Answer:

d=\sqrt(x2-x1)^{2}  + (y2-y1)^{2}

Step-by-step explanation:

1- Identify the x and  the y

x1= -2

x2=2

y1= 2

y2= -1

2-

2- solve the equation:

d=\sqrt\(2-(-2))^{2}  + ((-1)-2)^{2}

d= \sqrt(4)^{2}        + (-3)^{2}

= \sqrt16        + 9

= \sqrt25

d=5 answer

Find the value of x. Then find the measure of each labeled angle.<br> (9x - 10)<br> (5x + 38)
omeli [17]

Answer:

x=12 and

(9*12)-10=98

(5*12)+38=98

both angles are = 98

Step-by-step explanation:

do this :

9x - 10 = 5x + 38

( - 5x from both sides)

4x - 10 = 38

(add 10 to both sides)

4x = 38+10

4x=48

(divide by 4)

x=48/4

 = 12

substitute into the equations:

(9*12)-10

(5*12)+38

Movies are on sale for 3/
vredina [299]

Answer:

$7.50

Step-by-step explanation:

3/4 of the original price

Original price: $10

So we need 3/4 of $10

10 ÷ 4 = 2.5

2.5(3) = 7.5

3/4 of $10 = 7.5, so the price is now $7.50

The correct answer is: AB = 3.11

Explanation:
Since

cos(\theta) =  \frac{base}{hypotenuse} --- (1)
\theta = 50°
base = 2

And hypotenuse = AB

Plug in the values in (1):
(1) => cos(50°) = 2/AB

=> AB = 2/0.643
=> AB = 3.11

Your school is sponsoring a pancake dinner to raise money for a field trip. You estimate that 200 adults will attend. You are tr
AfilCa [17]

Answer:

Some of the possible combinations are;

1) $19 per adult, $0 per child

2) $10 peer adult, $9 per child

3) $14 peer adult, $5 per child

Step-by-step explanation:

The given information are;

The estimated number of adults to attend the fund raising dinner = 200 adults

The amount the fund raiser is trying to realize = 3800

Therefore, some of the possible combinations are;

1) 3800/200 = 19 per adult to give;

$19 per adult, $0 per child

2) Given that each adult is charged $10, we have;

Total amount from adults = $10 × 200 = $2000

The total amount to be raised from the children = The amount the fund raiser is to realize - (Total amount from adults)

∴ The total amount to be raised from the children = 3800 - 2000 = 1800

The total amount to be raised from the children = $1,800

If there are 200 children we have;

The amount charged per child = (The total amount to be raised from the children)/(The total number of children)

The amount charged per child = $1,800/200 = $9 per child

Therefore, we have;

$10 peer adult, $9 per child

3) If each of the 200 children are charged $5 each, we have;

The total amount to be raised from the children = $5 × 200 = $1,000

∴ The amount to be raised from adults = $3800 - $1000 = $2800

The amount to each adult is to be charged = $2800/200 = $14

Therefore, we have;

$14 peer adult, $5 per child.
