Answer:

Given : x/3-5=6

answer = 23

Step-by-step explanation:

x-5=6*3

x-5=18

x=18+5

x=23

Answer:

33

Step-by-step explanation:

let the number be n , then the number divided by 3 is [tex]\frac{n}{3}[/tex] and decreased by 5

[tex]\frac{n}{3}[/tex] - 5 = 6 ( add 5 to both sides )

[tex]\frac{n}{3}[/tex] = 11 ( multiply both sides by 3 )

n = 33

The number is 33

Answer:

  [tex]P_1=11.7\\P_2=15.21\\P_n=9\cdot1.3^n\\P_{10}\approx124.07[/tex]

Step-by-step explanation:

An exponential function can be written in the form ...

  y = a·b^x

where x is the independent variable, b is the common ratio, and 'a' is the initial value (when x=0). The "common ratio" is the ratio of each term to the one before. For example, b = P₁/P₀.

Here, you are told the initial value (P₀) is a=9, and the common ratio is b=1.3. The independent variable is given as n, so your population formula is ...

  P(n) = 9·1.3^n

__

You are asked for values when n = 1, 2, and 10. Since you know the common ratio, you can simply multiply P₀ by 1.3 to get P₁:

  P₁ = 1.3·P₀ = 1.3·9 = 11.7

Similarly, ...

  P₂ = 1.3·P₁ = 1.3·11.7 = 15.21

__

You could continue up to P₁₀, but it is easier to use a calculator to evaluate the exponential function.

  P(10) = 9·1.3¹⁰ ≈ 124.07

Answer:

You can use the useful mnemonic: SOH CAH TOA to determine what function to use. Since  we have information about the hypotenuse (H) and opposite (O), we should use sine (S) for "SOH".

So yes, sine would be correct.

Answer:

4 : 3 > 7 : 9

Step-by-step explanation:

In order to compare two ratios or fractions, we make their denominators equal and then equate their numerators.

[tex]4 : 3 = \frac{4}{3} = \frac{4 \times 3}{3 \times 3} = \frac{12}{9} \\ \\ 7 : 9 = \frac{7}{9} \\ \\ \because \: 12 > 7 \\ \\ \therefore \: \frac{4}{3} > \frac{7}{9} \\ \\ \implies \: 4 : 3 > 7 : 9[/tex]

Answer:

Step-by-step explanation:

cot(x)=cos(x)/sin(x)

sin(x) + cos(x) * cos(x)/sin(x) = 1/f(x)

(sin^2 + cos^(x))/sin(x) = 1 / f(x)

1 / sin(x) = 1 / f(x)

Taking the reciprocal of both sides, we get

sin(x) = f(x)

Do the steps that I did on Problem A for each!!!!

A:-3(4-3p)

a=-3, b=4, c=3p

Apply the distributive law:

[tex]-3*4-(-3)*3p[/tex]

Add minus - plus rules:

[tex]-3*4+3*3p[/tex]

Simplify:

B:-3(7-6u)

a=-3, b=7, c=6u

=-3*7+3*6u

Simplify;

=[tex]-21+18u[/tex]

C:-6(-1+2c)

a=-6, b=-1, c=2c

=-6(-1)+(-6)*2c

=6*1-6*2c

Simplify:

=[tex]6-12c[/tex]

D:6(-n+7)

a=6,b=-n,c=7

Answer:

8%

Step-by-step explanation:

For simple interest, we use the equation I = PRT, where I is the interest earned, P is the principal/amount invested, R is the rate as a decimal, not percentage, and T is the time in years.

For this problem, we have to use 0.5 for T, because 6 months is 1/2 a year.

20 = (500)(r)(0.5)

20 = 250r

r = 0.08 = 8%

Answer:

{x I 8 < x < 65}

Step-by-step explanation:

{x I 8 < x < 65}

Given:

The rate of interest on three accounts are 7%, 8%, 9%.

She has twice as much money invested at 8% as she does in 7%.

She has three times as much at 9% as she has at 7%.

Total interest for the year is $150.

To find:

Amount invested on each rate.

Solution:

Suppose x be the amount invested at 7%. Then,

The amount invested at 8% = 2x

The amount invested at 9% = 3x

Total interest for the year is $150.

[tex]x\times \dfrac{7}{100}+2x\times \dfrac{8}{100}+3x\times \dfrac{9}{100}=150[/tex]

Multiplying both sides by 100, we get

[tex]7x+16x+27x=15000[/tex]

[tex]50x=15000[/tex]

Dividing both sides by 50, we get

[tex]x=\dfrac{15000}{50}[/tex]

[tex]x=300[/tex]

So, the amount invested at 7% is [tex]300[/tex].

The amount invested at 8% is

[tex]2(300)=600[/tex]

The amount invested at 9% is

[tex]3(300)=900[/tex]

Hence, the stockbroker invested $300 at 7%, $600 at 8%, and $900 at 9%.

Answer:

[tex]v - 0.06v[/tex] and [tex]0.94v[/tex]

Step-by-step explanation:

Given

[tex]Acreage = v[/tex]

[tex]Decrement = 6\%[/tex]

Required

Determine the new acreage

Because a reduction occur, the new acreage can be calculated using:

[tex]New = Acreage - Decrement * Avreage[/tex]

[tex]New = v - 6\% * v[/tex]

[tex]New = v - 0.06 * v[/tex]

[tex]New = v - 0.06v[/tex] ------ (1)

Evaluate the expression

[tex]New = 0.94v[/tex] ---- (2)

Step-by-step explanation:

20°+120°+I°=180°

I=40°

using sine rule,

I/sin I=x/sinX

12/sin40=x/sin20

x=12sin20/sin40

x=6.4

using similarly and enlargement,

we have, cw/cp=y/120

Answer:

5x+2y=15

y=-3x+4

Substituting the value of y in the first equation..

5x+2(-3x+4)=15

5x-6x+8=15

x = -7

So, y = -3(-7)+4

y = 25

Answer:

No, too many dots to the left of 0.5

And the average proportion is about 0.39, close to 0.4

Step-by-step explanation:

There are way more dots to the left of 0.5 than there are to the right of 0.5

And there are nowhere near enough dots right on 0.5 to make up for that.

So we can tell just from looking that these dots don't average out to 0.5

If you actually count the dots  and add up the values of all the dots:

1 x 0.1        =           0.1

3 x 0.2      =           0.6

9 x 0.3       =          2.7

8 x 0.4       =          3.2

6 x 0.5       =          3.0

2 x 0.6       =          1.2

1 x 0.7        =         0.7

30 proportions      11.5   Total of All Proportions

11.5/30 = 0.38333333... , a lot closer to 0.4 than to 0.5

~11.31
