The mass of full grown giraffe is 372.42 kg and mass of full grown lion is 62.07 kg and mass of full grown cheetah is 15.51 kg

Solution:

Let "a" be the mass of full grown giraffe

Let "b" be the mass of full grown lion

Let "c" be the mass of full grown cheetah

A full-grown giraffe is about 6 times heavier than a full-grown lion

a = 6b ------- eqn 1

A full-grown cheetah is about one-quarter as heavy as a full-grown lion

\begin{gathered}c = \frac{1}{4} \times b\\\\c = \frac{b}{4} ----- eqn\ 2\end{gathered}

c=

4

1

×b

c=

4

b

−−−−−eqn 2

Together, they are about 450 kg

Therefore,

a + b + c = 450

Substitute eqn 1 and eqn 2 in above

\begin{gathered}6b + b + \frac{b}{4} = 450\\\\24b + 4b + b = 450 \times 4\\\\29b = 1800\\\\b = 62.07\end{gathered}

6b+b+

4

b

=450

24b+4b+b=450×4

29b=1800

b=62.07

Substitute b = 62.07 in eqn 1

\begin{gathered}a = 6(62.07)\\\\a = 372.42\end{gathered}

a=6(62.07)

a=372.42

Substitute b = 62.07 in eqn 2

c = \frac{62.07}{4} = 15.51c=

4

62.07

=15.51

Thus, mass of full grown giraffe is 372.42 kg and mass of full grown lion is 62.07 kg and mass of full grown cheetah is 15.51 kg

Suppose b is any integer. If b mod 12 = 5, then 7b mod 12
Rzqust [24]

The result follows directly from properties of modular arithmetic:

b\equiv5\pmod{12}\implies 7b\equiv35\equiv-1\equiv\boxed{11}\pmod{12}

That is,

b\equiv5\pmod{12}

means we can write b=12n+5 for some integer n. Then

7b=7(12n+5)=12(7n)+35

and taken mod 12, the first term goes away, so

7b\equiv35\pmod{12}

etc

How to find the smallest integer k such that 60k is a perfect square
suter [353]

9514 1404 393

Answer:

  k = 15

Step-by-step explanation:

Look for the missing factors that make all of the factors of 60k be squares.

  60 = 2² × 3 × 5

The factors 3 and 5 each have an odd exponent (1), so those two factors must be part of k.

  60k = 2² × 3 × 5 × k

is a perfect square when ...

  3 × 5 = k = 15

For k = 15, 60k = 900 = 30²

A boat traveled 252 miles downstream and back. The trip downstream took 12 hours. The trip back took 84 hours. Find the speed of
Leokris [45]

Answer: the speed of the boat in still water is 12 mph and the speed of the current is 9 mph.

Step-by-step explanation:

Let x represent the speed of the boat in still water.

Let y represent the speed of the current.

The boat travelled 252 miles downstream and the same distance upstream.

The trip downstream took 12 hours. Assuming the boat travelled with the wind when going downstream, the total speed would be (x + y) mph.

Distance = speed × time

The expression for distance travelled downstream is

252 = 12(x + y)

Dividing through by 12, it becomes

21 = x + y- - - - - - - - - - 1

The trip back took 84 hours. Assuming the boat travelled against the wind when going back(upstream), the total speed would be (x - y) mph.

The expression for distance travelled upstream is

252 = 84(x - y)

Dividing through by 84, it becomes

3 = x - y- - - - - - - - - - 2

Adding equation 1 to equation 2, it becomes

24 = 2x

x = 24/2

x = 12 mph

Substituting x = 12 into equation 1, it becomes

21 = 12 + y

y = 21 - 12

y = 9 mph
