4*5=20
8*(7-4)=24
20+24=44
The trick is to make the figure into two
There would be four zeros because 6×5=30, and 10 to the 3rd power would be 1000, and 30×1000=30000, which has four zeros.
Answer:
22 is the perimeter.
Step-by-step explanation:
You find the perimeter by adding up all of the sides of a shape. 9 + 9 = 18. 18 + 4 = 22.
Answer:
below explained briefly
Step-by-step explanation:
(a) to find the area of parallelogram use the formula:<em> b * h</em> = 30 * 20 = 600m^2
(b) <u>to find the area of shaded of this one: first we need to find the area of rectangle and then area of two triangle and subtract them with rectangle.</u>
area of rectangle : <em>length * width</em> = 25 * 7 = 175 cm^2
area of two triangles = 2<em>(1/2*b*h)</em> = 2 ( 1/2 * 7 * 5 ) = 35 cm^2
area of shaded = 175 - 35 = 140 cm^2
(c) there different methods of finding area of this figure.
<u>one of the famous methods are that we know it a equilateral triangle thus all sides are 60 degree</u>
<em>formula : 1/2 * a * b * sin(C)</em>
using this formula : 1/2 * 8 * 8 * sin( 60 )
: 27.7 cm^2
Answer:
The extra hours is 12 hours
Step-by-step explanation:
We are given
She has already saved up $50 for the dress
and this is equation of line
so, y-intercept is 50
![b=50](https://tex.z-dn.net/?f=b%3D50)
now, we can find slope
we can select any two points and then we can find slope
x1=0 , y1=50
x2=2 , y2=75
now, we can use formula
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
now, we can plug values
![m=\frac{75-50}{2-0}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B75-50%7D%7B2-0%7D)
![m=\frac{25}{2}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B25%7D%7B2%7D)
now, we can find equation
y=mx+b
![y=\frac{25}{2}x+50](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B25%7D%7B2%7Dx%2B50)
we are given y=200
so, we can set it to 200 and then we can solve for x
![200=\frac{25}{2}x+50](https://tex.z-dn.net/?f=200%3D%5Cfrac%7B25%7D%7B2%7Dx%2B50)
![\frac{25}{2}x=150](https://tex.z-dn.net/?f=%5Cfrac%7B25%7D%7B2%7Dx%3D150)
![25x=300](https://tex.z-dn.net/?f=25x%3D300)
![x=12](https://tex.z-dn.net/?f=x%3D12)
