Dan purchased a set of knitting needles for $11 and 6 identical packs of yarn. The total cost was $89.
How much did each pack of yarn cost?
Answer:
13$
Step-by-step explanation:
Dan purchased a set of knitting needles for $11 and 6 identical packs of yarn. The total cost was $89.
How muc[tex]rweds[/tex]h did each pack of yarn cost?
The total cost of each pack of yarn is $13.
What is a total cost?The total cost of an item is the sum of the cost of all items that are purchased. Total cost for more items can be found by multiplying the number of items and the cost of the individual item.
For the given situation,
There are two items purchased knitting needles and packs of yarn.
Cost of knitting needle = $11
Number of packs of yarn purchased = 6
Total cost = $89
Let the cost of yarn be x.
The cost of the yarn can be find by using the equation,
Total cost = Cost of knitting needle + (number of yarn purchased × x)
⇒ [tex]89=11+6x[/tex]
⇒ [tex]6x=78[/tex]
⇒ [tex]x=13[/tex]
Hence we can conclude that the cost of each pack of yarn is $13.

Answer:
sinA = 0.79 tanA = 1.3
Step-by-step explanation:
Step1:
Find the length of the line going through the middle from A to C by using pythagorean theorem.
a = 13
b = 12
c= ?
c = sqrt(a^2 + b^2)
c = sqrt(13^2 +12^2)
c = 17.69
Step 2:
Use pythagorean theorem again to find the length of the line going from A to D.
a = ?
b = 14
c = 17.69
c^2 = a^2 + b^2
Now solve for a.
a^2 = c^2 - b^2
a = sqrt(c^2 - b^2)
a = sqrt(17.69^2 - 14^2)
a = 10.81
Step 3:
Use trignometry to find the values of sinA and tanA
sinA = opposite/hypotenuse = 14/17.69 = 0.79
tanA = opposite/adjacent = 14/10.81 =1.3

Function h is nonlinear, and h(4) = 2. Which equation could represent function h ?
Answer:
C
Step-by-step explanation:
H(4) simply means that where there is X, it must be substituted by the value 4
So lets see step by step:
A. h(4)=2 (incorrect)(there is no X to substitute on the right side and it is stated that H is non linear. This 2 would mean that H is a straight line)
B. (4)^3 -4= 60 (incorrect as answer needs to be 2)
C. 2^4 - 14=2 (correct, as answer is 2 and equation is non linear)
D. 1/2 (4) +3 = 5 (incorrect)

x is the amount of lemonade Kayla sold
find least common denominator
1 3/12 = 8/12 + x
subtract 8/12 on both sides
15/12 - 8/12 = x
7/12 = x
7/12 = amount of lemonade Kayla sold
2/3 - 7/12 = how much more Ethan sold

Answer:
an = a(n-1) - 7

There are eleven people on a softball team and nine different positions. work through the questions to determine how many ways a coach can choose the players for the positions if amy does not want to pitch. if there are eleven people on the team and nine positions, how many total arrangements of the players can be made? if amy does not want to play pitcher, then there are now people available to pitch. assuming the pitcher has already been chosen, there are ten remaining players and remaining positions. how many ways are there to arrange the remaining players and positions?
Permutation helps us to know the number of ways an object can be arranged in a particular manner. The number of ways the remaining player can be arranged is 1,814,400.
What is Permutation?Permutation helps us to know the number of ways an object can be arranged in a particular manner. A permutation is denoted by 'P'.
[tex]^nP_r = \dfrac{n!}{(n-r)!}[/tex]
where,
n is the number of choices available,
r is the choices to be made.
Given that the team has 11 players while there are only 9 positions available, therefore, the number of ways the coach can choose 9 people and arrange them is,
[tex]^{11}P_9 = \dfrac{11!}{(11-9)!} = \dfrac{11!}{2!} = 19,958,400[/tex]
Now, since Amy does not want to be a pitcher, therefore, the number of ways the remaining people can be arranged in the place of the pitcher is 10. Also, the position remaining in the team is 8, while the number of people remaining is 10. Thus, the number of ways the remaining people can be arranged are,
[tex]\text{Number of ways}= ^{10}P_8 =\dfrac{10!}{(10-8)!} = 1,814,400[/tex]
Hence, the number of ways the remaining player can be arranged is 1,814,400.

centeral school is hosting a "central has talent" show they will award various prices for the best 3 acts in the show first place wins the most money, and each susequent place after 1st wins $50 less then the previous place. let x equal the amount of money first place wins what expressions represent the total amount of prize money.
Answer:
The expression represent the total amount of price money is 3x-150.
The expressions let X be the amount of money for first place. This means X-50 would be the amount of second place because each subsequent place after 1st wins $50 less than the previous place. Thirds, would be X-50-50 or X-100.
That is X = first place and each place after that is 50 less so 2nd place would be x - 50 and third place would be x - 100.
Thus the total amount of money would be all of the values combined which is
x + (x - 50) + (x - 100)
Combinimg the like terms
What is the combinimg the like terms?
To combine like terms, we have to add the coefficients and keep the variables the same. We add like terms to make one term.
x+x-50+x-100
3x-150
3x - 150
Therefore the option b is correct.
So the expression represent the total amount of price money is 3x-150.
