The difference between city hall and the post office is 6 1/2 miles ( six and one half)city hall is 1 1/3 (one and one fourth NO

Norma-Jean [14]

City hall to post office = 6 1/2 miles = represented by f
city hall to library site = 1 1/4 miles = represented by d
library site to post office = unknown. = represented by e

City hall to library site PLUS library site to post office IS EQUAL to city hall to post office

d + e = f

1 1/4 + e = 6 1/2

find e.
e = 6 1/2 - 1 1/4
e = 13/2 - 5/4
e = (13*2)/(2*2) - 5/4
e= 26/4 - 5/4
e = (26-5)/4
e = 21/4
e = 5 1/4 distance from library site to post office.

To check:
d + e = f

1 1/4 + e = 6 1/2
1 1/4 + 5 1/4 = 6 1/2
6 2/4 = 6 1/2
6 1/2 = 6 1/2

there is 4/5 lb of sand in science supplies. if one scoop of sand weighs 1/20 of a lb how many scoops of sand can maria get from

tatuchka [14]

We want to divide whole sand into scoops, so we have to divide 4/5 by 1/20. Lets do this

$\frac{ \frac{4}{5} }{ \frac{1}{20} }$
We know that if we want to divide 2 fraction we can multiply first by inverse of second fraction instead of dividing.,so:
$\frac{ \frac{4}{5} }{ \frac{1}{20} }$
$\frac{4}{5}* \frac{20}{1}= \frac{4*20}{5*1} = \frac{80}{5}= 16$ scoops - its our result.

Find local maximum minimum and saddle points f(x,y)=xy-2x-x^2

saveliy_v [14]

To find such critical points, you have to differentiate the function and let the derivative equal zero. Since this function is y written in terms of x, but implicitly, you must use implicit differentiation. Do you know how to do that?

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:

$A=84+240=324\ ft^2$

What is the area of this face?

SSSSS [86.1K]

Answer:

Hello! answer: 180

Step-by-step explanation:

what I did to find answer is cut them into pieces I cut the m into 3 pieces and now just have to multiply my base x height so for the left one I did 12 x 6 = 72 for the middle I did 6 x 6 = 36 and for the right one I did 12 x 6 = 72 I add these up so...

72 + 36 + 72 = 180 so the surface area is 180! I hope this helps!
