Answer:

$42

Step-by-step explanation:

This is an example of a percentage decrease.

To work out the percentage decrease you would first need to convert the percentage of 25% into a decimal. You can do this by dividing the percentage  of 25 by 100, this gives you 0.25. This is because percentages are out of 100.

The next step is to minus 0.25 from 1, this gives you 0.75. This is because we are working out the percentage decrease.

To work out the discounted price you would multiply the amount of $56 by 0.75, this gives you $42.

1) Divide 25 by 100.

[tex]25/100=0.25[/tex]

2) Minus 0.25 from 1.

[tex]1-0.25=0.75[/tex]

3) Multiply $56 by 0.75.

[tex]56*0.75=42[/tex]

Answer:

520

Step-by-step explanation:

80 times 6.5 = 520

so she can type 520 words in 6.5 mins

Answer:

The answer would be 520

Step-by-step explanation:

We have 80 words per minutes:)

It asks how much words can we type in 6.5 minutes.

well if we do 80 words per minute we can multiply the values

80 words x 6 minutes is 480

But wait we have .5 left

so we do 80 divided by 2 and get 40

then we go 480 plus 40 and get 520

we could have straight out multiplyed it and got this but thats no fun.

520 Words for 6.5 mins :)

Answer:

Garret placed the treasure at the right place.

Step-by-step explanation:

The Cartesian plane can be used to locate the position of any given point with a coordinate. It consists of two numbered lines perpendicular to each other and intersecting at point zero of the lines.

From the statements given, 5 units from x-axis is not the same as 5 units on x-axis. Also, 3 units from y-axis is not the same as 3 units on y-axis.

So, distance 5 units from x-axis implies that a point 5 units after the x-axis. And also, distance 3 units from y-axis means 3 units after the y-axis.

With these conditions of the coordinate of the treasure, Garrett placed the treasure at the right place.

Answer:

max wil sell 52 because the first hour he sold 12 5hours -1 hour = 4 hour

4 hour × 10 p/h= 40

max sold 12+40 =52

leah will sell 58 because the first hour she sold 8

5hours - 1hour = 4 hours

4hours× 10 glasses p/h = 40

leah sold 40+8 =48 glasses

If Max and Leach sold 10 glasses each hour then after Max sold 52 glasses after 5 hours and Leach sold 48 glasses after 5 hours because it forms arithmetic progression.

It is a type of sequence in which each number have a common difference from the other number. The nth term of an arithmetic progression can be calculated as a+(n-1)d.

For Max we have been given that the first term is 12 and the common difference is 10.

After 10 hours the glasses which Max will sell as 12+(5-1)*10

=12+40=52 glasses

For Leach we have been given that the first term is 8 and the common difference is 10.

After 5 hours the glasses which Leach will sell as 8+(5-1)*10

=48 glasses.

Hence the number of glasses will be 52 and 48 glasses for Max and Leach.

At the start, the tank contains

(0.25 lb/gal) * (100 gal) = 25 lb

of sugar. Let [tex]S(t)[/tex] be the amount of sugar in the tank at time [tex]t[/tex]. Then [tex]S(0)=25[/tex].

Sugar is added to the tank at a rate of P lb/min, and removed at a rate of

[tex]\left(1\frac{\rm gal}{\rm min}\right)\left(\dfrac{S(t)}{100}\dfrac{\rm lb}{\rm gal}\right)=\dfrac{S(t)}{100}\dfrac{\rm lb}{\rm min}[/tex]

and so the amount of sugar in the tank changes at a net rate according to the separable differential equation,

[tex]\dfrac{\mathrm dS}{\mathrm dt}=P-\dfrac S{100}[/tex]

Separate variables, integrate, and solve for S.

[tex]\dfrac{\mathrm dS}{P-\frac S{100}}=\mathrm dt[/tex]

[tex]\displaystyle\int\dfrac{\mathrm dS}{P-\frac S{100}}=\int\mathrm dt[/tex]

[tex]-100\ln\left|P-\dfrac S{100}\right|=t+C[/tex]

[tex]\ln\left|P-\dfrac S{100}\right|=-100t-100C=C-100t[/tex]

[tex]P-\dfrac S{100}=e^{C-100t}=e^Ce^{-100t}=Ce^{-100t}[/tex]

[tex]\dfrac S{100}=P-Ce^{-100t}[/tex]

[tex]S(t)=100P-100Ce^{-100t}=100P-Ce^{-100t}[/tex]

Use the initial value to solve for C :

[tex]S(0)=25\implies 25=100P-C\implies C=100P-25[/tex]

