Answers

Answer:

$288

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 18%/100 = 0.18 per year,

then, solving our equation

I = 3200 × 0.18 × 0.5 = 288

I = $ 288.00

The simple interest accumulated

on a principal of $ 3,200.00

at a rate of 18% per year

for 0.5 years is $ 288.00.

Mr. Jones has a new car. The manufacturer says that the car should get about 28 miles per gallon in the city. About how many miles can Mr. Jones drive on 11.5 gallons of gas? At 2.89 per gallon, how much would that cost?

Answers

Answer:a) 322 MILES  B) 34.391 ( The price per gallon was not given in units ) but if price of I gallon = lets say $2.89, then for 11.5 Gallons will be $34.391

Step-by-step explanation:

a)

M r Jones car needs 28 miles for 1 gallon = 28 MILES= 1 Gallon

Number of miles he can drive withe 11.5 gallons

1 Gallon = 28 miles

11.5 gallons = 11.5 x 28miles = 322 miles

b)  IF 1 gallon costs 2.89

11.5 gallons will  cost= 11.5 x 2.89= 34.391

Answer:

The value of n is 6.

Step-by-step explanation:

Given that these 2 triangles form a square so we can assume that all sides are same. Then, we have to apply Pythagoras Theorem, a² + b² = c², where a, b are sides and c is hypotenuse :

n² + n² = (6√2)²

2n² = 6² × (√2)²

2n² = 72

n² = 72 ÷ 2

n² = 36

n = √36

n = 6

Dixie drinks 1/3 a cup of water in 1/6 of a minute. How many cups of water per minute does Dixie drink?

Answers

2 drinks! Can I pls have brainliest??

Hello, 928747! I can help.

So, we're trying to find out how many cups of water Dixie can drink per minute.

Since there are 60 seconds in a minute, we can assume that 1/6 of a minute is 10 seconds

1/6 = 10/60

So there are 60 seconds in a minute so we would multiply 1/3 by 6 to find how many cups she can drink in one minute

1/3 x 6 = 2

So, Dixie can drink 2 cups in one minute.

Find the 13th term of the geometric sequence 3, -15, 75, ...​

Answers

the terms of geometric sequence are 3, -15, 75

given,

1st term (a) = 3

second term (t2)=-15

common ratio (r) = t2/t1

=-15/3

=-5

then

t13= ar^n-1

=3×(-5)^13-1

=3×244140625

=3×244140625

=732421875.

The [tex]13^{th}[/tex] term of the geometric sequence is - 732421875.

A geometric sequence is given ; 3 , -15 , 75....

We have to find the [tex]13^{th}[/tex]  term of the geometric sequence.

What is the formula for calculation of nth term of geometric Sequence ?

The formula for calculation of nth term of geometric progression is [tex]a_{n}[/tex] = [tex]a_{1}[/tex] × [tex](r)^{n-1}[/tex] where r is the common ratio of geometric sequence.

Given geometric sequence is 3 , -15 , 75....

and

Common ratio is r.

i.e., r = -15 ÷ 3 = -5

∵ [tex]n^{th}[/tex] term of a geometric sequence is given by  ;

[tex]a_{n}[/tex] = [tex]a_{1}[/tex] × [tex](r)^{n-1}[/tex]  

where [tex]a_{1}[/tex] is the first term.

So,

[tex]13^{th}[/tex] term of the geometric sequence will be ;

[tex]a_{13}[/tex] =  3 × [tex](-5)^{12}[/tex]

[tex]a_{13}[/tex]   =  - 732421875

Thus ,  the [tex]13^{th}[/tex] term of the geometric sequence is - 732421875.

I'm having trouble with the second to last step in the fifth question.
1
1 1
x 1 1 (This is a right triangle)
1 69° 1
1-------------1
11
1. first identify a trigonometric ratio that will make it possible to find the value of x.
Answer = X is opposite to the angle 69° and 11 is adjacent to the angle 69°

2. To find the unknown​ value, which trigonometric function should be​ used?
Answer = Tangent

3. Use the tangent ratio for TAN 69°.
Answer = TAN 69° = [tex]\frac{x}{11}[/tex]

4. Multiply both sides by 11.
TAN 69° = [tex]\frac{x}{11}[/tex]
Answer = 11 · TAN 69° = x

5. Simplify
11 · TAN 69° = x
11(2.6051) ≈ x
(Blank) ≈ x
Answer = 28.7 ≈ x < -- (Rounded to the nearest tenth)

11(2.6051) ≈ x This is the part I'm having trouble with. I don't understand how to get the decimal in the parenthesis. I've tried dividing, multiplying, multiplying and then dividing. I just can't get the correct answer. I think I'm suppose to use a geometry calculator and input TAN then multiply(or divide I don't know), but I don't have one right now so I need to know if there's any way I could get the same answer with a regular calculator.
