Answer:

17/40

Step-by-step explanation:

First let's find the least common denominator. The denominators are 8 and 25 so we need to find the least common multiple of 8 and 25.

8=2*2*2

25=5*5

Since they share no common factors the least common multiple of 8 and 25 is 8*25 which is 200.

Now we convert the fractions:

5/8*25/25=125/200

5/25*8/8=40/200

Then we subtract:

125/200-40/200=85/200

Now we simplify it:

17/40

Answer:
17/40
Step-by-step explanation:

First, we need to find the common denominator of 5/8 and 5/25, which is 200.

5 x 25/ 8 x 25 - 5 x 8 / 25 x 8
= 125/200 - 40/200

Next, subtract both fractions:

85/200 is our difference.

Let's simplify, divide both sides of the fraction by 5:

85 / 5 and 200 / 5
= 17/40

17/40 is your simplified answer.

Serggg [28]

The price of 1 senior citizen ticket is $ 8

Solution:

Let "x" be the price of 1 senior citizen ticket

Let "y" be the price of 1 child ticket

The school sold three senior citizen tickets and one child ticket for a total of $38

Therefore, we frame a equation as:

three senior citizen tickets x price of 1 senior citizen ticket + one child ticket x price of 1 child ticket = 38

$3 \times x + 1 \times y = 38$

3x + y = 38 --------- eqn 1

The school took an $52 on the second day by selling three senior citizen tickets and two child tickets

Therefore, we frame a equation as:

three senior citizen tickets x price of 1 senior citizen ticket + two child ticket x price of 1 child ticket = 52

$3 \times x + 2 \times y = 52$

3x + 2y = 52 ---------- eqn 2

Solve eqn 1 and eqn 2

Subtract eqn 1 from eqn 2

3x + 2y - 3x - y = 52 - 38

Substitute y = 14 in eqn 1

3x + y = 38

3x + 14 = 38

3x = 24

Thus the price of 1 senior citizen ticket is $ 8

State the correct polar coordinate for the graph shown:

ANTONII [103]

Answer:

Solution : ( - 8, - 5π/3 )

Step-by-step explanation:

There are four cases to consider here, the first two with respect to r > 0, the second two with respect to r < 0. For r < 0 we have the coordinates ( - 8, 60° ) and ( - 8, - 300° ) . - 300° in radians is - 5π/3, and hence our solution is option d. But let me expand on how to receive the coordinates. Again r is the directed distance from the pole, and theta is the directed angle from the positive x - axis.

So when r is either negative or positive, we can tell that this point is 8 units from the pole. Therefore - r = - 8 in both our second cases ( we are skipping the first two cases for simplicity ). For r < 0 the point will lay on the ray pointing in the opposite direction of the terminal side of theta.

Our first coordinate is ( - 8, 60° ). Theta will be 2 / 3rd of 90 degrees, or 60 degrees, for - r. Respectively the remaining degrees will be negative, 360 - 60 = 300, - 300. Our second point for - r will thus be ( - 8, - 300° ) . - 300° = - 5π/3 radians, and our coordinate will be ( - 8, - 5π/3 ).
