On Monday, jack and Jill walked from their house up the hill to get to the bus stop. They walked 4 yards every three seconds. Wr
never [62]

Answer: Our required equation will be

3d=4t

Step-by-step explanation:

Since we have given that

Jack and Jill walked 4 yards every three seconds

As we know that

Speed=\frac{Distance}{Time}\\\\Speed=\frac{4}{3}\text{ yards per seconds}\\

Now, we need to find the find the equation to represent  the distance,<em>d</em>,

Jack and Jill walked over time <em>t </em>.

So here it is,

Distance=Speed\times Time\\\\d=\frac{4}{3}\times t\\\\d=\frac{4}{3}t\\\\3d=4t

Hence, our required equation will be

3d=4t

Point C is the center of the circle. What is the measure of angle ACB if the measure of arc ADB is 312 degrees ?
creativ13 [48]

Answer:

Given: Point C is the center of circle.

To Find: ∠ A CB

Solution: Measure of arc A DB=312°

     Angle made by complete circle=360°

⇒∠A DB  + ∠ AC B= 360°[Total measure of complete circle]

⇒ 312°  + ∠ AC B= 360°

⇒∠ AC B = 360° - 312°

⇒ ∠ AC B=48°

The cube root of 0.000004913 is
Vlad1618 [11]

Answer:

\sqrt[3]{0.000004913}=0.017

Step-by-step explanation:

<u>Cubic Root </u>

The cubic root of a number N is M, if

M^3=N

It's usually tedious to manually compute cubic roots, but if we use some basic algebra concepts, the job is easily done.

Let's compute

M=\sqrt[3]{0.000004913}

The argument can be expressed in scientific notation as

0.000004913= 4913\ 10^{-9}

The power of 10 has an exact cubic root since the exponent is a multiple of 3. To find the cubic root of the mantissa, we note it's the triple product of 17, i.e.

4913=17*17*17=17^3

Thus our number is

M=\sqrt[3]{17^3\ 10^{-9}}=17\ 10^{-3}=0.017

We have then

\boxed{\sqrt[3]{0.000004913}=0.017}
