In a park for 6 people the ticket cost $39. How many dollar does it cost for 9 people

Answers

$ 58.50

Step-by-step explanation:

because 39 Divided by 6 is 6.5 and 6.5 × 9 it's 58 50

•ANSWER•
$58.50

•EXPLANATION•
The first thing you have to do is divide 39 by 6 to see how much it would cost for 1 person. For 1 person it cost $6.50 then you multiply by 9 because you are trying to figure out how much it cost for 9 people not 1. You will get $58.50.

1(whole number) 4/6 (fraction) + 2(Whole number) 1/4 (fraction)

Answers

Answer:

Step-by-step explanation:

Answer:

answer is 3 11/12

Step-by-step explanation:

1 4/6 =10/6

2 1/4=9/4

when adding fractions that are do not share a common denominatour you have to find a common multiple

which in this case is 12

so 9/4 timesed the top and the bottom by 3 gives you 27/12

and 10/6 timesed the top and bottom by 2 gives you 20/12 and then you add the the nominators which is 20+27 which then gives you 47/12 and then to change it back to mixed fraction you will get 3 (wholes) and 11/12 (fraction)

what is the coordinate for
x = 5
2x + y = 10

x =? y =?

Answers

Step-by-step explanation:

x = 5

then

2x + y = 10

2 * 5 + y = 10

y = 10 - 10

y = 0

x = 5, y = 0

Hope it will help :)

Answer:

x=5

Step-by-step explanation:

so it would be 2(5) since 5 is x and that would be 10+y=10.

soo if you're trying to find what + what = 10 it would be zero.

10+0=10.

What is the value of c?

Answers

the answer is c=8

hope that helps lolol

Answer: c=8

Step-by-step explanation: All three angles in a triangle add up to 180 degrees so 9c+66+42=180. First add 66 and 42 which is 108, so now you have 9c+108=180. Then subtract 108 from both sides to get 9c=72. Finally, divide each side by 9 to isolate c and you get c=8

If f(x) = 2x2 – 3x + 4, then f(x + 3) is equal to

Answers

If function f(x) = 2x2 – 3x + 4, then f(x + 3) is equal to f(x+3)= 2x^2 +9x +13.

Degree of polynomial is two so it will have only two solution

f(a)=0 if x=a

f(b)=0 if x=b

so put X=x+3

we will get

2[x+3]^2 - 3[x+3] + 4 = 2x^2 +9x +13

so if f(x+3)= 2x^2 +9x +13

The highest degree of a polynomial's monomials with non-zero coefficients is referred to as the polynomial's degree in mathematics. A term's degree is a non-negative integer and is calculated by adding the exponents of all the variables that occur in it.

The highest exponent of a polynomial's variable is referred to as the polynomial's degree. • A polynomial of degree zero is a constant polynomial. Zero polynomial is the name given to the constant polynomial f(x) = 0.

we want to find x not x² so we square root x² and that gives us the value for x

Hoffman Company manufactures car seats in its Miami plant. Each car seat passes through the assembly department and the testing department. This problem focuses on the assembly department. The process- costing system at Hoffman Company has a single direct- cost category (direct materials) and a single indirect- cost category (conversion costs). Direct materials are added at the beginning of the process. Conversion costs are added evenly during the process. When the assembly department finishes work on each car seat, it is immediately transferred to testing. Hoffman Company uses the weighted- average method of process costing. Data for the assembly department for October 2013 are as follows: Physical Units car costs Direct Conversion Materials CostsWork in process, Oct 1 *a 4,000 $1,248,000 $241,650Started during Oct 2017 22,500Complete during Oct 2017 26,000Work in process, Oct 31 *b 500Total costs added during Oct 2017 $4,635,000 $2,575,125a - Degree of completion: direct materials,?%; conversion costs, 45%.b - Degree of completion: direct materials,?%; conversion costs, 65%.1.
