Answer:

63°.

Step-by-step explanation:

To find the angle we can use as limits of the figure the intersection of y = 2x-4 with the x-axis and any point at the right of it.

To find the intersection of y = 2x-4 with the x-axis we do y=0:

0 = 2x-4

4 = 2x

x = 4/2 = 2.

Then, the left limit is (2,0). Now, let's use x=3 as an example to find the right limit:

y = 2(3)-4

y = 6-4

y = 2.

Then, the right limit is (3,2). You can see it in graph below. As you can see, the acute angle \alpha we are searching for can be calculated with the horizontal and vertical distances of the triangle limited by the two points, the line and the x-axis. So,

tan(\alpha) = \frac{2}{1}

tan(\alpha) = 2

\alpha = tan^{-1}(2)

\alpha = 63.43\textdegree \approx 63\textdegree.

Nolan has some nickels and some dimes. He has no more than 19 coins worth no less than $1.30 combined. If Nolan has 5 nickels, d
Allushta [10]

Answer:

number of dimes 11 to 14

Step-by-step explanation:

given data

coin = 19

worth no less = $1.30

Nolan nickles = 5

solution

we convert 5 cent to dollars, it will be

5÷100 = $0.05

and

dime is worth 10 cents

so it will be 10 ÷ 100 = $0.1

so we consider here x as the number when nickels.

and we consider y as the number of dimes.

so here we can say

x + y ≤ 19      ..........................1

as here no less than $1.30 combined.

so

0.05 x + 0.1 y ≥ 1.3       ......................2

and

when Nolan has 5 nickels

put x = 5 in eq 1

5 + y ≤ 19  

y ≤ 19 - 5

y ≤ 14

and

now we put x = 5 in eq 2

0.05 × 5 + 0.1y ≥ 1.3

0.25 + 0.1y ≥ 1.3

0.1y ≥ 1.3 - 0.25

0.1y ≥ 1.05

y ≥ 10.5

so all possible values for the number of dimes 11 to 14
