Find the difference. Round your answer to match the less precise measurement. 83 g – 1.8 g 81 g 82 g 80 g 81.2 g

Ivan

Answer:

Option A.

Step-by-step explanation:

The given expression is

$83 g-1.8 g$

We need to find the difference round to the less precise measurement.

Taking out the common factor.

$(83-1.80)g$

$81.2g$

Precise measurement of given expression is 81.2g.

A measurement with more decimal places is more precise and vice versa.

Now, approx the answer to the the nearest whole measure.

$81.2g\approx 81g$

The less precise measurement of given expression is 81g.

Therefore, the correct option is A.

Suppose you invest $3,500 in a savings account that earns 7% Interest, compounded

prohojiy [21]

Given:

Principal = $3,500

Rate of interest = 7% compounded quarterly (4 times in an year)

Time = 6 years

To find:

The amount.

Solution:

The formula for the amount is

$A=P\left(1+\dfrac{r}{n}\right)^{nt}$

Where, P is principal, r is rate of interest, n is number of times interest compounded in an year and t is number of years.

Putting P=3500, r=0.07, n=4 and t=6 in the above formula, we get

$A=3500\left(1+\dfrac{0.07}{4}\right)^{(4)(6)}$

$A=3500\left(1+0.0175\right)^{24}$

$A=3500\left(1.0175\right)^{24}$

$A=5307.54975$

$A\approx 5307.55$

Therefore, the amount after 6 years is $5307.55.
