Use compatible numbers to estimate the quotient 252÷3

ICE Princess25 [194]

Answer:

The value of the given expression is 84.

Step-by-step explanation:

The given expression is

$\frac{252}{3}$

The number 252 can be written as 240+12, because 24 can easily divisible by 3.

The compatible numbers are 240 and 12

$\frac{252}{3}=\frac{240+12}{3}$

$\frac{252}{3}=\frac{240}{3}+\frac{12}{3}$

$\frac{252}{3}=80+4$

$\frac{252}{3}=84$

Therefore the value of the given expression is 84.

STatiana [176]

Answer:

$\Delta s \approx 334.545\,m$

Step-by-step explanation:

Let assume that Earth is a sphere, the following trigonometric diagram is constructed and presented below. The central angle is given by this inverse trigonometric equation:

$\theta = 2\cdot \cos^{-1} \left(\frac{r}{r+h} \right)$

$\theta = 2\cdot \cos^{-1}\left(\frac{4000\,mi}{4000\,mi+3.5\,mi} \right)$

$\theta = 4.792^{\circ}$

The distance of the portion of Earth that can be seen is:

$\Delta s = \frac{4.792^{\circ}}{360^{\circ}}\cdot (2\pi)\cdot (4000\,mi)$

$\Delta s \approx 334.545\,m$

QUESTION 3 Find the interest. Round to the nearest cent. $1850 at 8% for 14 months

Genrish500 [490]

Answer:

$I=\$172.67$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$I=P(rt)$

where

I is the Interest Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=14/12\ years\\ P=\$1,850\\r=0.08$

substitute in the formula above

$I=1,850(0.08(14/12))$

$I=\$172.67$
