The value of y varies jointly with the values of x and z When x = 4 and z = 10, the value of y is 360.
Igoryamba

Answer:

A

Step-by-step explanation:

Joint variation is given by:

y=kxz

Where k is some constant.

We are given that y = 360 when x = 4 and z = 10. Therefore:

360=k(4)(10)

Solving for k:

40k=360\Rightarrow k=9

Therefore, our equation is:

y=9xz

Then when x = 5 and z = 12:

y=9(5)(12)=540

The answer is A.

A giraffe can run 40 meters per second what is its speed in miles per hour
lora16 [44]
Bearing in mind that, there are

60 seconds in 1 minute,
60 minutes in 1 hr,
1000 meters in 1 km,
and 1.609 km in 1 mile

\bf \cfrac{40\underline{m}}{\underline{s}}\cdot \cfrac{60\underline{s}}{\underline{min}}\cdot \cfrac{60\underline{min}}{hr}\cdot \cfrac{\underline{km}}{1000\underline{m}}\cdot \cfrac{mi}{1.609\underline{km}}\implies \cfrac{40\cdot 60\cdot 60\cdot  mi}{hr\cdot 1000\cdot 1.609}
\\\\\\
\cfrac{144000mi}{1609hr}\approx 89.496581\frac{mi}{hr}
