9 and I used that to multiply it by 42 as well to get 54.
Final answer:

The rates of 7 inches per 9 hours and 42 inches per 54 hours do form a proportion, as demonstrated by cross-multiplying the two ratios which resulted in equal cross products (378 inch-hours on both sides).

Explanation:

To determine if the two rates form a proportion, we need to compare the ratios of inches to hours for both scenarios. For the first rate, we have 7 inches in 9 hours, and for the second rate, we have 42 inches in 54 hours. A proper proportion exists when two ratios are equivalent.

Let's set up our two ratios:

First ratio: ​7 inches / 9 hoursSecond ratio: 42 inches / 54 hours

Now, we will test if these ratios form a proportion by creating a fraction out of each ratio and then cross-multiplying.

(7 inches / 9 hours) = (42 inches / 54 hours)

Cross multiply:

7 inches * 54 hours = 378 inch-hours

42 inches * 9 hours = 378 inch-hours

Since the cross products are equal, the two rates indeed form a proportion.

Step-by-step explanation:

To find the factored form of [tex]4a^3b^5-16a^5b^2+12a^2b^3[/tex] you must:

Apply exponent rule: [tex]a^{b+c}=a^ba^c[/tex]

[tex]a^2b^3=a^2b^2b,\:a^5b^2=a^2a^3b^2,\:a^3b^5=a^2ab^2b^3[/tex]

Which investment has the least amount of risk? standard deviation = $450, expected return = $4,500 standard deviation = $600, expected return = $400 standard deviation = $500, expected return = $800 standard deviation = $400, expected return = $5,000?

Answers

The investment with the highest expected return to standard deviation ratio is the investment with the least risk.

Investment 1: standard deviation = $450, expected return = $4,500
expected return to standard deviation ratio = 4500 / 450 = 10

Investment 2: standard deviation = $600, expected return = $400
expected return to standard deviation ratio = 400 / 600 = 0.67

Investment 3: standard deviation = $500, expected return = $800
expected return to standard deviation ratio = 800 / 500 = 1.6

Investment 4: standard deviation = $400, expected return = $5,000
expected return to standard deviation ratio = 5000 / 400 = 12.5

Therefore, the investment that has the least amount of risk is the invetment with standard deviation = $400, expected return = $5,000
