A pair of numbers has an HCF (Highest Common Factor) of 7 , and an LCM (Lowest Common Multiple) of 42 . What is the pair of numbers
Answer:
14 and 21
Step-by-step explanation:
This is not an easy question, but luckily we can have an idea to solve this.
In this case, we need to apply the relation between HCF and LCM, which is the following:
HCM * LCM = Number 1 * Number 2
In other words, the multiplication of both factors is equal to the multiplication of the given numbers that we are looking for. Now, we do not know the numbers but we can have an idea of which numbers can be when we calculate the product of the factors:
HCM * LCM = 42 * 7 = 294
We know that the products should result 294, and if the HCM is 7, means that both numbers can be divided by 7 as the highest factor, so, let's write the multiple of 7:
Multiples of 7:
7, 14, 21, 28, 35, 42, 49, 56, 63, 70
With these we can have an idea, if 42 * 7 = 294, all we just need is to find others two numbers that the result gives 294:
14 * 7 = 98
14 * 21 = 294
14 and 21 could be the numbers, but let's confirm writting their multiples
HCM of 14: 1, 2, 7, 14
HCM of 21: 1, 3, 7, 21
LCM of 14: 14, 28, 42, 56, 70
LCM of 21: 21, 42, 63, 84
As you can see, The HCM and LCM of 14 and 21 are 7 and 42, therefore the pair of numbers are:

How many distinct permutations can be made from the letters of the word
“INDEPENDENCE”?
if anyone could answer, thank you (^-^)
Answer:
360
Step-by-step explanation:
Word INDEPENDENCE has I−1, N−3, D−2, E−4, P−1, C−1
There are six different letters in INDEPENDENCE
Now according to the question, we need to form 4 different letter words, So the selection of 4 words out of 6 is
[tex]^{6}C _{4}[/tex]
and making its arrangements
So total number of ways is
[tex]^{6}C _{4}[/tex] ×4!=360
The number of distinct permutations can be made from the letters of the word “INDEPENDENCE” is; 1663200
We are given the word INDEPENDENCE and it has;
I − oneN - threeD − twoE - fourP - oneC - oneThus, we see that there are six different letters and 12 letters in total in INDEPENDENCE
Now from the question, the distinct permutations that can be formed is;
12!/(3! × 2! × 4!) = 1663200

A new car is purchased for $17,000 and over time its value depreciates by one half every 3 years. What is the value of the car 19 years after it was purchased, to the nearest hundred dollars?
Answer:
The answer is "$238".
Step-by-step explanation:
Current worth[tex]= \$ 17,000[/tex]
depreciates by [tex]\frac{1}{2}[/tex] in 3 years.
time= 19 years
depreciates rate=?
Using formula:
[tex]\to \text{Worth= Current worth}(1- \frac{\text{depreciates rate}}{100})^{time}[/tex]
[tex]\to A_t=A_0(1-\frac{r}{100})^t[/tex]
calculates depreciate value in 3 year [tex]= \frac{1}{2} \times 17,000[/tex]
[tex]= 8,500[/tex]
so,
[tex]A_t=8,500\\\\A_0=17,000\\\\t=3\ years[/tex]
[tex]\to A_t=A_0(1-\frac{r}{100})^t\\\\\to 8,500= 17,000(1-\frac{r}{100})^3\\\\\to \frac{8,500}{17,000}= (1-\frac{r}{100})^3\\\\\to \frac{1}{2}= (1-\frac{r}{100})^3\\\\\to (\frac{1}{2})^{\frac{1}{3}}= (1-\frac{r}{100})\\\\\to 0.793700526 = (1-\frac{r}{100})\\\\\to \frac{r}{100} = (1-0.793700526)\\\\\to \frac{r}{100} = (1-0.8)\\\\\to r= 0.2 \times 100 \\\\\to r= 20 \%[/tex]
depreciates rate= 20%
[tex]\to \text{Worth= Current worth}(1- \frac{\text{depreciates rate}}{100})^{time}[/tex]
[tex]= \$ 17,000 (1- \frac{20}{100})^{19}\\\\= \$ 17,000 (1-0.2)^{19}\\\\= \$ 17,000 (0.8)^{19}\\\\= \$ 17,000 \times 0.014\\\\= \$ 238[/tex]
