Answer:

87th term is 497

Step-by-step explanation:

first, you have to find the nth term:

figure out the difference between your set of numbers (in our case +6)

that means that is 6n. next, the nth term is basically the 0th term so you have to find the 0th term. all you have to do is do the inverse of 6n (-6n or -6), which gives us -25.

nth term= 6n-25

now replace n with 87.

final step:

87*6 (6n and n=87) and that gives you 522. then, you have to do 522-25, due to the equation. 522-25=497

497 is your 87th term.

Answer:

Step-by-step explanation:

[tex]a = -19\\d = T_{2} -T_{1} \\d = -19-(-13)\\d = -19+13\\d = -6\\T_{n}= a+(n-1)d \\\\T_{87} = -19+(87-1)-6\\T_{87} = -19+(86)*-6\\T_{87} = -19-516\\T_{87} = -535[/tex]

Answer:

34/95

Step-by-step explanation:

Since 38 students choose football and 23 students chose tennis, then 95 - 38 - 23 = 34 students chose running. The probability is 34 / 95.

Answer:

y - x = - 5

Step-by-step explanation:

Applying the rule gives

x = [tex]\frac{1}{3}[/tex] × 36 + 9 = 12 + 9 = 21

y = [tex]\frac{1}{3}[/tex] × 21 + 9 = 7 + 9 = 16

Thus

y - x = 16 - 21 = - 5

Answer:

- 156250

Step-by-step explanation:

Find the ratio of the geometric sequence.

-10/2 =  -5

50/-10 = -5

The common ratio is -5.

Apply the formula.

an = ar^(n-1)

Where a is the first term and r is the ratio.

a8 = 2(-5)^(8-1)

a8 = 2(-5)^7

a8 = 2(-71825)

a8 = -156250

Answer:

Option C

Step-by-step explanation:

=> 4p + 2 = 8

Subtracting 2 to both sides

=> 4p = 8-2

=> 4p = 6

Dividing both sides by 4

=> p = 1.5

Answer:

The answer is C.

Step-by-step explanation:

First, you have to subtract 2 to both sides :

[tex]4p + 2 = 8[/tex]

[tex]4p + 2 - 2 = 8 - 2[/tex]

[tex]4p = 6[/tex]

Next, you have to divide it by 4 :

[tex]4p = 6[/tex]

[tex]p = 6 \div 4[/tex]

[tex]p = 3 \div 2[/tex]

[tex]p = 1.5[/tex]

Answer:

$36.41/week

Step-by-step explanation:

Divide 750 miles/wk by 28 MPG -> = 26.79 gallons/week (I rounded.)

Divide 750 miles/wk by 20 MPG -> = 37.50 gallons/week

Car -> 26.79 gallons x $3.40 = $91.09

SUV -> 37.50 gallons x $3.40 = $127.50

$127.50 - $91.09 = Difference of $36.41/week

The difference in the total weekly cost of gasoline is $36.43 if you drive an average of 750 miles per week.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

You drive an average of 750 miles per week in a car that gets 28 miles per gallon. With gasoline prices at $3.40 per gallon.

For the first car:

Total number of miles = 750 miles

The gasoline prices at $3.40 per gallon

The car that gets 28 miles per gallon

Number of gallons used = 750/28 = 26.785

The total price of the gallon used = 26.785x3.40 = $91.07

For the SUV car:

Total number of miles = 750 miles

The gasoline prices at $3.40 per gallon

The car that gets 20 miles per gallon

Number of gallons used = 750/20 = 37.5

The total price of the gallon used = 37.5x3.40 =  $127.5

The difference in total weekly cost of gasoline = 127.5 - 91.07 = $36.43

Thus, the difference in the total weekly cost of gasoline is $36.43 if you drive an average of 750 miles per week.

Answer:

The single transformation that maps a onto c is the reflection of the triangle a  about the line y = -x

Step-by-step explanation:

To answer the question, we note that the result of reflection of a point (x, y) across the x axis is given as follows;

Coordinates before reflection = (x, y), Coordinates after reflection = (x, -y)

Also, when we rotate a  point, (x, y), 90° clockwise, we have;

Image point before 90° clockwise rotation = (x, y), Image point after 90° clockwise rotation = (y, -x)

Therefore, the rotation of the point (x, -y), 90° clockwise will give

Image point before 90° clockwise rotation = (x, -y), Image point after 90° clockwise rotation = (-y, -x)

Which gives the combined transformation as (x, y) → (-y, -x) which is the rule equivalent to reflection about the line y = -x.

Answer:

5668.3

Step-by-step explanation:

The problem can be represented as a right angled triangle as shown below.

The angle of depression is equivalent to the angle inside the triangle (alternate angles) and it is 34°.

The altitude of the balloon is 2999 feet. (opposite)

Using trigonometric function, SOHCAHTOA, we can solve this:

[tex]sin(34) = \frac{opposite}{hypotenuse}\\ \\sin(34) = \frac{altitude}{distance}\\\\sin(34) = \frac{2999}{distance}\\\\distance = \frac{2999}{sin34}\\\\distance = 5668.3 feet[/tex]

The pilot is 5668.3 feet far away from the house.

Answer: 1324.12 sq. cm.

Step-by-step explanation:

A=2πrh+2πr2

A = 2π x 8.2 x 17.5 + 2π x 8.2^2

A = 2π x 143.50 + 2π x 67.24

A= 1324.12

Answer:

SA = 1324.1 cm²

Step-by-step explanation:

Surface Area of Cylinder = [tex]2\pi rh+2\pi r^2[/tex]

Where r = 8.2 cm, h = 17.5 cm

=> SA = [tex]2(3.14)(8.2)(17.5)+2(3.14)(8.2)^2[/tex]

=> SA = [tex]901.6+2(3.14)(67.24)[/tex]

=> SA = 901.6 + 422.5

=> SA = 1324.1 cm²

Step-by-step explanation:

Simple Interest = PTR/100

=1000* 30* 6/100

=1800.

Amount= Principal + Interest

= 1000+1800

= $2800

The amount of money that has at the of 30 years is $​2800.

Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time.

Unlike compound interest, which adds the interest from the principal of prior years to determine the interest of the following year, the principal amount in simple interest remains constant.

As per the given,

Principle amount P = $1000

Rate of interest R = 6%

Time span T = 30 years.

Total amount = Principle amount + Interest

Total amount = P + (PRT)/100

Total amount = $1000 + (1000 x 6 x 30)/100

⇒ $2800

Hence "The amount of money that has at the of 30 years is $​2800".

Answer:

The measure of angle a is 43 degrees.

Step-by-step explanation:

Angle P is congruent to Angle R. A triangle's angles add up to 180 degrees. 47*2=94. 180-94=86 degrees. 86/2=43 degrees.

Answer: 43°

Step-by-step explanation:

The degree of a triangle adds up to 180. We are given an angle of 47 and there is a right angle of 90

We now have 90 + 47 + a = 180

137 + a = 180
