Answer:
1.7$
Step-by-step explanation:
Given
original price = $2.87
New price = $2.82
Percentage decrease = original price-New price/New price × 100
Percentage decrease = 2.87-2.82/2.87× 100
Percentage decrease = 0.05/2.87 × 100
Percentage decrease = 5/2.87
Percentage decrease = 1.7%
Jamal has 30 ounces of a 20% saline solution. This means 20% of the solution is salt. He combines this solution with 25 ounces of a 30% saline solution.
What is the total amount, in ounces, of salt in the combined mixture? Please help and please provide an explanation?
Answer:
12.5 or 12 1/2 (may be wrong)
Step-by-step explanation:
First I set up a formula to solve how many ounces of salt there were out of 30,
x/30=20/100, I crossed multiplied and got 5/30, next, I set up the same formula for how many ounces of salt there were out of 25, x/25=30/100, I got 7.5, the last thing I did was add them both together leading me to the answer 12.5 or 12 1/2. Hope this helps! Please say if I am wrong.

Suppose one of your friends was absent from school on the day your math class learned about graphing rational numbers on the number line. Using complete sentences, explain to your friend how to graph the opposite of 6.2 on the number line.
Answer:
So i would ask this friend to draw a number line and label 6.2 on the number line. Then i would ask her if she knew what the opposite number of 6.2 is.
Yes- The number line will always continue, its indefinite. This means it can go forward or backwards. Make sure that your friend wrote 0. You always need a starting point. Then tell her to draw the tally marks forward the same way she did backwards. Locate the 6.2 and make all of the numbers negative.
The complete sentences to explain to your friend how to graph the opposite of 6.2 on the number line as shown below.

suppose v varies directly as g, and v= 36 when g = 4. find v when g=11
Answer:
v = 99 when g = 11
Step-by-step explanation:
Set this up as an equation
36/4 = v/11
Cross multiply
36 × 11 = 4 × v
396 = 4v
Divide both sides by 4 to isolate variable v
396 ÷ 4 = 4v ÷ 4
99 = 1v
99 = v

Answer: length = 8cm
Width = 4cm
Step-by-step explanation:
Let the width of the rectangle be represented by x.
Since the length of a rectangle is twice as long as the width of the rectangle, then the length will be: = 2 × x = 2x
Note that, Area of a rectangle = Length × Width
Therefore,
2x × x = 32
2x² = 32
Divide both side by 2
2x²/2 = 32/2
x² = 16
x = ✓16
x = 4
Therefore, width = 4cm
Since length = 2x
Length = 2 × 4cm = 8cm
Check: length × width = Area
8cm × 4cm = 32cm²

What is the inverse equation for f(x)=x+6
Answer:
y^-1 = x - 6
Step-by-step explanation:
change f(x) to 'y'
switch 'x' and 'y'
solve for 'y'
Answer:
Step-by-step explanation:
y = x + 6
x = y + 6
y + 6 = x
y = x - 6
f^-1(x) = x - 6

If there are 150 people born in the world every minute; how
many are born every Hour? Day? Year?
Step-by-step explanation:
150 x 60 = 9,000 every hour
9000 x 24 = 216,000 every day
216000x 365 = 78,840,000 every year
Answer:
Hour: 9,000 people
Day: 216,000 people
Year: 78,840,000 people
Step-by-step explanation:
In order to solve this, you need to identify how many minutes there are in an hour, a day, and a year:
Hour: 60 minutes
Day: 60 minutes × 24 hours = 1,440 minutes
Year: 60 minutes × 24 hours × 365 days = 525,600 minutes
Now, you need to multiply each of these numbers by 150 to find how many people are born every hour, day, and year:
Hour: 60 minutes × 150 people = 9,000 people
Day: 1,440 minutes × 150 people = 216,000 people
Year: 525,600 minutes × 150 people = 78,840,000 people

[tex]AB^{2} +6^{2} =10^{2} =100\\\\AB^{2} =100-36=64\\\\AB=\sqrt{64}=8\\[/tex]
all three pairs of appropriate sides of a triangle are proportional, the ratio is the same.
10/5=8/4=6/3=2 so the triangles are similar
