The age of a father is three times that of his son. In ten year's time their ages will add up to 68 years. If the son is x years

Elodia [21]

Answer:

46 and 22

Step-by-step explanation:

let the father b (f) and d son is (s)

f=3s.....(1)

(f+10) +(s+10)=68 .... (2)

substitute f=3s in equation (2)

we have

(3s+10)+(s+10)=68

4s+20=68

4s=68-20

4s=48

s=12 .......(3)

substitute (3) in (1)

f=3*12

which f=36

in 10 year time

f+10 =46

s+10=22

The distribution of the number of graduate students over the past 13 years in the math department was: 1 69 2 445 3 347 4 0269 5

Sergio [31]

Answer:

largest number os students = 73

smallest number of students is 16

Step-by-step explanation:

Distribution of student over the period of 13 year is given in the following table

first column represent the stem which are on tens digit while column 2 represent the leaf which are on one digit.

1 6 9

2 4 4 9

3 3 4 7

4 0 2 6 9

7 3

hence the graduate student number is calculated as

16, 19, 24,24,29, 33, 34,37,40,42,46,49,73.

hence from the obtained data largest and smallest number of students over a period of 13 year can be calculate

Anarel [89]

Answer:

C. Only Henry's proof is correct.

Step-by-step explanation:

Amy's "proof" leaves out the steps that Henry's proof puts in. Only Henry's proof is correct.

Amy's proof has no reasoning to support her "therefore ..." and no reasoning to support her conclusion that angles 4 and 2 are equal. Nothing in her proof supports her conclusion that the transitive property of equality can be applied.

Can someone pls explain to me how to Order the following numbers in an ascending order?

SpyIntel [72]

Answer:

swap 1,2; swap 3,4

Step-by-step explanation:

Put the numbers in scientific notation, with one digit left of the decimal point.

The number with the largest exponent is largest.

If exponents are equal, the number with the largest mantissa is the largest.

Here, the exponents are already in order, so you need only order the mantissas for each exponent. Ascending order is ...

$1.22\times10^{-8}\\3.61\times10^{-8}\\5.5\times10^{-6}\\7.49\times10^{-6}\\2.87\times10^{-5}$
