when factorised 16c-12cg is
4c Is common to both 16c and 12cg
so we bring out 4c
4c( 4- 3g)
question 4
from what I can see through the diagram the hypotenuse is 15 and the adjacent is 9 and we're asked to find titre
so we use the relation cos titre= adjacent/hypotenuse
cos titre= 9/15
cos titre=0.6
therefore titre is cos inverse of 0.6 which is 53.13
Alicia invests £175 for n years into a savings account. Alicia was paid 2.5% per annum compound interest. At the end of the n years Alicia had £316.53 in the savings account. Work out the value of n.
The number of years it took the amount invested to accrue to £316.53 is 23.7 years.
What is compound interest?Compound interest is when both the money invested and the money already accrued earn interest.
What is the number of years?Number of years = in(fv / pv) r
FV = future value
PV = present value
r = interest rate
(IN 316.53 / 175) / 0.025 = 23.7 years

Is (x-4) a factor of (x3 +x2 -16x-16)?
SHOW FULL WORK
Answer:
f(x)= x^3+x^2-16x-16
By the factor theorem,
f(4)=4^3+4^2-(16×4)-16 =0
Since f(4)=0, (x-4) is a factor of x^3+x^2-16x-16

Answer:
3 • (2x - 7) - (x + 4) = 0
then do 3.1 Pull out like factors :
5x - 25 = 5 • (x - 5)
5 • (x - 5) = 0
4.2 Solve : x-5 = 0
Add 5 to both sides of the equation :
x = 5
Step-by-step explanation:
Answer:
[tex] \sf \: x = 5[/tex]
Step-by-step explanation:
Given equation,
→ 3(2x - 7) = 5 - (1 - x)
Now the value of x will be,
→ 3(2x - 7) = 5 - (1 - x)
→ 6x - 21 = 5 - 1 + x
→ 6x - x = 4 + 21
→ 5x = 25
→ x = 25/5
→ [ x = 5 ]
Hence, the value of x is 5.
what is the distance between (-6,8) and (-3,9)
A) 4
B) 6
C) square root of 10
D) square root of 15
Answer:
I would say it is close to 4, but not 4.
Step-by-step explanation:
So I rounded the distance between the 2 plots with a line, and I got either 3.8 or 3.1
square root of 10 = 3.1
square root of 15 = 3.8
The picture is my graph I used to base it, so I would generally consider how close it is to 4 saying C. Square root of 10.
(I only chose 3.1 because I went up on the graph 3 squares with my line. It did not quite reach. I went 1/10(0.1) of a whole up further, and it resulted in the square root of 10 choice.)

Question 18 Solve simultaneously x + y = 6 6x - 5y = 14
Answer:
(4, 2)Step-by-step explanation:
Given system:
x + y = 6 6x - 5y = 14 Solve by elimination, multiply the first equation by 5 and add up equations:
5x + 5y + 6x - 5y = 5*6 + 1411x = 44x = 4Find y:
4 + y = 6y = 6 - 4y = 2Answer:
x = 4
y = 2
Step-by-step explanation:
Rewrite x + y = 6 to make y the subject:
⇒ y = 6 - x
Substitute y = 6 - x into 6x - 5y = 14 and solve for x:
⇒ 6x - 5(6 - x) = 14
⇒ 6x - 30 + 5x = 14
⇒ 11x - 30 = 14
⇒ 11x = 44
⇒ x = 4
Substitute x = 4 into x + y = 6 and solve for y:
⇒ 4 + y = 6
⇒ y = 2

The Pie Chart is the best type of chart that could be used to represent the distribution of this data.
What is a Pie Chart?A pie chart is a type of circular statistical graph used for the representation of a data set. The graph's segments are proportionate to the percentage of the total in each group.
However, the proportion of each portion of the pie chart is proportional to the number of the group as a whole.
The full pie chart represents 100% of the whole, whereas The pie portion represents sections of the total.Therefore, from the given information contains many data sets, each data can be represented in each portion to make a full Pie Chart.

