Answer:

1.47 years

Step-by-step explanation:

Given that,

The height of male elephant is given by the formula,

h=62.5\sqrt[3]{t} +75.8

If h = 275 cm, we need to find the age of the elephant.

Put h = 275 cm in the above formula,

275=62.5\sqrt[3]{t} +75.8\\\\275-75.8=62.5\sqrt[3]{t}\\\\199.2=62.5\sqrt[3]{t}\\\\t=1.47\ years

So, the required time be 1.47 years.

If you have 3 quarters, 5 dimes, and 2 nickels in
slamgirl [31]

Answer:

Step-by-step explanation:

No. Of quarters n(Q)= 3

No. Of dimes n(D) = 5

No. Of nickels n(N) = 2

Total T = 3+5+2 = 10

Prob(D) = n(D)/T = 5/10 = 1/2

Now there are 9 left since it is not replaced back

Prob(Q) = 3/9 = 1/3

Prob(D and Q) = 1/2 × 1/3 = 1/6

The parallelogram ABCD below, line AC is a diagonal, the measure of angle ABC is 40, and the measure of angle ACD is 57. What is
Strike441 [17]

Answer:

Using properties of parallelogram and angle sum property of a triangle in the figure as shown below in the attachment

In parallelogram ABCD, AC is a diagonal.

Given:  \angle ABC = 40^{\circ} and \angle ACD= 57^{\circ}

As, we know that opposite angles in parallelogram are equal.

therefore,

\angle ABC =\angle ADC= 40^{\circ}

Now, in ΔADC

Sum of the measures of angles in a triangle is 180 degree.

\angle ACD+ \angle ADC+\angle DAC =180^{\circ}

Substituting the values of \angle ADC= 40^{\circ} and  \angle ACD= 57^{\circ}  we have;

57^{\circ}+40^{\circ}+\angle DAC =180^{\circ}

or

97^{\circ}+\angle DAC =180^{\circ}

Subtract 97^{\circ} from both sides we get

\angle DAC =180 -97 =83^{\circ}

Therefore, the measure of angle CAD is 83^{\circ}.
