Tom is ordering 5 bags of cat food from Canada. Each bag has a mass of 6 kg . To determine the shipping costs, Tom needs to know the total weight in pounds. What is the weight of the cat food in pounds? Use 1kg= 2.2 lb and do not round any computations.
Answer:
6* 2.2lb = 13.2 lb
Step-by-step explanation:
If 1 bag weights 2.2lb than 6 bags will weight 6 times more or:
2.2 lb * 6 = 13.2 lb
We can use the provided conversion factor, which states that 1 kg is equal to 2.2 pounds, to determine the weight of the cat food in pounds.
Since each bag of cat food weighs 6 kg, we can calculate the weight of 5 bags as follows.
5 bags of 6 kg each equal the total weight = 30 kg.
Now, we can convert the total weight from kilograms to pounds using the conversion factor:
Total weight multiplied by the conversion factor equals total weight in pounds.
= 30 kg x 0.2 lb/kg.
= 66 lbs.
Consequently, the cat food has a 66-pound weight when measured in pounds.

Table C shows the sample space for choosing 2 marbles from the bag with replacement. The probabity and there are 25 possible pairs.
The sample space for choosing 2 marbles from the bag with replacement consists of all possible pairs of marbles that can be chosen, where the order in which they are chosen does not matter.
Since there are 5 marbles in the bag and we are choosing 2 of them, there are 5 choices for the first marble and 5 choices for the second marble, for a total of [tex]5*5 = 25[/tex] possible pairs.
Table C shows the sample space for choosing 2 marbles from the bag with replacement. Each row and column in the table represents a different marble that can be chosen, and each cell represents a pair of marbles that can be chosen.
For example, the cell in row 2 and column 3 represents the pair of marbles consisting of the red marble and the clear marble. Tables A and B show the sample space for choosing 2 marbles from the bag without replacement. In this case, the order in which the marbles are chosen does matter, and each marble can only be chosen once.

Kyle's current credit card balance is $3,109.87 with a minimum payment of $159.00. Over the next month he spends $532.42. If the APR is 27.99% (billed monthly), what will Kyle's new balance be, with interest? (4 points) $3,404.65 $3,564.54 $3,606.84 $3,789.03
Answer:
(b) $3564.54
Step-by-step explanation:
You want the new balance showing on a credit card statement if the APR is 27.99%, the old balance is $3109.87, a payment of $159 was made, and purchases were made totaling $532.42.
SubtotalApparently, the new balance is computed by subtracting payments, and adding new charges to the old balance, then computing and adding the finance charge on this sum.
balance before finance charge: $3109.87 -159.00 +532.42 = $3483.29
Finance chargeThe finance charge is 1 month's interest at the annual rate:
I = Prt = $3483.29×0.2799×(1/12) = $81.25
New BalanceThe new balance is the subtotal above, with the finance charge added:
new balance = $3483.29 +81.25 = $3564.54
Kyle's new balance will be $3564.54.
__
Additional comment
This is a very expensive credit card. Not only is the interest rate of 27.99% very high, but also finance charges are charged on new purchase in the month they are purchased.
Some cards these days have interest rates of 12.75% or lower, with no finance charge for purchases made during the month. Some cards offer a rebate of up to 1.5% of purchases, so a net "negative" finance charge if you pay off the card every month.

Domain: {-15, 0, 9, 33, 44, 45}
Range: {15, 21, 33, 46, 57, 97}
Step-by-step explanation:The domain and range describe the x and y-values of a function.
Domain
The domain of a function shows the x-values covered by a function. Since the function cannot be proved to be continuous, we have to list the domain as a discrete list of values. We cannot say that the values between the listed x-values are a part of the domain. Any x-value included in the function is a part of the domain. As stated in the question, we should list our answer as an ordered list with braces.
Domain: {-15, 0, 9, 33, 44, 45}Range
The range of a function shows the y-values covered by the function. Similar to the domain, we cannot assume that the y-values between those listed are included in the range. This means that the range will also be a list of values. Range and domain should be listed from least to greatest. So, we can create a list of all the y-values in numerical order.

