Can Anyone Please Help Me Which Statement Is Not Correct? (use Estimation To Decide Please)

Answers

Answer 1

Answer:

Step-by-step explanation:

A is correct.

2/3 > 4/8

5/9 > 7/12    This one is close. They are both nearly 1/2, but 9<12 and when you divide something by 9 the remainder is going to be larger than if you divide by 12.

The second one is incorrect.

3/4 > 5/9    5/9 is close to 1/2. Three quarters is much greater than 1/2

3/10 is much smaller than 5/9

The third one is correct. 1/10 and 5/6 are much larger than the two fractions on the right. The right side = 56/60 which is very nearly one. The left side is nowhere near that large. (I did estimate the right side).

The fourth one is correct. 9/10 is much larger than 2/3 and 5/9 is larger than 5/12. 5/9 is over 1/2 and 5/12 is under one half. So the arrow in the fourth one is going the right way.

To help with her retirement savings, Donna has decided to invest. Assuming an interest rate of 3.59% compounded quarterly, how much would she have to invest to have $117,300 after 18 years?

Answers

Answer:

We get the value of Principal amount i.e initial investment = $61640

Step-by-step explanation:

Interest rate r = 3.59% or 0.0359

Compounded quarterly n = 4

Future Amount A = 117,300

Time t = 18 years

We need to find initial investment i,e Principal Amount P

The formula used is: [tex]A=P(1+\frac{r}{n})^{nt}[/tex]

Putting values and finding P

[tex]A=P(1+\frac{r}{n})^{nt}\\117300=P(1+\frac{0.0359}{4})^{4*18} \\117300=P(1+0.008975)^{72}\\117300=P(1.008975)^{72}\\117300=P(1.903)\\P=\frac{117300}{1.903}\\P=61640[/tex]

So, We get the value of Principal amount i.e initial investment = $61640

Answers

Invertible functions are functions whose inverse can be calculated.

The values of the expressions are: [tex]f^{-1}(f(5)) = 5[/tex] and [tex]f(f(5)) = 11[/tex]

The table entry is given as:

x | 5 | 3 | 1 | 18 | 0 | 9

f(x) | 9 | -2 | -5 | -1 | 1 | 11

(a) Calculate f^-1(f(5))

Start by calculating f(5).

From the table, we have:

[tex]f(5) = 9[/tex]

Take inverse function of both sides

[tex]f^{-1}(f(5)) = f^{-1}(9)[/tex]

From the table, the inverse value of 9 is 5.

i.e. [tex]f^{-1}(9) = 5[/tex]

So, we have:

[tex]f^{-1}(f(5)) = 5[/tex]

(b) Calculate f(f(5))

In (a) above, as have:

[tex]f(5) = 9[/tex]

So, the function becomes

[tex]f(f(5)) = f(9)[/tex]

From the table, the value of f(9) is 11.

So, we have:

[tex]f(f(5)) = 11[/tex]

Use the substitution method because we have x= something in terms of y

6y + 9 -y = 4 subtract 9 from both sides

6y -y = 4-9 combine like terms

Step-by-step explanation:

Lines A and B are parallel, with a transversal passing through them.

The properties of two parallel lines and a transversal tells us that angles 5x and 4x+12 must be equal, because they are a pair of alternate exterior angles.

To solve for x, we do 5x=4x+12

Answers

Answer:

m<C = 42°

Step-by-step explanation:

Given:

m<A = (2x - 2)°

m<C = (4x - 6)°

m<DBC = (5x + 4)°

Thus:

m<DBC = m<A + m<C (exterior angle theorem of a triangle)

(5x + 4)° = (2x - 2)° + (4x - 6)°

Solve for x

5x + 4 = 2x - 2 + 4x - 6

Collect like terms

5x + 4 = 6x - 8

5x - 6x = -4 - 8

-x = -12

Divide both sides by -1

x = 12

✔️m<C = (4x - 6)°

Plug in the value of x

m<C = 4(12) - 6 = 48 - 6

m<C = 42°

Step-by-step explanation:

