Lenght=22 hand*(20 cm/1 hand)=440 cm
width=18 hand*(20 cm/1hand)=360 cm

Area=lenght x width.
Area=440 cm * 360 cm=158,400 cm²≈160,000 cm²

A) 160,000 cm²

Answer:

(a) i believe it is $10

(b)I believe it is 98 people

Step-by-step explanation:

(a) we are trying to find "?" for this explanation. I came up with the equation 60=6 x ?. The 60 shows us the total amount of dollars that the 6 shares went down. We need to find the amount. of dollars that went down for 1 stock. So we divide 60 by 6. and get 10.

(b) we are trying to find "?" for this explanation. I came up with the equation

?=7 x 14. All you have to so is multiply 7 by 14 and you get 98.

Hope this helps :)

The drawing is composed of a rectangle and a semicircle. Find the area of the figure to the nearest unit. Please explain, thank
DanielleElmas [232]
We know that
[area of the figure]=[area of rectangle]+[area of semi circle]

area of rectangle=b*h------> 10*18-----> 180 cm²

area of semicircle=pi*r²/2
diameter=18 cm
radius=18/2----> 9 cm
area of semicircle=pi*9²/2-----> 127.17 cm²

[area of the figure]=[180]+[127.17]------> 307.17 cm²
round <span>to the nearest unit </span>------> 307 cm²

the answer is
the area of the figure is 307 cm²

What are the solutions?<br>8x^2-12x-23=-5​
erastova [34]

Answer:

x = 3/4 + (3 sqrt(5))/4 or x = 3/4 - (3 sqrt(5))/4

Step-by-step explanation:

Solve for x over the real numbers:

8 x^2 - 12 x - 23 = -5

Divide both sides by 8:

x^2 - (3 x)/2 - 23/8 = -5/8

Add 23/8 to both sides:

x^2 - (3 x)/2 = 9/4

Add 9/16 to both sides:

x^2 - (3 x)/2 + 9/16 = 45/16

Write the left hand side as a square:

(x - 3/4)^2 = 45/16

Take the square root of both sides:

x - 3/4 = (3 sqrt(5))/4 or x - 3/4 = -(3 sqrt(5))/4

Add 3/4 to both sides:

x = 3/4 + (3 sqrt(5))/4 or x - 3/4 = -(3 sqrt(5))/4

Add 3/4 to both sides:

Answer:  x = 3/4 + (3 sqrt(5))/4 or x = 3/4 - (3 sqrt(5))/4
