Answer:

22

Step-by-step explanation:

The number of male friends : 200 ÷100 × 45 = 90

The number of female friends : 200 - 90 = 110

Joan likes 20% of her female friends and there are total of 110 female friends

20% 110 would be➡ 110 ÷ 100 × 20 = 22

What is the area?? Please help
Olegator [25]

Answer:

<h3>324 ft²</h3>

Step-by-step explanation:

We have the triangle and the rectangle.

The formula of an area of a triangle:

A_{\triangle}=\dfrac{1}{2}bh

b - base

h - height

The formula of an area of a rectangle:

A_{\boxed{\ }}=lw

l - length

w - width

We have b = 24 ft, h = 7 ft, l = 24 ft and w = 10 ft.

Substitute:

A_\triangle=\dfrac{1}{2}(24)(7)=(12)(7)=84\ ft^2

A_{\boxed{\ }}=(24)(10)=240\ ft^2

The area of the figure:

A=A_{\triangle}+A_{\boxed{\ }}

Substitute:

A=84+240=324\ ft^2

Please solve this for me.<br> Thanks

Answer:

10y = 13x + 139

Step-by-step explanation:

Points (-5, -3) and (-15, -16) are the two points through which Line 1 passes.

So, the slope of the line 1 is \frac{-3-(-16)}{-5-(-15)} =\frac{13}{10}

Now, the slope of the parallel straight line i.e. line 2 will be same as line 1 i.e. \frac{13}{10}

Let us assume that the equation of line 2 is

y= \frac{13}{10} x+c {Where c is a constant} ....... (1)

Now, line 2 passes through the point (-13, 17). Hence, this point will satisfy equation (1).

So,  17= \frac{13}{10} (-13)+c

⇒ c=\frac{139}{10}

Therefore, the equation of line 2 will be

y=\frac{13}{10} x+\frac{139}{10}

⇒ 10y = 13x + 139  (Answer)

7/8 as a sum of fractions
Ratling [72]

(I am not sure if this is what you are looking for)

7/8 is seven eights, so we can break it into 7 parts.

\frac{1}{8} + \frac{1}{8} + \frac{1}{8} + \frac{1}{8} + \frac{1}{8} + \frac{1}{8} + \frac{1}{8} = \frac{7}{8}

Hope this helps, have a nice day!
