can someone help me please!!!!!!!

Answer:

a) £960

b) £576

Step-by-step explanation:

Hi!

Ok so since the store has a 20% sale we multiply 0.2 to the original amount it would have costed without the sale:

a) [tex]1200*0.2 = 240[/tex]

Then we subtract the number we got from the price:

1200 - 240 = 960

Now we do the same thing but this time add since we are trying to find the price of the table before the sale:

b) [tex]480*0.2 = 96[/tex]

480 + 96 = 576

Please ask me if you have any more questions!

and Have a great day! :)

Answer:

$91.08

Step-by-step explanation:

Interest = $90 × .012 = $1.08

Total amount = $90 + $1.08 = $91.08

Let

Applying the law of indeces for the fraction with radicals, the value of A=3, b=14 and c=-5

In mathematics, the term radical expressions such that contain a square root. In this question, we have fractions at both sides of the equation with radicals.

To solve this question, let's see some laws below that will help us:

[tex] \sqrt[x]{a} = {a}^{ \frac{1}{x} } [/tex]

[tex] \frac{ {a}^{x} }{ {a}^{y} } = {a}^{x - y} [/tex]

[tex] \frac{1}{ {a}^{x} } = {a}^{ - x} [/tex]

From the given equation; the left hand side will be simplified as follows;

[3^(1/7)]÷[3^(1/2)]=[3^[(2-7)/14]=3^(-5/14)

And the right hand side will be simplified as follows;

1÷[A^(c/b)]=A^-(c/b)

Hence, by comparing both sides of the equation after simplifying the fractional radicals, the value of A is 3, b is 14 and c is -5.

Answer:

$2,000

Step-by-step explanation:

Amount invested in Fund A = 6000

Profit rate of return = 5%

Amount of profit = 6000 x 5% = 6000 x 0.05 = $300

Let amount invested in Fund B be $x

Profit amount = 0.01x

Total amount invested is 6000 + x

Total profit in $ = 300 + 0.01x

Total profit in percentage = Total Profit/Total investment x 100

= 4 %

So Total Profit/Total investment = 4/ 100 = 0.04

= (300 + 0.01x) / (6000 + x)  = 0.04

Multiply both sides by (6000 + x)

=> 300 + 0.01x = 0.04(6000 + x)

=> 300 + 0.01x = 240 + 0.04x

==> 300 - 240 = 0.04x - 0.01x

=> 60 = 0.03x

x = 60/0.03

x = $2,000

Amount invested in Fund B = $2,000

Step-by-step explanation:

Fund A

$6000 returned a 5% profit. that means it had at the end 105% of the original investment

the formally correct way

100% = 6000

1% = 100%/100 = 6000/100 = $60

5% = 1%×5 = 60×5 = $300

in short, if we knew what we are doing, we could have simply calculated 6000 × 0.05 = $300.

and by the way, 6000 × 1.05 = $6300. which is the current balance of the account (investment plus the returned profit). but we don't need this here. this is just FYI.

Fund B

x returned 1% profit.

Fund A + Fund B

6000 + x returned 4% profit.

so, we have

6000×0.05 + x×0.01 = (6000 + x)×0.04

300 + 0.01x = 240 + 0.04x

60 + 0.01x = 0.04x

60 = 0.03x

x = 60/0.03 = $2000

so, he invested $2000 into fund B.

To determine  probability with replacement, It uses sampling with replacement. In other words, you want to determine the likelihood of an event in which you choose a ball, card, or other object from a set of options and then swap it out after each choice.

Example:

Consider a scenario in which you wished to sample two people from a population of seven.

Those people are:

John, Jack ,Qiu, Tina, Hatty, Jacques, Des

Their names could be placed in a hat. If you sample with replacement, you would pick one name, put it back in the hat, and then pick a different name. Your two-name sample has the following potential outcomes:

John, John

John, Jack

John, Qui

Jack, Qui

Jack Tina

…and so on.

The two products you sample with replacement are independent. In other words, the outcome of one has no bearing on the other. The odds of picking the first name are 1/7, and the odds of picking the second name are 1/7.

P(John, John) = (1/7) * (1/7) = .02.