[tex]\angle{DBC }[/tex]=(5x+4)°

[tex]\angle{ A }[/tex]=(2x-2)°

[tex]\angle{C }[/tex]=(4x-6)°

we know that,

[tex]\angle{DBC}[/tex]=[tex]\angle{A}[/tex]+[tex]\angle{C}[/tex]

According to the question,

[tex]\tt{ 5x+4=2x-2+4x-6 }[/tex]

[tex]\tt{ 5x+4=6x-8 }[/tex]

[tex]\tt{ 6x-5x=4+8 }[/tex]

[tex]\bold{x=12 }[/tex]

so,

[tex]\angle{C }[/tex]=(4x-6)°=(4×12-6)°=(48-6)°=42°

Aimee's garbage disposal has 7/8 horse power. Vincent's garbage disposal has 3/5 horse power. How much more power does aimee's garbage disposal have?

Answers

Answer:

Aimee's garbage disposal has 11/40 more power than Vincent's garbage disposal.

Step-by-step explanation:

Aimee's garbage disposal horse power = 7/8

Vincent's garbage disposal horse power = 3/5

All we need is to subtract Vincent's power from Aimee's power.

i.e.

[tex]\frac{7}{8}-\frac{3}{5}[/tex]

Thus,

[tex]\frac{7}{8}-\frac{3}{5}\:=\frac{35}{40}-\frac{24}{40}[/tex]

[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{c}-\frac{b}{c}=\frac{a-b}{c}[/tex]

         [tex]=\frac{35-24}{40}[/tex]

         [tex]=\frac{11}{40}[/tex]

Thus,  Aimee's garbage disposal has 11/40 more power than Vincent's garbage disposal.

The height in feet, h, of a model rocket t seconds after launch is given by the equation h(t) = 3+70t - 16t^2. The average rate of change in h(t) between t = 1 second and t = 3 second is 6. What does the average rate of change tell you about the rocket?​

Answers

Answer:

The average rate of change

[tex]\frac{dh}{d t} = 70 (1) - 16(2t)[/tex]

At   t = 1

[tex]\frac{dh}{d t} = 70 (1) - 16(2t) = 38[/tex]

at t=3



Step-by-step explanation:

Step(I):-

The given function  h(t) = 3+70t - 16t²

                          [tex]\frac{dh}{d t} = 70 (1) - 16(2t)[/tex]

The       [tex]\frac{dh}{d t} = 70 (1) - 16(2t) =0[/tex]

           70 - 32 t = 0

     ⇒   70 = 32 t

   ⇒     [tex]t = \frac{70}{32} = \frac{35}{16}[/tex]

Step(ii):-

The average rate of change in h(t) between t = 1 second and t = 3 second

[tex]\frac{dh}{d t} = 70 (1) - 16(2t)[/tex]

At   t = 1

[tex]\frac{dh}{d t} = 70 (1) - 16(2t) = 38[/tex]

At t = 3

Mia buys ink at the office supply store for a business.

She buys 3 printer cartridges, and the sales tax is 7%. Write an expression

to represent the total cost of ink supplies in two different ways.

Answers

Answer:

The  total cost of the ink supplies can be represented  in two different ways, as follows:

a. 3p (1+r)

b. p * (1+ r) * 3

Step-by-step explanation:

a) Data and Calculations:

Number of printer cartridges bought = 3

Sales tax rate = 7%

The total cost can be represented as:

Total cost = 3p (1+r)

where p = the price of a printer cartridge

and r = the sales tax rate

Alternatively, the total cost can be represented as:

Total cost = p * (1+ r) * 3

b) Whichever expression is used, the total cost derived will remain the same.  The first expression includes the sales tax in the total cost, while the second expression includes the sales tax in the cost of the unit before arriving at the total cost.