[tex]\implies S(t)=100P-(100P-25)e^{-100t}[/tex]

The solution is being drained at a constant rate of 1 gal/min; there will be 5 gal of solution remaining after time

[tex]1000\,\mathrm{gal}+\left(-1\dfrac{\rm gal}{\rm min}\right)t=5\,\mathrm{gal}\implies t=995\,\mathrm{min}[/tex]

has passed. At this time, we want the tank to contain

(0.5 lb/gal) * (5 gal) = 2.5 lb

of sugar, so we pick P such that

[tex]S(995)=100P-(100P-25)e^{-99,500}=2.5\implies\boxed{P\approx0.025}[/tex]

Answer:

Step-by-step explanation:

1) Your calculator can evaluate f(-5) for you. It will be ...

  f(-5) = (1/3)^(-5) -3 = 243 -3

  f(-5) = 240

So, a point on the graph is (-5, 240).

Other points on the graph will be (1, -8/3), (0, -2), (-1, 0), (-2, 6).

__

2) The given function f(x) can be written as ...

  f(x) = (1/3)^x -3 = (3^-1)^x -3 = 3^-x -3

So, the transformed function is transformed by adding 1, changing the horizontal asymptote from -3 to -2. The whole graph is translated upward one unit. Each of the above-listed points will have 1 added to its y-value.

[tex]\frac{1}{10} \£[/tex]

Step-by-step explanation:

We know that £1 equals 100p.

Knowing this relation, we can use the rule of three

[tex]30p \times \frac{ \£1}{100p} =0.3 \£[/tex]

Then, we form the fraction

[tex]\frac{0.3 \£}{\£ 3.00} =\frac{3}{30} =\frac{1}{10} \£[/tex]

Therefore, the fraction of of £3.00 is

Hey there! I'm happy to help you out!

Let's think of our original price ($P) as 100%. This is also the same thing as 1 because 100% is one whole thing.

Now, we see that he got a 15% off discount. Now, we just subtract 15% from 100% to see what percent he actually payed.

100%-15%=85%

This means that $R is 85% of $P (100%).

Answer A is not correct because 0.85% is less than 1%, which is not 85%.

Answer B is not correct either because 0.15% is also less than 1%.

Answer C is correct because $R is 85% of the original cost.

I hope that this helps! Have a wonderful day!

Answer:

Mr. Otsuki could have:

10 $20 bills

5 $10 bills

10 $5 bills

but there are many other ways.

Step-by-step explanation:

We already know that Mr. Otsuki already has at least $245.

10 $20 bills - $200

at least 9 $5 bills - $45

300 - 245 = 55

55 can be made up in many different ways

5 tens + 1 five

9 fives+ 1 tens

4 tens + 3 fives

5 fives+ 3 tens

2 tens + 7 fives

So there are like five answers to this question:

A.

10 $20 bills

5 $10 bills

10 $5 bills

B.

10 $20 bills

1 $10 bills

9 $5 bills

I took the test and I got 100%.

Answer:

0.991

Step-by-step explanation:

Let Q be probability none of the 4 are vaccinated.

Let P be probability that at least 1 is vaccinated.

P = 1 - Q

Now if 69% are vaccinated, then 31% are not vaccinated.

Thus any given person has a probability of 0.31 of not being vaccinated.

Q = (0.31)^4 = 0.00924

P = 1 - 0.00924 = 0.991

Answer:

13/50; 13/50

Step-by-step explanation:

a): Theoretical=# of favorable outcomes/# of total outcomes

To find the total, add 21+26+25+28, which is 100

A has a frequency of 26.

That would be 26/100, which is also 13/50

b): Experimental probability is based on the amount of times the spinner is spun. Since A is the only vowel in "MATH", we would take that fraction and multiply it by 100, or the number of times.

13/50*100=13*2=26

Put that over 100, which would be 26/100, which is also 13/50.

Hope this helped! Have a good rest of your day!

Answer:

  4^(11/20)

Step-by-step explanation:

The applicable rule of exponents is ...

  (a^b)/(a^c) = a^(b-c)

Using that here, we have ...

  4^(3/4)/4^(1/5) = 4^(3/4 -1/5)

  = 4^(15/20 -4/20) = 4^(11/20)

Answer:

Assuming no compounding, given an interest rate of 5%, after 5 years the $300 dollars become:

300*(1+5%)^5= $382.884469

By saving $250 instead,

250*(1.05)^5=319.07039

The difference is 382.8845-319.0704= 63.8141

Step-by-step explanation:

The formula is FV=PV*(1+r%)^T

Where:

FV- future value

PV- present value

r%- interest rate

T- Time (usually in years)
