Answer:
The country's population decreased about 5.8 % during this time period.
Step-by-step explanation:
Population in 1990 = 164 million
Population in 2010 = 155 million
Determine the percent decrease
The formula used is: [tex]Percent\:Decrease=\frac{Initial\:Value-New\:Value}{New\:Value}\times 100[/tex]
We have :
Initial Value = 164 million (164,000,000)
New Value = 155 million (155,000,000)
Finding percent decrease
[tex]Percent\:Decrease=\frac{Initial\:Value-New\:Value}{New\:Value}\times 100\\Percent\:Decrease=\frac{164,000,000-155,000,000}{155,000,000}\times 100\\Percent\:Decrease=\frac{9,000,000}{155,000,000}\times 100\\Percent\:Decrease=5.8\%[/tex]
So, The country's population decreased about 5.8 % during this time period.

Find the area of the kite with the given information.
Answer:
Area of the given kite = 84 square inches.
Step-by-step explanation:
Properties of the diagonals of a kite,
1). Diagonals are perpendicular to each other.
2). Longer diagonal bisects the smaller one.
Therefore, Length of smaller diagonal BD = 2×6 = 12"
In right ΔAEB,
m∠ABE = m∠EAB = 45°
Therefore, in isosceles triangle AEB,
AE = BE = 6"
Now the length of longer diagonal AC = AE + EC
AC = 6" + 8"
= 14"
Area of the given kite ABCD = [tex]\frac{1}{2}(d_1)(d_2)[/tex]
= [tex]\frac{1}{2}(AC)(BD)[/tex]
= [tex]\frac{1}{2}(14)(12)[/tex]
= 84 square inches

how many more calories do you burn per minute downhill skiing than hiking
Answer: 2 more calories skiing
Step-by-step explanation:
First find the slope of each line.
Slope of Skiing:
= (Y₂ - Y₁) / (X₂ - X₁)
= (400 - 240) / (50 - 30)
= 8
= 8 calories per minute
Slope of Hiking
= (360 - 120) / (60 - 20)
= 6
= 6 calories per minute
Difference:
= 8 - 6
= 2 more calories skiing

You kayak up a river at a rate of 192 feet every 2 minutes.You kayak down
a river at a rate of 423 feet every 3 minutes.How much farther do you
kayak in 5 minutes on the way down the river than in 5 minutes on the way
up the river.
Answer:
225 feet farther.
Step-by-step explanation:
This question can be solved using rules of three.
Up the river in 5 minutes:
You kayak up a river at a rate of 192 feet every 2 minutes. That is, a rate of 192/2 = 96 feet per minute.
So in 5 minutes, you will kayak 96*5 = 480 feet up the river.
Down the river in 5 minutes:
You kayak down a river at a rate of 423 feet every 3 minutes. That is, a rate of 423/3 = 141 feet per minute.
So, in 5 minutes, you will kayak 141*5 = 705 feet down the river.
How much farther do you kayak in 5 minutes on the way down the river than in 5 minutes on the way up the river.
706 - 480 = 225 feet farther.

X^9/7 convert from exponent form to radical form
Answer:
[tex]x^{\frac{9}{7}} = \sqrt[7]{x^9}[/tex]
Step-by-step explanation:
You can solve this by realising that the denominator of a fractional exponent can be expressed as the base of a radical.
Note also that the order does not matter. You could also express it as
[tex]\sqrt[7]{x}^9[/tex]
The reason this works is that you're effectively breaking the exponent into fractions. The first answer is the equivalent of:
[tex](x^9)^{1/7}[/tex]
and the second would be:
[tex](x^{1/7})^9[/tex]
In both cases, the exponents would be multiplied, giving the same result.

Step-by-step explanation:
CELL PHONES Many cell phone plans have an option to include more than one phone. The function for the monthly cost of cell phone service from a wireless company is f(x) = 25x + 200, where x is the number of phones on the plan. Find and interpret f(3) and f(5).
Answer:
f(3)=275, f(5)=325
Step-by-step explanation:
We just plug in 3 and 5 into the equation:
We get f(x) = 25x + 200
f(3) = 25*3 + 200
=75+200
=275
Interpretation: if there are three cell phones on the plan, then the total monthly cost is 275.
for f(5):
f(5) = 25*5 + 200
=125+200
=325
Interpretation: if there are five cell phones on the plan, then the total monthly cost is 325.
Answer:
f(3)= 75, which is the cost of a cell phone plan with 200 phones for 275 a month;
f(5)= 125, which is the cost of a cell phone plan with 200 phones for 325 a month;
A bag contains three red balls and six green balls you plan to select three balls at random determine the probability of selecting three green balls. The problem has to be done with combinations to determine the probability
Answer:
The answer is likley 6/9
Step-by-step explanation:
Total number of balls = 9
Red: 3/9 chance of being selected
Green: 6/9 chance of being selected
Basically, there is a way higher chance of selecting 3 green balls and an even HIGHER chance of selecting 6!
