Answer:

The number of men was 80

The number of women was 70

Step-by-step explanation:

The question in English is

Having organized a bingo has raised $1900. For the entrance of men $15 and women $10 and an attendance of 150 people has been reported. Determine the number of men and the number of women who participated in the bingo.

Let

x----> the number of men

y----> the number of women

we know that

x+y=150

x=150-y -----> equation A

15x+10y=1,900 -----> equation B

substitute equation A in equation B and solve for y

15(150-y)+10y=1,900

2,250-15y+10y=1,900

15y-10y=2,250-1,900

5y=350

y=70

Find the value of x

x=150-70=80

therefore

The number of men was 80

The number of women was 70

Ethan had $8 more than Dakota. Ethan then gave 1/4 of his money to Dakota. The ratio of money Ethan had to the money Dakota had
Paha777 [63]

Answer:

The amount with Dakota = $0.421

The amount with Ethan = $8.421

Step-by-step explanation:

Let the Initial amount with Dakota be 'x'

Therefore,

Amount with Ethan = x + $8

After giving \frac{1}{4} of money to the Dakota i.e \frac{1}{4} of ( x + $8)

Amount available with Dakota = x + [\frac{1}{4}\times(x+8)]

= \frac{5}{4}x+2

Amount available with Ethan = (x + $8) - [\frac{1}{4}\times(x+8)]

= \frac{3}{4}x+6

Now,

\frac{\frac{3}{4}x+6}{\frac{5}{4}x+2}=\frac{5}{2}

or

\frac{\frac{3x+24}{4}}{\frac{5x+8}{4}}=\frac{5}{2}

or

2(3x + 24) = 5(5x + 8)

or

6x + 48 = 25x + 40

or

25x - 6x = 48 - 40

or

19x = 8

or

x = $0.421

Hence,

The amount with Dakota = $0.421

The amount with Ethan = x + $8

= $0.421 + $8

= $8.421

Very easy!!! Find length
bixtya [17]

Answer:

Option D

Step-by-step explanation:

From the picture attached,

If each block of the graph is a square with the dimension of 1 unit,

Measure of leg 1 = 5 units

Measure of leg 2 = 12 units

By applying Pythagoras theorem in the right triangle given in the picture,

(Hypotenuse)²= (leg 1)² + (leg 2)²

(Hypotenuse)²= (5)² + (12)²

(Hypotenuse)²= 25 + 144

Hypotenuse = √169

Hypotenuse = 13

Therefore, length of the given line will be 13.

Option D is the answer.

What is the slope of line segment AB? Keep as a reduced fraction.<br> B<br> A
ladessa [460]

Answer:

2

Step-by-step explanation:

Use rise over run (y2 - y1) / (x2 - x1) where (x1, x2) and (y1, y2) are points on the line

Plug in the points A (-3, -2) and B (1, 6)

(y2 - y1) / (x2 - x1)

(6 + 2) / (1 + 3)

8 / 4

= 2

So, the slope of line segment AB is 2.
