Type a digit that makes this statement true.<br> 7,176,260 is divisible by 3.<br> Submit

Margarita [4]

Answer:

1, 4 or 7

Step-by-step explanation:

The divisibility rule/shortcut for 3 is that the sum of its digits is divisible by 3. So, you currently have 29 (7+1+7+6+2+6+0), and you have to make that number divisible by 3.

adding 1 gets you 30, which we know is divisible by 3.

then, instead of trying every digit, we can note that

30 , 33 , 36 , 39 ....

are divisible by 3.

But the most we can add to the sum of 29 is 9 (because that is the highest digit possible)--so numbers above 38 are irrelevant

so, we want to find out if we can make 29 into 30, 33, or 36

adding 1 to 29 = 30

adding 4 to 29 = 33

adding 7 to 29 = 36

So, by making the first digit 1 , 4 , or 7, you make the number divisible by 3 (making the sentence true)

Answer:

Adam scored 60, Brandon scored 66, Chen scored 74, Damion scored 75, and Erica scored 75.

Step-by-step explanation:

Since five friends took the maths test, and Adam, Brandon, and Chen together together scored 200 marks; Brandon, Chen and Damion together scored 215; Chen, Damion and Erica together scored 224; and Damion and Erica scored more than Chen; While the five of them together scored 350 marks, to determine what are their individual scores the following calculations must be done:

Adam + Brandon + Chen = 200

Damion + Erica = 150

Brandon + Chen + Damion = 215

Adam + Erica = 135

Chen + Damion + Erica = 224

Adam + Brandon = 126

Adam + Brandon = 126 + Chen = 200

Chen = 200 - 126

Chen = 74

Damion and Erica scored more than Chen

Chen + Damion + Erica = 224

74 + Damion + Erica = 224

Damion + Erica = 150

Damion = 75

Erica = 75

Brandon + Chen + Damion = 215

Brandon + 74 + 75 = 215

Brandon = 215 - 74 - 75

Brandon = 66

Adam = 350 - 75 - 75 - 74 - 66

Adam = 60

Therefore, Adam scored 60, Brandon scored 66, Chen scored 74, Damion scored 75, and Erica scored 75.

$1,000 is invested at a rate of 3.25%, compounded annually. Identify the compound interest function that models the situation. T

Ulleksa [173]

The compounded interest function that models the situation is: $A=P(1+ \frac{r}{n} )^{nt}$
where
$A$ is the final amount of money after $t$ years.
$P$ is the initial investment.
$r$ is the interest rate in decimal form.
$n$ is the number of times the interest is compounded per year.
$t$ is the time in years.

We know for our problem that $P=1000$ and $t=8$ . To convert the interest rate to decimal form, we are going to divide the rate by 100%:
$r= \frac{3.25}{100}$
$r=0.0325$
We also know that the interest is compounded anally, so it is compounded 1 time per year; therefore, $n=1$ .
Lets replace the values in our formula to find the final amount after 8 years:
$A=P(1+ \frac{r}{n} )^{nt}$
$A=1000(1+ \frac{0.0325}{1} )^{(1)(8)}$
$A=1000(1+ 0.0325 )^{8}$
$A=1291.58$

We can conclude that since we are dealing with compound interest we must use the function $A=P(1+ \frac{r}{n} )^{nt}$ . Also, after 8 years the balance in the account will be $1291.58