10. A company finds that 45% of first-time visitors to its website do not buy any of its products. If there are 75 first-time visitors on a given day, what is the probability that exactly 36 of them buy a product? Round your answer to the nearest thousandth. Answer choices: 0.044 0.080 0.450 0.550
Using the binomial distribution, it is found that the probability that exactly 36 of them buy a product is of 0.044.
For each first-time visitor, there are only two possible outcomes, either they buy a product, or they do not. The probability of a first-time visitor buying a product is independent of any other first-time visitor, hence the binomial distribution is used to solve this question.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem:
45% of first-time visitors to its website do not buy any of its products, hence 55% buy, that is, p = 0.55.There are 75 first-time visitors on a given day, hence n = 75.The probability that exactly 36 of them buy a product is P(X = 36), hence:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 36) = C_{75,36}.(0.55)^{36}.(0.45)^{39} = 0.044[/tex]

Answer:
240 cm²
Step-by-step explanation:
Split the shape into a trapezoid (top half) and a rectangle (bottom half).
Area of a rectangle = width x length
⇒ area = 6.5 x 20 = 130 cm²
[tex]\textsf{Area of a trapezoid} = \frac{1}{2}(a+b)h[/tex]
(where a and b are the lengths of the base and top, and h is the height)
⇒ [tex]\textsf{area} = \frac{1}{2}(20+20)\times5.5[/tex]
⇒ area = 110 cm²
Total area = area of rectangle + area of trapezoid
⇒ area = 130 + 110 = 240 cm²

Calvin’s credit card computes finance charges using the daily balance method. His card has a billing cycle of 30 days and an APR of 14. 75%. The following table details Calvin’s transactions in the month of September. Date Amount ($) Transaction 9/1 716. 54 Beginning balance 9/7 84. 94 Purchase 9/12 15. 69 Purchase 9/20 200. 00 Payment What will Calvin’s starting balance be next month? a. $617. 17 b. $624. 74 c. $625. 91 d. $623. 52.
Answer:
c. $625. 91
Step-by-step explanation:
The average daily balance totals each day's balance for the billing cycle and divides by the total number of days in the billing cycle. Then, the balance is multiplied by the monthly interest rate to assess the customer's finance charge—dividing the cardholder's APR by 12 calculates the monthly interest rate.
Add. Simplify your answer.
Step-by-step explanation:
Add the ones with like terms.
which means the ones with things in common.
4/5x^2 + 1/4x^2 i'm adding this first because we have x^2 on both sides.
(4/5 + 1/4)x^2
= (5+16/20)x^2
= (21/20)x^2
the next terms are those with x as common.
(1/4 +- 1/5)x...take the sign into consideration while dealing with the terms within the equations.
=(1/4 - 1/5)x
=(5 - 4/ 20)x
= (1/20)x
= (1 × x) / 20
= x/20.
last ones are the constant terms(numbers)
1/6 + 2/3
=12 + 3 / 18
= 15/18...we can simplify this one as well.
= 5 × 3 / 6 × 3
= 5/6.
Now write all the results as a one equation.
descending order starting from the highest degree which is 6/5x^2 --> 1/20x ---> 5/6.
21/20x^2 + x/20+ 5/6.

Raj purchased an article for Rs400 and sold it for Rs 420. Find the lrofit or loss percent
Given :-
Raj purchased an article for Rs420 .He sold it for Rs 420 .To Find :-
The profit or loss percentage .Solution :-
Here the cost price for Raj is Rs 400 and Selling price is Rs420 .
Here since SP > CP , so there's a profit .
→ Profit = SP - CP
→ Profit = Rs420 - Rs400
→ Profit = Rs 20
Now we can calculate the profit% as ,
→ Profit/CP * 100
→ Rs 20/ Rs 400 * 100 %
→ 20/4%
→ 5%
Hence the profit is 5% .
I hope this helps .
Answer:
5%Step-by-step explanation:
Cost price of the article = Rs 400
Selling price of the article = Rs 420
As, S.P > C.P
Profit = S.P – C.P
= Rs( 420 – 400)
⠀⠀⠀= Rs 20
So,
Profit percent = (20/400 × 100)%
⠀⠀⠀⠀⠀⠀⠀⠀ = (20/4) %
⠀⠀⠀⠀⠀⠀⠀⠀ = 5 %
