A "cross section" is basically the two-dimensional face that you get when you cut a three-dimensional figure a certain way. For example, imagine you're buttering your bread. When you cut a pat of butter off, what shape is left on the butter? A square!

So, imagine cutting a ball in half. What shape is left? A circle!

Answer: circle

If you roll two fair six-sided dice, what is the probability that at least one die shows a 333?

Vesna [10]

Answer:

1/3(0.3333333333%)

Step-by-step explanation:

There are six sides, and you can only land on one at a time on each die, so there is a one-in-three chance of landing on a three.

Find the annual interest rate.

slega [8]

The annual interest rate is 3.5%.

Solution:

Given Interest (I) = $26.25

Principal (P) = $500

Time (t) = 18 months

Rate of interest (r) = ?

Time must be in years to find the rate per annum.

1 year = 12 months

Divide the time by 12.

Time (t) = $\frac{18}{12}=\frac{3}{2}$ years

Now, find the rate of interest using simple interest formula.

<u>Simple interest formula:</u>

$$I=\frac{Prt}{100}$

$$26.25=\frac{500\times r\times \frac{3}{2} }{100}$

$$26.25\times 100 =500\times r\times \frac{3}{2}$

$$2625 =250\times r\times 3$

$$2625 =750\times r$

$$\Rightarrow r=\frac{2625}{750}$

⇒ r = 3.5%

Hence the annual interest rate is 3.5%.

The end of a hose was resting on the ground, pointing up an angle. Sal measured the path of the water coming out of the hose and

lawyer [7]

Functions can be used to model real life situations.

The hose is 3.2 feet above the ground, at a horizontal distance of 4 fee

The function is given as:

$f(x) =-0.3x^2 + 2x$

At a horizontal distance of 4 feet, the value of x is 4

i.e. $x = 4$

Substitute 4 for x in f(x).

So, we have:

$f(4) =-0.3(4)^2 + 2(4)$

Evaluate the exponent

$f(4) =-0.3(16) + 2(4)$

Open both brackets

$f(4) =-4.8 + 8$

Add -4.8 and 8

$f(4) =3.2$

Hence, the hose is 3.2 feet above the ground

G is between F and H, FG = 8, and FH = 12.<br> Find GH.<br> O GH= 4<br> O GH = 12<br> O GH = 5

ANEK [815]

Answer:

GH = 4

Step-by-step explanation:

Since G is between F and H then

FG + GH = FH , that is

8 + GH = 12 ( subtract 8 from both sides )

GH = 4
