Answer:

5/8

Step-by-step explanation:

28x + 4 can be factorised because 28 is a multiple of 4

so it can become

4(7x+1)

35x + 5 can be also factorised because 35 is a multiple of 5

5(7x+1)

we can now rewrite the expression as

6/4(7x+1) * 5(7x+1)/12

we can “eliminate” the two 7x+1 and simplify 6 with 12

so it remains

1/4 * 5/2 = 5/8

Kate reads books that were 240, 450, 240, 160, 165, 170, 180 pages long. What are the mean median and mode and which one describ

ser-zykov [4K]

Order set...{160,165,170,240,240,450}

The "mean" is the arithmetic average of the elements...

mean=(160+165+170+240+240+450)/6=237.5

The "median" if the set has an odd number of terms is the middle term, if the set has an even number of terms, it is the average of the middle two terms.

In this case the number of elements is even and the middle two terms are 170 and 240 so:

median=(170+240)/2=205

The "mode" is the term which appears the most in the set, so in this case:

mode=240

If y = 7x − 5, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?

LenaWriter [7]

Given equation is y =7x - 5.

Let's plug in the values of x's to get their corresponding values of y's.

Let's plug in x = -5. So,

y = 7( -5) - 5 = -35 - 5 = -40

So, the first order pair is (-5, -40)

Hence, the first choice is not correct.

For x = 2, y = 7 (2) - 5 = 14 - 5 = 9.

Second order pair is (2, 9). So, second choice is also not correct.

Now for x = 0, y = 7(0) - 5 = - 5.

So, the third order pair is (0, -5).

Let's plug in x = -3 to check the third order pair list as we have already got two order pair (0, -5) and (2, 9) from that list.

For x = -3, y = 7(-3) - 5 = - 21 - 5 = -26.

Hence the correct choice is {(0, −5), (2, 9), (−3, −26)}.

In a tile game, Kent lost 53.5 points in the first round and 12.9 points in the second round.

So 53.5 + 12.9 =66.4 then thats a. -66.4

Find the amount accumulated if 50000 is invested for 20 years at a rate of 7% compounded daily

lys-0071 [83]

The formula for compound interest is given by :

A=P(1+r/n)^(nt)

$A=P(1+\frac{r}{n} )^(nt)$

Here we are given that

P=50000

time(t) = 20 years

rate =7%=0.07

n=365 ( daily)

Plugging in the values in the given formula we get

$A=50000(1+\frac{0.07}{365} ^(365*20)$

Answer : A=202732.78381....
