Casandra finds a treasure chest packed with metallic coins. The chest has a volume of 0.25^30.25 m

Mathematics

Answer:

Gold

Step-by-step explanation:

<em>Casandra finds a treasure chest packed with metallic coins. The chest has a volume of 0.25 cubic meters. The coins have a combined mass of 4825 kg. Hoping to find gold, she calculates the density to determine the metal of the coins.</em>

<em>What kind of metal are the coins made of?</em>

<em>Bronze (8700 kg per cubic meter)</em>

<em>Silver (10500 kg per cubic meter)</em>

<em>Lead (11300 kg per cubic meter)</em>

<em>Gold (19300 kg per cubic meter)</em>

<em />

Density is mass per volume:

D = M / V

D = (4825 kg) / (0.25 m³)

D = 19,300 kg/m³

The coins must be made of gold.

In a parallel circuit, ET = 208 V, R = 33 kΩ, and XL = 82 kΩ. What is the apparent power?
jeka94

Answer:

Apparent power is 1.413Volt-Amps.

Step-by-step explanation:

We are given that in a parallel circuit,E_{T}=208V,R=33kΩ and X_{L}=82kΩ.

And we are asked to find apparent power.

Apparent power is the combination of true power and reactive power.

In other words, we can say that in a power triangle apparent power is the hypotenuse where as true power and reactive powers are sides.

Let us find true power , reactive power first and the using Pythagorean theorem we can find apparent power.

True power=\frac{E_{T}^{2}}{R}=\frac{208^{2}}{33000}=1.311watts

Reactive power=\frac{E_{T}^{2}}{X_{L}}=\frac{208^{2}}{82000}=0.528VARs

Hence apparent power=\sqrt{1.311^{2}+0.528^{2}} =1.413VA

Julio is training for a swimming race. The first part of his training schedule is shown. Session 1 2 3 456 Swimming distance (mi
Volgvan

An arithmetic sequence is a sequence in which the difference between each consecutive term remains same (constant).  

The explicit formula for an arithmetic sequence is A_n=a+(n-1)d, where a is first term of sequence, d is the common difference between consecutive terms.

A) We can see from Julio's swimming distance that it is in arithmetic sequence as after every successive training session Julio's swimming distance increased by 0.30 miles.  

0.55-0.25=0.30

0.85-0.55=0.30

1.75-1.45=0.30

Therefore, we can see that Julio's training schedule is an arithmetic sequence.

B) Let us find Julio will take how many days to swim 2.95 miles by using explicit formula.

A_n=a+(n-1)d

Let us substitute our given information in above formula.

2.95=0.25+(n-1)0.30

2.95=+0.25+0.30n-0.30

2.95=0.30n-0.05

2.95+0.05=0.30n

3.00=0.30n  

n=\frac{3.00}{0.30}=10

We are told that Julio swims every two days, this implies that he would swim on alternate days. So he will swim 2.95 miles on 10*2 =20th day.

Let us find 20th day will be which day. As Julio started his training schedule on Tuesday, 20th day will be a Sunday. Therefore, Julio will swim for 2.95 miles on a Sunday.

What is the value of b in this equation (y^-9)^b=y^45
Degger [83]

Answer:

-5

Step-by-step explanation:

Using rules of exponents we can change this equation to

y ^ (-9 * b) = y^45

-9*b = 45

b = -5
