Volume = length * width * height

Volume = 4.1 * 5.9 * 7.2 ≈ 4 * 6 * 7 = 168

Volume ≈ 168 in³

Answer: C. $168\ in^3$

Step-by-step explanation:

Given: The dimensions of a box are 4.1 inches, 5.9 inches, and 7.2 inches.

We know that the volume of a cuboid is given by :-

$V=length*width*height$

Thus, volume of given box is given by :-

$V=4.1\times5.9\times7.2\approx4\times6\times7...\text{[Round off to the nearest ones]}\\\\\Rightarrow\ V=168\ in^3$

Hence, the estimated volume of the box = $168\ in^3$

Answer:

$18.03$

Step-by-step explanation:

<u>Formula:</u> $a^{2}+b^{2}=c^{2}$

$15^{2}+10^{2}=x^{2}$

$225+100=x^{2}$

$x^{2}=325$

$x = 5\sqrt{13}=18.03$

It takes 32 hours for a motorboat moving downriver to get from pier A to pier B. The return journey takes 48 hours. How long doe

lina2011 [118]

Answer:

Time taken by the un powered raft to cover this distance is T = 192.12 hr

Step-by-step explanation:

Let speed of boat = u $\frac{km}{hr}$

Speed of current = v $\frac{km}{hr}$

Let distance between A & B = 100 km

Time taken in downstream = 32 hours

$32 = \frac{100}{u +v}$

$u + v = \frac{100}{32}$

u + v = 3.125 ------ (1)

Time taken in upstream = 48 hours

$48 = \frac{100}{u -v}$

$u -v = \frac{100}{48}$

u - v = 2.084 ------- (2)

By solving equation (1) & (2)

u = 2.6045 $\frac{km}{hr}$

v = 0.5205 $\frac{km}{hr}$

Now the time taken by the un powered raft to cover this distance

$T = \frac{100}{v}$

Because un powered raft travel with the speed of the current.

$T = \frac{100}{0.5205}$

T = 192.12 hr

Therefore the time taken by the un powered raft to cover this distance is

T = 192.12 hr

Rob coloured 1/4 of a rectangle .what is another way to name 1/4?

mixas84 [53]

another way to name 1/4 is a quarter because 1/4 of 100 is 25 %, so that's why it is called a quarter.

hopefully this helps you :)

Use linear approximation to approximate √25.3 as follows.

Sophie [7]

The idea is to use the tangent line to $f(x)=\sqrt x$ at $x=25$ in order to approximate $f(25.3)=\sqrt{25.3}$ .

We have

$f(x)=\sqrt x\implies f(25)=\sqrt{25}=5$

$f'(x)=\dfrac1{2\sqrt x}\implies f'(25)=\dfrac1{10}$

so the linear approximation to $f(x)$ is

$L(x)=f(5)+f'(5)(x-5)=5+\dfrac{x-5}{10}=\dfrac x{10}+\dfrac92$

Hence $m=\frac1{10}$ and $b=\frac92$ .

Then

$f(25.3)\approx L(25.3)=\dfrac{25.3}{10}+\dfrac92=\boxed{7.03}$
