Answer:

Extremely large and small numbers that have many zeros are long to write and take up a lot of room. So, by using scientific notation a number can be written shorter. For example, numbers such as 295,000,000,000 can be shortened to 2.95x10^{11}. This is easier to write and understand. This is why the scientific notation is used over standard.

the perimeter of a rectangle is 160ft. One fourth the length is the same as twice the width. Find the dimensions of the rectangl
Hitman42 [59]

Answer:

w = 80/9 ft.

L = 640/9 ft.

Step-by-step explanation:

L = length    w = width

2w = L/4  so 8w = L

160 = 2L + 2w

160 = 2(8w) + 2w

160 = 16w+2w

160 = 18w

80/9 = w

Help please my moms going to kill me if I don’t get this right
iragen [17]

Answer:

x=-\frac{41}{6}

Step-by-step explanation:

Pay attention to the two tick marks. This indicates that those sides are congruent to each other and so will the angles on the bottom and top. Therefore, we can set up the equation 137+2(-3x+1)=180 and solve for x:

137+2(-3x+1)=180

137+(-6x+2)=180

137-6x+2=180

139-6x=180

-6x=41

x=-\frac{41}{6}
