The company also discovered that it costs $25 to produce 2 camera cases, $59 to produce 4 camera cases and $305 to produce 10 camera cases . Find the total cost of producing 5 camera cases

Please help!!!

Answers

Answer:

Cost of 5 camera cases is $85.

Step-by-step explanation:

First we need to determine what type of function we're dealing with, is it linear, quadratic or exponential?  We can determine this by calculating the first difference.

We can translate the number of cameras to correspond to the x axis and cost to the y axis.  By doing this we can come up with the ordered pairs of (2,25), (4,59),(10,305).  Let's get the first two ordered pairs and calculate the first difference:

[tex]\frac{59-25}{4-2}=17[/tex]

And now the second and third value:

[tex]\frac{305-59}{10-4}=41[/tex]

Notice how these values do not match, this means that this function is not increasing at a constant rate meaning that this function is not linear.  Now let's calculate the second difference:

[tex]\frac{41-17}{10-2}=3[/tex]

This means our function is quadratic with a=3.  Remember that generally speaking a quadratic function is such that:

[tex]y=ax^2+bx+c[/tex]

Where a,b,c are coefficients and in this case a=3.  Now, let's solve for b and c values by using the coordinates given.  Let's use the coordinates (2,25) where x=2 and y=25 and so:

[tex]f(x)=ax^2+bx+c\\\\25=3(2)^2+b(2)+c\\25=3(4)+2b+c\\25=12+2b+c\\13=2b+c\\\\b=\frac{13-c}{2}[/tex]

Now let's solve for "c" by using different coordinates (4,59) where x=4 and y=59 and also use the "b" value that we calculated above and so:

[tex]f(x)=ax^2+bx+c\\\\59=3(4)^2+(\frac{13-c}{2})(4)+c\\59=48+\frac{52-4c}{2}+c\\11=\frac{52-4c+2c}{2}\\11=26-2c+c\\-15=-c\\\\c=15[/tex]

Now that we know the value of "c" we can use the equation for b to solve for b and so:

[tex]b=\frac{13-c}{2}=\frac{13-15}{2}\\\\b=-1[/tex]

So this means in the quadratic equation a=3, b=-1 and c=15 therefore by using the general equation of a quadratic function we obtain or final equation:

[tex]f(x)=ax^2+bx+c\\\\f(x)=3x^2-x+15[/tex]

Since we want to find the total cost of producing 5 camera cases x=5 and so:

[tex]f(x)=3x^2-x+15\\\\f(5)=3(5)^2-(5)+15\\f(5)=75-5+15\\\\f(5)=85[/tex]


And so the cost of 5 camera cases is $85.


Simplify the expression. 3x2 + x − x2 − 2x
A. 2x
B. 2x2 − x
C. 3x2 − 2x
D. 4x2 − 3x

Answers

Answer:

B. 2x^2 − x

Step-by-step explanation:

3x^2 + x − x^2 − 2x

We need to combine like terms

3x^2 -x^2+ x − 2x

2x^2 -x

The expression 3x² + x - x² - 2x simplifies to 2x² - x, which is Choice B.

To simplify the expression 3x² + x - x² - 2x, you can combine like terms. The equation has two terms involving x squared (x²) and two terms involving x to the first power.

Combine the x² terms: 3x² - x² = 2x².

Next, combine the x terms: x - 2x = -x.

Putting them together, the simplified expression is 2x² - x.

Therefore, the answer is Choice B: 2x² - x. This step-by-step process demonstrates the importance of combining like terms and simplifying expressions to arrive at the correct solution.

Chris needs $858 to buy a computer. She has already saved $575. She gets $15 an hour for babysitting and will babysit 12 hours in the next month. She can save &8 a week form her allowance. How many weeks of allowance will it take Chris to save enough to buy the computer?

Answers

Answer:

It will take Chris 13 weeks of allowance to save enough to buy the computer.

Step-by-step explanation:

Chris needs $858 to buy a computer.

