HELP ME WITH THIS GEOMETRY QUESTION!!! 18 POINTS!

ikadub [295]

Answer:

Step-by-step explanation:

The arcs are in the ratio:

3 : 3 : 4 : 5

Add all numbers in the ratio:

3 + 3 + 4 + 5 = 15

In the ratio, the sum of all numbers is 15.

In the real circle, the sum of the measures of all the arcs is 360.

360/15 = 24

Multiply all numbers in the ratio by 24.

72 : 72 : 96 : 120

Factor by grouping. 12x^3−20x^2+3x-5

Rudik [331]

First, group them in 2's (2 numbers per group)
and see which ones have the factors of each other

you want to group 12x^3 with 3x because 3 is a factor of 12
then you want to group -20x^2 and -5 together becuase 5 is a factor of 20 so
(12x^3+3x)+(-20x^2-5)
undistribute
(3x)(4x^2+1)+(-5)(4x^2+1)
revese distribute (ab+ac=a(b+c))
(3x-5)(4x^2+1)

Two airplanes are carrying food and medical supplies to a country in need. One airplane is carrying 63 meals and 57 medical kits

Tju [1.3M]

Answer:

63m + 57k = 714 ____________ (1)

78m + 57k = 789 ____________(2)

The price of one meal is $5

Step-by-step explanation:

Let the price of one meal be m.

Let the price of one medical kit be k.

One airplane is carrying 63 meals and 57 medical kits and the total cost for those supplies on that airplane is $714.

This means that:

63m + 57k = 714 ____________ (1)

The other airplane is carrying 78 meals and 57 medical kits and the total cost for the supplies on that airplane is $789.

This means that:

78m + 57k = 789 ____________(2)

We now a system containing two linear equations that can be used to solve to problem:

63m + 57k = 714 ____________ (1)

78m + 57k = 789 ____________(2)

To find the price of one meal, we subtract equation (1) from (2) and simplify:

78m + 57k = 789

- 63m + 57k = 714 _

15m = 75

=> m = 75 / 15 = $5

The price of one meal is $5