P(John, Jack) = (1/7) * (1/7) = .02.

P(John, Qui) = (1/7) * (1/7) = .02.

P(Jack, Qui) = (1/7) * (1/7) = .02.

P(Jack Tina) = (1/7) * (1/7) = .02.

Answer:

-1/2; take both points which equals to -1/2

Step-by-step explanation:

Answer:

39% of 80 = 39.2

74% of 240 = 177.6

91% of 82 = 74.62

66% of 160 = 105.6

9% of 71 = 63.9

126% of 80 = 100.8

234% of 145 = 339.3

97.9% of 39 = 38.181

52% of 57.9 = 30.108

33% of 15.3 = 5.049

Step-by-step explanation:

In order to find the percentage of each equation, we will use the first one as an example. We take the 39%, and convert it to 0.39 and get rid of the %. Then, "of" means multiplication.

So, we have:

0.39 x 80 = 39.2

The price per share after 5 hours is $28.32

The price per share after 23 hours is $-2.1

Given,

A​ company's stock began the day at ​$ 36.77per share.

and, price drops be $1.69 each hour.

To find the what is the price per share after 5hours

and, also find what will be after 23 hours rate continues?

Now, According to the question:

The price of the company's stock is initially at $36.77 per share. Each hour the price drops by $1.69. This condition can be modeled by the function:

P(t) = 36.77 - 1.69t

Where t is the time in hours.

The sign means the function is decreasing as time passes.

When t=5 hours, the price will be:

P(5) = 36.77 - 1.69 × 5 = 28.32

The price per share after 5 hours is $28.32

Now find the price when t=23 hours

P(23) = 36.77 - 1.69 × 23 = - 2.1

The price per share after 23 hours is $-2.1

Hence, The price per share after 5 hours is $28.32

The price per share after 23 hours is $-2.1

2. we find the gradient between the two points using this equation m=[tex]\frac{y2-y1}{x2-x1}[/tex]

3. we plug the value in the equation

4. m = 5/2

5. equation of a straight line is y = mx +c

-where c is the intercept of the graph and m is the gradient

-4=5/2(0)+c

c =-4

therefore [tex]y=\frac{5}{2}x -4[/tex]

The equation is c = 31 + 0.13x and total cost on driving 180 miles is $54.4.

Firstly we will form the equation using one time charge and the product of number of miles and charge per mile. Then we will keep the value in equation to find the total cost.

Forming the equation -

c = 31 + 0.13x

Keep the value of x in formula for calculation of total cost.

c = 31 + 0.13×180

Performing multiplication on Right Hand Side of the equation

c = 31 + 23.4

Performing addition on Right Hand Side of the equation

c = $54.4

Thus, the equation for calculation of total cost is c = 31 + 0.13x and total cost is $54.4.

The estimate of the impact that a successful preventive program might have can be derived from

attributable risk.

In epidemiology, attributable risk or excess risk is a phrase equivalent with risk difference, which has also been used to express the attributable proportion among the exposed and the population.

Attributed risk assists in determining how much of an outcome is attributable to a certain risk factor (i.e., an estimate of the excess risk) in a population exposed to that factor.

The rate (percentage) of a health result (illness or death) in exposed persons that can be linked to the exposure is known as the attributable risk (AR). Attribitable risk measures how much more common a result is in absolute terms among the exposed than the non-exposed.

No, Hannah is incorrect.

We are given the expression 42*19.

Hannah got the solution by multiplying 40*10 and 2*9 and then adding the values.

This can be done by using distributive property, which is given by:-

(a + b)(c + d) = ac + ad + bc + bd

We can write,

42*19 = (40 + 2)(10 + 9) = 40*10 + 40*9 + 2*10 + 2*9

Hence, the answer is not just 40*10 + 2*9 but 40*10 + 40*9 + 2*10 + 2*9.

An angle bisector is a bisector that bisect an angles into two equal parts.

Therefore, EF is the angle bisector of ∠EFG.

The bisector divides the ∠EFG equally into ∠EFH and ∠HFG.

Hence,

∠EFH  = ∠HFG

m∠HFG = 80°

m∠EFH  = 80°

m∠EFG = 80 + 80
