Answer:

Babatunde weigh on the Moon would be 124.8 N

Step-by-step explanation:

* The wight of an object on the earth is mg , where m is the the

  mass of the object in kg and g is the acceleration of gravity which

  is 9.8 m/s²

* The mass of an object on earth is the same as the mass of the

  same object on the moon but the weight of the object on the

  earth is different from the weight of the same object on the

  moon because the gravity on the earth different from on the moon

* The wight on the moon is mg , where m is the the mass of the

  object in kg and g is gravitational field strength on the Moon

  which is 1.6 N/kg

∵ Babatunde has a mass of 78 kg

∵ The mass on the moon = the mass on the earth

∵ On the moon the gravitational field strength is 1.6N/kg

∵ Weight = mg

∴ Babatunde weigh = 78 × 1.6 = 124.8 N

* Babatunde weigh on the Moon would be 124.8 N

A backyard pool has a concrete walkway around it that is 3 feet wide on all sides. The total area of the pool and the walkway is
Sloan [31]

Answer:

x \approx 21.080\,ft, y = 29.080\,ft

Step-by-step explanation:

The total area of the pool and the walkway is:

(x + 6\,ft)\cdot (y + 6\,ft) = 950\,ft^{2}

(x + 6\,ft)\cdot (x + 14\,ft) = 950\,ft^{2}

x^{2} + 20\cdot x + 84\,ft^{2} = 950\,ft^{2}

x^{2} + 20\cdot x - 866\,ft^{2} = 0

The roots of the second-order polynomial is:

x_{1} \approx 21.080\,ft and x_{2} \approx -41.081\,ft

The only possible root is:

x \approx 21.080\,ft

The other dimension of the pool is:

y = x + 8\,ft

y = 21.080\,ft + 8\,ft

y = 29.080\,ft

Write the equation of a line, in slope-intercept form, that has a slope of m=9 and passes through the point (4, 31) .
Zinaida [17]

Answer:

\sf y=9x-5

Step-by-step explanation:

\begin{aligned}&\sf y-y_1=m(x-x_1) \\&\sf y-31=9(x-4) \\&\sf y-31=9x-36 \\&\sf y=9x-36+31 \\&\boxed{\sf y=9x-5} \end{aligned}

Which of the following points are on the line given by the equation y equals 2x?
Rina8888 [55]

Answer:

(5,10)

(3,6)

Step-by-step explanation:

The equation y=2x means that 2 multiplied by the first value would equal the second value, so this means that the second value is twice as much as the first value.  This is not true for the first option because 8 is not twice of 16, and this is the same for (4,6), (4,2), and (1,3).  Therefore (5,10) and (3,6) work.
