The area of the triangle is 126 square units. Then the correct option is D.
What is the area of the triangle?Assume 'h' is the height of the triangle and 'b' be the base of the triangle. Then the area of the triangle is given as,
A = (1/2) × h·b
The height of the triangle will be 12 units and the base of the triangle will be 21 units. Then the area of the triangle is calculated as,
A = 1/2 x 21 x 12
A = 21 x 6
A = 126 square units
Thus, the correct option is D.

Answers
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.

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).
Answers
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 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.
Answers
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.

340 miles
430 miles
330 miles
240 miles
Answers
Answer:240 miles
Step-by-step explanation: the reason they have 240 miles left to drive is because on the first day they drove 365 miles so you would subtract that by the total and you get 971 miles then you subtract 421 miles witch is what they drove on the second day by 971 and you get 550 and then you subtract 550 by 310 miles witch is what they drove on day 3 and then you get 240 miles.

how many more calories do you burn per minute downhill skiing than hiking
Answers
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

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.