Carter is going to invest in an account paying an interest rate of 4.3% compounded daily. How much would Carter need to invest, to the nearest ten dollars, for the value of the account to reach $174,000 in 19 years?
Carter would need to invest approximately $76,869.06 to reach a value of $174,000 in 19 years with a 4.3% annual interest rate compounded daily.
What is the principal that needs to be invested?The formula accrued amount in a compounded interest is expressed as;
[tex]A = P( 1 + \frac{r}{n})^{(nt)}[/tex]
Where A is accrued amount, P is principal, r is interest rate and t is time.
Given that:
Accrued amount A = $174,000
Compounded daily n = 365
Time t = 19 years
Interest rate r = 4.3%
Principal P = ?
First, convert R as a percent to r as a decimal
r = R/100
r = 4.3/100
r = 0.043
Plug these values into the above formula and solve for principal P.
[tex]A = P( 1 + \frac{r}{n})^{(nt)}\\\\A = 174,000( 1 + \frac{0.043}{365})^{(365\ *\ 19)}\\\\A = \$ 76,869.06[/tex]
Therefore, the principal that needs to invested is $76,869.06.

The formula for the surface area of a cylinder SA= 2mth + 2rr² is 525 cm².
To find the surface area of the cylindrical can, we need to use the formula:
SA = 2π[tex]r^2[/tex]+ 2πrh
where r is the radius of the circular base of the can, h is the height of the can, and π is a mathematical constant approximately equal to 3.14.
From the given dimensions, we know that the radius of the can is 4 cm. However, we do not have the height of the can. Therefore, we cannot accurately calculate the surface area of the can.
Based on the answer choices provided, we can approximate the surface area of the can by using the given value of r = 4 cm and an estimated value for the height.
For example, if we assume the height of the can is approximately 10 cm, then we can use the formula to calculate the surface area:
SA = 2π([tex]4^2[/tex]) + 2π(4)(10)
SA = 100.48 + 251.2
SA ≈ 351.68 [tex]cm^2[/tex]

what is trigonometry ratio and if tan
1) sin θ + tan θ is equal to 5/6. 2) sin θ is 5/12. 3) sec θ + cosecc^2 θ = 12/√119 + 144/25 4) cot θ + sin θ is equal to 169/60.
How to answer the aforementioned question1) To find sin θ + tan θ, we need to find the value of sin θ. Using the identity tan θ = sin θ / cos θ, we can rewrite tan θ as sin θ / cos θ.
tan θ = 5/12 = sin θ / cos θ
Since we are given that 0 < θ < 90, both sin θ and cos θ are positive.
Using the Pythagorean identity[tex]{sin^2}[/tex] θ + [tex]cos^2[/tex] θ = 1, we can solve for cos θ:
[tex]cos^2[/tex] θ = 1 - sin^2 θ
[tex]cos^2[/tex] θ = [tex]1 - (5/12)^2[/tex]
[tex]cos^2[/tex]θ = 1 - 25/144
[tex]cos^2[/tex] θ = 119/144
cos θ = √(119/144)
cos θ = √119/12
Now, we can find sin θ using the relationship [tex]sin^2[/tex] θ + [tex]cos^2[/tex]θ = 1:
[tex]sin^2[/tex] θ = 1 - [tex]cos^2[/tex] θ
[tex]sin^2[/tex]θ = 1 - (119/144)
[tex]sin^2[/tex]θ = 25/144
sin θ = √(25/144)
sin θ = 5/12
Finally, we can substitute the values of sin θ and tan θ into the expression sin θ + tan θ:
sin θ + tan θ = (5/12) + (5/12) = 10/12 = 5/6
Therefore, sin θ + tan θ is equal to 5/6.
2) The value of sin θ is already calculated as 5/12.
3) To find sec θ + [tex]csc^2[/tex] θ, we need to find the values of sec θ and csc θ.
Since sec θ is the reciprocal of cos θ, we can calculate sec θ as:
sec θ = 1/cos θ = 1/(√119/12) = 12/√119
csc θ is the reciprocal of sin θ, so:
csc θ = 1/sin θ = 1/(5/12) = 12/5
Now, we can substitute these values into the expression sec θ + [tex]csc^2[/tex]θ:
sec θ + [tex]csc^2[/tex]θ = (12/√119) + [tex](12/5)^2[/tex]= 12/√119 + 144/25
4) To find cot θ + sin θ, we need to calculate the value of cot θ.
cot θ is the reciprocal of tan θ, so:
cot θ = 1/tan θ = 1/(5/12) = 12/5
Now, we can substitute the values of cot θ and sin θ into the expression cot θ + sin θ:
cot θ + sin θ = 12/5 + 5/12
To add these fractions, we need a common denominator:
cot θ + sin θ = (12/5)(12/12) + (5/12)(5/5)
= 144/60 + 25/60
= 169/60
Therefore, cot θ + sin θ is equal to 169/60.