She has already saved $575.

She gets $15 an hour for babysitting and will babysit 12 hours in the next month, then she will get for babysitting:

($15/hour)(12 hours)=$180

Then, Chris will need:

A=$858-$575-$180→A=$103

She can save &8 a week form her allowance, then she will need:

Number of weeks: n = $103 / ($8/week) → n=12.875 weeks

Rounding:

n=13 weeks


Chris will need 13 weeks of saving her allowance to have enough money to buy the computer.

Chris needs to save a total of $858 for a computer and has already saved $575.

To determine how many weeks she will need to save her allowance to purchase the computer, we must first calculate the additional amount she will earn from babysitting.

Chris earns $15 an hour for babysitting and will babysit for 12 hours in the next month, earning her an additional 15 x 12 = $180.

Adding this to her current savings of $575 gives us a total of $575 + $180 = $755.

The remaining amount needed to buy the computer is $858 - $755 = $103.

Since Chris saves $8 per week from her allowance, we divide the remaining amount by her weekly savings to find the number of weeks required: $103 / $8 = 12.875 weeks.

Since partial weeks of savings are not possible, we round up to the nearest whole number, which means Chris will need 13 weeks to save enough from her allowance to buy the computer.

2. Sally buys a hand bag. There was a discount of 30%. If Sally paid $20, what was the original price?

Answers

Answer:

the original price is $28.57

Step-by-step explanation:

If the discount is 30% then the amount paid is 70% of the original price. Sally paid $20, it is the discounted price, equivalent to 70%.


We need to divide $20 by 70% to get the original price or the 100%.


$20 / 70% = $28.57 original price.


Since the handbag was has discount of 30%, we multiply the original price with the 30% to get the discount value.


$28.57 * 30% = $8.57 discount


To check: deduct the discount from the original price to get the discounted price.


$28.57 - $8.57 = $20

James has a model helicopter. The model is 8 inches long and 7 inches wide. The actual helicopter is 56 inches long. What is the helicopters actual width, if we assume the models proportions are accurate?
A: 40 inches
B: 49 inches
C: 56 inches
D: 60 inches

Answers

Answer:

49 inches

Step-by-step explanation:

Write and solve an equation of ratios, as follows:

7 inches               x

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

8 inches        56 inches


Then (8 ")x = (7 ")(56 "), and

x = 392/8 inches = 49 inches.

The actual width of the helicopter is 49 inches.

The actual width is found to be 49 inches, which corresponds to answer choice B.

The question is asking us to determine the actual width of a helicopter given its scale model dimensions and the actual length. To solve the problem, we use the concept of ratios or proportions. The scale model is 8 inches long and 7 inches wide, and the actual helicopter is 56 inches long.

We set up a proportion to find the actual width:

Model length : Actual length = Model width : Actual width8 inches : 56 inches = 7 inches : x inches

To solve for x, we cross multiply:

8 * x = 56 * 7

x = (56 * 7) / 8

x = 392 / 8

x = 49 inches

Therefore, the correct answer is B: 49 inches, which is the actual width of the real helicopter.

An investor invested a total of ​$3 comma 500 in two mutual funds. One fund earned a 4​% profit while the other earned a 2​% profit. If the​ investor's total profit was ​$110​, how much was invested in each mutual​ fund

Answers

Answer:

$2000 invested in first fund

$1500 invested in second fund

Step-by-step explanation:

An investor invested a total of ​$3,500 in two mutual funds.

Let x be the amount invested in first fund

first fund earned a 4​% profit (4%= 0.04)

So interest is 0.04x for first fund

Let x be the amount invested in first fund

first fund earned a 4​% profit (4%= 0.04)

So interest is 0.04x for first fund

Let y be the amount invested in second fund

second fund earned a =2​% profit (2%= 0.02)

So interest is 0.02y for second fund

An investor invested a total of ​$3,500 in two mutual funds.

