Is 10% of 10% of 100 the same as 20% of 100?

Lelu [443]

No;

20% of 100 = 0.20 x 100 = 20
10% of 10% of 100 = 0.10 x 0.10 x 100 = 1

What is the recursive rule for the sequence?

babymother [125]

Answer:

$a_{n} =a_{n-1} -5.6$ where $a_{1} =-2.7$

Step-by-step explanation:

This is an arithmetic sequence with the first term is $a_{1}$ = -2.7 and has a common difference of $d=-5.6$ .

Arithmetic Sequence: $a_{n} =a_{n-1} +d$

$a_{n}$ is the nth term and $d$ is the common difference.

The common difference: -2.7, -8.3, -13.9...

Subtract: -2.7- (-8.3) = -5.6, -13.9 - (-8.3) = -5.6

Common difference: $d = -5.6$

Recursive rule: $a_{n} = a_{n-1} -5.6$

What is the length of AB

Anettt [7]

Answer:

$\boxed{\boxed{\overline{AB}=16}}$

Step-by-step explanation:

In the triangle ABC, m∠ABC=90°. Hence, it is right angle triangle.

$\tan \theta=\dfrac{p}{b}=\dfrac{AB}{64}$ --------1

In the triangle ABD, m∠ABD=90°. Hence, it is right angle triangle.

$\cot (90-\theta)=\dfrac{b}{p}=\dfrac{4}{AB}$

As $\cot (90-\theta)=\tan \theta$ , so

$\tan \theta=\dfrac{b}{p}=\dfrac{4}{AB}$ ---------2

From equation 1 and 2,

$\Rightarrow \dfrac{AB}{64}=\dfrac{4}{AB}$

$\Rightarrow AB^2=64\times 4$

$\Rightarrow AB^2=256$

$\Rightarrow AB=\sqrt{256}$

$\Rightarrow AB=16$

Amy plans to spend 1/4 of his next month's income on

kifflom [539]

9514 1404 393

Answer:

$505

Step-by-step explanation:

Assuming the listed expenses comprise all of Amy's income (x), we have ...

(1/4)x +(1/12)x +(1/6)x + 590 +925 = x

1515 = 1/2x . . . . . . subtract 1/2x

We note that 1/6x is for food. That amount is 1/3 of 1/2x, so the amount spent on food is ...

(1/6)x = (1/3)(1/2x) = (1/3)(1515) = 505

Amy plans to spend $505 on food.
