Answer:
3.456E + 14= 
Step-by-step explanation:
The river discharges 
cubic feet of water into the Pacific Ocean each second.
There are 86,400 seconds in one day.
Amount of water discharges each day
Since this differs from what you have, I will explain the scientific notation.
3.456E + 14 simply means
The options are not well laid out but you can pick the appropriate option.
1.Simplified each one
2/5 (both divided by 7) , 1/2 (divided by 21)
2.Make them into integer
(2/5 )*(2/2)=4/10 , (1/2)*(5/5)=5/10
Now the dominators are the same ,you can just compare the numerators. It is 4:5
Question 3
C(1, -7) D(-8, -7)
To find side length DC you count how many units are between the two points. C(1) D(-8) = 9 units
Question 1
Again count the points around the edge of the square. Since this shape is a rectangle, side length WX = YZ and side length XY = WZ.
WX = YZ = 11 units
XY = WZ = 15 units
Perimeter = WX + YZ + XY + WZ = 11(2) + 15(2) = 52 units
Answer:
All of their tickets cost $425.00
Step-by-step explanation:
a= adults c=children
$1700 divided by a=4
$1700 divided by c=2
A) 65%
b) 68
26:40 as x:100
26/40 = x/100
Cross multiply
2600 = 40x
x = 65
———————
85% of 80
0.85 is the decimal equivalent of 85%
80 x 0.85 = 68
