Answer 1
It is C because
31-71=102
And then 180=triangle
180-102=78
Answer 2

Answer:

The correct answer is C

Step-by-step explanation:

Helpful fact- All triangles are 180 degrees

Angle 1 = 31 degrees

Angle 2= 71 degrees

X= Angle 3

Y = Angle 1&2 Sum

So by adding Angles 1 & 2 we get a sum  to subtract from 180 and get a difference. That difference will be Angle 3.

Angle 1 + Angle 2 = Y

180 - Y= X

31 + 71 = 102 degrees   Y= 102 degrees

180 - 102 = 78 degrees  X= 78 degrees

Answer:C

Step-by-step explanation:In a box plot the median is the line that lines with the number that on the box plot. So the line is between 8 and 9 but to find the number that is between 8 and 9,first add 9+8=17 then divide 17 with 2 which is 17÷2=8.5.Therfore the numbers that are between 8 and 9 is 8.5.

The answer would be 8.5 so C

A8=21 a10=27 find nth term arthemetic sequence

Answers

Answer:

an = 3n - 3

Step-by-step explanation:

The nth term of an arithmetic progression is expressed as;

an = a + (n-1)d

a is the first term

n is the number of terms

d is the common difference

a8 = a + (8-1)d

a8 = a + 7d = 21 ....1

a10 = a+9d = 27 ....2

Subtract 1 from 2

7d  - 9d = 21 - 27

-2d = -6

d = -6/-2

d = 3

Since a + 7d = 21

a + 7(3) = 31

a + 21 = 21

a = 21 - 21

a = 0

Get the nth term

Recall that an = a + (n-1)d

an = 0 + (n-1)*3

an = 3n - 3

Hence the nth term of the sequence is 3n - 3

Answer:

[tex]2x+3y\geq 60\\x>10[/tex]

Step-by-step explanation:

We know that she will be selling bracelets for $2 each and earrings for $3 each. That means we will have 2x+3y, where x is the number of bracelets she sells and y is the number of earrings she sells. Then we will have [tex]\geq 60[/tex] because she wants to sell at least $60 worth of earrings and bracelets. That means the amount she makes from bracelets and earrings combined has to equal 60 or more, thus we use the greater than or equal to sign.

Now we have [tex]x>10[/tex], where x is still the number of bracelets sold. She said she will sell more than 10, which means we will just have [tex]>10[/tex]. If she said she wanted to sell at least 10, then it would be [tex]\geq10[/tex].

Therefore the system of inequalities is:

[tex]2x+3y\geq60\\x>10[/tex]

The value of a car with an initial purchase price of $15,250 depreciates by 16% per year. How much is the car worth after 6 years? Find f(6):

a=15,250

r=0.016

x=6

Please correct me if my rate is wrong please provide the work.

Answers

Answer:

$13842.43

Step-by-step explanation:

Given data

Value of car=$15,250

Rate of depreciation= 16%

Time = 6 years

We can use the exponential function below to model the value of the car after 6 years

v(t)= a(r)^x

But r= 1-0.016----------Because the value is depreciating

a=15,250  

r=0.016  

x=6

Substitute

v(t)= 15250(1-0.016)^6

v(t)=  15250(0.984)^6

v(t)=  15250*0.9077

v(t)= $13842.43

Hence the value will be $13842.43 after 6 years

Christine bought 9m ribbon lace for her school project. One yard of the lace cost P5.00
How much did Christine pay in all?​

Answers

Step-by-step explanation:

Given 1 yard = 0.9144m

0.9144 m = 1 yard

1 m = 1/0.9144 yards = 1.094yards

9m = 9 x 1.094 yards = 9.846yards

given 1 yard = P5.00

9.846 yards = P5.00 x 9.846 = P49.23

Step-by-step explanation:

Nevada has the fastest-growing population according to the U.S. Census bureau. In 2004, the population of Nevada was 2.62 million and increasing at an annual rate of 3.5%. What is the expected population in 2010? Apply the population growth formula N=Noe^rt

Applying the formula given above

N=Noe^rt

No = 2.62 million

r = 3.5% = 0.035

t = 2010 - 2004 = 6 years

N = 2.62 × e^6 × 0.035

N = 3.2322365171 million

= 32,322,237 millon

Approximately = 3.23 millon
