Answer.
5. B. 4
6. sq. root of 2
7. C. 8
8. B. 13
9. B. 12x12=144
10. C. 11
Explanation.

5. A perfect square is a number with a perfect square root. of the four numbers, 4 is a perfect square.

6. An irrational number is a number that cannot be expressed as the ratio of two integers. The square root of two is an example of this.

7. A square root is a number times itself, but you do not know what number is being multiplied. By testing all the options, we find that 8x8 is indeed 64.

8. A square root is a number times itself, but you do not know what number is being multiplied. By testing all the options, we find that 13x13 is indeed 169.

9. We know that a square root is when a number is multiplied my itself. 12x12 is 144 therefore the square root of 144 is 12.

10. Because the square root of 140 does not have an simple answer, we can estimate. The approximate answer is 11.83 which can round up to 12 if that answer is available, select it. If not, the answer is 11.
Hope this helps, let me know if it’s correct so others can use it.
Good luck.

A​ hot-air balloon is 140 ft140 ft above the ground when a motorcycle​ (traveling in a straight line on a horizontal​ road) pass
luda_lava [24]

Answer:

Step-by-step explanation:

Given

Balloon velocity is 14 ft/s upwards  

Distance between balloon and cyclist is 140 ft

Velocity of motor cycle is 88 ft/s

After 10 sec  

motorcyclist traveled a distance of d_c=88\times 10=880 ft

Distance traveled by balloon in 10 s

d_b=14\times 10=140 ft

net height of balloon from ground =140+140=280 ft[/tex]

at t=10 s

distance between cyclist and balloon is z=\sqrt{280^2+880^2}

z=923.47 ft

now suppose at any time t motorcyclist cover a distance of x m and balloon is at a height of h m

thus z^2=(88t)^2+(14t+140)^2

differentiating w.r.t time

\Rightarrow z\frac{\mathrm{d} z}{\mathrm{d} t}=14\cdot \left ( 14t+140\right )+88\cdot \left ( 88t\right )

\Rightarrow at\ t=10 s

\Rightarrow \frac{\mathrm{d} z}{\mathrm{d} t}=\frac{14\cdot \left ( 14t+140\right )+88\cdot \left ( 88t\right )}{z}

\Rightarrow \frac{\mathrm{d} z}{\mathrm{d} t}=\frac{14\times 280+88^2\times 10}{923.471}

\Rightarrow \frac{\mathrm{d} z}{\mathrm{d} t}=\frac{81,360}{923.471}=88.102\ ft/s

A study has demonstrated that the more television a person watches, the lower that person’s level of physical fitness. However,
ad-work [718]

Answer:

Option D

Step-by-step explanation:

The most valid conclusion here is that the fact that running on a treadmill allows for a greater physical fitness with the television watching deterring the effect of the exercise. In as much as he only watches TV when running, it is not enough to conclude that TV can cause less physical fitness for Pablo.
