Answer:
24 inches.
Step-by-step explanation:
Given:
During a week the water level in a pond decreased by 4 in. Per day,
For two days, it decreased by half that amount = 
Question asked:
How much did the water level decrease in the pond in one week?
Solution:
As we know, there are 7 days in a week.
<u>For 5 days,</u>
Each day water level decreased by = 4 inches
In 5 days, water level decreased by = 
<u>For exceptional 2 days:</u>
Each day water level decreased by = 2 inches
In 2 days, water level decreased by = 
Water level decreased in whole week = 20 + 4 = 24 inches
Therefore, water level decreased 24 inches in the pond in one week.
Answer:
what is the circle.
Circumference is diameter x 3.14.
Diameter is the whith of a circle.
Ex. diameter = 4
4 x 3.14 = 12.6cm.
Step-by-step explanation:
28 is 43.75% of 64
you can calculate this by making a fraction of 28/64 and timing this by 100!
Given inequality -3(4-6x) < x+5.
We have -3 in front of Parenthesis.
That represents multiplication of -3 and Parenthesis.
The multiplication of Parenthesis could be done by applying distributive property.
On distributing, we get
-12+18x < x+5
x is added on right side of the inequality. The reverse operation of addition is subtraction. So we need to subtract x from both sides, we get
-12+18x-x < x-x+5
-12+17x < 5
Now, we need to get rid -12 from left side.
So, we need to apply addition property of equality, we need to add 12 on both sides, we get
-12+12+18x < x+5+12
17x < 17
We need to get rid 17 from left side. So we need to apply division property of equality.
On dividing both sides by 17, we get
17x/17 < 17/17
x<1.
So here's how to do it,
slope intercept form is y=mx+b
m is the slope, b is the y- intercept, X is your unknown variable.
you need to solve to get y by its self to get your slope.
for perpendicular lines flip the slope
ex 1, smy=2x+6 --- slope of a perpendicular line will be 1/2
ex 2, y=3/2+8 ---8 perpendicular lien would have a slope of 2/3
parallel lines have the same slope so any equation with with the same slope will be parallel if it has the same degree.
ex. y=2x+14 is parallel to y= 2x+56
slope can be found using the following formula if you have two sets of points on the same line
m= y2-y1 ÷ X2 - X1