μY = 19.5 + 555
μY = 574.5
Therefore, the mean score of a random student (YY) is 574.5.
Standard Deviation of YY:
The standard deviation of YY, denoted as σY, can be calculated using the standard deviation of XX (σX) and the scoring scheme:
σY = σX * 10
Substituting the value of σX from the given information:
σY = 0.8 * 10
σY = 8
Therefore, the standard deviation of the random student's score (YY) is 8.

Please help I am struggling thank you, have a great day
Answer:
24
Step-by-step explanation:
For this problem, substitute the value -3 for x and solve. It would look like this:
[tex]4(-3)^2+2(-3)-6[/tex]
Using the order of operations (PEMDAS) we solve the exponent first.
[tex]-3^2=9[/tex]
Then solve the multiplication parts.
[tex]4(9)+2(-3)-6\\4*9=36[/tex]and [tex]2*(-3)=-6[/tex]
Finally subtract to get the answer.
[tex]36-6-6=24[/tex]
The triangle below is isosceles. Find the length of side x to the nearest tenth.
Answer: x=15.6
Step-by-step explanation:
An isosceles triangle has two congruent sides. (1 pair). So, the other side (not x) must equal 11.
Using the Pythagorean Theorem; a^2+b^2=c^2, you can substitute the values in as follows
11^1+11^2=x^2
121+121=x^2
242=x^2
15.55634918610405=x

Tyrell is traveling to Chicago, Illinois. He takes a cab service from the airport to his hotel. The table shows the linear relationship between the number of miles the cab travels, x, and the total fee, y.
Cab Fare
Number of Miles Total Fee
2 $13.00
5 $17.50
7 $20.50
10 $25.00
15 $32.50
What does the y-intercept mean in this situation?
For every additional mile the cab travels, the total fee increases by $10.00.
For every additional mile the cab travels, the total fee increases by $1.50.
When the cab travels 0 miles, the total fee will be $1.50.
When the cab travels 0 miles, the total fee will be $10.00.
Answer:
When the cab travels 0 miles, the total fee will be $10.00.
Step-by-step explanation:
We Know
2 miles = $13.00
5 miles = $17.50
3 miles = 17.50 - 13.00 = $4.50
1 mile = 4.50 / 3 = $1.50
So, for every 1-mile go, the cost is increasing by $1.50; this is the slope.
What does the y-intercept mean in this situation?
It is the total fee that Tyrell pays when the cab goes 0 miles (when he first steps in the cap).
So, the answer is D. When the cab travels 0 miles, the total fee will be $10.00.
Suppose theta is an angle in the third quadrant and cos theta = 5/7. What is the value of sin(theta)
3√8
√24
24
2√12
The value of sinθ is √24/7 meanwhile the correct answer is not in the option provided or perhaps option (b) is meant to be √24/7 instead.
Understanding Quadrant in TrigonometryIn the third quadrant, both the x-coordinate (cosine) and the y-coordinate (sine) of the angle are negative.
Given that
cosθ = 5/7
we can determine the value of sinθ using the Pythagorean identity:
sin²θ + cos²θ = 1
sin²θ + (5/7)² = 1
sin²θ + 25/49 = 1
Now, let's solve for sinθ:
sin²θ = 1 - 25/49
sin²θ = 49/49 - 25/49
sin²θ = 24/49
Taking the square root of both sides, we find:
sinθ = √(24/49)
Simplifying further:
sinθ = √24 / √49
sinθ = √24 / 7
