You want to calculate the interest on $2000 at5.8% interest per month after six years?

Here is your formula: I =p*r*t

P is the principal amount which is $2000

R is the rate of interest which is 5.8% per month

T is the time involved whihc is six years

You’re interest is 8352.00

If a concrete mix contains 1-1/2 cubic feet of gravel, 1/2 cubic foot of water,

Karolina [17]

Answer:

The correct answer is "50%".

Step-by-step explanation:

The given values are:

Gravel,

= $(1-\frac{1}{2} )$

Water,

= $\frac{1}{2}$

Cement,

= 1

Sand,

= 2

Now,

The total mixture will be:

= $Gravel+Water+Cement+Sand$

By substituting the values, we get

= $(1-\frac{1}{2} )+\frac{1}{2} +1+2$

= $\frac{1}{2} +\frac{1}{2} +1+2$

= $4 \ cubic \ feet$

hence,

The percentage of sand will be:

= $\frac{Sand}{Total}\times 100$

= $\frac{2}{4}\times 100$

= $50$ %

A circle has a central angle measuring StartFraction 7 pi Over 10 EndFraction radians that intersects an arc of length 33 cm. Wh

NeTakaya

Answer:

15 cm.

Step-by-step explanation:

It is given that,

Central angle $=\dfrac{7\pi}{10}$

Arc length = 33 cm

Formula for arc length :

$s=r\theta$

where, s is arc length, r is radius and $\theta$ is central angle in radian.

Substitute s=33 and $\theta=\dfrac{7\pi}{10}$ in the above formula.

$33=r\left(\dfrac{7\pi}{10}\right)$

Multiply both sides by 10.

$330=7\pi r$

Divide both sides by $7\pi$ .

$\dfrac{330}{7\pi}= r$

Put $\pi=3.14$

$\dfrac{330}{7(3.14)}= r$

$15.0136= r$

$r\approx 15$

Therefore, the radius of the circle is 15 cm.

Step-by-step explanation:

Let x = Mikhail's age

then x-15 = Gabrielle's age

x + x-15 = 81

2x-15 = 81

2x = 96

x = 48 years old