So x+y = 3500----> equation 1

y= 3500-x

the​ investor's total profit was ​$110

0.04x + 0.02y = 110----> equation 2

Plug in 3500 -x for y

0.04x + 0.02(3500-x) = 110

0.04x + 70 - 0.02x = 110

0.02x + 70 = 110

Subtract 70 onboth sides

0.02x = 40

Divide both sides by 0.02

x= 2000

y= 3500-x

so y= 3500 - 2000 = 1500

$2000 invested in first fund

$1500 invested in second fund

Answer:

[tex]y=-2cos (2(x+\pi ))-1[/tex]

Step-by-step explanation:

From the graph, we can see that y = -3 when x  = 0.

So to check whether which of the given options is the equation of the given graph, we will set our calculator to the radian mode and then plug the value of x as 0.

1. y = -2 cos (4(x + pi)) - 1 = -2 cos (4(0 + pi)) - 1  = 3

2. y = 2 cos(x + pi) = 2 cos(0 + pi) = -1

3. y = -2 cos (2(x + pi)) - 1 = -2 cos (2(x + pi)) - 1 = -3

Therefore, the equation of this graph is  y = -2 cos (2(x + pi)) - 1.



Rachel has 30 pounds of a mixture of candy that sells for $1.00/lb. If lollipops sell for $0.95/lb and caramel candies sell for $1.10/lb. How many pounds of lollipops are in the mixture?
Could I have an equation for the problem.
Thank you so Much!

Answers

Answer:

Twenty Pounds

Step-by-step explanation:

Equation #1:

30lbs x Mix Price = (Lollipop Lbs  x 0.95)  + (Caramel Lbs X 1.10)

Equation #2:

Lollipops Lbs + Caramel Lbs = 30 Lbs

Rearrange expressions to solve for different variables

EQ1:   Caramel Lbs = (30 - .95 Lollipop Lbs)/ 1.10      NOTE: (mix price = 1.00)

EQ2:  Lollipop Lbs = 30 - Caramel Lbs

Substitute formula 1 into formula 2

Lollipop Lbs = 30 - [(30 - .95 Lollipop Lbs)/1.10]

Distribute divisor

Lollipop Lbs  = 30 - 27.2727 + .8636 Lollipop Lbs

Collect terms

Lollipop Lbs  =  2.7273 + .8636 Lollipop Lbs

Remove .8336 Lollipops from both sides of the equation

.1364 Lollipop Lbs = 2.7273

Divide both sides by .1364   (Answer is  19.9949 which rounds to 20)

Lollipop Lbs =  20

PROOF:

30 = (20 x 0.95) + (10 x 1.10)

30 = 19 + 11

30 = 30   TRUE!


Final answer:

To determine the number of pounds of lollipops in the mixture, we can set up an equation with the total weight of the mixture and the weight of the lollipops. Solving the equation, we find that there are 15 pounds of lollipops in the mixture.

Explanation:

To solve this problem, we can set up an equation using the given information.

Let x represent the number of pounds of lollipops in the mixture.

Since Rachel has a total of 30 pounds of the mixture, we can write the equation: x + (30 - x) = 30

Simplifying the equation, we have: 2x = 30

Dividing both sides by 2, we find that x = 15.

Therefore, there are 15 pounds of lollipops in the mixture.

Step-by-step explanation:

Answer:

Not sure what your exact question is, but I'll make an assumption that you are asking for the percentages of each statistic. It's going to be:

30% pizza

50% chicken

20% hot dogs

Step-by-step explanation:

Because you have 20 members, to get a total percentage, I divided by 2 to get to 10, which is going to make it easier to determine the percentages.

Next, because you divided the total players by 2, you have to do the same for each of the votes as well. Six becomes three, 10 becomes 5, and the rest (which is four) becomes two.

Now, you need to multiply by 10 to get the exact percentage. 10 becomes 100%, and the same for all the other numbers.
