Answer:

n = 36

Step-by-step explanation:

4 : 5 = n : 45

It can be also written as :-

[tex]\frac{4}{5} = \frac{n}{45}[/tex]

Multiplying both the sides by 45 ,

[tex]=> \frac{4}{5} \times 45 = \frac{n}{45} \times 45[/tex]

[tex]=> n = 4 \times 9 = 36[/tex]

Step-by-step explanation:

the formula to find common ratio is

r= second term/first term

The common ratio of the given the geometric sequence is -0.3

A geometric progression, also known as a geometric sequence, is a sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.

Given that, a geometric sequence, is -162,54,-18.6,... we need to find the common ratio,

In a standard geometric sequence, a₁, a₂, a₃, a₄, a₅..... the common ratio is given by :-

a₂ / a₁ = a₃ / a₂ .... = r

Here, r = -54/162 = -18.6/54 = -0.3

Hence, the common ratio of the given the geometric sequence is -0.3

Step-by-step explanation:

the bold ones are the answers

Answer:

19657

Step-by-step explanation:

Exponentiation: 10 ^ 4 = 10000

Multiple: 2 * the result of step No. 1 = 2 * 10000 = 20000

Exponentiation: 7 ^ 3 = 343

Subtract: the result of step No. 2 - the result of step No. 3 = 20000 - 343 = 19657

percentage, a relative value indicating hundredth parts of any quantity.

Given,

A group of college students spent $58.50 for dinner

The students want to leave a tip of 15%.

We need to find how much they has to leave as tip.

Firstly we have to convert 15% to decimal.

We have to divide 15 by 100

15/100

0.15

Now we have to multiply 0.15 with 58.50 to find the 15% of 58.50

0.15×58.50

8.775

9

Hence, $9 is the tip the students has to leave.

Answer:

DFG = 28⁰

because DEFG is a rhombus

=> DF is a bisector of angle EFG

=> EFD = DFG

we also have: EG is perpendicular with DF

EG cuts DF at O

=> EOF is a right triangle at O

=> EFD = 90⁰ - 62⁰ = 28⁰

=> DFG = 28⁰
